D. Risk Factors

Investing in our ordinary shares involves a high degree of risk and uncertainty. You should carefully consider the risks and uncertainties described below before investing in our ordinary shares. If any of the following risks actually occurs, our business, prospects, financial condition and results of operations could be harmed. In that case, the value of our ordinary shares could decline, and you could lose all or part of your investment.

Risks Relating to Our Business

Our quarterly financial performance is likely to vary significantly in the future. Our revenues and operating results in any quarter may not be indicative of our future performance and it may be difficult for investors to evaluate our prospects.

Our quarterly revenues and operating results have varied significantly in the past and are likely to continue to vary significantly in the future. Fluctuations in our quarterly financial performance may result from the fact that we may receive a small number of relatively large orders in any given quarter. Because these orders generate disproportionately large revenues, our revenues and the rate of growth of our revenues for that quarter may reach levels that may not be sustained in subsequent quarters. In addition, some of our products have lengthy sales cycles. For example, it typically takes from three to 12 months after we first begin discussions with a prospective customer before we receive an order from that customer. We also have a very limited order backlog, if any, which makes revenues in any quarter substantially dependent upon orders we deliver in that quarter. Because of these factors, our revenues and operating results in any quarter may not meet market expectations or be indicative of future performance and it may be difficult for investors to evaluate our prospects.

Our future success will be largely dependent of the acceptance of our high definition video conferencing room endpoint systems. If these solutions are not accepted, our business, results of operations and financial condition will be adversely affected.

In February 2010, we acquired certain assets of Aethra Video Srl and Aethra SpA of Ancona, Italy, or Aethra, including certain intellectual property and technology for high definition, or HD, video conferencing endpoint systems. In April 2010, we announced the SCOPIA XT1000 series HD video conferencing room system series, which was the first development based on our acquisition of the Aethra endpoint technology. In June 2010, we announced the SCOPIA XT1000 series SMB solution, an HD video conferencing solution especially suited to the communication requirements of small and medium businesses. This solution combines the capabilities of the SCOPIA XT1000 series HD video conferencing room systems with our SCOPIA Desktop software to fully extend the SCOPIA XT1000 series room systems’ experience to users anywhere on their Macs or PCs. Our future success will be in great measure dependent on the acceptance of our HD video conferencing endpoint systems. If these solutions are not accepted, our business, results of operations and financial condition will be adversely affected.

We rely on a small number of marketing partners who distribute our products either under our name or as private label products for a significant portion of our business.

We rely in great measure on original equipment manufacturers, or OEMs (mainly Cisco), systems integrators and value added resellers, or VARs, to sell our products. Our OEM customers typically may purchase our products to integrate with products that they developed in-house to build complete IP communication solutions. Our systems integrator customers either purchase our full suite of products or integrate our individual products with those of other manufacturers in order to build complete IP communication solutions. Our VAR customers purchase our products to resell to end-users as separate units, or as part of a family of related product offerings, either under our RADVISION label or under their private label. If we are unable to maintain these marketing partners or obtain new marketing partners, our future revenues and profitability will be affected and we may lose market share.

Cisco (NASDAQ: CSCO) accounted for approximately 39%, 42% and 34% of our sales in 2008, 2009 and 2010, respectively. In April 2010, Cisco completed the acquisition of TANDBERG, one of our principal competitors. The full TANDBERG product line is now part of the Cisco TelePresence portfolio. Our agreement with Cisco continues on a year to year basis and either party may terminate the relationship no later than 90 days prior to the expiration of the then current term. We expect that our sales to Cisco will decline significantly in 2011. In addition, our OEM agreement with LifeSize (acquired by Logitech), which was formerly one of our major OEM arrangements, was terminated on February 18, 2011.

Major solutions providers who currently work with us might compete with us in the future.

In addition to Cisco, we currently offer our technology either directly to or in association with major solutions providers such as IBM, Siemens, Telstra and others. Some of these companies also purchase technology from our competitors. If any of these solutions providers choose to develop their own technologies that compete with ours, acquire technologies from our competitors or acquire our competitors, our financial condition and operating results could be adversely impacted and we may face increased competition from these major companies.

Our agreements with our customers generally do not have minimum purchase requirements. If our customers cease to purchase or reduce their purchases of our products and technology, our revenues will decline.

Our agreements with our customers generally do not have minimum purchase requirements. If any or all of our customers cease to purchase or reduce their purchases of our products and technology at any time, our revenues will decline. Our customers may choose to independently develop for themselves, or purchase from others, products and technology similar to our products and technology. Moreover, if our customers do not successfully market and sell the systems and products into which they incorporate our products and technology, the demand of these customers for our products and technology will decline. Our customers’ sales of systems and products containing our products and technology may be adversely affected by circumstances over which we have no control and over which our customers may have little, if any, control.

If the use of packet-based networks as a medium for real-time voice, video and data communication does not continue to grow, the demand for our products and technology will slow and our revenues will decline.

Our future success depends on the growth in the use of packet-based networks, including the Internet and other IP networks, as a medium for real-time voice, video and data communication. If the use of packet-based networks does not expand, the demand for our products and technology will slow and our revenues will decline. Market acceptance of packet-based networks as a viable alternative to circuit-switched networks for the transmission of real-time voice and video communication is not proven and may be inhibited by concerns about quality of service and potentially inadequate development of the necessary infrastructure.

We must develop new products and technology and enhancements to existing products and technology to remain competitive. If we fail to do so, we may lose market share to our competitors and our revenues may decline.

The market for our products and technology is characterized by rapid technological change, new and improved product introductions, changes in customer requirements and evolving industry standards. Our research and development team may not be as large as those of our competitors, which may result in longer lead times to develop and implement new technologies and may limit our ability to compete effectively with them and may result in our losing market share. Our future success will depend to a substantial extent on our ability to:

timely identify new market trends; and

develop, introduce and support new and enhanced products and technology on a successful and timely basis.

We may not be successful in developing new products and technology and enhancements to our existing products and technology. If we fail to develop and deploy new products and technology or product and technology enhancements on a successful and timely basis, we may lose market share to our competitors and our revenues may decline.

We have invested, and will continue to invest, in products and technology that comply with those industry standards that we believe have been, or will be, broadly adopted. If one or more alternative standards were to gain greater acceptance than the standards that we believe have or will be broadly adopted, sales of our products and technology would suffer.

Our current suite of IP communication protocol toolkits includes, among others, H.323, SIP (session initiation protocol), and SIP IMS (session initiation protocol IP multimedia subsystem), SIP for VoLTE (session initiation Protocol for voice over long-term evolution), NAT (network address translation) Traversal, Diameter, MGCP (media gateway control protocol) and MEGACO (media gateway control protocol for large-scale IP-centric communication networks), 3G-324M protocol for real time multimedia services over 3G (Third Generation) networks and our BEEHD family of products designed for Android-based mobile and tablet devices, desktop software clients and an embedded solution for Texas Instruments digital signal processors, or DSPs. If future IP networks are not designed with components built around these protocols, or if one or more alternative protocols were to gain greater acceptance than these protocols, our investments may be of little or no value and sales of our products and technology would suffer.

Competition in the markets for our products and technology is intense. We may not be able to compete effectively in these markets and we may lose market share to our competitors. Some of our competitors have greater resources than we do, which may limit our ability to compete effectively and discourage customers from purchasing our products and technology.

The markets for our products and technology are highly competitive and we expect competition to intensify in the future. The principal competitors in the market for our Video Business Unit currently include Polycom Inc., TANDBERG (owned by Cisco), LifeSize (owned by Logitech) and Vidyo. The principal competitors in the market for our Technology Business Unit products currently include Aricent, Data Connection Limited, M5T ENEA (which acquired Netbrics), Trillium Digital Systems (acquired by Continuous Computing), CounterPath, Mirial, Spirit DSP, open source technologies and in-house developers employed by manufacturers of telecommunication equipment and systems. Additional competitors may enter each of our markets at any time. Moreover, our customers may seek to develop internally the products that we currently sell to them and compete with us. We may not be able to compete effectively in these markets, and we may lose market share to our competitors.

Some of our competitors have greater financial, personnel and other resources than we do, which may limit our ability to compete effectively with them. These competitors may be able to respond more quickly to new or emerging technologies or changes in customer requirements. These competitors may also benefit from greater economies of scale, offer more aggressive pricing or devote greater resources to the promotion of their products. Any of these advantages may discourage customers from purchasing our products and technology. If we are unable to compete successfully against our existing or potential competitors, our revenues and margins will decline.

Our software development kit revenues will decrease if our customers choose to use open source software that is available for free.

Both Vovida Networks, Inc., a subsidiary of Cisco Systems Inc., and Open H.323 offer H.323 source code for free. In addition, Vovida Networks, Inc. offers MGCP and SIP source code for free and HP offers its SIP testing tool (SIPp) for free. Other companies, including Microsoft and Nokia, may offer similar development kits as part of their product offerings. There are other open source toolkits for SIP (SIP foundry) and Diameter (OpenDiameter). If our customers choose to use the free source code offered by any of these organizations instead of purchasing our technology, our revenues from the sale of our software development kits will decline.

Undetected errors may increase our costs and impair the market acceptance of our products and technology.

Our products and technology have occasionally contained, and may in the future contain, undetected errors when first introduced or when new versions are released. Our customers integrate our products and technology into systems and products that they develop themselves or acquire from other vendors. As a result, when problems occur in equipment or a system into which our products or technology have been incorporated, it may be difficult to identify the cause of the problem. Regardless of the source of these errors (whether the source is our products or technology or the products of another vendor), we must divert the attention of our engineering personnel from our research and development efforts to address the errors. We may incur warranty or repair costs, be subject to liability claims for damages related to product errors or experience delays as a result of these errors in the future. Any insurance policies that we may have, may not provide sufficient protection or coverage should a claim be asserted. Moreover, the occurrence of errors, whether caused by our products or technology or the products of another vendor, may result in significant customer relations problems and injury to our reputation and may impair the market acceptance of our products and technology.

We may encounter difficulties in realizing the potential financial or strategic benefits of our acquisition of certain Aethra assets and from future acquisitions.

In February 2010, we acquired certain assets of Aethra, including certain intellectual property and technology for HD video conferencing endpoint systems. In April 2010, we announced the SCOPIA XT1000 series HD video conferencing room system, which was the first development based on our acquisition of the Aethra endpoint technology. In June 2010, we announced the SCOPIA XT1000 series SMB solution, an HD video conferencing solution especially suited to the communication requirements of small and medium businesses.

We may make additional acquisitions in the future. The pursuit of potential acquisitions may divert the attention of management and cause us to incur various expenses in identifying, investigating, and pursuing suitable acquisitions, whether or not they are consummated. In addition, if we acquire additional businesses or assets, such as the Aethra assets, we may not be able to integrate the acquired personnel, operations, and technologies successfully or effectively manage the combined business following the completion of the acquisition. We may also not achieve the anticipated benefits from the acquired business due to a number of factors, including:

Unanticipated costs or liabilities associated with the acquisition;

Incurrence of acquisition-related costs;

Diversion of management’s attention from other business concerns;

Harm to our existing business relationships with manufacturers, distributors and customers as a result of the acquisition;

The potential loss of key employees;

Use of resources that are needed in other parts of our business;

Use of substantial portions of our available cash to consummate the acquisition; and

Unrealistic goals or projections for the acquisition.

Unfavorable national and global economic conditions could have a material adverse effect on our business, operating results and financial condition.

The 2008 and 2009 crisis in the financial and credit markets in the United States, Europe and Asia led to a global economic slowdown, with the economies of the United States and Europe showing significant signs of weakness. Although global economic conditions have stabilized or improved, there is continuing economic uncertainty. If the economies in any part of the remain uncertain or weaken further, the demand for our products and technology may decrease as a result of constraints on IT-related capital spending by our customers. In addition, this could result in longer sales cycles, slower adoption of new technologies and increased price competition for our products. Any of these events would likely harm our business, operating results and financial condition. If global economic and market conditions, or economic conditions in the United States, Europe or Asia or other key markets, remain uncertain or weaken further, our business, operating results and financial condition may be materially adversely affected.

On March 11, 2011, an earthquake off the eastern coast of Japan triggered a devastating tsunami tidal wave, causing damage and destruction. It is too early to predict the long-term impact of this disaster on the economy of Japan and elsewhere.

Our products may infringe on the intellectual property rights of others, which could increase our costs and negatively affect our profitability.

Third parties have asserted in the past and may assert in the future against us infringement claims or claims that we have infringed a patent, copyright, trademark or other proprietary right belonging to them. Some of these third parties have offered to license their intellectual property to our company. See Item. 8A. Financial Information - Consolidated Statements and Other Financial Information - Legal Proceedings.” Any infringement claim, even if not meritorious, could result in the expenditure of significant financial and managerial resources and could negatively affect our profitability. If there is a successful claim of product infringement against us and we are not able to license the infringed or similar technology, our business, operating results and financial condition would be materially and adversely affected.

We are dependent upon a limited number of suppliers of key components. If these suppliers delay or discontinue manufacture of these components, we may experience delays in shipments, increased costs and cancellation of orders for our products.

We currently obtain key components used in the manufacture of our products from a sole supplier or from a limited number of suppliers. We do not have long-term supply contracts with our suppliers. Any delays in delivery of or shortages in these components could interrupt and delay manufacturing of our products and result in the cancellation of orders for our products. In addition, these suppliers could discontinue the manufacture or supply of these components at any time. We may not be able to identify and integrate alternative sources of supply in a timely fashion or at all. Any transition to alternate suppliers may result in delays in shipment and increased expenses and may limit our ability to deliver products to our customers. Furthermore, if we are unable to identify an alternative source of supply, we would have to modify our products to use a substitute component, which may cause delays in shipments, increased design and manufacturing costs and increased prices for our products.

From time to time we issue irrevocable purchase orders to our suppliers. If market demand for our products declines, we may be required to recognize a provision for expected loss which may have a negative impact on our financial results.

We rely on third party technology and licenses. If we are unable to continue to license or purchase this technology on reasonable terms, we may face delays in releases of our products and may be required to reduce the functionality of our products derived from this technology.

We rely on technology that we license or procure from third parties, including software that is integrated with internally developed software and used in our products to perform key functions. If we are unable to continue to license any of this software on commercially reasonable terms or otherwise obtain the technology, we will face delays in releases of our products or will be required to reduce the functionality of our products until equivalent technology can be identified, licensed or developed, and integrated into our current products.

Third parties may infringe upon or misappropriate our intellectual property, which could impair our ability to compete effectively and negatively affect our profitability.

Our success depends upon the protection of our technology, trade secrets and trademarks. Our profitability could suffer if third parties infringe upon our intellectual property rights or misappropriate our technology and other assets or the intellectual property rights licensed from third parties. To protect our rights to our intellectual property, we rely on a combination of trade secret protection, trademark law, confidentiality agreements and other contractual arrangements. We rely on third parties to protect their intellectual property which is licensed to us, but we do not generally investigate to what extent such intellectual property is protected. The protective steps we have taken may be inadequate to deter infringement or misappropriation. We may be unable to detect the unauthorized use of our intellectual property or take appropriate steps to enforce our intellectual property rights. Policing unauthorized use of our products and technology is difficult. In addition, the laws of some foreign countries in which we currently sell or may in the future sell our products do not protect our proprietary rights to as great an extent as do the laws of the United States. Failure to adequately protect or to promptly detect unauthorized use of our intellectual property could devalue our proprietary content and impair our ability to compete effectively. Further, defending our intellectual property rights could result in the expenditure of significant financial and managerial resources, whether or not the defense is successful.

We are dependent on our senior management. Any loss of the services of our senior management could negatively affect our business.

Our future success depends to a large extent on the continued services of our senior management and key personnel. We do not carry key-man life insurance for any of our senior management. Any loss of the services of members of our senior management or other key personnel could negatively affect our business.

Capital market fluctuations may decrease the value of our assets and may cause us to incur impairment charges relating to our investment portfolio.

As of December 31, 2010, we had $50.8 million in short and long-term marketable securities. The performance of the capital markets affects the values of funds that are held in marketable securities. These assets are subject to market fluctuations and yield uncertain returns, which may fall below our projected return rates. For example, the 2008 and 2009 financial crisis resulted in immaterial impairments of the carrying value of a limited amount of our investment assets. Future turmoil in the capital markets may result in additional impairments. Realized or unrealized losses in our investments or in our other financial assets may adversely affect our financial condition.

In addition, any decline in the financial condition of U.S. or European banks or other financial institutions or increased regulation relating to their lending activities may adversely affect our ability to secure additional credit facilities, if needed. The unavailability of additional credit may prevent us from executing our future business plans, including potential acquisitions.

One of our primary market risk exposures is to changes in interest rates as a result of our investment in marketable securities. A decline in market interest rates could have an adverse effect on our financial income. In a declining interest rate environment, borrowers may seek to refinance their borrowings at lower rates and, accordingly, prepay or redeem securities we hold more quickly than we initially expected. This action may cause us to reinvest the redeemed proceeds in lower yielding investments. An increase in market interest rates could also have an adverse effect on the value of our investment portfolio, for example, by decreasing the fair value of the fixed income securities that comprise a substantial majority of our investment portfolio.

Our failure to retain and attract personnel could harm our business, operations and product development efforts.

Our products require sophisticated research and development, marketing and sales, and technical customer support. Our success depends on our ability to attract, train and retain qualified research and development, marketing and sales and technical customer support personnel. Competition for personnel in all of these areas is intense and we may not be able to hire sufficient personnel to achieve our goals or support the anticipated growth in our business. The market for the highly-trained personnel we require is very competitive, due to the limited number of people available with the necessary technical skills and understanding of our products and technology. If we fail to attract and retain qualified personnel, our business, operations and product development efforts would suffer.

Our non-competition agreements with our employees may not be enforceable. If any of these employees leaves us and joins a competitor, our competitor could benefit from the expertise our former employee gained while working for us.

We currently have non-competition agreements with our key employees in Israel. These agreements prohibit those employees, if they cease to work for us, from directly competing with us or working for our competitors. Under current U.S. and Israeli law, we may not be able to enforce these non-competition agreements. If we are unable to enforce any of these agreements, our competitors that employ our former employees could benefit from the expertise our former employees gained while working for us. In addition, we have non-competition agreements with only a limited number of employees outside of Israel, and we can not guarantee that such agreements are enforceable under applicable law.

We manufacture and maintain an inventory of customized products for some customers who have no obligation to purchase these products. If these customers fail to purchase these products, our financial results may be harmed.

To satisfy the timing requirements of some of our larger customers, we manufacture and maintain an inventory of certain of our products that we will customize to the specifications of these customers. The size of this inventory will be based upon the purchasing history and forecasts of these customers, which we currently estimate to be approximately two months of sales to these customers. Until we receive orders from our customers they have no obligation to purchase the inventoried products. If the customers for whom the inventoried products are manufactured do not purchase them, we may be required to modify the products for sale to others and may be unable to find other purchasers. In either event, the value of the products may be materially diminished which may have a negative impact on our financial results.

We depend on a limited number of manufacturing subcontractors with limited manufacturing capacity, and are exposed to the risk that these manufacturers may be unable to fulfill our orders on a timely basis and at the quality specifications that we require. As a result, we may not meet our customers’ demands, which could harm our business and results of operations.

We currently depend on a limited number of contract manufacturers with limited manufacturing capacity to manufacture our products. The assembly of certain of our finished products, the manufacture of custom printed circuit boards utilized in electronic subassemblies and related services are also performed by these independent subcontractors. Reliance on third party manufacturers exposes us to significant risks, including risks resulting from:

potential lack of manufacturing capacity;

limited control over delivery schedules;

quality assurance and control;

manufacturing yields and production costs;

voluntary or involuntary termination of their relationship with us;

difficulty in, and timeliness of, substituting any of our contract manufacturers, which could take as long as six months or more;

the economic and political conditions in their environment; and

their financial strength.

If the operations of our contract manufacturers are halted, even temporarily, or if they are unable to operate at full capacity for an extended period of time, we may experience business interruption, increased costs, loss of goodwill and loss of customers.

In addition, because we outsource the manufacture of most of our products, we are required to place manufacturing orders well in advance of the time when we expect to sell these products. In the event that we order the manufacture of a greater or lesser amount of these products than we will ultimately require, we are generally obligated to purchase the surplus products or to forego or delay the sale or delivery of the products that we did not order in advance. In either case, our business and results of operations may be adversely affected. Any of these risks could result in manufacturing delays or increases in manufacturing costs and expenses. There may be an adverse affect on our profitability and consequently on our results of operations, if we incur increased costs.

Government regulation could delay or prevent product offerings, resulting in decreased revenues.

Our products are designed to operate with local telephone systems throughout the world and therefore must comply with the regulations of the Federal Communication Commission and other regulations affecting the transmission of voice, video and data over telecommunication and other media. Each time we introduce a new product, we are required to obtain regulatory approval in the countries in which it is offered. In certain cases, we rely on our resellers or other partners to obtain the appropriate regulatory approvals. In addition, we must periodically obtain renewals of the regulatory approvals for the use of our products in countries where we have already obtained approval. We cannot assure you that regulatory approval for our current products will be renewed or that regulatory approval for future products will be obtained. If we do not obtain the necessary approvals and renewals, we may be required to delay the sales of our products in those countries until approval for use is granted or renewed. This could result in decreased revenues.

We are also subject to laws relating to the use and disposal of hazardous materials in electrical and electronic equipment. For example, in January 2005, the European Parliament and the Council of the European Union adopted The Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment Regulations 2005, which restrict the use of certain hazardous substances in electrical and electronic equipment effective as of July 1, 2006. If we are unable to maintain compliance with those regulations, we may be denied the ability to sell our products in the European Union. This could result in decreased revenues, inventory write-offs and write-down provisions.

We may fail to maintain effective internal control over financial reporting in accordance with Section 404 of the Sarbanes-Oxley Act of 2002, which could have an adverse effect on our financial results and the market price of our ordinary shares.

The Sarbanes-Oxley Act of 2002 imposes certain duties on us and our executives and directors. Our efforts to comply with the requirements of Section 404 of the Sarbanes-Oxley Act of 2002 governing internal control and procedures for financial reporting, which started in connection with our 2006 Annual Report on Form 20-F, have resulted in increased general and administrative expense and a diversion of management time and attention, and we expect these efforts to require the continued commitment of significant resources. Section 404 of the Sarbanes-Oxley Act requires (i) management's annual review and evaluation of our internal control over financial reporting and (ii) a statement by management that its independent registered public accounting firm has issued an attestation report on our internal control over financial reporting, in connection with the filing of the Annual Report on Form 20-F for each fiscal year. We may identify material weaknesses or significant deficiencies in our assessments of our internal control over financial reporting. Failure to maintain effective internal control over financial reporting could result in investigation or sanctions by regulatory authorities and could have a material adverse effect on our operating results, investor confidence in our reported financial information and the market price of our ordinary shares.

Risks Relating to Our Ordinary Shares

Our share price has been volatile in the past and may decline in the future.

Our ordinary shares have experienced significant market price and volume fluctuations in the past and may experience significant market price and volume fluctuations in the future in response to factors such as the following, some of which are beyond our control:

quarterly variations in our operating results;

operating results that vary from the expectations of securities analysts and investors;

changes in expectations as to our future financial performance, including financial estimates by securities analysts and investors;

announcements of technological innovations or new products by us or our competitors;

announcements by us or our competitors of significant contracts, acquisitions, strategic partnerships, joint ventures or capital commitments;

changes in the status of our intellectual property rights;

announcements by third parties of significant claims or proceedings against us;

additions or departures of key personnel;

future sales of our ordinary shares; and

stock market price, competitor’s performances and volume fluctuations.

Domestic and international stock markets often experience extreme price and volume fluctuations. Market fluctuations, as well as general political and economic conditions, such as a recession or interest rate or currency rate fluctuations or political events or hostilities in or surrounding Israel, could adversely affect the market price of our ordinary shares.

In the past, securities class action litigation has been brought against a company following periods of volatility in the market price of its securities. We could potentially in the future be the target of similar litigation. Securities litigation could result in substantial costs and divert management's attention and resources.

There is a substantial risk that we are a passive foreign investment company, or PFIC, which will subject our U.S. investors to adverse tax rules.

Holders of our ordinary shares who are U.S. residents face income tax risks. There is a substantial risk that we are a passive foreign investment company, commonly referred to as PFIC. Our treatment as a PFIC could result in a reduction in the after-tax return to the holders of our ordinary shares and would likely cause a reduction in the value of such ordinary shares. For U.S. federal income tax purposes, we will be classified as a PFIC for any taxable year in which either (i) 75% or more of our gross income is passive income, or (ii) at least 50% of the average value of all of our assets for the taxable year produce or are held for the production of passive income. For this purpose, cash is considered to be an asset that produces passive income. As a result of our substantial cash position, we believe that there is a substantial risk that we qualified as a PFIC during the taxable year ended December 31, 2010, under a literal application of the asset test described above, which looks solely to the market value. We believe that there is a substantial risk that we will also qualify as a PFIC during the taxable year ending December 31, 2011. If we are classified as a PFIC for U.S. federal income tax purposes, highly complex rules would apply to U.S. holders owning ordinary shares. Accordingly, you are urged to consult your tax advisors regarding the application of such rules. United States residents should carefully read “Item 10E. Additional Information - Taxation, United States Federal Income Tax Consequences” for a more complete discussion of the U.S. federal income tax risks related to owning and disposing of our ordinary shares.

Our ordinary shares are traded on more than one market and this may result in price variations.

Our ordinary shares are traded on the NASDAQ Global Select Market and on the Tel Aviv Stock Exchange. Trading in our ordinary shares on these markets is made in different currencies (dollars on the NASDAQ Global Select Market and NIS on the Tel Aviv Stock Exchange), and at different times (resulting from different time zones, different trading days and different public holidays in the United States and Israel). Consequently, the trading prices of our ordinary shares on these two markets often differ. Any decrease in the trading price of our ordinary shares on one of these markets could cause a decrease in the trading price of our ordinary shares on the other market.

Risks Relating to Our Location in Israel

Political, economic and military instability in Israel may disrupt our operations and negatively affect our business condition, harm our results of operations and adversely affect our share price.

We are incorporated under the laws of, and our principal executive offices and manufacturing and research and development facilities are located in, the State of Israel. As a result, political, economic and military conditions affecting Israel directly influence us. Any major hostilities involving Israel, a full or partial mobilization of the reserve forces of the Israeli army, the interruption or curtailment of trade between Israel and its present trading partners, or a significant downturn in the economic or financial condition of Israel could have a material adverse effect on our business, financial condition and results of operations.

Since the establishment of the State of Israel in 1948, Israel and its Arab neighbors have engaged in a number of armed conflicts. A state of hostility, varying from time to time in intensity and degree, has led to security and economic problems for Israel. Major hostilities between Israel and its neighbors may hinder Israel’s international trade and lead to economic downturn. This, in turn, could have a material adverse effect on our operations and business. There has been an increase in unrest and terrorist activity in Israel, which began in September 2000 and which has continued with varying levels of severity through 2010. In recent years, there was an escalation in violence among Israel, Hamas, the Palestinian Authority and other groups. Recently, countries in the region have experienced political instability, the effects of which are currently difficult to assess. Ongoing or future violence between Israel and the Palestinians, armed conflicts, terrorist activities, tension along Israel’s northern borders, or political instability in the region would likely disrupt international trading activities in Israel and may materially and negatively affect our business conditions and those of our major contract manufacturers and could harm our results of operations.

Furthermore, there are a number of countries, primarily in the Middle East, as well as Malaysia and Indonesia, that restrict business with Israel or Israeli companies, and we are precluded from marketing our products to these countries. Restrictive laws or policies directed towards Israel or Israeli businesses may have an adverse impact on our operations, our financial results or the expansion of our business.

Our results of operations may be negatively affected by the obligation of our personnel to perform military service.

Many of our officers and employees in Israel are obligated to perform annual reserve duty in the Israeli Defense Forces and may be called for active duty under emergency circumstances at any time. If a military conflict or war arises, these individuals could be required to serve in the military for extended periods of time. Our operations could be disrupted by the absence for a significant period of one or more of our executive officers or key employees or a significant number of other employees due to military service. Any disruption in our operations could adversely affect our business.

Our operations expose us to risks associated with fluctuations in foreign currency exchange rates that could adversely affect our business

Most of our revenues are in dollars or are linked to the dollar, while a portion of our expenses, principally salaries and related personnel expenses, were incurred in other currencies, particularly in NIS and Euro. Therefore, our costs in such other currencies, as expressed in U.S. dollars, are influenced by the exchange rate between the U.S. dollar and the relevant currency. During 2009 and 2010, the NIS appreciated against the U.S. dollar, which resulted in a significant increase in the U.S. dollar cost of our operations in Israel. While the NIS/dollar exchange rate was approximately the same at December 31, 2007 and 2008, the NIS fluctuated against the U.S. dollar during 2009 and 2010. We are also exposed to the risk that the rate of inflation in Israel will exceed the rate of depreciation of the NIS in relation to the dollar or that the timing of this depreciation lags behind inflation in Israel. This would have the effect of increasing the dollar cost of our operations. In the past, the NIS has devalued against foreign currencies, generally reflecting inflation rate differentials. We cannot predict any future trends in the rate of inflation in Israel or the rate of depreciation or appreciation of the NIS against the dollar. If the dollar cost of our operations in Israel increases, our dollar-measured results of operations will be adversely affected.

The tax benefits from our approved enterprise and beneficiary enterprise programs require us to satisfy specified conditions. If we fail to satisfy these conditions, we may be required to pay additional taxes and would likely be denied these benefits in the future.

The Investment Center of the Ministry of Industry, Trade and Labor of the State of Israel has granted approved enterprise status to two investment programs at our manufacturing facility and two programs qualify as beneficiary enterprises. The portion of our income derived from any of our approved enterprise programs and beneficiary enterprise programs, commencing when we begin to generate net income from these programs, is exempt from tax for a period of two years and will be subject to a reduced tax rate for an additional five to eight years, depending on the percentage of our share capital held by non-Israelis. The benefits available to an approved enterprise program and a beneficiary enterprise program are dependent upon the fulfillment of conditions stipulated in applicable law and, for an approved enterprise, the conditions contained in the certificate of approval from the Investment Center, and for our beneficiary enterprises, a pre-ruling that we received from the Israeli Tax Authority in October 2007. If we fail to comply with one or more of these conditions, we may be required to pay additional taxes during the period in which we would have benefited from the tax exemption or reduced tax rates and would likely be denied these benefits in the future.

Service and enforcement of legal process on us and our directors and officers may be difficult to obtain.

Service of process upon our directors and officers and the Israeli experts named in this annual report, most of whom reside outside the United States, may be difficult to obtain within the United States. Furthermore, since substantially most our assets, our directors and officers and the Israeli experts named in this annual report are located outside the United States, any judgment obtained in the United States against us or these individuals or entities may not be collectible within the United States.

There is doubt as to the enforceability of civil liabilities under the Securities Act and the Securities Exchange Act in original actions instituted in Israel. However, subject to certain time limitations and other conditions, Israeli courts may enforce final judgments of United States courts for liquidated amounts in civil matters, including judgments based upon the civil liability provisions of those Acts.

The rights and responsibilities of our shareholders are governed by Israeli law and differ in some respects from the rights and responsibilities of shareholders under U.S. law.

We are incorporated under Israeli law. The rights and responsibilities of holders of our ordinary shares are governed by our memorandum of association, articles of association and by Israeli law. These rights and responsibilities differ in some respects from the rights and responsibilities of shareholders in typical U.S. corporations. In particular, a shareholder of an Israeli company has a duty to act in good faith in exercising his or her rights and fulfilling his or her obligations toward the company and other shareholders and to refrain from abusing his power in the company, including, among other things, in voting at the general meeting of shareholders on certain matters. Israeli law provides that these duties are applicable in shareholder votes at the general meeting with respect to, among other things, amendments to a company’s articles of association, increases in a company’s authorized share capital, mergers and actions and transactions involving interests of officers, directors or other interested parties which require the shareholders’ general meeting’s approval. In addition, a controlling shareholder of an Israeli company or a shareholder who knows that he or she possesses the power to determine the outcome of a vote at a meeting of our shareholders, or who has, by virtue of the company’s articles of association, the power to appoint or prevent the appointment of an office holder in the company, or any other power with respect to the company, has a duty of fairness toward the company. However, Israeli law does not define the substance of this duty of fairness. There is little case law available to assist in understanding the implications of these provisions that govern shareholder behavior.

As a foreign private issuer whose shares are listed on the NASDAQ Global Select Market, we may follow certain home country corporate governance practices instead of certain NASDAQ requirements. We follow Israeli law and practice instead of NASDAQ rules regarding the requirement to obtain shareholder approval for certain dilutive events.

As a foreign private issuer whose shares are listed on the NASDAQ Global Select Market, we are permitted to follow certain home country corporate governance practices instead of certain requirements of The NASDAQ Listing Rules. We follow Israeli law and practice instead of The NASDAQ Listing Rules regarding the requirement to obtain shareholder approval for certain dilutive events (such as for the establishment or amendment of certain equity based compensation plans, an issuance that will result in a change of control of the company, certain transactions other than a public offering involving issuances of a 20% or more interest in the company and certain acquisitions of the stock or assets of another company). As a foreign private issuer listed on the NASDAQ Global Select Market, we may also follow home country practice with regard to, among other things, the composition of the board of directors, director nomination process, compensation of officers and quorum at shareholders’ meetings. A foreign private issuer that elects to follow a home country practice instead of NASDAQ requirements must submit to NASDAQ in advance a written statement from an independent counsel in such issuer’s home country certifying that the issuer’s practices are not prohibited by the home country’s laws. In addition, a foreign private issuer must disclose in its annual reports filed with the Securities and Exchange Commission each such requirement that it does not follow and describe the home country practice followed by the issuer instead of any such requirement. Accordingly, our shareholders may not be afforded the same protection as provided under NASDAQ’s corporate governance rules.

Provisions of Israeli law may delay, prevent or make difficult our acquisition by a third-party, which could prevent a change of control and therefore depress the price of our shares.

Provisions of Israeli corporate and tax law may have the effect of delaying, preventing or making more difficult a merger with, or other acquisition of, us. This could cause our ordinary shares to trade at prices below the price for which third parties might be willing to pay to gain control of us. Third parties who are otherwise willing to pay a premium over prevailing market prices to gain control of us may be unable or unwilling to do so because of these provisions of Israeli law.

ITEM 4. INFORMATION ON THE COMPANY

A. History and Development of the Company

We were incorporated under the laws of the State of Israel in January 1992, commenced operations in October 1992 and commenced sales of our products in the fourth quarter of 1994. We are a public limited liability company under the Israeli Companies Law, 5759-1999 and operate under that law and associated legislation. Our registered offices and principal place of business are located at 24 Raoul Wallenberg Street, Tel Aviv 69719, Israel, and our telephone number is +972-3-767-9300. Our address on the Internet is www.radvision.com. The information on our website is not incorporated by reference into this annual report.

We are a leading provider of high quality, scalable and easy-to-use products and technologies for unified visual communications, including video network infrastructure, developer tools, and HD room, desktop and mobile video conferencing systems. Hundreds of thousands of end-users around the world today communicate over a wide variety of networks using products and solutions based on or built around our multimedia communication platforms and software development solutions. We have over 600 customers worldwide using our Technology Business Unit products, including Alcatel-Lucent, Cisco, Comverse, Huawei, HTC, LG Electronics, LifeSize (acquired by Logitech), Microsoft, Nortel, NTT/DoCoMo, Orange Telecom, Philips, Quanta, Samsung, Siemens, Sony, Telecom Italia and Technicolor (formerly Thomson). Thousands of enterprises around the world and dozens of telecommunications operators are using our products, videoconferencing systems and solutions.

Since 2001, we have conducted our business through two separate business units, corresponding to our two product lines, to enable our product development and product marketing teams to respond quickly to evolving market needs with new product introductions.

Our Video Business Unit, or VBU, formerly referred to as our Networking Business Unit, or NBU, offers one of the broadest and most complete end-to-end videoconferencing solutions for IP, ISDN (integrated services digital network), SIP, H.323 and 3G-based networks in the industry today. These products are sold to businesses of all sizes and markets including the large and small enterprise market, government agencies and service providers.

We provide a complete offering for deployment of a videoconferencing solution, including video network infrastructure, desktop, conference room endpoint products and management software. We sell our products through a worldwide network of distributors, VARs, OEMs, and system integrators who use our products to develop and install advanced IP and ISDN-based visual communication solutions for use in the company meeting room and on employee’s desktops. We also sell our products and platforms to major vendors, such as Alcatel-Lucent, Cisco and IBM, which then integrate our solutions into their communications platforms and architectures. These integrated solutions enable the delivery of real-time interactive IP and 3G-based video telephony services over both broadband connections (such as cable and DSL) and 3G mobile networks. Over the years we expanded our offerings to include a software desktop solution through our acquisition of First Virtual Communications, Inc., or FVC, and its wholly-owned subsidiary, CUseeMe Networks, Inc., in March 2005 and a room video conferencing solution through our acquisition of selected assets from Aethra Video Srl and Aethra SpA in February of 2010.

Our Technology Business Unit, or TBU, is a one-stop-shop for video client frameworks and developer platforms that consumer electronics manufacturers, equipment vendors, integrators and service providers use to build and launch multimedia (voice, video, presence and messaging) products and services over IP, 3G, 4G and IP multimedia subsystem, or IMS, and long term evolution, or LTE, networks.

Our TBU software solutions include ready to use video client frameworks for mobile, desktop and embedded platforms including tablets and smart phones together comprising our BEEHD family of client products. The BEEHD client frameworks, which are sold to device manufacturers, service providers, systems integrators and application developers, allow them to quickly launch video communications products and solutions on multiple platforms. The BEEHD client frameworks are designed for both consumer based service provider 3G and 4G IMS or LTE networks as well as enterprise networks. Complementing this offering are our video testing solutions named VQ Monitor, eVident and ProLab for pre-deployment and post-deployment of video communication products in enterprises and service provider networks as well as video testing solutions for development and testing labs.

Our TBU also offers enabling technology to developers, including toolkits for SIP, Diameter, NAT Traversal, MEGACO/H.248,A/S-RTP, MGCP, H.323, RTSP (real time streaming protocol) and 3G-324M. Our TBU also offers an IMS and LTE development suite, which extends our existing toolkits to IMS for mobile, VolTE (Voice over LTE), fixed and cable implementations.

Both business units also assist customers to integrate our technology into their networks and products and to customize our products to their specific needs.

In February 2010, we acquired certain assets of Aethra, including certain intellectual property and technology for HD video conferencing endpoint systems. We had an OEM relationship with Aethra from 2005, through which our video infrastructure products and technology were included in Aethra video solutions, allowing Aethra to offer the market a complete end-to-end solution. The agreements for the acquisition were incorporated into Aethra’s pre-insolvency plan that was filed and admitted by the Italian court on January 25, 2010. The acquisition also includes the purchase of additional fixed assets and selected commercial agreements, which remains subject to the approval of the Italian court. The total transaction purchase price will be approximately $10.0 million (Euro 7.0 million), and we also assumed approximately $4.0 million (Euro 3.0 million) of liabilities. As of December 31, 2010, we have paid $7.0 million in cash and provided a $1.6 million irrevocable bank guarantee. As of such date we have also recorded $2.7 million of acquisition-related restructuring expenses. We have utilized Aethra’s HD video endpoint technology to bring to the market an HD room conferencing system which we launched in June of 2010, and we have integrated Aethra’s HD video technology into our video network infrastructure and desktop solutions to offer a full video conferencing portfolio in response to customer demand created by rapid change and consolidation in the video marketplace. We believe that the addition of Aethra’s technology assets will continue to enhance our existing video network infrastructure and desktop solutions to provide a more complete solution to enterprise customers.

Our capital expenditures for the years ended December 31, 2008, 2009 and 2010 were approximately $3.0 million, $2.1 million and $2.9 million, respectively. These expenditures were principally for research and development equipment, office furniture and equipment, leasehold improvements and implementation of an enterprise resource planning, or ERP, system.

As a result, our solutions support the most recent versions of each of the signaling protocols with the associated features they enable. In addition, our solutions are interoperable with nearly any standards-based endpoint on the market today.

· Scalable Video Coding (SVC) for network resiliency. We introduced SVC to our product line in 2009. SVC is an extension to the H.264 codec standard that is used by most of today’s video conferencing devices. SVC video technology allows video conferencing devices to send and receive multi-layered video streams composed of a small base layer and optional additional layers that enhance resolution, frame rate and quality. Layering provides a dramatically higher degree of error resiliency and video quality with no significant need for higher bandwidth. It is especially effective over networks with packet loss and/or that lack quality of service, typical of many wireless Internet networks.

With SVC, we enable full interoperability with existing devices while enjoying all the benefits of very high network error resiliency and high quality support for video conferencing room and telepresence systems. SVC will also improve the quality of connections between cascaded infrastructure devices (MCUs) and allow traditional endpoints without SVC capability to leverage the benefits of SVC.

· Desktop software client. Our desktop software client was enhanced in 2009 to provide video conferencing capabilities on the Mac platform in addition to the PC. The client provides capabilities to fully extend the video conferencing room system experience to the desktop including HD video, SVC, interoperable data collaboration and firewall traversal capabilities. It provides a very effective way to extend video communications beyond typical enterprise boundaries to workers at home and on the road.

This model provides access to high quality video conferencing capabilities extending the utility of a video conferencing deployment.

Visual Communication Market Trends Which May Benefit Our Company

Increased cost justification for video conferencing. The current conservative economic climate is causing companies to utilize more cost effective meeting solutions and video conferencing is proving to be a cost justifiable replacement for travel. HD solutions including telepresence are becoming affordable and provide a high quality replacement for long distance meetings.

HD has led to a better experience and perception of video conferencing. Video conferencing in the past has had a reputation for low quality and being difficult to use. The advent of HD video conferencing has dramatically improved the quality of the experience. The entry into the market by large enterprise vendors like Cisco, Microsoft and HP has led to increased awareness and improved perception of video conferencing and generated increased demand.

Workforce dynamics. Telecommuting, mobile workers and labor outsourcing are creating a more distributed workforce. Meetings are increasingly across different time zones and cultural boundaries and the use of video significantly helps bridge these barriers.

Unified communications in the workplace and at home. With the need for greater efficiency and the importance of accurate communication, companies are turning to new ways of communicating to enable remote parties to interact as if they were in the same room. Conference calls and e-mail usage have increased dramatically and instant messaging is increasingly being adopted in the enterprise. We believe that this trend of accessing all forms of communication from familiar applications is driving the unified communications experience and is making enterprises explore multimedia applications that provide advanced voice, video and data experiences to maximize information flow, whether in a group meeting or person to person.

Green initiatives. Due to increasing carbon foot-print awareness, companies are now, more than ever, looking for ways to find “greener” alternatives to air travel. We believe that the ever increasing quality of video technology and level of its maturity, the decreasing cost of bandwidth, the wider use of video conferencing in the enterprise and the ongoing reduction in the cost of endpoints, could all benefit us.

Despite our efforts to protect our proprietary rights, unauthorized parties may attempt to copy aspects of our products and technology or obtain and use information that we regard as proprietary. Policing unauthorized use of our products and technology is difficult. In addition, the laws of some foreign countries in which we currently or may in the future sell products to do not protect our proprietary rights to as great an extent as do the laws of the United States. Our means of protecting our proprietary rights may not be adequate and our competitors may independently develop similar technology, duplicate our products or design around our intellectual property.

We rely on certain technology that we license from third parties, including software that is integrated with internally developed software and used in our products to perform key functions. If we are unable to continue to license any of this software on commercially reasonable terms, we will face delays in releases of our products or will be required to reduce the functionality of our products until equivalent technology can be identified, licensed or developed, and integrated into our current products.

Competition

We compete in a new, rapidly evolving and highly competitive and fragmented market. We expect competition to intensify in the future. We believe that the main competitive factors in our market are time to market, product quality, features, cost, technological performance, scalability, compliance with industry standards and customer relationships.

The principal competitors in the market for our video business products are Cisco (which acquired Tandberg in 2010), LifeSize (acquired by Logitech in 2009), Polycom, Sony, Vidyo and various small or new market entrants.

The principal competitors in the market for our software development kit products currently include Aricent, Data Connection Limited, Dilithium Networks , M5T ENEA (which acquired Netbrics), Trillium Digital Systems (acquired by Continuous Computing) and open source developers and in-house developers employed by manufacturers of telecommunication equipment and systems.

ITEM 5. OPERATING AND FINANCIAL REVIEW AND PROSPECTS

A. Operating Results

The following discussion of our results of operations should be read together with our consolidated financial statements and the related notes, which appear elsewhere in this annual report. The following discussion contains forward-looking statements that reflect our current plans, estimates and beliefs and involve risks and uncertainties. Our actual results may differ materially from those discussed in the forward-looking statements. Factors that could cause or contribute to such differences include those discussed below and elsewhere in this annual report.

Background

We are a leading provider of products and technologies for unified visual communications, including video network infrastructure, developer tools, and HD room, desktop and mobile video conferencing systems. We were incorporated in January 1992, commenced operations in October 1992 and commenced sales of our products in the fourth quarter of 1994. Our ordinary shares are listed on the NASDAQ Global Select Market and the Tel Aviv Stock Exchange (symbol: RVSN).

Our consolidated financial statements appearing in this annual report are prepared in U.S. dollars and in accordance with U.S. generally accepted accounting principles, or U.S. GAAP, and audited in accordance with the standards of the Public Company Accounting Oversight Board (United States).

Our revenues are generated mainly in U.S. dollars or are linked to the dollar and a majority of our expenses is incurred in U.S. dollars. Consequently, we use the dollar as our functional currency. Transactions and balances in other currencies are re-measured into dollars according to the principles in Financial Accounting Standards Board, or FASB, Accounting Standards Codification, or ASC, 830 “Foreign Currency Matters.” Gains and losses arising from re-measurement are reflected in the statements of operations as financial income or expenses as appropriate.

Overview

We are one of the industry’s leading providers of products and technologies for unified visual communications, including video network infrastructure, developer tools, and high definition (HD) room, desktop and mobile video conferencing systems . Hundreds of thousands of end-users around the world today communicate over a wide variety of networks using products and solutions based on or built around our multimedia communication platforms and software development solutions. We have over 600 customers worldwide, including Alcatel-Lucent, Cisco, Comverse, Huawei, HTC, LG Electronics, LifeSize, Microsoft, Nortel, NTT/DoCoMo, Orange Telecom, Philips, Quanta, Samsung, Siemens, Sony, Telecom Italia, and Technicolor (formerly Thomson).

In February 2010, we acquired certain assets of Aethra, including certain intellectual property and technology for HD video conferencing endpoint systems. With the acquisition, we entered into the video conferencing endpoint market segment. Prior to the acquisition, we had an OEM relationship with Aethra from 2005, through which our video infrastructure products and technology were included in Aethra video solutions, allowing Aethra to offer the market a complete end-to-end solution. As a result of the Aethra acquisition, our expenses in several categories increased commensurate with the costs of operating and integrating the acquired businesses. These increases were primarily attributable to increases in personnel expenses and related costs correlating to increases in cost of revenues.

We have two separate business units, corresponding to our two product lines, to enable our product development and product marketing teams to respond quickly to evolving market needs with new product introductions.

Our VBU offers one of the broadest and most complete end-to-end videoconferencing solutions for IP, ISDN (integrated services digital network), SIP, H.323 and 3G-based networks in the industry today. These products are sold to businesses of all sizes and markets including the large and small enterprise market, government agencies and service providers. The VBU provides a complete offering for deployment of a videoconferencing solution, including video network infrastructure, desktop, conference room endpoint products and management software. We sell our products through a worldwide network of distributors, VARs, OEMs, and system integrators, who use our products to develop and install advanced IP and ISDN-based visual communication solutions for use in the company meeting room and on employee’s desktops. We also sell our products and platforms to major vendors, such as Alcatel-Lucent, Cisco and IBM, which then integrate our solutions into their communications platforms and architectures. These integrated solutions enable the delivery of real-time interactive IP and 3G-based video telephony services over both broadband connections (such as cable and DSL) and 3G mobile networks. Over the years we expanded our offerings to include a software desktop solution through our acquisition of FVC and its wholly-owned subsidiary, CUseeMe Networks, Inc., in March 2005, and a room video conferencing solution through our acquisition of selected assets from Aethra Video Srl and Aethra SpA in February of 2010.

Our TBU is a one-stop-shop for video client frameworks and developer platforms that consumer electronics manufacturers, equipment vendors, integrators and service providers use to build and launch multimedia (voice, video, presence and messaging) products and services over IP, 3G, 4G and IP IMS and LTE networks.

Our TBU software solutions include ready to use video client frameworks for mobile, desktop and embedded platforms including tablets and smart phones together comprising our BEEHD family of client products. The BEEHD client frameworks allow device manufacturers, service providers, integrators and application developers to quickly launch video communications products and solutions on multiple platforms. The BEEHD client frameworks are designed for both consumer based service provider 3G and 4G IMS or LTE networks as well as enterprise networks. Complementing this offering are our video testing solutions named VQ Monitor, eVident and ProLab for pre-deployment and post-deployment of video communication products in enterprises and service provider networks as well as video testing solution for development and testing labs.

Our TBU also provides enabling, technology for developers, including toolkits for SIP, Diameter, NAT Traversal, MEGACO/H.248,A/S-RTP, MGCP, H.323, RTSP (real time streaming protocol) and 3G-324M. Our TBU also offers an IMS and LTE development suite, which extends our existing toolkits to IMS for mobile, VoLTE, fixed and cable implementations.

Both business units also assist customers to integrate our technology into their networks and products and to customize our products to their specific needs.

Our goal is to develop and deliver market-leading technologies and products that drive widespread adoption and deployment of interactive unified visual communications over packet and next-generation networks. We provide solutions at every level - protocol developer toolkits, professional services, hardware-based network infrastructure, software-based desktop solutions, conference room video systems, as well as fully integrated solutions that complement the unified communication solutions of other vendors such as those from Alcatel-Lucent, Cisco, Huawei, IBM, LifeSize, Microsoft and Sony. We believe that our offering combinations of IP-centric videoconferencing products along with software toolkits, position us as a key enabling vendor in the evolution of V²IP communications (Video and Voice over IP).

Critical Accounting Policies and Estimations

We have identified the following policies as critical to the understanding of our financial statements. The preparation of our 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, revenue recognition, allowance for doubtful accounts, investment valuation, inventory valuation, goodwill and intangible assets, warranty, income tax valuation allowance, tax contingencies and uncertainties. Actual results could differ materially from these estimates.

Revenue Recognition. We account for our revenue in accordance with the provisions of ASC 985-605 “Software Revenue Recognition,” or ASC 985-605. When an arrangement does not require significant production, modification or customization of software or does not contain services considered to be essential to the functionality of the software, revenue is recognized when the following four criteria are met:

Persuasive evidence of an arrangement exists. We require evidence of an agreement with a customer specifying the terms and conditions of the products or services to be delivered typically in the form of a signed contract, statement of work or purchase order.

Delivery has occurred. For software licenses, delivery takes place when the customer is given access to the software programs via access to a website or shipped medium. For sales of videoconferencing systems that are delivered physically, delivery takes place upon transfer of the videoconferencing system to the customer’s possession. For services, delivery takes place as the services are provided.

The fee is fixed or determinable. Fees are fixed or determinable if they are not subject to a refund or cancellation and do not have payment terms that exceed our standard payment terms.

Collection is probable. We perform a credit review of all customers with significant transactions to determine whether a customer is credit worthy and collection is probable.

In general, revenues are recognized as follows: (i) revenues from license fees and sales of products are recognized when persuasive evidence of an arrangement exists, delivery has occurred, no significant obligations with regard to implementation remain, the fee is fixed or determinable and collectability is probable; (ii) maintenance and technical support is deferred and recognized on a straight-line basis over the term of the maintenance and support agreement; (iii) other services are recognized as the services are performed; (iv) revenues from royalties are recognized at the time of shipment by customers, as they are reported to us by those customers, and when collectability is probable; and (v) non-refundable payments on account of future royalties where no future obligation exists with regard to these royalties are recognized upon the signing of such arrangement and if collectability is probable.

We exercise judgment and use estimates in connection with the determination of the amount of product software license and services revenues to be recognized in each accounting period. If collection is not considered probable, revenue is recognized when the fee is collected. We record provisions against revenue for estimated sales returns and allowances on product and service-related sales in the same period as the related revenue is recorded. These estimates are based on historical sales returns and analyses of credit memo data, and other known factors. If the historical data we use to calculate these estimates do not accurately reflect future returns, adjustments to these reserves may be required that would increase or decrease revenue or net income.

Many of our arrangements include multiple elements. Such elements typically include any or all of the following: products or software licenses, software maintenance and technical support and in some cases customization and development of software services. For multiple-element arrangements that do not involve significant modification or customization of the software and do not involve services that are considered essential to the functionality of the software, revenues are allocated to the different elements in the arrangement under the “residual method” since vendor-specific objective evidence, or VSOE, of fair value exists for all undelivered elements and no VSOE exists for the delivered elements. Under the residual method, at the outset of the arrangement with the customer, we defer revenue for the fair value of our undelivered elements (usually maintenance and support) and recognize revenue for the remainder of the arrangement fee attributable to the elements initially delivered in the arrangement when all other criteria in ASC 985-605 have been met. Any discount in the arrangement is allocated to the delivered element. The VSOE of fair value of the maintenance and support services included in multiple element arrangements is determined based on the price charged when sold separately (i.e. when maintenance is renewed) and based on VSOE established by management for new products.

In the case of multiple-element arrangements that involve significant modification or customization of the software or involve services that are considered essential to the functionality of the software, contract accounting is applied according to the provisions of ASC 605-35 “Construction-Type and Production-Type Contracts,” or ASC 605-35 in accordance with which revenues are recognized on the percentage of completion basis, when collectability is probable. Percentage of completion is determined based on the “output method”, meaning upon completion of milestones. However, in cases where uncertainty exists subsequent to the completion of the milestone with regard to customer acceptance, revenue is not recognized until actual customer acceptance. The recognition of losses on uncompleted contracts is reflected in the period in which the likelihood of losses is identified.

Share-based payments. We applied ASC 718 “Compensation- Stock Compensation,” or ASC 718, which requires the measurement and recognition of compensation expense for all share-based payment awards made to employees and directors to be based on estimated fair values. ASC 718 requires companies to estimate the fair value of share-based payment awards on the date of grant using an option-pricing model. The value of the portion of the award that is ultimately expected to vest is recognized as expense over the requisite service periods in our consolidated statements of operations.

We selected the Black-Scholes-Merton model, which is the most common model in use in evaluating stock options. This model evaluates the options as if there is a single exercise point, and thus considers and expected option life (expected term). The input factored in this model is constant for the entire expected life of the option.

We recognize compensation expenses for the value of awards which have graded vesting based on the straight line method over the requisite service period of each of the awards, net of estimated forfeitures. ASC 718 requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The term “forfeitures” is distinct from “cancellations” or “expirations” and represents only the unvested portion of the surrendered option.

Expected volatility was calculated based upon actual historical stock price movements over a period equal to the expected term of the options. Estimated forfeitures are based on actual historical pre-vesting forfeitures. We derived the expected term assumption based on the provisions of SAB 110, which states that a company will determine its expected terms according to its historical exercise data for share option grants with sufficient exercise experience, except for options that were re-priced, for which the expected term of the options before the re-pricing was calculated using the binomial method. The risk-free interest rate is based on the yield from U.S. treasury bonds with an equivalent term. We have not historically paid dividends and have no foreseeable plans to pay dividends, therefore estimated dividend yield is 0%. For more information on the assumptions used for the calculation of the expense refer to Note 2r of our consolidated financial statements.

The total compensation cost related to options granted to employees under our share-based compensation plan recognized for the years ended December 31 2008, 2009 and 2010 amounted to $5.4 million, $4.3 million and $2.6 million, respectively.

Allowances for Doubtful Accounts. We perform ongoing credit evaluations of our customers’ financial condition, and we require collateral as deemed necessary. We maintain allowances for doubtful accounts for estimated losses resulting from the inability of our customers to make payments. In judging the adequacy of the allowance for doubtful accounts, we consider multiple factors including the aging of our receivables, historical bad debt experience and the general economic environment. Management applies considerable judgment in assessing the realization of receivables, including assessing the probability of collection and the current credit worthiness of each customer. If the financial condition of our customers were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances may be required.

Valuation of Investments. Fair value of marketable securities is estimated using quoted market prices where available. For securities not actively traded, fair value is estimated using values obtained from our cash asset managers or an independent valuation firm. To estimate the value of these investments, the cash asset managers or independent valuation firm employ various models that take into consideration such factors, among others, as the credit rating of the issuer, effective maturity of the security, yields on comparably rated publicly traded securities, availability of insurance and risk-free yield curves. The actual value at which such securities could actually be sold or settled with a willing buyer or seller may differ from such estimated fair value depending on a number of factors, including, but not limited to, current and future economic conditions, the quantity sold or settled, the presence of an active market and the availability of a willing buyer or seller.

On April 1, 2009, we adopted ASC 320. This guidance clarifies the interaction of the factors that should be considered when determining whether a debt security is other than temporarily impaired; provides guidance on the amount of other-than-temporary impairment recognized in earnings and other comprehensive income; and expands the disclosures required for other-than-temporary impairments for debt and equity securities. The guidance requires an entity to assess whether it intends to sell, or it is more likely than not that it will be required to sell a security before recovery of its amortized cost basis. If either of those criteria is met, the entire difference between amortized cost and fair value is recognized in earnings. For securities that do not meet these criteria, the amount of impairment recognized in earnings is limited to the amount related to credit losses, while an impairment related to other factors is recognized in other comprehensive income.

We adopted ASC 820, which establishes a framework for measuring fair value under generally accepted accounting principles and enhances disclosures about fair value measurements. Fair value is defined under ASC 820 as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value under ASC 820 must maximize the use of observable inputs and minimize the use of unobservable inputs. The adoption of this statement did not have a material impact on our consolidated results of operations and financial condition. See Note 2p to our consolidated financial statements.

Inventories. Inventories are stated at the lower of cost or market. Cost is determined by the average cost method. We write down obsolete or slow moving inventory in an amount equal to the difference between the cost of inventory and the estimated market value based upon assumptions about future demand, market conditions and sale forecasts. If actual market conditions are less favorable than we anticipate, additional inventory write-downs may be required.

Warranty Reserves. Upon shipment of products to our customers, we provide for the estimated cost to repair or replace products that may be returned under warranty. Our warranty period is typically 12 months from the date of shipment although this may vary depending on the demands of the customer. The reserve is estimated based on actual historical experience. Factors that may impact our warranty costs in the future include our reliance on our contract manufacturer to provide quality products and the fact that our products are complex and may contain undetected defects, errors or failures in either the hardware or the software.

Goodwill and Intangible Assets. Goodwill represents the excess of the purchase price over the fair value of identifiable net assets acquired in business combinations. The goodwill on our balance sheet is a result of our acquisitions of the assets of Aethra in February 2010, FVC in March 2005 and VisionNex Technologies, Inc., or VisionNex, in September 2004. The identifiable intangible assets, other than goodwill, included in our balance sheet as of December 31, 2010 are customer relationships, technology, distribution network and in process research and development acquired from Aethra. We review goodwill for potential impairment, according to a two-phase process for impairment testing, at least annually and other intangible assets when events or changes in circumstances indicate the carrying value of the other intangible assets may be impaired, in which case we may obtain an appraisal from an independent valuation firm to determine the amount of impairment, if any. In addition to the possible use of an independent valuation firm, we perform internal valuation analyses. Goodwill and intangible assets that resulted from the acquisitions of Aethra, FVC and VisioNex are allocated to the VBU segment and the goodwill impairment testing is performed at the reporting unit level. We determine fair value using widely accepted valuation techniques, including discounted cash flow analysis. This type of analysis requires us to make assumptions and estimates regarding industry economic factors and the profitability of future business strategies. It is our policy to conduct impairment testing based on our current business strategy in light of present industry and economic conditions, as well as future expectations. As of December 31, 2010, we determined there was no impairment of goodwill. If actual results are not consistent with our assumptions and estimates, we may be exposed to a goodwill impairment charge. In addition, we have compared our market capitalization based upon our closing share price as reported by NASDAQ, including an estimated control premium that an investor would be willing to pay for a controlling interest in us, to the fair value of our company based on the third party valuation study. The determination of a control premium requires the use of judgment and is based primarily on comparable industry and deal-size transactions, related synergies and other benefits.

In accordance with ASC 360 “Property, Plant and Equipment” and ASC 205 “Presentation of Financial Statements,” we perform tests for impairment of long-lived assets whenever events or circumstances suggest that other long-lived assets may not be recoverable. This analysis differs from our goodwill analysis in that impairment is only deemed to have occurred if the sum of the forecasted undiscounted future cash flows related to the assets are less than the carrying value of the asset we are testing for impairment. If the forecasted cash flows are less than the carrying value, then we are required to write down the carrying value to its estimated fair value based primarily upon forecasted discounted cash flows. As of December 31, 2010, no events or changes in circumstances indicating that other long-lived assets may not be recoverable were identified.

These forecasted undiscounted cash flows include estimates and assumptions related to revenue growth rates and operating margins, future economic and market conditions and determination of appropriate market comparables. Our estimates of market segment growth and our market segment share and costs are based on historical data, various internal estimates and certain external sources, and are based on assumptions that are consistent with the plans and estimates we are using to manage the underlying business. Our business consists of both established and emerging technologies, and our forecasts for emerging technologies are based upon internal estimates and external sources rather than historical information. If future forecasts are revised, they may indicate or require future impairment charges. We base our fair value estimates on assumptions we believe to be reasonable but that are unpredictable and inherently uncertain. Actual future results may differ from those estimates.

Deferred Taxes and Uncertain Tax Positions. We utilize the liability method of accounting for income taxes. We record a valuation allowance to reduce our deferred tax assets to the amount that we believe is more likely than not to be realized. In assessing the need for a valuation allowance, we consider all positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax planning strategies, changes to the applicable tax rate in Israel and recent financial performance. Forming a conclusion that a valuation allowance is not required is difficult when there is negative evidence such as cumulative losses in recent years. As a result of our cumulative losses in the United States and the full utilization of our loss carryforward opportunities, we have recorded valuation allowances to reduce our net deferred tax assets to the amount we believe is more likely than not to be realized. In the future, if we realize a deferred tax asset that currently carries a valuation allowance, we may record additional reduction to income tax expense in the period of such realization.

We apply ASC 740-10-55, which requires income tax positions to meet a more-likely-than-not recognition threshold to be recognized in the financial statements. ASC 740-10-55 contains a two-step approach to recognizing and measuring uncertain tax positions accounted for in accordance with FASB ASC 740 “Income Taxes.” The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon settlement. As a multinational corporation, we are subject to taxation in many jurisdictions, and the calculation of our tax liabilities involves dealing with uncertainties in the application of complex tax laws and regulations in various taxing jurisdictions. If we ultimately determine that the payment of these liabilities will be unnecessary, we reverse the liability and recognize a tax benefit during the period in which we determine the liability no longer applies. Conversely, we record additional tax charges in a period in which we determine that a recorded tax liability is less than we expect the ultimate assessment to be. The application of tax laws and regulations is subject to legal and factual interpretation, judgment and uncertainty. Tax laws and regulations themselves are subject to change as a result of changes in fiscal policy, changes in legislation, the evolution of regulations and court rulings. Therefore, the actual liability for U.S. or foreign taxes may be materially different from our estimates, which could result in the need to record additional tax liabilities or potentially reverse previously recorded tax liabilities.

Contingencies. We are involved in legal proceedings and other claims from time to time. We are required to assess the likelihood of any adverse judgments or outcomes to these matters, as well as potential ranges of probable losses. A determination of the amount of reserves required, if any, for any contingencies are made after careful analysis of each individual claim. The required reserves may change due to future developments in each matter or changes in approach, such as a change in the settlement strategy in dealing with any contingencies, which may result in higher net loss. If actual results are not consistent with our assumptions and judgments, we may be exposed to gains or losses that could be material. See “Item 8A. Financial Information – Consolidated Statements and Other Financial Information – Legal Proceedings.”

Revenues

We generate revenues from sales of our video business products and our technology products as well as related maintenance, support services and professional services. We price our video business products on a per unit basis. 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 and reseller channels in the Americas, Europe, the Middle East and the Asia-Pacific region.

Significant Expenses

Cost of Revenues. Our cost of revenues consists of component and material costs, direct labor costs, subcontractor fees, related overhead and depreciation and amortization. Our gross margin is affected by the selling prices for our products as well as the proportion of our revenues generated from the sale of our technology products as compared to our video business products. Our revenues from the sale of our technology products generally have higher gross margins than our revenues from the sale of our video business products In addition, within our VBU, our revenues from the sale of our infrastructure products have higher gross margins than revenues from the sale of our end point revenues. As the relative proportion of our revenues from our end point products increases as a percentage of our total revenues, our gross margins will decline.

Research and development expenses. Our research and development expenses consist primarily of compensation and related costs for research and development personnel, subcontractors, expenses for testing facilities and depreciation of equipment.

Research and development costs are charged to operations as incurred. Software development costs are considered for capitalization when technological feasibility is established. Costs incurred after achievement of technological feasibility in the process of software production have not been material. Therefore, we have not capitalized any of our research and development expenses.

Marketing and selling expenses. Our marketing and selling expenses consist primarily of compensation and related costs for sales personnel, marketing personnel, sales commissions, marketing programs, public relations, promotional materials, travel expenses and trade show exhibit expenses.

General and administrative expenses. Our general and administrative expenses consist primarily of salaries and related expenses for executive, accounting and human resources personnel, professional fees, provisions for doubtful accounts and other general corporate expenses.

Financial income, net. Our financial income, net consists primarily of interest earned on bank deposits and other liquid investments, gains and losses from the re-measurement of non-dollar exchange transactions and balances into dollars, other than temporary impairment of auction rate securities and amortization of marketable securities premium net of accretion of discounts.

Year Ended December 31, 2010 Compared with Year Ended December 31, 2009

Revenues. Revenues increased by 17.6% from $81.0 million for the year ended December 31, 2009 to $95.2 million for the year ended December 31, 2010. This increase in revenues was primarily attributable to increased demand for our video products, including our new endpoint products. VBU sales increased by $16.7 million compared to 2009, while TBU sales decreased by $2.4 million compared to 2009. The increase in VBU sales is mainly due to revenues from our new products, which include our endpoint and SCOPIA Elite product lines, which increase was off-set in part by a decrease in our OEM revenues.

Revenues from video products increased by 26.6% from $62.6 million for the year ended December 31, 2009 to $79.3 million for the year ended December 31, 2010. The increase in revenues from video products was primarily attributable to sales of endpoint and infrastructure product lines, which was off-set by a decrease of revenues from our OEM customers. Revenues from technology products decreased by 13.2% from $18.4 million for the year ended December 31, 2009 to $16.0 million for the year ended December 31, 2010. The decrease in revenues from technology products was attributable to a $1.0 million decrease in revenues from royalties, a $0.8 million decrease in revenues from license fees, a $0.4 million decrease in professional services fees and a $0.2 million decrease from maintenance fees.

Revenue from sales to customers in the Americas decreased from $50.6 million, or 62.5% of revenue, for the year ended December 31, 2009 to $49.7 million, or 52.2% of revenue, for the year ended December 31, 2010, a decrease of $0.9 million, or 1.8%. The decrease in sales to customers in the Americas was primarily attributable to a decrease in sales to Cisco, which decrease was offset by an increase in sales of our products to other purchasers in the Americas.

Revenue from sales to customers in Europe, the Middle East and Africa, or EMEA, increased from $14.4 million, or 17.8% of revenue, for the year ended December 31, 2009 to $23.5 million, or 24.6% of revenue, for the year ended December 31, 2010, an increase of $9.1 million, or 63.5%. The increase in sales to customers in EMEA was primarily attributable to an increase in sales of our VBU products, including endpoints and infrastructure product lines.

Revenue from sales to customers in the Asia-Pacific region increased from $16 million, or 19.8% of revenue, for the year ended December 31, 2009 to $22.1 million, or 23.2% of revenue, for the year ended December 31, 2010, an increase of $6.0 million, or 37.6%. The increase in sales to customers in the Asia-Pacific region is primarily attributable to an increase in sale of our VBU products, including endpoints and infrastructure product lines.

For the years ended December 31, 2008 and 2009, Cisco accounted for approximately 39% and 42%, respectively, of our sales. In April 2010, Cisco completed the acquisition of TANDBERG, one of our principal competitors. As a result of the acquisition, Cisco sales declined to 34% of our sales in 2010, and we expect Cisco sales to decline significantly in 2011.

Cost of Revenues. Cost of revenues increased from $17.4 million for the year ended December 31, 2009 to $26.3 million for the year ended December 31, 2010, an increase of $8.9 million, or 51.2%. Gross profit as a percentage of revenues was 78.6% for the year ended December 31, 2009 as compared to 72.4% for the year ended December 31, 2010. The decrease in our gross profit percentage is primarily attributable to a greater proportion of sales derived from our end point products, which have lower gross margins, compared to sales of our infrastructure products. We expect our gross margin to further decline in 2011 as a result of the anticipated increase in sales of our end point products. Cost of revenues for the years ended December 31, 2009 and 2010 includes $331,000 and $129,000, respectively, of stock-based compensation recorded under ASC 718.

Research and Development Expenses. Research and development expenses increased from $27 million for the year ended December 31, 2009, or 33.3% of revenues, to $30.9 million for the year ended December 31, 2010, or 32.5% of revenue, an increase of $3.9 million, or 14.7%. The increase in research and development expenses was primarily attributable to an increase in the number of research and development employees as a result of the Aethra assets acquisition and due to the appreciation of the NIS against the U.S. dollar, which increased the dollar value of our Israeli personnel expenses. Research and development expenses for the years ended December 31, 2009 and 2010 include $1.3 million and $930,000, respectively, of stock-based compensation recorded under ASC 718. We anticipate that research and development expenses will increase in 2011 as a result of the anticipated continued appreciation of the NIS against the U.S. dollar, which would increase the dollar cost of our Israeli personnel.

Marketing and Selling Expenses. Marketing and selling expenses increased from $27.6 million for the year ended December 31, 2009, or 34.1% of revenues, to $31.7 million for the year ended December 31, 2010, or 33.3% of revenues, an increase of $4.1 million, or 15.0%. The increase in marketing and selling expenses was primarily attributable to an increase in the number of sales and marketing employees, increased sales commission expenses due to increased revenues and the appreciation of the NIS against the U.S. dollar, which increased the dollar value of our Israeli personnel expense. Marketing and selling expenses for the years ended December 31, 2009 and 2010 include $1.6 million and $777,000, respectively, of stock-based compensation recorded under ASC 718. We anticipate that marketing and selling expenses will increase in 2011 as a result of our increased investment in sales and marketing, including our planned recruitment of additional sales personnel and investment of increased resources in marketing activities to promote our brand name.

General and Administrative Expenses. General and administrative expenses increased from $5.5 million for the year ended December 31, 2009, or 6.8% of revenues, to $6.1 million for the year ended December 31, 2010, or 6.3% of revenues, an increase of $0.6 million, or 10.3%. The increase in general and administrative expenses was primarily attributable to the appreciation of the NIS against the U.S. dollar, which increased the dollar value of our Israeli personnel expenses and due to expenses incurred in connection with the self tender offer for our company’s ordinary shares that we completed in September 2010. General and administrative expenses for the years ended December 31, 2009 and 2010 include $1 million and $790,000, respectively, of stock-based compensation recorded under ASC 718. We anticipate that general and administrative expenses will remain constant in 2011.

Acquisition-related restructuring expenses. We recorded acquisition-related restructuring expenses of $2.7 million for the year ended December 31, 2010, or 2.9% of revenue. Acquisition-related restructuring expenses consist of certain expenses that we are required to pay under Italian law relating to former employees of the Aethra video department, who are currently subject to the Italian Cassa Integrazione Guadagni Straordinaria, or CIGS, unemployment plan. Under the CIGS plan, such employees are entitled to unemployment benefits from the Italian government, and we are required to pay monthly social security payments and severance payments. We did not record any acquisition-related restructuring expenses for the year ended December 31, 2009.

Acquisition-related costs. In 2009 and 2010, we recorded $580,000 and $364,000, respectively, of acquisition-related legal and accounting costs that we incurred in connection with the acquisition of certain Aethra assets.

Financial Income, Net. Financial income, net decreased from $1.7 million for the year ended December 31, 2009 to $1.0 million for the year ended December 31, 2010. The decrease was primarily attributable to lower prevailing interest rates on securities, bonds and bank deposits and due to exchange rate differences, net. Financial income, net includes $554,000 and $306,000 of other than temporary impairment with respect to available for sale securities in 2009 and 2010, respectively. Financial income in 2009 and 2010 was primarily derived from the investment of the proceeds of our March 2000 initial public offering, cash generated from operating activities and exercise of options by employees, which was offset in part by the use of cash to repurchase our ordinary shares.

Tax Expense, Net. For the year ended December 31, 2010, we recorded income tax expense of approximately $1.6 million. The expense was primarily attributable to current foreign taxes expenses of approximately $1.2 million and prior years’ tax expenses of $532,000, offset in part by a $136,000 tax benefit resulting from an increase in deferred income tax assets. For the year ended December 31, 2009, we recorded income tax expense of approximately $5.5 million. The expense was primarily attributable to an increase in a valuation allowance of approximately $4.4 million due to uncertainty about our future revenues from Cisco, which were expected to decline gradually in 2010, as well as the effect on our profits if those revenues are not replaced. In addition, the income tax expense for 2009 included $719,000 of current foreign taxes and approximately $365,000 of prior years’ domestic tax expenses.

Year Ended December 31, 2009 Compared with Year Ended December 31, 2008

Revenues. Revenues decreased by 4.4% from $84.7 million for the year ended December 31, 2008 to $81.0 million for the year ended December 31, 2009. This decrease in revenues was primarily attributable to the global economic climate and credit crisis, which led to lower spending by customers. TBU sales decreased by $1.9 million compared to 2008 and VBU sales decreased by $1.8 million mainly in support services revenues.

Revenues from video business products decreased by 2.8% from $64.4 million for the year ended December 31, 2008 to $62.6 million for the year ended December 31, 2009. The decrease in revenues from networking products was primarily attributable to a decrease in maintenance and support sales and a decrease in revenues from our non Cisco channels, offset in part by an increase in revenues from Cisco. Revenues from technology products decreased by 9.4% from $20.3 million for the year ended December 31, 2008 to $18.4 million for the year ended December 31, 2009. The decrease in revenues from technology products was attributable to a $1.4 million decrease in revenues from license fees, $1.1 million decrease in revenues from maintenance and a 1.2 million decrease in revenues from royalties. The decrease was off-set in part by an increase of a $1.8 million in professional services fees.

Revenue from sales to customers in the Americas decreased from $52 million, or 61.4% of revenue, for the year ended December 31, 2008 to $50.6 million, or 62.5% of revenue, for the year ended December 31, 2009, a decrease of $1.4 million, or 2.7%. The decrease in sales to customers in the Americas was primarily attributable to decreased sales to our non-Cisco channels, which decrease was offset in part by an increase in sales to Cisco.

Revenue from sales to customers in Europe, the Middle East and Africa, or EMEA, decreased from $17.0 million, or 20.1% of revenue, for the year ended December 31, 2008 to $14.4 million, or 17.8% of revenue, for the year ended December 31, 2009, a decrease of $2.6 million, or 15.3%. The decrease in sales to customers in EMEA was primarily attributable to a decrease in sales of our networking products. Revenue from sales to customers in the Asia-Pacific region increased from $15.7 million, or 18.6% of revenue, for the year ended December 31, 2008 to $16 million, or 19.8% of revenue, for the year ended December 31, 2009, an increase of $300,000, or 2.0%. The increase in sales to customers in the Asia-Pacific region is primarily attributable to an increase in sales of our networking products to the 3G market.

Cost of Revenues. Cost of revenues decreased from $18.8 million for the year ended December 31, 2008 to $17.4 million for the year ended December 31, 2009, a decrease of $1.4 million, or 7.4%. Gross profit as a percentage of revenues was 77.8% for the year ended December 31, 2008 as compared to 78.6% for the year ended December 31, 2009. Cost of revenues for the years ended December 31, 2008 and 2009 includes $384,000 and $331,000, respectively, of stock-based compensation recorded under ASC 718.

Research and Development Expenses. Research and development expenses decreased from $36.9 million for the year ended December 31, 2008, or 43.5% of revenues, to $27 million for the year ended December 31, 2009, or 33.3% of revenues, a decrease of $9.9 million, or 26.8%. The decrease in research and development expenses was primarily attributable to the decrease in the number of research and development employees as a result of the cost reduction initiative that was implemented at the end of 2008 and early 2009. In addition, the dollar cost of our Israeli personnel expenses also decreased in 2009 as a result of the depreciation of the NIS against the U.S. dollar in such period. Research and development expenses for the years ended December 31, 2008 and 2009 include $1.5 million and $1.3 million, respectively, of stock-based compensation recorded under ASC 718.

Marketing and Selling Expenses. Marketing and selling expenses decreased from $35.3 million for the year ended December 31, 2008, or 41.7% of revenues, to $27.6 million for the year ended December 31, 2009, or 34.1% of revenues, a decrease of $7.7 million, or 21.8%. The decrease in marketing and selling expenses was primarily attributable to the decrease in the number of employees as a result of the cost reduction initiative that was implemented at the end of 2008 and early 2009. In addition, the dollar cost of our Israeli personnel expenses also decreased in 2009 as a result of the depreciation of the NIS against the U.S. dollar in such period. Marketing and selling expenses for the years ended December 31, 2008 and 2009 include $1.8 million and $1.6 million, respectively, of stock-based compensation recorded under ASC 718.

General and Administrative Expenses. General and administrative expenses decreased from $9.0 million for the year ended December 31, 2008, or 10.6% of revenues, to $5.5 million for the year ended December 31, 2009, or 6.8% of revenues, a decrease of $3.5 million, or 38.7%. The decrease in general and administrative expenses was primarily attributable to the decrease in the number of employees as a result of the cost reduction initiative that was implemented at the end of 2008 and early 2009. In addition, the dollar cost of our Israeli personnel expenses also decreased in 2009 as a result of the depreciation of the NIS against the U.S. dollar in such period. General and administrative expenses for the years ended December 31, 2008 and 2009 include $1.7 million and $1 million, respectively, of stock-based compensation recorded under ASC 718.

Acquisition-related costs. In 2009, we recorded $580,000 of acquisition-related legal and accounting costs that we incurred in connection with the acquisition of the Aethra assets. We did not record any acquisition-related costs in 2008.

Financial Income, Net. Financial income, net decreased from $2.5 million for the year ended December 31, 2008 to $1.7 million for the year ended December 31, 2009. The decrease was primarily attributable to lower interest rates on securities, bonds and bank deposits. Financial income, net includes $1.8 million and $554,000 other than temporary impairment of available for sale securities in 2008 and 2009, respectively. In addition, in 2008 auction rate securities classified as available for sale were redeemed at par value in the amount of $600,000, as a result of which net income in the amount of $376,000 was recorded as financial income, net. No auction rate securities were redeemed in 2009. Financial income in 2008 and 2009 was primarily derived from the investment of the proceeds of our March 2000 initial public offering, cash generated from operating activities and exercise of options by employees, which was offset in part by the use of cash to repurchase our ordinary shares.

Tax Benefit (Expense), Net. For the year ended December 31, 2008, we recorded an income tax expense of approximately $280,000. The expense was primarily derived from current tax expenses of approximately $690,000 and prior years’ tax expenses of approximately $357,000, offset by a $767,000 benefit resulting from an increase in deferred income tax assets. For the year ended December 31, 2009, we recorded an income tax expense of approximately $5.5 million. The expense was primarily attributable to an increase in a valuation allowance of approximately $4.4 million due to uncertainty about our future revenues from Cisco, which were expected to decline gradually in 2010, as well as the effect on our profits if those revenues are not replaced. In addition, the income tax expense for 2009 included $719,000 of current foreign taxes and approximately $365,000 of prior years’ domestic tax expenses.

Consolidated Balance Sheet Data

Trade Receivables. Trade receivables increased from $11.7 million at December 31, 2009 to $15.1 million at December 31, 2010, an increase of $3.4 million, or 29.2%. This increase was primarily attributable to the increase in our revenues.

Allowance for Doubtful Accounts. Allowance for doubtful accounts remained constant at $1.5 million at December 31, 2009 and December 31, 2010. Allowance for doubtful accounts as a percentage of trade receivables decreased from 12.6% as of December 31, 2009 to 10.0% as of December 31, 2010.

Other Receivables and Prepaid Expenses. Other receivables and prepaid expenses increased from $5.6 million at December 31, 2009 to $7.1 million at December 31, 2010, an increase of $1.5 million, or 27.6%. This increase was primarily attributable to Italian employee related payments under the CIGS unemployment plan, prepaid rent expenses and receivables from governmental authorities.

Inventories. Inventories increased from $1 million at December 31, 2009 to $2.6 million at December 31, 2010, an increase of $1.6 million, or 160.8%. The number of inventory days outstanding increased from approximately 19 days at December 31, 2009 to approximately 32 days at December 31, 2010. This increase was primarily attributable to the planned increase in inventory levels of our endpoint products in order to meet demand and shorten delivery lead times.

Trade Payables. Trade payables increased from $1.5 million at December 31, 2009 to $3.5 million at December 31, 2010, an increase of $2.0 million, or 137.2%. This increase was primarily attributable to increased manufacturing activities for our end point full turnkey solutions.

Other Payables, Accrued Expenses and Deferred Revenues. Other payables, accrued expenses and deferred revenues increased from $20.2 million at December 31, 2009 to $27.0 million at December 31, 2010, an increase of $6.8 million, or 33.6%. This increase was primarily attributable to a labor related accrual and other accrued payments related to certain liabilities assumed following the acquisition of Aethra.

Conditions in Israel

We are incorporated under the laws of, and our principal executive offices and manufacturing and research and development facilities are located in, the State of Israel. See Item 3.D. “Key Information – Risk Factors – Risks Relating to Our Location in Israel” for a description of governmental, economic, fiscal, monetary or political polices or factors that have materially affected or could materially affect our operations.

Trade Relations

Israel is a member of the United Nations, the International Monetary Fund, the International Bank for Reconstruction and Development, and the International Finance Corporation. Israel is a member of the World Trade Organization and is a signatory to the General Agreement on Tariffs and Trade. In addition, Israel has been granted preferences under the Generalized System of Preferences from the United States, Australia, Canada and Japan. These preferences allow Israel to export the products covered by such programs either duty-free or at reduced tariffs. In June 2010, Israel joined the Organization for Economic Co-operation and Development, or the OECD, an international organization whose members are governments of mostly developed economies. The OECD’s main goal is to promote policies that will improve the economic and social well-being of people around the world.

Israel and the European Union Community, known as the “European Union,” concluded a Free Trade Agreement in July 1975 that confers some advantages with respect to Israeli exports to most European countries and obligates Israel to lower its tariffs with respect to imports from these countries over a number of years. In 1985, Israel and the United States entered into an agreement to establish a Free Trade Area. The Free Trade Area has eliminated all tariff and some non-tariff barriers on most trade between the two countries. On January 1, 1993, an agreement between Israel and the European Free Trade Association, known as the “EFTA,” established a free-trade zone between Israel and the EFTA nations. In November 1995, Israel entered into a new agreement with the European Union, which includes a redefinition of rules of origin and other improvements, such as allowing Israel to become a member of the Research and Technology programs of the European Union. In recent years, Israel has established commercial and trade relations with a number of other nations, including Russia, China, India, Turkey and other nations in Eastern Europe and the Asia-Pacific region.

Impact of Currency Fluctuation and of Inflation

Most of our revenues generated outside of the United States are denominated in U.S. dollars. Costs not effectively denominated in U.S. dollars are remeasured into U.S. dollars, when recorded, at the prevailing exchange rates at the date of the transaction. Consequently, fluctuations in the rates of exchange between the U.S. dollar and non-U.S. dollar currencies affect our results of operations. An increase in the value of a particular currency relative to the U.S. dollar will increase the dollar reporting value for transactions in that particular currency, and a decrease in the value of that currency relative to the U.S. dollar will decrease the dollar reporting value for those transactions.

Since most of our sales are quoted in dollars, and a portion of our expenses, principally salaries and related personnel expenses, are in NIS and Euro, our results may be adversely affected by the appreciation of the NIS and Euro against the U.S. dollar or by a change in the rate of inflation in Israel or if such change in the rate of inflation is not offset, or is offset on a lagging basis, by a corresponding depreciation of the NIS and Euro against the U.S. dollar and other foreign currencies. When the rate of inflation in Israel exceeds the rate of depreciation of the NIS against the dollar, the dollar cost of our operations in Israel increase. If the dollar cost of our operations in Israel increases, our dollar-measured results of operations will be adversely affected.

The following table presents information about the rate of inflation in Israel, the rate of depreciation or appreciation of the NIS against the U.S. dollar, and the rate of inflation of Israel adjusted for the depreciation:

Year ended December 31,	Israeli inflation rate %			NIS depreciation (appreciation) rate %			Israeli inflation adjusted for depreciation (appreciation) %
2006		(0.1	)		(8.2	)		8.1
2007		3.4			(9.0	)		12.4
2008		3.8			(1.1	)		4.9
2009		3.9			(0.7	)		4.6
2010		2.7			(6.0	)		8.7

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

A depreciation of the NIS in relation to the dollar has the effect of reducing the dollar amount of any of our expenses or liabilities which are payable in NIS, unless these expenses or payables are linked to the dollar. This depreciation also has the effect of decreasing the dollar value of any asset which consists of NIS or receivables payable in NIS, unless the receivables are linked to the dollar. Conversely, any increase in the value of the NIS in relation to the dollar has the effect of increasing the dollar value of any unlinked NIS assets and the dollar amounts of any unlinked NIS liabilities and expenses. During 2009 and 2010, the NIS appreciated against the U.S. dollar, which resulted in a significant increase in the U.S. dollar cost of our NIS expenses in such periods. While the NIS/dollar exchange rate was approximately the same at December 31, 2007 and 2008, the NIS fluctuated against the U.S. dollar during 2009 and 2010. Because exchange rates between the NIS and the dollar fluctuate continuously exchange rate fluctuations and especially larger periodic depreciations will have an impact on our profitability and period-to-period comparisons of our results. The effects of foreign currency re-measurements are reported in our consolidated financial statements in current operations.

To manage this risk, from time to time, we have entered into forward exchange contracts to hedge some of our foreign currency exposure. As of December 31, 2010, we had outstanding forward exchange contracts for the acquisition of NIS 89.2 million in consideration for $24.6 million maturing in a period of up to one year from that date. As of December 31, 2010, the changes in fair value of these contracts are $479,000.

Recently Issued Accounting Standards

In October 2009, the FASB issued Accounting Standards Update, or ASU, No. 2009-13, “Multiple-Deliverable Revenue Arrangements (amendments to FASB ASC Topic 605, Revenue Recognition),” or ASU 2009-13, and ASU No. 2009-14, “Certain Arrangements That Include Software Elements (amendments to FASB ASC Topic 985, Software).” ASU 2009-13 requires entities to allocate revenue in an arrangement using estimated selling prices of the delivered goods and services based on a selling price hierarchy. The amendments eliminate the residual method of revenue allocation and require revenue to be allocated using the relative selling price method. ASU 2009-14 removes tangible products from the scope of software revenue guidance and provides guidance on determining whether software deliverables in an arrangement that includes a tangible product are covered by the scope of the software revenue guidance. As a result of the amendments included in ASU 2009-14, many tangible products and services that rely on software will be accounted for under the multiple-element arrangements revenue recognition guidance rather than under the software revenue recognition guidance. ASU 2009-14 also provides guidance on how to allocate transaction consideration when an arrangement contains both deliverables within the scope of software revenue guidance (software deliverables) and deliverables not within the scope of that guidance (non-software deliverables). ASU 2009-13 and ASU 2009-14 are to be applied on a prospective basis for revenue arrangements entered into or materially modified in fiscal years beginning on or after June 15, 2010. We adopted both standards for the fiscal year beginning January 1, 2011. We believe that the adoption of these amendments will not have a material impact on our consolidated financial statements.

In January 2010, the FASB issued ASU No. 2010-06, which amends ASC Topic 820-10, “Fair Value Measurements and Disclosures – Overall,” or ASC 820-10. The update requires a gross presentation of activities within the Level 3 roll-forward and adds a new requirement to disclose transfers in and out of Level 1 and 2 measurements. The update further clarifies the existing disclosure requirements in ASC 820-10 regarding: i) the level of disaggregation of fair value measurements; and ii) the disclosures regarding inputs and valuation techniques. The update was effective for our fiscal year beginning January 1, 2010 except for the gross presentation of the Level 3 roll-forward information, which is effective for our fiscal year beginning January 1, 2011. The principal impact from the update will be expanded disclosures regarding our fair value measurements.

In April 2010, the Emerging Issues Task Force issued ASU 2010-13, an amendment to ASC No. 718 "Compensation - Stock Compensation. The ASU clarifies employee stock options that have exercise prices denominated in the currency of any market in which a substantial portion of the entity's equity securities trade. These should be classified as equity, assuming all other criteria for equity classification are met. The amendments in the ASU do not contain any disclosure requirements incremental to those required by ASC 718. The guidance is effective for our fiscal year beginning January 1, 2011. The adoption of the new guidance will not have a material impact on our consolidated financial statements.

In February 2010, the FASB issued ASU 2010-09, an amendment to certain recognition and disclosure requirements of Subsequent Events codified in ASC 855, "Subsequent Events." The update removes the requirement to disclose the date through which subsequent events were evaluated in both originally issued and reissued financial statements for "SEC Filers." The guidance is effective for our fiscal year ending after June 15, 2010. The adoption of the new guidance did not have a material impact on our consolidated financial statements.

In December 2010, the FASB issued ASU No. 2010-29, which amends ASC Topic 805, “Business Combinations,” or ASC 805. The update requires the disclosure of pro forma information for business combinations. The amendment is effective prospectively for business combinations for which the acquisition date is on or after the beginning of the first annual reporting period beginning on or after December 15, 2010 (early adoption is permitted). The amendment clarifies the acquisition date that should be used for reporting the pro forma financial information disclosures when comparative financial statements are presented. The amendment also improves the usefulness of the pro forma revenue and earnings disclosures by requiring a description of the nature and amount of material, nonrecurring pro forma adjustments that are directly attributable to the business combination. We believe that the adoption of the amendment will not have a material impact on our consolidated financial statements.

B. Liquidity and Capital Resources

From our inception until our initial public offering in March 2000, 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. Since our initial public offering in March 2000, we have satisfied our financial requirements primarily through cash generated by operations, funds generated by our initial public offering (approximately $78.5 million net proceeds) and funds generated from proceeds from option exercises.

In February 2010, we acquired certain assets of Aethra, including certain intellectual property and technology for HD video conferencing endpoint systems. The transaction agreements also include the purchase of additional fixed assets and selected commercial agreements, which remains subject to the approval of the Italian court. The total transaction purchase price will be approximately $10 million (Euro 7.0 million) and we also assumed approximately $4.3 million (Euro 3.0 million) of labor related liabilities. As of December 31, 2010, we have paid $7.0 million in cash and provided a $1.6 million irrevocable bank guarantee. As of such date, we have also recorded $2.7 of acquisition-related restructuring expenses, which represent labor related expenses.

On September 7, 2010, we completed a self tender offer to purchase 5.0% of our voting power, or 976,906 of our ordinary shares, for $7.30 per share, net to the seller in cash, less any required withholding taxes and without interest. We paid an aggregate of approximately $7.13 million for the tendered shares accepted for purchase.

As of December 31, 2010, we had approximately $17.8 million in cash and cash equivalents, $62.7 million in short term investments, and our working capital was approximately $74.7 million. Taking into account long-term investments, we had approximately $116.4 million in cash and investments as of December 31, 2010. We believe that our working capital is sufficient for our present requirements and is sufficient to meet our day to day operating expenses and material commitments for the next 12 months.

Our management believes that another financial measure that is important in assessing our company’s financial condition is day’s sales outstanding, or DSOs. We increased our DSOs from 47 days at December 31, 2009 to 52 days at December 31, 2010.

Capital expenditures for the years ended December 31, 2008, 2009 and 2010 were approximately $3.0 million, $2.1 million and $2.9 million, respectively. These expenditures were principally for research and development equipment and office furniture and equipment. We currently do not have significant capital spending or purchase commitments, but we expect to continue to engage in capital spending consistent with anticipated growth in our operations, infrastructure and personnel.

The following table summarizes our cash flows for the periods presented:

	Year ended December 31,
	2008			2009			2010
	($ in thousands)
Net cash provided by operating activities		5,864			7,256			6,005
Net cash used in investing activities		(2,617	)		(4,711	)		(22,101	)
Net cash used in financing activities		(10,745	)		(128	)		(6,440	)
Net increase (decrease) in cash and cash equivalents		(7,498	)		2,417			(22,536	)
Cash and cash equivalents at beginning of period		45,370			37,872			40,289
Cash and cash equivalents at end of period		37,872			40,289			17,753

Net cash provided by operating activities was approximately $6.0 million for the year ended December 31, 2010. This amount was primarily attributable to our net loss of $3.4 million adjusted for an increase of $5.8 million in accrued expenses and other accounts payable, depreciation and amortization expenses of $4.7 million, stock-based compensation of $2.6 million recorded under ASC 718, an increase of $2.0 million in trade payables and a decrease of $1.3 million in long term prepaid expenses. These adjustments to net loss were off-set in part by a $3.4 million increase in trade receivables, an increase of $1.5 million in inventory, a $1.0 million increase in other accounts receivables and prepaid expenses, a $497,000 tax benefit relating to loss carryforwards arising from the exercise of non-qualified employee stock options, a $365,000 increase in accrued interest, a $136,000 increase in deferred tax asset and a $126,000 decrease in deferred revenues. Net cash provided by operating activities was approximately $7.3 million for the year ended December 31, 2009. This amount was primarily attributable to our net loss of $774,000 adjusted for depreciation and amortization expenses of $3.2 million, stock-based compensation of $4.3 million recorded under ASC 718, an increase in a valuation allowance in the amount of $4.4 million and a decrease of $2.4 million in trade receivables, net. These adjustments to net loss were off-set in part by a decrease of $3.1 million in accrued expenses and other accounts payable, a $1 million increase in other accounts receivables and prepaid expenses, an increase of $1 million in long term prepaid expenses and a $421,000 decrease in accrued interest. Net cash provided by operating activities was approximately $5.9 million for the year ended December 31, 2008. This amount was primarily attributable to net loss of $12.9 million adjusted for depreciation and amortization expenses of $3.9 million, stock-based compensation of $5.4 million recorded under ASC 718, a decrease of $0.5 million in inventory, a $1.5 million increase of deferred revenues, a $0.9 million decrease in trade receivables, a $2.0 million decrease in other receivables and prepaid expenses and a $1.8 million decrease in accrued interest. These adjustments to net income were offset in part by an increase of $0.8 million in deferred tax assets.

Net cash used in investing activities was approximately $22.1 million for the year ended December 31, 2010. Of the cash used in investing activities in the year ended December 31, 2010, approximately $7.0 million was used for the acquisition of Aethra asset, $2.9 million was used for purchases of property and equipment and $12.2 million was used to purchase investments in bank deposits and marketable securities. Net cash used in investing activities was approximately $4.7 million for the year ended December 31, 2009. Of the cash used in investing activities in the year ended December 31, 2009, approximately $2.1 million was used for purchases of property and equipment and approximately $2.6 million was used to purchase investments in bank deposits and marketable securities. Net cash used in investing activities was approximately $2.6 million for the year ended December 31, 2008. Of the cash used in investing activities in the year ended December 31, 2008, approximately $3.0 million was used for purchases of property and equipment, offset by approximately $0.4 million provided by proceeds from investments in bank deposits and marketable securities.

Net cash used in financing activities was approximately $6.4 million for the year ended December 31, 2010. Of the cash used in financing activities in the year ended December 31, 2010, $7.1 million was used to purchase 5% of our voting power in the self tender offer completed in September 2010, offset by a $497,000 tax benefit relating to loss carryforwards arising from the exercise of non-qualified employee stock options and the issuance of $194,000 of ordinary shares and treasury stock upon the exercise of options. Net cash used in financing activities was approximately $128,000 for the year ended December 31, 2009. Of the cash used in financing activities in the year ended December 31, 2009, $1.1 million was used for the repurchase of our company’s shares, offset by a $567,000 tax benefit arising from the exercise of non-qualified employee options and the issuance of $446,000 of ordinary shares and treasury stock. Net cash used in financing activities was approximately $10.7 million for the year ended December 31, 2008. Of the cash used in financing activities in the year ended December 31, 2008, $11.1 million was used for the repurchase of our company’s shares, offset by a $0.4 million tax benefit arising from the exercise of non-qualified employee options.

During the third quarter of 2007, we announced that our Board of Directors had authorized the repurchase of up to $30 million of our ordinary shares in the open market from time to time at prevailing market prices. The repurchase program received the approval of the District Court in Tel Aviv-Jaffa in November 2007 in accordance with the requirements of the Israeli Companies Law. As of December 31, 2010, we had repurchased 3,160,222 ordinary shares under the program at a total purchase price of approximately $23.4 million, or an average price of $7.42 per share. As of December 31, 2010, we had reissued 841,672 of the repurchased ordinary shares in connection with the exercise of employee stock options.

As of December 31, 2010, our principal commitments consisted of obligations outstanding under operating leases. 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. In 2010, we experienced substantial increases in our expenditures as a result of the growth in our operations and personnel. In addition, the dollar cost of our Israeli personnel increased in 2010 as a result of the appreciation of the NIS against the U.S. dollar in such period. We intend to increase our expenditures in the future consistent with our anticipated growth. We anticipate that our cash resources will be used primarily to fund our operating activities, as well as for capital expenditures.

C. Research and Development, Patents and Licenses

We place considerable emphasis on research and development to expand the capabilities of our existing products and technology, to develop new products and to improve our existing technologies and capabilities. We believe that our future success will depend upon our ability to maintain our technological leadership, to enhance our existing products and technology and to introduce on a timely basis new commercially viable products and technology addressing the needs of our customers. Our gross investment in research and development for the years ended December 31, 2008, 2009 and 2010 was $36.9 million, $27 million and $30.9 million, respectively. We intend to continue to devote a significant portion of our personnel and financial resources to research and development. As part of our product development process, we seek to maintain close relationships with our customers to identify market needs and to define appropriate product specifications.

As of December 31, 2010, our research and development staff consisted of approximately 222 employees compared to 199 as of December 31, 2009. In 2010, our research and development activities were conducted mainly at our facilities in Tel Aviv, Israel and in part in Beijing, China and New Hampshire, the United States. In connection with our acquisition of certain assets and liabilities of Aethra in February 2010, we also leased a research and development center in Italy and hired research and development personnel who were previously employed by Aethra. To introduce new, high quality products, we deploy procedures for the design, development and quality assurance of our new product developments. Our team is divided according to our existing product lines. Each product line team is headed by a team leader and includes software or hardware engineers and quality control technicians.

We own six registered U.S. patents relating to various aspects of interactive multimedia communications. During 2010, we filed two new patent applications with the U.S. Patent and Trademark Office covering protocols and techniques to improve multi-media communications. We also filed one patent application in other countries’ patent offices.

D. Trend Information

Revenues increased from $81.0 million for the year ended December 31, 2009 to $95.2 million for the year ended December 31, 2010, an increase of 17.6%. The increase in revenues in 2010 was primarily due to our VBU as a result of an increase in the sales of our infrastructure products and our endpoint product line that we introduced in 2010. We expect that our new endpoint product line will account for a growing percentage of our revenues in the future.

Cisco accounted for approximately 39% and 42% of our sales for the years ended December 31, 2008 and 2009, respectively. In April 2010, Cisco completed the acquisition of TANDBERG, one of our principal competitors. As a result of the acquisition, Cisco sales declined to 34% of sales in 2010 and we expect Cisco sales to decline significantly in 2011.

For additional trend information see the discussion in Item 5.A “Operating Results and Financial Review and Prospects – Operating Results.”

All officers and directors as a group (7 persons)		$	592,062			$	85,020

We provide automobiles or automobile expense reimbursement to our executive officers at our expense.

As of December 31, 2010, our directors and executive officers as a group, consisting of seven persons, held options to purchase an aggregate of 946,287 ordinary shares, having exercise prices ranging from $4.7 to $20.17. The options granted to our executive officers and directors generally vest over a four-year period. Since our 2009 annual general meeting options granted to our directors are fully vested at the date of grant. The options will expire between June 28, 2011 and November 17, 2016 (which is six to ten years from the date of grant of the respective options) or earlier upon termination of employment as an executive officer or with respect to a director, within 18 months after termination or resignation from such office. All of such options were granted under our 2000 Stock Option Plan. See this Item 6E. “Directors, Senior Management and Employees - Share Ownership - Stock Option Plan.”

We pay each of our outside directors the minimum statutory annual and per meeting cash attendance fees payable to outside directors in companies of our size established in the Israeli Companies Regulations (Rules Regarding Compensation and Expenses to Outside Directors), 2000, as amended (currently, NIS 45,000 ($12,680) per year and NIS 1,590 ($448) per meeting attended), in accordance with the approval of our shareholder at our 2008 annual general meeting.

In addition, at our 2009 annual general meeting, our shareholders approved an equity-based compensation plan for directors (other than the current Chairman of our Board of Directors), as follows: (i) for each year of service as a director, an annual grant of options to purchase 10,000 ordinary shares to each of the directors (including outside directors), other than any outside director who is determined by the Board of Directors to be an “expert outside director,” as defined in regulations promulgated under the Israeli Companies Law and (ii) for each year of service as an outside director who is determined by our Board of Directors to be an “expert outside director,” an annual grant of options to purchase 13,300 ordinary shares. Our Board of Directors determined that Mr. Atsmon qualifies as an “expert outside director.” All of the options will be granted under our 2000 Employee Stock Option Plan, will be fully vested and immediately exercisable on the applicable date of grant and will expire 18 months after such director’s termination or resignation from office. The exercise price per share of the options will be equal to the closing price per share of the ordinary shares on the NASDAQ Global Select Market on the applicable date of grant. The term of the compensation plan is for six years commencing from the date of the annual general meeting and will be extended, with respect to any current or future director who is reelected or elected, as applicable, during such six-year period, for the duration of his or her then pending three-year term.

At our 2009 annual general meeting, our shareholders also approved an equity-based compensation plan for the Chairman of our Board of Directors. In accordance with such plan, following his reelection at our 2010 annual general meeting, options to purchase 20,000 ordinary shares were granted to our Chairman on the date of such meeting, and thereafter, will be granted annually during the three-year period of the Chairman’s term, on the date of each annual general meeting (i.e., on the date of the 2011 and 2012 annual general meetings). Our Chairman would be entitled to receive, if reelected, options to purchase 60,000 ordinary shares during any three-year term going forward. This same mechanism would apply at the time of the Chairman’s reelection at the 2013 annual general meeting, so that our Chairman would be entitled to receive options to purchase an aggregate of 120,000 ordinary shares during the next six years, if reelected. The term of the Chairman’s benefit plan is for six years. The options will be fully vested and exercisable immediately on the applicable date of grant and will expire 18 months after the Chairman’s termination of or resignation from office. The options are granted under our 2000 Employee Stock Option Plan. The exercise price per share of the options will be equal to the closing price per share of our ordinary shares on the NASDAQ Global Select Market on the applicable date of grant.

Pursuant to NASDAQ Listing Rules, compensation of our chief executive officer and other executive officers (as set forth in such rules) is recommended to our Board of Directors for determination by a majority of our independent directors, subject to any further approvals required under the Israeli Companies Law. See Item 6C. “Directors, Senior Management and Employees - Board Practices - Approval of Related Party Transactions Under Israeli Law.”

C. Board Practices

Election of Directors

Our Articles of Association provide for a board of directors consisting of no less than five and no more than nine members or such other number as may be determined from time to time at a general meeting of shareholders. Our Board of Directors is currently composed of five directors.

In accordance with our Articles of Association, our Board of Directors is divided into three classes (other than outside directors), each consisting of a number of directors equal as nearly as practicable to one-third of the total number of non-outside directors. Generally, at each annual meeting of shareholders one class of directors is elected for a term of three years by a vote of the holders of a majority of the voting power represented and voting at such meeting. Under our Articles of Association, a vacancy in two of the three director classes at any given time is permitted. Our Class A and Class B director categories are currently vacant.

All the members of our Board of Directors, except the outside directors (as detailed below) may be reelected upon completion of their term of office. In the intervals between annual general meetings of the company, our Board of Directors may elect new directors, whether to fill vacancies or in addition to those of their body, provided that the total number of directors will not at any time exceed any maximum number, if any, fixed by or in accordance with our Articles of Association.

Our directors are nominated by a majority of our independent directors, as such term is defined under NASDAQ Listing Rules.

Outside and Independent Directors

Outside Directors. The Israeli Companies Law requires Israeli companies with shares that have been offered to the public in or outside of Israel to appoint at least two outside directors. No person may be appointed as an outside director if the person or the person’s relative, partner, employer or any entity under the person’s control, has or had, on or within the two years preceding the date of the person’s appointment to serve as outside director, any affiliation with the company or any entity controlling, controlled by or under common control with the company. The term “affiliation” includes:

an employment relationship;

a business or professional relationship maintained on a regular basis;

control; and

service as an office holder.

In addition, no person may serve as an outside director if the person’s position or other activities create, or may create a conflict of interest with the person’s responsibilities as an outside director or may otherwise interfere with the person’s ability to serve as an outside director. If, at the time an outside director is to be appointed, all current members of the board of directors are of the same gender, then at least one outside director must be of the other gender.

A person is qualified to serve as an outside director only if he or she has “accounting and financial expertise” or “professional qualifications,” as such terms are defined under regulations promulgated under the Israeli Companies Law. At least one outside director must have “accounting and financial expertise.” However, Israeli companies listed on certain stock exchanges outside Israel, including The NASDAQ Global Select Market, such as our company, are not required to appoint an outside director with “accounting and financial expertise” if a director with accounting and financial expertise who qualifies as an independent director for purposes of audit committee membership under the laws of the foreign country in which the stock exchange is located serves on its board of directors. All of the outside directors of such a company must have “professional qualifications.”

Any committee of the board of directors that is authorized to exercise powers vested in the board of directors must include at least one outside director and the audit committee must include all of the outside directors. An outside director is entitled to compensation as provided in regulations adopted under the Israeli Companies Law and is otherwise prohibited from receiving any other compensation, directly or indirectly, in connection with such service.

Outside directors are elected by a majority vote at a shareholders’ meeting, provided that either:

the majority of shares voted at the meeting in favor of their election include at least one-third of the shares held by non-controlling shareholders that voted at the meeting (not including abstentions); or

the total number of shares held by non-controlling shareholders voted against the election of the outside director does not exceed one percent of the aggregate voting rights in the company.

The initial term of an outside director is three years and may be extended for an additional three years. However, Israeli companies listed on certain stock exchanges outside Israel, including the NASDAQ Global Select Market, such as our company, may appoint an outside director for additional terms of not more than three years subject to certain conditions. Such conditions include the determination by the audit committee and board of directors, that in view of the director’s professional expertise and special contribution to the company’s board of directors and its committees, the appointment of the outside director for an additional term is in the best interest of the company. Outside directors may be removed from office only by the same percentage of shareholders as is required for their election, or by a court, and then only if the outside directors cease to meet the statutory qualifications for their appointment or if they violate their duty of loyalty to the company.

Our Board of Directors has three outside directors under Israeli law. Mr. Joseph Atsmon and Ms. Liora Lev, both of whom have “accounting and financial expertise,” and Dr. Yoseph Linde, who has “professional expertise,” as such terms are defined under the Israeli Companies Law. Mr. Atsmon was elected to serve as an outside director for an initial three year term in 2003, was elected to serve as an outside director for a second three-year term at our 2006 annual general meeting of shareholders and was elected to serve as an outside director for an additional three-year term at our 2009 annual general meeting of shareholders. Ms. Lev was elected to serve as an outside director for an initial three year term at our 2006 annual general meeting of shareholders and was elected to serve as an outside director for a second three-year term at our 2009 annual general meeting of shareholders. Dr. Yoseph Linde was elected to serve as an outside director for an initial three year term at our 2008 annual general meeting of shareholders.

Independent Directors. In general, NASDAQ Listing Rules require that the board of directors of a NASDAQ-listed company have a majority of independent directors and its audit committee must have at least three members and be comprised only of independent directors, each of whom satisfies the respective “independence” requirements of NASDAQ and the Securities and Exchange Commission.

Pursuant to a recent amendment to the Israeli Companies Law, an Israeli company whose shares are publicly traded may elect to adopt a provision in its articles of association pursuant to which a majority of its board of directors will constitute individuals complying with certain independence criteria prescribed by the Israeli Companies Law. We have not included such a provision in our Articles of Association since our board of directors complies with the independent director requirements of the NASDAQ Listing Rules described above.

Independent directors of our company meet at least twice a year in an executive session. Among other things, at such sessions the independent directors recommend the compensation of all our senior officers and nominate directors to be elected by our shareholders at our annual general meeting. Our executive officers do not participate in any discussions or decisions that involve any aspect of their compensation.

Our Board of Directors has determined that each of Ms. Lev and Messrs. Atsmon and Linde qualifies as an independent director under the requirements of the Securities and Exchange Commission and NASDAQ. Ms. Lev and Messrs. Atsmon and Linde are also our outside directors within the meaning of the Israeli Companies Law.

Committees of the Board of Directors

Audit Committee. Our Audit Committee, established in accordance with Section 114 of the Israeli Companies Law and Section 3(a)(58)(A) of the Securities Exchange Act of 1934, assists our Board of Directors in overseeing the accounting and financial reporting processes of our company and audits of our financial statements, including the integrity of our financial statements, compliance with legal and regulatory requirements, our independent public accountants’ qualifications and independence, the performance of our internal audit function and independent public accountants, finding any defects in the business management of our company for which purpose the Audit Committee may consult with our independent auditors and internal auditor, proposing to the board of directors ways to correct such defects, and such other duties as may be directed by our Board of Directors. The responsibilities of the Audit Committee also include approving related-party transactions as required by Israeli law. Under Israeli law, an audit committee may not approve an action or a transaction with a controlling shareholder, or with an office holder, unless at the time of approval two outside directors are serving as members of the audit committee and at least one of the outside directors was present at the meeting in which an approval was granted.

Our Audit Committee is authorized generally to investigate any matter within the scope of its responsibilities and has the power to obtain from the internal auditing unit, our independent auditors or any other officer or employee any information that is relevant to such investigations. Our Audit Committee also has the right to hire independent counsel and accountants to assist it in any investigation that it may instigate.

Our Audit Committee also serves as our Financial Statement Review Committee, as defined in regulations promulgated under the Israeli Companies Law recently enacted and applicable to the review process of financial statements commencing from the 2010 year-end financial statements.

Our Audit Committee consists of three members of our Board of Directors who satisfy the respective “independence” requirements of the Securities and Exchange Commission, NASDAQ and Israeli law for audit committee members. Our Audit Committee is currently composed of Joseph Atsmon, Liora Lev and Yoseph Linde. Joseph Atsmon has been elected as the Chairperson of the Audit Committee. The Audit Committee meets at least once each quarter. Our Audit Committee charter is available on our website at www.radvision.com.

Option Committee. Our Board of Directors has established an option committee, which administers our option plans (see Item 6E. Directors, Senior Management and Employees - Share Ownership - Stock Option Plan”). The Option Committee is responsible for approving all option grants other than grants to our directors, chief executive officer and all other officers that report to the chief executive officer. Messrs. Zohar Zisapel and Joseph Atsmon are the current members of our Option Committee.

Compensation Committee. Our Board of Directors has established a compensation committee, which is responsible for the hiring and compensation of all employees that report to the chief executive officer of our company, subject to any other approvals that may be required under applicable law. Messrs. Zohar Zisapel and Joseph Atsmon are the current members of our Compensation Committee.

Internal Audit

The Israeli Companies Law requires the board of directors of a public company to appoint an internal auditor nominated by the audit committee. The role of the internal auditor is to examine, among other things, the compliance of the company’s conduct with applicable law and orderly business practice. A person who does not satisfy the Israeli Companies Law’s independence requirements may not be appointed as an internal auditor. Our internal auditor is currently Mr. Ilan Chaikin, Certified Public Accountant, at Chaikin, Cohen, Rubin and Duvshani.

Directors’ Service Contracts

We do not have any service contracts with our directors. There are no arrangements or understandings between us and any of our subsidiaries, on the one hand, and any of our directors, on the other hand, providing for benefits upon termination of their employment or service as directors of our company or any of our subsidiaries.

Approval of Related Party Transactions Under Israeli Law

Fiduciary Duties of Office Holders

The Israeli Companies Law codifies the fiduciary duties that “office holders,” including directors and executive officers, owe to a company. An “office holder” is defined in the Israeli Companies Law as a director, general manager, chief business manager, deputy general manager, vice general manager, other manager directly subordinate to the general manager or any other person assuming the responsibilities of any of the foregoing positions without regard to such person’s title. An office holder’s fiduciary duties consist of a duty of care and a duty of loyalty. The duty of care requires an office holder to act at a level of care that a reasonable office holder in the same position would employ under the same circumstances. This includes the duty to utilize reasonable means to obtain (i) information regarding the appropriateness of a given action brought for his approval or performed by him by virtue of his position and (ii) all other information of importance pertaining to the foregoing actions. The duty of loyalty includes (i) avoiding any conflict of interest between the office holder’s position in the company and any other position he holds or his personal affairs, (ii) avoiding any competition with the company’s business, (iii) avoiding exploiting any business opportunity of the company in order to receive personal gain for the office holder or others, and (iv) disclosing to the company any information or documents relating to the company’s affairs that the office holder has received due to his position as an office holder. Each person identified as a director or executive officer in the first table under Item 6.A. “Directors, Senior Management and Employees — Directors and Senior Management” above is an office holder.

The Israeli Companies Law requires that an office holder promptly, and no later than the first board meeting at which such transaction is considered, disclose any personal interest that he or she may have and all related material information known to him or her and any documents in their possession, in connection with any existing or proposed transaction by us. In addition, if the transaction is an extraordinary transaction, that is, a transaction other than in the ordinary course of business, other than on market terms, or likely to have a material impact on the company’s profitability, assets or liabilities, the office holder must also disclose any personal interest held by the office holder’s spouse, siblings, parents, grandparents, descendants, spouse’s descendants and the spouses of any of the foregoing, or by any corporation in which the office holder or a relative is a 5% or greater shareholder, director or general manager or in which he or she has the right to appoint at least one director or the general manager.

Approval of Transactions with Office Holders

Under the Israeli Companies Law and our Articles of Association, all arrangements as to compensation of office holders who are not directors require approval of our Audit Committee and Board of Directors if the transaction is an “extraordinary transaction” or relates to exculpation, insurance or indemnification of an office holder, and if such transaction is not an “extraordinary transaction,” the approval of our General Manager according to guidelines of the Board of Directors. The compensation of office holders who are directors must be approved by our Audit Committee, Board of Directors and shareholders.

Some transactions, actions and arrangements involving an office holder (or a third party in which an office holder has an interest) must be approved by the board of directors or as otherwise provided for in a company’s articles of association, however, a transaction that is adverse to the company’s interest may not be approved. In some cases, such a transaction must be approved by the audit committee and by the board of directors itself, and under certain circumstances shareholder approval may be required. A director who has a personal interest in a transaction that is considered at a meeting of the board of directors or the audit committee may not be present during the board of directors or audit committee discussions and may not vote on the transaction, unless the transaction is not an extraordinary transaction or the majority of the members of the board or the audit committee have a personal interest, as the case may be. In the event the majority of the members of the board of directors or the audit committee have a personal interest, then the approval of the general meeting of shareholders is also required.

Disclosure of Personal Interests of a Controlling Shareholder; Approval of Transactions with Controlling Shareholders

The disclosure requirements that apply to an office holder also apply to such transaction with respect to his or her personal interest in the transaction. The Israeli Companies Law provides that an extraordinary transaction with a controlling shareholder or an extraordinary transaction with another person in whom the controlling shareholder has a personal interest or a transaction with a controlling shareholder or his relative regarding terms of service and employment, must be approved by the audit committee, the board of directors and shareholders. The shareholder approval for such a transaction must include at least one-third of the shareholders who have no personal interest in the transaction who voted on the matter (not including abstentions). The transaction can be approved by shareholders without this one-third approval if the total holdings of those shareholders who have no personal interest and voted against the transaction do not represent more than one percent of the voting rights in the company.

Under the Companies Regulations (Relief from Related Party Transactions), 5760-2000, promulgated under the Israeli Companies Law, as amended, certain extraordinary transactions between a public company and its controlling shareholder(s) do not require shareholder approval. Such extraordinary transactions must be approved by both the audit committee and board of directors. In addition, under such regulations, directors’ compensation and employment arrangements in a public company do not require the approval of the shareholders if both the audit committee and the board of directors agree that such arrangements are solely for the benefit of the company. Also, employment and compensation arrangements for an office holder that is a controlling shareholder of a public company do not require shareholder approval if certain criteria are met. The foregoing exemptions from shareholder approval will not apply if one or more shareholders holding at least 1% of the issued and outstanding share capital of the company or of the company’s voting rights, objects to the use of these exemptions provided that such objection is submitted to the company in writing not later than fourteen days from the date of the filing of a report regarding the adoption of such resolution by the company pursuant to the requirements of the Israeli Securities Law. If such objection is duly and timely submitted, then the transaction or compensation arrangement of the directors will require shareholders’ approval as detailed above.

In addition, a private placement of securities that will (i) cause a person to become a controlling shareholder or (ii) increase the relative holdings of a shareholder that holds 5% or more of the company’s outstanding share capital, or (iii) will cause any person to become, as a result of the issuance, a holder of more than 5% of the company’s outstanding share capital in a private placement in which 20% or more of the company’s outstanding share capital prior to the placement are offered, the payment for which (in whole or in part) is not in cash nor under market terms, requires approval by the board of directors and the shareholders of the company. Other than as described, under Israeli law private placements require the approval of the board of directors.

The Israeli Companies Law provides that an acquisition of shares in a public company must be made by means of a tender offer if as a result of the acquisition the purchaser would become a 25% or greater shareholder of the company. This rule does not apply if there is already another 25% or greater shareholder of the company. Similarly, the Israeli Companies Law provides that an acquisition of shares in a public company must be made by means of a tender offer if as a result of the acquisition the purchaser would hold greater than a 45% interest in the company, unless there is another shareholder holding more than a 45% interest in the company. These requirements do not apply if, in general, the acquisition was made in a private placement that received shareholder approval, (i) was from a 25% or greater shareholder of the company which resulted in the acquirer becoming a 25% or greater shareholder of the company, if there is not already a 25% or greater shareholder of the company, or (ii) was from a shareholder holding a 45% interest in the company which resulted in the acquirer becoming a holder of a 45% interest in the company if there is not already a 45% or greater shareholder of the company.

If, as a result of an acquisition of shares, the acquirer will hold more than 90% of a public company’s outstanding shares or a class of shares, the acquisition must be made by means of a tender offer for all of the outstanding shares or a class of shares. If less than 5% of the outstanding shares are not tendered in the tender offer, all the shares that the acquirer offered to purchase will be transferred to the acquirer. The Israeli Companies Law provides for appraisal rights if any shareholder files a request with the court within three months following the consummation of a full tender offer. If more than 5% of the outstanding shares are not tendered in the tender offer, then the acquirer may not acquire shares in the tender offer that will cause his shareholding to exceed 90% of the outstanding shares.

Exculpation, Indemnification and Insurance of Directors and Officers

Exculpation of Office Holders

The Israeli Companies Law provides that an Israeli company cannot exculpate an office holder from liability with respect to a breach of his or her duty of loyalty. If permitted by its articles of association, a company may exculpate in advance an office holder from his or her liability to the company, in whole or in part, with respect to a breach of his or her duty of care. However, a company may not exculpate in advance a director from his or her liability to the company with respect to a breach of his duty of care concerning a distribution, as such term is defined under the Israeli Companies Law.

Insurance of Office Holders

The Israeli Companies Law provides that a company may, if permitted by its articles of association, enter into a contract to insure office holders in respect of liabilities incurred by the office holder with a respect to an act or omission performed in his or her capacity as an office holder, as a result of:

a breach of the office holder’s duty of care to the company or to another person;

a breach of the office holder’s duty of loyalty to the company, provided that the office holder acted in good faith and had reasonable cause to assume that his or her act would not prejudice the company’s interests; or

a financial liability imposed upon the office holder in favor of another person.

Indemnification of Office Holders

The Israeli Companies Law provides that a company may, if permitted by its articles of association, indemnify an office holder for acts or omissions performed by the office holder in such capacity for:

a monetary liability imposed on the office holder in favor of another person by any judgment, including a settlement or an arbitrator’s award approved by a court;

reasonable legal expenses, including attorney’s fees, actually incurred by the office holder as a result of an investigation or proceeding instituted against him or her by a competent authority, provided that such investigation or proceeding concluded without the filing of an indictment against the office holder or the imposition of any monetary liability in lieu of criminal proceedings, or concluded without the filing of an indictment against the office holder and a monetary liability was imposed on the officer holder in lieu of criminal proceedings with respect to a criminal offense that does not require proof of criminal intent; and

reasonable legal expenses, including attorneys’ fees, incurred by the office holder or which were imposed on him or her by a court, in an action instituted by the company or on the company’s behalf or by another person, against the office holder, or in a criminal charge from which he was acquitted, or in a criminal proceeding in which the office holder was convicted of a criminal offense which does not require proof of criminal intent.

In accordance with the Israeli Companies Law, a company’s articles of association may permit the company to:

prospectively undertake to indemnify an office holder, except that with respect to a monetary liability imposed on the office holder by any judgment, settlement or court-approved arbitration award, the undertaking must be limited to types of events which the company’s board of directors deems foreseeable considering the company’s actual operations at the time of the undertaking, and to an amount or standard that the board of directors has determined as reasonable under the circumstances; and

retroactively indemnify an office holder of the company.

Limitations on Exculpation, Insurance and Indemnification

The Israeli Companies Law provides that neither a provision of the articles of association permitting the company to enter into a contract to insure the liability of an office holder, nor a provision in the articles of association or a resolution of the board of directors permitting the indemnification of an office holder, nor a provision in the articles of association exculpating an office holder from duty to the company shall be valid, where such insurance, indemnification or exculpation relates to any of the following:

a breach by the office holder of his duty of loyalty unless, with respect to insurance coverage or indemnification, the office holder acted in good faith and had a reasonable basis to believe that the act would not prejudice the company;

a breach by the office holder of his duty of care if such breach was committed intentionally or recklessly, unless the breach was committed only negligently;

any act or omission done with the intent to unlawfully yield a personal gain; or

any fine or forfeiture imposed on the office holder.

Pursuant to the Israeli Companies Law, exculpation of, procurement of insurance coverage for, and an undertaking to indemnify or indemnification of, our office holders must be approved by our Audit Committee and our Board of Directors and, if the office holder is a director, also by our shareholders.

Our Articles of Association allow us to insure, indemnify and exempt our office holders to the fullest extent permitted by law, subject to the provisions of the Israeli Companies Law. On January 18, 2000, our shareholders agreed to indemnify our office holders to the fullest extent permitted under the Israeli Companies Law. At our 2007 annual general meeting of shareholders, our shareholders approved a new form of indemnification agreement, which indemnifies the office holders to the fullest extent permitted under the Israeli Companies Law as currently in effect. We have obtained directors and officers liability insurance for the benefit of our office holders.

Recent Amendment to the Israeli Companies Law

In March 2011, the Israeli Parliament adopted Amendment No. 16 to the Israeli Companies Law, or Amendment No. 16, which implements a comprehensive reform in corporate governance in Israel. Most of the provisions of Amendment No. 16 will become effective on May 15, 2011 and the remainder will become effective on September 15, 2011. A summary of the principal changes introduced by Amendment No. 16 is set forth below:

A higher shareholder approval threshold will need to be attained to permit a chief executive officer to also serve as chairman of the board and vice versa. In addition, the chairman will not have the ability to serve the company in any capacity other than as the chief executive officer;

The majority of the members of the audit committee will be required to be “independent” (as such term is defined under the Israeli Companies Law)and the chairman of the audit committee will be required to be an outside director. In addition, the following persons will be disqualified from serving as members of the audit committee: the chairman, any director employed by the company or by its controlling shareholder or by an entity controlled by the controlling shareholder, a director who regularly provides services to the company or to its controlling shareholder or to an entity controlled by the controlling shareholder, and any director who derives most of its income from the controlling shareholder;

The functions to be performed by the audit committee will be expanded to include, among others, the following: determination whether certain related party actions and transactions are “material” or “extraordinary” for the purposes of the requisite approval procedures, to assess the scope of work and compensation of the company’s independent accountant, to assess the company’s internal audit system and the performance of its internal auditor, and to set whistle blower procedures (including protections afforded to whistle blowers);

The threshold to elect outside directors will be increased, such that the election of outside directors will require a majority vote at a shareholders’ meeting, provided that either: (1) at least a majority (previously, one-third) of the shares of non-controlling shareholders voted at the meeting on the matter vote in favor of the election of the outsider director, or (2) the total number of shares of non-controlling shareholders voted against the election of the outside director does not exceed 2% (previously, 1%) of the voting rights in the company;

The independence requirements of outside directors will be enhanced such that an individual may not be appointed as an outside director: (1) in a company that does not have a 25% shareholder, if he has an affiliation (as such term is defined in the Israeli Companies Law) with any person, at the time of his appointment, who is the chairman, the chief executive officer, a 5% shareholder or the chief financial officer, or (2) if he or his relative, partner, employer, supervisor or an entity he controls has other than negligible business or professional relations with any of the persons with whom he may not be affiliated;

Outside directors will be able to be re-elected for up to two (previously, one) additional three-year terms. Reelection of an external director will be effected through one of the following mechanisms: (i) the board of directors proposed the nominee and his appointment was approved by the shareholders in the manner required to appoint outside directors for their initial term (which was the only available way to re-elect external directors prior to the adoption of Amendment No. 16), or (ii) a shareholder holding 1% or more of the voting rights proposed the reelection of the nominee, and the nominee is approved by a majority of the votes cast by the shareholders of the company on the matter who are not the controlling shareholders and those who have a personal interest in the matter as a result of their relationship with any controlling shareholder, provided that the aggregate votes cast by such non-excluded shareholders in favor of the reelection constitute more than 2% of the voting rights in the company;

The terms of employment of an officer will now require the approval of the audit committee as well as the board of directors;

The threshold to approve extraordinary transactions with a controlling shareholder or in which a controlling shareholder has a personal interest will be increased, such that: (i) at least a majority (previously one-third) of the votes cast by shareholders who have no personal interest in the transaction are voted in favor of the transaction, or (ii) the votes cast by shareholders who have no personal interest in the transaction against the transaction do not represent more than 2% (previously 1%) of the voting rights in the company. In addition, any such extraordinary transaction whose term is more than three years will require approval every three years, unless (with respect to transactions not involving management fees or employment terms) the audit committee approves that a longer term is reasonable under the circumstances; and

With respect to full tender offers (tender offers for the acquisition of all outstanding shares in a company), the time-frame for a shareholder to a request appraisal rights with respect to the tender offer will be extended from three to six months following the consummation of a tender, but the acquirer will be permitted to stipulate that tendering shareholders forfeit their appraisal rights.

D. Employees

We reduced the number of our employees during the latter part of 2008 and early 2009 as part of our cost-cutting initiatives. The number of our employees increased in 2010 primarily due to our engagement of personnel who were previously employed by Aethra. As of December 31, 2010, we had 429 employees.

The following table presents the number of our employees categorized by activity as of December 31:

	As of December 31,
	2008		2009		2010
Research and development		230		199		222
Sales and marketing		133		127		139
Operations and customer support		48		35		36
Management and administration		31		32		32
Total		442		393		429

The following table presents the number of our employees categorized by geographic location as of December 31:

	As of December 31,
	2008		2009		2010
Israel		248		226		224
Americas		95		74		66
Asia-Pacific		81		71		74
Europe		18		22		65
Total		442		393		429

Our relationships with our employees in Israel are governed by Israeli labor legislation and regulations, extension orders of the Israeli Ministry of Labor and personal employment agreements. Israeli labor laws and regulations are applicable to all of our employees in Israel. The laws concern various matters, including severance pay rights at termination, notice period for termination, retirement or death, length of workday and workweek, minimum wage, overtime payments and insurance for work-related accidents. We currently make contributions towards funding our ongoing contingent legal severance pay obligations by paying monthly premiums for our employees’ insurance policies and/or pension funds on account of such severance obligations.

In addition, Israeli law requires Israeli employees and employers to pay specified sums to the National Insurance Institute, which is similar to the United States Social Security Administration. Since January 1, 1995, such amounts also include payments for national health insurance. The payments to the National Insurance Institute that include health insurance fees are approximately 17.43% of wages, of which the employee contributes approximately 69.0% and the employer contributes approximately 31.0%. The majority of our permanent employees are covered by life and pension insurance policies providing customary benefits to employees, including retirement and severance benefits. We contribute 13.3% to 15.8%, depending on the employee, of base wages to such plans and the employee contributes about 5.0%. We and our employees are not parties to any collective bargaining agreements. However, certain provisions of the collective bargaining agreements between the Histadrut, the General Federation of Labor in Israel, and the Coordination Bureau of Economic Organizations, including the Manufacturers’ Association of Israel, are applicable to our employees by “extension orders” of the Israeli Ministry of Labor. These provisions principally concern periodic cost of living adjustments, travel allowances, recuperation pay and other conditions of employment.

At the start of their employment, our employees in Israel generally sign written employment agreements that include confidentiality and non-compete provisions. At the start of their employment, our employees in North America generally sign offer letters specifying basic terms and conditions of employment as well as non-disclosure agreements.

In connection with the Aethra asset acquisition, we are required under Italian law to pay certain expenses relating to former employees of the Aethra video department who are currently subject to the Italian CIGS unemployment plan. The agreement entered into with the seller provides, among other things, that the 150 employees who were previously part of Aethra’s video department will become subject to the Italian CIGS unemployment plan. CIGS permits companies experiencing financial difficulties to temporarily suspend the employment of employees without having to pay their respective salaries and the suspended employees are entitled to unemployment benefits from the Italian government. In addition, we are required to pay monthly social security payments and severance payments. As of the date of this annual report, approximately 33% of Aethra’s video department employees have been recalled to employment duty and have been hired by our Italian subsidiary RADVISION Italy S.r.l, while other employees continue to be suspended from work and receive benefits under the CIGS plan.

In accordance with Italian law, the application to approve the original “crisis” under CIGS was filed with the authorities for a period of 12 months and expired on February 9, 2011. On January 24, 2011, we formally commenced a collective voluntary dismissal procedure ("Mobilità") in order to dismiss the employees currently subject to the CIGS plan, commencing February 10, 2011, which was agreed to by the Trade Union. Pursuant to an agreement with the Trade Union executed on January 26, 2011, we have filed an application for a further 12 months of CIGS for reorganization for all employees who do not adhere to the Mobilità, however, if the application is refused by the authorities, we will dismiss all of the employees that we do not intend to employ and will pay them advance notice payments and a mandatory indemnity payment.

Subject to currently exercisable options with exercise prices ranging between $4.70 and $20.17 and expiration dates ranging between June 28, 2011 and March 12, 2016.

Stock Option Plan

In 2000, we adopted our 2000 Employee Stock Option Plan, or the 2000 Plan, which authorizes the grant of options to employees and consultants of our company and its subsidiaries. The 2000 Plan initially authorized the issuance thereunder of up to 636,477 ordinary shares and, in addition, subject to sufficient authorized share capital, provides for the reservation of up to 4% of our share capital, on a fully diluted basis, in each subsequent year following the year 2000. We are currently authorized to issue up to 7,996,316 ordinary shares under the 2000 Plan.

Type of Options. Awards under the 2000 Plan may be granted pursuant to Section 102 of the Israeli Income Tax Ordinance [New Version], 1961, or the Israeli Tax Ordinance, Section 3.(9) of the Israeli Tax Ordinance, and may also be granted in the form of incentive stock options, as provided in Section 422 of the U.S. Internal Revenue Code of 1986, as amended, and non-qualified stock options.

Plan Administration. The Option Committee appointed by the Board of Directors administers the 2000 Plan, subject to the ratification of the Board of Directors. Subject to the provisions of the 2000 Plan and applicable law, the Option Committee has the authority to recommend to the Board of Directors:

the persons to whom awards are granted;

the form, terms and conditions of the written stock option agreement evidencing the option, including the type of option and the number of shares to which it pertains, the exercise price, option term, vesting schedule and exercisability of the option in special cases (such as death, retirement, disability and change of control); and

the form and provisions of the notice of exercise and payment upon exercise of the option.

Subject to the provisions of the 2000 Plan and law, the Board of Directors has the authority to:

nominate a trustee for options issued under Section 102 of the Israeli Tax Ordinance;

adjust any or all of the number and type of shares that thereafter may be made the subject of options, the number and type of shares subject to outstanding options, and the grant or exercise price with respect to any option, or, if deemed appropriate, make provision for a cash payment to the holder of any outstanding option in order to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the 2000 Plan in the event of any dividend or other distribution, recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split-up, spin-off, combination, repurchase, or exchange of shares or other securities;

interpret the provisions of the 2000 Plan; and

prescribe, amend, and rescind rules and regulations relating to the 2000 Plan or any award there under as it may deem necessary or advisable.

Option Price. The option price per share may not be less than 100% of the fair market value (as such term is defined in the 2000 Plan) of such share on the date of the award; provided, however, that in the case of an award of an incentive stock option made to a 10% owner (as such term is defined in the 2000 Plan), the option price per share may not be less than 110% of the fair market value of such share on the date of the award.

Option Period. An option may not be exercisable after the expiration of ten years from the date of its award, and in the case of an award of incentive stock options made to a 10% owner, such options may not be exercisable after the expiration of five years from its date of award. No option may be exercised after the expiration of its term. In 2006, the Board of Directors resolved to reduce the option period of future grants to employees to six years.

Non-Transferability of Options. Options granted under the 2000 Plan are not assignable or transferable by the optionee, other than by will or the laws of descent and distribution, and may be exercised during the lifetime of the optionee only by the optionee or his or her guardian or legal representative. However, during the optionee’s lifetime, the optionee may, with the consent of the Option Committee, transfer without consideration all or any portion of his options to members of the optionee’s immediate family (as defined in the 2000 Plan), a trust established for the exclusive benefit of members of the optionee’s immediate family, or a limited liability company in which all members are members of the optionee’s immediate family.

Amendment and Termination. Except as set forth in the 2000 Plan, neither the Board of Directors nor the Option Committee may, without the consent of the optionee, alter or in any way impair the rights of such optionee under any award previously granted. Neither the termination of the 2000 Plan nor the change of control of our company, except to the extent provided in the 2000 Plan, will affect any option previously granted.

A summary of the status of the 2000 Plan as of December 31, 2008, 2009 and 2010, and changes during the years ended on those dates, is presented below:

On November 25, 2008, we commenced a tender offer to eligible employees (other than our directors, chief executive officer, chief financial officer, president and senior officers who report to the chief executive officer) to exchange outstanding options to purchase ordinary shares issued under our 2000 Plan having an exercise price of $7.50 or more per share, for replacement options issued under our 2000 Plan that entitle the holder to purchase the same number of our ordinary shares at an exercise price equal to the greater of (i) $7.50 per share and (ii) the per share closing price of our ordinary shares on the NASDAQ Global Select Market on the date the replacements options are granted. Pursuant to the exchange offer that expired on December 24, 2008, we accepted for exchange eligible options to purchase an aggregate of 1,276,950 ordinary shares that had been granted under the 2000 Plan and granted new options to purchase an aggregate of 1,276,950 ordinary shares, under the 2000 Plan. The new options have an exercise price equal to $7.5 and have a vesting schedule as described in the tender offer documents.

Major Shareholders Voting Rights

The voting rights of our major shareholders do not differ from the voting rights of other holders of our ordinary shares.

These numbers are not representative of the number of beneficial holders of our shares nor are they representative of where such beneficial holders reside, since many of these ordinary shares were held of record by banks, brokers or other nominees (including one U.S. nominee company, CEDE & Co., which held approximately 77.7% of our outstanding ordinary shares as of such date).

ITEM 8. FINANCIAL INFORMATION

A. Consolidated Statements and Other Financial Information

See Note 14c of our consolidated financial statements.

Legal Proceedings

In 2003, a third party sent us correspondence alleging that some of our products infringe upon patents held by such third party and offered to license these patents to us. Subsequent correspondence was exchanged during 2004, in which additional requests were made by the third party. As of December 31, 2010, we have recorded a provision of approximately $1.2 million, which we believe covers the probable loss from such allegations.

During April 2009, we received a letter from one of our resellers, in which the reseller raised certain claims that we caused it damages due to, among other things, our cessation of the development of one of our products. In March, 2010, the reseller filed a lawsuit against us in Germany and the court subsequently rendered a decision in our favor. The period for filing an appeal has passed and no appeal was filed and therefore, we have offset the provision that we recorded with respect to such allegations. We have since received a letter from Israeli counsel to the reseller in which certain allegations and threats of potential litigation in Israel were made against our company.

In September 2010, we received a letter from a shareholder, addressed to the Chairman of our Board of Directors, in which certain allegations were made with respect to certain actions and alleged inactions of ours, our directors and executive officers in connection with the self tender offer that we completed in September 2010. We have responded to the shareholder refuting all claims and denying any wrongdoings.

In December 2010, we received notice of a claim filed against Radvision Inc. by Nortel Networks Inc. and its affiliates and successors in the United States Bankruptcy Court for the district of Delaware. The plaintiffs are seeking the return of alleged preferential payments by the defendant and to disallow claims relating to amounts paid and claims available to the defendant pursuant to the bankruptcy proceedings to which the plaintiff was subject in the nominal amount of approximately US$137,000 for licensing fees during the second quarter of 2008. We are currently negotiating a potential settlement of this claim with the plaintiffs. We believe that this matter will not have a material adverse effect on our financial position.

We are periodically a party to routine litigation incidental to our business. We do not believe that we are a party to any pending legal proceeding that is likely to have a material adverse effect on our business, financial condition or results of operations.

Dividend Distributions Policy

We have never declared or paid any cash dividends to our shareholders. We currently intend to retain future earnings for use in our business and do not anticipate paying cash dividends on our ordinary shares in the foreseeable future. Any future dividend policy will be determined by our Board of Directors and will be based upon conditions then existing, including our results of operations, financial condition, current and anticipated cash needs, contractual restrictions and other conditions. In addition, our Articles of Association provide that the declaration of a dividend requires approval by an ordinary resolution of our shareholders, which may decrease but not increase the amount proposed by the Board of Directors.

According to the Israeli Companies Law, a company may distribute dividends out of its profits provided that there is no reasonable concern that such dividend distribution will prevent the company from paying all its current and foreseeable obligations, as they become due. Notwithstanding the foregoing, dividends may be paid with the approval of a court, provided that there is no reasonable concern that such dividend distribution will prevent the company from satisfying its current and foreseeable obligations, as they become due. Profits, for purposes of the Israeli Companies Law, means the greater of retained earnings or earnings accumulated during the preceding two years, after deducting previous distributions that were not deducted from the surpluses. In the event cash dividends are declared, such dividends will be paid in NIS.

Not applicable.

B. Memorandum and Articles of Association

Purposes and Objects of the Company

We are a public company registered under the Israel Companies Law as RADVISION Ltd., registration number 51-165181-2. Pursuant to our memorandum of association, we were formed for the purpose of developing, manufacturing and supplying products in the electronics field in general, and specifically, in the field of data communication.

The Powers of the Directors

Under the provisions of the Israel Companies Law and our Articles of Association, a director cannot participate in a meeting nor vote on a proposal, arrangement or contract in which he or she is materially interested. In addition, our directors cannot vote compensation to themselves or any members of their body without the approval of our Audit Committee and our shareholders at a general meeting. See “Item 6B. Directors, Senior Management and Employees – Compensation.”

Directors may not enter into borrowing arrangements on our behalf except in the manner approved by the Company. The Board of Directors has approved a resolution regarding signing authority to ensure the proper oversight and regulation of officers and directors acting on our behalf.

Rights Attached to Shares

Our authorized share capital consists of 45,000,000 ordinary shares of a nominal value of NIS 0.1 each. All outstanding ordinary shares are validly issued, fully paid and non-assessable.

The rights attached to the ordinary shares are as follows:

Dividend rights. Holders of our ordinary shares are entitled to the full amount of any cash or share dividend subsequently declared. The board of directors may declare interim dividends and propose the final dividend with respect to any fiscal year only out of the retained earnings, in accordance with the provisions of the Israeli Companies Law. Our Articles of Association provide that the declaration of a dividend requires approval by an ordinary resolution of the shareholders, which may decrease but not increase the amount proposed by the board of directors. See “Item 8A. Financial Information – Consolidated Statements and Other Financial Information – Dividend Distributions Policy.” If after one year a dividend has been declared and it is still unclaimed, the board of directors is entitled to invest or utilize the unclaimed amount of dividend in any manner to our benefit until it is claimed. We are not obligated to pay interest or linkage differentials on an unclaimed dividend. Also see “Item 10E. Additional Information – Taxation.”

Voting rights. Holders of ordinary shares have one vote for each ordinary share held on all matters submitted to a vote of shareholders. Such voting rights may be affected by the grant of any special voting rights to the holders of a class of shares with preferential rights that may be authorized in the future.

The quorum required for an ordinary meeting of shareholders consists of at least two shareholders present in person or by proxy who hold or represent, in the aggregate, at least one third of the voting rights of the issued share capital. A meeting adjourned for lack of a quorum generally is adjourned to the same day in the following week at the same time and place or any time and place as the directors designate in a notice to the shareholders. At the reconvened meeting, the required quorum consists of any two members present in person or by proxy.

An ordinary resolution, such as a resolution for the declaration of dividends, requires approval by the holders of a majority of the voting rights represented at the meeting, in person, by proxy or by written ballot and voting thereon. Under our Articles of Association, a special resolution, such as amending our memorandum of association or articles of association, approving any change in capitalization, winding-up, authorization of a class of shares with special rights, or other changes as specified in our articles of association, requires approval of a special majority, representing the holders of no less than 65% of the voting rights represented at the meeting in person, by proxy or by written ballot, and voting thereon.

Pursuant to our Articles of Association, our directors (except the outside directors) are elected at our annual general meeting of shareholders by a vote of the holders of a majority of the voting power represented and voting at such meeting and hold office until the next annual general meeting of shareholders and until their successors have been elected. All the members of our Board of Directors (except the outside directors) may be reelected upon completion of their term of office. For information regarding the election of outside directors, see “Item 6C. Directors, Senior Management and Employees – Directors and Senior Management - Board Practices - Election of Directors.”

Rights to share in our company’s profits. Our shareholders have the right to share in our profits distributed as a dividend and any other permitted distribution. See this Item 10B. “Additional Information – Memorandum and Articles of Association – Rights Attached to Shares – Dividend Rights.”

Rights in the event of liquidation. In the event of our liquidation, after satisfaction of liabilities to creditors, our assets will be distributed to the holders of ordinary shares in proportion to the nominal value of their holdings. This right may be affected by the grant of preferential dividend or distribution rights to the holders of a class of shares with preferential rights that may be authorized in the future.

Changing Rights Attached to Shares

According to our Articles of Association, in order to change the rights attached to any class of shares, unless otherwise provided by the terms of the class, such change must be adopted by a general meeting of the shareholders and by a separate general meeting of the holders of the affected class with a majority of 65% of the voting power participating in such meeting.

Annual and Extraordinary Meetings

Under the Israeli Companies Law, a company must convene an annual meeting of shareholders at least once every calendar year and within 15 months of the last annual meeting. Depending on the matter to be voted upon, notice of at least 21 days or 35 days prior to the date of the meeting is required. Our Board of Directors may, in its discretion, convene additional meetings as “special general meetings.” In addition, the board must convene a special general meeting upon the demand of two of the directors, 25% of the nominated directors, one or more shareholders having at least 5% of the outstanding share capital and at least 1% of the voting power in the company, or one or more shareholders having at least 5% of the voting power in the company. See this “Item 10B. Additional Information - Memorandum and Articles of Association- Rights Attached to Shares-Voting Rights.”

Limitations on the Rights to Own Securities in Our Company

Neither our Memorandum of Association nor our Articles of Association nor the laws of the State of Israel restrict in any way the ownership or voting of shares by non-residents, except with respect to subjects of countries which are in a state of war with Israel.

Changes in Our Capital

Changes in our capital are subject to the approval of the shareholders at a general meeting by a special majority of 65% of the votes of shareholders participating and voting in the general meeting.

Provisions Restricting Change in Control of Our Company

Tender Offer. A person wishing to acquire shares, or any class of shares, of a publicly traded Israeli company and who would as a result hold over 90% of the company’s issued and outstanding share capital, or a class of shares, is required by the Israeli Companies Law to make a tender offer to all of the company’s shareholders for the purchase of all of the remaining issued and outstanding shares of the company, or the class of shares, as the case may be. If the shareholders who do not respond to the offer hold less than 5% of the issued share capital of the company, or of the relevant class of shares, all of the shares that the acquirer offered to purchase will be transferred to the acquirer by operation of law. However, the shareholders may petition the court to determine that the consideration for the acquired shares is less than the shares’ fair value and that the acquiring party should pay the shares’ fair value. If the dissenting shareholders hold more than 5% of the issued and outstanding share capital of the company, or of the relevant class of shares, as the case may be, the acquirer may not acquire additional shares of the company from shareholders who accepted the tender offer if following such acquisition the acquirer would own over 90% of the company’s issued and outstanding share capital, or of the relevant class of shares.

The Israeli Companies Law provides that an acquisition of shares of a public company be made by means of a tender offer if as a result of the acquisition the purchaser would become the holder of a ‘‘control block.’’ Under the Israeli Companies Law, shares conferring 25% or more of the voting rights in the company constitute a ‘‘control block.’’ The requirement for a tender offer does not apply if there is already another holder of a control block. Similarly, the Israeli Companies Law provides that an acquisition of shares in a public company must be made by means of a tender offer if as a result of the acquisition the acquirer would hold more than 45% of the voting rights in the company, unless there is another person holding more than 45% of the voting rights in the company. These requirements do not apply if:

the acquisition was made in a private placement the object of which was to confer to the acquiring party a ‘‘control block’’ where there is no holder of a ‘‘control block,’’ or to confer to the acquiring party 45% of the voting rights in the company where there is no holder of 45% of the voting rights in the company, and the private placement received the general meeting’s approval;

the acquisition was from the holder of a ‘‘control block’’ and resulted in a person becoming the holder of a ‘‘control block;’’ or

the acquisition was from a shareholder holding more than 45% of the voting rights in the company and resulted in a person becoming a holder of more than 45% of the voting rights in the company.

Merger. The Israeli Companies Law permits merger transactions if approved by each party’s board of directors and, except under certain circumstances specified below, by the majority of each party’s shares voted on the proposed merger at a shareholders meeting convened upon prior notice of at least 35 days (which may be shortened to 14 days in certain circumstances). A merger is defined as the transfer of all assets and liabilities, including conditional, future, known and unknown debts of the target company to the surviving company, as a result of which the target company is liquidated, and stricken out of the Companies Register.

Under the Israeli Companies Law, if the approval of a general meeting of the shareholders is required, merger transactions may be approved by holders of a simple majority of the shares present and voting, in person or by proxy or by written ballot, at the general meeting convened to approve the transaction. If one of the merging companies, or a shareholder that holds 25% or more of the means of control of one of the merging companies, or a 25% shareholder, holds shares of the other merging company, then a dissenting vote of holders of the majority of the shares of the other merging company present and voting, excluding shares held by the merging company or a 25% shareholder thereof, or by anyone acting on behalf of either of them, their relatives and corporations controlled thereby, is sufficient to reject the merger transaction. Means of control are defined as any of the following: (i) the right to vote at a general meeting of a company; and (ii) the right to appoint a director of a company. If the transaction would have been approved but for the exclusion of the votes as previously indicated, a court may still approve the merger upon the request of holders of at least 25% of the voting rights of the company. The court will not approve a merger unless it is convinced that the merger is fair and reasonable, taking into account the values of the merging companies and the consideration offered to the shareholders. Upon the request of a creditor of either party to the proposed merger, the court may delay or prevent the merger if it concludes that there exists a reasonable concern that, as a result of the merger, the surviving company will be unable to satisfy the obligations of the merged company. In addition, a merger may not be completed unless at least 50 days have passed from the date that a proposal for approval of the merger was filed with the Israeli Registrar of Companies and 30 days from the date that shareholder approval of both merging companies was obtained.

Notwithstanding the foregoing, a merger is not subject to the approval of the shareholders of the target company if the target company is a wholly-owned subsidiary of the surviving company. A merger is not subject to the approval of the shareholders of the surviving company if:

the merger does not require the alteration of the memorandum or articles of association of the surviving company;

the acquiring company would not issue more than 20% of the voting rights thereof to the shareholders of the target company in the course of the merger and no person will become, as a result of the merger, a controlling shareholder of the surviving company, on a fully diluted basis;

neither the target company, nor any shareholder that holds 25% of the means of control of the target company is a shareholder of the surviving company; and

there is no person that holds 25% or more of the means of control in both companies.

Disclosure of Shareholders’ Ownership

The Israeli Securities Law, 5728-1968 and regulations promulgated thereunder contain various provisions regarding the ownership threshold above which shareholders must disclose their share ownership. However, these provisions do not apply to companies, such as ours, whose shares are publicly traded in Israel as well as outside of Israel. As a result of the listing of our ordinary shares on the Tel Aviv Stock Exchange, we are required pursuant to the Israeli Securities Law and the regulations promulgated thereunder to deliver to the Israeli Share Registrar, the Israeli Securities Exchange Commission and the Tel Aviv Stock Exchange, all reports, documents, forms and information received by us from our shareholders regarding their shareholdings, provided that such information was published or required to be published under applicable foreign law.

C. Material Contracts

While we have numerous contracts with customers, resellers and distributors we do not deem any such individual contract to be material.

D. Exchange Controls

The ownership or voting of our ordinary shares by non-residents of Israel, except with respect to citizens of countries which are in a state of war with Israel, is not restricted in any way by our Memorandum of Association or Articles of Association or by the laws of the State of Israel.

Israeli law and regulations do not impose any material foreign exchange restrictions on non-Israeli holders of our ordinary shares. In May 1998, a new “general permit” was issued under the Israeli Currency Control Law, 1978, which removed most of the restrictions that previously existed under such law, and enabled Israeli citizens to freely invest outside of Israel and freely convert Israeli currency into non-Israeli currencies. Also, there are currently no Israeli currency control restrictions on payments of dividends or other distributions with respect to our ordinary shares or the proceeds from the sale of the shares, except for the obligation of Israeli residents to file reports with the Bank of Israel regarding some transactions. However, legislation remains in effect under which currency controls can be imposed by administrative action at any time.

Non-residents of Israel, other than citizens of countries that are in a state of war with Israel, who purchase our ordinary shares will be able to convert dividends, if any, thereon, and any amounts payable upon our dissolution, liquidation or winding up, as well as the proceeds of any sale in Israel of our ordinary shares to an Israeli resident, into freely repatriable dollars, at the exchange rate prevailing at the time of conversion, provided that the Israeli income tax has been withheld (or paid) with respect to such amounts or an exemption has been obtained.

E. Taxation

The following is a discussion of Israeli and United States tax consequences material to our shareholders. To the extent that the discussion is based on new tax legislation which has not been subject to judicial or administrative interpretation, the views expressed in the discussion might not be accepted by the tax authorities in question. The discussion is not intended, and should not be construed, as legal or professional tax advice and does not exhaust all possible tax considerations.

You are urged to consult your own tax advisor as to the Israeli, United States and other tax consequences of the purchase, ownership and disposition of our ordinary shares, including, in particular, the effect of any non-Israeli, state or local taxes.

Israeli Tax Considerations

The following is a summary of the principal Israeli tax laws, applicable to us, of the Israeli Government programs from which we benefit and of Israeli foreign exchange regulations. This section also contains a discussion of material Israeli tax consequences to our shareholders who are not residents or citizens of Israel. This summary does not discuss all aspects of Israeli tax law that may be relevant to a particular investor in light of his or her personal investment circumstances, or to some types of investors subject to special treatment under Israeli law. Examples of investors subject to special treatment under Israeli law include residents of Israel, traders in securities, or persons who own, directly or indirectly, 10% or more of our outstanding voting capital, all of whom are subject to special tax regimes not covered in this discussion. Some parts of this discussion are based on new tax legislation that has not been subject to judicial or administrative interpretation. The discussion should not be construed as legal or professional tax advice and does not cover all possible tax consequences.

General Corporate Tax Structure

Israeli companies were generally subject to corporate tax at the rate of 25% in 2010. The corporate tax rate decreased to 24% for the 2011 tax year and will further decrease as follows: 23% for the 2012 tax year, 22% for the 2012 tax year, 21% for the 2014 tax year, 20% for the 2015 tax year and 18% for the 2016 tax year and thereafter. Israeli companies are generally subject to capital gains tax at a rate of 25% for capital gains (other than gains deriving from the sale of listed securities) derived after January 1, 2003, and such tax rate is scheduled to be the corporate tax rate for future tax years. However, the corporate tax rate is effectively reduced for income derived from an approved enterprise and beneficiary enterprise, as discussed below.

Tax Benefits under the Law for the Encouragement of Capital Investments, 1959

We have two capital investment programs that have been granted “approved enterprise” status under the Law for the Encouragement of Capital Investments, 1959, commonly referred to as the Investment Law, and two programs that qualify as “beneficiary enterprises” pursuant to an amendment to the Investment Law that came into effect on April 1, 2005. One of the beneficiary enterprise programs was converted from a previously approved enterprise program pursuant to the approval of the Israel Tax Authority that we received in October 2007.

Prior to an April 2005 amendment to the Investment Law, the Investment Law provided that capital investments in a production facility (or other eligible assets) may be designated as an approved enterprise upon prior approval from the Investment Center of the Israel Ministry of Industry, Trade and Labor, or the Investment Center. Each certificate of approval for an approved enterprise relates to a specific investment program, delineated both by the financial scope of the investment and by the physical characteristics of the facility or the asset. If a company has more than one approval or only a portion of its capital investment is approved, its effective tax rate is the result of a weighted combination of the applicable rates.

The April 2005 amendment to the Investment Law revised the criteria for investment programs qualified to receive tax benefits, which, if qualified, are referred to as a “beneficiary enterprise” (rather than the previous terminology of “approved enterprise”). Companies that meet the specified criteria will receive the tax benefits without need for prior approval and instead, a company may claim the tax benefits offered by the Investment Law directly in its tax returns. Among other things, the April 2005 amendment provides tax benefits to both local and foreign investors. The period of tax benefits for a new beneficiary enterprise commences in the year that is the later of: (i) the year in which taxable income is first generated by a company, or (ii) a year selected by the company for commencement, on the condition that the company meets certain provisions provided by the Investment Law. The amendment does not apply to investment programs approved prior to April 1, 2005 and applies only to new investment programs. We began to generate income under the provision of the amendment as of the beginning of 2006.

Tax benefits are available under the April 2005 amendment to production facilities (or other eligible facilities), which are generally required to derive more than 25% of their business income from export. In order to receive the tax benefits, the April 2005 amendment states that the company must make an investment in the beneficiary enterprise exceeding a certain percentage or a minimum amount specified in the Investment Law. Such investment may be made over a period of no more than three years ending at the end of the year in which the company requested to have the tax benefits apply to the beneficiary enterprise, referred to as the "Year of Election." Where the company requests to have the tax benefits apply to an expansion of existing facilities, then only the expansion will be considered a beneficiary enterprise and the company’s effective tax rate will be the result of a weighted average of the applicable rates. In such case, the minimum investment required in order to qualify as a beneficiary enterprise is required to exceed a certain percentage or a minimum amount of the company’s production assets at the end of the year before the expansion.

The amended Investment Law specifies certain conditions that a beneficiary enterprise has to comply with in order to be entitled to benefits. These conditions include among others:

that the beneficiary enterprise’s revenues during the applicable tax year from any single market (i.e. country or a separate customs territory) do not exceed 75% of the beneficiary enterprise’s aggregate revenues during such year; or

that 25% or more of the beneficiary enterprise’s revenues during the applicable tax year are generated from sales into a single market (i.e. country or a separate customs territory) with a population of at least 12 million residents.

A company that owns an approved enterprise is eligible for governmental grants, but may elect to receive an alternative package comprised of tax benefits, referred to as the “alternative track.” Under the alternative track, a company’s undistributed income derived from an approved enterprise is exempt from corporate tax for an initial period (two to ten years, depending on the geographic location of the approved enterprise and beneficiary enterprise within Israel). The exemption begins in the first year that the company realizes taxable income from the approved enterprise. The benefits for a benefited enterprise are similar to the "alternative track" of an approved enterprise.

After expiration of the initial tax exemption period, the company is eligible for a reduced corporate tax rate of 10% to 25% for the following five to eight years, depending on the extent of foreign investment in the company (as shown in the table below). The benefits period is limited to 12 years from completion of the investment under the approved plan or 14 years from the start of the tax year in which the approval was granted, whichever is earlier. A company in which more than 25% of the shareholders are non-residents of Israel, defined under the Investment Law as a Foreign Investors Company, may be eligible for benefits for an extended period of up to ten years.

The tax benefits under the Investment Law relate only to taxable income attributable to the specific approved enterprise and/or beneficiary enterprise. To the extent we have more than one approved enterprise and/or beneficiary enterprise or only a portion of our capital investments are derived from approved or beneficiary enterprises, our effective tax rate will be the result of a weighted combination of the applicable rates.

Percent of Foreign Ownership	Rate of Reduced Tax	Reduced Tax Period	Tax Exemption Period
0-25%	25%	5 years	2 years
25-49%	25%	8 years	2 years
49-74%	20%	8 years	2 years
74-90%	15%	8 years	2 years
90-100%	10%	8 years	2 years

If a company distributes dividends or completes a liquidation from tax-exempt approved enterprise and/or beneficiary enterprise income, the company will be taxed on the otherwise exempt income at the same reduced corporate tax rate that applies to it after the initial exemption period. Distribution of dividends or completion of a liquidation derived from approved enterprise and beneficiary enterprise income that was taxed at reduced rates, but not tax exempt, does not result in additional tax consequences to the company. Shareholders who receive dividends derived from approved enterprise and beneficiary enterprise income are generally taxed at a rate of 15%, which is withheld and paid by the company paying the dividend, if the dividend is distributed during the benefits period or within the following 12 years (but the 12-year limitation does not apply to a Foreign Investors Company).

The benefits available to an approved enterprise program and a beneficiary enterprise program are dependent upon the fulfillment of conditions stipulated in the Investment Law and related regulations (which include making specified investments in property and equipment, and financing a percentage of these investments with share capital) and, for an approved enterprise, the conditions contained in the certificate of approval from the Investment Center, and for our beneficiary enterprises, the conditions contained in a pre-ruling that we received from the Israeli Tax Authority in October 2007. If we do not fulfill these conditions, in whole or in part, the benefits can be cancelled and we may be required to refund the amount of the benefits, linked to the Israeli consumer price index plus interest. We believe that our approved enterprise and beneficiary enterprise programs currently operate in compliance with all applicable conditions and criteria, but we cannot assure you that they will continue to do so.

We have derived, and expect to continue to derive, a substantial portion of our operating income from our approved enterprise and beneficiary enterprise facilities. We are therefore eligible for a tax exemption from income for two years, which is allocated to each of the programs on undistributed approved enterprise and beneficiary enterprise income, and an additional subsequent period of reduced corporate tax rates ranging between 10% and 25%, depending on the level of foreign ownership of our shares. The tax benefits attributable to our current approved enterprises and beneficiary enterprises are scheduled to expire in phases between 2009 and 2017. We intend to reinvest the entire amount of our tax-exempt income and not to distribute such income as a dividend.

In December 2010, the Israeli Parliament passed the Law for Economic Policy for 2011 and 2012 (Amended Legislation), 2011, which prescribes, among other things, amendments to the Investment Law, effective as of January 1, 2011. According to the amendment, the benefit tracks under the Investment Law were modified and a uniform tax rate will apply to all of the income of an approved or beneficiary enterprise. Companies may elect to irrevocably implement the amendment (while waiving benefits provided under the Investment Law as currently in effect) and subsequently would be subject to the amended tax rates that are: 2011 and 2012 - 15%, 2013 and 2014 - 12.5% and in 2015 and thereafter - 12%. We are examining the possible effect of the amendment on the financial statements, if at all, and at this time have not yet decided whether to apply the amendment Tax Benefits and Grants for Research and Development

Israeli tax law permits, under specific conditions, a tax deduction in the year incurred for expenditures, including capital expenditures, relating to scientific research and development projects, if the expenditures are approved by the relevant Israeli government ministry, determined by the field of research, and the research and development is for the promotion of the company and is carried out by or on behalf of the company seeking such deduction. Expenditures not so approved are deductible over a three-year period. However, expenditures from proceeds made available to us through government grants are not deductible according to Israeli law.

Tax Benefits Under the Law for the Encouragement of Industry (Taxes), 1969

According to the Law for the Encouragement of Industry (Taxes), 1969, or the Industry Encouragement Law, an Industrial Company is a company resident in Israel, at least 90% of the income of which, in a given tax year, determined in Israeli currency (exclusive of income from some government loans, capital gains, interest and dividends), is derived from an industrial enterprise owned by it. An “industrial enterprise” is defined as an enterprise whose major activity in a given tax year is industrial production activity.

Under the Industry Encouragement Law, Industrial Companies are entitled to the following preferred corporate tax benefits:

amortization of purchases of acquired technology and patents over an eight-year period for tax purposes;

amortization of specified expenses incurred in connection with a public issuance of securities over a three-year period for tax purposes;

right to elect, under specified conditions, to file a consolidated tax return with additional related Israeli Industrial Companies; and

accelerated depreciation rates on equipment and buildings.

Eligibility for benefits under the Industry Encouragement Law is not subject to receipt of prior approval from any governmental authority. Under the Industry Encouragement Law, an "Industrial Company" is defined as a company resident in Israel, at least 90% of the income of which (exclusive of income from capital gains, direct real estate tax, interest and dividend) in any tax year, is derived from an "Industrial Company" owned by it. An "Industrial Company" is defined as an enterprise whose primary activity in a given tax year is industrial production activity. We cannot assure you that we will continue to qualify as an Industrial Company or that the benefits described above will be available to us in the future.

Taxation of Dividends Paid on our Ordinary Shares

Taxation of Israeli Shareholders

Israeli resident individuals are generally subject to Israeli income tax on the receipt of dividends paid on our ordinary shares, other than bonus shares (share dividends) or stock dividends, at the rate of 20%, or 25% for a shareholder that is considered a significant shareholder (within the meaning of the Israeli Income Tax Ordinance, which is a shareholder that holds directly or indirectly, including with others, at least 10% of any means of control in the company ) at any time during the 12-month period preceding such distribution. Dividends paid on our ordinary shares to Israeli companies are exempt from such tax, except for dividends distributed from income derived outside of Israel, which are subject to the 25% tax rate.

Dividends paid from income derived from any of our approved enterprises or beneficiary enterprises are subject to tax, which is withheld at the source, at the rate of 15%, although we cannot assure you that we will designate the profits that are being distributed in a way that will reduce shareholders’ tax liability to this tax rate.

Taxation of Non-Israeli Shareholders

Non-residents of Israeli are generally subject to Israeli income tax on the receipt of dividends paid on our ordinary shares, at the rates applicable to Israeli residents, which tax will be withheld at source, unless a different rate is provided in a treaty between Israel and the shareholder’s country of residence.

Under the U.S.-Israel Treaty, the maximum Israeli withholding tax on dividends paid by us is 25%. Dividends of an Israeli company distributed from income of an approved enterprise or beneficiary enterprise are subject to a 15% withholding tax under Israeli law. The U.S.-Israel Tax Treaty further provides for a 12.5% Israeli dividend withholding tax on dividends paid by an Israeli company to a U.S. corporation owning at least 10% or more of such Israeli company’s issued voting power for, in general, the part of the tax year which precedes the date of payment of the dividend and the entire preceding tax year, provided such U.S. corporation meets certain limitations concerning the amount of its dividend and interest income. The lower 12.5% rate applies only to dividends from income not derived from an approved enterprise or beneficiary enterprise in the applicable period and does not apply if the company has more than 25% of its gross income derived from certain types of passive income. Residents of the United States generally will have withholding tax in Israel deducted at source. They may be entitled to a credit or deduction for U.S. federal income tax purposes in the amount of the taxes withheld, subject to detailed rules contained in U.S. tax legislation.

Capital gains taxes on sales of our ordinary shares

Israeli law generally imposes a capital gains tax on the sale of any capital assets by residents of Israel, as defined for Israeli tax purposes, and on the sale of assets located in Israel, including shares in Israeli companies, by both residents and non-residents of Israel, if those assets are either (i) located in Israel;(ii) are shares or right to shares in an Israeli resident corporation ;(iii) represent, directly or indirectly , rights to assets located in Israel unless a specific exemption is available or unless a tax treaty between Israel and the shareholder’s country of residence provides otherwise. The Israeli Tax Ordinance distinguishes between real gain and inflationary surplus. The inflationary surplus is a portion of the total capital gain, which is equivalent to the increase of the relevant asset’s purchase price, which is attributable to the increase in the Israeli consumer price index, or a foreign currency exchange rate, between the date of purchase and the date of sale. The real gain is the excess of the total capital gain over the inflationary surplus.

Taxation of Israeli Residents

The tax rate generally applicable to the capital gains derived from the sale of shares, whether listed on a stock market or not, is 20% for Israeli individuals, unless such shareholder claims a deduction for financing expenses in connection with such shares, in which case the gain will generally be taxed at a rate of 25%. Additionally, if such shareholder is considered a “significant shareholder” at any time during the 12-month period preceding such sale (i.e., such shareholder holds directly or indirectly, including jointly with others, at least 10% of any means of control in the company) the tax rate will be 25%. Israeli companies are subject to the corporate tax rate on capital gains derived from the sale of listed shares. However, different tax rates may apply to dealers in securities and shareholders who acquired their shares prior to an initial public offering.

The tax basis of our shares acquired prior to January 1, 2003 will generally be determined in accordance with the average closing share price in the three trading days preceding January 1, 2003. However, a request may be made to the tax authorities to consider the actual adjusted cost of the shares as the tax basis if it is higher than such average price.

Taxation of Non-Israeli Residents. Capital gains from the sale of our ordinary shares by non-Israeli shareholders are exempt from Israeli taxation, provided that the capital gain is not derived from a permanent establishment in Israel and provided such shareholders did not acquire their shares prior to our initial public offering (in which case a partial exemption may be available). However, non-Israeli corporations will not be entitled to such exemption if Israeli residents (i) have a controlling interest of 25% or more in such non-Israeli corporation, or (ii) are the beneficiaries of or are entitled to 25% or more of the revenues or profits of such non-Israeli corporation, whether directly or indirectly.

In addition, the sale, exchange or disposition of our ordinary shares by a shareholder who is a U.S. resident (for purposes of the U.S.-Israel Tax Treaty) and who holds ordinary shares as a capital asset is also exempt from Israeli capital gains tax under the U.S.-Israel Tax Treaty unless either (i) the shareholder holds, directly or indirectly, shares representing 10% or more of our voting power during any part of the 12-month period preceding such sale or (ii) the capital gains arising from such sale are attributable to a permanent establishment of the shareholder located in Israel. If the above conditions are not met, the U.S. resident would be subject to Israeli tax, to the extent applicable.

United States Federal Income Tax Consequences

The following discussion summarizes the material U.S. federal income tax considerations applicable to the purchase, ownership and disposition of our ordinary shares. Unless otherwise stated, this summary deals only with shareholders that are U.S. Holders (as defined below) who hold their ordinary shares as capital assets.

As used in this section, the term “U.S. Holder” means a beneficial owner of an ordinary share who is:

an individual citizen or resident of the United States or an individual treated as a U.S. citizen or resident for U.S. federal income tax purposes;

a corporation or other entity taxable as a corporation for U.S. federal income tax purposes created or organized in or under the laws of the United States, any State or the District of Columbia;

an estate, the income of which is subject to U.S. federal income taxation regardless of its source; or

any trust if (A)(i) a court within the United States is able to exercise primary supervision over the administration of the trust and (ii) one or more United States persons have the authority to control all substantial decisions of the trust, or (B) such trust validly elects to be treated as a United States person.

The term “Non-U.S. Holder” means a beneficial owner of an ordinary share that is an individual, corporation, estate or trust and is not a U.S. Holder. The tax consequences to a Non-U.S. Holder may differ substantially from the tax consequences to a U.S. Holder. Certain aspects of U.S. federal income tax relevant to a Non-U.S. Holder are discussed below.

This description is based on provisions of the U.S. Internal Revenue Code of 1986, as amended (the “Code”), existing and proposed U.S. Treasury regulations promulgated thereunder, administrative and judicial interpretations thereof, and the US-Israel Tax Treaty, each as in effect as of the date of this prospectus. These sources may change, possibly with retroactive effect, and are open to differing interpretations. This description does not discuss all aspects of U.S. federal income taxation that may be applicable to investors in light of their particular circumstances or to investors who are subject to special treatment under U.S. federal income tax law, including:

insurance companies;

dealers in stocks, securities or currencies;

financial institutions and financial services entities;

real estate investment trusts;

regulated investment companies;

persons that receive ordinary shares in connection with the performance of services;

tax-exempt organizations;

persons that hold ordinary shares as part of a straddle or appreciated financial position or as part of a hedging, conversion or other integrated instrument;

persons who acquire their ordinary shares through the exercise or cancellation of employee stock options or otherwise as consideration for their services;

individual retirement and other tax-deferred accounts;

expatriates of the United States and certain former long-term residents of the United States;

persons liable for the alternative minimum tax;

persons having a “functional currency” other than the U.S. dollar; and

direct, indirect or constructive owners of 10% or more, by voting power or value, of our company.

If a partnership or an entity treated as a partnership for U.S. federal income tax purposes owns ordinary shares, the U.S. federal income tax treatment of a partner in such a partnership will generally depend upon the status of the partner and the activities of the partnership. A partnership that owns ordinary shares and the partners in such partnership should consult their tax own advisors about the U.S. federal income tax consequences of holding and disposing of ordinary shares.

This discussion does not consider the possible application of U.S. federal gift or estate tax or alternative minimum tax.

All investors are urged to consult their own tax advisors as to the particular tax consequences to them of an investment in our ordinary shares, including the effect and applicability of United States federal, state, local and foreign income and other tax laws (including estate and gift tax laws) and tax treaties.

Distributions Paid on the Ordinary Shares

Subject to the discussion below under “Passive Foreign Investment Company Considerations,” a U.S. Holder generally will be required to include in his or her gross income as ordinary dividend income the amount of any distributions paid on the ordinary shares, including the amount of any Israeli taxes withheld, to the extent that those distributions are paid out of our current or accumulated earnings and profits, as determined for U.S. federal income tax purposes. Subject to the discussion below under “Passive Foreign Investment Company Considerations,” distributions in excess of our earnings and profits will be applied against and will reduce the U.S. Holder’s tax basis in its ordinary shares and, to the extent they exceed that tax basis, will be treated as gain from a sale or exchange of those ordinary shares. Our dividends will not qualify for the dividends-received deduction applicable in some cases to U.S. corporations.

Dividends that we pay in NIS, including the amount of any Israeli taxes withheld therefrom, will be included in your income in a U.S. dollar amount calculated by reference to the exchange rate in effect on the day such dividends are received, regardless of whether the payment is in fact converted into U.S. dollars. A U.S. Holder who receives payment in NIS and converts NIS into U.S. dollars at an exchange rate other than the rate in effect on such day will have a foreign currency exchange gain or loss that would be treated as ordinary income or loss. U.S. Holders should consult their own tax advisors concerning the U.S. tax consequences of acquiring, holding and disposing of NIS.

Subject to certain limitations, “qualified dividend income” received by a noncorporate U.S. Holder in tax years beginning on or before December 31, 2012 will be subject to tax at a reduced maximum tax rate of 15%. Distributions taxable as dividends paid on the ordinary shares should qualify for the 15% rate provided that we are not a passive foreign investment company (see disclosure below) for U.S. tax purposes and that either: (i) we are entitled to benefits under the income tax treaty between the United States and Israel (the “U.S.-Israel Tax Treaty”) or (ii) the ordinary shares are readily tradable on an established securities market in the United States and certain other requirements are met. We believe that we are entitled to benefits under the U.S.-Israel Tax Treaty and that the ordinary shares currently will be readily tradable on an established securities market in the United States. However, no assurance can be given that the ordinary shares will remain readily tradable. The rate reduction does not apply unless certain holding period requirements are satisfied. With respect to the ordinary shares, the U.S. Holder must have held such shares for at least 61 days during the 121-day period beginning 60 days before the ex-dividend date. The rate reduction also does not apply to dividends received from passive foreign investment companies, see discussion below, or in respect of certain hedged positions or in certain other situations. The legislation enacting the reduced tax rate contains special rules for computing the foreign tax credit limitation of a taxpayer who receives dividends subject to the reduced tax rate. U.S. Holders of ordinary shares should consult their own tax advisors regarding the effect of these rules in their particular circumstances.

Subject to the discussion below under “Information Reporting and Back-up Withholding,” a Non-U.S. Holder generally will not be subject to U.S. federal income or withholding tax on dividends received on ordinary shares unless that income is effectively connected with the conduct by that Non-U.S. Holder of a trade or business in the United States, in which case a corporate Non-U.S. Holder may also be subject to the U.S. branch profits tax.

Foreign Tax Credit

Any dividend income resulting from distributions we pay to a U.S. Holder with respect to the ordinary shares generally will be treated as foreign source income for U.S. foreign tax credit limitation purposes. Subject to certain conditions and limitations, Israeli tax withheld on dividends may be deducted from taxable income or credited against a U.S. Holder’s U.S. federal income tax liability. The limitation on foreign taxes eligible for credit is calculated separately with respect to specific classes of income. For this purpose, any dividend that we distribute generally will constitute “passive category income,” or, in the case of certain U.S. Holders, “general category income.” The rules relating to the determination of foreign source income and the foreign tax credit are complex, and the availability of a foreign tax credit depends on numerous factors. Each investor who is a U.S. Holder should consult with its own tax advisor to determine whether its income with respect to the ordinary shares would be foreign source income and whether and to what extent that investor would be entitled to a foreign tax credit.

Disposition of Ordinary Shares

Upon the sale or other disposition of ordinary shares, subject to the discussion below under “Passive Foreign Investment Company Considerations,” a U.S. Holder generally will recognize capital gain or loss equal to the difference between the amount realized on the disposition and the holder’s adjusted tax basis in the ordinary shares. U.S. Holders should consult their own advisors with respect to the tax consequences of the receipt of a currency other than U.S. dollars upon such sale or other disposition.

Gain or loss upon the disposition of the ordinary shares will be treated as long-term if, at the time of the sale or disposition, the ordinary shares were held for more than one year. The deductibility of capital losses by a U.S. Holder is subject to limitations. In general, any gain or loss recognized by a U.S. Holder on the sale or other disposition of ordinary shares will be U.S. source income or loss for U.S. foreign tax credit purposes. U.S. Holders should consult their own tax advisors concerning the source of income for U.S. foreign tax credit purposes and the effect of the U.S.-Israel Tax Treaty on the source of income.

that gain is effectively connected with the conduct by the Non-U.S. Holder of a trade or business in the United States, and, if a tax treaty applies, is attributable to a permanent establishment or fixed base of the Non-U.S. Holder in the United States; or

in the case of any gain realized by an individual Non-U.S. Holder, that holder is present in the United States for 183 days or more in the taxable year of the sale or exchange, and other conditions are met.

Passive Foreign Investment Company Considerations

There is a substantial risk that we were a passive foreign investment company, or PFIC, for U.S. federal income tax purposes for the 2010 tax year. Special U.S. federal income tax rules apply to U.S. Holders owning shares of a PFIC.

For U.S. federal income tax purposes, a non-U.S. corporation will be considered a PFIC for any taxable year in which, after applying certain look-through rules, 75% or more of its gross income consists of specified types of passive income, or 50% or more of the average value of its assets consists of assets that produce, or are held for the production of, passive income. For this purpose, passive income includes generally dividends, interest, royalties, rents, annuities and the excess of gains over losses from the disposition of assets which produce passive income. As a result of our substantial cash position, we believe that there is a substantial risk that we qualified as a PFIC, for U.S. federal income tax purposes, during the taxable year ended December 31, 2010, under a literal application of the asset test described above, which looks solely to the market value. We believe that there is a substantial risk that we will also qualify as a PFIC during the taxable year ending December 31, 2011.

If we were classified as a PFIC, a U.S. Holder could be subject to increased tax liability upon the sale or other disposition of ordinary shares or upon the receipt of amounts treated as “excess distributions.” Under these rules, the excess distribution and any gain would be allocated ratably over the U.S. Holder’s holding period for the ordinary shares, and the amount allocated to the current taxable year and any taxable year prior to the first taxable year in which we were a PFIC would be taxed as ordinary income. The amount allocated to each of the other taxable years would be subject to tax at the highest marginal tax rate in effect for the applicable class of taxpayer for that year, and an interest charge for the deemed deferral benefit would be imposed on the resulting tax allocated to such other taxable years. The tax liability with respect to the amount allocated to years prior to the year of the disposition, or “excess distribution,” cannot be offset by any net operating losses. In addition, holders of stock in a PFIC may not receive a “step-up” in basis on shares acquired from a decedent. If we are a PFIC in any year, a U.S. Holder would be required to file an annual return on IRS Form 8621 regarding distributions received with respect to ordinary shares and any gain realized on the disposition of ordinary shares.

The PFIC tax consequences described above will not apply to a U.S. Holder if the U.S. Holder makes an election to treat us as a qualified electing fund, or QEF. If a U.S. Holder makes a timely QEF election, the U.S. Holder would be required to include in income for each taxable year its pro rata share of our ordinary earnings as ordinary income and its pro rata share of our net capital gain as long-term capital gain, whether or not such amounts are actually distributed to the U.S. Holder. However, a U.S. Holder would not be eligible to make a QEF election unless we comply with certain applicable information reporting requirements.

As an alternative to making a QEF election, a U.S. Holder of PFIC stock which is publicly traded may in certain circumstances avoid certain of the tax consequences generally applicable to holders of a PFIC by electing to mark the stock to market annually and recognizing as ordinary income or loss each year an amount equal to the difference as of the close of the taxable year between the fair market value of the PFIC stock and the U.S. Holder’s adjusted tax basis in the PFIC stock. Losses would be allowed only to the extent of net mark-to-market gain previously included by the U.S. Holder under the election for prior taxable years. Income recognized and deductions allowed under the mark-to-market provisions, as well as any gain or loss on the disposition of ordinary shares with respect to which the mark to market election is made, is generally treated as ordinary income or loss (except that loss is treated as capital loss to the extent the loss exceeds the net mark-to-market gains, if any, that a U.S. Holder included in its income with respect to such ordinary shares in prior years). However, gain or loss from the disposition of ordinary shares (as to which a “mark-to-market” election was made) in a year in which we are no longer a PFIC, will be capital gain or loss. The mark-to-market election is available for so long as our ordinary shares constitute “marketable stock,” which includes stock of a PFIC that is “regularly traded” on a “qualified exchange or other market.” Generally, a “qualified exchange or other market” includes a national securities exchange that is registered with the Securities and Exchange Commission or the national market system established pursuant to Section 11A of the Securities Exchange Act of 1934. A class of stock that is traded on one or more qualified exchanges or other markets is “regularly traded” on an exchange or market for any calendar year during which that class of stock is traded, other than in de minimis quantities, on at least 15 days during each calendar quarter. We believe that The NASDAQ Global Select Market will constitute a qualified exchange or other market for this purpose. However, we can not be certain that our ordinary shares will continue to trade on The NASDAQ Global Select Market or that the ordinary shares will be regularly traded for this purpose.

The rules applicable to owning shares of a PFIC are complex, and each holder who is a U.S. Holder should consult with its own tax advisor regarding the consequences of investing in a PFIC.

Information Reporting and Backup Withholding

Payments in respect of ordinary shares may be subject to information reporting to the U.S. Internal Revenue Service and to U.S. backup withholding tax at a rate equal to the fourth lowest income tax rate applicable to individuals (which, under current law, is 28%). Backup withholding will not apply, however, if you (i) are a corporation or come within certain exempt categories, and demonstrate the fact when so required, or (ii) furnish a correct taxpayer identification number and make any other required certification. U.S. Holders who are required to establish their exempt status generally must provide such certification on IRS Form W-9.

Backup withholding is not an additional tax. Amounts withheld under the backup withholding rules may be credited against a U.S. Holder’s U.S. tax liability, and a U.S. Holder may obtain a refund of any excess amounts withheld under the backup withholding rules by filing the appropriate claim for refund with the IRS.

Any U.S. holder who holds 10% or more in vote or value of our ordinary shares may be subject to certain additional United States information reporting requirements.

U.S. Gift and Estate Tax

An individual U.S. Holder of ordinary shares will generally be subject to U.S. gift and estate taxes with respect to ordinary shares in the same manner and to the same extent as with respect to other types of personal property.

H. Documents on Display

We are subject to certain of the reporting requirements of the Securities and Exchange Act of 1934, as amended, or the Exchange Act, as applicable to “foreign private issuers” as defined in Rule 3b-4 under the Exchange Act. As a foreign private issuer, we are exempt from certain provisions of the Exchange Act. Accordingly, our proxy solicitations are not subject to the disclosure and procedural requirements of Regulation 14A under the Exchange Act, and transactions in our equity securities by our officers and directors are exempt from reporting and the “short-swing” profit recovery provisions contained in Section 16 of the Exchange Act. In addition, we are not required under the Exchange Act to file periodic reports and financial statements as frequently or as promptly as U.S. companies whose securities are registered under the Exchange Act. However, we file with the Securities and Exchange Commission an annual report on Form 20-F containing financial statements audited by an independent accounting firm. We also submit to the Securities and Exchange Commission reports on Form 6-K containing (among other things) press releases and unaudited financial information. We post our annual report on Form 20-F and quarterly unaudited financial statements filed on Form 6-K on our website (www.radvision.com) promptly following the filing of such reports with the Securities and Exchange Commission. The information on our website is not incorporated by reference into this annual report.

This annual report and the exhibits thereto and any other document we file pursuant to the Exchange Act may be inspected without charge and copied at prescribed rates at the Securities and Exchange Commission public reference room at 100 F Street, N.E., Room 1580, Washington, D.C. 20549. You may obtain information on the operation of the Securities and Exchange Commission’s public reference room in Washington, D.C. by calling the Securities and Exchange Commission at 1-800-SEC-0330.

ITEM 11. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISKS

We are exposed to a variety of risks, including changes in interest rates and foreign currency fluctuations.

We are exposed to market risks arising primarily from weak economic conditions in the markets in which we sell our products and from changes in exchange rates or interest rates.

The securities in our portfolio are rated at the least as BBB. Securities representing about 19% of our marketable securities portfolio are rated as AAA.

Interest Rate Risk

As of December 31, 2010, we had cash and cash equivalents, short -term deposits and short and long-term marketable securities of $116.4 million. We invest our cash surplus in time deposits, cash deposits, U.S. federal agency securities and corporate bonds with an average credit rating of AA. These investments are not purchased for trading or other speculative purposes.

The performance of the capital markets affects the value of funds held by us in marketable securities. These assets are subject to market fluctuations and yield uncertain returns, which may fall below our projected return rates. Although we believe that we generally adhere to conservative investment guidelines, the 2008 and 2009 financial crisis resulted in immaterial impairments of the carrying value of certain of our investment assets. We expect that market conditions will continue to fluctuate and that the fair value of our investments may be impacted accordingly. Uncertain economic conditions may lead to additional impairments. Realized or unrealized losses in our investments or in our other financial assets may adversely affect our financial condition.

One of our primary market risk exposures is to changes in interest rates as a result of our investment in marketable securities. Our marketable securities portfolio includes states and political subdivisions debt instruments, corporate debt instruments and auction rate securities. A decline in market interest rates could have an adverse effect on our investment income. In a declining interest rate environment, borrowers may seek to refinance their borrowings at lower rates and, accordingly, prepay or redeem securities we hold more quickly than we initially expected. This action may cause us to reinvest the redeemed proceeds in lower yielding investments. An increase in market interest rates could also have an adverse effect on the value of our investment portfolio, for example, by decreasing the fair value of the fixed income securities that comprise a substantial majority of our investment portfolio.

Foreign Currency Exchange Risk

We develop products in Israel and sell them in the Americas, the Asia-Pacific region and in the Europe, Middle East and Africa region. As a result our financial results could be affected by factors such as changes in foreign currency exchange rates or weak economic conditions in foreign markets.

Since most of our sales are quoted in dollars, and a portion of our expenses are incurred in NIS and Euro, our results may be adversely affected by the appreciation of the NIS and Euro against the U.S. dollar or by a change in the rate of inflation in Israel or if such change in the rate of inflation is not offset, or is offset on a lagging basis, by a corresponding depreciation of the NIS and Euro against the U.S. dollar and other foreign currencies. In 2008, 2009 and 2010, the NIS appreciated by approximately 1.1%, 0.7% and 6.0%, respectively, against the U.S. dollar. In 2008, 2009 and 2010, the annual inflation rate in Israel was approximately 3.8%, 3.9% and 2.7%, respectively.

Use of Proceeds

We sold 4,370,000 of our ordinary shares in our initial public offering on March 14, 2000. The aggregate offering price of the shares sold was $87.4 million. The total expenses of the offering were approximately $8,950,000. None of such expenses were paid directly or indirectly to directors, officers, persons owning 10% or more of any class of equity securities of our company or to our affiliates. The net public offering proceeds to us, after deducting the total expenses were approximately $78,500,000. Such proceeds have been invested in liquid investments and short-term bank deposits and have been used for working capital purposes. As of December 31, 2010, we had $65.5 million in cash, cash equivalents and short-term bank deposits.

ITEM 15. CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in its Exchange Act reports is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms, and that such information is accumulated and communicated to our chief executive officer and chief financial officer to allow timely decisions regarding required disclosure. Our management, including our chief executive officer and chief financial officer, conducted an evaluation of our disclosure controls and procedures, as defined under Exchange Act Rule 13a-15(e), as of the end of the period covered by this Annual Report on Form 20-F. Based upon that evaluation, our chief executive officer and chief financial officer have concluded that, as of such date, our disclosure controls and procedures were effective.

Management's Annual Report on Internal Control over Financial Reporting

Our management, including our chief executive officer and chief financial officer, is responsible for establishing and maintaining adequate internal control over financial reporting, as defined under Exchange Act Rules 13a-15(f) and 15d-15(f). Our internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the United States. Internal control over financial reporting includes those policies and procedures that: (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets, (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that our receipts and expenditures are being made only in accordance with appropriate authorizations; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of our assets that could have a material effect on the financial statements.

Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2010. In conducting its assessment of internal control over financial reporting, management based its evaluation on the framework in “Internal Control – Integrated Framework” issued by the Committee of Sponsoring Organizations, or the COSO, of the Treadway Commission. Based on that assessment, our management has concluded that our internal control over financial reporting was effective as of December 31, 2010.

The effectiveness of our internal control over financial reporting as of December 31, 2010 has been audited by Kost Forer Gabbay & Kasierer, a member of Ernst & Young Global, an independent registered public accounting firm that audited and reported on our consolidated financial statements for the year ended December 31, 2010. The attestation report of our independent registered public accounting firm is set forth on page F-3 of our audited consolidated financial statements set forth in Item 18 “Financial Statements,” and is incorporated herein by reference.

Changes in Internal Control over Financial Reporting

There was no change in our internal controls over financial reporting that occurred during the period covered by this annual report that has materially affected, or is reasonably likely to materially affect, our internal controls over financial reporting.

Pre-Approval Policies and Procedures

Our Audit Committee has adopted policies and procedures for the pre-approval of audit and non-audit services rendered by our independent registered public accountants, Kost Forer Gabbay & Kasierer, a member of Ernst & Young Global. The policy generally pre-approves certain specific services in the categories of audit services, audit-related services and tax services up to specified amounts, and sets requirements for specific case-by-case pre-approval of certain projects, those which may have a material effect on our operations or services over certain amounts. Pre-approval may be given as part of the Audit Committee’s approval of the scope of the engagement of our independent registered public accountants or on an individual basis. Any proposed services exceeding general pre-approved levels also require specific pre-approval by our Audit Committee. The pre-approval of services is sometimes delegated to one or more of the Audit Committee’s members, but the decision must be presented to the full Audit Committee at its next scheduled meeting. The policy prohibits retention of the independent public accountants to perform the prohibited non-audit services defined in Section 201 of the Sarbanes-Oxley Act or the rules of the Securities and Exchange Commission, and also considers whether proposed services are compatible with the independence of the registered public accountants.

ITEM 16E. PURCHASES OF EQUITY SECURITIES BY THE ISSUER AND AFFILIATED PURCHASERS

During the third quarter of 2007, we announced that our Board of Directors has authorized the repurchase of up to $30 million of our ordinary shares in the open market from time to time at prevailing market prices. The repurchase program received the approval of the District Court in Tel Aviv - Jaffa in November 2007 in accordance with the requirements of the Israeli Companies Law. As of December 31, 2010, we had repurchased 3,160,222 ordinary shares under the program at a total purchase price of approximately $23.4 million, or an average price of $7.42 per share, of which 351,179 ordinary shares were repurchased during 2007 at a total purchase price of approximately $4.0 million, or an average price of $11.49 per share, 1,627,304 ordinary shares were repurchased during 2008 at a total purchase price of approximately $11.1 million, or an average price of $6.84 per share and 204,833 ordinary shares were repurchased during 2009 at a total purchase price of approximately $1.1 million, or an average price of $5.57 per share. During 2010, no ordinary shares were repurchased in the open market under the repurchase program.

On September 7, 2010, we completed a self tender offer, under the repurchase program, to purchase 5.0% of our voting power, or 976,906 of our ordinary shares, for $7.30 per share, net to the seller in cash, less any required withholding taxes and without interest. We paid an aggregate of approximately $7.13 million for the tendered shares accepted for purchase.

ITEM 16G. CORPORATE GOVERNANCE

Under NASDAQ Listing Rule 5615(a)(3), foreign private issuers, such as our company, are permitted to follow certain home country corporate governance practices instead of certain provisions of the NASDAQ Listing Rules. A foreign private issuer that elects to follow a home country practice instead of any of such NASDAQ rules must submit to NASDAQ, in advance, a written statement from an independent counsel in such issuer’s home country certifying that the issuer’s practices are not prohibited by the home country’s laws.

On May 12, 2008, we provided NASDAQ with a notice of non-compliance with respect to the requirement to obtain shareholder approval for the establishment or amendment of certain equity based compensation plans, an issuance that will result in a change of control of the company, certain transactions other than a public offering involving issuances of a 20% or more interest in the company and certain acquisitions of the stock or assets of another company. Under Israeli law and practice, the approval of the board of directors is required for the establishment or amendment of equity based compensation plans. For the approvals and procedures required under Israeli law and practice for an issuance that will result in a change of control of the company, private placements and acquisitions of the stock or assets of another company, see in this Item 6.C. “Directors, Senior Management and Employee - Board Practices - Approval of Related Party Transactions Under Israeli Law-Disclosure of Personal Interests of a Controlling Shareholder; Approval of Transactions with Controlling Shareholders” and Item 10.B. “Additional Information -- Memorandum and Articles of Association - Provisions Restricting Change in Control of Our Company.”

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of

RADVISION LTD.

We have audited the accompanying consolidated balance sheets of RADVISION Ltd. ("the Company") and its subsidiaries as of December 31, 2009 and 2010, and the related consolidated statements of operations, changes in shareholders' equity and cash flows for each of the three years in the period ended December 31, 2010. Our audits also included the accompanying financial statement Schedule II listed in the Index in Item 18. These financial statements and schedule are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements and schedule based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the consolidated financial position of the Company and its subsidiaries as of December 31, 2009 and 2010, and the consolidated results of their operations and their cash flows for each of the three years in the period ended December 31, 2010, in conformity with U.S. generally accepted accounting principles. Also, in our opinion, the accompanying financial statement Schedule II listed in the Index in Item 18, when considered in relation to the basic financial statements taken as a whole, presents fairly, in all material respects, the information set forth therein.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the effectiveness of the Company's internal control over financial reporting as of December 31, 2010, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated May 11, 2011 expressed an unqualified opinion thereon.

As discussed in Note 2e to the consolidated financial statements, effective April 1, 2009, the Company changed its method of accounting for recognition and measurement of other-than-temporary losses on debt securities.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of

RADVISION LTD.

We have audited RADVISION Ltd.'s ("the Company") and its subsidiaries' internal control over financial reporting as of December 31, 2010, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission ("the COSO criteria"). The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, the Company and its subsidiaries maintained, in all material respects, effective internal control over financial reporting as of December 31, 2010, based on the COSO criteria.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of the Company and its subsidiaries as of December 31, 2009 and 2010, and the related consolidated statements of operations, changes in shareholders' equity and cash flows for each of the three years in the period ended December 31, 2010. Our audits also included the accompanying financial statement Schedule II listed in the Index in item 18. Our report dated May 11, 2011 expressed an unqualified opinion thereon.

NOTE 1:-

GENERAL

RADVISION Ltd. ("the Company") is an Israeli company which designs, develops and supplies products and technology that enable real-time voice, video and data communications over packet networks, including the Internet and other networks based on the Internet Protocol ("IP").

The Company's products and technology are used by its customers to develop systems that enable enterprises and service providers to use packet networks for real-time IP communications.

The Company operates under two reportable segments: 1) the Video Business Unit ("VBU") (formerly the Networking Business Unit ("NBU")), which develops a complete portfolio of video conferencing products, including video network infrastructure, desktop video solutions, conference room endpoint products and management software; and 2) the Technology Business Unit ("TBU"), which focuses on creating developer toolkits for the underlying IP communication protocols and testing tools needed for real-time voice and video over IP.

The Company has 12 wholly-owned subsidiaries: RADVISION Inc. and its wholly-owned subsidiary RADVISION Government Services, Inc. in the United States, RADVISION (HK) Ltd. in Hong Kong, RADVISION (UK) Ltd. in the United Kingdom, RADVISION FRANCE S.A.R.L. in France, RADVISION Japan KK in Japan, RADVISION B.V. in the Netherlands, RADVISION GmbH in Germany, RADVISION India Private Ltd. In India and RADVISION ESPAÑA, S.R.L. in Spain, all of which are primarily engaged in the sale and marketing of the Company's products and technology, and RADVISION Communication Development (Beijing) Co. Ltd. in China and RADVISION Italy S.r.l. in Italy, both of which are primarily engaged in research and development and the sale and marketing of the Company's products and technology.

Revenues derived from the Company's largest customer in 2008, 2009 and 2010 represented 39%, 42% and 34%, respectively, of total sales.

In April 2010, this customer acquired one of the Company's principal competitors. The Company's agreement with this customer is expected to continue through 2011. The Company anticipates that revenues from this customer will decrease significantly in 2011.

On February 10, 2010, the Company acquired certain assets of Aethra Video Srl and Aethra SpA of Ancona, Italy (together, "Aethra"), including certain intellectual property and technology for high definition ("HD") video conferencing endpoint systems. With this acquisition, the Company entered into the video conferencing endpoint market segment. The Company has had an original equipment manufacturer ("OEM") relationship with Aethra since 2005, through which the Company's video infrastructure products and technology have been included in Aethra video solutions, allowing Aethra to offer the market a complete end-to-end solution. The agreements for the acquisition were incorporated into Aethra's pre-insolvency plan that was filed and admitted by the Italian court on January 25, 2010.

GENERAL (Cont.)

The acquisition also includes the purchase of additional fixed assets and selected commercial agreements, which remains subject to the approval of the Italian court. The total transaction purchase price will be $ 9,586, which will also include the amount to be paid after the approval of the Italian court. As of December 31, 2010, the Company has paid $ 6,984 and accrued $ 1,575 which will be paid by the Company 18 months from December 31, 2009.

The total purchase price of Aethra is composed of the following:


Cash paid	$	6,984
Accrued payments		1,575

Total purchase price	$	8,559

Purchase Price Allocation:

In accordance with ASC 805, "Business Combinations," the total purchase price was allocated to the assets acquired and liabilities assumed based on their estimated fair values as set forth below as of the acquisition date. The excess of the purchase price over the net tangible and identifiable intangible assets was recorded as goodwill.

GENERAL (Cont.)

Intangible assets:

In performing the purchase price allocation, the Company considered, among other factors, the intention for future use of acquired assets, analyses of historical financial performance and estimates of future performance of Aethra's products. The fair value of intangible assets was based on a valuation completed by a third party valuation firm using the income approach and estimates and assumptions provided by management. The following table sets forth the components of intangible assets associated with the Aethra acquisition:

	Fair value		Useful life

Customer relationships (1)	$	1,680	4 years
Technology (2)		4,200	4 years
In-process research and development (3)		830	4 years (*)

Total intangible assets	$	6,710

(*)

In May 2010, upon completion of the development stage, the Company determined the useful life to be four years.

(1)

Customer relationships represent the underlying relationships and agreements with Aethra's installed customer base and will be amortized over a period of four years using the accelerated method.

(2)

Technology represents a combination of Aethra processes, patents and trade secrets related to the design and development of its products. This proprietary know-how can be leveraged to develop new technology and improve the Company's products. The technology is amortized over a period of four years using the straight line method.

(3)

In-process research and development ("IPR&D") represents incomplete Aethra research and development projects that had not reached technological feasibility and had no alternative future use as of the date of the acquisition. Upon completion of development, the acquired IPR&D will be considered finite-lived assets and will be amortized accordingly over four years.

The total acquisition related restructuring expenses, net of $ 2,722 consisted of certain labor related liabilities of Aethra's video department employees. Under Italian law, the Company assumed certain obligations towards these employees following the acquisition of certain Aethra assets in February 2010. These employees do not provide any service to the Company. Such employees are currently subject to the Italian Cassa Integrazione Guadagni Straordinaria ("CIGS") unemployment plan. Under the CIGS plan, such employees are entitled to unemployment benefits from the Italian government and we are required to pay monthly social security payments and severance payments. Under the terms of the CIGS plan, the Company recorded a provision in a total amount of $ 2,478 (see also Note 10).

Acquisition-related costs in the amount of $ 364 consisted mainly of legal and financial advisors fees. These costs were expensed in the current period and were included in the statements of operations in the line item "acquisition-related costs."

The pro forma information is not necessarily indicative of the results of operations, which actually would have occurred had the acquisition been consummated on that date, nor does it purport to represent the results of operations for future periods. For the purposes of the pro forma information, the Company has assumed that net loss includes additional amortization of intangible assets related to the acquisition of $ 1,785 and other acquisition-related expenses of $ 3,086 in 2009. The acquisition did not have a material effect on pro forma financial data for the period from January 1, 2010 to February 10, 2010.

SIGNIFICANT ACCOUNTING POLICIES

The consolidated financial statements are prepared according to generally accepted accounting principles in the United States ("U.S. GAAP").

Use of estimates:

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

Financial statements in U.S. dollars:

The Company's revenues are generated mainly in U.S. dollars ("dollar"). In addition, a significant portion of the costs of the Company and its subsidiaries is incurred in dollars. The Company's management believes that the dollar is the currency of the primary economic environment in which the Company and its subsidiaries operate. Thus, the functional and reporting currency of the Company and its subsidiaries is the dollar.

NOTE 2:-

SIGNIFICANT ACCOUNTING POLICIES (Cont.)

Accordingly, the Company's and its subsidiaries' transactions and balances denominated in dollars are presented at their original amounts. Non-dollar transactions and balances have been remeasured into dollars in accordance with ASC 830, "Foreign Currency Matters." Amounts in currencies other than U.S. dollars have been remeasured as follows:

Monetary balances - at the exchange rate in effect on the balance sheet date

Non monetary balances - at the exchange rates in effect as of the date of the transactions;

All exchange gains and losses from the remeasurement mentioned above are reflected in the statements of operations under financial income, net.

Principles of consolidation:

The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. Intercompany transactions and balances have been eliminated upon consolidation.

Cash and cash equivalents:

Cash and cash equivalents include short-term highly liquid investments that are readily convertible to cash with original maturities of three months or less at the date of purchase.

Marketable securities:

The Company accounts for investments in debt securities in accordance with ASC 320, "Investments - Debt and Equity Securities." Management determines the appropriate classification of its investments in debt securities at the time of purchase and reevaluates such determinations at each balance sheet date. As of December 31, 2009 and 2010, the Company classified its marketable securities (except for auction rate securities) as held-to-maturity securities and the auction rate securities as available-for-sale.

Securities classified as available-for-sale are stated at fair value, with unrealized gains and losses reported in accumulated other comprehensive income (loss) until realized, a separate component of shareholders' equity, net of taxes. Realized gains and losses on sales of investments, as determined on a specific identification basis, are included in the consolidated statements of operations.

The Company presented its available-for-sale securities in long-term investments (see Note 3b).

F - 14

RADVISION LTD. AND ITS SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 2:-

SIGNIFICANT ACCOUNTING POLICIES (Cont.)

Debt securities are classified as held-to-maturity since the Company has the intent and ability to hold these securities to maturity. These securities are stated at amortized cost and are therefore adjusted for amortization of premiums or accretion of discounts to maturity. Such amortization, accretion and interest on the debt securities are included in financial income, net.

On April 1, 2009, the Company adopted ASC 320, "Recognition and Presentation of Other-Than-Temporary Impairment." This guidance clarifies the interaction of the factors that should be considered when determining whether a debt security is other than temporarily impaired; provides guidance as to the amount of other-than-temporary impairment recognized in earnings and other comprehensive income; and expands the disclosures required for other-than-temporary impairments for debt and equity securities. The guidance requires an entity to assess whether it intends to sell, or it is more likely than not that it will be required to sell a security before recovery of its amortized cost basis. If either of those criteria is met, the entire difference between amortized cost and fair value is recognized in earnings. For securities that do not meet these criteria, the amount of impairment recognized in earnings is limited to the amount related to credit losses, while impairment related to other factors is recognized in other comprehensive income. The Company adopted this guidance on April 1, 2009, and reclassified $ 1,198 of the non-credit related portion of other-than-temporary impairment losses recognized in prior period earnings as a cumulative effect adjustment that increased retained earnings and decreased accumulated other comprehensive income at April 1, 2009. (See also Note 3b).

Short-term bank deposits:

Short-term bank deposits are deposits with maturities of more than three months but less than one year. The deposits are in dollars and bear interest at an annual weighted average rate of 1.50% and 1.36% at December 31, 2009 and 2010, respectively. The short-term deposits are presented at their cost, including accrued interest.

Inventories:

Inventories are stated at the lower of cost or market value.

Cost is determined as follows:

Raw materials - using the average cost method.

Finished products - using the average cost method.

NOTE 2:-

SIGNIFICANT ACCOUNTING POLICIES (Cont.)

Inventory write-offs and write-down provisions are recorded to cover risks arising from slow-moving items and/or technological obsolescence. The Company periodically evaluates the quantities on hand relative to historical and projected sales volume (which is determined based on an assumption of future demand and market conditions) and the age of the inventory. Based on this evaluation, provisions are made when required to write inventory down, recorded as part of cost of revenues in consolidated statement of operations. During the years ended December 31, 2008, 2009 and 2010, the Company wrote-off and wrote down slow-moving items and/or technological obsolescence in the amounts of $ 772, $ 304 and $ 350, respectively.

Property and equipment:

Property and equipment are stated at cost, net of accumulated depreciation. Depreciation is calculated using the straight-line method over the estimated useful lives of the assets, at the following annual rates:

	%

Computers and peripheral equipment	33
Office furniture and equipment	7 - 15
Motor vehicles	15
Leasehold improvements	Over the shorter of the term of the lease or useful lives

Goodwill and intangible assets:

Goodwill reflects the excess of the purchase price of a business acquired over the fair value of net assets acquired. Intangible assets consist of acquired technology, distribution network, customer relationships and IPR&D.

The Company follows the provisions of ASC 350, "Intangibles - Goodwill and Other" ("ASC 350"), according to which goodwill is not amortized but instead is tested for impairment at least annually (or more frequently if impairment indicators arise) at the reporting unit level. The reporting unit is described as an operating segment as that term is used in ASC 280, "Segment Reporting" ("ASC 280"), or one level below the operating segment. The Company has allocated all of its goodwill (including goodwill recorded as part of the Aethra acquisition) to the VBU reporting unit.

ASC 350 prescribes a two-phase process for impairment testing of goodwill.

NOTE 2:-

SIGNIFICANT ACCOUNTING POLICIES (Cont.)

In the first phase of impairment testing, goodwill attributable to each of the reporting units is tested for impairment by comparing the fair value of each reporting unit with its carrying value. For purpose of performing step one of the impairment test the Company estimated the fair value of the reporting unit according to the discounted cash flows (a present value technique). If the carrying value is less than the fair value, no impairment exists and the second step does not need to be completed. If the carrying value is higher than the fair value, there is an indication that impairment may exist, and a second step must be completed, to compute the amount of impairment. As of December 31, 2008, 2009 and 2010, no indication of impairment was identified. As a result, step two was not required.

Intangible assets are amortized over their useful lives using a method of amortization that reflects the pattern in which the economic benefits of the intangible assets are consumed or otherwise used up, in accordance with ASC 350. The Company amortizes its intangible assets on a straight-line basis, except for customer relationships (see also Note 1c and Note 2j).

Impairment of long-lived assets:

Long-lived assets are reviewed for impairment in accordance with ASC 360, "Property, Plant and Equipment" and ASC 205, "Presentation of Financial Statements" ("ASC 360" and "ASC 205," respectively), whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Impairment exists when the carrying value of the asset exceeds the aggregate undiscounted cash flows expected to be generated by the asset. The impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds their fair value. As of December 31, 2008, 2009 and 2010, no impairment losses were identified.

Severance pay:

The Company's liability for severance pay is calculated pursuant to Israel's Severance Pay Law based on the most recent salary of the employees multiplied by the number of years of employment, as of the balance sheet date. Employees are entitled to one month's salary for each year of employment or a portion thereof. The Company covers this liability by monthly deposits to insurance policies and by an accrual.

The value of these policies is recorded as an asset in the Company's balance sheet. The deposited funds include profits accumulated up to the balance sheet date. The deposited funds may be withdrawn only once an employee is entitled to severance pay pursuant to Israel's Severance Pay Law or labor agreements. The value of the deposited funds is based on the cash surrendered value of these policies and includes immaterial profits.

Severance pay expense for the years ended December 31, 2008, 2009 and 2010 amounted to approximately $ 1,933, $ 1,182 and $ 1,497, respectively.

Derivative instruments:

ASC 815, "Derivatives and Hedging" ("ASC 815"), requires companies to recognize all of their derivative instruments as either assets or liabilities in the balance sheet at fair value.

For derivative instruments that are designated and qualify as a cash flow hedge (i.e. hedging the exposure to variability in expected future cash flows that is attributable to a particular risk), the effective portion of the gain or loss on the derivative instrument is reported as a component of other comprehensive income (loss) and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. Any gain or loss on a derivative instrument in excess of the cumulative change in the present value of future cash flows of the hedged item is recognized in current earnings or losses during the period of change.

The Company entered into derivative instrument arrangements to hedge a portion of its anticipated New Israeli Shekel ("NIS") payroll payments. These derivative instruments are designated as cash flows hedges, as defined by ASC 815, as amended, and are highly effective. The Company measures the fair value of the contracts in accordance with ASC 820, "Fair Value Measurements and Disclosures" ("ASC 820") at Level 2. As of December 31, 2010, the Company had outstanding forward exchange contracts for the acquisition of NIS 89.2 million in consideration for $ 24,600 maturing in a period of up to one year. As of December 31, 2010, the Company recorded accumulated unrealized gain in accumulated other comprehensive income (loss) in the amount of $ 479 from its forward contracts with respect to anticipated payroll payments expected in 2011. Such amount is expected to be recorded in earnings in 2011.

For the years ended December 31, 2008, 2009 and 2010, the Company recognized earnings of $ 208, a loss of $ 155 and earnings of $ 389, respectively, as a result of these hedging activities. These hedge activities were recorded as part of cost of revenues, research and development, selling and marketing and general and administrative expenses in accordance with the classifications of payroll expenses as part of the consolidated statements of operations.

For the year ended December 31, 2010, the Company recorded a loss of $ 75 due to ineffectiveness of payroll hedging activities in financial income, net.

Revenue recognition:

The Company and its subsidiaries generate revenues mainly from: 1) sales of videoconferencing products, or VBU products; 2) licensing the rights to use their software products and royalty income, or TBU products; 3) maintenance and support, and 4) professional services. The Company and its subsidiaries sell their VBU products mainly through original equipment manufacturers, system integrators and value added resellers, all of whom are considered end-users.

Revenues from multiple element arrangements:

The Company accounts for its product and software licensing sales in accordance with ASC 985-605, "Software Revenue Recognition." ASC 985-605 generally requires revenue earned on software arrangements involving multiple elements to be allocated to each element based on the relative fair value of the elements. In addition, according to ASC 985-605, revenues should be allocated to the different elements in the arrangement under the "residual method" when vendor specific objective evidence ("VSOE") of fair value exists for all undelivered elements and no VSOE exists for the delivered elements. Under the residual method, at the outset of the arrangement with the customer, the Company defers revenue for the fair value of its undelivered elements (usually maintenance and support) and recognizes revenue for the remainder of the arrangement fee attributable to the elements initially delivered in the arrangement (software products) when all other criteria in ASC 985-605 have been met. Any discount in the arrangement is allocated to the delivered element.

The VSOE of fair value of the maintenance and support services is determined based on the price charged when sold separately (i.e. when renewed) and based on management's estimations.

In arrangements which include software, support/maintenance and services a determination is made whether the service element can be accounted for separately. In order for the service element to be accounted for separately (a) sufficient VSOE of fair value should exist to permit allocation of the revenue to the various elements of the arrangement (b) the services must not be essential to the functionality of any other element in the arrangement and (c) the service must be described in the contract such that the total price of the arrangement would be expected to vary as the result of the inclusion or exclusion of the services. If all such criteria are not met the Company accounts for the services together with the other elements in the arrangement as applicable.

Revenues from license fees and sales of products are recognized when persuasive evidence of an arrangement exists, delivery of the product has occurred, no significant obligations with regard to implementation remain, the fee is fixed or determinable and collectability is probable.

Maintenance and support revenue included is deferred and recognized on a straight-line basis over the term of the maintenance and support agreement.

Certain royalty agreements provide for per unit royalties to be paid to the Company based on the shipments by customers of units containing the Company's products. Revenues under such agreements are recognized at the time of delivery by customers, as they are reported to the Company by these customers, and when collectability is probable. Non-refundable payments on account of future royalties where no future obligation exists are recognized upon the signing of such arrangement and if collectability is probable.

Revenues from software licenses and sale of products that require significant customization, integration and installation are recognized based on ASC 605-35, "Construction-Type and Production-Type Contracts," according to which revenues are recognized on a percentage of completion basis. Percentage of completion is determined based on the "Output Method", upon completion of milestones, and when collectability is probable. After delivery of milestones, if uncertainty exists about customer acceptance, revenue is not recognized until acceptance. Provisions for estimated losses on uncompleted contracts are recognized in the period in which the likelihood of the losses is identified. As of December 31, 2009 and December 31, 2010, no such estimated losses were identified.

The Company believes that the use of the percentage of completion method is appropriate as the Company has the ability to make reasonably dependable estimates of the extent of progress towards completion, contract revenues and contract costs. In addition, contracts executed include provisions that clearly specify the enforceable rights regarding services to be provided and received by the parties to the contracts, the consideration to be exchanged and the manner and terms of settlement. In all cases, the Company expects to perform its contractual obligations and its licensees are expected to satisfy their obligations under the contract. According to ASC 605-35, costs that are incurred and are directly associated with a specific anticipated contract are being deferred, subject to evaluation of their probable recoverability, and recorded as unbilled contract costs.

Deferred revenue includes unearned amounts received under maintenance and support contracts, and amounts received from customers but not recognized as revenues due to the fact that these transactions did not meet the revenue recognition criteria.

The Company and its subsidiaries generally do not grant a right of return to their customers. In accordance with ASC 605, "Revenue Recognition," the Company records a provision for estimated product returns at the time product revenues are recognized based on the Company's historical experience. As of December 31, 2009 and 2010, the Company had a provision for product returns in the amount of $ 233 and $ 255, respectively.

Research and development costs:

Research and development costs are charged to the statements of operations as incurred. ASC 985, "Software", requires capitalization of certain software development costs subsequent to the establishment of technological feasibility.

Based on the Company's product development process, technological feasibility is established upon completion of a working model. Costs incurred by the Company between completion of the working models and the point at which the products are ready for general release has been insignificant. Therefore, all research and development costs have been expensed.

Income taxes:

The Company utilizes the liability method of accounting for income taxes as set forth in ASC 740, "Income Taxes." Under the liability method, deferred taxes are determined based on the temporary differences between the financial statement and tax basis of assets and liabilities using tax rates expected to be in effect during the years in which the basis differences reverse. A valuation allowance is recorded when it is more likely than not that the deferred tax assets will not be realized.

The Company applies ASC 740-10-55. ASC 740-10-55 contains a two-step approach to recognizing and measuring uncertain tax positions accounted for in accordance with ASC 740. The first step is to evaluate the tax position taken or expected to be taken in a tax return by determining if the weight of available evidence indicates that it is more likely than not that, on an evaluation of the technical merits, the tax position will be sustained on audit, including resolution of any related appeals or litigation processes. The second step is to measure the tax benefit as the largest amount that is more than 50% likely to be realized upon ultimate settlement. The Company accrues interest and penalties related to unrecognized tax benefits in its provision for income tax.

Fair value of financial instruments:

The carrying amounts of the Company's financial instruments, including cash and cash equivalents, short-term bank deposits, accounts receivable, trade payables and accrued expenses and other accounts payables, approximate fair value because of their generally short maturities.

The fair value of foreign currency contracts, (used for hedging purposes) (see 1 above) is estimated by obtaining current quotes from banks.

Fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or a liability. A three-tier fair value hierarchy is established as a basis for considering such assumptions and for inputs used in the valuation methodologies in measuring fair value:

Level 1

Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets.

Level 2

Include other inputs that are directly or indirectly observable in the marketplace.

Level 3

Unobservable inputs which are supported by little or no market activity.

The fair value hierarchy also requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value.

Warranty:

The Company typically offers a one-year warranty on all of its products. The specific terms and conditions of those warranties vary depending upon the product sold and country in which the Company does business. The Company estimates the costs that may be incurred under its basic warranty and records a liability in the amount of such costs at the time product revenue is recognized. Factors that affect the Company's warranty liability include the number of installed units, historical and anticipated rates of warranty claims, and cost per claim. The Company periodically assesses the adequacy of its recorded warranty liabilities and adjusts the amounts as necessary.

Liability for warranty expense is included in "Accrued expenses and other accounts payable" in the accompanying consolidated balance sheets. The roll forward of the liability for 2009 and 2010 was as follows:

	December 31,
	2009			2010

Balance, beginning of year	$	469		$	520
Additions to the accrual - costs of product revenue		536			865
Usage		(485	)		(686	)

Balance, end of year	$	520		$	699

Accounting for stock-based compensation:

The Company applies ASC 718, "Compensation - Stock Compensation" ("ASC 718"), which requires the measurement and recognition of compensation expense for all share-based payment awards made to employees and directors to be based on estimated fair values.

ASC 718 requires companies to estimate the fair value of share-based payment awards on the date of grant using an option-pricing model. The value of the portion of the award that is ultimately expected to vest is recognized as an expense over the requisite service periods in the Company's consolidated statements of operations.

The Company estimates option values using the Black-Scholes-Merton option pricing model that uses the weighted average assumptions noted in the table below. Expected volatility was calculated based upon actual historical stock price movements over a period equal to the expected term of the options. Estimated forfeitures are based on actual historical pre-vesting forfeitures. The Company derived the expected term assumption based on the provisions of SAB 110, which states that a company will determine its expected terms according to its historical exercise data for share option grants with sufficient exercise experience, except for options which were re-priced, for which the expected term of the options before the re-pricing was calculated using the binomial method.

The risk-free interest rate is based on the yield from U.S. treasury bonds with an equivalent term. The Company has historically not paid dividends and has no foreseeable plans to pay dividends, therefore estimated dividend yield is 0%. The Company recognized the compensation expense over the requisite service period using the straight-line method.

The fair value of the options granted in 2008, 2009 and 2010 was estimated at the date of grant with the following weighted average assumptions:

	Year ended December 31,
	2008			2009			2010

Risk free interest rate		3.06	%		1.76	%		1.39	%
Dividend yields		0	%		0	%		0	%
Volatility		39.2	%		45.6	%		49.5	%
Expected life (years)		3.37			3.55			4.13

The Company applies ASC 718 and ASC 505-50 with respect to options issued to non-employees which requires the use of option valuation models to measure the fair value of the options at the measurement date.

Concentration of credit risk:

Financial instruments that potentially subject the Company and its subsidiaries to concentrations of credit risk consist principally of cash and cash equivalents, marketable securities, short-term bank deposits, trade receivables and derivatives.

The majority of the Company's cash and cash equivalents, short-term bank deposits and derivatives are invested in dollar investments with major banks in Israel and the United States. Such cash and cash equivalents and short-term bank deposits in the United States may be in excess of insured limits and are not insured in other jurisdictions. However, management believes that the financial institutions that hold the Company's investments are institutions with high credit standing and accordingly, low credit risk exists with respect to these investments.

The marketable securities of the Company include investments in debentures of corporations, state and political subdivisions and auction rates securities. The Company's investment policy, approved by the Board of Directors, limits the amount that the Company may invest in any one type of investment or issuer, thereby reducing credit risk concentrations.

The trade receivables of the Company and its subsidiaries are derived from sales to organizations located mainly in North America, Europe, the Far East and Israel. The Company and its subsidiaries perform ongoing credit evaluations of their customers and to date have not experienced any material losses. An allowance for doubtful accounts is determined with respect to those amounts that the Company and its subsidiaries have determined to be doubtful of collection. In certain circumstances, the Company and its subsidiaries may require letters of credit, other collateral or additional guarantees. When uncertainty of collectability exists, the Company and its subsidiaries defer revenues until collection.

Basic and diluted net loss per share:

Basic net loss per share is computed based on the weighted average number of Ordinary shares outstanding during the year. Diluted net loss per share also includes the effect of dilutive stock options outstanding during the year, all in accordance with ASC 260, "Earning per Share."

The total weighted average number of shares related to the outstanding options excluded from the calculations of diluted net loss per share, since they would have an anti-dilutive effect, was 3,166,341 shares, 2,734,953 shares and 2,933,240 shares for 2008, 2009 and 2010, respectively.

Comprehensive income (loss):

The Company accounts for comprehensive income (loss) in accordance with ASC 220, "Comprehensive Income" ("ASC 220"). ASC 220 establishes standards for the reporting and display of comprehensive income (loss) and its components in a full set of general purpose financial statements. Comprehensive income (loss) generally represents all changes in shareholders' equity during the period except those resulting from investments by, or distributions to, shareholders.

The Company determined that its items of comprehensive income (loss) relate to unrealized gains and losses on hedging derivative instruments and unrealized gains and losses on available-for-sale securities.

Treasury shares:

The Company repurchases its Ordinary shares from time to time in the open market and holds such shares as treasury shares. The Company presents the cost to repurchase treasury shares as a reduction in shareholders' equity.

When treasury shares are reissued, the Company accounts for the re-issuance in accordance with ASC 505-30, "Treasury Stock" and charges the excess of the purchase cost over the re-issuance price (loss) to retained earnings. The purchase cost is calculated based on the weighted average method. In the event that the purchase cost is lower than the re-issuance price, the Company credits the difference to additional paid-in capital.

In October 2009, the FASB issued ASU No. 2009-13, "Multiple-Deliverable Revenue Arrangements (amendments to ASC Topic 605, Revenue Recognition)" ("ASU 2009-13"), and ASU No. 2009-14, "Certain Arrangements That Include Software Elements (amendments to ASC Topic 985, Software)" ("ASU 2009-14"). ASU 2009-13 requires entities to allocate revenue in an arrangement using estimated selling prices of the delivered goods and services based on a selling price hierarchy. The amendments eliminate the residual method of revenue allocation and require revenue to be allocated using the relative selling price method. ASU 2009-14 removes tangible products from the scope of software revenue guidance and provides guidance on determining whether software deliverables in an arrangement that includes a tangible product are covered by the scope of the software revenue guidance. As a result of the amendments included in ASU 2009-14, many tangible products and services that rely on software will be accounted for under the multiple-element arrangements revenue recognition guidance rather than under the software revenue recognition guidance. ASU 2009-14 also provides guidance on how to allocate transaction consideration when an arrangement contains both deliverables within the scope of software revenue guidance (software deliverables) and deliverables not within the scope of that guidance (non-software deliverables). ASU 2009-13 and ASU 2009-14 are to be applied on a prospective basis for revenue arrangements entered into or materially modified in fiscal years beginning on or after June 15, 2010. The Company adopted both standards for the fiscal year beginning January 1, 2011. The Company believes that the adoption of these amendments will not have a material impact on its consolidated financial statements.

In January 2010, the FASB issued ASU No. 2010-06, which amends ASC Topic 820-10, "Fair Value Measurements and Disclosures - Overall" ("ASC 820-10"). The update requires a gross presentation of activities within the Level 3 roll-forward and adds a new requirement to disclose transfers in and out of Level 1 and 2 measurements. The update further clarifies the existing disclosure requirements regarding: i) the level of disaggregation of fair value measurements; and ii) the disclosures regarding inputs and valuation techniques. The update was effective for the Company's fiscal year beginning January 1, 2010 except for the gross presentation of the Level 3 roll-forward information, which is effective for the Company's fiscal year beginning January 1, 2011. The principal impact from this update will be expanded disclosures regarding the Company's fair value measurements.

The amendment is effective prospectively for business combinations for which the acquisition date is on or after the beginning of the first annual reporting period beginning on or after December 15, 2010 (early adoption is permitted). The amendment clarifies the acquisition date that should be used for reporting the pro forma financial information disclosures when comparative financial statements are presented. The amendment also improves the usefulness of the pro forma revenue and earnings disclosures by requiring a description of the nature and amount of material, nonrecurring pro forma adjustments that are directly attributable to the business combination. The Company believes that the adoption of the amendment will not have a material impact on its consolidated financial statements.

In April 2010, the EITF issued ASU 2010-13, an amendment to ASC No. 718 "Compensation - Stock Compensation." The ASU clarifies employee stock options that have exercise prices denominated in the currency of any market in which a substantial portion of the entity's equity securities trade. These should be classified as equity, assuming all other criteria for equity classification are met. The amendments in the ASU do not contain any disclosure requirements incremental to those required by ASC 718. The guidance is effective for the Company's fiscal year beginning January 1, 2011. The adoption of the new guidance will not have a material impact on the Company's consolidated financial statements.

In February 2010, the FASB issued ASU 2010-09, an amendment to certain recognition and disclosure requirements of "Subsequent Events" codified in ASC 855, "Subsequent Events."

The Company's auction-rate securities, which have experienced a lack of liquidity and therefore do not have an active market of observable prices, are measured separately at fair value, which is determined using a valuation model. The valuation model relies on, among others things: (i) the underlying structure of each security; (ii) the present value of future principal and interest payments discounted at rates considered to reflect the uncertainty of current market conditions; (iii) consideration of the probabilities of default, auction failure or repurchase at par for each period; (iv) assessments of counterparty credit quality; (v) estimates of recovery rates in the event of default for each security; and (vi) overall capital market liquidity. These estimated fair values are subject to uncertainties that are difficult to predict.

DERIVATIVE INSTRUMENTS

Effective January 1, 2009, the Company adopted the disclosure requirements of ASC 815-10-15. The Standard requires additional disclosures about the Company's objectives and strategies for using derivative instruments, the accounting for the derivatives investments and the related hedged items and the effect of derivative instruments and related hedged items on the financial statements. The Company's risk management strategy includes the use of derivative instruments to reduce the volatility of earnings and cash flows associated with changes in foreign currency exchange rates. The Company does not enter into derivative transactions for trading purposes. The Company designated its derivatives as cash flow hedges. The Company recognizes all derivatives in the consolidated balance sheets at fair value. The Company enters into derivative contracts with major financial institutions in order to mitigate the credit risk in these transactions.

These contracts do not contain any credit-risk related contingent features. See Note 5 for information on the fair value of these contracts.

DERIVATIVE INSTRUMENTS (Cont.)

Cash flow hedges:

To protect against the increase in value of forecasted foreign currency cash flows resulting from salaries denominated in NIS during the year, the Company has instituted a foreign currency cash flow hedging program.

The Company hedges most of the anticipated payroll payments of its Israeli employees denominated in NIS for a period of one to 12 months with forward contracts. Accordingly, when the dollar appreciates against the NIS, the decline in present value of future foreign currency is offset by losses in the fair value of the hedging contracts. Conversely, when the dollar weakens, the increase in the present value of future foreign currency cash flows is offset by gains in the fair value of the hedging contracts.

These forward contracts are designated as cash flow hedges, and are all effective as hedges of these expenses. Accordingly, for derivative instruments that are designated and qualify as a cash flow hedge (i.e., hedging the exposure to variability in expected future cash flows that is attributable to a particular risk), the effective portion of the gain or loss on the derivative instrument is reported as a component of other comprehensive income and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. Any gain or loss on a derivative instrument in excess of the cumulative change in the present value of future cash flows of the hedged item is recognized in current earnings during the period of change.

Net unrealized gains on cash flow hedges as of December 31, 2009	$	162

Net unrealized gains on cash flow hedges as of December 31, 2010	$	479

NOTE 5:-

FAIR VALUE MEASUREMENTS

The Company measures its auction rate securities and foreign currency derivative contracts at fair value. Foreign currency derivative contracts are classified within Level 2 as the valuation inputs are based on quoted prices and market observable data of similar instruments.

Investments in auction rate securities are classified within Level 3 because they are valued using valuation techniques. The Company values the Level 3 investments based on an externally developed valuation by an independent valuation firm using discounted cash flow model, whose inputs include interest rate curves, credit spreads, bond prices, volatilities and illiquidity considerations. Unobservable inputs used in these models are significant to the fair value of the investments.

COMMITMENTS AND CONTINGENCIES

The Company received participation payments from the Israel U.S. Binational Industrial Research and Development Foundation ("BIRD-F") in the total amount of approximately $ 188. In return for the participation, the Company is committed to pay royalties at a rate of 2.5% of proceeds from the first year's sales and 5% of the proceeds from the succeeding years' sales, up to the amount of the grant. Once the amount of the grant has been repaid, royalties will be payable at the rate of 2.5% of proceeds, until royalties equal to one half of the grant amount have been repaid. The Company's total commitment for royalties payable with respect to future sales, based on BIRD-F participations received, net of royalties paid or accrued, totaled approximately $ 282 as of December 31, 2009 and 2010. During the years ended December 31, 2008, 2009 and 2010, the Company did not pay or accrue royalties to the BIRD-F.

The Company and its subsidiaries lease premises in Israel, the United States, China, Japan, the United Kingdom, France, Korea, Italy, Singapore, India and Hong Kong. The leases expire through March 2016 (some with renewal options). The Company also leases its motor vehicles under operating lease agreements that expire on various dates, the last of which is in 2013.

Annual minimum future lease payments due under the above agreements, at the exchange rate in effect on December 31, 2010, are approximately as follows:

2011	$	4,528
2012		3,635
2013		2,813

COMMITMENTS AND CONTINGENCIES (Cont.)

The Company obtained bank guarantees in the amount of $ 517 and $ 416, as of December 31, 2009 and 2010, respectively in connection with securing its office lease in Israel, in connection with custom tax payments and in connection with projects. In addition, the Company obtained $ 1,575 of bank guarantees as part of the Aethra acquisition (see also Note 1c).

The Company is committed to pay royalties to several third parties for the integration of these third parties' technologies into the Company's products. Royalties are generally payable based on the sales volume of these products as long as the Company uses these technologies.

The rates for the royalties to the third parties are based on an amount per product sold by the Company. The agreements pursuant to which the royalties are payable have no expiration dates.

The Company expensed royalties in the amount of $ 264, $ 224 and $ 216 in the years ended December 31, 2008, 2009 and 2010, respectively, in cost of revenues.

In 2003, a third party sent correspondence to the Company alleging that some products manufactured by the Company infringe upon patents held by this third party and offered to license these patents to the Company. Subsequent correspondence was exchanged during 2004, in which additional requests were made by this third party.

As of December 31, 2010, the Company has a provision of $ 1,191, which it believes covers the probable loss from such allegations.

During April 2009, the Company received a letter from one of its resellers, in which the reseller raised certain claims that the Company caused it damages due to, among other things, the cessation of the development of one of the Company’s products. In March, 2010 the reseller filed a claim against the Company in Germany and the court subsequently rendered a decision in the Company's favor. As of December 31, 2010, the period for filling an appeal has passed and no appeal was filed and therefore the Company reversed the provision it previously made. The Company has since received a letter from Israeli counsel to the reseller in which certain allegations and threats of potential litigation in Israel were made against the Company.

In September, 2010, the Company received a letter from a shareholder, addressed to the Chairman of its Board of Directors, in which certain allegations were made with respect to certain actions and alleged inactions of the Company, its directors and executive officers in connection with the self tender offer that the Company completed in September 2010. The Company has responded to the shareholder refuting all claims and denying any wrongdoings.

SHAREHOLDERS' EQUITY (Cont.)

In 2008, 2009 and 2010, the Company issued 5,000 shares, 81,500 shares and 33,475 shares, respectively, of the repurchased shares upon the exercise of employee stock options. The excess of the purchase price of the shares over their aggregate re-issuance price in the amount of $ 38, $ 458 and $ 162 was charged as a reduction to retained earnings for the years ended December 31, 2008, 2009 and 2010, respectively.

On November 25, 2008, the Company commenced a tender offer to eligible employees (other than its directors, Chief Executive Officer, Chief Financial Officer, president and senior officers who report to the Chief Executive Officer) to exchange outstanding options to purchase Ordinary shares issued under the Company's 2000 Employee Stock Option Plan ("the 2000 Plan") having an exercise price of $ 7.50 or more per share, for replacement options issued under the 2000 Plan that entitle the holder to purchase the same number of the Company's Ordinary shares at an exercise price equal to the greater of: (i) $ 7.50 per share, and (ii) the per share closing price of the Ordinary shares on the NASDAQ Global Market on the date the replacements options are granted. Pursuant to the exchange offer that expired on December 24, 2008, the Company accepted for exchange eligible options to purchase an aggregate of 1,276,950 Ordinary shares, with exercise prices ranging from $ 7.80-$ 28.0 per share, that had been granted under the 2000 Plan and granted new options to purchase an aggregate of 1,276,950 Ordinary shares, with an exercise price of $ 7.50 per share, under the 2000 Plan. The new options will vest over a period of up to four years and nine months in accordance with the vesting schedule described in the tender offer documents. The contractual term of the new options are six years except for cases when the original contractual term should be completed before the modified one.

The Company accounted for the exchange of options as a modification. A modification to the terms of an award should be treated as an exchange of the original award for a new award with total compensation cost equal to the grant-date fair value of the original award plus the incremental value measured at the same date. The calculation of the incremental value is based on the excess of the fair value of the new (modified) award based on current circumstances over the fair value of the original option measured immediately before its terms are modified based on current circumstances. That is, the original (pre-modification) option will be valued based on current assumptions, without regard to the assumptions made on the grant date. The modification date was considered to be December 24, 2008. As a result of the modification, the Company recorded incremental compensation cost of $ 581 to be recognized over the new service period beginning on the modification date. The unrecognized compensation cost remaining from the original grant date valuation is recognized over the remainder of the original requisite period. In its financial statements as of December 31, 2008, 2009 and 2010, the Company included an additional expense of $ 5, $ 142 and $ 140, respectively, with respect to this transaction.

SHAREHOLDERS' EQUITY (Cont.)

According to regulations adopted under the Israeli Companies Law, the terms of compensation of an outside director must be set and agreed to prior to the commencement of each three-year term of service of an outside director and may not be modified during the three year term other than to conform to the terms of a newly appointed outside director. During the second quarter of 2008, after receiving an opinion from the Company's legal advisors, the Company's Board of Directors cancelled options to purchase 117,500 Ordinary shares granted to two of its outside directors, due to certain terms of the aforementioned regulations which were not met. In the third quarter of 2008, the Company granted to each of its outside directors options to purchase 30,000 Ordinary shares, or in the aggregate options to purchase 90,000 Ordinary shares, exercisable at $ 6.78 per share. Options to purchase 60,000 Ordinary shares vested quarterly over three years, commencing May 14, 2006 (the date of the appointment of two of the directors as outside directors), and options to purchase 30,000 Ordinary shares vest quarterly over three years commencing September 24, 2008. The options are exercisable within 12 months after termination or resignation as a director of the Company. According to ASC 718, the option exchange was treated as a cancellation of the options and a grant of new options. Accordingly, in the financial statements for the year ended December 31, 2008, the Company recognized all the remaining compensation cost in the amount of $ 309 due to the cancellation of options. The fair value of the new options granted in the amount of $ 184 is recognized over the remaining vesting period. In 2008, 2009 and 2010, $ 111, $ 38 and $ 20 in compensation costs were recognized, respectively.

At the annual general meeting of shareholders held in October 2009, the Company's shareholders resolved to modify the terms of options granted to the Company's directors for his/her service in such capacity, such that the exercise period of such options (including previously granted options), be extended from 12 months to 18 months after a director's resignation from or termination of office. As a result of this modification, the Company recorded immaterial compensation expenses.

The Company currently has one employee option plan, which provides for the grant by the Company of options to purchase up to an aggregate of 7,996,316 Ordinary shares to officers, employees, directors and consultants of the Company and its subsidiaries at an exercise price equal to at least the fair market value at the date of grant. The options vest ratably over vesting periods of approximately four years. The options expire six to ten years from the date of grant.

As of December 31, 2010, 670,770 Ordinary shares are available for future issuance under the option plan. Options that are cancelled or forfeited become available for future grant.

Interest		50

Gross unrecognized tax benefits as of December 31 ,2010	$	1,179

The Company conducts business globally and, as a result, the Company or one or more of its subsidiaries file income tax returns in the U.S. federal jurisdiction and various state and foreign jurisdictions. In the normal course of business, the Company is subject to examination by tax authorities throughout the world, including such major jurisdictions as Israel and the United States. With few exceptions, the Company is no longer subject to U.S. federal, state and local, or non-U.S. income tax examinations for years prior to 2004 and is no longer subject to Israeli examinations for years prior to 2005.

TAXES ON INCOME (Cont.)

Israeli corporate tax structure:

Taxable income of Israeli companies is subject to tax at the rate of 27%, 26% and 25% in 2008, 2009 and 2010, respectively.

In July 2009, the Israeli Parliament passed the Law for Economic Efficiency (Amended Legislation for Implementing the Economic Plan for 2009 and 2010), 2009, which prescribes, among other things, an additional gradual reduction in the rates of the Israeli corporate tax and real capital gains tax starting 2011 to the following tax rates: 2011 - 24%, 2012 - 23%, 2013 - 22%, 2014 - 21%, 2015 - 20%, 2016 and thereafter - 18%.

Tax benefits under the Law for the Encouragement of Capital Investment, 1959 ("the Law"):

The Investment Law, prior to its amendment in April 2005, authorized the Israeli Investment Center to grant approved enterprise status ("Approved Enterprise") to capital investments in production facilities that meet certain relevant criteria specified by the law and the regulations specified thereafter. The tax benefits derived from any Approved Enterprise relate only to taxable income attributable to the specific program of investment to which the status was granted by the Investment Center.

On April 1, 2005, an amendment to the Investment Law came into effect ("the Amendment") that significantly changed the provisions of the Investment Law. The Amendment revised the criteria for investment programs qualified to receive tax benefits, which, if qualified, are referred to as a "Beneficiary Enterprise" (rather than the previous terminology of "Approved Enterprise"). The Amendment generally requires that at least 25% of the Beneficiary Enterprise's income be derived from export. Additionally, the Amendment enacted major changes in the manner in which tax benefits are awarded under the Investment Law so that companies no longer require Investment Center approval in order to qualify for tax benefits. However, the Investment Law provides that terms and benefits included in any letter of approval already granted to an Approved Enterprise will remain subject to the provisions of the law as they were on the date of such approval.

The Company has one capital investment program that has been granted Approved Enterprise status under the Investment Law ("the Approved programs") and two additional programs that qualify as Beneficiary Enterprises pursuant to the Amendment ("the Beneficiary programs"). One of the Beneficiary programs was converted from a previously Approved Enterprise program pursuant to the approval of the Israel Tax Authority that the Company received in October 2007. Pursuant to the Beneficiary and Approved programs, the Company is entitled to a tax benefit period of seven to 10 years on income derived from these programs, as follows: a full income tax exemption for the first two years and a reduced income tax rate of 10%-25% (instead of the regular rate of 27% 26% and 25% in 2008 2009 and 2010, respectively) for the remaining five to eight years depending on the level of foreign ownership of the Company.

TAXES ON INCOME (Cont.)

The duration of tax benefits detailed above for the Approved Enterprise is subject to limits of 12 years from the year of commencement of production, or 14 years from the date of granting the approval, whichever is earlier. The Company's Approved and Beneficiary programs expire between the years 2009 and 2017. The Company began using the tax benefits during the year 2006.

As of December 31, 2010, approximately $ 9,800 out of the Company's retained earnings are tax-exempt earnings attributable to its Approved Enterprise program and $ 12,700 are tax-exempt earnings attributable to its Beneficiary Enterprise program. The tax-exempt income attributable to the Approved and Beneficiary Enterprises cannot be distributed to shareholders without subjecting the Company to taxes. If these retained tax-exempt profits are distributed, the Company would be taxed at the corporate tax rate applicable to such profits as if the Company had not elected the alternative benefits track (as of December 31, 2010, this tax rate is 20%). According to the Amendment, tax-exempt income generated under the Beneficiary Enterprise will be taxed upon dividend distribution or complete liquidation, whereas tax exempt income generated under the Approved Enterprise will be taxed only upon dividend distribution (and not upon complete liquidation, where the tax liability will be incurred by the shareholders). As of December 31, 2010, if the income attributed to the Approved Enterprise was distributed as a dividend, the Company would incur a tax liability of approximately $ 2,450 at a rate of 20%, while if income attributed to the Beneficiary Enterprise was distributed as dividend, including upon liquidation, the Company would incur a tax liability in the amount of $ 3,193, also at a rate of 20%.

These amounts will be recorded as an income tax expense in the period in which the Company will declare the dividend or liquidates.

The Company's Board of Directors has determined that the Company will not distribute any amounts of its undistributed tax-exempt income as a dividend. The Company intends to reinvest its tax-exempt income. Accordingly, no deferred income taxes have been provided on income attributable to the Company's Approved and Beneficiary Enterprise programs, as the undistributed tax exempt income is essentially permanent in duration.

The benefits from the Company's Approved and Beneficiary Enterprise programs are dependent upon the Company fulfilling the conditions stipulated by the Law, the Amendment and the regulations published thereunder (as applicable), as well as the criteria in the approval for the specific investments in the Company's Approved Enterprise programs. If the Company does not comply with those conditions, the tax benefits may be canceled, and the Company may be required to refund the amount of the canceled benefits, with the addition of linkage differences and interest. As of the date of these financial statements, the Company's management believes that it has complied with these conditions.

NOTE 16:-

TAXES ON INCOME (Cont.)

By virtue of the Law, the Company is entitled to claim accelerated depreciation on equipment used by the Approved Enterprises during five tax years. The Company chose not to utilize this benefit in 2010. Income from sources other than the Approved and Beneficiary Enterprises during the benefit period will be subject to tax at Israel's regular corporate tax rate.

In December 2010, the Israeli Parliament passed the Law for Economic Policy for 2011 and 2012 (Amended Legislation), 2011, which prescribes, among other things, amendments to the Investment Law, effective as of January 1, 2011. According to the amendment, the benefit tracks under the Investment Law were modified and a uniform tax rate will apply to all of the income of an approved or beneficiary enterprise. Companies may elect to irrevocably implement the amendment (while waiving benefits provided under the Investment Law as currently in effect) and subsequently would be subject to the amended tax rates that are: 2011 and 2012 - 15%, 2013 and 2014 - 12.5% and in 2015 and thereafter - 12%. The Company is examining the possible effect of the amendment on the financial statements, if at all, and at this time has not yet decided whether to apply the amendment.

Dividends distributed from taxable income derived from an Approved Enterprise or Beneficiary Enterprise during the applicable benefits period would be subject to a 15% tax (or lower, if so provided under an applicable tax treaty), which would generally be withheld by the distributing company. While the Company may incur additional corporate tax liability in the event of distribution of dividends from tax exempt income generated from its Approved and Beneficiary Enterprises, no additional tax liability will be incurred by the Company in the event of distribution of dividends from income taxed in accordance with the 2011 Amendment.

Under the transitional provisions of the 2011 Amendment, the Company may elect whether to irrevocably implement the 2011 Amendment with respect to its existing Approved and Beneficiary Enterprises while waiving benefits provided under the legislation prior to the 2011 Amendment or may continue to implement the legislation prior to the 2011 Amendment during the next years.

Income taxes for non-Israeli subsidiaries:

Non-Israeli subsidiaries are taxed according to the tax laws in their respective country of residence.

Israeli income taxes and foreign withholding taxes were not provided for undistributed earnings of the Company's foreign subsidiaries. The Company's Board of Directors has determined that the Company will not distribute any amounts of its subsidiaries' undistributed earnings as a dividend. The Company intends to reinvest these earnings indefinitely in its foreign subsidiaries. Accordingly, no deferred income taxes have been provided. If these earnings were distributed to Israel in the form of dividends or otherwise, the Company would be subject to additional Israeli income taxes (subject to an adjustment for foreign tax credits) and foreign withholding taxes.

TAXES ON INCOME (Cont.)

The Company's U.S. subsidiary's carryforward tax losses through December 31, 2010, amounted to approximately $ 6,806. These losses may be offset against any future U.S. taxable income of the U.S. subsidiary and will expire in the years 2020 through 2026. Considering the Company's income projections, management concluded based on the weight of available evidence that it is more likely than not that the deferred tax asset associated with the net operating loss carryforward and the other deferred tax items will be partially utilized in coming years. See also f below for the deferred taxes and valuation allowance recorded in respect of carryforward losses.

Utilization of U.S. net operating losses may be subject to substantial annual limitations due to the "change in ownership" provisions of the Internal Revenue Code of 1986 and similar state provisions. The annual limitations may result in the expiration of net operating losses before utilization.

Deferred income taxes:

Deferred income taxes reflect the net tax effects of carryforward tax losses and temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and amounts used for income tax purposes. Significant components of the Company's deferred tax assets are as follows:

	December 31,
	2009			2010

Net operating loss carryforwards	$	1,804		$	1,057

TAXES ON INCOME (Cont.)

In assessing the realization of deferred tax assets, management considers whether it is more likely than not that all or some portion of the deferred tax assets will not be realized. The ultimate realization of the deferred tax assets is dependent upon the generation of future taxable income during the period in which temporary differences are deductible and net operating losses are utilized. Based on consideration of these factors, the Company recorded a valuation allowance amounting to $ 7,705 and $ 7,537 as of December 31, 2009 and 2010, respectively.

The Company's total income (loss) before provision for income taxes is as follows:
