D. Risk Factors

Investing in our ordinary shares involves a high degree of risk. You should consider carefully the risks described below, together with the financial and other information contained in this annual report, before deciding to invest in our ordinary shares. If any of the following risks actually occurs, our business, financial condition and results of operations would suffer. In this case, the trading price of our ordinary shares would likely decline and you might lose all or part of your investment. The risks described below are not the only ones we face. Additional risks that we currently do not know about or that we currently believe to be immaterial may also impair our business operations.

Risks Relating to Our Business

We have a history of losses, may incur future losses and may not achieve profitability.

We have incurred net losses in each fiscal year since we commenced operations in 1997 through 2009, other than 2006. We had a net loss of $7.7 million in 2009 of which $3.0 million resulted from a net impairment charge related to auction-rate securities, or ARS, compared to a net loss of $16.5 million in 2008 of which $7.7 million resulted from an impairment charge related to ARS and a net loss of $9.9 million in 2007 of which $4.9 million resulted from an impairment charge related to ARS. We can provide no assurance that we will be able to achieve profitability and we may incur losses in the next several years as we continue to expand our sales and marketing activities and to invest in research and development. We may also incur additional impairment charges related to ARS. We may incur losse s in the future and may not generate sufficient revenues in the future to achieve profitability.

We may be unable to compete effectively with other companies in our market who offer, or may in the future offer, competing technologies.

We compete in a rapidly evolving and highly competitive sector of the networking technology market. Our principal competitors are Cisco Systems, Inc. (through the acquisitions of P-Cube and Starent Networks, Corp.) and Sandvine Inc. in the service provider market, including the segment of the largest service providers, referred to as Tier 1 operators, and Blue Coat Systems, Inc. (through its acquisition of Packeteer Inc.) in the enterprise market. Our competitors have also identified the potential market opportunity of Tier 1 operators and we therefore expect intensive competition in this segment in the future. We also compete with a number of smaller competitors, such as CloudShield Technologies, Inc. and Procera Networks, Inc., and we compete indirectly with router and switch infrastructure companies w ith features that address some of the problems that our products address. We also face competition from companies that offer partial or alternative solutions addressing only one aspect of the challenges facing broadband providers, such as network monitoring or security. Our competitors may announce new products, services or enhancements that better meet the needs of customers or changing industry requirements, or may offer alternative methods to achieve customer objectives. One of our direct competitors, Cisco Systems, is substantially larger than we are and has significantly greater financial, sales and marketing, technical, manufacturing and other resources. The entry of new competitors into our market and acquisitions of our existing competitors by companies with significant resources and established relationships with our potential customers could result in increased competition and harm our business. Increased competition may cause price reductions, reduced gross margins and loss of market share, any of which could have a material adverse effect on our business, financial condition or result of operations.

If current unfavorable global economic conditions persist or worsen, our business, operating results and financial condition could be adversely effected.

The crisis in the financial and credit markets in the United States, Europe and Asia that began in 2008 has led to a global economic slowdown, with economies in those territories showing significant weakness. If the economies of any part of the world continue to be weak or further deteriorate, many enterprises, telecommunications carriers and service providers may reduce or postpone their capital investments significantly. This could result in reductions in sales of our products or services and longer sales cycles, slower adoption of new technologies and increased price competition. We continuously monitor market trends and intend to take such steps as we deem appropriate to adjust our operations, including measures to lower our expenditures. Since a substantial portion of our operating expenses consist of salaries, we may not be able to reduce our op erating expenses in line with any reduction in revenues or may elect not to do so for business reasons. We will need to continue to generate increased revenues and manage our costs to achieve profitability. If global economic and market conditions do not improve, or continue to deteriorate, it may lead to increase in our inventories, decrease our revenues, result in additional pressure on the price of our products, prolong payment terms, and increase the risk that we incur bad debts, each of which would have a material adverse effect on our results of operations and cash flow from operations.

The market for our products is still in its early stage and our growth may be harmed if Tier 1 operators and midsize service providers, do not adopt our solutions.

Our portfolio of hardware platforms and software applications uses our technology to transform broadband pipes into smart networks that can rapidly and efficiently deploy value added Internet services. We believe that the market for our technology is still in its early stage. We believe that the Tier 1 operators and midsize service providers, present a significant market opportunity and are an important element of our long term strategy. Nevertheless, they may decide that full visibility into their networks or highly granular control over content based applications is not critical to their business. They may also determine not to adopt the value added services we offer or that certain applications, such as VoIP or Internet video, can be adequately prioritized in their networks using router and switch infrastructure products without the use of our tech nology. They may also, in some instances, face regulatory constraints that could change the characteristics of the markets. They may also seek an embedded deep packet inspection, or DPI, solution in capital equipment devices such as routers rather than the stand-alone solution offered by us. Furthermore, widespread adoption of our products by Tier 1 operators and midsize service providers may require that they migrate to a new business model based on offering subscriber and application-based tiered services and market these new services successfully to consumers. If they decide not to adopt our technology, our market opportunity would be reduced and our growth rate may be harmed.

Demand for our products depends in part on the rate of adoption of bandwidth-intensive broadband applications, such as Internet video and online video gaming applications and applications highly sensitive to network delays such as voice over Internet protocol (VoIP).

Our products are used by service providers and enterprises to monitor and manage bandwidth-intensive applications that cause congestion in broadband networks and impact the quality of experience of users. Demand for our products is driven particularly by the growth in applications, which are highly sensitive to network delays and therefore require efficient network management. These applications include VoIP, Internet video and television and online video gaming applications. If the rapid growth in adoption of VoIP and in the popularity of Internet video and online video gaming applications does not continue, the demand for our products may not grow as anticipated.

Our revenues and business will be harmed if we do not keep pace with changes in broadband applications and with advances in technology.

We will need to invest heavily in developing our technology in order to keep pace with rapid changes in applications, increased broadband network speeds and with our competitors’ efforts to advance their technology. Designers of broadband applications that our products identify and manage are using increasingly sophisticated methods to avoid detection and management by network operators. Even if our products successfully identify a particular application, it is sometimes necessary to distinguish between different types of traffic belonging to a single application. Accordingly, we face significant challenges in ensuring that we identify new applications as they are introduced without impacting network performance, especially as networks become faster. This challenge is increased as we seek to expand sales of our products in new geographic territories because the applications vary from country to country and region to region. If we fail to address the needs of customers in particular geographic markets and if we fail to develop enhancements to our products in order to keep pace with advances in technology, our business and revenues will be adversely affected.

The network equipment market is subject to rapid technological progress and to compete we need to achieve widespread market acceptance.

The network equipment market is characterized by rapid technological progress, frequent new product introductions, changes in customer requirements and evolving industry standards. Developments in routers and routing software could also significantly reduce demand for and sales of our products, and cause our products to become obsolete, which may result in inventory write downs. Alternative technologies could achieve widespread market acceptance and displace the technology on which we have based our product architecture. We can give no assurance that our technological approach will achieve broad market acceptance or that other technology or devices will not supplant our products and technology.

Demand for our products may be impacted by government regulation of the telecommunications industry.

Carriers are subject to government regulation in a number of jurisdictions in which we sell our products. There are several proposals in the United States and Europe for regulating service providers’ ability to prioritize applications in their networks. Advocates for regulating this industry claim that collecting premium fees from certain “preferred” applications would distort the market for Internet applications in favor of larger and better-funded content providers and would impact end users who purchased broadband access only to experience differing response times in interacting with various content providers. Opponents believe that content providers who support bandwid th-intensive applications should be required to pay service providers a premium in order to support further network investments. The U.S. Federal Communications Commission held hearings to discuss “net neutrality,” which has been defined as service providers treating Internet content equally and not interfering with download speeds, regardless of the size or source of content. To date, the Federal Communications Commission has issued limited guidance on this issue and is currently reviewing it on a case-by-case basis. In August 2008, the Federal Communications Commission issued a ruling prohibiting Comcast, the second-largest broadband provider in the United States, from delaying some peer-to-peer traffic on its network. Comcast filed a court appeal in September 2008 seeking a review of such ruling. In April 2010, a federal appeals court ruled that the Federal Communications Commission had limited power over Web traffic under current law. This ruling could prompt efforts in Congress to amend the law in order to give the Federal Communications Commission explicit authority to regulate Internet service. Demand from carriers for the traffic management and subscriber management features of our products could be adversely affected if regulations prohibit, or limit, service providers from managing traffic on their networks. A decrease in demand for these features could adversely impact sales of our products.

We need to increase the functionality of our products and offer additional features and value added services in order to maintain or increase our profitability.

The market in which we operate is highly competitive and unless we continue to enhance the functionality of our products and add additional features, our competitiveness may be harmed and the average selling prices for our products will decrease over time. Such a decrease generally results from the introduction by competitors of competing products and from the standardization of DPI technology. To counter this trend, we endeavor to enhance our products by offering higher system speeds, and additional features and value added services, such as additional security functions, supporting additional applications and enhanced reporting tools. We may also need to reduce our per unit manufacturing costs at a rate equal to or faster than the rate at which selling prices decline. If we are unable to reduce these c osts or to offer increased functionally and features, our profitability may be adversely affected.

Under the current laws of some jurisdictions in which we operate, we may not be able to enforce employees’ covenants not to compete and therefore may be unable to prevent our competitors from benefiting from the expertise of some of our former employees.

It is our practice to have our employees sign appropriate non-compete agreements where permitted under applicable law. These agreements prohibit our employees, if they cease working for us, from competing directly with us or working for our competitors for a limited period. Under the current laws of some jurisdictions in which we operate, we may be unable to enforce these agreements and it may be difficult for us to restrict our competitors from gaining the expertise our former employees gained while working for us.

We may become dependent on one or more significant customers, and the loss of any such significant customer could harm our results of operations.

The loss of any significant customer or a significant decrease in business from any such customer could harm our results of operations and financial condition. In addition, revenues from individual customers may fluctuate from time to time based on the timing and the terms under which further orders are received and the duration of the delivery and implementation of such orders. During 2007 and 2008, no single customer accounted for more than 10% of our revenues. In 2009, we had a significant customer, which accounted for 15% of our revenues.

We depend on third parties to market, sell, install, and provide initial technical support for our products.

We depend on third party channel partners, such as distributors, resellers, OEMs and system integrators, to market and sell our products to end-customers. Our channel partners are also responsible for installing our products and providing initial customer support for them. As a result, we depend on the ability of our channel partners to market and sell our products successfully to end-customers. We also depend on our ability to maintain our relationships with existing channel partners and develop relationships in key markets with new channel partners. We cannot assure you that our channel partners will market our products effectively, receive and fulfill customer orders of our products on a timely basis or continue to devote the resources necessary to provide us with effective sales, marketing and techni cal support. In addition, any failure by our channel partners to provide adequate initial support to end-customers could result in customer dissatisfaction with us or our products, which could result in a loss of customers, harm our reputation and delay or limit market acceptance of our products. Our products are complex and it takes time for a new channel partner to gain experience in their operation and installation. Therefore, it may take a period of time before a new channel partner can successfully market, sell and support our products if an existing channel partner ceases to sell our products.

Our agreements with channel partners are generally not exclusive and our channel partners may market and sell products that compete with our products. Our agreements with our distributors and resellers are usually for an initial one-year term and following the expiration of this term, they can be terminated by either party. We can give no assurance that these agreements will not be terminated upon proper notice and any such termination may adversely affect our profitability and results of operations.

Sales of our products to large service providers can involve a lengthy sales cycle, which may impact the timing of our revenues and result in us expending significant resources without making any sales.

The length of our sales cycles to large service providers, including carriers, mobile operators and cable operators, is generally lengthy because these end-customers consider our products to be capital equipment and undertake significant testing to assess the performance of our products within their networks. As a result, we may invest significant time from initial contact with a large service provider until that end-customer decides to incorporate our products in its network. We may also expend significant resources attempting to persuade large service providers to incorporate our products into their networks without success. Even after deciding to purchase our products, initial network deployment of our products by a large service provider may last up to three years. If a competitor succeeds in convinc ing a large service provider to adopt that competitor’s product, it may be difficult for us to displace the competitor because of the cost, time, effort and perceived risk to network stability involved in changing solutions. As a result, we may incur significant expense without generating any sales.

We are dependent on our traffic management systems and network management application suites for the substantial majority of our revenues.

We currently derive the substantial majority of our revenues from sales of our NetEnforcer traffic management system, NetXplorer and Subscriber Management Platform (SMP) network management application suites, the Service Gateway platforms, and from maintenance and support contracts related to these products. In the past two years, we increased sales of our Service Gateway platforms, which combines a powerful DPI engine and array of services into a fully integrated, carrier-class platform. In addition, in 2009 we experienced increased demand for our SMP network management application suite. However, sales of our NetEnforcer traffic management system and NetXplorer network management system co ntinued to account for a significant portion of our revenues in 2009 and we currently expect these systems will continue to account for a significant portion of our revenues for the immediate future. As a result, any factor adversely affecting our ability to sell, or the pricing of or demand for, our NetEnforcer traffic management system and NetXplorer network management system would severely harm our ability to generate revenues.

We integrate various third-party solutions into, or together with, our products and may integrate or offer additional third-party solutions in the future. If we lose the right to use such solutions, our sales could be disrupted and we would have to spend additional capital to replace such components.

We integrate various third-party solutions into, or together with, our products and may integrate or offer additional third-party solutions in the future. Sales of our products could be disrupted if such third party solutions were either no longer available to us or no longer offered to us on commercially reasonable terms. In either case, we would be required to spend additional capital to either redesign our products to function with alternate third party solutions or develop substitute components ourselves. We might as a result be forced to limit the features available in our current or future product offerings.

Our products are highly technical, and any undetected software or hardware errors in our products could have a material adverse effect on our operating results.

Our products are complex and are incorporated into broadband networks which are a major source of revenue for service providers and which support critical applications for subscribers and enterprises. Due to the complexity of our products and variations among customers’ network environments, we may not detect product defects until full deployment in our customers’ networks. Regardless of whether warranty coverage exists for a product, we may be required to dedicate significant technical resources to resolve any defects. If we encounter significant product problems, we could experience, among other things, loss of major customers, cancellation of product orders, increased costs, delay in recognizing revenue, and damage to our reputation. In addition, we could face claims for product liability, tort, or breach of warranty. Defending a lawsuit, regardless of its merit, is costly and may divert management’s attention. In addition, if our business liability insurance is inadequate or future coverage is unavailable on acceptable terms or at all, our financial condition could be harmed.

The complexity and scope of the solutions and services we provide to larger service providers is increasing. Larger projects entail greater operational risk and an increased chance of failure.

The complexity and scope of the solutions and services we provide to larger service providers is increasing. The larger and more complex such projects are, the greater the operational risks associated with such projects. These risks include failure to fully integrate our products into the service provider’s network, with third party products and complex environments, and our dependence on subcontractors and partners for the successful and timely completion of such projects. Failure to complete a larger project successfully could expose us to potential contractual penalties, claims for breach of contract and in extreme cases, to cancellation of the entire project, or increase the likelihood we have difficulty in collecting payment and recognizing revenues.

We currently depend on a single subcontractor to manufacture and provide hardware warranty support for our legacy NetEnforcer traffic management systems and another subcontractor to provide similar services for our Service Gateway platforms and newer NetEnforcer traffic management systems. If either subcontractor experiences delays, disruptions, quality control problems or a loss in capacity, it could materially adversely affect our operating results.

We currently depend on a single subcontractor, R.H. Electronics Ltd., to manufacture, assemble, test, package and provide hardware warranty support for our legacy NetEnforcer AC-400, AC-800, AC-1000 and AC-2500 traffic management systems, and another subcontractor, Flextronics (Israel) Ltd., a subsidiary of Flextronics, a global electronics manufacturing, services company, to provide similar services for our Service Gateway platforms and our newer NetEnforcer AC-1400, AC-3000, AC-5000 and AC-10000 traffic management systems. In addition, our agreements with Flextronics (Israel) and R.H. Electronics require them to procure and store key components for our products at their facilities. If either of them experiences delays, disruptions or quality control problems in manufacturing our products, or if we fail to effectively manage the relationship with them, shipments of products to our customers may be delayed and our ability to deliver products to customers could be materially adversely affected. Our agreements with Flextronics (Israel) and R.H. Electronics are automatically renewed annually for additional one-year terms. R.H. Electronics may elect not to renew our agreement with them by giving us at least 90 days prior notice to the expiration of any such term. Furthermore, R.H. Electronics may terminate our agreement with them at any time during the term upon 120 days prior notice. Flextronics (Israel) may terminate our agreement at any time during the term upon 180 days prior notice. We expect that it would take approximately six months to transition manufacturing of our products to an alternate manufacturer and our inventory of completed products may not be sufficient for us to continue delivering products to our customers on a timely basis during any such transition. Therefore, the loss of either R.H. Ele ctronics or Flextronics (Israel) would adversely affect our sales and operating results, and harm our reputation.

The facilities of both R.H. Electronics and Flextronics (Israel) are located in northern Israel and are in range of rockets that were fired during 2006 from Lebanon into Israel. In the event that the facilities of either contractor are damaged as a result of hostile action, our ability to deliver products to customers could be materially adversely affected. See also “—Conditions in Israel could adversely affect our business, and —Our operations may be disrupted by the obligations of personnel to perform military service.”

Certain hardware components for our products come from single or limited sources, and we could lose sales if these sources fail to satisfy our supply requirements.

Certain hardware components used in our products are obtained from single or limited sources. Since our systems have been designed to incorporate these specific components, any change in these components due to an interruption in supply or our inability to obtain such components on a timely basis would require engineering changes to our products before we could incorporate substitute components. Such changes could be costly and result in lost sales. In particular, the central processing unit for our NetEnforcer AC-400 and our NetEnforcer AC-800 is from Intel Corporation, the network processor for our NetEnforcer AC-1000 and our NetEnforcer AC-2500 is from Hifn Inc., and the central pr ocessing unit for our Service Gateway platforms and our NetEnforcer AC-1400, AC-3000, AC-5000 and AC-10000 is from NetLogic Microsystems, Inc. (through the acquisition of Raza Microelectronics, Inc.). We do not have a supply agreement with Intel Corporation and the agreements with our other suppliers do not contain any minimum purchase or supply commitments.

If we or our contract manufacturer fail to obtain components in sufficient quantities when required, our business could be harmed. Our suppliers also sell products to our competitors. Our suppliers may enter into exclusive arrangements with our competitors, stop selling their products or components to us at commercially reasonable prices or refuse to sell their products or components to us at any price. Our inability to obtain sufficient quantities of single-source or limited-sourced components, or to develop alternative sources for components or products would harm our ability to maintain and expand our business.

If we fail to attract and retain skilled employees, we may not be able to timely develop, sell or support our products.

Our success depends in large part on the continued contribution of our research and development, sales and marketing and managerial personnel. If our business continues to grow, we will need to hire additional qualified research and development, sales and marketing and managerial personnel to succeed. The process of hiring, training and successfully integrating qualified personnel into our operation is a lengthy and expensive one. The market for qualified personnel is very competitive because of the limited number of people available with the necessary technical skills, sales skills and understanding of our products and technology. This is particularly true in Israel, where competition for qualified personnel is intense. Our failure to hire and retain qualified personnel could cause our revenues to decli ne and impair our ability to meet our research and development and sales objectives.

We may expand our business or enhance our technology through acquisitions that could result in diversion of resources and extra expenses. This could disrupt our business and adversely affect our financial condition.

Part of our strategy is to selectively pursue partnerships and acquisitions that provide us access to complementary technologies and accelerate our penetration into new markets. In 2008, we acquired the business of Esphion, a developer of network protection solutions for carriers and internet service providers, which increased the scope of our product offering. The negotiation of acquisitions, investments or joint ventures, as well as the integration of acquired or jointly developed businesses or technologies, could divert our management’s time and resources. Acquired businesses, technologies or joint ventures may not be successfully integrated with our products and operations. We may not realize the intended benefits of any acquisition, investment or joint venture and we may incur future losses fr om any acquisition, investment or joint venture.

In addition, acquisitions could result in:

substantial cash expenditures;

potentially dilutive issuances of equity securities;

the incurrence of debt and contingent liabilities;

a decrease in our profit margins; and

amortization of intangibles and potential impairment of goodwill.

If acquisitions disrupt our operations, our business may suffer.

Carriers, especially in North America, may condition a purchase of our products upon our receipt of a certification that such products meet the Network Equipment Building System (NEBS) requirements.

Carriers, especially in North America, often require that products they purchase meet Network Equipment Building System (NEBS) certification requirements, which relate the reliability of telecommunications equipment. Our Service Gateway platforms are designed to meet NEBS certification requirements, but carriers may not choose to use our systems until we receive the certification.

If we are unable to successfully protect the intellectual property embodied in our technology, our business could be harmed significantly.

Know-how relating to networking protocols, building carrier-grade systems and identifying applications is an important aspect of our intellectual property. To protect our know-how, we customarily require our employees, distributors, resellers, software testers and contractors to execute confidentiality agreements or agree to confidentiality undertakings when their relationship with us begins. Typically, our employment contracts also include the following clauses: assignment of intellectual property rights for all inventions developed by employees, non-disclosure of all confidential information, and non-compete clauses, which generally restrict the employee for six months following termination of employment. The enforceability of non-compete clauses in certain jurisdictions in which we operate may be limi ted. We cannot provide any assurance that the terms of these agreements are being observed and will be observed in the future. Because our product designs and software are stored electronically and thus are highly portable, we attempt to reduce the portability of our designs and software by physically protecting our servers through the use of closed networks, which prevent external access to our servers. We cannot be certain, however, that such protection will adequately deter individuals or groups from wrongful access to our technology. Monitoring unauthorized use of intellectual property is difficult, and some foreign laws do not protect proprietary rights to the same extent as the law of the United States. We cannot be certain that the steps we have taken to protect our proprietary information will be sufficient. In addition, to protect our intellectual property, we may become involved in litigation, which could result in substantial expenses, divert the attention of management, cause significant delays, materially disrupt the conduct of our business or adversely affect our revenue, financial condition and results of operations.

As of December 31, 2009, we had a limited patent portfolio. We had two issued U.S. patents and two pending U.S. patent applications. While we plan to protect our intellectual property with, among other things, patent protection, there can be no assurance that:

current or future U.S. or foreign patents applications will be approved;

our issued patents will protect our intellectual property and not be held invalid or unenforceable if challenged by third parties;

we will succeed in protecting our technology adequately in all key jurisdictions in which we or our competitors operate;

the patents of others will not have an adverse effect on our ability to do business; or

others will not independently develop similar or competing products or methods or design around any patents that may be issued to us.

The failure to obtain patents, inability to obtain patents with claims of a scope necessary to cover our technology, or the invalidation of our patents, may weaken our competitive position and may adversely affect our revenues.

We may be subject to claims of intellectual property infringement by third parties that, regardless of merit, could result in litigation and our business, operating results or financial condition could be materially adversely affected.

There can be no assurance that we will not receive communications from third parties asserting that our products and other intellectual property infringe, or may infringe their proprietary rights. We are not currently subject to any proceedings for infringement of patents or other intellectual property rights and are not aware of any parties that intend to pursue such claims against us. Any such claims, regardless of merit, could result in litigation, which could result in substantial expenses, divert the attention of management, cause significant delays and materially disrupt the conduct of our business. As a consequence of such claims, we could be required to pay a substantial damage award, develop non-infringing technology, enter into royalty-bearing licensing agreements, stop selling our products or re-brand our products. If it appears necessary, we may seek to license intellectual property that we are alleged to infringe. Such licensing agreements may not be available on terms acceptable to us or at all. Litigation is inherently uncertain and any adverse decision could result in a loss of our proprietary rights, subject us to significant liabilities, require us to seek licenses from others and otherwise negatively affect our business. In the event of a successful claim of infringement against us and our failure or inability to develop non-infringing technology or license the infringed or similar technology, our business, operating results or financial condition could be materially adversely affected.

We use certain “open source” software tools that may be subject to intellectual property infringement claims, the assertion of which could impair our product development plans, interfere with our ability to support our clients or require us to pay licensing fees.

Certain of our products contain open source code and we may use more open source code in the future. Open source code is code that is covered by a license agreement that permits the user to liberally copy, modify and distribute the software without cost, provided that users and modifiers abide by certain licensing requirements. The original developers of the open source code provide no warranties on such code.

As a result of our use of open source software, we could be subject to suits by parties claiming ownership of what we believe to be open source code and we may incur expenses in defending claims that we did not abide by the open source code license. If we are not successful in defending against such claims, we may be subject to monetary damages or be required to remove the open source code from our products. Such events could disrupt our operations and the sales of our products, which would negatively impact our revenues and cash flow. In addition, under certain conditions, the use of open source code to create derivative code may obligate us to make the resulting derivative code available to others at no cost. If we are required to publicly disclose the source code for such derivative products or to license our derivative products that use an open so urce license, our previously proprietary software products would be available to others, including our customers and competitors without charge.

We monitor our use of such open source code to avoid subjecting our products to conditions we do not intend. The use of such open source code, however, may ultimately subject some of our products to unintended conditions so that we are required to take remedial action that may divert resources away from our development efforts.

We have invested a substantial portion of our cash in auction-rate securities, or ARS, which subjects us to liquidity and investment risk. Due to uncertainties in the capital markets regarding auction-rate securities, we recorded impairment charges in 2007, 2008 and 2009, and, if the fair value of these investments were to decline further, we could be required to record further impairment charges related to these investments.

As of December 31, 2009, we had $27.9 million of principal invested in ARS, which consist of interests in collateralized debt obligations supported by pools of residential and commercial mortgages or credit cards, insurance securitizations and other structured credits, including corporate bonds. We determined the fair value of the ARS based on a third party valuation using a discounted cash flow model, the inputs and assumptions for which include the market conditions related to such security as well as the underlying structure of the security, the financial standing of the issuer, stated maturities, estimates of the probability of the issue being called at par prior to final maturity, estimates of the probability of defaults and recoveries, auctions failure and successful auction or repurchase at par for each period, expected changes in in terest rates paid on the securities, interest rates paid on similar instruments. Unobservable inputs and assumptions used in these models are significant to the fair value of the investments. In 2009, we recorded an impairment charge of $3.0 million resulting from further devaluation of our ARS portfolio. In addition, during 2009 we recorded an unrealized gain of $2.2 million to other comprehensive income in our balance sheet for appreciation of certain ARS in our portfolio. As of December 31, 2009, the fair value of the ARS on our balance sheet was $14.5 million. See “—Critical Accounting Policies and Estimates— Marketable Securities” below.

We cannot predict if or when the liquidity of these ARS will improve. We continue to monitor the market for ARS although there is currently a very limited secondary market for such securities. If these investments continue to experience further devaluation, we will record further impairment charges that could adversely affect our consolidated financial condition and results of operations. In addition, if the fair value of certain investments that have not experienced any devaluation were to decline, management would be required to evaluate whether such decline related to credit losses. The amount of any impairment loss which is determined to be credit loss would be immediately recorded in the consolidated statement of operations. Such an impairment charge could materially and adversely affect our consoli dated financial condition and results of operations. See Notes 2(g) and 4 to our consolidated financial statements for further information, including changes in the accounting treatment of ARS.

Our international operations expose us to the risk of fluctuation in currency exchange rates.

Our revenues are generated primarily in U.S. dollars and partially in euros and other currencies. A major portion of our expenses are denominated in U.S. dollars. As a result, we consider the U.S. dollar to be our functional currency. Other significant portion of our expenses are denominated in shekels and to a lesser extent in euros and other Asian currencies. Our shekel-denominated expenses consist principally of salaries and related personnel expenses. We anticipate that a material portion of our expenses will continue to be denominated in shekels. If the U.S. dollar weakens against the shekel or other currencies we are exposed to, there will be a negative impact on our results of operations. In addition, since a portion of our revenue is not incurred in dollars, therefore, fluctuations in exchange rates between the dollar and the currencies in whi ch such revenue is incurred may have a material effect on our results of operations and financial condition and if we wish to maintain the dollar-denominated value of our products in non-U.S. markets, devaluation in the local currencies of our customers relative to the U.S. dollar could cause our customers to cancel or decrease orders or default on payment. See “ITEM 11: Quantitative and Qualitative Disclosures about Market Risk.”

We may receive much lower interest income on our interest bearing investments due to changes in interest rates.

We have significant amount of cash that is currently invested primarily in interest bearing investments such as bank time deposits, money market funds, U.S. government treasury bills and ARS. These investments expose us to the changes in interest rates. If interest rates further decline, our results of operations may be adversely affected due to lower interest income from these investments.

Risks Related to Our Ordinary Shares

The share price of our ordinary shares has been and may continue to be volatile.

Our quarterly financial performance is likely to vary in the future, and may not meet our expectations or the expectations of analysts or investors, which may lead to additional volatility in our share price. The market price of our ordinary shares may be volatile and could fluctuate substantially due to many factors, including, but not limited, to:

announcements or introductions of technological innovations or new products, or product enhancements or pricing policies by us or our competitors;

disputes or other developments with respect to our or our competitors’ intellectual property rights;

announcements of strategic partnerships, joint ventures or other agreements by us or our competitors;

recruitment or departure of key personnel;

regulatory developments in the markets in which we sell our products;

our sale of ordinary shares or other securities in the future;

changes in the estimation of the future size and growth of our markets;

market conditions in our industry, the industries of our customers and the economy as a whole; or

implementation of a share buyback plan.

Share price fluctuations may be exaggerated if the trading volume of our ordinary shares is too low. The lack of a trading market may result in the loss of research coverage by securities analysts. Moreover, we cannot assure you that any securities analysts will initiate or maintain research coverage of our company and our ordinary shares. If our future quarterly operating results are below the expectations of securities analysts or investors, the price of our ordinary shares would likely decline. Securities class action litigation has often been brought against companies following periods of volatility. In April 2007, we announced that our revenue and earnings estimates for the first quarter of 2007 and that the 2007 fiscal year would be lower than previously projected. The closing price of our ordinary shares on the date following the announcement was $2.04, or 22%, lower than the closing price on the previous day. Subsequently, in May and June 2007, we and certain of our officers and directors were named as defendants in a number of purported securities class action lawsuits filed in the United States District Court for the Southern District of New York. See “ITEM 8: Financial Information—Consolidated Statements and Other Financial Information—Legal Proceedings.”

If we cannot meet NASDAQ’s continued listing requirements, NASDAQ may delist our ordinary shares, which would have an adverse impact on the liquidity and market price of our ordinary shares.

Our ordinary shares are currently listed on the NASDAQ Stock Market. Under NASDAQ rules, shares can be delisted and not allowed to trade on NASDAQ if the closing bid price of the stock over a 30 consecutive trading-day period is less than $1.00. If the price of our ordinary shares decline below the minimum listing requirement, it may be delisted from the NASDAQ Stock Market. A delisting of our ordinary shares could negatively impact us by reducing their liquidity and market price and the number of investors willing to hold or acquire our ordinary shares. This could negatively impact our ability to raise equity financing.

Our shareholders do not have the same protections afforded to shareholders of a U.S. listed company because we have elected to use an exemption available to foreign private issuers from certain NASDAQ corporate governance requirements.

As a foreign private issuer, we are permitted under NASDAQ Marketplace Rule 5615(a)(3) to follow Israeli corporate governance practices instead of the NASDAQ Stock Market requirements that apply to U.S. listed companies. As a condition to following Israeli corporate governance practices, we must disclose which requirements we are not following and the equivalent Israeli requirement. We must also provide NASDAQ with a letter from our outside counsel in our home country, Israel, certifying that our corporate governance practices are not prohibited by Israeli law. We rely on this “foreign private issuer exemption” with respect to the following two items: First, we follow the requirements of Israeli law with respect to the quorum requirement for meetings of our shareholders, which are different from the requirements of Ru le 5620(c). As a result, the quorum required for an ordinary meeting of shareholders consists of at least two shareholders present in person, by proxy or by written ballot, who hold or represent between them at least 25% of the voting power of our shares. Second, we follow Israeli law requirements with respect to the requirement to seek shareholder approval for equity compensation plans, which are significantly different the requirements of Rule 5635(c). Under Israeli law, we may amend our 2006 Incentive Compensation Plan by approval of our board of directors and without shareholder approval as is generally required under Rule 5635(c). As a result of these exemptions, our shareholders do not have the same protections as are afforded to shareholders of a U.S. listed company. We may in the future provide NASDAQ with an additional letter or letters notifying NASDAQ that we are following our home country practices, consistent with Israeli law and practices, in lieu of other requirements of Rule 5600.

Defending securities class action litigation requires extensive management attention and resources, and an unfavorable outcome could materially adversely affect our business, results of operations and financial condition.

Defending the purported securities class action lawsuits to which we are subject could be expensive, lengthy and disruptive to normal business operations, and could require extensive management attention and resources, regardless of the merit of these lawsuits. Moreover, we cannot predict the results of legal proceedings, and an unfavorable resolution of these lawsuits as a result of a settlement, or a court decision, could materially adversely affect our business, results of operations and financial condition.

A small number of significant beneficial owners of our shares acting together will have a significant influence over matters requiring shareholder approval, which could delay or prevent a change of control.

Our executive officers and directors and their affiliates beneficially own approximately 21.5% of our outstanding ordinary shares. As a result, these shareholders, acting together, could exercise significant influence over our operations and business strategy and will have sufficient voting power to influence the outcome of matters requiring shareholder approval.

These matters may include:

the composition of our board of directors which has the authority to direct our business and to appoint and remove our officers;

approving or rejecting a merger, consolidation or other business combination;

raising future capital; and

amending our articles of association which govern the rights attached to our ordinary shares.

This concentration of ownership of our ordinary shares could delay or prevent proxy contests, mergers, tender offers, open-market purchase programs or other purchases of our ordinary shares that might otherwise give you the opportunity to realize a premium over the then-prevailing market price of our ordinary shares. This concentration of ownership may also adversely affect our share price.

Future sales of our ordinary shares in the public market and low trading volume could adversely affect our share price.

As of December 31, 2009, we had 22,397,062 ordinary shares outstanding. Approximately 23.0% of these shares are “restricted securities” available for resale on the NASDAQ Stock Market subject, however, to volume limitations under Rule 144. Most of these restricted securities are held by the largest beneficial owners of our shares. Future sales of these restricted shares, or the perception that these sales could occur, could adversely affect the market price of our ordinary shares. We have experienced a low trading volume of our ordinary shares since our initial public offering and if one or a small number of parties buys or sells a large number of our ordinary shares, we may experience volatility in our share price and the price and liquidity of our shares may be a dversely affected.

Our U.S. shareholders may suffer adverse tax consequences if we are characterized as a passive foreign investment company

Generally, if for any taxable year 75% or more of our gross income is passive income, or the average percentage of our assets which produce passive income or which are held for the production of passive income (“passive assets”) is at least 50%, we would be characterized as a passive foreign investment company (“PFIC”) for U.S. federal income tax purposes for such taxable year. Publicly traded corporations must determine the percentage of assets on the basis of the value of their assets. No definitive guidance has been issued by the U.S. government concerning how to value the assets of a foreign public company for PFIC testing purposes. It can be inferred from the legislative history that the fair market value of the total assets of a publicly traded foreign corporation can be more easily measured, and is therefore likely to be less burdensome to taxpayers, by applying the “market capitalization” method. Under the market capitalization method, the total asset value of a company would be considered to equal the aggregate fair market value of its outstanding stock (i.e., its market capitalization) plus its outstanding liabilities, as of a relevant testing date. However, the legislative history did not specify the circumstances under which it would be appropriate to use the “market capitalization” method, or that such method was an exclusive means for valuing the total assets of a publicly traded corporation. Accordingly, if the market capitalization approach is found to be insufficient in the context of the facts and circumstances of a particular case, other reasonable valuation methods may be employed to determine the fair market value of a corporation's assets. In certain circumstances, including extremely volatile market conditions, it may be appropriate to apply alternative valuation methods, to more accurately determine the fair market value of our assets, such as a valuation of the assets by an independent qualified expert. We obtained an opinion from a U.S. tax advisor providing the reasoning for adoption of an approach other than the market capitalization approach and applying the results of our valuation study that was conducted by an independent valuator. In view of certain estimates of our gross income and the average value of our gross assets, the latter supported by said third party valuation and opinion, we believe that we should not be a PFIC for the taxable year ended December 31, 2009. There can be no certainty that the U.S. Internal Revenues Service (“IRS”) will not challenge such a position, however, and determine that based on the IRS’ interpretation of the asset test, we were a PFIC in 2009. Thus, there can be no assurance that we will not be considered a PFIC for 2009 or for any other taxable year. We are no t providing any U.S. tax opinion to any U.S. Holder concerning any potential PFIC status of our company, and U.S. Holders should consult their own tax advisors concerning the implication of the PFIC rules in his, her or its particular circumstances. See “ITEM 10: Taxation—United States Federal Income Taxation—Passive Foreign Investment Company Considerations.”

If we were characterized as a passive foreign investment company, a U.S. Holder (as defined under “ITEM 10: Additional Information—Taxation—United States Federal Income Taxation—Passive Foreign Investment Company Considerations”) could avoid certain adverse passive foreign investment company consequences by making a qualified electing fund election to be taxed currently on its proportionate share of the passive foreign investment company’s ordinary income and net capital gains. However, we do not intend to comply with the necessary accounting and record keeping requirements that would allow a U.S. Holder to make a qualified electing fund election with respect to the Company. See “ITEM 10: Additional Information—Taxation—United States Federal Income Taxation—Passive Forei gn Investment Company Considerations.”

Risks Relating to our Location in Israel

Conditions in Israel could adversely affect our business.

We are incorporated under Israeli law and our principal offices, and research and development facilities are located in Israel. Accordingly, political, economic and military conditions in Israel directly affect our business. Since the State of Israel was established in 1948, a number of armed conflicts have occurred between Israel and its Arab neighbors. In recent years, there has been an escalation in violence among Israel, Hamas, Hezbollah, the Palestinian Authority and other groups. Furthermore, several countries, principally in the Middle East, still restrict doing business with Israel and Israeli companies, and additional countries may impose restrictions on doing business with Israel and Israeli companies if hostilities in Israel continue or increase. These restrictions may limit materially our ability to sell our solutions to companies in these countries. Any hostilities involving Israel or 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 adversely affect our operations and product development, cause our revenues to decrease and adversely affect the share price of publicly traded companies having operations in Israel, such as us. Additionally, any hostilities involving Israel may have a material adverse effect on either of our principal subcontractors and their facilities in which event, all or a portion of our inventory may be damaged, and our ability to deliver products to customers may be materially adversely affected.

Our operations may be disrupted by the obligations of personnel to perform military service.

As of December 31, 2009, we employed 252 people, of whom 170 were based in Israel. Some of our executive officers and employees in Israel are obligated to perform annual military reserve duty in the Israel Defense Forces, depending on their age and position in the army. Additionally, they may be called to active reserve duty at any time under emergency circumstances 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 due to military service, and any significant disruption in our operations could harm our business. The full impact on our workforce or business if some of our executive officers and employees will be called upon to perform military service, especially in times of national emergency, is difficult to predict. Additionally, the absen ce of a significant number of the employees at either of our principal subcontractors related to military service may disrupt their operations in which event our ability to deliver products to customers may be materially adversely affected.

The tax benefits that are available to us require us to meet several conditions and may be terminated or reduced in the future, which would increase our costs and taxes.

Our investment program in equipment at our facility in Hod-Hasharon, Israel has been granted approved enterprise status and we are therefore eligible for tax benefits under the Israeli Law for the Encouragement of Capital Investments, 1959, referred to as the Investments Law. We expect to utilize these tax benefits after we utilize our net operating loss carry forwards. As of December 31, 2009, our net operating loss carry forwards for Israeli tax purposes amounted to approximately $46 million. To remain eligible for these tax benefits, we must continue to meet certain conditions stipulated in the Investments Law and its regulations and the criteria set forth in the specific certificate of approval, including, among other conditions, that the approved enterprise be operated ov er a seven-year period and that at least 30% of our investment in fixed assets of the approved enterprise be funded by additional paid-up ordinary share capital. If we do not meet the conditions stipulated in the Investments Law and its regulations and the criteria set forth in the specific certificate of approval in the future, the tax benefits would be canceled and we could be required to refund any tax benefits that we have received. These tax benefits may not be continued in the future at their current levels or at any level.

Effective April 1, 2005, the Investments Law was amended. As a result, the criteria for new investments qualified to receive tax benefits were revised. No assurance can be given that we will, in the future, be eligible to receive additional tax benefits under this law. The termination or reduction of these tax benefits would increase our tax liability in the future, which would reduce our profits or increase our losses. Additionally, if we increase our activities outside of Israel, for example, by future acquisitions, our increased activities might not be eligible for inclusion in Israeli tax benefit programs. See “ITEM 10: Additional Information—Taxation—Israeli Tax Considerations and Government Programs— ;Law for the Encouragement of Capital Investments, 1959.”

The government grants we have received for research and development expenditures restrict our ability to manufacture products and transfer technologies outside of Israel and require us to satisfy specified conditions. If we fail to comply with such restrictions or these conditions, we may be required to refund grants previously received together with interest and penalties, and may be subject to criminal charges.

We have received royalty-bearing grants from the government of Israel through the Office of the Chief Scientist of the Ministry of Industry, Trade and Labor, for the financing of a portion of our research and development expenditures in Israel, pursuant to the provisions of The Encouragement of Industrial Research and Development Law, 1984, referred to as the Research and Development Law. In 2007, 2008 and 2009, we received and accrued grants totaling $2.4, $2.7 and $2.4 million from the Office of the Chief Scientist, representing 20.2%, 18.3% and 20.8%, respectively, of our gross research and development expenditures in these periods. We may not receive future grants or may receive significantly smaller grants from the Office of the Chief Scientist and our failure to receive grants in the future could a dversely affect our profitability.

The terms of the grants prohibit us from manufacturing products outside of Israel or transferring intellectual property rights in technologies developed using these grants inside or outside of Israel without special approvals. Even if we receive approval to manufacture our products outside of Israel, we may be required to pay an increased total amount of royalties, which may be up to 300% of the grant amount plus interest, depending on the manufacturing volume that is performed outside of Israel. This restriction may impair our ability to outsource manufacturing or engage in similar arrangements for those products or technologies. Know-how developed under an approved research and development program may not be transferred to any third parties, except in certain circumstances and subject to prior approval . In addition, if we fail to comply with any of the conditions and restrictions imposed by the Research and Development Law or by the specific terms of under which we received the grants, we may be required to refund any grants previously received together with interest and penalties, and may be subject to criminal charges. In recent years, the government of Israel has accelerated the rate of repayment of the Office of Chief Scientist grants and may further accelerate them in the future.

It may be difficult to enforce a U.S. judgment against us, our officers and directors in Israel or the United States, or to assert U.S. securities laws claims in Israel or serve process on our officers and directors.

We are incorporated in Israel. The majority of our executive officers and directors are not residents of the United States, and the majority of our assets and the assets of these persons are located outside the United States. Therefore, it may be difficult for an investor, or any other person or entity, to enforce a U.S. court judgment based upon the civil liability provisions of the U.S. federal securities laws against us or any of these persons in a U.S. or Israeli court, or to effect service of process upon these persons in the United States. Additionally, it may be difficult for an investor, or any other person or entity, to assert U.S. securities law claims in original actions instituted in Israel. Israeli courts may refuse to hear a claim based on a violation of U.S. securities laws on the grounds that Israel is not the most appropriate forum in which to bring such a claim. Even if an Israeli court agrees to hear a claim, it may determine that Israeli law and not U.S. law is applicable to the claim. If U.S. law is found to be applicable, the content of applicable U.S. law must be proved as a fact which can be a time-consuming and costly process. Certain matters of procedure will also be governed by Israeli law. There is little binding case law in Israel addressing the matters described above.

Provisions of Israeli law and our articles of association may delay, prevent or make undesirable an acquisition of all or a significant portion of our shares or assets.

Our articles of association contain certain provisions that may delay or prevent a change of control, including a classified board of directors. In addition, Israeli corporate law regulates acquisitions of shares through tender offers and mergers, requires special approvals for transactions involving significant shareholders and regulates other matters that may be relevant to these types of transactions. These provisions of Israeli law could have the effect of delaying or preventing a change in control and may make it more difficult for a third party to acquire us, even if doing so would be beneficial to our shareholders, and may limit the price that investors may be willing to pay in the future for our ordinary shares. Furthermore, Israeli tax considerations may make potential transactions undesirable t o us or to some of our shareholders. See “ITEM 10: Additional Information—Memorandum of Association and Articles of Association—Anti-Takeover Measures” and “—Acquisitions under Israeli Law.”

If the price of our ordinary shares declines, we may be more vulnerable to an unsolicited or hostile acquisition bid.

Notwithstanding provisions of our articles of association and Israeli law, a decline in the price of our ordinary shares may result in us becoming subject to an unsolicited or hostile acquisition bid. In the event that such a bid is publicly disclosed, it may result in increased speculation regarding our company and volatility in our share price even if our board of directors decides not to pursue a transaction. If our board does wish to pursue a transaction, there can be no assurance that it will be consummated successfully or that the price paid will represent a premium above the original price paid for our shares by all of our shareholders. See “ITEM 10: Additional Information—Description of Share Capital—Anti-Takeover Measures” and “—Acquisitions under Israeli Law.”

B. Business Overview

Overview

We are a leading provider of intelligent IP service optimization solutions for mobile, DSL and wireless broadband carriers, cable operator service providers, and enterprises. Our portfolio of hardware platforms and software applications utilizes advanced deep packet inspection, or DPI, technology to transform broadband pipes into smart networks that can rapidly and efficiently manage data over mobile and wireline networks and deploy value added Internet services. Our scalable, carrier-grade solutions provide the visibility, security, application control and subscriber management that are vital to managing Internet service delivery, guaranteeing quality of experience, or QoE, containing operating costs, and maximizing revenue in broadband networks.

Industry Background

The rapid proliferation of broadband networks in recent years has been largely driven by demand from users for faster and more reliable access to the Internet and by the proliferation in the number and complexity of broadband applications, as well as the proliferation of mobile data-enhanced smart phones such as the iPhone.

Rising Network Operational Costs Due to the Rapid Adoption of Broadband Applications

The increasing adoption of broadband access has enabled significant advances in the sophistication of applications delivered over broadband networks. In contrast to traditional applications, such as e-mail and web-browsing, many newer applications, such as P2P, Internet video, online gaming and online content sites, require large amounts of bandwidth and are highly sensitive to network delays. In response to these challenges, service providers have been forced to invest heavily in network infrastructure upgrades and customer support services in order to maintain the quality of experience for subscribers.

Rising Data Traffic in Mobile Networks

The mobile data market is growing very rapidly, with the advent of the iPhone and other data-enhanced handsets, as well as the rise in use of mobile modems in laptop computers (“dongles”) and netbooks. To put this into perspective, the average smartphone user generates multiple times as much data traffic as the non-smartphone user.

The cost of deploying mobile bandwidth at the access point, or the GGSN, in mobile networks is significantly higher than that in wireline networks. As a result, mobile operators are already beginning to feel economic and infrastructure challenges in meeting the rising tide of data traffic over their networks. In addition, as capacity increases in mobile networks, smartphone users will have increased expectations with respect to speed and performance.

It is becoming increasingly apparent that unmanaged 3G, and even 4G mobile networks will not be able to cope with the rising tide of data traffic.

Service Providers Demand for the Ability to Offer Premium and Differentiated Services

Most service providers offer flat-fee broadband access, regardless of the type of applications and data used by subscribers. These operators provide the same level of service to all subscribers and do not guarantee access quality, regardless of a subscriber’s willingness to pay for premium services and network performance. In addition, competition among service providers has increased because of multiple broadband delivery options, such as cable, DSL, wireless and satellite. As a result of these factors, broadband access has become a commodity, contributing to downward price pressure and high churn rates.

To address these issues and increase the average revenue per user, or ARPU, service providers have begun to offer premium, differentiated services, such as improved quality for VoIP and Internet video. By offering such tiered services and charging subscribers according to the value of these services or according to accumulated usage, service providers can capitalize on the revenue enhancement opportunities enabled by broadband applications. To offer premium services and to guarantee service levels for those services, service providers need enhanced visibility into and control of network traffic, including visibility into the type of applications used on the network and levels of traff ic generated by different subscribers.

Increasing Enterprise Demand for Visibility and Delivery of Mission-Critical Applications

The proliferation of network applications also presents significant challenges for enterprises operating wide-area networks. Applications such as e-mail, customer relationship management, or CRM, enterprise resource planning and other online transactional and business applications are critical to enterprises’ ability to operate efficiently. Enterprises have also become increasingly dependent on broadband Internet and Intranet access, as content distribution between partners and customers, employee remote access, and even VoIP, have become more common. At the same time, the openness of the Internet allows employees to use a wide variety of recreational and non-business applications on enterprise networks, resulting in network congestion and negatively impacting employee productivity. As a result, en terprises have experienced diminished performance of their mission-critical applications.

Network Security Threats

As reliance on the Internet has grown, service providers and subscribers have become increasingly vulnerable to a wide range of security threats, including denial of service attacks. The attacks hinder the ability of service providers to provide high quality broadband access to subscribers, prevent enterprises from using mission-critical applications and compromise network and data integrity. We believe that users increasingly expect service providers to protect them from these threats. Therefore, it has become imperative for service providers and enterprises to identify and block malicious traffic at very early stages.

The Challenge of Implementing Intelligent Networks

Service providers are seeking to transform generic access broadband networks into intelligent broadband networks. The ability to identify, distinguish and prioritize different applications plays a major role in intelligent network management, allowing service providers to optimize bandwidth usage and reduce operational costs, while maintaining high quality of service. Application designers are employing increasingly sophisticated methods to avoid detection by network operators who desire to manage network use. Traditional network infrastructure devices, such as routers and switches, do not generally have sufficient computing resources or the required algorithms to distinguish between different and rapidly evolving applications. The dilemma of implementing intelligent networks is further complicated by to day’s higher speed broadband networks, which carry tremendous amounts of data and serve millions of customers. Unlike traditional network infrastructure devices, such as switches and routers, which can perform only a very limited examination of packets, DPI solutions offer active management of each application and subscriber in the network requiring significant processing power and speed, greater memory and special algorithms.

The Allot Solution

Our solutions enable service providers to optimize and monetize their wireline and mobile data networks. These solutions employ advanced deep packet inspection, or DPI, which identifies applications by examining the content encapsulated in packets, including header and application information. By correlating data from multiple packets and flows, searching for application signatures and recognizing application behavior, our solutions identify each subscriber and application in the network and provide in-depth, real time information about their behavior. Once an application has been identified, it can be managed using predetermined policies that determine the level of network resources allocated for that application based on the business strategy of the service provider or enterprise. We have developed market-leading DPI technology that accurately identifies hundreds of application protocols at higher speeds and creates customized detailed usage analyses and reports. Our vision is that our technology will become a platform for a range of value-added services, rather than an added feature on a router. Once our DPI engine is able to provide information regarding applications running over the network, we believe our platform will enable service providers to use this information to drive additional revenues by enabling additional functionalities on our DPI platform. In 2008, we acquired the business of Esphion, a developer of network protection solutions for carriers and internet service providers, which increased the scope of our product offering. In 2009, we announced the Allot MediaSwift, a solution designed to save backhaul cost to service providers and to enhance QoE to end users by caching and accelerating popular internet video, and the Allot WebSafe, a network service designed to block access to illegal websites defined by the Internet Watch Foundation (IWF).

Our Products

Traffic Management Systems

Our traffic management systems consist of the Service Gateway platform and the NetEnforcer product line.

The Service Gateway platform is an open standards-based platform for broadband service control and optimization based on DPI. It is based on an AdvancedTCA®-compliant chassis with modular, hot-swappable DPI blades. A single platform provides up to 16 Gigabit Ethernet ports or eight 10 Gigabit Ethernet ports, supporting up to 60 Gigabits per second (Gbps) of throughput. Within the Service Gateway, the application and subscriber information for each traffic flow is identified by a single DPI process that can then dispatch the flow to an array of additional services and actions. These actions may, through additional blades on the platform, include traffic prioritization and Quality of Service, or QoS, optimization, filtering (including parental control), blocking security threats (Clean Line and denial-of-service-prevention), media caching or collec ting records for real-time charging or offline usage-based charging.

The Service Gateway is designed to reduce the cost and complexity of developing new services. It increases operation efficiency by enabling service providers to deploy multiple services through a single multi-purpose platform rather than by using multiple single purpose appliances. Using the Service Gateway, service providers are able to manage all services using the same policy control rules and management application. The Service Gateway enables providers to minimize the number of packets handled by each application for all services by leveraging a single DPI process.

The Service Gateway platform also leverages our powerful NetXplorer centralized management software and is fully integrated with our Subscriber Management Platform, described below.

Our NetEnforcer traffic management system inspects, monitors and controls network traffic by application and by user. NetEnforcer devices are positioned at multiple strategic network locations where the most traffic traverses and can be monitored and managed. These locations include network access points, or “peering points,” where the network connects to other networks and data centers. NetEnforcer includes its own management software and can also be managed by other vendor management applications through an interface that integrates with the end-customer’s operating environment. These applications include policy servers, provisioning systems, customer care and billing applications.

Our traffic management devices are available in several different models to address the needs of a wide range of service providers and enterprises:

Series	Target Market	Operation Speeds	Subscribers(1)
NetEnforcer AC-400	Small to medium enterprise networks and service provider networks	Up to 200 Mbps	Up to 4,000
NetEnforcer AC-800	Medium and large enterprise networks and medium service provider networks	Up to 620 Mbps	Up to 28,000
NetEnforcer AC-1000/ AC-2500	Carrier-class solutions used by medium and large service provider networks	Up to 2 Gbps and 5 Gbps, respectively	Up to 80,000
NetEnforcer AC-1400/ AC-3000	Carrier-class solutions used by large enterprise networks and medium and large service provider networks	Up to 2 Gbps and 8 Gbps, respectively	160,000
NetEnforcer AC-5000	Carrier-class solutions used by medium and large service provider networks with 1G and 10GE networks	Up to 15 Gbps	400,000
NetEnforcer AC-10000	Carrier-class solutions used by medium and large service provider networks with 1G and 10GE networks	Up to 30 Gbps	Up to 800,000
Service Gateway – Omega/Sigma	Carrier-class solutions used by medium and large service provider networks	Up to 60 Gbps	Up to 2,000,000

(1)	Represents the maximum number of subscribers that a system can handle simultaneously. Typically, due to network topology, redundancy requirements and other constraints, such as total bandwidth available per subscriber, the actual number per product unit is lower

Our Service Gateway platforms are designed to meet NEBS Level 3 certification requirements to ensure operation in extreme environmental conditions.

Network Management Application Suites

Our network management application suites consist of the NetXplorer management application and the Subscriber Management Platform.

The NetXplorer management application suite provides service providers and enterprise customers a highly granular, real time view of all traffic on the network. This centralized management suite, works in conjunction with our Service Gateway and NetEnforcer products to provide network traffic intelligence and enable enterprises and service providers to effectively manage broadband services and set policies for the use of their networks. The data provided from multiple systems are aggregated, analyzed and conveyed using our NetXplorer management application suite.

NetXplorer architecture consists of four elements: first, the client element is the NetXplorer graphical user interface application; second, the server element consisting of the actual NetXplorer application, including the database; third, the optional collector element, which assists in collecting large amounts of data from multiple Service Gateways or NetEnforcers; and fourth, an agent element that is an add-on to the Service Gateway or the NetEnforcer that enables them to be managed by the NetXplorer and support all network management functions.

Our Subscriber Management Platform, or SMP, is a scalable system that helps service providers build an intelligent service network designed to deliver the QoE that each subscriber expects, while allowing providers to manage network usage. The SMP monitors subscriber behavior to identify, track and report short- or long-term usage trends. Behavior can be tracked on an individual basis or for groups of subscribers. By analyzing these trends, providers can know which services are the most popular and with whom. This allows the provider to quickly roll out new or packaged services based on individual subscriber demand and preferred delivery. The SMP supports per-subscriber QoS policy definition, enabling providers to rapidly create and deploy tiered service plans that allow different subscribers to have diff erent quality parameters on a per-service basis. This capability, together with the SMP’s tiered services control and quota management features, create an opportunity for innovative service packaging and pricing based on individual subscriber demand and preferred delivery. This flexible and customized delivery helps service providers increase ARPU, reduce churn and facilitate the introduction of new revenue-generating services without service interruption.

The solution is a network service designed to block access to illegal websites defined by the Internet Watch Foundation (IWF). At the same time, it allows operators to comply with emerging legislation surrounding online child sexual abuse images and other illegal content. WebSafe is offered as an integrated service within our Service Gateway and it is also offered as a solution with other Allot platforms.

Customers

We have a global, diversified end-customer base consisting primarily of service providers and enterprises. Our direct customers are generally distributors, resellers, OEMs and system integrators, who we refer to as our channel partners. In 2009, we derived 52% of our revenues from Europe, the Middle East and Africa, 26% from Asia and Oceania and 22% from the Americas. We generally only have direct contact with end-customers in the case of larger projects, as smaller projects are driven by our channel partners. In 2009, we had a significant customer which accounted for 15% of our revenues.

Channel Partners

We market and sell our products to end-customers both by direct sales and through our channel partners, which include distributors, resellers, OEMs and system integrators. Our channel partners generally purchase our products from us upon receiving orders from end-customers and are responsible for installing and providing initial customer support for our products. Our channel partners are located around the world and address most major markets. Our channel partners target a range of end-users, including carriers, alternative carriers, cable operators, private networks, data centers and enterprises in a wide range of industries, including government, financial institutions and education. Our agreements with channel partners that are distributors or resellers are generally non-exclusive and are for an initi al term of one year and automatically renew for successive one-year terms unless terminated. After the first year, such agreements may be terminated by either party upon ninety days prior notice.

We offer support to our channel partners. This support includes the generation of leads through marketing events, seminars and web-based leads and incentive programs as well as technical and sales training.

Our sales staff’s direct contact with end-customers consists mainly of developing leads for our channel partners. A vast majority of our sales occur through our channel partners.

Sales and Marketing

The sales and deployment cycle for our products varies based upon the intended use by the end-customer. The sales cycle for initial network deployment may generally last between one and three years for large and medium service providers, six to twelve months for small service providers, and one to six months for enterprises. Follow-on orders and additional deployment of our products usually require shorter cycles. Large and medium service providers generally take longer to plan the integration of our solutions into their existing networks and to set goals for the implementation of the technology.

We focus our marketing efforts on product positioning, increasing brand awareness, communicating product advantages and generating qualified leads for our sales organization. We rely on a variety of marketing communications channels, including our website, trade shows, industry research and professional publications, the press and special events to gain wider market exposure.

We have organized our worldwide sales efforts into the following three territories: North and South America, Europe the Middle East and Africa, and Asia and Oceania. We have regional offices in the U.S., Israel, France, Spain, United Kingdom, Singapore, Japan and China, and a dedicated regional presence in Germany, Italy, the Czech Republic, India, Hong Kong and Australia. We also maintain a regional presence in Mexico and Brazil.

As of December 31, 2009, our sales and marketing staff, including product management and business development functions, consisted of 57 employees.

Service and Technical Support

We believe our technical support and professional services capabilities are a key element of our sales strategy. Our technical staff assists in presales activities and advises channel partners on the integration of our solutions into end-user networks. Our basic warranty extended to end-customers through our channel partners is three months for software and twelve months for hardware. Generally, end-customers are also offered, through our channel partners, a choice of one year or three-year customer support programs when they purchase our products. These customer support programs can be renewed at the end of their terms. Our end-customer support plans offer the following features:

expedited replacement units in the event of a warranty claim; and

software updates and upgrades offering new features and addressing new network applications.

Our channel partner support plans are designed to maximize network up-time and minimize operating costs. Our channel partners and their end-customers are entitled to take advantage of our around-the-clock technical support which we provide through our four help desks, located in France, Israel, Singapore and the United States. We also offer our channel partners 24-hour access to an external web-based technical knowledge base, which provides technical support information and enables them to support their customers independently and obtain follow up and support from us. We manage our channel partner and customer support efforts through a single database which enables us to track seamlessly any response provided to a channel partner or end-customer from a different office and to escalate automatically any c ustomer inquiry after a predetermined period of time.

The expenditures associated with the technical support staff are allocated in our statements of operations between sale and marketing expenses and cost of goods sold based on the roles of and tasks performed by personnel.

As of December 31, 2009, our technical staff consisted of 57 employees.

Research and Development

Our research and development activities take place in Israel and New Zealand. As of December 31, 2009, 92 of our employees were engaged primarily in research and development. We devote a significant amount of our resources towards research and development to introduce and continuously enhance products to support our growth strategy. We have assembled a core team of experienced engineers, many of whom are leaders in their particular field or discipline and have technical degrees from top universities and experience working for leading Israeli networking companies. These engineers are involved in advancing our core technologies, as well as in applying these core technologies to our product development activities. Our research and development efforts have benefited from royalty-bearing grants from the Offic e of the Chief Scientist. The State of Israel does not own any proprietary rights in technology developed with the Office of the Chief Scientist funding and there is no restriction related to the Office of the Chief Scientist on the export of products manufactured using technology developed with Office of the Chief Scientist funding. For a description of restrictions on the transfer of the technology and with respect to manufacturing rights, please see “ITEM 3: Key Information—Risk Factors—The government grants we have received for research and development expenditures restrict our ability to manufacture products and transfer technologies outside of Israel and require us to satisfy specified conditions. If we fail to comply with such restrictions or these conditions, we may be required to refund grants previously received together with interest and penalties, and may be subject to criminal charges.”

Manufacturing

We subcontract the manufacture and repair of our legacy NetEnforcer products (AC-400, AC-800, AC-1000 and AC-2500) to R.H. Electronics, an Israeli manufacturer and manufacture and repair of our Service Gateway platforms and our newer NetEnforcer products (AC-1400, AC-3000, AC-5000 and AC-10000) to Flextronics (Israel) Ltd., a subsidiary of Flextronics, a global electronics manufacturing services company. This strategy enables us to reduce our fixed costs, focus on our core research and development competencies and provide flexibility in meeting market demand. R.H. Electronics and Flextronics (Israel) are contractually obligated to provide us with manufacturing services based on agreed specifications, including manufacturing, assembling, testing, packaging and procuring the raw materials for our devices. We are not required to provide any minimum orders. Our agreement with each contractor is automatically renewed annually for additional one-year terms. R.H. Electronics may elect not to renew our agreement with them by giving us at least 90 days prior notice to the expiration of any such term. Furthermore, R.H. Electronics may terminate our agreement at any time during the term upon 120 days prior notice. Flextronics (Israel) may terminate our agreement with them at any time during the term upon 180 days prior notice. We retain the right to procure independently any of the components used in our products. Both contractors have U.S. affiliates to which they can, with the prior consent of the Office of the Chief Scientist, transfer manufacturing of our products if necessary, in which event we may be required to pay increased royalties to the Office of the Chief Scientist. We expect that it would take approximately six months to transition manufacturing of our products to an alternate manufacturer.

We design and develop internally a number of the key components for our products, including printed circuit boards and software. Some of our product’s hardware components are obtained from single or limited sources. Since our products have been designed to incorporate these specific components, any change in these components due to an interruption in supply or our inability to obtain such components on a timely basis would require engineering changes to our products before we could incorporate substitute components. In particular, we purchase the central processing unit for our Service Gateway platforms and for our NetEnforcer AC-1400, AC-3000, AC-5000 and AC-10000 from NetLogic Microsystems, Inc. (through the acquisition of Raza Microelectronics, Inc.) and for our NetE nforcer AC-400 and our NetEnforcer AC-800 from Intel Corporation and we have agreed to purchase the network processor for our NetEnforcer AC-1000 and our NetEnforcer AC-2500 from Hifn Inc. We carry approximately three to six months of inventory of key components. We also work closely with our suppliers to monitor the end-of-life of the product cycle for integral components, and believe that in the event that they announce end of life, we will be able to increase our inventory to allow enough time for replacing such components. We do not have a supply agreement with Intel Corporation and the agreements with our other suppliers do not contain any minimum purchase or supply commitments. We have been informed by Hifn that it is their general policy to provide their customers with a six-month last-time-buy option and twelve months to take delivery of the product in the event that Hifn decides to discontinue production of the network processor. Product testing and quality assurance is performed by our contract man ufacturer using tests and automated testing equipment and according to controlled test documentation we specify. We also use inspection testing and statistical process controls to assure the quality and reliability of our products.

Competition

Our principal competitors are Cisco Systems (through the acquisitions of P-Cube and Starent Networks, Corp.) and Sandvine in the service provider market, and Blue Coat Systems, Inc. (through its acquisition of Packeteer) in the enterprise market. We also compete with a number of smaller competitors such as CloudShield Technologies, Inc. and Procera Networks, Inc., and we compete indirectly with router and switch infrastructure companies that offer features, which address some of the problems that our products address. We also face competition from companies that offer partial solutions addressing only one aspect of the challenges facing broadband providers, such as network monitoring or security. We compete on the basis of product performance, such as speed and number of applications identified, ease of use and installation, and customer support. Price is also an important, although not the principal, basis on which we compete. See “ITEM 3: Key Information—Risk Factors—We may be unable to compete effectively with other companies in our market who offer, or may in the future offer, competing technologies.”

Intellectual Property

Our intellectual property rights are very important to our business. We believe that the complexity of our products and the know-how incorporated in them makes it difficult to copy them or replicate their features. We rely on a combination of confidentiality and other protective clauses in our agreements, copyright and trademarks to protect our know-how. We also restrict access to our servers physically and through closed networks since our product designs and software are stored electronically and thus are highly portable.

We customarily require our employees, distributors, resellers, software testers and contractors to execute confidentiality agreements or agree to confidentiality undertakings when their relationship with us begins. Typically, our employment contracts also include the following clauses: assignment of intellectual property rights for all inventions developed by employees, non-disclosure of all confidential information, and non-compete clauses, which generally restrict the employee for six months following termination of employment. The enforceability of non-compete clauses in certain jurisdictions in which we operate may be limited. Because our product designs and software are stored electronically and thus are highly portable, we attempt to reduce the portability of our designs and software by physically protecting our servers through the use of closed networks, which prevent external access to our servers.

The communications equipment industry is characterized by constant product changes resulting from new technological developments, performance improvements and lower hardware costs. We believe that our future growth depends to a large extent on our ability to be an innovator in the development and application of hardware and software technology. As we develop the next generation products, we intend to pursue patent protection for our core technologies in the telecommunications segment. We plan to seek patent protection in our largest markets and our competitors’ markets, for example in the United States and Europe. As we continue to move into markets, such as Japan, Korea and China, we will evaluate how best to protect our technologies in those markets. We intend to vigorously prosecute and defend t he rights of our intellectual property.

As of December 31, 2009, we had two U.S. patents and two pending patent applications in the United States. We expect to formalize our evaluation process for determining which inventions to protect by patents or other means. We cannot be certain that patents will be issued as a result of the patent applications we have filed.

We have obtained U.S. trademark registrations for certain of our key marks that we use to identify our products or services, including “NetEnforcer” and “Allot Communications.”

We are a leading provider of intelligent IP service optimization solutions for DSL, wireless and mobile broadband carriers, cable operator service providers, and enterprise. Our portfolio of hardware platforms and software applications utilizes advanced DPI technology to transform broadband pipes into smart networks that can rapidly and efficiently manage data over mobile and wireline networks and deploy value added Internet services. End-customers use our solutions to create sophisticated policies to monitor network applications, enforce quality of service policies that guarantee mission-critical application performance, mitigate security risks and leverage network infrastructure investmen ts. Our carrier-class products are used by service providers to offer subscriber-based and application-based tiered services that enable them to optimize their service offerings, reduce churn rates and increase ARPU. We market and sell our products through a variety of channels, including direct sales and through our channel partners, which include distributors, resellers, OEMs and system integrators. End customers of our products include carriers, mobile operators, cable operators, wireless, wireline and satellite Internet service providers, educational institutions, governments and enterprises.

There has been a rapid proliferation of broadband networks in recent years, which has been largely driven by demand from users for faster and more reliable access to the Internet and by the proliferation in the number and complexity of broadband applications. The Internet, which was designed originally to support web surfing and e-mail applications, now supports numerous advanced services, such as interactive gaming and video conferencing. In addition, there has been an exponential increase in over-the-top Internet services, such VoIP and video streaming. These new applications are driving large service providers to explore ways to efficiently manage bandwidth resources in view of these and other bandwidth-heavy applications. As a result, a number of these service providers a re considering deploying DPI technology in their networks. We believe that large service providers, as well as cable and mobile operators, present a significant market opportunity and are an important element of our long term strategy.

In 2009, the primary driver of our growth was the mobile market, which was highlighted by our signing a frame agreement towards the end of the second quarter with a global Tier 1 mobile operator group. Revenues in 2009 from this customer accounted for 15% of our total revenues.

Revenues

We generate revenues from two sources: (1) sales of our network traffic management systems and our application suites, and (2) maintenance and support services, including installation and training. We generally provide maintenance and support services pursuant to a one- or three-year maintenance and support program, which may be purchased by customers at the time of product purchase or on a renewal basis.

We recognize revenues from product sales when persuasive evidence of an agreement exists, delivery of the product has occurred, no significant obligations with respect to implementation remain, the fee is fixed or determinable, and collection is probable. We grant a one-year hardware warranty and a three-month software warranty on all of our products and record a liability at the time the product’s revenue is recognized. We estimate the liability of possible warranty claims based on our historical experience. Warranty claims have to date been immaterial to our results of operations. Maintenance and support revenues are recognized on a straight line basis over the term of the applicable maintenance and support agreement.. See “—Critical Accounting Policies and Estimates—Revenue Rec ognition” below.

Customer concentration. In 2009, we derived 15% of our revenues from global Tier 1 mobile operator group. In 2008 and 2007, no single customer accounted for 10% or more of our revenues.

Cost of revenues and gross margins

Our product cost of revenues consists primarily of costs of materials, manufacturing services and overhead, warehousing, testing and royalties paid primarily to the Office of the Chief Scientist of the Israeli Ministry of Industry, Trade and Labor. Our services cost of revenues consist primarily of salaries and related personnel costs for our customer support staff as well as royalty payments mentioned above. We expect cost of revenues to increase as a result of the increase in our product and service revenues, the increased sales of our higher end products, primarily consisting of our Service Gateway platforms and the NetEnforcer AC-10000 and sale of extended service suites to large scale customers that will require additional personnel hiring and other expenditures. This increase may be offset by incre ased sales of our network management application suites as their direct cost of revenues are expected to be lower. As a result, our gross margins as a percentage of revenues may decrease.

Operating expenses

Research and development. Our research and development expenses consist primarily of salaries and related personnel costs, costs for subcontractor services, depreciation, rent and costs of materials consumed in connection with the design and development of our products. We expense all of our research and development costs as they are incurred. Our net research and development expenses are comprised of gross research and development expenses offset by financing through royalty-bearing grants from the Office of the Chief Scientist. Such participation grants are recognized at the time at which we are entitled to such grants on the basis of the costs incurred and included as a deduction of research and developme nt expenses (See “—Government Grants” below). We believe that significant investment in research and development is essential to our future success and expect that in future periods our research and development expenses will increase on an absolute basis.

Sales and marketing. Our sales and marketing expenses consist primarily of salaries and related personnel costs, travel expenses, costs associated with promotional activities such as public relations, conventions and exhibitions, rental expenses, depreciation and commissions paid to third parties. We intend to continue our activities to target the service provider market and therefore we expect that sales and marketing expenses will increase on an absolute basis in the future as we hire additional sales, marketing and presale support personnel, continue to promote our brand, establish marketing channels and expand our presence worldwide.

General and administrative. Our general and administrative expenses consist of salaries and related personnel costs, rental expenses, costs for professional services and depreciation. We expect these expenses to increase on an absolute basis as we hire additional personnel and incur additional costs related to the growth of our business as we increase our global presence. General and administrative expenses also include costs associated with corporate governance, tax compliance, compliance with the rules implemented by the U.S. Securities and Exchange Commission and NASDAQ, premiums for our director and officer liability insurance and for defending the class action lawsuit filed against us and certain of our directors and officers. See “ITEM 8: Financial Information—Consolidated Statements and Other Financial Information—Legal Proceedings.”

Financial expenses, net

Financial expenses, net consists primarily of interest earned on our cash balances and other financial investments, foreign currency exchange gains or losses, devaluation of marketable securities and bank fees.

As of December 31, 2009, we held $27.9 million of principal invested in ARS, which were rated AAA and AA at the time of purchase. Due to the continued deterioration of, and uncertainties in, the credit and capital markets, our ARS have experienced multiple failed auctions due to a lack of liquidity in the market. A number of our ARS have had their credit rating downgraded. To date, our ARS have paid all their interest payments. Based on an analysis of their fair value, we have recorded in 2009 an impairment charge, of $3.0 million to financial and other expenses, net, in our statement of operations with respect to devaluation, which is considered “other than temporary.” If the credit and capital markets further deteriorate or we experience any additional ratings downgrades on any ongoing investments in our portfolio, including of ARS, we m ay incur additional impairments to our investment portfolio and record further impairment charges to our financial and other expenses, net, in our statement of operations. See “—Critical Accounting Policies and Estimates— Marketable Securities” below.

In addition, the financial and other income (expenses), net, may fluctuate due to foreign currency exchange gains or losses, as well as the interest rate changes. See “ITEM 11: Quantitative and Qualitative Disclosures About Market Risk – Foreign Currency Exchange Risk” and – Risk of Interest Rate Fluctuation.”

Approved and Privileged Enterprise

Our facilities in Hod-Hasharon, Israel have been granted Approved Enterprise status under the Investments Law and enjoy certain tax benefits. We expect to utilize these tax benefits after we utilize our net operating loss carry forwards. As of December 31, 2009, our net operating loss carry forwards for Israeli tax purposes amounted to approximately $46 million. Income derived from other sources, other than the “Approved Enterprise,” during the benefit period will be subject to tax at the regular corporate tax rate. For more information about the tax benefits available to us as an Approved and Privileged Enterprise see “ITEM 10: Additional Information—Taxation and Government Programs—Law for the Encouragement of Capital Investments, 1959.”

Government Grants

Our research and development efforts have been financed, in part, through grants from the Office of the Chief Scientist under our approved plans in accordance with the Israeli Law for Encouragement of Research and Development in the Industry, 1984, or the Research and Development Law. Through December 31, 2009, we had received approval and recorded in our books grants totaling $19.2 million from the Office of the Chief Scientist, excluding $4.1 million attributed to NetReality products. Under Israeli law and the approved plans, royalties on the revenues derived from sales of all of our products are payable to the Israeli government, generally at the rate of 3.0% during the first three years and 3.5% beginning with the fourth year, up to the amount of the received grants as adjusted for fluctuation in the U.S. dollar/shekel exchange rate. The amounts received after January 1, 1999 bear interest at twelve month LIBOR as at the beginning of the year in which a grant is approved. Our obligation to pay these royalties is contingent upon actual consolidated sales of our products and no payment is required if no sales are made. As of December 31, 2009, we had an outstanding contingent obligation to pay royalties in the amount of $10.4 million.

The government of Israel does not own proprietary rights in knowledge developed using its funding and there is no restriction related to such funding on the export of products manufactured using the know-how. The know-how is, however, subject to other legal restrictions, including the obligation to manufacture the product based on the know-how in Israel and to obtain the Office of the Chief Scientist’s consent to transfer the know-how to a third party, whether in or outside Israel. These restrictions may impair our ability to outsource manufacturing or enter into similar arrangements for those products or technologies and they continue to apply even after we have paid the full amount of royalties payable for the grants.

If the Office of the Chief Scientist consents to the manufacture of the products outside Israel, the regulations allow the Office of the Chief Scientist to require the payment of increased royalties, ranging from 120% to 300% of the amount of the grant plus interest, depending on the percentage of foreign manufacture. If the manufacturing is performed outside of Israel by us, the rate of royalties payable by us on revenues from the sale of products manufactured outside of Israel will increase by 1% over the regular rates. If the manufacturing, marketing and distribution is carried outside of Israel, the rate of royalties payable by us on those revenues will be calculated in accordance with the proportion between the grant received and the grant plus the amount of our own investments in research and devel opment for such technology. The Research and Development Law further permits the Office of the Chief Scientist, among other things, to approve the transfer of manufacturing or manufacturing rights outside Israel in exchange for an import of certain manufacturing or manufacturing rights into Israel as a substitute, in lieu of the increased royalties.

The Research and Development Law provides that the consent of the Office of the Chief Scientist for the transfer outside of Israel of know-how derived out of an approved plan may only be granted under special circumstances and subject to fulfillment of certain conditions specified in the Research and Development Law as follows: (a) the grant recipient pays to the Office of the Chief Scientist an amount based on the scope of the support received, the royalties that were paid by the company, the amount of time that elapsed since the date on which the grants were received, and the sale price (according to certain formulas), except if the grantee receives from the transferee of the know-how an exclusive, irrevocable, perpetual unlimited license to fully utilize the know-how and all related rights; (b) the gr ant recipient receives know-how from a third party in exchange for its Office of the Chief Scientist funded know-how; or (c) such transfer of Office of the Chief Scientist funded know-how arises in connection with certain types of cooperation in research and development activities.

In September 2002, we acquired the assets of NetReality, an Israeli manufacturer, from a receiver pursuant to a court ruling. In connection with the NetReality acquisition, we assumed a commitment to pay royalties to the Office of the Chief Scientist up to the amount of the contingent liabilities derived from the grants that had been received by NetReality prior to the acquisition. Following the acquisition of NetReality, the Office of the Chief Scientist merged the NetReality approved plans with our other approved plans under a unified file. In April 2007, the Office of the Chief Scientist notified us of its decision, per our request, to separate the NetReality related approved plans from other approved plans. The Office of the Chief Scientist also approved the discontinuation of the NetReality related approved plans and as a result we were released from the obligation to pay the balance of the royalties in the amount of $4.7 million.

Factors Affecting Our Performance

Our business, financial position and results of operations, as well as the period-to-period comparability of our financial results, are significantly affected by a number of factors, some of which are beyond our control, including:

Size of end-customers and sales cycles. We have a global, diversified end-customer base consisting primarily of service providers and enterprises. We are making efforts to increase our sales to large service providers. The deployment of our products by small and midsize enterprises and service providers can be completed relatively quickly with a limited number of NetEnforcer and/or Service Gateway systems compared to the number required by large service providers. Large service providers take longer to plan the integration of our solutions into their existing networks and to set goals for the implementation of the technology. Sales to large service providers are therefore more complicated as they involve a r elatively larger number of network elements and solutions, as well as NetEnforcer and/or Service Gateway systems. We are seeking to achieve further significant customer wins in the large service provider market that would positively impact our future performance. However, our performance is also influenced by sales cycles for our products, which typically fluctuate based upon the size and needs of end-customers that purchase our products. We expect that increased sales to large service providers of Service Gateway platforms will result in longer sales cycles that will increase unpredictability regarding the timing of our sales and may cause our quarterly and annual operating results to fluctuate if a significant customer delays its purchasing decision and/or defers an order. Furthermore, longer sales cycles may result in delays from the time we increase our operating expenses and make investments in inventory, until the time that we generate revenue from related product sales.

Average selling prices. Our performance is affected by the selling price of our products. We price our products based on several factors, including manufacturing costs, the stage of the product’s life cycle, competition, technical complexity of the product, discounts given to channel partners in certain territories, customization and other special considerations in connection with larger projects. We typically are able to charge the highest price for a product when it is first introduced to the market. We expect that the average selling prices for our products will decrease over the product’s life cycle as our competitors introduce new products and DPI technology becomes more standardized. In ord er to maintain or increase our current price, we expect that we will need to enhance the functionality of our existing products by offering higher system speeds, additional value added services and features, such as additional security functions, supporting additional applications and enhanced reporting tools. We also from time to time introduce enhanced products, typically higher end models that include new architecture and design and new capabilities, primarily to higher end models. Such enhanced products typically increase our average selling price. To further offset such declines, we sell maintenance and support programs on our products, and as our customer base and number of field installations grow our related service revenues are expected to increase.

Cost of revenues and cost reductions. Our cost of revenues as a percentage of total revenues was 24.7% for 2007, 26.1% for 2008 and 28.3% for 2009. Our products use off-the-shelf components and typically the prices of such components decline over time. However, the introduction and sale of new or enhanced products and services may result in an increase in our costs of revenues. We make a continuous effort to identify cheaper components of comparable performance and quality. We also seek improvements in engineering and manufacturing efficiency that will reduce costs. Since our cost of revenues also include royalties paid to the Office of the Chief Scientist, our cost of sales may be impacted positively or neg atively by actions of the Israeli government changing the royalty rate. Our products incorporate features that require payment of royalties to third parties. In addition, new products, such as the Service Gateway series, usually have higher costs during the initial introduction period. We generally expect such costs to decline as the product matures and sales volume increases. Introduction of new products may also involve a significant decrease in demand for older products. Such a decrease may result in a devaluation or write-off of such older products and their respective components. In 2009, we recorded a write-off of $0.8 million of inventory to our cost of revenues for products and components, out of which $0.3 million is attributable to components that became obsolete due to the introduction of new products. The growth of our customer base is usually coupled with increased service revenues primarily resulting from increased maintenance and support. In addition, the growth in our installed base with larg e service providers may result in increased demand for professional services such as training and installation services. Increase in demand for such services may require us to hire additional personnel and incur other expenditures. However, these additional expenses, handled efficiently, may be utilized to further support the growth of our customer base and increase service revenues.

Currency exposure. A majority of our revenues and a substantial portion of our expenses are denominated in the U.S. dollar. However, a significant portion of the expenses associated with our global operations, including personnel and facilities related expenses, are incurred in currencies other than the U.S. dollar. This is the case primarily in Israel and to a lesser extent in other countries in Europe and Asia. Consequently, a decrease in the value of the U.S. dollar relative to local currencies will increase the dollar cost of our operations in these countries. A relative decrease in the value of the U.S. dollar would be partially offset to the extent that we generate revenues in such currencies. In order to partially mitigate this exposure we made in the past an d may decide from time to time to enter into hedging transactions. We may discontinue hedging activities at any time. As such decisions involve substantial judgment and assessments primarily regarding future trends in foreign exchange markets which are very volatile as well as our future level and timing of cash flows of these currencies, we cannot provide any assurance that such hedging transactions will not affect our results of operations when they are materialized. See Note 14 to our consolidated financial statements for further information.

Interest rates exposure. We have a significant amount of cash that is currently invested primarily in interest bearing vehicles, such as bank time deposits, money market funds, U.S. government treasury bills and ARS. These investments expose us to the risk of changes in interest rates.

Critical Accounting Policies and Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. These estimates and judgments are subject to an inherent degree of uncertainty and actual results may differ. Our significant accounting policies are more fully described in Note 2 to our consolidated financial statements included elsewhere in this annual report. Certain of our accounting policies are particularly important to the portrayal of our financial position and results of operations. In applyin g these critical accounting policies, our management uses its judgment to determine the appropriate assumptions to be used in making certain estimates. Those estimates are based on our historical experience, the terms of existing contracts, our observance of trends in our industry, information provided by our customers and information available from other outside sources, as appropriate. With respect to our policies on revenue recognition and warranty costs, our historical experience is based principally on our operations since we commenced selling our products in 1998. Our estimates are primarily guided by observing the following critical accounting policies:

●

Revenue Recognition

●

Allowance for Doubtful Accounts

●

Stock Based Compensation

●

Inventories

●

Marketable Securities

●

Impairment of Goodwill and other Long Lived Assets

●

Contingencies

Since each of the accounting policies listed above, require exercise of certain judgment and use of estimates, actual results may differ from our estimations and as a result would increase or decrease our future revenues and net income.

Revenue recognition. We generate revenues primarily from the sale of hardware and software products and from the provision of maintenance and support services. We sell our products primarily through resellers, distributors, OEMs, system integrators and value added resellers, all of whom are considered end-customers from our perspective. We recognize revenues from sales of our products in accordance with the Accounting Standards Codification No. 985-605 (formerly, Statement of Position SOP 97-2). 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 recogniz ed when the following four criteria are met: (i) persuasive evidence of an arrangement exists; (ii) delivery has occurred; (iii) the fee is fixed and determinable; and (iv) collection is probable.

Many of our product sales include multiple elements. Such elements typically include several or all of the following: hardware, software licenses, hardware and software maintenance, technical support and training 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, we use the residual method to allocate value to each element when sufficient specific objective evidence exists for all undelivered elements, but does not exist for the delivered element, typically the hardware appliance and software license. Under the residual method, each undelivered element is allocated with a value based on vendor specific objective evidence of fair value for that element and the remainder of the total arran gement fee is allocated to the delivered element(s).

Maintenance and support revenue, including any portion deferred from multiple element arrangements based on the principles mentioned above are recognized on a straight-line basis over the term of the applicable maintenance and support agreement.

We provide a provision for sales incentives, product returns and stock rotation based on the specific arrangements, if any, and our experience with historical sales returns, stock rotations and other known factors, in accordance with Accounting Standards Codification No. 605, “Revenues Recognition When Right of Return Exists”, formerly known as Statement of Financial Accounting Standard No. 48 (“ASC No. 605”) at the time the related revenue is recognized.

We grant a one-year hardware warranty and three-month software warranty on all of our products. We estimate the costs that may be incurred under our warranty arrangements and record a liability in the amount of such costs at the time product revenue is recognized. We periodically assess the adequacy of the recorded warranty liabilities and adjust the amounts as necessary.

Allowance for Doubtful Accounts. We evaluate the collectability of our accounts receivable on a specific basis. We estimate this allowance based on our judgment as to our ability to collect outstanding receivables. We primarily base this judgment on an analysis of significant outstanding invoices, the age of the receivables, our historical collection experience and current economic trends. In circumstances where we are aware of a specific customer’s inability to meet its financial obligations to us, we record a specific allowance against amounts due to reduce the net recognized receivable to the amount we reasonably believe will be collected.

Accounting for Stock-Based Compensation. We account for stock based compensation in accordance with ASC No. 718. ASC No. 718 requires companies to estimate the fair value of equity-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 Statement of Operations. We recognize compensation expenses for the value of its awards granted based on the straight-line method over the requisite service period of each of the awards, net of estimated forfeitures. ASC No. 718 requires forfeitures to be estimated at the time of the grant and revise d, if necessary, in subsequent periods if actual forfeitures differ from those estimates. We applies ASC No. 718 and Accounting Standards Codification No. 505-50 (formerly, EITF No. 96-18), “Equity-Based Payments to Non-Employees” (“ASC No. 505-50”) with respect to options and warrants issued to non-employees. Accordingly, option valuation models to measure the fair value of the options and warrants at the measurement date as defined in ASC No. 505-50.

We recognize compensation expenses for the value of awards granted based on the straight-line method over the requisite service period of each of the awards, net of estimated forfeitures. ASC No. 718 requires forfeitures to be estimated at the time of the grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates.

On May 18, 2009, we granted 343,297 new options in exchange for 381,440 of our employees' stock options, previously granted on ten occasions during the years 2006-2008. We accounted for the exchange of options under the provisions of ASC No. 718 as a modification. As a result of the modification, our incremental compensation cost of $0.1 million will be recognized over the new service period beginning on the modification date. The unrecognized compensation cost remaining from the original grant date valuation in the amount of $0.6 million shall be recognized over the remainder of the original requisite period. For the year ended on December 31, 2009, we recorded an additional expense of $16,000 in our consolidated statements of operations with respect of this modification.

In connection with the grant of options, we recorded total stock-based compensation expense of $1.4 million in 2007, $1.7 million in 2008 and $2.3 million in 2009. In 2009, $0.1 million, $0.3 million, $0.8 million and $1.0 of our stock-based compensation expense resulted from cost of revenue, research and development expenses, sales and marketing expenses and general and administrative expenses, respectively, based on the department in which the recipient of the option grant was employed. As of December 31, 2009, we had an aggregate of $3.0 million of deferred unrecognized stock-based compensation remaining to be recognized. We estimate that this deferred unrecognized stock-based compensation balance will be amortized as follows: $1.7 million in 2010, $0.8 million in 2011 and $0.5 million in 2012 and the reafter

Inventories. We value our inventories at the lower of cost or estimated market value. Cost being determined on the basis of First In, First Out (“FIFO”) cost method for raw materials and out-of-pocket manufacturing costs. Indirect costs are allocated on average basis. We estimate market value based on our current pricing, market conditions and specific customer information. We write off inventory for slow-moving items or technological obsolescence. We also assess our inventories for obsolescence based upon assumptions about future demand and market conditions. Actual future results may differ from our assessments and result in further devaluations or write-downs that will affect our future result s of operations. Once inventory is written off, a new cost basis for these assets is established for future periods. Inventory write offs totaled $0.2 million in 2007, $0.2 million in 2008 and $0.8 million in 2009. The write-offs we incurred in 2009 consist of a $0.5 million write-off of old products that based on our estimation have become obsolete due to introduction of newer products.

Marketable securities. We account for our investments in marketable securities using Accounting Standards Codification No. 320 (formerly, Statement of Financial Accounting Standard No. 115), “Investments – Debt and Equity Securities” (“ASC No. 320”).

We determine the appropriate classification of marketable securities at the time of purchase and evaluate such designation as of each balance sheet date. We classify all of our marketable securities as available for sale. Available for sale securities are carried at fair value, with the unrealized gains and losses, reported in “accumulated other comprehensive income (loss)” in shareholders’ equity. Realized gains and losses on sale of investments are included in earnings and are derived using the specific identification method for determining the cost of securities. The amortized cost of debt securities is adjusted for amortization of premiums and accretion of discounts to maturity. Such amortization together with interest and dividends on securities are included in financial income, ne t, if any.

Until 2009, we recognized an impairment charge when a decline in the fair value of our investments below the cost basis is judged to be other-than-temporary. The entire difference between amortized cost and fair value is recognized in earnings. Factors considered in making such a determination include the duration and severity of the impairment, the reason for the decline in value and the potential recovery period.

In April 2009, we adopted the FASB’s updated guidance relating to investments and debt securities, which amends the other-than-temporary impairment ("OTTI") guidance in U.S. GAAP. Under the updated guidance, if other-than-temporary impairment occurs, and it is more likely than not that we will not sell the investment or debt security before the recovery of its amortized cost basis, then the other-than-temporary impairment is separated into (a) the amount representing the credit loss and (b) the amount related to all other factors. The amount of the total other-than-temporary impairment related to credit loss is recognized in earnings. The amount of the total other-than-temporary impairment related to other factors is recognized in accumulated other comprehensive income. As a result of the adoption of this update accounting guidance, we recorde d a cumulative effect adjustment of $7,7 million to reclassify the non-credit component of previously recognized impairments from accumulated deficit to accumulated other comprehensive income (loss). See Note 4 to our consolidated financial statements for further information .

As of December 31, 2009, we held marketable securities in U.S. dollars in the United States. Securities consisting of ARS were classified as long term investments. We hold ARS with par value of $27.9 million that bear interest linked to LIBOR. We determined the fair value of the ARS as of December 31, 2009, at $14.5 million, based on a third party valuation using a discounted cash flow model for each security, whose inputs and assumptions include the market conditions related to such security as well as the underlying structure of the security, the financial standing of the issuer, stated maturities, estimates of the probability of the issue being called at par prior to final maturity, estimates of the probability of defaults and recoveries, auctions failure and successful auction or repurchase at par for each period, expected changes in interest rate s paid on the securities, interest rates paid on similar instruments. During 2009, we recorded an impairment charge of $3.0 million in our statement of operations as a result of a further devaluation related to credit losses. In addition, during 2009 we recorded an unrealized gain of $2.2 million to other comprehensive income in our balance sheet for appreciation of certain ARS in our portfolio. See “ITEM 3: Key Information—Risk Factors—We have invested a substantial portion of our cash in auction-rate securities, which subjects us to liquidity and investment risk. Due to uncertainties in the capital markets regarding auction-rate securities, we recorded impairment charges in 2007, 2008 and 2009, and, if the fair value of these investments were to decline further, we could be required to record further impairment charges related to these investments.” If the fair value of these ARS was to decline further, we could be required to record further impairment charges related to these ARS i n the future.

Impairment of Goodwill and Long Lived Assets. Goodwill represent the excess of the purchase price over the fair value of net assets of purchased businesses is recorded as goodwill. Under Accounting Statement Codification No. 350, formerly known as Statement of Accounting Standards No. 142, “Goodwill and Other Intangible Assets” (“ASC No. 350”) goodwill and intangible assets deemed to have indefinite lives are tested for impairment annually, or more often if there are indicators to impairment present.

We perform our annual impairment analysis of goodwill as of December 31 of each year, or more often as applicable. The provisions of ASC No. 350 require that a two-step impairment test be performed on goodwill at the level of the reporting units. In the first step, or Step 1, we compare the fair value of each reporting unit to its carrying value. If the fair value exceeds the carrying value of the net assets, goodwill is considered not impaired, and we are not required to perform further testing. If the carrying value of the net assets exceeds the fair value, then we must perform the second step, or Step 2, of the impairment test in order to determine the implied fair value of goodwill. If the carrying value of goodwill exceeds its implied fair value, then we would record an impairment loss equal to the difference. If and when we are required to perfo rm a Step 2 analysis, determining the fair value of its net assets and its off-balance sheet intangibles would require it to make judgments that involve the use of significant estimates and assumptions.

We believe that our business activity and management structure meet the criterion of being a single reporting unit for accounting purposes.

Our long lived assets consist primarily of property and equipment and other intangible assets. Our long lived assets are amortized using the straight-line basis over their estimated useful lives. The carrying amount of these assets to be held and used is reviewed whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable. Recoverability of these assets is measured by comparison of the carrying amount of the asset to the future undiscounted cash flows the asset is expected to generate. If the asset is considered to be impaired, the amount of any impairment is measured as the difference between the carrying value and the fair value of the impaired asset. As this test requires considerable judgment and estimation of future cash flows, changes in these estimations may affect our results of operations si gnificantly. Based on the impairment test performed as of December 31, 2009, no impairment was identified.

Contingencies. From time to time, we are defendant or plaintiff in various legal actions, which arise in the normal course of business. 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 for these contingencies, if any, which would impact our results of operations, is made after considered analysis of each individual action together with our legal advisors. The required reserves may change in the future due to new developments in each matter or changes in circumstances and estimations. A change in the required reserves would impact our results of operations in the period the change is made.

Recent Accounting Pronouncements

In April, 2009, we adopted the FASB’s updated guidance Accounting Standards Codification No. 820-10 (formerly, FSP No.157-04), related to fair value measurements and disclosures, which provides additional guidance for estimating fair value in accordance with the guidance related to fair value measurements when the volume and level of activity for an asset or liability have significantly decreased. The updated standard also includes guidance on identifying circumstances that indicate a transaction is not orderly. We adopted this standard effective April 1, 2009. The adoption of this guidance did not have a material effect on the consolidated financial statements.

In May 2009, the FASB issued Accounting Standards Codification No. 855 (formerly, FASB Statement No.165), “Subsequent Events” ("ASC No. 855"). This standard is intended to establish general standards of accounting for and disclosures of events that occur after the balance sheet date but before financial statements are issued or are available to be issued. Specifically, this standard sets forth the period after the balance sheet date during which management of a reporting entity should evaluate events or transactions that may occur for potential recognition or disclosure in the financial statements, the circumstances under which an entity should recognize events or transactions occurring after the balance sheet date in its financial statements, and the disclosures that an entity should make about events or transactions that occur red after the balance sheet date. ASC No. 855 is effective for fiscal years and interim periods ended after June 15, 2009. We adopted this standard effective June 15, 2009. The adoption of this guidance did not have a material effect on our consolidated financial statements.

In June 2009, the FASB issued a standard that established the FASB Accounting Standards Codification (“ASC”) and amended the hierarchy of generally accepted accounting principles (“GAAP”) such that the ASC became the single source of authoritative U.S. GAAP. Rules and interpretive releases issued by the SEC under authority of federal securities law are also sources of the authoritative GAAP for SEC registrants. All other literature is considered non-authoritative. New accounting standards issued subsequent to June 30, 2009 are communicated by the FASB through Accounting Standards Updates (“ASUs”). The ASC is effective for the Company from September 1, 2009. Throughout the notes to the consolidated financial statements references that were previously made to former authoritative U.S. GAAP pronouncements have been cha nged to coincide with the appropriate section of the ASC.

In October 2009, the FASB issued an update to ASC No. 985-605, “Software-Revenue Recognition” (originally issued as EITF 09-3). In accordance with the update to the ASC, tangible products containing software components and non-software components that function together to deliver the tangible product's essential functionality are excluded from the scope of the software revenue recognition guidance. In addition, hardware components of a tangible product containing software component are always excluded from the software revenue guidance. The mandatory adoption is on January 1, 2011, with earlier adoption permitted. We may elect to adopt the update prospectively, to new or materially modified arrangements beginning on the adoption date, or retrospectively, for all periods presented. We currently evaluating the impact on its consolidated resu lts of operations and financial condition, and has not yet determined the adoption date.

In October 2009, the FASB issued an update to ASC No. 605-25, “Revenue recognition – Multiple-Element Arrangements,” that provides amendments to the criteria for separating consideration in multiple-deliverable arrangements to:

●

provide updated guidance on whether multiple deliverables exist, how the deliverables in an arrangement should be separated, and how the consideration should be allocated;

●

require an entity to allocate revenue in an arrangement using estimated selling prices (“ESP”) of deliverables if a vendor does not have vendor-specific objective evidence of selling price (“VSOE”) or third-party evidence of selling price (“TPE”); and

●

eliminate the use of the residual method and require an entity to allocate revenue using the relative selling price method.

●

require expanded disclosures of qualitative and quantitative information regarding application of the multiple-deliverable revenue arrangement guidance.

We may elect to adopt the update prospectively, to new or materially modified arrangements beginning on the adoption date, or retrospectively, for all periods presented. We currently evaluating the impact on its consolidated results of operations and financial condition, and has not yet determined the adoption date

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

Revenues

Products. Product revenues increased by $2.5 million, or 9%, to $29.6 million in 2009 from $27.1 million in 2008. The increase is primarily attributable to increased sales of our high-end products, primarily the Service Gateway platforms, driven by the agreement we signed with a global Tier 1 mobile operator group. This increase was partially offset by a decrease in sales of our low-end products.

Services. Service revenues increased by $2.1 million, or 21.3%, to $12.1 million in 2009 from $10 million in 2008. The increase in service revenues is primarily attributable to an increase in our installed base.

Product revenues, which comprised 71% of our total revenues in 2009, decreased by 2.1% compared to 2008, while service revenues increased by a similar percentage.

During 2009, revenues in Europe increased by $6.5 million or 53.3% compared to 2008, which was primarily attributable to an agreement signed with a global Tier 1 mobile operator group. Revenues in the Americas decreased by $1.9 million or 17% compared to 2008. Revenues in Asia and Oceania decreased by $0.2 million or 2% compared to 2008. Revenues in the Middle East and Africa increased by $0.2 million or 9% compared to 2008.

Cost of revenues and gross margin

Products. Cost of product revenues increased by $1.9 million, or 23%, to $10 million in 2009 from $8.2 million in 2008. This increase is consistent with the increase in product revenues. Product gross margin decreased to 65.9% in 2009 from 69.7% in 2008. This decrease is primarily attributable to higher sales volume of our high-end products, which require higher material and labor costs as well as an increased inventory write-off, of which $0.5 million is attributable to the introduction of new products in 2009.

Services. Service cost of revenues increased by $0.2 million, or 16.2 %, to $1.7 million in 2009 from $1.5 million in 2008. This increase is primarily attributable to higher support personnel expenses. Services gross margin increased to 85.6 % in 2009 from 85.0% in 2008.

Total gross margin decreased to 71.6% in 2009 from 73.9% in 2008. This decrease is primarily attributable to the decrease in product gross margin as described above.

Operating expenses

Research and development. Gross research and development expenses decreased by $2.9 million, or 19.8%, to $11.7 million in 2009 from $14.6 million in 2008. This decrease is primarily attributable to a decrease in salaries and labor costs of approximately $2.7 million, which principally resulted from efficiency measures taken by management, consisting primarily of a salary reduction and certain reductions in force at the beginning of the year, as well as appreciation of the U.S. dollar relative to the shekel and decrease of $0.2 million in maintenance car, which resulted from reduction in car leasing.

Research and development expenses, net of received and accrued grants from the Office of the Chief Scientist, decreased by approximately $2.7 million, or 22.5%, to $9.3 million in 2009 from $12.0 million in 2008. Grants received from the Office of the Chief Scientist totaled $2.4 million in 2009 compared to $2.7 million in 2008. The decrease in grants received is primarily attributable to the appreciation of U.S. dollar relative to the shekel. Research and development expenses, net, as a percentage of revenues decreased to 22.2% in 2009 from 32.2% in 2008.

Sales and marketing. Sales and marketing expenses increased by $0.6 million, or 3.2%, to $20.4 million in 2009 from $19.8 million in 2008. This increase is primarily attributable to increased commissions of approximately $0.5 million, increased stock based compensation expenses of approximately $0.3 million, increased travel expenses of approximately $0.5 million, both resulting from increased sales, increased depreciation primarily attributable to write-off of old demonstration units of approximately $0.4 million due to the introduction of new products, partially offset by $1.1 million attributable to decrease in salaries and related expenses, primarily related to salary reduction, appreciation of the U.S. dollar relative to the shekel and a decrease in the average level of employees compared to 2008.

Sales and marketing expenses, as a percentage of revenues decreased to 48.9% in 2009 from 53.3% in 2008.

General and administrative. General and administrative expenses decreased by $0.7 million, or 10.3%, to $5.5 million in 2009 from $6.2 million in 2008. This decrease is primarily attributable to a decrease of approximately $0.4 million in salaries and related expenses primarily due to salary reduction and appreciation of the U.S. dollar relative to the shekel, decrease of $0.1 million in insurance expenses and a decrease of variable overhead and personnel expenses of approximately $0.4 million, partially offset by an increase of $0.2 million stock-based compensation expenses.

General and administrative expenses as a percentage of revenues decreased to 13.2% in 2009 from 16.6% in 2008.

Financial and other income (expenses), net. Financial and other expenses, net decreased by $3.2 million to $2.3 million in 2009 from $5.5 million in 2008. The decrease in financial and other expenses, net is primarily attributable to a decrease in net impairment charge of $4.7 related to our investment in ARS and a decrease of $0.2 million in foreign currency transactions and other related financial expenses, partially offset by a decrease in interest received on cash balances and marketable securities of $1.7 million, primarily attributable to the decline in interest rates in 2009.

Income tax expense. Income tax expense was $0.1 million in 2009 compared to an income tax expense of $0.2 million in 2008. The decrease is primarily attributable to a decrease in our tax provisions in the United States.

Year Ended December 31, 2008 Compared to Year Ended December 31, 2007

Revenues

Products. Product revenues increased by $2.0 million, or 8%, to $27.1 million in 2008 from $25.1 million in 2007. The increase is primarily attributable to successful deployment of our first product of the Service Gateway series.

Services. Service revenues increased by $2.6 million, or 35.1%, to $10 million in 2008 from $7.4 million in 2007. The increase in service revenues is primarily attributable to an increase in our installed base.

Revenues from products, which comprised 73.1% of our total revenues in 2008, decreased by 4% compared to 2007, while the service revenues increased by a similar percentage.

Cost of revenues and gross margin

Products. Cost of product revenues increased by $1.6 million, or 24.2%, to $8.2 million in 2008 from $6.6 million in 2007. This increase is consistent with the increase in revenues. Product gross margin was 69.7% in 2008 compared to 73.7% in 2007. This decrease is primarily attributable to higher sales volume of our high-end products, which require higher material and labor costs.

Services. Service cost of revenues increased by $0.1 million, or 7.1%, to $1.5 million in 2008 from $1.4 million in 2007. This increase is primarily attributable to increased royalties. Services gross margin was 85.0% in 2008 compared to 81.0% in 2007.

Total gross margin was 73.9% in 2008 compared to 75.3% in 2007.

Operating expenses

Research and development. Gross research and development expenses increased by $2.8 million, or 23.7%, to $14.6 million in 2008 from $11.8 million in 2007. This increase is primarily attributable to an increase in salaries and labor costs of approximately $1.3 million, which principally resulted from salary raises and the devaluation of the U.S. dollar relative to the shekel as well as the acquisition of the business of Esphion; an increase in other expenses, principally consisting of employee related expenses and overhead, of approximately $1.2 million; and an increase in depreciation of $0.3 million.

Research and development expenses, net of received and accrued grants from the Office of the Chief Scientist, increased by approximately $2.7 million, or 28%, to $12.0 million in 2008 from $9.3 million in 2007. Grants totaled $2.7 million in 2008 compared to $2.4 million in 2007. The increase in grants received is primarily attributable to the devaluation of U.S. dollar relative to the shekel. Research and development expenses, net, as a percentage of revenues increased to 32.2% in 2008 from 28.9% in 2007.

Sales and marketing. Sales and marketing expenses increased by $1.7 million in 2008, or 9.4%, to $19.8 million in 2008 from $18.1 million in 2007. This increase resulted from an increase in salaries and related expenses of $0.8 million, primarily related to an increase in presale support personnel, increased commissions resulting from increased sales, an increase of $0.6 million in travel expenses primarily due to increased sales and an increase of $0.3 million in depreciation.

Sales and marketing expenses, as a percentage of revenues decreased to 53.3% in 2008 from 55.6% in 2007.

General and administrative. General and administrative expenses increased by $0.6 million, or 10.7%, to $6.2 million in 2008 from $5.6 million in 2007. This increase is primarily attributable to an increase of $0.3 million in salaries and related expenses primarily due to devaluation of the U.S. dollar relative to the shekel, an increase in employee relate expenses and overhead expenses of $0.4 million and an increase in bad debt expenses of $0.1 million partially offset by a decrease in professional service and travel expenses of $0.2 million.

General and administrative expenses as a percentage of revenues decreased to 16.6% in 2008 from 17.2% in 2007.

Financial and other income (expenses), net. Financial and other income, net was $5.5 million in 2008 compared to $0.9 million in 2007. The increase in financial and other income, net is primarily attributable to a net impairment charge of $7.7 million compared to a net impairment charge of $4.9 million in 2007 related to our investment in ARS, a decrease in interest received on cash balances and marketable securities of $1.6 million, which is primarily attributable to the decline in interest rates in 2008, and an increase in interest and other expenses partially offset by a decrease in foreign currency transactions differences, net of $0.2 million.

Income tax expense. Income tax expense was $0.2 million in 2008 compared to an income tax expense of $0.5 million in 2007. The decrease is primarily attributable to a write-down of a withholding tax asset in 2007.

B. Liquidity and Capital Resources

From inception until consummation of our initial public offering we financed our operations primarily through private placements of our equity securities and, to a lesser extent, through borrowings from financial institutions. Sales of our equity securities including the consummation of our initial public offering resulted in net proceeds to us of approximately $112.7 million, net of issuance expenses.

As of December 31, 2009, we had $36.4 million in cash and cash equivalents, $2.3 million in restricted deposits and short term bank deposits and $14.5 million in marketable securities representing investments in ARS. As of December 31, 2009, our working capital, which we calculate by subtracting our current liabilities from our current assets, was $38.1 million.

Based on our current business plan, we believe that our existing cash balances, will be sufficient to meet our anticipated cash needs for working capital and capital expenditures for at least the next twelve months. In addition, we believe that the current lack of liquidity of the ARS will not have a material impact on our liquidity, cash flow or our ability to fund our operations for at least the next twelve months. If our estimates of revenues, expenses or capital or liquidity requirements change or are inaccurate and are insufficient to satisfy our liquidity requirements, we may seek to sell additional equity or arrange additional debt financing. In addition, we may seek to sell additional equity or arrange debt financing to give us financial flexibility to pursue attractive acquisition or investment opportunities that may arise in the future, alth ough we currently do not have any specific acquisitions or investments planned.

Operating activities. Net cash used in operating activities in 2009 was $0.4 million. Net cash used in operating activities consisted of our net loss of $7.7 million, an increase of $0.7 million in inventories, an increase of $1.7 million in trade receivables, a $0.2 million increase in accrued severance pay net, an increase of $1.6 million in other receivables and a capital gain adjustment to our net loss of $0.1 million partially offset by non-cash expenses primarily attributable to a $3.0 million impairment charge against ARS, depreciation and amortization of fixed and intangible assets, including fixed assets write-off of $3.0 mil lion and $2.3 million of stock-based compensation expense, and changes in balance sheet items that included a decrease of $0.3 million in long term deferred taxes, an increase of $0.7 million in deferred revenues and an increase of $2.3 million in trade and other payables.

Net cash used in operating activities in 2008 was $0.2 million. Net cash used in operating activities was primarily attributable to our net loss of $16.5 million and was partially offset by non-cash expenses consisting primarily of a $7.7 million impairment charge, net against ARS, $2.4 million of depreciation and amortization of intangible assets, including a write-down of in process research and development, $1.7 million of stock-based compensation expense. In addition, a decrease of $2.6 million in other receivables and prepaid expenses primarily attributable to collection of receivable from the Office of Chief Scientist, an increase of $1.4 million in deferred revenues and an increase of $1.0 million in other payables and accrued expenses, a decrease of $0.3 million in accrues severance pay and a decrease of $0.2 million in other assets offset by an increase of $0.5 million in trade payables and $0.4 million in employees and payroll accruals and an increase of $0.1 million in inventory.

Investing activities. Net cash used in investing activities in 2009 was $3.7 million, primarily attributable to purchasing of property and equipment of $3.6 million and $0.2 million increase in short-term bank deposits and restricted cash and deposits offset by $0.1 million proceeds from sale of property and equipment. Net cash provided by investing activities in 2008 was $12.0 million, primarily attributable to redemption and sale of available-for-sale marketable securities in the amount of $19.6 million, partially offset by $3.8 million attributable to the acquisition of Esphion, $1.7 million of capital investments related primarily to research and development equipment, and a $1.1 million increase in restricted depo sit primarily for securing hedging transactions and $1.0 million investment in short term bank deposits.

We expect that our capital expenditures will total approximately $2.5 million in 2010. We anticipate that these capital expenditures will be primarily related to further investments in lab equipment for research and development, as well as customer support and demo units.

Financing activities. Net cash provided by financing activities in 2009 was $0.5 million, which was attributable to the issuance of share capital through stock options and exercises. Net cash provided by financing activities in 2008 was $0.1 million and was generated by the issuance of share capital through stock options and warrant exercises.

C. Research and Development, Patents and Licenses

Our research and development efforts have benefited from royalty-bearing grants from the Office of the Chief Scientist. For a description of restrictions on the transfer of the technology and with respect to manufacturing rights, see “ITEM 3: Key Information—Risk Factors—The government grants we have received for research and development expenditures restrict our ability to manufacture products and transfer technologies outside of Israel and require us to satisfy specified conditions. If we fail to comply with such restrictions or these conditions, we may be required to refund grants previously received together with interest and penalties, and may be subject to criminal charges.”

Total research and development expenses, before royalty bearing grants, were approximately $11.8 million, $14.6 million and $11.7 million in the years ended December 31, 2007, 2008 and 2009, respectively. Royalty bearing grants amounted to$2.4 million, $2.7 million and $2.4 million in 2007, 2008 and 2009, respectively.

D. Trend Information

See “ITEM 5: Operating and Financial Review and Prospects” above.

B. Compensation of Officers and Directors

We pay each of our outside directors an annual fee of $10,000, paid in four equal installments of $2,500, at the beginning of each calendar quarter with respect to the preceding quarter (with a pro-rata payment for the first and last calendar quarters of service, to the extent the outside director did not serve as such during the entire calendar quarter). Each outside director also was granted upon his or her election and reelection options to purchase 15,000 of our ordinary shares, which vest on a quarterly basis over a period of three years.

During 2009, our officers and directors received, in the aggregate, options to purchase 372,748 ordinary shares under our equity based compensation plans, of which 157,748 options were granted as part of stock option trade-in program in exchange for the participants’ agreement to cancel underwater options that were previously granted to them. These options have a weighted average exercise price of approximately $3.52 and the options will expire ten years after the date the options were granted.

C. Board Practices

Corporate Governance Practices

As a foreign private issuer, we are permitted under NASDAQ Marketplace Rule 5615(a)(3) to follow Israeli corporate governance practices instead of the NASDAQ Stock Market requirements, provided we disclose which requirements we are not following and the equivalent Israeli requirement. See “ITEM 16F: Corporate Governance Requirements” for a discussion of those ways in which our corporate governance practices differ from those required by NASDAQ for domestic companies.

Board of Directors

Terms of Directors

Our articles of association provide that we may have not less than five directors and up to nine directors.

Under our articles of association our directors (other than the outside directors, whose appointment is required under the Companies Law; see “—Outside Directors”) are divided into three classes. Each class of directors consists, as nearly as possible, of one-third of the total number of directors constituting the entire board of directors (other than the outside directors). At each annual general meeting of our shareholders, the election or re-election of directors following the expiration of the term of office of the directors of that class of directors, will be for a term of office that expires on the third annual general meeting following such election or re-election, such that each year the term of office of only one class of directors will expire. Shraga Katz who is a Class I dire ctor, will hold office until our annual meeting of shareholders to be held in 2010. Class II directors, consisting of Dr. Eyal Kishon and Shai Saul, will hold office until our annual meeting of shareholders to be held in 2011. Class III directors, consisting of Yigal Jacoby and Rami Hadar, will hold office until our annual meeting of shareholders to be held in 2012. The directors shall be elected by a vote of the holders of a majority of the voting power present and voting at that meeting. Each director, will hold office until the annual general meeting of our shareholders for the year in which his term expires and until his successor is elected and qualified, unless the tenure of such director expires earlier pursuant to the Companies Law or unless he resigns or is removed from office as described below.

Under the Israeli Companies Law, a director (including an outside director) may be appointed to serve in a public company only if he or she has declared in writing that he or she has the required skills and the ability to dedicate the time required to serve as a director, in view of such company's requirements and scale and during the past five years he or she was not convicted in a final and non-appealable judgment of certain criminal and securities law offenses. Additionally, a director (including an outside director) may be appointed only provided that he or she is not restricted by any court or executive authority from serving as a director, was never declared incompetent by a court, and was either never declared bankrupt or was declared bankrupt but was later discharged by the court. A director that ceases to meet the statutory require ments for his or her appointment must immediately notify us of the same and his or her office will become vacated upon such notice.

Under our articles of association the approval of a special majority of the holders of at least 75.0% of the voting rights present and voting at a general meeting is generally required to remove any of our directors (other than the outside directors) from office. The holders of a majority of the voting power present and voting at a meeting may elect directors in their stead or fill any vacancy, however created, in our board of directors. In addition, vacancies on our board of directors, other than vacancies created by an outside director, may be filled by a vote of a simple majority of the directors then in office. A director so chosen or appointed will hold office until the next annual general meeting of our shareholders, unless earlier removed by the vote of a majority of the directors then in office prior to such annual meeting. See “—O utside Directors” for a description of the procedure for election of outside directors.

Outside Directors

Qualifications of Outside Directors

Under the Israeli Companies Law, companies incorporated under the laws of the State of Israel that are “public companies,” which also includes companies with shares listed on the NASDAQ Stock Market, are required to appoint at least two outside directors. Our outside directors are Ms. Benjamini and Mr. Levy.

A person may not serve as an outside director if at the date of the person’s appointment or within the prior two years, the person, the person’s relatives, entities under the person’s control, any person or entity to whom such person is subordinated (whether directly or indirectly) or the person’s partners or employer, have or had any affiliation with us or any entity controlled by or under common control with us during the prior two years, or which controls us at the time of such person’s appointment.

The term affiliation includes:

an employment relationship;

a business or professional relationship maintained on a regular basis;

control; and

service as an office holder, excluding service as a director in a private company prior to the first offering of its shares to the public if such director was appointed as a director of the private company in order to serve as an outside director following the public offering.

The term relative is defined as spouses, siblings, parents, grandparents, descendants, spouse’s descendants and the spouses of each of these persons.

The term office holder is defined as a director, general manager, chief business manager, deputy general manager, vice general manager, executive vice president, vice president, 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. Each person listed under “—Directors and Senior Management” is an office holder.

No person can serve as an outside director if the person’s position or other business create, or may create, a conflict of interests with the person’s responsibilities as a director or may otherwise interfere with the person’s ability to serve as a director. If at the time an outside director is appointed all current members of the board of directors are of the same gender, then that outside director must be of the other gender.

The Companies Law provides that each outside director must meet certain professional qualifications or have financial and accounting expertise, and that at least one outside director must have financial and accounting expertise. However, if at least one of our directors meets the independence requirements of the Securities Exchange Act of 1934, as amended, and the standards of the NASDAQ Stock Market rules for membership on the audit committee and also has financial and accounting expertise as defined in the Companies Law and applicable regulations, then our outside directors are required to meet the professional qualifications only. Under applicable regulations, a director with financial and accounting expertise is a director who, by reason of his or her education, professional experience and skill, has a high level of proficiency in and understanding of business accounting matters and financial statements. He or she must be able to thoroughly comprehend the financial statements of the company and initiate debate regarding the manner in which financial information is presented. The regulations define a director with the requisite professional qualifications as a director who satisfies one of the following requirements: (1) the director holds an academic degree in either economics, business administration, accounting, law or public administration, (2) the director either holds an academic degree in any other field or has completed another form of higher education in the company’s primary field of business or in an area which is relevant to the office of an outside director, or (3) the director has at least five years of cumulative experience serving in one or more of the following capacities: (a) a senior business management position in a corporation with a substantial scope of business, (b) a senior position in the company’s primary field of business or (c) a senior position in public administration. An outside director that ceases to meet the statutory requirements for his or her appointment must immediately notify us of the same and his or her office will become vacated upon such notice.

Until the lapse of two years from termination of office, a company may not engage an outside director to serve as an office holder and cannot employ or receive professional services for payment from that person, either directly or indirectly, including through a corporation controlled by that person.

Election of Outside Directors

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

the majority of shares voted at the meeting, including at least one-third of the shares of non-controlling shareholders voted at the meeting, excluding abstentions, vote in favor of the election of the outside director; or

the total number of shares of 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 he or she may be reelected to additional terms of three years each by a majority vote at a shareholders’ meeting, subject to the conditions described above for election of outside directors. Reelection to each additional term beyond the first extension must comply with the following additional conditions: (1) the audit committee and, subsequently, the board of directors confirmed that the reelection for an additional term is for the benefit of the company, taking into account the outside director’s expertise and special contribution to the function of the board of directors and its committees, and (2) the general meeting of the company’s shareholders, prior to its approval of the reelection of the outside director, was informed of the term previously served by him or her and of the reasons of the board of directors and audit committee for the extension of the outside director’s term. Outside directors may only be removed by the same majority of shareholders as is required for their election, or by a court, as follows: (1) if the board of directors is made aware of a concern that an outside director has ceased to meet the statutory requirements for his or her appointment, or has violated his or her duty of loyalty to the company, then the board of directors is required to discuss the concern and determine whether it is justified, and if the board of directors determines that the concern is justified, to call a special general meeting of the company’s shareholders, the agenda of which includes the dismissal of the outside director; and (2) at the request of a director or a shareholder of the company, a court may remove an outside director from office if it determines that the outside director has cease d to meet the statutory requirements for his or her appointment, or has violated his or her duty of loyalty to the company, or (3) at the request of the company, a director, a shareholder or a creditor of the company, a court may remove an outside director from office if it determines that the outside director is unable to perform his or her duties on a regular basis, or is convicted of certain offenses set forth in the Companies Law. In addition, an outside director that ceases to meet the statutory requirements for his or her appointment must immediately notify us of the same and his or her office will become vacated upon such notice. If the vacancy of an outside directorship causes the company to have fewer than two outside directors, a company’s board of directors is required under the Companies Law to call a special general meeting of the company’s shareholders as soon as possible to appoint a new outside director. Each committee of a company’s board of directors which is authoriz ed to exercise the board of directors’ authorities is required to include at least one outside director, except for the audit committee, which is required to include all outside director.

An outside director is entitled to compensation as provided in regulations promulgated under the Companies Law and is otherwise prohibited from receiving any other compensation, directly or indirectly, in connection with services provided as an outside director.

NASDAQ Requirements

Under the rules of the NASDAQ Stock Market, a majority of directors must meet the definition of independence contained in those rules. Our board of directors has determined that all of our directors, other than Shraga Katz, Yigal Jacoby and Rami Hadar, meet the independence standards contained in the rules of the NASDAQ Stock Market. We do not believe that any of these directors have a relationship that would preclude a finding of independence under these rules and, in reaching its determination, our board of directors determined that the other relationships that these directors have with us do not impair their independence.

Audit Committee

Companies Law Requirements

Under the Companies Law, the board of directors of any public company must also appoint an audit committee comprised of at least three directors including all of the outside directors, but excluding the:

chairman of the board of directors;

controlling shareholder or a relative of a controlling shareholder; and

any director employed by the company or who provides services to the company on a regular basis.

NASDAQ Requirements

Under the NASDAQ Stock Market rules, we are required to maintain an audit committee consisting of at least three independent directors, all of whom are financially literate and one of whom has accounting or related financial management expertise. Our audit committee members are required to meet additional independence standards, including minimum standards set forth in rules of the Securities and Exchange Commission and adopted by the NASDAQ Stock Market.

Approval of Transactions with Office Holders and Controlling Shareholders

The approval of the audit committee is required to effect specified actions and transactions with office holders and controlling shareholders. The term controlling shareholder means a shareholder with the ability to direct the activities of the company, other than by virtue of being an office holder. A shareholder is presumed to be a controlling shareholder if the shareholder holds 50.0% or more of the voting rights in a company or has the right to appoint the majority of the directors of the company or its general manager. For the purpose of approving transactions with controlling shareholders, the term also includes any shareholder that holds 25.0% or more of the voting rights of the company if the company has no shareholder that owns more than 50.0% of its voting rights. For purposes of determining th e holding percentage stated above, two or more shareholders who have a personal interest in a transaction that is brought for the company’s approval are deemed as joint holders. The 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 them was present at the meeting at which the approval was granted.

Audit Committee Role

Our board of directors has adopted an audit committee charter setting forth the responsibilities of the audit committee consistent with the rules of the Securities and Exchange Commission and the NASDAQ Global Market rules, which include:

retaining and terminating the company’s independent auditors, subject to shareholder ratification;

pre-approval of audit and non-audit services provided by the independent auditors; and

approval of transactions with office holders and controlling shareholders, as described above, and other related-party transactions.

Additionally, under the Companies Law, the role of the audit committee is to identify irregularities in the business management of the company in consultation with the internal auditor or the company’s independent auditors and suggest an appropriate course of action to the board of directors, to approve related-party actions and transactions per the instructions of the Companies Law and to approve the yearly or periodic work plan proposed by the internal auditor to the extent required. The audit committee charter states that in fulfilling this role the committee is entitled to rely on interviews and consultations with our management, our internal auditor and our independent auditor, and is not obligated to conduct any independent investigation or verification.

Our audit committee consists of our directors, Ms. Nurit Benjamini, Mr. Steven Levy and Dr. Eyal Kishon. The financial expert on the audit committee pursuant to the definition of the Securities and Exchange Commission is Ms. Benjamini.

Compensation and Nominating Committee

We have established a compensation and nominating committee consisting of our directors, Dr. Eyal Kishon, Ms. Nurit Benjamini and Mr. Shai Saul. This committee also oversees matters related to our corporate governance practices. Our board of directors has adopted a compensation and nominating committee charter setting forth the responsibilities of the committee consistent with the NASDAQ Stock Market rules, which include:

determining the compensation of our Chief Executive Officer and other executive officers;

granting options to our employees and the employees of our subsidiaries;

recommending candidates for nomination as members of our board of directors; and

developing and recommending to the board corporate governance guidelines and a code of business ethics and conduct in accordance with applicable laws.

Internal Auditor

Under the Companies Law, the board of directors of a public company must appoint an internal auditor nominated by the audit committee. The role of the internal auditor is, among other things, to examine whether a company’s actions comply with applicable law and orderly business procedure. Under the Companies Law, the internal auditor may be an employee of the company but not an interested party or an office holder or a relative of an interested party or an office holder, nor may the internal auditor be the company’s independent auditor or the representative of the same. An interested party is defined in the Companies Law as a holder of 5.0% or more of the issued share capital or voting power in a company, any person or entity who has the right to designate one director or more or the chief ex ecutive officer of the company or any person who serves as a director or as a chief executive officer. In February 2007, our board of directors approved the appointment of the firm of Haikin, Rubin, Cohen & Gilboa as the internal auditor of the Company.

Exculpation, Insurance and Indemnification of Office Holders

Under the Companies Law, a company may not exculpate an office holder from liability for a breach of the duty of loyalty. However, a company may approve an act performed in breach of the duty of loyalty of an office holder provided that the office holder acted in good faith, the act or its approval does not harm the company, and the office holder discloses the nature of his or her personal interest in the act and all material facts and documents a reasonable time before discussion of the approval. An Israeli company may exculpate an office holder in advance from liability to the company, in whole or in part, for damages caused to the company as a result of a breach of duty of care but only if a provision authorizing such exculpation is inserted in its articles of association. Our articles of association include such a provision. An Israeli company may not exculpate a director for liability arising out of a prohibited dividend or distribution to shareholders.

An Israeli company may indemnify an office holder in respect of certain liabilities either in advance of an event or following an event provided a provision authorizing such indemnification is inserted in its articles of association. Our articles of association contain such an authorization. An undertaking provided in advance by an Israeli company to indemnify an office holder with respect to a financial liability imposed on him or her in favor of another person pursuant to a judgment, settlement or arbitrator’s award approved by a court must be limited to events which in the opinion of the board of directors can be foreseen based on the company’s activities when the undertaking to indemnify is given, and to an amount or according to criteria determined by the board of directors as reasonable under the circumstances, and such undertaking shall detail the above mentioned events and amount or criteria. In addition, a company may undertake in advance to indemnify an office holder against the following liabilities incurred for acts performed as an office holder:

reasonable litigation expenses, including attorneys’ fees, incurred by the office holder as a result of an investigation or proceeding instituted against him or her by an authority authorized to conduct such investigation or proceeding, provided that (i) no indictment was filed against such office holder as a result of such investigation or proceeding; and (ii) no financial liability, such as a criminal penalty, was imposed upon him or her as a substitute for the criminal proceeding as a result of such investigation or proceeding or, if such financial liability was imposed, it was imposed with respect to an offense that does not require proof of criminal intent; and

reasonable litigation expenses, including attorneys’ fees, incurred by the office holder or imposed by a court in proceedings instituted against him or her by the company, on its behalf or by a third party or in connection with criminal proceedings in which the office holder was acquitted or as a result of a conviction for an offense that does not require proof of criminal intent.

An Israeli company may insure an office holder against the following liabilities incurred for acts performed as an office holder if and to the extent provided in the company’s articles of association:

a breach of duty of loyalty to the company, to the extent that the office holder acted in good faith and had a reasonable basis to believe that the act would not prejudice the company;

a breach of duty of care to the company or to a third party, including a breach arising out of the negligent conduct of the office holder; and

a financial liability imposed on the office holder in favor of a third party.

An Israeli company may not indemnify or insure an office holder against any of the following:

a breach of duty of loyalty, except to the extent that the office holder acted in good faith and had a reasonable basis to believe that the act would not prejudice the company;

a breach of duty of care committed intentionally or recklessly, excluding a breach arising out of the negligent conduct of the office holder;

an act or omission committed with intent to derive illegal personal benefit; or

a fine or forfeit levied against the office holder.

Under the Companies Law, exculpation, indemnification and insurance of office holders must be approved by our audit committee and our board of directors and, in respect of our directors, by our shareholders.

Our articles of association allow us to indemnify and insure our office holders to the fullest extent permitted by the Companies Law. Our office holders are currently covered by a directors and officers’ liability insurance policy. In May 2007, we and certain of our officers and directors were named as defendants in a number of purported securities class action lawsuits filed in the United States District Court for the Southern District of New York and that were consolidated to “In re Allot Communications Ltd. Securities Litigation.” under Master File No. 07-cv-03455 (RJH). See “ITEM 8: Financial Information—Consolidated Statements and Other Financial Information—Legal Proceedings.&# 8221; As of the date of this annual report, no other claims for directors and officers’ liability insurance have been filed under our policies and we are not aware of any pending or threatened litigation or proceeding involving any of our directors or officers in which indemnification is sought.

We have entered into agreements with each of our directors and with certain of our office holders exculpating them, to the fullest extent permitted by law, from liability to us for damages caused to us as a result of a breach of duty of care, and undertaking to indemnify them to the fullest extent permitted by law. This indemnification is limited to events determined as foreseeable by the board of directors based on our activities, and to an amount or according to criteria determined by the board of directors as reasonable under the circumstances, and the insurance is subject to our discretion depending on its availability, effectiveness and cost. The current maximum amount set forth in such agreements is the greater of (1) with respect to indemnification in connection with a public offering of our secur ities, the gross proceeds raised by us and/or any selling shareholder in such public offering, and (2) with respect to all permitted indemnification, including a public offering of our securities, an amount equal to 50% of the our shareholders’ equity on a consolidated basis, based on our most recent financial statements made publicly available before the date on which the indemnity payment is made.

In the opinion of the U.S. Securities and Exchange Commission, however, indemnification of directors and office holders for liabilities arising under the Securities Act is against public policy and therefore unenforceable.

D. Employees

As of December 31, 2009, we had 252 employees of whom 170 were based in Israel, 29 in the United States and the remainder in Asia and Europe. The breakdown of our employees by department is as follows:

	December 31,
Department	2007		2008		2009

Manufacturing and operations		16		16		16
Research and development		92		94		92
Sales, marketing, service and support		102		102		114
Management and administration		32		31		30

Total		242		243		252

Under applicable Israeli law, we and our employees are subject to protective labor provisions such as restrictions on working hours, minimum wages, minimum vacation, sick pay, severance pay and advance notice of termination of employment as well as equal opportunity and anti-discrimination laws. Orders issued by the Israeli Ministry of Industry, Trade and Labor make certain industry-wide collective bargaining agreements applicable to us. These agreements affect matters such as cost of living adjustments to salaries, length of working hours and week, recuperation, travel expenses, and pension rights. Our employees are not represented by a labor union. We provide our employees with benefits and working conditions which we believe are competitive with benefits and working conditions provided by similar comp anies in Israel. We have never experienced labor-related work stoppages and believe that our relations with our employees are good.

As used in this table, “beneficial ownership” means the sole or shared power to vote or direct the voting or to dispose or direct the disposition of any security. For purposes of this table, a person is deemed to be the beneficial owner of securities that can be acquired within 60 days from April 1, 2010 through the exercise of any option or warrant. Ordinary shares subject to options or warrants that are currently exercisable or exercisable within 60 days are deemed outstanding for computing the ownership percentage of the person holding such options or warrants, but are not deemed outstanding for computing the ownership percentage of any other person. The amounts and percentages are based upon 22,551,520 ordinary shares outstanding as of April 1, 2010.

Consists of 2,331,593 shares held by the Tamir Fishman Ventures and options to purchase 22,500 shares held by Shai Saul. Mr. Saul is a managing partner of Tamir Fishman and, by virtue of his position, may be deemed to have voting and investment power, and thus beneficial ownership, with respect to the shares held by the Tamir Fishman Ventures. Mr. Saul disclaims such beneficial ownership except to the extent of his pecuniary interest therein.

Consists of 835,410 shares held by Odem Rotem Holdings Ltd., a company wholly-owned and controlled by Yigal Jacoby, 58,548 shares jointly held by Yigal Jacoby and his spouse, Anat Jacoby, and an option to purchase 380,994 shares held by Odem Rotem Holdings. Also consists of a right held by Mr. Jacoby to purchase 246,479 shares currently held by a trustee. See “ITEM 7: Major Shareholders and Related Party Transactions—Related Party Transactions—Escrow Agreement with Yigal Jacoby.”

Our directors and executive officers hold, in the aggregate, options exercisable into 2,243,063 ordinary shares. The 2,243,063 options have a weighted average exercise price of approximately $3.08 per share and have expiration dates until 2019.

Share Option Plans

We have adopted four share option plans and, as of April 1, 2010, we had 4,759,373 ordinary shares reserved for issuance under these plans, with respect to which (i) options to purchase 4,067,457 ordinary shares at a weighted average exercise price of $3.12 per share were outstanding, and (ii) options to purchase 2,245,101 ordinary shares were already exercised by certain of the grantees and such shares were issued by us. As of April 1, 2010, options to purchase 2,213,058 ordinary shares were vested and exercisable.

We will only grant options or other equity incentive awards under the 2006 Incentive Compensation Plan, although previously-granted options will continue to be governed by our other plans.

2006 Incentive Compensation Plan

The 2006 plan is intended to further our success by increasing the ownership interest of certain of our and our subsidiaries’ employees, directors and consultants and to enhance our and our subsidiaries’ ability to attract and retain employees, directors and consultants.

The number of ordinary shares that we may issue under the 2006 plan will increase on the first day of each fiscal year during the term of the 2006 plan, in each case in an amount equal to the lesser of (i) 1,000,000 shares, (ii) 3.5% of our outstanding ordinary shares on the last day of the immediately preceding year, or (iii) an amount determined by our board of directors. The number of shares subject to the 2006 plan is also subject to adjustment if particular capital changes affect our share capital. Ordinary shares subject to outstanding awards under the 2006 plan or our 2003 plan or 1997 plans that are subsequently forfeited or terminated for any other reason before being exercised will again be available for grant under the 2006 plan. As of April 1, 2010, options or other awards to purchase 3,560,046 ordinary shares had been granted under the 2006 plan and 648,702 remained available for future options or other awards.

Israeli participants in the 2006 plan may be granted options subject to Section 102 of the Israeli Income Tax Ordinance. Section 102 of the Israeli Income Tax Ordinance, allows employees, directors and officers, who are not controlling shareholders and are considered Israeli residents to receive favorable tax treatment for compensation in the form of shares or options. Our non-employees service providers and controlling shareholders may only be granted options under another section of the Tax Ordinance, which does not provide for similar tax benefits. Section 102 includes two alternatives for tax treatment involving the issuance of options or shares to a trustee f or the benefit of the grantees and also includes an additional alternative for the issuance of options or shares directly to the grantee. The most favorable tax treatment for the grantees is under Section 102(b)(2) of the Tax Ordinance, the issuance to a trustee under the “capital gain track.” However, under this track we are not allowed to deduct an expense with respect to the issuance of the options or shares. Any stock options granted under the 2006 plan to participants in the United States will be either “incentive stock options,” which may be eligible for special tax treatment under the U.S. Internal Revenue Code of 1986, or options other than incentive stock options (referred to as “nonqualified stock options”), as determined by our compensation and nominating committee and stated in the option agreement.

Our compensation and nominating committee administers the 2006 plan and it will select which of our and our subsidiaries’ and affiliates’ eligible employees, directors and/or consultants shall receive options or other awards under the 2006 plan and will determine the terms of the grant, including, exercise prices, method of payment, vesting schedules, acceleration of vesting and the other matters necessary in the administration of the plan.

If we undergo a change of control, as defined in the 2006 plan, subject to any contrary law or rule, or the terms of any award agreement in effect before the change of control, (a) the compensation and nominating committee may, in its discretion, accelerate the vesting, exercisability and payment, as applicable, of outstanding options and other awards; and (b) the compensation and nominating committee, in its discretion, may adjust outstanding awards by substituting ordinary shares or other securities of any successor or another party to the change of control transaction, or cash out outstanding options and other awards, in any such case, generally based on the consideration received by our shareholders in the transaction.

Allot Communications Ltd. Key Employee Share Incentive Plan (2003)

Our 2003 share option plan provides for the grant of options to our and our affiliates’ employees, directors, officers, consultants, advisers and service providers. As of April 1, 2010, there were outstanding options to purchase 1,548,650 ordinary shares under the plan, of which options to purchase 1,538,506 ordinary shares were vested and exercisable and options to purchase 1,441,367 ordinary shares were already exercised for ordinary shares. We no longer grant options under this plan, and ordinary shares underlying any option granted under this plan that terminates without exercise become available for future issuance under our 2006 plan.

The terms of the 2003 plan are in compliance with Section 102 of the Israeli Income Tax Ordinance, which allows employees, directors and officers, who are not controlling shareholders and are considered Israeli residents to receive favorable tax treatment for compensation in the form of shares or options. Our non-employees service providers and controlling shareholders may only be granted options under another section of the Tax Ordinance, which does not provide for similar tax benefits.

We have elected to issue our options under the capital gain track and, accordingly, all options granted under this plan to Israeli residents have been granted under the capital gain track. Section 102 also provides for an income tax track, under which, among other things, the benefits to the employees would be taxed as ordinary income, we would be allowed to recognize expenses for tax purposes and the minimum holding period for the trustee will be twelve months from the end of the calendar year in which such options are granted, and if granted after January 1, 2006, twelve months after the date of grant. In order to comply with the terms of the capital gain track, all options, as well as the ordinary shares issued upon exercise of these opti ons and other shares received subsequently following any realization of rights with respect to such options, such as stock dividends and stock splits are granted to a trustee and should be held by the trustee for the lesser of thirty months from the date of grant, or two years following the end of the tax year in which the options were granted and if granted after January 1, 2006 only two years after the date of grant. Under this plan, all options, whether or not granted pursuant to said Section 102, the ordinary shares issued upon their exercise and other shares received subsequently following any realization of rights are issued to a trustee.

The plan is administered by our board of directors which has delegated certain responsibilities to our compensation and nomination committee.

In the event of our being acquired by means of merger with or into another entity, in which our outstanding shares are exchanged for securities or other consideration issued, or caused to be issued, by the acquiring company or its subsidiary, or in the event of the sale of all or substantially all of our assets, to the extent it has not been previously exercised, each vested or unvested option will terminate immediately prior to the consummation of such transaction. The plan further provides that, in the event of our consolidation or merger with or into another corporation, the compensation committee may, in its absolute discretion and without obligation, agree that instead of termination: (i) each unexercised option, if possible, will be assumed or an equivalent option will be substituted by our su ccessor corporation or a parent or subsidiary of our successor corporation; or (ii) we will pay to the grantee an amount equivalent to the valuation of the grantee’s unexercised options on an as converted basis at that time.

Allot Communications Ltd. Key Employees Share Incentive Plan and Key Employees of Subsidiaries and Consultants Share Incentive Plan (1997)

Our Key Employees Share Incentive Plan, adopted in 1997, provides for the grant of options to any of our directors, officers and employees, and our Key Employees of Subsidiaries and Consultants Share Incentive Plan, also adopted in 1997, provides for the grant of options to any of our or our subsidiaries’ directors, officers, employees, or consultants. The terms of both plans are identical, except that the grant of options under the first plan was made in compliance with the provisions of Section 102 of the Tax Ordinance, as was in effect in 1997 and prior to its amendments in 2003, which allows employees who are considered Israeli residents to receive favorable tax treatment.

As of April 1, 2010, there were outstanding options to purchase 5,551 ordinary shares under the two plans, all of which were vested, and options to purchase 760,520 ordinary shares that were already exercised for ordinary shares. We no longer grant options under these plans, and ordinary shares underlying any option granted under these plans that terminate without exercise become available for future issuance under our 2006 plan.

The plans are administered by our compensation and nominating committee.

B. Related Party Transactions

Our policy is to enter into transactions with related parties on terms that, on the whole, are no more favorable, or no less favorable, than those available from unaffiliated third parties. Based on our experience in the business sectors in which we operate and the terms of our transactions with unaffiliated third parties, we believe that all of the transactions described below met this policy standard at the time they occurred.

Registration Rights

We have entered into an amended and restated investors rights agreement with certain of our shareholders, pursuant to which such holders are entitled to certain registration rights as described below. This amount does not include shares issuable upon the exercise of options and warrants, which are also entitled to registration rights as described under “— Registration Rights—Certain Options and Warrants.” In accordance with such agreement, the following entities, which beneficially own more than 5.0% of our ordinary shares, are entitled to registration rights: the Tamir Fishman Ventures; the Gemini Group; the Partech International Group; and our founder and member of the board of directors, Yigal Jacoby and Odem Rotem Holdings, a co mpany wholly-owned and controlled by Mr. Jacoby.

Demand registration rights. We are required to file a registration statement in respect of ordinary shares held by our former preferred shareholders as follows:

two registrations at the request of one or more of our shareholders holding ordinary shares representing in the aggregate a majority of ordinary shares resulting from conversion of our Series A preferred shares, Series B preferred shares, collectively, referred to as the B Registrable Securities, and Series C preferred shares and all ordinary shares issued in respect of such shares;

one registration at the request of one of more of our shareholders holding ordinary shares representing in the aggregate a majority of ordinary shares resulting from conversion of our Series D preferred shares and all ordinary shares issued in respect of such shares;

one registration at the request of one of more of our shareholders holding ordinary shares representing in the aggregate a majority of ordinary shares resulting from conversion of our Series E preferred shares and all ordinary shares issued in respect of such shares; and

provided that (1) the aggregate proceeds from any such registration are estimated in good faith to be in excess of $5.0 million and (2) we are not required to effect a registration within 180 days after the effective date of our initial public offering or a registration statement for any subsequent offering.

Following a request to effect a registration by our shareholders as described above, we are required to offer the other shareholders that are entitled to registration rights an opportunity to include their shares in the registration statement. In the event that the managing underwriter advises the registering shareholders in writing that marketing factors require a limitation on the number of shares that can be included in the registration statement, certain preferences will apply with respect to the inclusion of the registrable securities.

Registration on Form F-3. Shareholders holding registrable securities may request that we register such registrable securities on Form F-3, provided that each such registration generates proceeds of at least $2.0 million. This right may be exercised up to twice in any twelve-month period. We are required to give notice of any such request to the other holders of registrable securities and offer them an opportunity to include their shares in the registration statement. In the event that the managing underwriter advises in writing that marketing factors require a limitation on the number of shares that can be included in the registration statement, the shares will be included in the registration statement in a n agreed order of preference between the shareholders holding registrable securities.

Piggyback registration rights. Shareholders holding registrable securities also have the right to request that we include their registrable securities in any registration statements filed by us in the future for the purposes of a public offering, subject to specified exceptions. In the event that the managing underwriter advises in writing that marketing factors require a limitation on the number of shares that can be included in the registration statement, the shares will be included in the registration statement in an agreed order of preference between the shareholders holding registrable securities.

Termination. All registration rights granted to holders of registrable securities will terminate on the fifth anniversary of the closing of our initial public offering and, with respect to any of our holders of registrable securities, when the shares held by such shareholder can be sold within a ninety-day period under Rule 144.

Expenses. We will pay all expenses in carrying out the above registrations.

Certain options. We have also granted the following registration rights with respect to246,479 ordinary shares that have been issued, but are held in trust for the benefit of our founder and member of the board of directors, Yigal Jacoby, pending his payment of the purchase price of such shares, will be entitled, upon the payment of the purchase price, to the same registration rights as the Series A preferred shares.

Agreements with Directors and Officers

Employment of Shraga Katz. In June 2008, we entered into an agreement with Shraga Katz governing the terms of his employment with us for the provision of consulting services. Under the terms of the agreement, Mr. Katz was required to devote 20% of his time to his position with us. In November 2008, Mr. Katz was elected as the Chairman of our board of directors and his monthly compensation was increased. The agreement contains standard employment provisions, including provisions relating to confidentiality and assignment of inventions. We may terminate Mr. Katz’s employment on a prior notice pursuant to applicable law, or we may terminate Mr. Katz’s employment without notice if we give a pay in lieu of notice.

Employment of Yigal Jacoby. In October 2006, we entered into an agreement with Yigal Jacoby governing the terms of his employment with us for the provision of management and guidance services with regard to our strategy, long term vision and key objectives. Under the terms of the agreement, Mr. Jacoby was required to devote 75% of his time to his position with us. In November 2008, the agreement was amended such that Mr. Jacoby’s scope of engagement was reduced to 12.5% of a full time position and his monthly compensation was reduced. The agreement contains standard employment provisions, including provisions relating to confidentiality and assignment of inventions. We may terminate Mr. Jacoby’s employment on thirty days’ prior notice, or we may terminate Mr. Jacoby’s employment without notice if we give him thirty days’ pay in lieu of notice.

Prior to his transition to a direct employment relationship, Mr. Jacoby provided substantially identical services to us pursuant to a consulting agreement, dated December 2001. The agreement was terminated in October 2006. The agreement contained standard confidentiality provisions that survived the agreement’s termination.

Escrow Agreement with Yigal Jacoby. A right to purchase 246,479 ordinary shares was granted to Mr. Jacoby in connection with our Series A financing. The shares are issued, but are held in trust for the benefit of the Mr. Jacoby pursuant to an escrow agreement entered into on January 28, 1998, amended on October 26, 2006 and November 13, 2008, by and among the Company, Mr. Jacoby and an escrow agent. Pursuant to the terms of this agreement, the escrow agent is holding such shares for which Mr. Jacoby has paid nominal value. While these shares are held in trust, neither Mr. Jacoby nor the trustee has voting or economic rights with respect to such shares. Mr. Jacoby may exercise his right to purchase the shares in tr ust, in whole or in part, by paying any portion of the full $600,000 purchase price (less $475 previously paid in respect of the nominal value of the shares) for the respective portion of the shares. Mr. Jacoby has the right to pay any portion of the purchase price for the respective portion of shares by “net payment” of his right to purchase. Mr. Jacoby’s right to purchase expires upon November 15, 2010. See Note 10c to our consolidated financial statements for additional information.

Technical Training Services Agreement with Experteam. We have received technical writing services from Experteam Ltd., a company owned and controlled by the wife of our founder and member of the board of directors, Yigal Jacoby. We began using Experteam in 2004 and our expenses incurred in connection with the engagement of Experteam were approximately $36,000 in 2007, $39,848 in 2008 and $6,133 in 2009.

Employment Agreements. We have entered into employment agreements with each of our officers who work for us as employees. These agreements all contain provisions standard for a company in our industry regarding noncompetition, confidentiality of information and assignment of inventions. The enforceability of covenants not to compete in Israel may be limited.

Exculpation, Indemnification and Insurance. Our articles of association permit us to exculpate, indemnify and insure our office holders to the fullest extent permitted by the Companies Law.

Legal Proceedings

On May 1, 2007, a securities class action complaint, Brickman Investment Inc. v. Allot Communications Ltd. et al., was filed in the United States District Court for the Southern District of New York. At least three substantially similar complaints were filed in the same court after the original action was filed. We and certain of our directors and officers are named as defendants. The securities class action complaints allege that the defendants violated Sections 11 and 15 of the Securities Act of 1933 by making false and misleading statements and omissions in our registration statement for our initial public offering in November 2006. The claims are purportedly brought on behalf of persons who purchased our s tock pursuant to and/or traceable to the initial public offering on or about November 15, 2006 through April 2, 2007. The plaintiffs seek unspecified compensatory damages against the defendants, as well as attorney’s fees and costs. Motions for consolidation and for appointment of lead plaintiff were filed on July 2, 2007 and were decided on March 27, 2008, with an order granting consolidation and appointing co-lead plaintiffs. The Consolidated Amended Compliant was served on June 9, 2008. The defendants moved to dismiss the Consolidated Amended Compliant on August 8, 2008. While the defendants’ motion to dismiss was still pending, the parties reached on March 31, 2010 an agreement in principle to settle this litigation. Pursuant to the terms of the agreement, the Company will pay to the plaintiffs, for the benefit of the class members, $1.3 million in cash, which amount is to be funded by our insurance carrier. The settlement contemplated therein is conditional upon approval by the co urt and other contingencies. There is no assurance that final court approval will be obtained. If such approval is not obtained, the parties to this litigation may attempt to reach agreement on alternative settlement terms or resume the litigation. The Company has recorded a liability in its financial statements for the proposed amount of the settlement. In addition, because the insurance carrier has agreed to pay the entire settlement amount and recovery from the insurance carrier is probable, a receivable has also been recorded for the same amount. Accordingly, there is no impact to the Company’s statements of operations or cash flows because the amounts of the settlement and the insurance recovery fully offset each other.

We may, from time to time in the future be involved in legal proceedings in the ordinary course of business.

Dividends

We have never declared or paid any cash dividends on our ordinary shares and we do not anticipate paying any cash dividends on our ordinary shares in the future. We currently intend to retain all future earnings to finance our operations and to expand our business. Any future determination relating to our dividend policy will be made at the discretion of our board of directors and will depend on a number of factors, including future earnings, capital requirements, financial condition and future prospects and other factors our board of directors may deem relevant.

B. Significant Changes

Since the date of our audited financial statements included elsewhere in this annual report, there have not been any significant changes in our financial position.

A person wishing to acquire shares of a public Israeli company and who would as a result hold over 90.0% of the target company’s issued and outstanding share capital is required by the Companies Law to make a tender offer to all of the company’s shareholders for the purchase of all of the issued and outstanding shares of the company. A person wishing to acquire shares of a public Israeli company and who would as a result hold over 90.0% of the issued and outstanding share capital of a certain class of shares is required to make a tender offer to all of the shareholders who hold shares of the same class for the purchase of all of the issued and outstanding shares of the same class. If the shareholders who do not accept the offer hold less than 5.0% of the issued and outstanding share capital of the company or of the applicable class, all of the shares that the acquirer offered to purchase will be transferred to the acquirer by operation of law. However, a shareholder that had its shares so transferred may, within three months from the date of acceptance of the tender offer, petition the court to determine that tender offer was for less than fair value and that the fair value should be paid as determined by the court. If the shareholders who did not accept the tender offer hold at least 5.0% of the issued and outstanding share capital of the company or of the applicable class, the acquirer may not acquire shares of the company that will increase its holdings to more than 90.0% of the company’s issued and outstanding share capital or of the applicable class from shareholders who accepted the tender offer.

Special Tender Offer. The Companies Law provides that an acquisition of shares of a public Israeli company must be made by means of a special tender offer if as a result of the acquisition the purchaser would become a holder of at least 25.0% of the voting rights in the company. This rule does not apply if there is already another holder of at least 25.0% of the voting rights in the company. Similarly, the 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 holder of more than 45.0% of the voting rights in the company, if there is no other shareholder of the company who holds more than 45.0% of th e voting rights in the company. These requirements do not apply if the acquisition (i) occurs in the context of a private placement by the company that received shareholder approval, (ii) was from a shareholder holding at least 25.0% of the voting rights in the company and resulted in the acquirer becoming a holder of at least 25.0% of the voting rights in the company or (iii) was from a holder of more than 45.0% of the voting rights in the company and resulted in the acquirer becoming a holder of more than 45.0% of the voting rights in the company. The special tender offer may be consummated only if at least 5.0% of the voting rights attached to the company’s outstanding shares will be acquired by the offeror.

In the event that a special tender offer is made, a company’s board of directors is required to express its opinion on the advisability of the offer, or shall abstain from expressing any opinion if it is unable to do so, provided that it gives the reasons for its abstention. An office holder in a target company who, in his or her capacity as an office holder, performs an action the purpose of which is to cause the failure of an existing or foreseeable special tender offer or is to impair the chances of its acceptance, is liable to the potential purchaser and shareholders for damages, unless such office holder acted in good faith and had reasonable grounds to believe he or she was acting for the benefit of the company. However, office holders of the target company may negotiate with the potential purchaser in order to improve the terms of the spe cial tender offer, and may further negotiate with third parties in order to obtain a competing offer.

If a special tender offer was accepted by a majority of the shareholders who announced their stand on such offer, then shareholders who did not announce their stand or who had objected to the offer may accept the offer within four days of the last day set for the acceptance of the offer.

In the event that a special tender offer is accepted, then the purchaser or any person or entity controlling it or under common control with the purchaser or such controlling person or entity shall refrain of making a subsequent tender offer for the purchase of shares of the target company and cannot execute a merger with the target company for a period of one year from the date of the offer, unless the purchaser or such person or entity undertook to effect such an offer or merger in the initial special tender offer.

Merger. The Companies Law permits merger transactions if approved by each party’s board of directors and, unless certain requirements described under the Companies Law are met, a certain percentage of each party’s shareholders. The board of directors of a merging company is required pursuant to the Companies Law to discuss and determine whether in its opinion there exists a reasonable concern that as a result of a proposed merger, the surviving company will not be able to satisfy its obligations towards its creditors, such determination taking into account the financial status of the merging companies. If the board has determined that such a concern exists, it may not approve a proposed merger. Following th e approval of the board of directors of each of the merging companies, the boards must jointly prepare a merger proposal for submission to the Israeli Registrar of Companies.

Under the 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 our shares (including the separate vote of each class of shares of the party to the merger which is not the surviving entity) present, in person, by proxy or by written ballot, at a general meeting and voting on the transaction. In determining whether the required majority has approved the merger, if shares of the company are held by the other party to the merger, or by any person holding at least 25.0% of the voting rights or 25.0% of the means of appointing directors or the general manager of the other party to the merger, then a vote against the merger by holders of the majority of the shares present and voting, excluding shares held by t he other party or by such person, or any person or entity acting on behalf of, related to or controlled by either of them, is sufficient to reject the merger transaction. If the transaction would have been approved but for the separate approval of each class or the exclusion of the votes of certain shareholders as provided above, a court may still approve the merger upon the request of holders of at least 25.0% of the voting rights of a company, if the court holds that the merger is fair and reasonable, taking into account the value of the parties to the merger and the consideration offered to the shareholders.

Under the Companies Law, each merging company must inform its secured creditors of the proposed merger plans. Creditors are entitled to notice of the merger pursuant to the regulations adopted under the Companies Law. 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 any of the parties to the merger, and may further give instructions to secure the rights of creditors.

In addition, a merger may not be completed unless at least fifty days have passed from the date that a proposal for approval of the merger was filed with the Israeli Registrar of Companies and thirty days from the date that shareholder approval of both merging companies was obtained.

Anti-Takeover Measures

Undesignated preferred stock. The Companies Law allows us to create and issue shares having rights different to those attached to our ordinary shares, including shares providing certain preferred or additional rights to voting, distributions or other matters and shares having preemptive rights. We do not have any authorized or issued shares other than ordinary shares. In the future, if we do create and issue a class of shares other than ordinary shares, such class of shares, depending on the specific rights that may be attached to them, may delay or prevent a takeover or otherwise prevent our shareholders from realizing a potential premium over the market value of their ordinary shares. The authorization of a new class of shares will require an amendment to our articles of association which requires the prior approval of a simple majority of our shares represented and voted at a general meeting.

Supermajority voting. Our articles of association require the approval of the holders of at least two thirds of our combined voting power to effect certain amendments to our articles of association.

Classified board of directors. Our articles of association provide for a classified board of directors. See “ITEM 6: Directors, Senior Management and Employees—Board Practices—Term of Directors.”

Transfer Agent and Registrar

The transfer agent and registrar for our ordinary shares is American Stock Transfer & Trust Company. Its address is 59 Maiden Lane, New York, New York 10038 and its telephone number is (718) 921-8200.

D. Exchange Controls

In 1998, Israeli currency control regulations were liberalized significantly, so that Israeli residents generally may freely deal in foreign currency and foreign assets, and non-residents may freely deal in Israeli currency and Israeli assets. There are currently no Israeli currency control restrictions on remittances of dividends on the ordinary shares or the proceeds from the sale of the shares provided that all taxes were paid or withheld; however, legislation remains in effect pursuant to which currency controls can be imposed by administrative action at any time.

Non-residents of Israel may freely hold and trade our securities. 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 ordinary shares by non-residents, except that such restrictions may exist with respect to citizens of countries which are in a state of war with Israel. Israeli residents are allowed to purchase our ordinary shares.

E. Taxation

Israeli Tax Considerations and Government Programs

The following is a general discussion only and is not exhaustive of all possible tax considerations. It is not intended, and should not be construed, as legal or professional tax advice and should not be relied upon for tax planning purposes. In addition, this discussion does not address all of the tax consequences that may be relevant to purchasers of our ordinary shares in light of their particular circumstances, or certain types of purchasers of our ordinary shares subject to special tax treatment. Examples of this kind of investor include residents of Israel and traders in securities who are subject to special tax regimes not covered in this discussion. Each individual/entity should consult its own tax or legal advisor as to the Israeli tax consequences of the purchase, ownership and disposition of o ur ordinary shares.

To the extent that part of the discussion is based on new tax legislation, which has not been subject to judicial or administrative interpretation, we cannot assure that the tax authorities or the courts will accept the views expressed in this section.

The following summary describes the current tax structure applicable to companies in Israel, with special reference to its effect on us. The following also contains a discussion of the material Israeli tax consequences to holders of our ordinary shares.

General Corporate Tax Structure in Israel

Taxable income of Israeli companies is subject to tax at the rate of 27% in 2008, 26% in 2009, and 25% in 2010 and thereafter. In July 2009, Israel's Parliament (the Knesset) passed the Economic Efficiency Law (Amended Legislation for Implementing the Economic Plan for 2009 and 2010), 2009, which prescribes, among other things, an additional gradual reduction in the Israeli corporate tax rate and real capital gains tax rate starting from 2011 to the following tax rates: 2011 - 24%, 2012 - 23%, 2013 - 22%, 2014 - 21%, 2015 - 20%, 2016 and thereafter - 18%.

Following an additional amendment to the Tax Ordinance, which came into effect on January 1, 2009, an Israeli corporation may elect a 5% rate of corporate tax (instead of 25%) for income from dividend distributions received from a foreign subsidiary which is used in Israel in 2009, or within one year after actual receipt of the dividend, whichever is later. The 5% tax rate is subject to various conditions, which include conditions with regard to the identity of the corporation that distributes the dividends, the source of the dividend, the nature of the use of the dividend income, and the period during which the dividend income will be used in Israel.

Tax Benefits and Grants for Research and Development

Israeli tax law allows, under certain conditions, a tax deduction for expenditures, including capital expenditures, for the year in which they are incurred. Expenditures are deemed related to scientific research and development projects, if:

The expenditures are approved by the relevant Israeli government ministry, determined by the field of research;

The research and development must be for the promotion of the company; and

The research and development is carried out by or on behalf of the company seeking such tax deduction.

The amount of such deductible expenses is reduced by the sum of any funds received through government grants for the finance of such scientific research and development projects. No deduction under these research and development deduction rules is allowed if such deduction is related to an expense invested in an asset depreciable under the general depreciation rules of the income Tax Ordinance, 1961. Expenditures not so approved are deductible in equal amounts over three years.

From time to time we may apply the Office of the Chief Scientist for approval to allow a tax deduction for all research and development expenses during the year incurred. There can be no assurance that such application will be accepted.

Law for the Encouragement of Industry (Taxes), 1969

The Law for the Encouragement of Industry (Taxes), 1969, generally referred to as the Industry Encouragement Law, provides several tax benefits for industrial companies. We believe that we currently qualify as an “Industrial Company” within the meaning of the Industry Encouragement Law. The Industry Encouragement Law defines “Industrial Company” as a company resident in Israel, of which 90% or more of its income in any tax year, other than of income from defense loans, capital gains, interest and dividend, 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.

The following corporate tax benefits, among others, are available to Industrial Companies:

Amortization of the cost of purchased know-how and patents and of rights to use a patent and know-how which are used for the development or advancement of the company, over an eight-year period;

Accelerated depreciation rates on equipment and buildings;

Under specified conditions, an election to file consolidated tax returns with additional related Israeli Industrial Companies; and

Expenses related to a public offering in Israel and in recognized stock markets outside Israel, are deductible in equal amounts over three years.

Under certain tax laws and regulations, an “Industrial Enterprise” may be eligible for special depreciation rates for machinery, equipment and buildings. These rates differ based on various factors, including the date the operations begin and the number of work shifts. An “Industrial Company” owning an approved enterprise may choose between these special depreciation rates and the depreciation rates available to the approved enterprise.

Eligibility for the benefits under the Industry Encouragement Law is not subject to receipt of prior approval from any governmental authority. We can give no assurance that we qualify or will continue to qualify as an “Industrial Company” or that the benefits described above will be available in the future.

Special Provisions Relating to Taxation Under Inflationary Conditions

The Income Tax Law (Inflationary Adjustments), 1985, generally referred to as the Inflationary Adjustments Law, represents an attempt to overcome the problems presented to a traditional tax system by an economy undergoing rapid inflation.

According to the Inflationary Adjustments Law, until 2007, the results for tax purposes were adjusted for the changes in the Israeli CPI. In February 2008, the “Knesset,” the Israeli parliament, passed an amendment to the Inflationary Adjustments Law, which limits the scope of the law starting 2008 and thereafter. Starting 2008, the results for tax purposes are measured in nominal values, excluding certain adjustments for changes in the Israeli CPI carried out in the period up to December 31, 2007. The amendment to the Inflationary Adjustments Law includes, inter alia, the elimination of the inflationary additions and deductions and the additional deduction for depreciation starting 2008.

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

Tax benefits prior the 2005 amendment

The Law for the Encouragement of Capital Investments, 1959, as amended (effective as of April 1, 2005), generally referred to as the Investments Law, provides that a proposed capital investment in eligible facilities may, upon application to the Investment Center of the Ministry of Industry and Commerce of the State of Israel, be designated as an “Approved Enterprise.” The Investment Center bases its decision as to whether or not to approve an application, among other things, on the criteria set forth in the Investments Law and regulations, the policy of the Investment Center, and the specific objectives and financial criteria of the applicant. Each certificate of approval for an Approved Enterprise relates to a specific investment program delineated both by its financial scope, in cluding its capital sources, and by its physical characteristics, such as the equipment to be purchased and utilized pursuant to the program.

The Investments Law provides that an approved enterprise is eligible for tax benefits on taxable income derived from its approved enterprise programs. The tax benefits under the Investments Law also apply to income generated by a company from the grant of a usage right with respect to know-how developed by the Approved Enterprise, income generated from royalties, and income derived from a service which is auxiliary to such usage right or royalties, provided that such income is generated within the Approved Enterprise’s ordinary course of business. If a company has more than one approval or only a portion of its capital investments are approved, its effective tax rate is the result of a weighted average of the applicable rates. The tax benefits under the Investments Law are not, generally, available with respect to income derived from products ma nufactured outside of Israel. In addition, the tax benefits available to an Approved Enterprise are contingent upon the fulfillment of conditions stipulated in the Investments Law and regulations and the criteria set forth in the specific certificate of approval, as described above. In the event that a company does not meet these conditions, it would be required to refund the amount of tax benefits, plus a consumer price index linkage adjustment and interest.

The Investments Law also provides that an Approved Enterprise is entitled to accelerated depreciation on its property and equipment that are included in an Approved Enterprise program in the first five years of using the equipment.

Taxable income of a company derived from an Approved Enterprise is subject to corporate tax at the maximum rate of 25%, rather than the regular corporate tax rate, for the benefit period. This period is ordinarily seven years commencing with the year in which the approved enterprise first generates taxable income after the commencement of production, and is limited to twelve years from commencement of production or fourteen years from the date of approval, whichever is earlier. This time limitation does not apply to the exemption period described below.

Should we derive income from sources other than the Approved Enterprise during the relevant period of benefits, such income will be taxable at the regular corporate tax rates.

Under certain circumstances (as further detailed below), the benefit period may extend to a maximum of ten years from the commencement of the benefit period.

A company may elect to receive an alternative package of benefits. Under the alternative package of benefits, a company’s undistributed income derived from the Approved Enterprise will be exempt from corporate tax for a period of between two and ten years from the first year the company derives taxable income under the program, after the commencement of production, depending on the geographic location of the Approved Enterprise within Israel, and such company will be eligible for a reduced tax rate for the remainder of the benefits period. The year’s limitation does not apply to the exemption period.

A company that has elected the alternative package of benefits, such as us, that subsequently pays a dividend out of income derived from the approved enterprise(s) during the tax exemption period will be subject to corporate tax in the year the dividend is distributed in respect of the gross amount distributed, at the rate which would have been applicable had the company not elected the alternative package of benefits, (generally 10%-25%, depending on the percentage of the company’s ordinary shares held by foreign shareholders). The dividend recipient is subject to withholding tax at the reduced rate of 15% applicable to dividends from approved enterprises, if the dividend is distributed during the tax exemption period or within twelve years thereafter. In the event, however, that the company is qualifies as a foreign investors’ company, there is no such time limitation. This tax must be withheld by the company at source, regardless of whether the dividend is converted into foreign currency.

As of December 31, 2009, we believe that we are meeting the aforementioned conditions.

Foreign Investor’s Company (“FIC”)

A company that has an Approved Enterprise program is eligible for further tax benefits if it qualifies as a foreign investors’ company. A foreign investors’ company is a company of which, among other criteria, more than 25% of its share capital and combined share and loan capital is owned by non-Israeli residents. A company that qualifies as a foreign investors’ company and has an approved enterprise program is eligible for tax benefits for a ten-year benefit period. As specified above, depending on the geographic location of the approved enterprise within Israel, income derived from the approved enterprise program may be entitled to the following:

Extension of the benefit period to up to ten years.

An additional period of reduced corporate tax liability at rates ranging between 10% and 25%, depending on the level of foreign (that is, non-Israeli) ownership of our shares. Those tax rates and the related levels of foreign investment are as set forth in the following table:

Region A

Rate of Reduced Tax	Reduced Tax Period	Tax Exemption Period	Percent of Foreign Ownership
25	0 years	10 years	0-25%
25	0 years	10 years	25-48.99%
20	0 years	10 years	49-73.99%
15	0 years	10 years	74-89.99%
10	0 years	10 years	90-100%

Region B

Rate of Reduced Tax	Reduced Tax Period	Tax Exemption Period	Percent of Foreign Ownership
25	1 years	6 years	0-25%
25	4 years	6 years	25-48.99%
20	4 years	6 years	49-73.99%
15	4 years	6 years	74-89.99%
10	4 years	6 years	90-100%

Other Regions

Rate of Reduced Tax	Reduced Tax Period	Tax Exemption Period	Percent of Foreign Ownership
25	5 years	2 years	0-25%
25	8 years	2 years	25-48.99%
20	8 years	2 years	49-73.99%
15	8 years	2 years	74-89.99%
10	8 years	2 years	90-100%

The twelve years limitation period for reduced tax rate of 15% on dividend from the approved enterprise will not apply.

Subject to applicable provisions concerning income under the alternative package of benefits, dividends paid by a company are considered to be attributable to income received from the entire company and the company’s effective tax rate is the result of a weighted average of the various applicable tax rates, excluding any tax-exempt income. Under the Investments Law, a company that has elected the alternative package of benefits is not obliged to distribute retained profits, and may generally decide from which year’s profits to declare dividends.

We currently intend to reinvest any income derived from our Approved Enterprise program and not to distribute such income as a dividend. As of December 31, 2009, we did not generate income under the provisions of the Investments Law.

Tax Benefits under the 2005 Amendment

A recent amendment to the Investments Law, generally referred as the 2005 Amendment, effective as of April 1, 2005 has significantly changed the provisions of the Investments Law. The amendment includes revisions to the criteria for investments qualified to receive tax benefits as an Approved Enterprise. The 2005 Amendment applies to new investment programs and investment programs commencing after 2004, and does not apply to investment programs approved prior to December 31, 2004, and therefore to benefits included in any certificate of approval that was granted before the 2005 Amendment came into effect, which will remain subject to the provisions of the Investments Law as they were on the date of such approval.

However, a company that was granted benefits according to Section 51 of the Investments Law (prior the 2005 Amendment) will not be allowed to choose new tax year as a “Year of Election,” referred to below, under the 2005 Amendment, for a period of two years from the company’s previous Commencement Year (referred to below) under the old Investments Law.

The 2005 Amendment simplifies the approval process for the approved enterprise. According to the 2005 Amendment, only approved enterprises receiving cash grants require the approval of the Investment Center. The Investment Center will be entitled to approve such programs only until December 31, 2007.

As a result of the 2005 Amendment, it is no longer necessary for a company to acquire Approved Enterprise status in order to receive the tax benefits previously available under the Alternative Route, and therefore such companies need not apply to the Investment Center for this purpose. Rather, a company may claim the tax benefits offered by the Investments Law directly in its tax returns or by notifying the Israeli Tax Authority within twelve months of the end of that year, provided that its facilities meet the criteria for tax benefits set out by the 2005 Amendment. Such enterprise is referred to as the Benefited Enterprise. Companies are also granted a right to approach the Israeli Tax Authority for a pre-ruling regarding their eligibility for benefits under the 2005 Amendm ent. The 2005 Amendment includes provisions attempting to ensure that a company will not enjoy both Government grants and tax benefits for the same investment program.

Tax benefits are available under the 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 2005 Amendment states that a company must make an investment in the Benefited Enterprise exceeding a certain percentage or a minimum amount specified in the Investments 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 Benefited Enterprise, or 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 Benefited Enterprise and the company’s effective tax rate will be the result of a weighted average of the applicable rates. In this case, the minimum investment required in order to qualify as a Benefited 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 duration of tax benefits is subject to a limitation of the earlier of seven to ten years from the Commencement Year, or twelve years from the first day of the Year of Election. The Commencement Year is defined as the later of (a) the first tax year in which a company had derived income for tax purposes from the Beneficiary Enterprise or (b) the year in which a company requested to have the tax benefits apply to the Beneficiary Enterprise – Year of Election. The tax benefits granted to a Benefited Enterprise are determined, as applicable to its geographic location within Israel, according to one of the following new tax routes, which may be applicable to us:

Similar to the currently available alternative route, exemption from corporate tax on undistributed income for a period of two to ten years, depending on the geographic location of the Benefited Enterprise within Israel, and a reduced corporate tax rate of 10% to 25% for the remainder of the benefits period, depending on the level of foreign investment in each year. Benefits may be granted for a term of seven to ten years, depending on the level of foreign investment in the company. If the company pays a dividend out of income derived from the Benefited Enterprise during the tax exemption period, such income will be subject to corporate tax at the applicable rate (10%-25%) in respect of the gross amount of the dividend that we may be distributed. The company is required to withhold tax at the source at a rate of 15% from any dividends distributed from income derived from the Benefited Enterprise; and

A special tax route, which enables companies owning facilities in certain geographical locations in Israel to pay corporate tax at the rate of 11.5% on income of the Benefited Enterprise. The benefits period is ten years. Upon payment of dividends, the company is required to withhold tax at source at a rate of 15% for Israeli residents and at a rate of 4% for foreign residents.

Generally, a company that is Abundant in Foreign Investment (owned by at least 74% foreign shareholders and has undertaken to invest a minimum sum of $20 million in the Beneficiary Enterprise as defined in the Investments Law) is entitled to an extension of the benefits period by an additional five years, depending on the rate of its income that is derived in foreign currency.

The 2005 Amendment changes the definition of “foreign investment” in the Investments Law so that the definition now requires a minimal investment of NIS 5 million by foreign investors. Furthermore, such definition now also includes the purchase of shares of a company from another shareholder, provided that the company’s outstanding and paid-up share capital exceeds NIS 5 million. Such changes to the aforementioned definition will take effect retroactively from 2003.

The 2005 Amendment will apply to approved enterprise programs in which the year of election under the Investments Law is 2004 or later, unless such programs received approval from the Investment Center on or prior to December 31, 2004, in which case the 2005 Amendment provides that terms and benefits included in any certificate of approval already granted will remain subject to the provisions of the law as they were on the date of such approval.

As a result of the 2005 Amendment, tax-exempt income generated under the provisions of the Investments Law, as amended, will subject us to taxes upon distribution or liquidation and we may be required to record deferred tax liability with respect to such tax-exempt income.

We elected 2007 as "year of election" under the Investments Law after the Amendment.

We expect that a substantial portion of any taxable operating income that we may realize in the future will be derived from our approved enterprise status.

Capital Gains Tax 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, unless a specific exemption is available or unless a tax treaty between Israel and the shareholder’s country of residence provides otherwise. The law 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, in certain circumstances, a foreign currency exchange rate, between the date of purchase and the date of sale. The real gain is the excess of the tota l capital gain over the inflationary surplus.

As of January 1, 2006, the tax rate applicable to capital gains derived from the sale of shares, whether or not listed on a stock market, 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 “material shareholder” at any time during the twelve-month period preceding such sale, that is, such shareholder holds directly or indirectly, including with others, at least 10% of any means of control in the company, the tax rate shall be 25%. Israeli companies are subject to the corporate tax rate on capital gains derived from the sale of shares, unless such companies were not subject to the Inflationary Adjustments Law (or certain regulations) at the time of p ublication of the aforementioned amendment to the Tax Ordinance that came into effect on January 1, 2006, in which case the applicable tax rate is 25%. However, the foregoing tax rates do not apply to: (i) dealers in securities; and (ii) shareholders who acquired their shares prior to an initial public offering (that may be subject to a different tax arrangement).

The tax basis of shares acquired prior to January 1, 2003 will 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.

Non-Israeli residents are exempt from Israeli capital gains tax on any gains derived from the sale of shares of Israeli companies publicly traded on a recognized stock exchange or regulated market outside of Israel, provided, however, that such capital gains are not derived from a permanent establishment in Israel, such shareholders are not subject to the Inflationary Adjustments Law, and such shareholders did not acquire their shares prior to an initial public offering. However, non-Israeli corporations will not be entitled to such exemption if an Israeli resident (i) has a controlling interest of 25% or more in such non-Israeli corporation, or (ii) is the beneficiary or is entitled to 25% or more of the revenues or profits of such non-Israeli corporation, whether directly or indirectly.

In some instances where our shareholders may be liable to Israeli tax on the sale of their ordinary shares, the payment of the consideration may be subject to the withholding of Israeli tax at the source.

Pursuant to the Convention Between the government of the United States of America and the government of Israel with Respect to Taxes on Income, as amended, generally referred to as the U.S.-Israel Tax Treaty, the sale, exchange or disposition of ordinary shares by a person who (i) holds the ordinary shares as a capital asset, (ii) qualifies as a resident of the United States within the meaning of the U.S.-Israel Tax Treaty and (iii) is entitled to claim the benefits afforded to such person by the U.S.-Israel Tax Treaty, generally, will not be subject to the Israeli capital gains tax. Such exemption will not apply if (a) such Treaty U.S. Resident holds, directly or indirectly, shares representing 10% or more of our voting power during any part of the twelve-month period preceding such sale, exchange or disposition, subject to certain conditions, or (b) the capital gains from such sale, exchange or disposition can be allocated to a permanent establishment in Israel. In such case, the sale, exchange or disposition of ordinary shares would be subject to Israeli tax, to the extent applicable; however, under the U.S.-Israel Tax Treaty, such Treaty U.S. Resident would be permitted to claim a credit for such taxes against the U.S. federal income tax imposed with respect to such sale, exchange or disposition, subject to the limitations in U.S. laws applicable to foreign tax credits. The U.S.-Israel Tax Treaty does not relate to U.S. state or local taxes.

Taxation of Non-Resident Holders of Shares

Non-residents of Israel are subject to income tax on income accrued or derived from sources in Israel. Such sources of income include passive income such as dividends, royalties and interest, as well as non-passive income from services rendered in Israel. As of 2006, distributions of dividends other than bonus shares, or stock dividends, income tax is withheld at the source at the rate of 20%, 15% for dividends generated by an approved enterprise (if the dividend is distributed during the tax exemption period or within 12 years thereafter). In the event, however, that the company qualifies as a Foreign Investors’ Company, there is no such time limitation, unless a different rate is provided in a treaty between Israel and the shareholder’s country of residence.

Under the U.S.-Israel Tax Treaty, the maximum tax on dividends paid to a holder of ordinary shares who is a Treaty U.S. Resident is 20%. However, under the Investments Law, dividends generated by an Approved Enterprise (or Benefited Enterprise) are taxed at the rate of 15%. Furthermore, dividends not generated by an Approved Enterprise (or Benefited Enterprise) paid to a U.S. corporation holding at least 10% of our issued voting power during the part of the tax year which precedes the date of payment of the dividend and during the whole of its prior tax year, are generally taxed at a rate of 12.5%.

United States Federal Income Taxation

The following is a description of the material United States federal income tax consequences of the ownership and disposition of our ordinary shares. This description addresses only the United States federal income tax considerations of holders that are initial purchasers of our ordinary shares pursuant to the offering and that will hold such ordinary shares as capital assets. This description does not address tax considerations applicable to holders that may be subject to special tax rules, including:

financial institutions or insurance companies;

real estate investment trusts, regulated investment companies or grantor trusts;

dealers or traders in securities or currencies;

tax-exempt entities;

certain former citizens or long-term residents of the United States;

persons that will hold our shares through a partnership or other pass-through entity;

persons that received our shares as compensation for the performance of services;

persons that will hold our shares as part of a “hedging” or “conversion” transaction or as a position in a “straddle” for United States federal income tax purposes;

persons whose “functional currency” is not the United States dollar; or

holders that own directly, indirectly or through attribution 10.0% or more of the voting power or value of our shares.

Moreover, this description does not address the United States federal estate and gift or alternative minimum tax consequences of the acquisition, ownership and disposition of our ordinary shares.

This description is based on the U.S. Internal Revenue Code of 1986, as amended, existing, proposed and temporary United States Treasury Regulations and judicial and administrative interpretations thereof, in each case as in effect and available on the date hereof. All of the foregoing are subject to change, which change could apply retroactively and could affect the tax consequences described below.

For purposes of this description, a “U.S. Holder” is a beneficial owner of our ordinary shares that, for United States federal income tax purposes, is:

a citizen or resident of the United States;

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

an estate the income of which is subject to United States federal income taxation regardless of its source; or

a trust if such trust has validly elected to be treated as a United States person for United States federal income tax purposes or if (1) a court within the United States is able to exercise primary supervision over its administration and (2) one or more United States persons have the authority to control all of the substantial decisions of such trust.

A “Non-U.S. Holder” is a beneficial owner of our ordinary shares that is neither a U.S. Holder nor a partnership (or other entity treated as a partnership for United States federal income tax purposes).

If a partnership (or any other entity treated as a partnership for United States federal income tax purposes) holds our ordinary shares, the tax treatment of a partner in such partnership will generally depend on the status of the partner and the activities of the partnership. Such a partner or partnership should consult its tax advisor as to its tax consequences.

You should consult your tax advisor with respect to the United States federal, state, local and foreign tax consequences of acquiring, owning and disposing of our ordinary shares.

Distributions

Subject to the discussion below under “Passive Foreign Investment Company Considerations,” if you are a U.S. Holder, for United States federal income tax purposes, the gross amount of any distribution made to you, with respect to your ordinary shares before reduction for any Israeli taxes withheld therefrom, other than certain distributions, if any, of our ordinary shares distribute pro rata to all our shareholders, will be includible in your income as dividend income to the extent such distribution is paid out of our current or accumulated earnings and profits as determined under United States federal income tax principles. Subject to the discussion below under “Passive Foreign Investment Company Considerations,” non-corporate U.S. Holders may qualify for the lower rate s of taxation with respect to dividends on ordinary shares applicable to long-term capital gains (that is, gains from the sale of capital assets held for more than one year) with respect to taxable years beginning on or before December 31, 2010, provided that certain conditions are met, including certain holding period requirements and the absence of certain risk reduction transactions. However, such dividends will not be eligible for the dividends received deduction generally allowed to corporate U.S. Holders. Subject to the discussion below under “Passive Foreign Investment Company Considerations,” to the extent, if any, that the amount of any distribution by us exceeds our current and accumulated earnings and profits as determined under United States federal income tax principles, it will be treated first as a tax-free return of your adjusted tax basis in your ordinary shares and thereafter as capital gain. We do not expect to maintain calculations of our earnings and profits under U nited States federal income tax principles and, therefore, if you are a U.S. Holder you should expect that the entire amount of any distribution generally will be reported as dividend income to you.

If you are a U.S. Holder, dividends paid to you with respect to your ordinary shares will be treated as foreign source income, which may be relevant in calculating your foreign tax credit limitation. Subject to certain conditions and limitations, Israeli tax withheld on dividends may be deducted from your taxable income or credited against your United States 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, dividends that we distribute generally should constitute “passive category income,” or, in the case of certain U.S. Holders, “general category income.” A foreign tax credit for foreign taxes imposed on distributions may be denied when you do not satisfy certain minimum holding period requirements. The rules relating to the determination of the foreign tax credit are complex, and you should consult your personal tax advisors to determine whether and to what extent you would be entitled to this credit.

Subject to the discussion below under “Backup Withholding Tax and Information Reporting Requirements,” if you are a Non-U.S. Holder, you generally will not be subject to United States federal income or withholding tax on dividends received by you on your ordinary shares, unless you conduct a trade or business in the United States and such income is effectively connected with that trade or business.

Sales Exchange or other Disposition of Ordinary Shares

Subject to the discussion below under “Passive Foreign Investment Company Considerations,” if you are a U.S. Holder, you generally will recognize gain or loss on the sale, exchange or other disposition of your ordinary shares equal to the difference between the amount realized on such sale, exchange or other disposition and your adjusted tax basis in your ordinary shares. Such gain or loss will be capital gain or loss. If you are a non corporate U.S. Holder, capital gain from the sale, exchange or other disposition of ordinary shares is eligible for the preferential rate of taxation applicable to long-term capital gains, with respect to taxable years beginning on or before December 31, 2010, if your holding period for such ordinary shares exceeds one year (that is, such gain is long-term capital gain). Gain or loss, if any, recognized by you generally will be treated as United States source income or loss for United States foreign tax credit purposes. The deductibility of capital losses for U.S. federal income tax purposes is subject to limitations.

Subject to the discussion below under “Backup Withholding Tax and Information Reporting Requirements,” if you are a Non-U.S. Holder, you generally will not be subject to United States federal income or withholding tax on any gain realized on the sale or exchange of such ordinary shares unless:

such gain is effectively connected with your conduct of a trade or business in the United States; or

you are an individual and have been present in the United States for 183 days or more in the taxable year of such sale or exchange and certain other conditions are met.

Passive Foreign Investment Company Considerations

A non-U.S. corporation will be classified as a “passive foreign investment company,” or a PFIC, for United States federal income tax purposes in any taxable year in which, after applying certain look-through rules, either:

at least 75 percent of its gross income is "passive income"; or

at least 50 percent of the average value of its gross assets (based on the quarterly value of such gross assets) is attributable to assets that produce “passive income” or are held for the production of passive income.

Passive income for this purpose generally includes dividends, interest, royalties, rents, gains from commodities and securities transactions, the excess of gains over losses from the disposition of assets which produce passive income, and includes amounts derived by reason of the temporary investment of funds raised in offerings of our ordinary shares.

PFIC status is an annual determination that is based on tests which are factual in nature and our status in future years will depend on our income, assets and activities in each of those years. Therefore there can be no assurance that we will not be considered a PFIC for any taxable year. While public companies often employ a market capitalization method to value their assets, the IRS has not issued guidance concerning how to value a foreign public company’s assets for PFIC purposes. The market price of our ordinary shares is likely to fluctuate and the market price of the shares of technology companies has been especially volatile. In certain circumstances, including volatile market conditions, it may be appropriate to employ alternative methods to more accurately determine the fair market value of ou r assets other than the market capitalization method. We obtained an opinion from a U.S. tax advisor providing the reasoning for adoption of an approach other than the market capitalization approach and applying the results of our valuation study that was conducted by an independent valuator. In view of certain estimates of our gross income and the average value of our gross assets, the latter supported by said third party valuation and opinion, we believe that we should not be classified as a PFIC for the taxable year ended December 31, 2009 . There can be no certainty, however, that the IRS will agree with our position. If we were a PFIC, and you are a U.S. Holder, you generally would be subject to ordinary income tax rates, imputed interest charges and other disadvantageous tax treatment (including the denial of the taxation of such dividends at the lower rates applicable to long-term capital gains, as discussed above under “—Distributions”) with respect to any gain from the s ale, exchange or other disposition of, and certain distributions with respect to, your ordinary shares. We are not providing any U.S. tax opinion to any U.S. Holder concerning our status as a PFIC for 2009, or any other tax year. A U.S. Holder should consult his, her or its own tax advisor with respect to the potential application of the PFIC rules in his, her or its particular circumstances.

Because the market price of our ordinary shares is likely to fluctuate and the market price of the shares of technology companies has been especially volatile, and because that market price may affect the determination of whether we will be considered a PFIC, we cannot assure you that we will not be considered a PFIC for any taxable year.

Under the PFIC rules, unless a U.S. Holder makes one of the elections described in the next paragraphs, a special tax regime will apply to both (a) any “excess distribution” by us (generally, the U.S. Holder’s ratable portion of distributions in any year which are greater than 125% of the average annual distribution received by such U.S. Holder in the shorter of the three preceding years or the U.S. Holder’s holding period) and (b) any gain realized on the sale or other disposition of the ordinary shares. Under this regime, any excess distribution and realized gain will be treated as ordinary income and will be subject to tax as if (a) the excess distribution or gain had been realized ratably over the U.S. Holder’s holding period, (b) the amount deemed realized had been subject to tax in each year of that holding period, and (c) the interest charge generally applicable to underpayments of tax had been imposed on the taxes deemed to have been payable in those years. In addition, dividend distributions made to you will not qualify for the lower rates of taxation applicable to long term capital gains discussed above under “Distributions.”

Certain elections are available to U.S. Holders of shares that may serve to alleviate some of the adverse tax consequences of PFIC status. If we agreed to provide the necessary information, you could avoid the interest charge imposed by the PFIC rules by making a qualified electing fund, or a QEF election, which election may be made retroactively under certain circumstances, in which case you generally would be required to include in income on a current basis your pro rata share of our ordinary earnings as ordinary income and your pro rata share of our net capital gains as long-term capital gain. We do not expect to provide to U.S. Holders the information needed to report income and gain pursuant to a QEF election, and we make no undertaking to provide such information in the event that we are a PFIC.

Under an alternative tax regime, you may also avoid certain adverse tax consequences relating to PFIC status discussed above by making a mark-to-market election with respect to your ordinary shares annually, provided that the shares are “marketable.” Shares will be marketable if they are regularly traded on certain U.S. stock exchanges (including NASDAQ) or on certain non-U.S. stock exchanges. For these purposes, the shares will generally be considered regularly traded during any calendar year during which they are traded, other than in negligible quantities, on at least fifteen days during each calendar quarter.

If you choose to make a mark-to-market election, you would recognize 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 shares and your adjusted tax basis in the PFIC shares. Losses would be allowed only to the extent of net mark-to-market gain previously included by you under the election for prior taxable years. If the mark-to-market election were made, then the PFIC rules set forth above relating to excess distributions and realized gains would not apply for periods covered by the election. If you make a mark-to-market election after the beginning of your holding period of our ordinary shares, you would be subject to interest charges with respect to the inclusion of ordinary income attributable to the period before the effective date of such election.< /font>

Under certain circumstances, ordinary shares owned by a Non-U.S. Holder may be attributed to a U.S. person owning an interest, directly or indirectly, in the Non-U.S. Holder. In this event, distributions and other transactions in respect of such ordinary shares may be treated as excess distributions with respect to such U.S. person, and a QEF election may be made by such U.S. person with respect to its indirect interest in us, subject to the discussion in the preceding paragraphs.

We may invest in stock of non-U.S. corporations that are PFICs. In such a case, provided that we are classified as a PFIC, a U.S. Holder would be treated as owning its pro rata share of the stock of the PFIC owned by us. Such a U.S. Holder would be subject to the rules generally applicable to shareholders of PFICs discussed above with respect to distributions received by us from such a PFIC and dispositions by us of the stock of such a PFIC (even though the U.S. Holder may not have received the proceeds of such distribution or disposition). Assuming we receive the necessary information from the PFIC in which we own stock, certain U.S. Holders may make the QEF election discussed above with respect to the stock of the PFIC owned by us, with the consequences discussed above. However, no assurance can be given that we will be able to provide U.S. Holders with such information.

If we were a PFIC, a holder of ordinary shares that is a U.S. Holder must file United States Internal Revenue Service Form 8621 for each tax year in which the U.S. Holder owns the ordinary shares.

Recently enacted legislation creates an additional annual filing requirement for U.S. persons who are shareholders of a PFIC. The legislation does not describe what information will be required to be included in the additional annual filing, but rather grants the Secretary of the U.S. Treasury authority to decide what information must be included in such annual filing. If our company were a PFIC for a given taxable year, then you should consult your tax advisor concerning your annual filing requirements.

You should consult your own tax advisor regarding our potential status as a PFIC and the tax consequences that would arise if we were treated as a PFIC.

Backup Withholding Tax and Information Reporting Requirements

United States backup withholding tax and information reporting requirements generally apply to certain payments to certain non-corporate holders of stock. Information reporting generally will apply to payments of dividends on, and to proceeds from the sale or redemption of, ordinary shares made within the United States, or by a United States payor or United States middleman, to a holder of ordinary shares, other than an exempt recipient (including a corporation, a payee that is not a United States person that provides an appropriate certification and certain other persons). A payor will be required to withhold backup withholding tax from any payments of dividends on, or the proceeds from the sale or redemption of, ordinary shares within the United States, or by a United States payor or United States midd leman, to a holder, other than an exempt recipient, if such holder fails to furnish its correct taxpayer identification number or otherwise fails to comply with, or establish an exemption from, such backup withholding tax requirements. The backup withholding tax rate currently is 28.0%.

Any amounts withheld under the backup withholding rules will be allowed as a refund or credit against the beneficial owner’s United States federal income tax liability, if any, provided that the required information is furnished to the IRS.

The above description is not intended to constitute a complete analysis of all tax consequences relating to acquisition, ownership and disposition of our ordinary shares. You should consult your tax advisor concerning the tax consequences of your particular situation.

In addition, we are not required under the Exchange Act to file periodic reports and financial statements with the Securities and Exchange Commission as frequently or as promptly as United States companies whose securities are registered under the Exchange Act.

I. Subsidiary Information

Not applicable.

ITEM 11: Quantitative and Qualitative Disclosures About Market Risk

Market risk is the risk of loss related to changes in market prices, including interest rates and foreign exchange rates, of financial instruments that may adversely impact our consolidated financial position, results of operations or cash flows.

Risk of Interest Rate Fluctuation

We do not have any long-term borrowings. We have a significant amount of cash that is currently invested primarily in interest bearing investment such as bank time deposits, money market funds, U.S. government treasury bills and ARS. These investments expose us to the changes in interest rates. If interest rates further decline, our results of operations may be adversely affected due to lower interest income from these investments. See “ITEM 3: Key Information—Risk Factors—We have invested a substantial portion of our cash in auction-rate securities, which subjects us to liquidity and investment risk. Due to uncertainties in the capital markets regarding auction-rate securities, we recorded impairment charges in 2007, 2008 and 2009, and, if the fair value of these investments were to decline further, we could be required to record further impairment charges related to these investments” and “—We may receive much lower interest income on our interest bearing investments and suffer from losses due to the macro economic situation that may cause interest rates to remain at their current low level or further decline” and “ITEM 5: Operating and Financial Review and Prospects—Operating Results—Overview—Financial income (expenses), net” for further information regarding our investments in auction rate securities. The primary objective of our investment activities is to preserve principal while maximizing the income that we receive from our investments without significantly increasing risk and loss. Our investments are exposed to market risk due to fluctuation in interest rates, which may affect our interest income and the fair market value of our investments. We manage this exposure by performing ongoing evaluations of our investments. Due to the short and medium-term maturities nature of our investments (other than ARS) to date, their carrying value approximates the fair value. We generally hold investments to maturity in order to limit our exposure to interest rate fluctuations.

Foreign Currency Exchange Risk

Our foreign currency exposures give rise to market risk associated with exchange rate movements of the U.S. dollar, our functional and reporting currency, mainly against the shekel. In 2009, we derived our revenues primarily in U.S. dollars and a portion in euors and other currencies. Although a substantial part of our expenses were denominated in U.S. dollars, a significant portion of our expenses were denominated in shekels and to a lesser extent in euros and other Asian currencies. Our shekel-denominated expenses consist principally of salaries and related personnel expenses. We monitor foreign currency exposure and, from time to time, may use various instruments to preserve the value of sales transactions and commitments; however, this cannot assure our protection against risks of currency fluctuations. For more information regard ing foreign currency related risks, please refer to “General Business Risks Relating to Our Business and Market.”

We use currency forward contracts together with currency options primarily to hedge payments in NIS. These transactions constitute a future cash flow hedge. As of December 31, 2009, we had outstanding forward contracts in the amount of $15 million. These transactions were for a period of up to twelve months. As of December 31, 2009, the fair value of the above mentioned foreign currency derivative contracts was $0.6 million.

None.

E. Use of Proceeds

The effective date of the registration statement (file no. 333-138313) for our initial public offering of ordinary shares, par value NIS 0.10, was November 15, 2006. The offering commenced on November 15, 2006 and terminated after the sale of all the securities registered. Lehman Brothers Inc. acted as the sole book-running manager for the offering, Deutsche Bank Securities Inc. acted as co-lead manager and, CIBC World Markets Corp. and RBC Capital Markets Corporation acted as co-managers. We registered 6,500,000 ordinary shares in the offering. We sold 6,500,000 ordinary shares at an aggregate offering price of $78 million at a price per share of $12.00. Under the terms of the offering, we incurred aggregate underwriting discounts of $5.5 million. We also incurred expenses of $2 million in connection wi th the offering. The net proceeds that we received as a result of the offering were $70.5 million.

From the effective date of the registration statement and until December 31, 2009, the net proceeds had been invested in cash equivalents, marketable securities, capital expenditure and other corporate purposes.

None of the net proceeds of the offering was paid directly or indirectly to any director, officer, general partner of ours or to their associates, persons owning ten percent or more of any class of our equity securities, or to any of our affiliates.

ITEM 15: Controls and Procedures

(a) Disclosure Controls and Procedures. Our management, including our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of December 31, 2009. Based on such evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that, as of December 31, 2009, our disclosures controls and procedures were effective at the reasonable assurance level.

(b) Management’s Annual Report on Internal Control Over Financial Reporting. Our management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act. Our internal control over financial reporting is a process 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. Our internal control over financial reporting includes those policies and procedures that:

pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets;

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 authorizations of our management and directors;

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 recognizes that there are inherent limitations in the effectiveness of any system of internal control over financial reporting, including the possibility of human error and the circumvention or override of internal control. Accordingly, even effective internal control over financial reporting can provide only reasonable assurance with respect to financial statement preparation, and may not prevent or detect all misstatements. Further, because of changes in conditions, the effectiveness of internal control over financial reporting may vary over time.

Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2009. In making this assessment, our management used the criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Our management has concluded, based on its assessment, that our internal control over financial reporting was effective as of December 31, 2009.

This annual report does not include an attestation report of the Company’s registered public accounting firm regarding internal control over financial reporting. Management’s report was not subject to attestation by the Company’s registered public accounting firm pursuant to the temporary rules of the Securities and Exchange Commission that permit the Company to provide only management’s report in this annual report. Our financial statements have been audited by Kost, Forer, Gabbay & Kasierer (a Member of Ernst & Young Global), an independent registered public accounting firm.

(c) Changes in Internal Control Over Financial Reporting. During the period covered by this report, no changes in our internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) have occurred that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

ITEM 16G. Corporate Governance

As a foreign private issuer, we are permitted under NASDAQ Marketplace Rule 5615(a)(3) to follow Israeli corporate governance practices instead of the NASDAQ Stock Market requirements, provided we disclose which requirements we are not following and the equivalent Israeli requirement. We must also provide NASDAQ with a letter from outside counsel in our home country, Israel, certifying that our corporate governance practices are not prohibited by Israeli law.

We rely on this “foreign private issuer exemption” with respect to the following items:

We follow the requirements of Israeli law with respect to the quorum requirement for meetings of our shareholders, which are different from the requirements of Rule 5620(c). Under our articles of association, the quorum required for an ordinary meeting of shareholders consists of at least two shareholders present in person, by proxy or by written ballot, who hold or represent between them at least 25% of the voting power of our shares, instead of 33 1/3% of the issued share capital provided by under the NASDAQ Global Market requirements. This quorum requirement is based on the default requirement set forth in the Israeli Companies Law, 1999, or the Companies Law. We submitted a letter from our outside counsel in connection with this item prior to our initial public offering in November 2006.

We do not seek shareholder approval for equity compensation plans in accordance with the requirements of the Companies Law, which does not fully reflect the requirements of Rule 5635(c). Under Israeli law, we may amend our 2006 Incentive Compensation Plan by the approval of our board of directors, and without shareholder approval as is generally required under Rule 5635(c). Under Israeli law, the adoption and amendment of equity compensation plans, including changes to the reserved shares, do not require shareholder approval. We submitted a letter from our outside counsel in connection with this item in June 2008.

We otherwise comply with the NASDAQ Stock Market rules requiring that listed companies have a majority of independent directors and maintain a compensation and nominating committee composed entirely of independent directors. We are also subject to Israeli corporate governance requirements applicable to companies incorporated in Israel whose securities are listed for trading on a stock exchange outside of Israel.

We may in the future provide NASDAQ with an additional letter or letters notifying NASDAQ that we are following our home country practices, consistent with the Israeli Companies Law and practices, in lieu of other requirements of Rule 5600.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of

ALLOT COMMUNICATIONS LTD.

We have audited the accompanying consolidated balance sheets of Allot Communications Ltd. ("the Company") as of December 31, 2009 and 2008, and the related consolidated statements of operations, shareholders' equity and cash flows for each of the three years in the period ended December 31, 2009. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements 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. We were not engaged to perform an audit of the Company's internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also incl udes 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 at December 31, 2009 and 2008, and the consolidated results of its operations and its cash flows for each of the three years in the period ended December 31, 2009, in conformity with U.S. generally accepted accounting principles.

As discussed in note 2(g) to the consolidated financial statements, effective April 1, 2009, the Company changed its method of accounting for recognition of other-than-temporary losses on debt securities.

NOTE 2:-

SIGNIFICANT ACCOUNTING POLICIES

The consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles ("U.S. GAAP").

a. Use of estimates:

The preparation of the consolidated financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates, judgments and assumptions. The Company's management believes that the estimates, judgments and assumptions used are reasonable based upon information available at the time they are made. These estimates, judgments and assumptions can affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the financial statements, and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.

b. Financial statements in U.S. dollars:

The majority of the revenues of the Company and its subsidiaries are generated in U.S. dollars ("dollar") or linked to the dollar. In addition, a major portion of the Company's and certain of its subsidiaries' costs are incurred or determined 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.

Accordingly, monetary accounts maintained in currencies other than the dollar are remeasured into U.S. dollars in accordance with Accounting Standards Codification No. 830 (formerly, FASB Statement No. 52), "Foreign Currency Matters" ("ASC No. 830"). All transactions gains and losses from the remeasurement of monetary balance sheet items are reflected in the statements of operations as financial income or expenses as appropriate.

c. Principles of consolidation:

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

d. Cash and cash equivalents:

The Company considers all unrestricted highly liquid investments which are readily convertible into cash, with maturity of three months or less at the date of acquisition, to be cash equivalents.

Restricted cash and deposits:

Restricted cash of $ 1,000 and restricted deposits of $ 60 are held in favor of financial institutions towards fulfillments of forward contract and operating obligations, respectively.

f. 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 New Israeli Shekels ("NIS") and bear interest at annual weighted average rate of 1.5% and 2.4% at December 31, 2009 and 2008, respectively. The short-term deposits are presented at cost, including accrued interest.

SIGNIFICANT ACCOUNTING POLICIES (Cont.)

g. Marketable securities:

The Company accounts for its investments in marketable securities using Accounting Standards Codification No. 320 (formerly, FASB Statement No. 115), "Investments – Debt and Equity Securities" ("ASC No. 320").

The Company's management determines the appropriate classification of marketable securities at the time of purchase and evaluates such designation as of each balance sheet date. The Company classifies all of its marketable securities as available for sale. Available for sale securities are carried at fair value, with the unrealized gains and losses, reported in "accumulated other comprehensive income (loss)" in shareholders' equity. Realized gains and losses on sale of investments are included in earnings and are derived using the specific identification method for determining the cost of securities. The amortized cost of debt securities is adjusted for amortization of premiums and accretion of discounts to maturity. Such amortization together with interest and dividends on securities are included in financial income, net, if any. As of December 31, 2 009, the Company held marketable securities in U.S. dollars in the United States. The balance was composed of Auction Rate Securities ("ARS").

Until 2009, the Company recognized an impairment charge when a decline in the fair value of its investments below the cost basis is judged to be other-than-temporary. The entire difference between amortized cost and fair value is recognized in earnings. Factors considered in making such a determination include the duration and severity of the impairment, the reason for the decline in value and the potential recovery period.

In April 2009, the Company adopted the FASB's updated guidance relating to investments and debt securities, which amends the other-than-temporary impairment ("OTTI") guidance in U.S. GAAP. Under the updated guidance, if OTTI occurs, and it is more likely than not that the Company will not sell the investment or debt security before the recovery of its amortized cost basis, then the OTTI is separated into (a) the amount representing the credit loss and (b) the amount related to all other factors. The amount of the total OTTI related to credit loss is recognized in earnings. The amount of the total OTTI related to other factors is recognized in accumulated other comprehensive income. As a result of the adoption of this update accounting guidance, the Company recorded a cumulative effect adjustment of $7,681 to reclassify the non-credit compone nt of previously recognized impairments from accumulated deficit to accumulated other comprehensive income (loss), as further detailed in Note 4.

h. Inventories:

Inventories are stated at the lower of cost or market value. Inventory write-offs are provided to cover risks arising from slow-moving items or technological obsolescence for which recoverability is not probable. Inventory write-offs due to slow moving items and technological obsolescence totaled $ 815, $ 234 and $ 175 in 2009, 2008 and 2007, respectively.

Cost is determined as follows:

Raw materials - using the "first in, first out" (FIFO) cost method.

Finished goods - on the basis of raw materials, manufacturing cost and allocable indirect cost.

j. Goodwill and intangible assets:

Goodwill represents the excess of the purchase price over the fair value of net assets of purchased businesses is recorded as goodwill. Under Accounting Standards Codification No. 350 (formerly, FASB Statement No. 142), "Intangibles-Goodwill and Other" ("ASC No. 350"), goodwill and intangible assets deemed to have indefinite lives are tested for impairment annually, or more often if there are indicators to impairment present.

The Company performs annual impairment analysis of goodwill at December 31 of each year, or more often as applicable. The provisions of ASC No. 350 require that a two-step impairment test be performed on goodwill at the level of the reporting units. In the first step, the Company compares the fair value of each reporting unit to its carrying value. If the fair value exceeds the carrying value of the net assets, goodwill is considered not impaired, and no further testing is required to be performed. If the carrying value of the net assets exceeds the fair value, then the Company must perform the second step of the impairment test in order to determine the implied fair value of goodwill. If the carrying value of goodwill exceeds its implied fair value, then the Company would record an impairment loss equal to the difference.

The Company believes that its business activity and management structure meet the criterion of being a single reporting unit for accounting purposes. The Company has performed an annual impairment analysis as of December 31, 2009 and determined that the carrying value of the reporting unit was less than the fair value of the reporting unit. In calculating the fair value of the reporting unit, the market approach was the methodology used.

k. Impairment of long-lived assets:

Long-lived assets are reviewed for impairment in accordance with Accounting Standards Codification No. 360 (formerly, FASB Statement No. 144), "Property, Plant, and Equipment " ("ASC No. 360"), whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The recoverability of assets to be held and used is measured by a comparison of the carrying amount of the assets to the future undiscounted cash flows expected to be generated by the assets. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. As of December 31, 2009, 2008 and 2007, no impairment losses were recorded.

l. Revenue recognition:

The Company generates revenues mainly from the sale of hardware and software products along with related maintenance and support services. The Company generally sells its products through resellers, distributors, OEMs and system integrators, all of whom are considered end-customers from The Company's perspective.

The software components of the Company’s products are deemed to be more than incidental to the products as a whole, in accordance with Accounting Standards Codification No. 985-605 (formerly, Statement of Position SOP 97-2), "Revenue Recognition" ("ASC No. 985-605"). Therefore, The Company accounts for its product sales in accordance with ASC No. 985-605. Revenues from product sales are recognized when persuasive evidence of an agreement exists, delivery of the product has occurred, no significant performance obligations with regard to implementation remain, the fee is fixed or determinable and collectability is probable.

ASC No. 985-605 generally requires revenue earned on software arrangements involving multiple elements to be allocated to each element based on the relative objective fair value of the elements. Accordingly, revenues are 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 a customer, The Company defers revenue for the fair value of its undelivered elements (maintenance and support) and recognizes revenue for the remainder of the arrangement fee attributable to the elements initially delivered in the arrangement (hardware and software products) when all other criteria in ASC No. 985-605 have been met. Any discount in the arrangement is allocated to the delivered element.

Maintenance and support related revenues included in multiple element arrangements are deferred and recognized on a straight-line basis over the term of the applicable maintenance and support agreement. The VSOE of fair value of the maintenance and support services is determined based on the price charged when sold separately. Deferred revenues are classified as short and long terms and recognized as revenues at the time respective elements are provided.

The Company provides a provision for product returns and stock rotation based on its experience with historical sales returns, stock rotations and other known factors.

The Company grants a one-year hardware warranty and three-month software warranty on all of its products. The Company estimates the costs that may be incurred under its warranty arrangements 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.

m. Research and development costs:

Accounting Standards Codification No. 985 (formerly, FASB Statement No. 86), "Software" ("ASC No. 985"), 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 the completion of a working model. The Company does not incur material costs between the completion of a working model and the point at which the products are ready for general release. Therefore, research and development costs are charged to the consolidated statement of operations as incurred.

n. Severance pay:

The Company's liability for severance pay for its Israeli employees is calculated pursuant to Israel's Severance Pay Law, based on the most recent monthly salary of its employees multiplied by the number of years of employment as of the balance sheet date for such employees. The Company's liability is partly provided by monthly deposits with severance pay funds and insurance policies and the remainder by an accrual.

The deposited funds may be withdrawn only upon the fulfillment of the obligation pursuant to Israel's Severance Pay law, labor agreements and/or applicable case law. The value of the deposited funds and insurance policies is based on the cash surrendered value and includes profits accumulated up to the balance sheet date.

Severance expenses for the years ended December 31, 2009, 2008 and 2007, amounted to $ 961, $ 957 and $ 952, respectively.

o. Accounting for stock-based compensation:

The Company accounts for stock based compensation in accordance with Accounting Standards Codification No. 718 (formerly, FASB Statement No. 123R), "Compensation - Stock Compensation" ("ASC No. 718") that requires companies to estimate the fair value of equity-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 statement of operations.

The Company applies ASC No. 718 and Accounting Standards Codification No. 505-50 (formerly, EITF No. 96-18), "Equity-Based Payments to Non-Employees" ("ASC No. 505-50") with respect to options and warrants issued to non-employees. Accordingly, option valuation models to measure the fair value of the options and warrants at the measurement date as defined in ASC No. 505-50.

The Company recognizes compensation expenses for the value of its awards granted based on the straight-line method over the requisite service period of each of the awards, net of estimated forfeitures. ASC No. 718 requires forfeitures to be estimated at the time of the grant and revised in subsequent periods if actual forfeitures differ from those estimates.

The following table sets forth the total stock-based compensation expense resulting from stock options granted to employees and non-employees included in the consolidated statements of operations, for the years ended December 31, 2009, 2008 and 2007:

	Year ended December 31,

SIGNIFICANT ACCOUNTING POLICIES (Cont.)

The Company selected the binomial option pricing model as the most appropriate fair value method for its stock-based compensation awards (except for restricted-stack units, which are valued based on the market value of the underlying share at the date of grant) with the following weighted-average assumptions for the year ended December 31, 2009, 2008 and 2007:

	Year ended December 31,
	2009			2008			2007

Suboptimal exercise multiple		2.5-3.5			2 - 3.6			2-3
Interest rate		0.31%-5.19	%		1.07%-6.81	%		3.18%-5.38	%
Volatility		53%-60	%		62% - 75	%		75	%
Dividend yield		0	%		0	%		0	%
Weighted-average fair value at grant date		1.27			2.46			8.57

The computations of expected volatility and suboptimal exercise multiple are based on the average of the Company's realized historical stock price volatility and certain peer companies that the Company considered to be comparable based on market capitalization and type of technology platform. The computation of the suboptimal exercise multiple and the forfeiture rates are based on the employees expected exercise prior and post vesting termination behavior. The interest rate for period within the contractual life of the award is based on the U.S. Treasury Bills yield curve in effect at the time of grant. The Company currently has no plans to distribute dividends and intends to retain future earnings to finance the development of its business.

p. Concentration of credit risks:

Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents, restricted cash and deposits, marketable securities, short-term bank deposits, trade receivables and derivative instruments.

The majority of cash and cash equivalents, restricted cash and deposits, marketable securities and short-term deposits of the Company are invested in dollar deposits in major U.S. and Israeli banks. Such deposits in the United States may be in excess of insured limits and are not insured in other jurisdictions. Generally, the cash and cash equivalents and short-term bank deposits may be redeemed upon demand, and therefore, bear minimal risk.

The Company's trade receivables are primarily derived from sales to customers located mainly in the United States, Europe and Asia. Concentration of credit risk with respect to trade receivables is limited by credit limits, ongoing credit evaluation and account monitoring procedures. The Company performs ongoing credit evaluations of its customers and establishes an allowance for doubtful accounts on a specific basis. Allowance for doubtful accounts amounted to $ 253 and $ 180 as of December 31, 2009 and 2008, respectively.

The Company has no significant off balance sheet concentration of credit risk, except for hedging arrangements to cover the currency exposure of the NIS on identified cash flow items (see also Note 2v).

q. Royalty bearing grants:

Participation grants from the Office of the Chief Scientist of the Ministry of Industry, Trade and Labor in Israel ("OCS") for research and development activity are recognized at the time the Company is entitled to such grants on the basis of the costs incurred and included as a deduction of research and development costs. Research and development grants recognized amounted to $ 2,440, $ 2,671 and $ 2,371 in 2009, 2008 and 2007, respectively.

r. Income taxes:

The Company accounts for income taxes in accordance with Accounting Standards Codification No. 740 (formerly, FASB Statement No. 109), "Income Taxes" ("ASC No. 740"). ASC No. 740 prescribes the use of the liability method, whereby deferred tax asset and liability account balances are determined based on differences between financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. The Company provides a valuation allowance, if necessary, to reduce deferred tax assets to their estimated realizable value if it is more likely than not that some portion or all of the deferred tax assets will not be realized.

ASC No. 740 contains a two-step approach to recognizing and measuring a liability for uncertain tax positions. 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.

s. Basic and diluted net loss per share:

The Company accounts for earnings per share based on Accounting Standards Codification No. 260 (formerly, FASB Statement No. 128), "Earnings Per Share" ("ASC No. 260"). Basic earnings per share are calculated using the weighted average number of shares outstanding during the period. Diluted earnings per share is computed on the basis of the weighted average number of shares outstanding and the effect of dilutive potential shares of Ordinary shares considered outstanding during the period.

For the years ended December 31, 2009, 2008 and 2007, all outstanding options and warrants have been excluded from the calculation of the diluted loss per share since their effect was anti-dilutive.

t. Comprehensive income (loss):

The Company accounts for comprehensive income (loss) in accordance with Accounting Standards Codification No. 220 (formerly, FASB Statement No. 130), "Comprehensive Income"("ASC No. 220"). This statement 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 marketable securities.

u. Fair value of financial instruments:

The Company measures its cash and cash equivalents, marketable securities, derivative instruments, restricted cash and deposits, short-term bank deposits, trade receivables, other receivables, trade payables and other payables at fair value.

NOTE 2:-

SIGNIFICANT ACCOUNTING POLICIES (Cont.)

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 value hierarchy, which prioritizes the 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.

v. Derivatives and hedging:

The Company accounts for derivatives and hedging based on Accounting Standards Codification No. 815 (formerly, FASB Statement No. 133), "Derivatives and Hedging" ("ASC No. 815").

The Company accounts for its derivative instruments as either assets or liabilities and carries them at fair value. Derivative instruments that are not designated and qualified as hedging instruments must be adjusted to fair value through earnings.

For derivative instruments that hedge the exposure to variability in expected future cash flows that are designated as cash flow hedges, the effective portion of the gain or loss on the derivative instrument is reported as a component of accumulated other comprehensive income (loss) in shareholders' equity and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. The ineffective portion of the gain or loss on the derivative instrument is recognized in current earnings. To receive hedge accounting treatment, cash flow hedges must be highly effective in offsetting changes to expected future cash flows on hedged transactions.

w. Impact of recently issued accounting standards:

In April, 2009, the Company adopted the FASB's updated guidance Accounting Standards Codification No. 820-10 (formerly, FSP No. 157-04), related to fair value measurements and disclosures, which provides additional guidance for estimating fair value in accordance with the guidance related to fair value measurements when the volume and level of activity for an asset or liability have significantly decreased. The updated standard also includes guidance on identifying circumstances that indicate a transaction is not orderly. The Company adopted this standard effective April 1, 2009. The adoption of this guidance did not have a material effect on the consolidated financial statements.

In May 2009, the FASB issued Accounting Standards Codification No. 855 (formerly, FASB Statement No. 165), "Subsequent Events" ("ASC No. 855"). This standard is intended to establish general standards of accounting for and disclosures of events that occur after the balance sheet date but before financial statements are issued or are available to be issued. Specifically, this standard sets forth the period after the balance sheet date during which management of a reporting entity should evaluate events or transactions that may occur for potential recognition or disclosure in the financial statements, the circumstances under which an entity should recognize events or transactions occurring after the balance sheet date in its financial statements, and the disclosures that an entity should make about events or transactions that occurred after the balance sheet date. ASC No. 855 is effective for fiscal years and interim pe riods ended after June 15, 2009. The Company adopted this standard effective June 15, 2009. The adoption of this guidance did not have a material effect on the consolidated financial statements.

In June 2009, the Financial Accounting Standards Board ("FASB") issued a standard that established the FASB Accounting Standards Codification ("ASC") and amended the hierarchy of generally accepted accounting principles ("GAAP") such that the ASC became the single source of authoritative U.S. GAAP. Rules and interpretive releases issued by the SEC under authority of federal securities law are also sources of the authoritative GAAP for SEC registrants. All other literature is considered non-authoritative. New accounting standards issued subsequent to June 30, 2009 are communicated by the FASB through Accounting Standards Updates. The ASC is effective for the Company from September 1, 2009. Throughout the notes to the consolidated financial statements references that were previously made to former authoritative U.S. GAAP pronouncements have been changed to coincide with the appropriate section of the ASC.

In October 2009, the FASB issued an update to ASC No. 985-605, "Software-Revenue Recognition" (originally issued as EITF 09-3). In accordance with the update to the ASC, tangible products containing software components and non-software components that function together to deliver the tangible product's essential functionality are excluded from the scope of the software revenue recognition guidance. In addition, hardware components of a tangible product containing software component are always excluded from the software revenue guidance. The mandatory adoption is on January 1, 2011, with earlier adoption permitted. The Company may elect to adopt the update prospectively, to new or materially modified arrangements beginning on the adoption date, or retrospectively, for all periods presented. The Company is currently evaluating the impact on it s consolidated results of operations and financial condition, and has not yet determined the adoption date.

In October 2009, the FASB issued an update to ASC No. 605-25, "Revenue recognition – Multiple-Element Arrangements", that provides amendments to the criteria for separating consideration in multiple-deliverable arrangements to:

Provide updated guidance on whether multiple deliverables exist, how the deliverables in an arrangement should be separated, and how the consideration should be allocated;

Require an entity to allocate revenue in an arrangement using estimated selling prices ("ESP") of deliverables if a vendor does not have vendor-specific objective evidence of selling price ("VSOE") or third-party evidence of selling price ("TPE"); and

Eliminate the use of the residual method and require an entity to allocate revenue using the relative selling price method.

Require expanded disclosures of qualitative and quantitative information regarding application of the multiple-deliverable revenue arrangement guidance.

ACQUISITIONS

On January 8, 2008, the Company completed an acquisition of the business of Esphion Limited, ("Esphion") a New Zealand based, developer of network protection solutions for carriers and internet service providers. The total consideration including direct transaction costs for the acquisition was approximately $ 3,802, plus potential earn-outs based on performance milestones amounting to a maximum of an additional $ 2,000 payable through December 31, 2008.

As of December 31, 2008, Esphion met certain milestones in accordance with the acquisition agreement. Consequently, out of the maximum additional $ 2,000, the Company paid additional $ 186 and increased its goodwill accordingly.

The total purchase price of Esphion was composed of the following:

Cash paid	$	3,500
Acquisition related transaction costs		302

Total	$	3,802

Acquisition related transaction costs include investment banking fees, legal and accounting fees and other external costs directly related to the acquisition.

Purchase price allocation:

Under business combination accounting, the total purchase price was allocated to Esphion's net tangible and identifiable intangible assets based on their estimated fair values as set forth below. The excess of the purchase price over the net tangible and identifiable intangible assets was recorded as goodwill.

Tangible assets:
Current assets	$	61
Property and equipment		49

Net tangible assets		110

Intangible assets:
Core technology		726
In process research and development		244
Goodwill		2,722

ACQUISITIONS (Cont.)

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 revenues to be generated from the Service Protector. The fair value of the intangible assets was based on the Company's management estimates and assumptions that were utilized via a valuation of a third party valuation firm, using the income approach.

Core technology represents a combination of Esphion processes and patents related to the design and development of the Service Protector. This proprietary know-how can be leveraged to develop new technology and improve the Company's products (see also Note 8a).

The Company expensed in-process research and development ("IPR&D") in the amount of $ 244 upon acquisition as it represents incomplete Esphion research and development projects that had not reached technological feasibility and had no alternative future use as of the date of the acquisition. The value assigned to IPR&D was determined by considering the importance of the project to the Company's overall development plan, estimating costs to develop the purchased IPR&D into commercially viable products, estimating the resulting net cash flow from the project when completed and discounting the net cash flow to its present value based on the percentage of completion of the IPR&D projects.

Pro forma information in accordance with Accounting Standards Codification No. 805 (formerly, FASB Statement No. 141), "Business Combinations" ("ASC No. 805") has not been provided, since Esphion's results for 2008 and 2007, were not material in relation to total consolidated revenues and net loss.

(*)

ARS held by the Company are private placement securities with long-term nominal maturities for which the interest rates are reset through a "Dutch" auction each month. The monthly auctions historically have provided a liquid market for these securities. The Company's investments in ARS represent interests in collateralized debt obligations supported by pools of residential and commercial mortgages or credit cards, insurance securitizations and other structured credits. The ARS bear interest at rates ranging from 2.4% to 3.9% per annum.

The balance is comprised of ARS with contractual maturities of more than one year, which suffer from failed auctions since September 2007. As a result of the auction failures, these ARS do not have a readily determinable market value. In 2009, as there was insufficient observable market information available to determine the fair value of the ARS and the portion of the impairment that relates to credit loss of these securities, the fair value was determined using an independent third party valuator. The fair value was based on a trinomial discount model employing assumptions that market participants would use in their estimates of fair value.

NOTE 4:-

MARKETABLE SECURITIES (Cont.)

The assumptions included, among others, the following: the underlying structure of the security, the financial standing of the issuer, stated maturities, estimates of the probability of the issue being called at par prior to final maturity, estimates of the probability of defaults and recoveries, auctions failure and successful auction or repurchase at par for each period, expected changes in interest rates paid on the securities, interest rates paid on similar instruments. Finally, the present value of the future principal and interest payments was discounted at rates considered to reflect current market conditions for each security.

The Company had various factors in determining whether it should recognize an impairment charge prior to 2009 for its marketable securities, including its intent and ability to hold the investment for a period of time sufficient for any anticipated recovery in market value, the length of time and extent to which the fair value has been less than its cost basis, the credit ratings of the securities, the nature of underlying collateral, as applicable and the financial condition and near-term prospects of the issuer.

On April 1, 2009, the Company adopted ASC No. 320 that provides guidance on recognition and presentation of other-than-temporary impairments and assessed whether the unrealized losses for the investments in its portfolio were other-than-temporary under this guidance. For securities that the Company intends to sell or it is more likely than not that it will be required to sell the securities before recovery, the entire difference between amortized cost and fair value is recognized in earnings. For securities that the Company does not intend to sell and it is not more likely than not that the Company will be required to sell, the Company used a discounted cash flow analysis to determine the portion of the impairment that relates to credit loss.

Based on the Company's consideration of these factors, the Company recognized in 2009, 2008 and 2007 an other-than-temporary net impairment in a total amount of $ 3,036, $7,700 and $ 4,881, related to ARS, respectively. The Company may recognize additional losses in the future should the market prospects of the issuers of these securities continue to deteriorate. As of December 31, 2009 and 2008, interest receivable amounted to $ 25 and $ 27, respectively, and is included within other receivables in the balance sheets.

Since there is uncertainty about the Company's ability to liquidate the ARS in a short time, the entire amount of the ARS is presented as non-current assets on the Company's balance sheet.

During 2008, the Company redeemed at par value $ 12,352 and $ 7,243 ARS and corporate bonds, respectively. Following such redemption, the Company recorded capital gain of $ 5,346. The capital gain is presented in the Company's income statement net of other than temporary impairment.

To the extent that the net present value of the projected cash flows is less than the amortized cost of the security, the difference is considered a credit loss and is recorded through earnings. The inputs on the future performance of the underlying assets used in the cash flow models include prepayments, defaults and loss severity assumptions. The Company adopted ASC No. 320 in 2009, and reclassified the $ 7,681 non-credit related portion of other-than-temporary impairment losses recognized in prior period earnings as a cumulative effect adjustment that increased accumulated deficit and decreased accumulated other comprehensive income.

FAIR VALUE MEASUREMENTS

In accordance with ASC No. 820, the Company measures its cash equivalents, restricted cash and deposit, short-term bank deposits, marketable securities and foreign currency derivative instruments at fair value. Cash equivalents, restricted deposit and short-term bank deposits, except for investments in marketable securities are classified within Level 1 or Level 2. This is because these assets are valued using quoted market prices or alternative pricing sources and models utilizing market observable inputs. Investments in marketable securities are classified within Level 3 because they are valued using valuation techniques. Some of the inputs to these models are unobservable in the market and are significant.

The Company values the Level 3 investments based on an externally developed valuation 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.

The Company's financial assets measured at fair value on a recurring basis, excluding accrued interest components; consisted of the following types of instruments as of December 31, 2009 and 2008, respectively:

COMMITMENTS AND CONTINGENT LIABILITIES (Cont.)

Lawsuit:

On May 1, 2007, a securities class action complaint, Brickman Investment Inc. v. Allot Communications Ltd. et al., was filed in the United States District Court for the Southern District of New York. At least three substantially similar complaints were filed in the same court after the original action was filed. We and certain of our directors and officers are named as defendants. The securities class action complaints allege that the defendants violated Sections 11 and 15 of the Securities Act of 1933 by making false and misleading statements and omissions in our registration statement for our initial public offering in November 2006. The claims are purportedly brought on behalf of persons who purchased our s tock pursuant to and/or traceable to the initial public offering on or about November 15, 2006 through April 2, 2007. The plaintiffs seek unspecified compensatory damages against the defendants, as well as attorney’s fees and costs. Motions for consolidation and for appointment of lead plaintiff were filed on July 2, 2007 and were decided on March 27, 2008, with an order granting consolidation and appointing co-lead plaintiffs. The Consolidated Amended Compliant was served on June 9, 2008. The defendants moved to dismiss the Consolidated Amended Compliant on August 8, 2008. While the defendants’ motion to dismiss was still pending, the parties reached on March 31, 2010 an agreement in principle to settle this litigation. Pursuant to the terms of the agreement, the Company will pay to the plaintiffs, for the benefit of the class members, $1.3 million in cash, which amount is to be funded by the Company's insurance carrier. The settlement contemplated therein is conditional upon approval by the court and other contingencies. There is no assurance that final court approval will be obtained. If such approval is not obtained, the parties to this litigation may attempt to reach agreement on alternative settlement terms or resume the litigation. The Company has recorded a liability in its financial statements for the proposed amount of the settlement. In addition, because the insurance carrier has agreed to pay the entire settlement amount and recovery from the insurance carrier is probable, a receivable has also been recorded for the same amount. Accordingly, there is no impact to the Company’s statements of operations or cash flows because the amounts of the settlement and the insurance recovery fully offset each other (See Note 15).

Other:

The Company currently depends on two subcontractors to manufacture and provide hardware warranty support for its traffic management systems. If they experience delays, disruptions, quality control problems or a loss in capacity, shipments of products may be delayed and the Company’s ability to deliver products could be materially adversely affected. Certain hardware components for the Company’s products come from single or limited sources, and the Company could lose sales if these sources fail to satisfy its supply requirements. In the event that the Company terminates its business connection with the subcontractors, it will have to compensate the subcontractors for certain inventory costs, as specified in the agreement with the subcontractors.

SHAREHOLDERS' EQUITY (Cont.)

In October 2006, the Company's shareholders and the Board of Directors approved an addendum to the escrow agreement with the Founder regarding these shares. According to the addendum, if the right is not exercised prior to the consummation of a "Liquidity Event" as defined in the escrow agreement, or November 15, 2008, the right and the underlying shares will be forfeited. It was further approved that the Founder has the right to pay for any portion of the shares by "net payment". As a result of the modification of the right, the Company recorded a total expense of $ 150 in the year ended December 31, 2006. In November 2008, the Company's Audit Committee, Board of Directors and shareholders approved another addendum to the escrow agreement with the Founder pursuant to which the right to exercise these shares has been extended to the earlier of a "Liquidation Event" or November 15, 2010. For such transaction, the Company recorded compensation expense of $ 90 to operating expenses for the year ended in December 31, 2009.

TAXES ON INCOME

Income Tax (Inflationary Adjustments) Law, 1985:

According to the law, until 2007, the results for tax purposes were adjusted for the changes in the Israeli consumer price index ("Israeli CPI"). In February 2008, the "Knesset" (Israeli parliament) passed an amendment to the Income Tax (Inflationary Adjustments) Law, 1985, which limits the scope of the law starting 2008 and thereafter. Starting 2008, the results for tax purposes are measured in nominal values, excluding certain adjustments for changes in the Israeli CPI carried out in the period up to December 31, 2007. The amendment to the law includes, inter alia, the elimination of the inflationary additions and deductions and the additional deduction for depreciation starting 2008.

Corporate tax rates:

Tax benefits under Israel's law for the Encouragement of Capital Investments, 1959 ("the Law"):

In 1998, the production facilities of the Company related to its computational technologies were granted the status of an "Approved Enterprise" under the Law. In 2004, expansion program was granted the status of "Approved Enterprise". According to the provisions of the Law, the Company has elected the alternative package of benefits - and has waived Government grants in return for tax benefits.

According to the provisions of the Law, the Company's income is tax-exempt for a period of two years commencing with the year it first earns taxable income, and subject to corporate taxes at the reduced rate of 10% to 25%, for an additional period of five to eight years depending upon the level of foreign ownership of the Company. The benefit period of tax benefit has not yet commenced, since the Company has not yet reported taxable income.

NOTE 11:-

TAXES ON INCOME (Cont.)

The period of tax benefits, detailed above, is limited to the earlier of 12 years from the commencement of production, or 14 years from the approval date, (the year's limitation does not apply to the exemption period).

The Law was significantly amended effective April 1, 2005 ("the Amendment"). The Amendment includes revisions to the criteria for investments qualified to receive tax benefits as a Beneficiary Enterprise and among other things, simplifies the approval process. The Amendment applies to new investment programs. Therefore, investment programs commencing after December 31, 2004, do not affect the approved programs of the Company.

In addition, the Law provides that terms and benefits included in any letter of approval already granted will remain subject to the provisions of the Law as they were on the date of such approval. Therefore the Company's existing Approved Enterprise will generally not be subject to the provisions of the Amendment.

The entitlement to the above benefits is contingent upon the fulfillment of the conditions stipulated in the Law, regulations published there under and the criteria set forth in the specific letters of approval. In the event of failure to comply with these conditions, the benefits may be canceled and the Company may be required to refund the amount of the benefits, in whole or in part, including interest and linked to changes in the Israeli CPI. As of December 31, 2009, management believes that the Company is meeting the aforementioned conditions.

If the Company pays a dividend out of income derived from the Approved and Beneficiary Enterprise during the tax exemption period, it will be subject to corporate tax in respect of the gross amount distributed, including any taxes thereon, at the rate which would have been applicable had it not enjoyed the alternative benefits, generally 10%-25%, depending on the percentage of the Company's Ordinary shares held by foreign shareholders. The dividend recipient is subject to withholding tax at the rate of 15% applicable to dividends from approved enterprises, if the dividend is distributed during the tax exemption period or within twelve years thereafter. The Company currently has no plans to distribute dividends and intends to retain future earnings to finance the development of its business.

Income from sources other than the "Approved and Beneficiary Enterprise" during the benefit period will be subject to tax at the regular corporate tax rate.

Tax benefits under the law for the Encouragement of Industry (taxes), 1969 ("the Encouragement Law"):

The Encouragement Law, provides several tax benefits for industrial companies. An industrial company is defined as a company resident in Israel, at least 90% of the income of which in a given tax year exclusive of income from specified 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.

Management believes that the Company is currently qualified as an "industrial company" under the Encouragement Law and as such, enjoys tax benefits, including: (1) Deduction of purchase of know-how and patents and/or right to use a patent over an eight-year period; (2) The right to elect, under specified conditions, to file a consolidated tax return with additional related Israeli industrial companies and an industrial holding company; (3) Accelerated depreciation rates on equipment and buildings; and (4) Expenses related to a public offering on the Tel-Aviv Stock and on recognized stock markets outside of Israel, are deductible in equal amounts over three years.

DERIVATIVE INSTRUMENTS

The Company enters into hedge transactions with a major financial institution, using derivative instruments, primarily forward contracts and options to purchase and sell foreign currencies, in order to reduce the net currency exposure associated with anticipated expenses (primarily salaries and related expenses) in currencies other than U.S. dollar. The Company currently hedges such future exposures for a maximum period of one year. However, the Company may choose not to hedge certain foreign currency exchange exposures for a variety of reasons, including but not limited to immateriality, accounting considerations and the prohibitive economic cost of hedging particular exposures. There can be no assurance the hedges will offset more than a portion of the financial impact resulting from movements in foreign currency exchange rates.

The Company records all derivatives on the consolidated balance sheets at fair value. The effective portions of cash flow hedges are recorded in other comprehensive income until the hedged item is recognized in earnings. The ineffective portions of cash flow hedges are adjusted to fair value through earnings in financial other income or expense. The Company does not enter into derivative transactions for trading purposes.

The Company had a net deferred gain associated with cash flow hedges of $ 612 and $ 697 recorded in other comprehensive income as of December 31, 2009 and 2008, respectively. As of December 31, 2009, the hedged transactions are expected to occur within twelve months.

The Company entered into forward contracts to hedge the fair value of assets denominated in Euros that did not meet the requirement for hedge accounting. As of December 31, 2009 and 2008, the Company had outstanding forward contracts, for a period of up to twelve months, in the amount of $ 1,138 and $ 0, respectively. The Company measured the fair value of the contracts in accordance with ASC No. 820 at level 2. The net losses recognized in "financial and other expenses, net" during 2009 and 2008 were $ 52 and $ 0, respectively.

As of December 31, 2009 and 2008, the Company had outstanding forward contracts in the amount of $ 15,443 and $15,709, respectively.

The fair value of our outstanding derivative instruments as of December 31, 2009 and 2008 and the effect of derivative instruments in cash flow hedging relationship on other comprehensive income for the years ended December 31, 2009 and 2008 are summarized below:

SUBSEQUENT EVENTS

On March 31, 2010, the Company reached an agreement in principle to settle the Company’s securities class action litigation. Pursuant to the terms of the agreement, the Company will pay to the plaintiffs, for the benefit of the class members, $1.3 million in cash, which amount is to be funded by the Company's insurance carrier. The settlement contemplated therein is conditional upon approval by the court and other contingencies. There is no assurance that final court approval will be obtained. If such approval is not obtained, the parties to this litigation may attempt to reach agreement on alternative settlement terms or resume the litigation. The Company has recorded a liability in its financial statements for the proposed amount of the settlement. In addition, because the insurance carrier has agreed to pay the enti re settlement amount and recovery from the insurance carrier is probable, a receivable has also been recorded for the same amount. Accordingly, there is no impact to the Company’s statements of operations or cash flows because the amounts of the settlement and the insurance recovery fully offset each other (See Note 9c).
