The forward-looking statements contained in this Annual Report and the documents incorporated herein by reference are based on our current expectations, estimates, approximations and projections about our
industry and business, managements beliefs, and certain assumptions made by us, all of which are subject to change. Forward-looking statements can often be identified by words such as anticipates, expects,
intends, plans, predicts, believes, seeks, estimates, may, will, should, would, could, potential,

impact they will have on our results of operations and financial condition. Except as required by law, we undertake no obligation to revise our forward-looking statements to reflect events or circumstances that arise after the date of this Annual
Report or the respective dates of documents incorporated herein by reference that include forward-looking statements. Thus, you should not assume that our silence over time means that actual events are bearing out as expressed or implied in these

PART I



|Item 1. | Business
|------- | --------

Overview

Entropic Communications is a leading fabless semiconductor company that designs, develops and markets systems solutions to enable connected home
entertainment. Our technologies significantly change the way high-definition television-quality video, or HD video, and standard-definition television-quality video, or SD video, and other multimedia content such as movies, music, games and photos
are brought into and delivered throughout the home.

We are a pioneer of key technologies that enable connected home networking of
digital entertainment over existing coaxial cable. We are a founding member of Multimedia over Coax Alliance, or MoCA, a global home networking consortium that sets standards for the distribution of video and other multimedia entertainment over
coaxial cable. Our products include integrated circuits and related software associated with:



| |  |  | home networking solutions based on the MoCA standard;
| | - |  | -----------------------------------------------------



| |  |  | direct broadcast satellite, or DBS, services;
| | - |  | ---------------------------------------------



| |  |  | high-speed broadband access; and
| | - |  | --------------------------------



| |  |  | silicon tuners.
| | - |  | ---------------

Our products
allow telecommunications carriers, cable operators and DBS service providers, which we collectively refer to as service providers, as well as providers of over-the-top, or OTT, services, to enhance and expand their service offerings and reduce
deployment costs in an increasingly competitive environment.

Our home networking solutions capitalize on the worldwide conversion of
multimedia content, including video, from analog to digital. Multimedia content is now easy to store on digital video recorders, or DVRs, gaming consoles, digital versatile disk, or DVD, recorders, personal computers, portable devices and
Internet-hosted services, also referred to as the cloud. The ability to store this content on various devices has created islands of digital entertainment within the home. Our products bridge these islands and allow consumers
to access their multimedia content throughout the home. Our MoCA-compliant chipsets can be embedded in a wide variety of consumer electronic devices. Service providers can employ our solutions to offer consumer applications such as multi-room DVR,
online gaming, personal computer-to-television content sharing and streaming of downloaded movies stored on a personal computer or the cloud to a television. Additionally, products incorporating our MoCA solutions can be purchased directly by
consumers to connect consumer electronic devices within the home such as personal computers, televisions and game consoles to the homes broadband connection such as digital subscriber line, or DSL, routers or cable modems and passive optical
networks, or xPONs, and thereby enable the devices to benefit from OTT services that are made available on the Internet. Our MoCA home networking solutions are now being deployed into consumer homes to support multi-room DVR service by Comcast Corp,
or Comcast, Cox Communications, Inc., or Cox, DIRECTV Holdings LLC, or DIRECTV, Time Warner Cable Inc., or Time Warner Cable, and Verizon Communications, Inc., or Verizon, as well as by a number of smaller service providers.

We have extensive core competencies in video communications, networking algorithms and protocols, system-on-a-chip design, embedded software, mixed
signal and radio frequency integrated circuit design, and communications and radio frequency systems. We use our considerable experience with service provider-based deployments to create solutions that address the complex

requirements associated with delivering multiple streams of HD video into and throughout the home while seamlessly coexisting with video, voice and data services that are using the same coaxial
cable infrastructure.

Industry Background

Intense competition among service providers and OTT service providers seeking to maximize revenues is driving a revolution in the delivery of video and other multimedia content into and throughout the home.
According to research by IMS Research, or IMS, the number of U.S. pay-television households with HD video is expected to grow from 48 million in 2010 to approximately 86 million by 2014, representing a compound annual growth rate of
approximately 15.5%. These service providers are making significant infrastructure investments to differentiate their offerings by adding new video services such as HD video, video-on-demand and multi-room DVR, as well as bundled video, voice and
broadband data, or triple-play, services. In fact, consumers typically pay a higher price for video services than for traditional voice and broadband services. A successful video offering is critical for service providers to increase
average revenue per user, drive subscriber growth and reduce subscriber turnover.

Several favorable consumer entertainment trends are
contributing to the increasing video and multimedia revenue opportunity for service providers and OTT service providers. These trends include:



| |  |  | Increasing availability of digital multimedia content.    The conversion of multimedia content from an analog to a digital format, the
increasing number of broadcast content providers who make their video content available for online video streaming, and the introduction of three dimensional, or 3D, video content, are significantly increasing the amount and variety of video, music,
photos and other multimedia content that consumers buy, receive and store.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Proliferation of connected digital multimedia devices within the home.    As a result of the increasing availability of multimedia
content from sources inside the home and from the Internet, connected digital multimedia devices such as high-definition televisions, or HDTVs, desktop and laptop personal computers, DVD players, Blu-ray players, portable media players, gaming
consoles, DVRs and OTT set-top boxes can now be found in U.S. households in increasing numbers.

| |  |  | Introduction of new multimedia applications.    An increasing number of multimedia applications utilize digital video and other
multimedia content for consumer home entertainment. Some examples of these applications include video time shifting, or the ability to pause, fast forward and rewind live or stored video, the ability to watch and record multiple
television shows at once, video or movie on demand, personal computer-to-television content sharing, multi-room and online gaming, streaming of downloaded movies stored on a personal computer to a television, and OTT services that directly deliver
Internet video content into the home.

| |  |  | Increasing consumer adoption of OTT services.    Consumer demand for fully customizable viewing experiences that allow them to select
the time, place and content has increased the availability of OTT services such as those offered from AppleTV, Boxee, GoogleTV, Netflix and Vudu, all of which benefit from having a high-speed, highly reliable network connection to digital multimedia
devices, such as connected HD video and game consoles, within a home.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

These trends have resulted in a growing
number of islands of stored multimedia content within the home, including SD video and HD video, movies, broadcast television programs and personally created content. Service providers and original equipment manufacturers, or OEMs, have
identified opportunities to seamlessly bridge these islands and enable the sharing of such content across devices and between rooms throughout the home. At the same time, as the popularity of online video streaming continues to grow,
broadcast service providers recognize the growing need to provide combined broadband and broadcast services to retain their existing subscribers. To address this opportunity and meet evolving customer expectations, service providers are introducing
new customer premises equipment and service offerings such as multi-room DVR, which allows for video placeshifting, or the ability to access content from multiple locations and devices, and a new class of devices that connect the coaxial
network in the home to online services. By providing more advanced customer premises equipment, service providers are able to more easily introduce new services, simplify and enhance the user experience, and maintain content security and service
reliability. We believe service providers are competitively positioned to provide these services because they already have licensed access and distribution rights to premium video content and have established the infrastructure that enables carrier
class quality-of-service, or QoS.

The stringent communications requirements associated with high-quality HD video, 3D video and other
multimedia content present a significant challenge for service providers today. In response, service providers require solutions that enable the distribution of such content into and throughout the home while maintaining the high-quality standards
demanded by subscribers. For any such technology solution to succeed, we believe it must satisfy the following requirements:



| |  |  | High bandwidth, reliability and full QoS for HD video.    Due to the fact that video is typically a streaming, real-time, visual
experience, video quality can rapidly degrade with errors or delays in packet delivery. A high-quality video experience requires reliable first-pass transmission, very low packet error rate, low latency and low jitter. Moreover, video consumes up to
10 times more bandwidth than typical voice and data services and has higher QoS requirements. A connected home with capacity to support multiple high-quality HD video streams requires a high bandwidth network with net throughput in excess of 100
megabits per second for todays services, which is believed to be increasing to greater than 250 megabits per second for services planned in the future.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Cost-effective deployment.    It is important for service providers to leverage the existing installed network infrastructure inside
and outside the home to minimize incremental cost and expedite new service deployments. Service providers prefer plug-and-play installation of new services as opposed to having to dispatch a service vehicle to customer premises, often referred to as
a truck roll. Service providers are focused on saving installation time and minimizing customer service calls, thereby reducing total costs to deliver video services. In some cases, service providers may install customer premise
equipment that is capable of providing services that are not ordered by the customer at the time of installation but which may be switched on remotely at a later time, thereby potentially avoiding the need for future truck rolls.

| |  |  | Customer ease of use.    Most consumers have little tolerance for complicated devices and service disruptions. Therefore, mainstream
consumer adoption requires an easy to use and compelling service offering and plug-and-play service installation with minimal ongoing maintenance.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Co-existence with other services and devices.    Consumers currently subscribe to a broad array of communications services, including
traditional voice, broadcast television, broadband access and cellular wireless services that are delivered using a number of different technologies. In addition, consumers may use a multitude of computing, communications and consumer electronics
devices, such as personal computers, video players, gaming consoles, set-top boxes and televisions. Any successful home networking or access solution must seamlessly co-exist with existing services and devices with minimal interference or
degradation in performance.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Security.    The ability to ensure the secure delivery of content and consumer privacy is a key element of any successful bundled
service offering. Therefore, home networking and access solutions require data encryption and other security mechanisms.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

To address these requirements, service providers are exploring home networking and access technology platforms that enable delivery of new services into and throughout the home. There are a variety of other
technologies for delivering video into and throughout the home. Broadband access technology solutions include data over cable service interface specifications, or DOCSIS, versions of Digital Subscriber Line, or xDSL, Ethernet, xPON, 3rdGeneration Partnership Project Long Term Evolution and Worldwide Interoperability for
Microwave Access, or WiMAX. Home networking technology solutions include Ethernet, G.hn, HomePNA, HomePlug, HomePlug AV, HD-PLC, IEEE P1901 and Wi-Fi. We believe each of these other technologies currently have limitations in meeting all the
requirements necessary to effectively deliver multiple streams of SD video, HD video and 3D video and other multimedia content into and throughout the home.

Our product lines include home networking, broadband access, DBS outdoor unit solutions and silicon tuners. Our solutions target applications in HD
video and other multimedia content distribution networks through cable, satellite, telecommunications and terrestrial mediums. Our solutions are currently used in consumer electronic and service provider customer premises equipment, including
set-top boxes, broadband routers, optical network terminals, low-noise block converters, multi-room DVRs, residential gateways and Ethernet-to-coax adapters, and can potentially be used in other devices, such as digital televisions, gaming consoles,
connected HDTVs, OTT set-top-boxes, media servers and network attached storage devices.

Home Networking

Our home networking solutions target a large and rapidly growing market. Our home networking solutions are based on the MoCA standard. We are a
founding member of MoCA, which was established in 2004 and includes as its members many major service providers, communications equipment companies, semiconductor manufacturers and consumer electronics companies. MoCA-based products use existing
coaxial cable to create a robust Internet protocol-based network for easy sharing of HD video and other multimedia content throughout the home. MoCA is being deployed as the home networking standard for Verizons FiOS offering and for
high-definition set-top boxes, or HD set-top boxes, for DIRECTV, Comcast, Time Warner Cable, Cox and other cable service providers. We believe that additional service providers are in the process of evaluating, adopting or deploying MoCA-based
technology for digital home entertainment networking.

The implementation of home networking chipsets based on the MoCA specification
requires expertise in multiple technical disciplines as well as extensive integration and testing. Any home network technology using the existing coaxial cable must overcome the inherent constraints of such infrastructure. The in-home coaxial cable
network was designed to isolate individual cable outlets from each other in order to eliminate potential video signal interference between television sets that reside at different coaxial cable outlets in the home. The successful implementation of
MoCA requires integrated circuits that support high wire speed signal transmission and enable low-level signal detection, real-time error correction and recovery. The broad range of expertise required for such implementation includes physical layer
and media access controller system engineering, radio frequency integrated circuit and high-speed mixed signal design, complex baseband system-on-a-chip experience and embedded software expertise. In addition, MoCA designs must undergo a formal
certification process in order to ensure interoperability and full compliance with the MoCA specification.

##### Table of Contents

We have been working on home networking technologies on which the MoCA specification is based since
2001 and began shipping production quantities of MoCA-compliant chipsets in December 2004. In September of 2009, we began shipping our third generation of MoCA-compliant products and we recently announced the first complete MoCA 2.0
solution. Our MoCA-compliant chipsets are incorporated in equipment being deployed by Verizon, DIRECTV, Comcast, Time Warner Cable, Cox and other service providers. Our MoCA-compliant products can be used to support on demand video services,
online video streaming services, personal computer-to-television content sharing, multi-room DVR and online gaming. We see a growing need for a highly reliable wired home networking solution to support these new multimedia applications. We believe
that our new MoCA 2.0 chipset will answer the growing demand for powerful connectively within the home.

We believe that our pioneering
role in developing the MoCA standard and our success to date in providing these solutions position us well to continue to be the leading provider of MoCA- compliant connected home entertainment solutions. Our MoCA-compliant home networking solutions
provide the following key benefits:



| |  |  | High data rates.    In field trials defined and conducted by MoCA, our first generation solutions consistently delivered net
throughput in excess of 110 megabits per second in real world conditions with no loss in performance when multiple devices were connected to the network. This performance enables sharing of multiple simultaneous streams of HD video. Our second and
third generation solutions continue to have a physical layer rate of up to 250 megabits per second and have increased net throughput to up to 175 megabits per second. With our MoCA 2.0 solutions, we expect to have a physical layer rate of 600
megabits per second and an increased net throughput of up to 400 megabits per second in its basic configuration and up to 500 megabits per second between two devices in turbo mode as described in the MoCA specification. MoCA 2.0 also
supports channel bonding to yield net throughputs between 800 megabits per second and 1 gigabit per second. The physical layer rate refers to the maximum speeds of the physical layer of our integrated circuits, while net throughput refers to the
rate at which data is actually made available to applications and experienced by users.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | High-quality video experience.    Our solutions provide a reliable and high-quality video experience for the consumer that meets
service provider requirements. Our solutions operate at frequencies on the coaxial cable that do not interfere with other services or devices. Our physical layer and media access controller provide a very low native packet error rate, without the
need for retransmissions, that is essential for service provider-quality HD video. Our media access controller is time coordinated, which eliminates collisions in the network. Our solution also provides two methods of ensuring QoS, prioritized QoS
and reserved bandwidth scheme, namely parameterized QoS.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Ease of installation and use.    Our solutions leverage the existing coaxial cable infrastructure and do not require expensive new
wiring in the home. The plug-and-play installation of our solutions makes it easy for consumers to install and use, and allows service providers to rapidly deploy, new services. Both of these features enable service providers to minimize costly
truck rolls.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Security and reliability.    Our solutions operate on coaxial cable, which is a shielded, wired medium that can be simply isolated
from neighboring home networks through both logical and physical means. We support service provider-based conditional access systems and related digital rights management and provide basic encryption for consumer privacy of personal multimedia
content. In addition, our solutions create a self-healing network that provides high levels of fault tolerance and reliability.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Remote upgrade and diagnostics.    Our solutions allow service providers to remotely upgrade firmware which gives them the ability to
continuously enhance the features of their

| | service offerings without truck rolls. Our solutions remote diagnostics tools also allow service providers to remotely diagnose and potentially remediate the home coaxial cable environment.
| | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

DBS Outdoor Unit

Our DBS outdoor unit solutions target the large and growing digital broadcast satellite market. In a traditional satellite installation, the ability to select multiple channels simultaneously frequently requires
multiple cables from the satellite dish to the set-top box. For example, in order to simultaneously view and record separate programs from the full channel lineup with DVRs in three rooms in a house, a user typically needs six separate cables from
outside the home. Our DBS outdoor unit products can significantly reduce the deployment costs for digital broadcast satellite providers by allowing them to send multiple video streams from individual or multiple satellites into the home over a
single cable. This simplified cabling architecture enables digital broadcast satellite providers to deploy set-top boxes, with multiple tuner capabilities, in multiple rooms and roll out new services without expensive installation and retrofitting
while at the same time improving aesthetics of the home by not damaging walls while installing multiple cables. We believe that our solutions can improve the competitiveness of digital broadcast satellite services by reducing subscriber acquisition
costs, decreasing deployment costs for additional services and enabling a more attractive product offering.

Our DBS outdoor unit
products include band translation switch and channel stacking switch integrated circuits, which are highly complex single-chip radio frequency integrated circuits that integrate multiple independent signal receivers and multiple discrete analog
functions onto a single silicon die. Moreover, as many as four channel stacking switch integrated circuits can be linked to provide up to 12 digital broadcast satellite signals on a single cable. Our band translation switch products, which were
specifically designed to operate with DISH Network Corporations, or DISH Networks, service offerings, are sold to customers who incorporate them into products deployed by DISH Network. We sell our channel stacking switch products to
customers who incorporate them into products deployed by other DBS service providers. We are the pioneers in developing band translation switch and channel stacking switch radio frequency integrated circuits and we have helped to define the standard
for satellite signal distribution over a single cable in conjunction with members of the European Committee for Electrotechnical Standardization, or CENELEC. We believe that single cable standardization will lead to more rapid adoption and further
expand the market for our products. Our band translation switch products are currently used in outdoor equipment deployed by DISH Network and one other North American operator and our channel stacking switch products are currently used in outdoor
equipment deployed by DIRECTV, Via Embratel, Sky Italia, BSkyB and other service providers.

Broadband Access

Our broadband access solutions are designed to meet broadband access requirements in areas characterized by fiber optic networks that terminate
within one kilometer of a customer premises. In particular, our solutions allow cable service operators with fiber optic deployments to offer broadband triple-play services that are competitive with very high-speed digital subscriber line, or VDSL,
services offered by telecommunications carriers. We believe that this is a large potential target market for our broadband access products and we have several deployments underway with service providers in China. Our broadband access solutions also
have applications in vertical markets beyond broadband residential access. Our broadband access solutions are being deployed in video surveillance products operating over coax infrastructure in point to multi-point topologies. In addition, our
broadband access solutions have been incorporated into systems currently under evaluation in hospitality networks, providing video and broadband services over coax to multiple hotel residents.

Our broadband access solutions use coaxial cable infrastructure to deliver last kilometer
connectivity for high-speed broadband access to single-family homes and multiple dwelling units. They incorporate the same physical layer used in our home networking products and a different network-optimized media access controller technology. Our
broadband access solutions offer high performance with net throughput in excess of 100 megabits per second. The point-to-multi-point architecture of our solutions currently supports up to 63 subscribers on a single radio frequency channel. Our
solutions are capable of supporting up to four simultaneous channels over a single coaxial cable. As a result, a single distribution cable could support up to 252 subscribers with net throughput ranging from 340 to over 500 megabits per second. Our
high-speed broadband access solutions enable service providers to offer bundled triple-play services over their existing services and cable infrastructure.

Silicon Tuner

We provide silicon tuner integrated circuits for cable and terrestrial
applications that conform to most major digital and analog video broadcast standards, including the U.S. and international broadcasting standards. Many set-top boxes and integrated digital televisions have multiple tuners to enable advanced features
such as DVR, watch-and-record functionality and picture-in-picture viewing, further expanding the market for tuner integrated circuits. Our tuner integrated circuits integrate radio frequency functions, including those performed by a surface
acoustic wave, or SAW, filter, with other major discrete components onto a single die while maintaining the performance of traditional non-silicon can tuners. Our highly integrated solutions significantly reduce our customers design costs and
shrink the tuner footprint in consumer electronics devices. We believe that the performance and small footprint of our tuners will lead to greater adoption of multiple-tuner applications across a broad range of consumer electronics over time.

Our Strategy

Our goal is to be
the leading provider of systems solutions for the connected home entertainment market by enabling the delivery of multiple streams of HD video and other multimedia content into and throughout the home. The key elements of our strategy are to:



| |  |  | Extend our technology leadership.    We believe that our success has been, and will continue to be, largely attributable to our
interdisciplinary skill set that we leverage to create innovative systems-level solutions. As the incumbent supplier of key MoCA-compliant technologies in service provider-based deployments, we gain critical insight into next generation product and
system requirements. We have and will continue to use these insights to enhance our products. For example, as a result of our leadership in developing MoCA 1.0 and 1.1 compliant solutions, we were a leading contributor to the development of the next
generation MoCA 2.0 specification, which was adopted by MoCA in June 2010. We intend to extend our technology leadership by focusing on our research and development efforts and through targeted technology acquisitions.

Our Technology

We believe that we possess the expertise and experience, breadth and depth of technologies, and the skills required to address and compete effectively in our target markets. These capabilities result from our
in-depth understanding of the environments in which we operate, knowledge and experience with customer and operator requirements, and extensive communications system understanding.

Home Networking

Our home networking products are based on an innovative platform
technology that allows very high-speed and reliable communications between coaxial cable home outlets without the need to modify the home coaxial cable system and without interfering with existing cable television services. This technology has been
designed to address the very difficult communications environment of the coaxial cable home network architecture. We have developed an in-depth understanding of the home coaxial cable environment as a result of extensive testing and characterization
of both the coaxial cable home network and its components, such as splitters, cables, taps and home entertainment devices including television sets and set-top boxes. These tests provided us with a large database of home coaxial cable network
characteristics from which we have developed a set of tools and models that we use to optimize our solutions for this environment.

Coaxial home cabling is designed for vertical communications to and from the cable system head-end to the devices connected to coaxial
cable outlets in the home, such as television sets and set-top boxes, and has in the past primarily been used for the delivery of cable television, data (cable modem) and, more recently, voice over Internet protocol services, or VoIP. The in-home
coaxial cable architecture has been specifically designed to prevent inter-outlet communications through the use of splitters with high port-to-port isolation. This leads to a highly dispersive physical layer channel, over which it is difficult for
typical digital communication systems to operate. The historical inability to address these issues associated with in-home coaxial cable architecture has contributed to the creation of islands of digital entertainment within the home.

Our home networking technology is a full-mesh, peer-to-peer network. It overcomes the inherent limitations of home coaxial cable and
enables high-speed horizontal communications between the outlets in cable homes. This is accomplished through a combination of an adaptive physical layer that optimizes the signal modulation in order to maximize the channel capacity of
the in-home coaxial cable network and a unique media access controller protocol that maintains very low latency independent of network load by allocating channel resources without contention or retransmission. The system simplifies installation and
maintenance requirements through the use of an ad-hoc network controller functionality, which makes the network self-healing and provides redundancy. Our home networking solution is implemented using an efficient and flexible architecture through an
optimized combination of hardware, firmware, software and cost effective radio frequency integrated circuit and system-on-a-chip implementations.

Our home networking technology was selected as the basis for the first generation MoCA standard for home networking over coaxial cable after a selection process that involved an extensive and successful field trial
conducted by MoCA. The field trial demonstrated that our home networking technology repeatedly achieved a very reliable net throughput in excess of 110 megabits per second at acceptable packet error rate levels to support in-home video distribution
at quality levels appropriate for service provider-based pay-television deployments. This net throughput allows for the simultaneous delivery of more than four full-rate HDTV channels and other services, such as voice and data.

In 2007, MoCA adopted and approved its second generation of specifications, known as MoCA 1.1, which
addressed the evolving needs of service providers for more bandwidth, increased device support and guaranteed QoS. Our EN2210 and EN2510 solutions deliver a net throughput of up to 175 megabits per second, support up to 16 nodes, provide
parameterized QoS and offer security through the use of a shielded, wired connection in combination with state of the art packet-level encryption technology. The components of our EN2210 and EN2510 products are designed to easily and
cost-effectively distribute multiple streams of HD quality video entertainment via a highly reliable home network. On June 15, 2010, the MoCA 2.0 standard was adopted by MoCA. MoCA 2.0 offers two performance modes, basic and enhanced, with net
throughput of 400 megabits per second and 800 megabits per second, respectively.

DBS Outdoor Unit

Our DBS outdoor unit solutions simplify the installation required to support simultaneous reception of multiple channels from multiple satellites
over a single cable. This capability is critical to allow a satellite receiver to enable picture-in-picture viewing or to record and watch two or more programs simultaneously, using a single cable. In cable television systems, all the channels are
available over the coaxial cable connected to the television set or the cable set-top box. In satellite systems, the number of channels available from multiple satellites typically exceeds the channel carrying capabilities of the connecting cable.
The channel stacking switch and band translation switch technologies are designed to select desired satellite channels and re-arrange them for delivery to the indoor set-top box over a single connecting cable. This single cable connects the outdoor
unit to either many set-top boxes in and around the home or a media center inside the home, and delivers all the programs being viewed on the various devices inside the home. In a legacy system that does not use the channel stacking switch and band
translation switch technologies, additional cables may be required as the numbers of simultaneously viewed satellite channels or the number of simultaneously viewed programs increases.

The implementation of such complex radio frequency processing in an integrated radio frequency integrated circuit is accomplished with our radio
frequency system architecture and design capabilities, including the design of multiple, independently operable, low noise oscillators on a single die, cross-point switching and high isolation techniques realized in both circuit design and advanced
floor planning methodologies.

Broadband Access

Our broadband access solutions use coaxial cable infrastructure to deliver last kilometer connectivity for high-speed broadband access to single-family homes and multiple dwelling units. Our solutions
are designed to work on passive coaxial cable networks. This means that a fiber node in the hybrid fiber coaxial, or HFC, network, or the xPON terminates at the last active device in a coaxial cable wide area network. This termination point is
typically within 600 meters of a customers premises. For active or passive coaxial cable distribution plants extending up to 1.2 kilometers, cable operators can use a c.LINK-compliant distribution amplifier which increases coverage while
delivering the same throughput performance. Our solutions are based on our c.LINK access technology and provide efficient communications between an access node, such as a fiber termination in the basement of an apartment building, and the cable
outlets in each apartment throughout the building. Other applications of our broadband access solutions can be supported in similar cable infrastructure topologies. For example, our broadband access solutions are being deployed in video surveillance
products operating over coax infrastructure in point to multi-point topologies. In addition, our broadband access solutions have been incorporated into systems currently under evaluation in hospitality networks, providing video and broadband
services over coax to multiple hotel residents.

Our c.LINK access technology utilizes a single radio frequency channel for communicating in both the
upstream and downstream directions. This allows flexibility in the allocations of bandwidth transmitted in either direction. For example, if a user has a significant amount of information to send from a computer, such as
video files or photos loading to a server on the Internet, the c.LINK access technology can allocate the available bandwidth for the requisite time duration to this upstream direction. Also, since the access node device and the customer
devices do not transmit and receive simultaneously, the access node device can share much of the front-end circuitry for both transmit and receive functions, resulting in additional cost savings. Since communications to different nodes in the
network and to or from each device are accomplished through the time division of the radio frequency channel, a single device using our c.LINK access technology at the access node can communicate with as many as 63 customer devices, resulting in a
cost-effective solution for high-speed broadband access. The time division protocol also provides each customer device a deterministic time slot to access the network. It guarantees true QoS under a variety of traffic conditions. Our solution is
also able to simultaneously support up to four channels over a single coaxial cable. As a result, our solution is scalable up to 252 subscribers over a single distribution cable supporting an effective physical layer rate of over 1 gigabit per
second. In addition to scalability, our c.LINK access technology can operate in a wide range of operating frequencies between 800MHz and 1500MHz.

Silicon Tuners

Our radio frequency
technology is well suited for the design of low-cost, high-performance, low-power and small footprint, terrestrial and cable, single and multiple tuner integrated circuits. Our silicon tuner integrated circuits integrate radio frequency functions,
including those performed by a SAW filter, with other major discrete components into a single die while maintaining the performance of traditional non-silicon can tuners. Our system architecture is capable of addressing todays legacy standard
interfaces to digital demodulation integrated circuits, and at the same time is optimized for future interfaces. This architecture is also ideal for an integrated, multiple tuner, single integrated circuit implementation. Our low noise, high dynamic
range front-end and low phase noise design combined with the integrated, tunable, high selectivity radio frequency filters ensures that we can meet the stringent requirements of both digital and analog terrestrial and cable applications. Our
fully-integrated, auto-calibrated, analog signal processing and high isolation techniques, including advanced floor-planning methodologies, enable us to design multi-standard, multiple tuners on a single silicon die.

Our new generation of silicon integrated circuit tuners provide a single hardware platform that is software localized for different markets. This
new generation silicon tuner significantly increases manufacturing and test efficiency for our customers by allowing them to produce a single hardware platform, thus streamlining the procurement and manufacturing process to enable net cost savings.

We use third-party foundries and assembly and test contractors to manufacture, assemble and test our products. This outsourced manufacturing
approach allows us to focus our resources on the design, sales and marketing of our products and avoid the cost associated with owning and operating our own manufacturing facility. Our engineers work closely with foundries and other contractors to
increase yields, lower manufacturing costs and improve quality.

We currently outsource the manufacturing of our home networking and our
broadband access products, principally to Taiwan Semiconductor Manufacturing Company, or TSMC, and the manufacturing of our DBS outdoor unit and silicon tuner products to TowerJazz, the name under which Tower Semiconductor Ltd. and its fully owned
U.S. subsidiary Jazz Semiconductor operate. Our products are shipped from such third-party foundries to third-party assembly and testing facilities. Our home networking and our broadband access chipsets are primarily assembled and tested by Amkor
Technologies, Inc., or Amkor, while our DBS outdoor unit and silicon tuner products are primarily assembled by Amkor and tested by Giga Solution Tech. Co., Ltd., or Giga Solution. We have implemented a robust quality management system designed to
assure high levels of product quality for our customers. We have completed and have been awarded ISO 9001:2000 certification. In addition, the independent foundries, assembly and test subcontractors identified above have been awarded ISO 9001:2000
certifications, among others.

Sales and Marketing

We sell our products worldwide through multiple channels, including our direct sales force and our network of domestic and international sales representatives and distributors. We have strategically located our
direct sales personnel in the United States, Europe, China, Taiwan, Japan and Korea, where each salesperson has specific end-user market expertise. Our sales directors focus their efforts on leading ODMs and OEMs. We also have field application
engineers who provide technical support and assistance to existing and potential customers in designing, testing, qualifying and certifying systems that incorporate our products.

Our sales and marketing strategy is to achieve design wins with leading ODMs and OEMs and mass deployment of our solutions with service providers
worldwide. This requires us to work extensively and collaboratively with our ODM and OEM customers as well as the service providers who purchase products from them. As a result, we believe that our established relationships allow us faster time to
market and will lead to greater proliferation of our products.

Our marketing group focuses on our product strategy and management,
product development roadmaps, product positioning, new product launch and transition, demand assessment and competitive analysis. The group also ensures that product development activities, product launch, channel marketing program activities, and
ongoing demand and supply planning occur in a well-managed and timely manner in coordination with our development, operations and sales groups as well as our service provider representatives, ODMs and OEMs. Our marketing group also has programs in
place to work closely with service providers in the role of a trusted advisor for MoCA deployments and initiatives designed to heighten industry awareness of our company, products and technologies, including participating in technical
conferences, support of industry initiatives such as MoCA, publication of technical white papers and exhibition at trade shows.

Backlog

Our sales are made primarily pursuant to standard purchase orders for delivery of products. Quantities of our products to be
delivered and delivery schedules are frequently revised to reflect changes in our customers needs. Additionally, customer orders generally can be canceled or rescheduled without significant penalty to the customer. For these reasons, our
backlog of product inventory as of any particular date is not representative of actual sales for any succeeding period and, therefore, we believe that our backlog is not necessarily a reliable indicator of future net revenue levels.

Competition

The markets for our products
are extremely competitive and are characterized by rapid technological change, evolving industry standards and new demands for features and performance of multimedia content delivery solutions. We believe the principal competitive factors in our
markets include the following:



| |  |  | the adoption of our products and technologies by service providers, ODMs and OEMs;
| | - |  | ----------------------------------------------------------------------------------



| |  |  | the performance and cost effectiveness of our products relative to our competitors products;
| | - |  | ---------------------------------------------------------------------------------------------



| |  |  | our ability to deliver high quality and reliable products in large volumes and on a timely basis;
| | - |  | -------------------------------------------------------------------------------------------------



| |  |  | our ability to build close relationships with service providers, ODMs and OEMs;
| | - |  | -------------------------------------------------------------------------------



| |  |  | our success in developing and utilizing new technologies to offer products and features not previously available in the marketplace that are technologically
superior to those offered by our competitors;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| |  |  | our ability to identify new and emerging markets and market trends;
| | - |  | -------------------------------------------------------------------



| |  |  | our ability to recruit design and application engineers and other technical personnel; and
| | - |  | ------------------------------------------------------------------------------------------



| |  |  | our ability to protect our intellectual property and obtain licenses to the intellectual property of others on commercially reasonable terms.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------

We believe that we compete favorably with respect to each of these criteria. However, conditions in our markets could
change rapidly and significantly as a result of technological advancements or the adoption of new standards for the delivery of HD video and other multimedia content. In addition, many of our current and potential competitors have longer operating
histories, significantly greater resources, stronger name recognition and a larger base of customers than we do. This may allow our competitors to respond more quickly than we are able to respond to new or emerging technologies or changes in
customer requirements or it may allow them to deliver products that are priced lower than our products or which include features and functions that are not included in our products.

In the market for home networking solutions, we are currently the only deployed high-volume supplier of MoCA-compliant chipsets. In the near-term,
therefore, we believe our primary competition in this market will be from companies that offer products based on non-MoCA home networking solutions, such as Ethernet, HomePNA, Home Plug AV and Wi-Fi, and potentially G.hn when products incorporating
the standard for that technology are introduced to the market. However, Broadcom Corporation, or Broadcom, has announced the availability of several multi-format video decoder system-on-a-chip solutions, or SoC, with integrated MoCA functionality as
well as SoC solutions that incorporate xPON technology with integrated MoCA functionality. Broadcoms home networking reference designs have achieved MoCA 1.0 and MoCA 1.1 certification from the MoCA certification board. We have been competing
with Broadcom integrated MoCA solutions and expect to continue to compete with Broadcom and other semiconductor manufacturers in the manufacture and sale of MoCA-compliant chipsets in the future. In the broadband access market, our broadband access
products compete with other, more well-established high-speed wide area networking technologies such as DOCSIS, xDSL, xPON and WiMAX. While we believe that our products compete favorably against alternative technologies in these markets, the
ultimate competitiveness of our products is highly dependent on, and sensitive to, the particular facts and circumstances of each service provider and its end user customers, such as the type of media content being distributed, the environment in
which the distribution is taking place, the available network bandwidth and distribution mediums, and the number of devices connected to a network. In the DBS market, our band translation switch and channel stacking switch products face competition
from discrete solution providers and other semiconductor manufacturers. In the market for tuners, our silicon tuners face competition from silicon and non-silicon tuners that offer similar functionality. In the transition to and adoption of CMOS
technology to deliver silicon tuners, we believe that we are currently the market leader in compliance with existing standards and quality of performance. As the integrated silicon tuner market is maturing, the number of competitive players in the
market is being reduced and other competitive offerings will become available.

Intellectual Property

Our success and future revenue growth depend, in part, on our ability to develop and protect our intellectual property. We rely primarily on patent,
copyright, trademark and trade secret laws, as well as nondisclosure agreements and other methods, to protect our proprietary technologies and processes. However, these measures may not provide meaningful protection for our intellectual property. We
review our technological developments to identify features that provide us with a technological or commercial advantage and we file patent applications when we deem it to be appropriate to protect these features in the United States and
internationally in select countries. In addition to developing patented technology internally, we continually evaluate the acquisition and

licensing of intellectual property from third-parties that complement our business. As of December 31, 2010, we held 47 issued U.S. patents, one of which was reexamined by the U.S. Patent
and Trademark Office and for which a reexamination certificate was issued. In addition, as of December 31, 2010, we had 47 foreign patents and another 198 patent applications that were pending in the United States and foreign countries, of
which nine applications have been allowed. The term of an issued patent in the United States is at least 20 years from its filing date, unless subject to a terminal disclaimer. The U.S. Patent and Trademark Office provides term extensions for those
applications that have been pending for more than three years and for which the duration of the pendency is not the fault of the applicant. Accordingly, many of our patents may receive a longer term due to the benefit of such patent term extensions.
Taking such patent terms and any terminal disclaimers into account, the remaining terms of our issued U.S. patents range from 12 to 17 years and the remaining terms for counter-part patents in most foreign jurisdictions are similar, provided we pay
the applicable maintenance fees throughout the terms of our issued U.S. and granted foreign patents.

We are the owner of several
registered trademarks in the United States and in certain foreign countries, including Entropic, Entropic Communications, c.LINK and RF Magic.

In connection with our membership in MoCA, we are required to license any of our patent claims that are essential to implement the MoCA
specification to other MoCA members under reasonable and non-discriminatory terms. Because our core home networking technology is a primary component of the MoCA specification, we are required to license portions of this technology to other MoCA
members, including other semiconductor manufacturers that may compete with us in the sale of MoCA-compliant chipsets. However, only essential patent claims necessary to implement the MoCA specification are subject to this requirement. We are not
required to license patent claims that are not essential to implement the MoCA specification, nor are we required to license patent claims that are unrelated to the MoCA specification. To date we have not entered into a license of our MoCA-related
patent claims, so the terms of any required license have not been established.

In addition to the licensing requirements of standards
bodies to which we belong, such as MoCA, in connection with our sales or product development activities, we are also sometimes required by our customers or service providers to license to unrelated third-parties, on reasonable and non-discriminatory
terms, patents and patent applications associated with technologies purchased or used by, or developed with or for, such customers or service providers. We expect that in the future we may be required to agree to such licensing arrangements in order
to secure sales, receive development funds or settle disputes.

In addition to our patent rights, we hold significant intellectual
property in the form of proprietary trade secrets which we rely on to compete. Designing integrated circuits that comply with the MoCA specification or implement our DBS outdoor unit solutions is technically difficult and requires the application of
a wide range of complex engineering disciplines. During the course of creating the technology on which the MoCA standard is based, we developed significant proprietary know-how and techniques for overcoming the engineering challenges involved in
designing MoCA-compliant products. We retain such know-how and techniques as proprietary trade secrets that we are not required to license to others as a result of our membership in MoCA. Similarly, we have developed significant proprietary know-how
and techniques for implementing our DBS outdoor unit solutions in satellite installations. Consequently, even though we are required to license patent claims that are essential to implement the MoCA standard to other MoCA members and have agreed to
license patents and patent applications related to other technologies, such as our DBS outdoor unit solutions, to third-parties on reasonable and non-discriminatory terms, we believe that such licensees would need to overcome significant engineering
challenges and develop or obtain comparable proprietary know-how and techniques in order to design products that compete successfully against ours.

|Item 1A. | Risk Factors
|-------- | ------------

Investing in our common stock involves a high degree of risk. Before deciding to purchase, hold or sell our common stock, you should carefully
consider the following information, the other information in this Annual Report and in our other filings with the SEC. If any of these risks were to occur, our business, financial condition, results of operations or prospects could be materially and
adversely affected. In that event, the trading price of our common stock could decline, and you could lose all or part of your investment. The risks and uncertainties described below are not the only ones we face. Additional risks and uncertainties
not presently known to us or that we currently deem immaterial may also affect our business.

Risks Related to Our Business

We have had net operating losses for most of the time we have been in existence, had an accumulated deficit of $177.2 million as of
December 31, 2010 and only recently became profitable on an annual basis, and we are unable to predict whether we will remain profitable.

We were incorporated in 2001, did not commence shipping production quantities of our home networking products until December 2004 and only recently became profitable on an annual basis. Consequently, any
predictions about future performance may not be as accurate as they could be if we had a longer history of successfully commercializing our home networking solutions and profitable operations. You should not rely on our operating results for any
prior quarterly or annual periods as an indication of our future operating performance.

For the year ended December 31, 2010,
we incurred net income of $64.7 million. For the years ended December 31, 2009 and 2008, we incurred net losses of $13.2 million and $136.4 million, respectively. Although we became profitable on an annual basis in 2010, we have incurred
substantial net losses since our inception and, as of December 31, 2010, we had an accumulated deficit of $177.2 million. We may incur operating losses in the future as we continue to make significant expenditures related to the
development of our products and the expansion of our business. Our ability to sustain profitability depends on the extent to which we can maintain or increase revenue and control our costs in order to, among other things, counter any unforeseen
difficulties, complications, product delays or other unknown factors that may require additional expenditures, or unforeseen difficulties or costs associated with the integration of acquired assets or businesses. Because of the numerous risks and
uncertainties associated with our growth prospects, product development, sales and marketing and other efforts, we are unable to predict the extent of our profitability or future losses. If we are unable to achieve adequate growth, we may not
sustain profitability.

We face intense competition and expect competition to increase in the future, with many of our competitors being larger,
more established and better capitalized than we are.

The markets for our products are extremely competitive and have been
characterized by rapid technological change, evolving industry standards, rapid changes in customer requirements, short product life cycles and frequent introduction of next generation and new products, as well as competing technologies. This
competition could make it more difficult for us to sell our products and result in increased pricing pressure, reduced gross profit as a percentage of revenues or gross margins, increased sales and marketing expenses and failure to increase or the
loss of market share or expected market share. Semiconductor products in particular have a history of declining prices driven by customer insistence on lower prices as the cost of production is reduced and as demand falls when competitive products
or newer, more advanced products are introduced. If market prices decrease faster than product costs, our gross margins and operating margins would be adversely affected. Moreover, we expect increased competition from other established and emerging
companies both domestically and internationally. In particular, we currently face, or in the future expect to face, competition from companies such as Broadcom, STMicroelectronics N.V., Trident

Microsystems, Inc., Sigma Designs, Inc., Cisco, Intel Corporation and Vixs Systems, Inc. in the sale of MoCA-compliant chipsets and technology. For example, Broadcom has announced the
availability of several multi-format video decoder system-on-a-chip solutions with integrated MoCA functionality. Broadcoms MoCA home networking reference design platform, which is based on Broadcoms MoCA-enabled system-on-a-chip
product, has achieved MoCA 1.0 and MoCA 1.1 certification from the MoCA certification board. In addition, current and potential competitors may establish cooperative relationships among themselves or with third parties. If so, competitors or
alliances that include our competitors may emerge and could acquire significant market share. Further, our current and potential competitors may also enter into licensing arrangements with third parties with respect to MoCA chipsets or technology on
licensing terms that are more favorable than the licensing terms that we would be able to offer through the direct licensing of our MoCA chipsets and technology to such third parties. We expect these trends to continue as companies attempt to
strengthen or maintain their market positions in an evolving industry. In addition, our competitors could develop products or technologies that cause our products and technologies to become non-competitive or obsolete, or cause us to substantially
reduce our prices.

Currently, we face competition from a number of established companies that offer products based on competing
technologies, such as Data over Cable Service Interface Specifications, versions of Digital Subscriber Line, Ethernet, HomePNA, HomePlug AV, Broadband over Power Line, High Performance Network Over Coax, or HiNOC, Wi-Fi and WiMAX. Although some of
these competing technologies were not originally designed to operate over coaxial cables, our competitors have modified certain technologies, including HomePNA, HomePlug AV, Broadband over Power Line and Wi-Fi, to work on the same in-home coaxial
cables that our MoCA-based products use. We also expect to face competition from companies that offer products based on G.hn technology in the future. Many of our competitors and potential competitors are substantially larger and have longer
operating histories, larger customer bases and significantly greater financial, technical, sales, marketing and other resources than we do. Given their capital resources, many of these larger organizations are in a better position to withstand any
significant reduction in customer purchases or market downturns. Many of our competitors also have broader product lines and market focus, allowing them to bundle their products and services and effectively use other products to subsidize lower
prices for those products that compete with ours or to provide integrated product solutions that offer cost advantages to their customers. In addition, many of our competitors have been in operation much longer than we have and therefore have better
name recognition and more long-standing and established relationships with service providers, ODMs and OEMs.

Our ability to compete
depends on a number of factors, including:



| |  |  | the adoption of our products and technologies by service providers, ODMs and OEMs;
| | - |  | ----------------------------------------------------------------------------------



| |  |  | the performance and cost effectiveness of our products relative to our competitors products;
| | - |  | ---------------------------------------------------------------------------------------------



| |  |  | our ability to deliver high quality and reliable products in large volumes and on a timely basis;
| | - |  | -------------------------------------------------------------------------------------------------



| |  |  | our ability to build close relationships with service providers, ODMs and OEMs;
| | - |  | -------------------------------------------------------------------------------



| |  |  | our success in developing and utilizing new technologies to offer products and features previously not available in the marketplace that are technologically
superior to those offered by our competitors;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our ability to identify new and emerging markets and market trends;
| | - |  | -------------------------------------------------------------------



| |  |  | our ability to reduce our product costs and receive favorable pricing from our suppliers;
| | - |  | -----------------------------------------------------------------------------------------



| |  |  | our ability to recruit design and application engineers and other technical personnel; and
| | - |  | ------------------------------------------------------------------------------------------



| |  |  | our ability to protect our intellectual property and obtain licenses to the intellectual property of others on commercially reasonable terms.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------

Our inability to address any of these factors effectively, alone or in combination with others, could
seriously harm our business, operating results and financial condition.

In addition, consolidation by industry participants could
result in competitors with further increased market share, larger customer bases, greater diversified product offerings and greater technological and marketing expertise, which would allow them to compete more effectively against us. Current and
potential competitors may also gain such competitive advantages by establishing financial or strategic relationships with existing or potential customers, suppliers or other third-parties. These new competitors or alliances among competitors,
customers, or suppliers could emerge rapidly and acquire significant market share. In addition, some of our suppliers and customers offer, or may in the future offer, products that compete with our products. Depending on the participants, industry
consolidation or the formation of strategic relationships could have a material adverse effect on our business and results of operations by reducing our ability to compete successfully in our current markets and the markets we are seeking to serve.

We depend on a limited number of customers, and ultimately service providers, for a substantial portion of our revenues, and the loss of, or a
significant shortfall in, orders from any of these parties could significantly impair our financial condition and results of operations.

We derive a substantial portion of our revenues from a limited number of customers. For example, for the year ended December 31, 2010, Wistron and Motorola accounted for 21% and 17% of our net revenues,
respectively; for the year ended December 31, 2009, Actiontec and Motorola accounted for 16% and 27% of our net revenues, respectively; and for the year ended December 31, 2008, Actiontec and Motorola accounted for 20% and 36% of
our net revenues, respectively. Our inability to generate anticipated revenues from our key existing or targeted customers, or a significant shortfall in sales to certain of these customers would significantly reduce our revenues and adversely
affect our operating results. Our operating results in the foreseeable future will continue to depend on our ability to effect sales to existing and other large customers.

In addition, we depend on a limited number of service providers that purchase products from our customers that incorporate our home networking or digital broadcast satellite outdoor unit solutions. If these service
providers, or other service providers that elect to use our products, reduce or eliminate purchases of our customers products which incorporate our products, this would significantly reduce our revenues and adversely affect our operating
results. In addition, any sudden or unexpected slowdown in deployments by service providers that incorporate our products may lead to an inventory buildup by our customers who may, in turn, postpone taking delivery of our products or wait to clear
their existing inventory before ordering more products from us, which, in turn, may adversely affect our results. Our operating results for the foreseeable future will continue to depend on a limited number of service providers demand for
products which incorporate our products.

We may have conflicts with our customers or the service providers that purchase products from
our customers that incorporate our products. Any such conflict could result in events that have a negative impact on our business, including:



| |  |  | reduced purchases of our products or our customers products that incorporate them;
| | - |  | -----------------------------------------------------------------------------------



| |  |  | uncertainty regarding ownership of intellectual property rights;
| | - |  | ----------------------------------------------------------------



| |  |  | litigation or the threat of litigation; or
| | - |  | ------------------------------------------



| |  |  | settlements or other business arrangements imposing obligations on us or restrictions on our business, including obligations to license intellectual property
rights or make cash payments.

If we fail to develop and introduce new or enhanced products on a timely basis, our ability to attract and
retain customers could be impaired, and our competitive position may be harmed.

To compete successfully, we must design,
develop, market and sell new or enhanced products that provide increasingly higher levels of performance and reliability and meet the cost expectations of our customers. The introduction of new products by our competitors, the market acceptance of
products based on new or alternative technologies, or the emergence of new industry standards could render our existing or future products obsolete. Our failure to anticipate or timely develop new or enhanced products or technologies in response to
technological shifts could result in decreased revenues and an increase in design wins by our competitors. In particular, we may experience difficulties with product design, manufacturing, marketing or certification that could delay or prevent our
development, introduction or marketing of new or enhanced products. If we fail to introduce new or enhanced products that meet the needs of our customers or penetrate new markets in a timely fashion, we may lose market share and our operating
results will be adversely affected. In addition, a design loss to one of our competitors may negatively impact our financial results for several years.

Our results could be adversely affected if our customers or the service providers who purchase their products are unable to successfully compete in their
respective markets.

Our customers and the service providers that purchase products from our customers face significant
competition from their competitors. We rely on these customers and service providers ability to develop products and/or services that meet the needs of their customers in terms of functionality, performance, availability and price. If
these customers and service providers do not successfully compete, they may lose market share, which would negatively impact the demand for our products. For example, for our home networking products, there is intense competition among service
providers to deliver video and other multimedia content into and throughout the home. For the sale of our home networking products, we are currently dependent on the ability of a limited number of service providers to compete in the market for the
delivery of HD video and other multimedia content. Therefore, factors influencing the ability of these service providers to compete in this market, such as competition from alternative content providers or laws and regulations regarding local cable
franchising or satellite broadcasting rights, could have an adverse effect on our ability to sell home networking products. In addition, our digital broadcast satellite outdoor unit products are primarily supplied to digital broadcast satellite
service providers by our ODM and OEM customers. Digital broadcast satellite service providers are facing significant competition from telecommunications carriers and cable service operators as they compete for customers in terms of video, voice and
data services. Moreover, ODMs and OEMs who market satellite set-top boxes using our silicon tuners are competing with a variety of Internet protocol-based video delivery solutions, including versions of Digital Subscriber Line technology and certain
fiber optic-based solutions. Many of these technologies compete effectively with satellite set-top boxes and do not require tuners such as the ones we sell. If our customers and the service providers who purchase products from our customers that
incorporate our products do not successfully compete, they may lose market share, which would reduce demand for our products.

If the market for
HD video and other multimedia content delivery solutions based on the MoCA standard does not develop as we anticipate, our revenues may decline or fail to grow, which would adversely affect our operating results.

We derive, and expect to continue to derive for the foreseeable future, a significant portion of our revenues from sales of our home networking
products based on the MoCA standard. The market for multimedia content delivery solutions based on the MoCA standard is relatively new, still evolving and difficult to predict. Currently, the growth of the MoCA-based multimedia content delivery
market and the success of our business are largely driven by the adoption and deployment of existing and future generations of the technology by service providers, ODMs and OEMs and, to a lesser extent, by



28

##### Table of Contents

consumer adoption of such technology which is dependent on the availability of OTT services that directly deliver Internet video content into the home. It is uncertain whether the MoCA standard
will achieve and sustain high levels of demand and market acceptance by service providers or consumers, whether the availability of OTT services will continue to grow or whether consumers beyond the early technology adopters will embrace OTT
services in increasing numbers, if at all.

Some service providers, ODMs and OEMs have adopted, and others may adopt, multimedia content
delivery solutions that rely on technologies other than the MoCA standard or may choose to wait for the introduction of products and technologies that serve as a replacement or substitute for, or represent an improvement over, MoCA-based solutions.
The alternative technology solutions, which compete with MoCA-based solutions, include Ethernet, HomePNA, Home Plug AV, G.hn, Wi-Fi and WiMedia. It is critical to our success that additional service providers, including telecommunications carriers,
digital broadcast satellite service providers and cable operators, adopt the MoCA standard for home networking. If the market for MoCA-based solutions does not continue to develop or develops more slowly than we expect, or if we make errors in
predicting adoption and deployment rates for these solutions, our revenues may be significantly adversely affected. Our operating results may also be adversely affected by any delays in consumer adoption of OTT services, or if the market for OTT
services develops more slowly than we expect.

Even if service providers, ODMs and OEMs adopt multimedia content delivery solutions based on the
MoCA standard, we may not compete successfully in the market for MoCA-compliant chipsets.

As a member of MoCA, we are required
to license any of our patent claims that are essential to implement the MoCA specifications to other MoCA members on reasonable and non-discriminatory terms. As a result, we are required to license some of our important intellectual property to
other MoCA members, including other semiconductor manufacturers that may compete with us in the sale of MoCA-compliant chipsets. Furthermore, there may be disagreements among MoCA members as to specifically which of our patent claims we are required
to license to them. If we are unable to differentiate our MoCA-compliant chipsets from other MoCA-compliant chipsets by offering superior pricing and features outside MoCA specifications, we may not be able to compete effectively in the market for
such chipsets. Moreover, although we are currently and actively involved in the ongoing development of the MoCA standard, we cannot guarantee that future MoCA specifications will incorporate technologies or product features we are developing or that
our products will be compatible with future MoCA specifications. As additional members, including our competitors, continue to join MoCA, they and existing members may exert greater influence on MoCA and the development of the MoCA standard in a
manner that is adverse to our interests. If our home networking products fail to comply with future MoCA specifications, the demand for these products could be severely reduced.

The semiconductor and communications industries are highly cyclical and subject to rapid change and evolving industry standards and, from time to time, have experienced significant downturns in customer
demand as well as unexpected increases in demand resulting in production capacity constraints. These factors could impact our operating results, financial condition and cash flows and may increase the volatility of the price of our common stock.

The semiconductor and communications industries are highly cyclical and subject to rapid change and evolving industry standards
and, from time to time, have experienced significant downturns in customer demand, most recently in late 2008 through 2009 as a result of the deterioration in global macroeconomic conditions. These downturns are characterized by decreases in product
demand, excess customer inventories and accelerated erosion of prices; factors which have caused, and could continue to cause, substantial fluctuations in our net revenue and in our



29

##### Table of Contents

operating results. Any downturns in the semiconductor and communications industries may be severe and prolonged, and any failure of these industries to fully recover from downturns could harm our
business. For example, because a significant portion of our expense is fixed in the near term or is incurred in advance of anticipated sales, during these downturns we may not be able to decrease our expenses rapidly enough to offset unanticipated
shortfalls in revenues during industry downturns, which would adversely affect our operating results. Even as the industry recovers from the most recent downturn, some OEMs and ODMs may continue to slow down their research and development
activities, cancel or delay new product development, reduce their inventories and/or take a cautious approach to acquiring products, which may negatively impact our business.

The semiconductor and communications industries also periodically experience increased demand and production capacity constraints, which may affect the ability of companies such as ours to ship products to
customers. Any factor adversely affecting either the semiconductor or communications industries in general, or the particular segments of any of these industries that our products target, may adversely affect our ability to generate revenue and
could negatively impact our operating results, cash flow and financial condition. During 2010, the semiconductor and communications industries began experiencing supply shortages due to sudden increases in demand beyond foundry capacity. In addition
to capacity issues, during periods of increased demand these industries may also experience difficulty obtaining sufficient manufacturing, assembly and test resources from manufacturers. If, as a result of these industry issues, we are unable to
meet our customers increased demand for our products, we would miss opportunities for additional revenue and could experience a negative impact on our relationships with affected customers. Further, in response to the cyclical and rapidly
changing nature of the semiconductor and communications industries, our operating results may fluctuate from period to period as we adjust our inventory and production requirements to meet the changing demands of our customers, which could impact
our financial condition and cash flows and may increase the volatility of the price of our common stock.

Our operating results have fluctuated
significantly in the past and we expect them to continue to fluctuate in the future, which could lead to volatility in the price of our common stock.

Our operating results have fluctuated in the past and are likely to continue to fluctuate, on an annual and a quarterly basis, as a result of a number of factors, many of which are outside of our control. These
fluctuations in our operating results may cause our stock price to fluctuate as well. The primary factors that are likely to affect our quarterly and annual operating results include:



| |  |  | changes in demand for our products or those offered by service providers and our customers;
| | - |  | -------------------------------------------------------------------------------------------



| |  |  | the timing and amount of orders, especially from significant service providers and customers;
| | - |  | ---------------------------------------------------------------------------------------------



| |  |  | the seasonal nature of the sales of products that incorporate our products by certain service providers which may affect the timing of orders for our products;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the level and timing of capital spending of service providers, both in the United States and in international markets;
| | - |  | ----------------------------------------------------------------------------------------------------------------------

| |  |  | costs associated with litigation; and
| | - |  | -------------------------------------



| |  |  | changes in domestic and international regulatory environments.
| | - |  | --------------------------------------------------------------

Unfavorable changes in any of the above factors, many of which are beyond our control, could significantly harm our business and results of operations. You should not rely on the results of prior periods as an
indication of our future performance.

Adverse U.S. and international economic conditions have affected and may continue to adversely affect our
revenues, margins and profitability.

Since September 2008, the credit markets and the financial services industry have been
experiencing a period of unprecedented turmoil and upheaval characterized by the bankruptcy, failure, collapse or sale of various financial institutions and an unprecedented level of intervention from the U.S. federal government. These events,
together with the recent adverse economic conditions facing the broader economy and, in particular, the semiconductor and communications industries, have adversely affected, and may continue to adversely affect, our business as service providers cut
back or delay deployments that include our products and to the extent that consumers decrease their discretionary spending for enhanced video offerings from service providers, which may in turn lead to cautious or reduced spending by service
providers and, in turn, may lead to a decrease in orders for our products, thereby adversely affecting our operating results. Our operating results may also be adversely affected if the State of California adopts laws to suspend net operating loss
deductions as it has done in the past in response to the sharp decrease in tax revenue collections caused by the current adverse economic conditions.

We may also experience adverse conditions in our cost base due to changes in foreign currency exchange rates that reduce the purchasing power of the U.S. dollar, increase research and development expenses and
otherwise harm our business. These conditions may harm our margins

and prevent us from sustaining profitability if we are unable to increase the selling prices of our products or reduce our costs sufficiently to offset the effects of effective increases in our
costs. Our attempts to offset the effects of cost increases through controlling our expenses, passing cost increases on to our customers or any other method may not succeed.

The success of our digital broadcast satellite outdoor unit products depends on the demand for our products within the satellite digital television market and the growth of this overall market.

In addition to our MoCA home networking products, we also derive a significant portion of our revenues from sales of our digital
broadcast satellite outdoor unit products into markets served by digital broadcast satellite providers and their ODM and OEM partners. The digital broadcast satellite market may not grow in the future as anticipated or a significant market slowdown
may occur, which would in turn reduce the demand for applications or devices, such as set-top boxes and low-noise block converters that rely on our digital broadcast satellite outdoor unit products. Because of the intense competition in the
satellite, terrestrial and cable digital television markets, the unproven technology of many products addressing these markets and the short product life cycles of many consumer applications or devices, it is difficult to predict the potential size
and future growth rate of the markets for our digital broadcast satellite outdoor unit products. If the demand for our digital broadcast satellite outdoor unit products is not as great as we expect, or if we are unable to produce competitive
products to meet that demand, our revenues could be adversely affected.

Market-specific risks affecting the digital television, digital
television set-top boxes and digital television peripheral markets could impair our ability to successfully sell our silicon tuners.

The market for digital television applications in digital televisions, digital television set-top boxes and digital television peripherals is characterized by certain market-specific risks, any of which may
adversely affect our ability to sell our silicon tuners. For example, sellers of module tuners that offer similar or better functionality than our silicon tuner solutions may dramatically lower their prices and become more competitive than we are in
the tuner market. In addition, our silicon tuners may not meet the specifications or have the feature sets desired by our customers or may not be architecturally compatible with other components in the customers designs. Our efforts to
penetrate the digital television market, in particular, will depend on our ability to overcome these and other challenges. To the extent our efforts are adversely affected by any of these risks or are otherwise unsuccessful, the demand for our
silicon tuner products may not develop as anticipated or decline which would adversely affect our revenues, financial condition and results of operations.

The success of our silicon tuners is highly dependent on our relationships with demodulator manufacturers.

Our silicon tuners are designed to be interoperable with various specific demodulator integrated circuit products that are designed and manufactured by other companies. Historically, we have relied on strategic
relationships with various demodulator manufacturers to enable both parties to offer an interoperable tuner/demodulator solution to mutual end customers. Although we work in concert with third-party demodulator manufacturers to complete highly
functional reference designs, we have no control over their future product plans and product roadmaps and could be effectively designed out of future customer applications by the refusal of a demodulator manufacturer to continue to support our
products. Likewise, our ability to acquire new customers is dependent on the cooperation of third-party demodulator manufacturers. If such third-party manufacturers decide to partner with one of our competitors or to provide their own tuner
solutions, we would effectively be prevented from selling our products to potential new customers. Furthermore, our dependence on these third-party demodulator manufacturers often limits our strategic direction. If we were to design products that
were competitive with any of such demodulator manufacturers, they may choose to stop working with us.

##### Table of Contents

If any of the current or prospective demodulator manufacturers with whom we have or intend to have
relationships with were to stop working with us in favor of other tuner manufacturers or in favor of deploying their own tuner products, we would be effectively designed out of current and potential customers products and the demand for our
silicon tuners would be substantially reduced.

The market for our broadband access products is limited and these products may not be widely
adopted.

Our broadband access products are designed to meet broadband access requirements in areas characterized by fiber optic
network deployments that terminate within one kilometer of customer premises. We believe the primary geographic markets for our broadband access products are currently in certain Asian countries such as China, Japan, Korea, and parts of Europe where
there are many multi-dwelling units and fiber optic networks that extend to or near a customer premises. We do not expect to generate significant revenues from sales of our broadband access products in North America, which is generally characterized
by low-density housing, or in developing nations which do not generally have extensive fiber optic networks. To the extent our efforts to sell our broadband access products into currently targeted markets are unsuccessful, the demand for these
products may not develop as anticipated or may decline, either of which could adversely affect our future revenues. Moreover, these markets have a large number of service providers and varying regulatory standards, both of which may delay any
widespread adoption of our products and increase the time during which competing technologies could be introduced and displace our products.

In addition, if areas characterized by fiber optic networks that terminate within one kilometer of customer premises do not continue to grow, or we are unable to develop broadband access products that are
competitive outside of these areas, the demand for our broadband access products may not grow and our revenues may be limited. Even if the markets in which our broadband access products are targeted continue to grow or we are able to serve
additional markets, customers and service providers may not adopt our technology. There are a growing number of competing technologies for delivering high-speed broadband access from the service providers network to the customers
premises. For example, our broadband access products face competition from products using DOCSIS, versions of DSL, Ethernet and WiMAX-based solutions. Moreover, there are many other access technologies that are currently in development including
some low cost proprietary solutions. If service providers adopt competing products or technologies, the demand for our broadband access products will decline and we may not be able to generate significant revenues from these products.

We intend to expand our operations and increase our expenditures in an effort to grow our business. If we are not able to manage this expansion and growth,
or if our business does not grow as we expect, we may not be able to realize a return on the resources we devote to expansion.

We anticipate that we will continue to expand our infrastructure and grow our headcount to accommodate changes in our research and development
strategy and achieve planned expansion of our product offerings, projected increases in our customer base and anticipated growth in the number of our product deployments. Our growth may place a strain on our administrative and operational
infrastructure. Our success in managing our growth will be dependent upon our ability to:



| |  |  | enhance our operational, financial and management controls, reporting systems and procedures;
| | - |  | ---------------------------------------------------------------------------------------------



| |  |  | expand our facilities and equipment and develop new sources of supply for the manufacture, assembly and testing of our semiconductor products;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------

| |  |  | successfully hire, train, motivate and productively deploy additional employees, including technical personnel; and
| | - |  | -------------------------------------------------------------------------------------------------------------------



| |  |  | expand our international resources.
| | - |  | -----------------------------------

Our inability to address effectively any of these factors, alone or in combination with others, could harm our ability to execute our business strategy.

Further, we intend to continue to grow our business by entering new markets, developing new product offerings and pursuing new customers. If we
fail to timely or efficiently expand operational and financial systems in connection with such growth or if we fail to implement or maintain effective internal controls and procedures, resulting operating inefficiencies could increase costs and
expenses more than we planned and might cause us to lose the ability to take advantage of market opportunities, enhance existing products, develop new products, satisfy customer requirements, respond to competitive pressures, control our inventory
or otherwise execute our business plan. Failure to implement or maintain such controls and procedures could also impact our ability to produce timely and accurate financial statements. Additionally, if we increase our operating expenses in
anticipation of the growth of our business and such growth does not meet our expectations, our financial results likely would be negatively impacted.

Any acquisition, strategic relationship, joint venture or investment could disrupt our business and harm our financial condition.

We actively pursue acquisitions, strategic relationships, joint ventures, collaborations and investments that we believe may allow us to complement
our growth strategy, increase market share in our current markets or expand into adjacent markets, or broaden our technology and intellectual property. Such transactions may be complex, time consuming and expensive, and may present numerous
challenges and risks including:



| |  |  | difficulties in assimilating any acquired workforce and merging operations;
| | - |  | ---------------------------------------------------------------------------



| |  |  | attrition and the loss of key personnel;
| | - |  | ----------------------------------------



| |  |  | an acquired company, asset or technology, or a strategic collaboration or licensed asset or technology not furthering our business strategy as anticipated;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our overpayment for a company, asset or technology or changes in the economic or market conditions or assumptions underlying our decision to make an acquisition;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | difficulties entering and competing in new product or geographic markets and increased competition, including price competition;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------



| |  |  | significant problems or liabilities, including increased intellectual property and employment related litigation exposure, associated with acquired businesses,
assets or technologies;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | in connection with any such transaction, the need to use a significant portion of our available cash, issue additional equity securities that would dilute the
then-current stockholders percentage ownership or incur substantial debt or contingent liabilities;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | requirements to devote substantial managerial and engineering resources to any strategic relationship, joint venture or collaboration, which could detract from
our other efforts or significantly increase our costs;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | lack of control over the actions of our business partners in any strategic relationship, joint venture or collaboration, which could significantly delay the
introduction of planned products or otherwise make it difficult or impossible to realize the expected benefits of such relationship; and
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | requirements to record substantial charges and amortization expense related to certain intangible assets, deferred stock compensation and other items.

Any one of these challenges or risks could impair our ability to realize any benefit from our
acquisitions, strategic relationships, joint ventures or investments after we have expended resources on them.

In addition, from time
to time we may enter into negotiations for acquisitions, relationships, joint ventures or investments that are not ultimately consummated. These negotiations could result in significant diversion of our managements time, as well as substantial
out-of-pocket costs.

We cannot forecast the number, timing or size of future acquisitions, strategic relationships, joint ventures or
investments, or the effect that any such transactions might have on our operating or financial results. Any such transaction could disrupt our business and harm our operating results and financial condition.

We may not realize the anticipated financial and strategic benefits from the businesses we have acquired or be able to successfully integrate such businesses
with ours.

We will need to overcome significant challenges in order to realize the benefits or synergies from the acquisitions
we have completed to date and any acquisitions that we may complete from time to time in the future. These challenges include the following:



| |  |  | integrating businesses, operations and technologies;
| | - |  | ----------------------------------------------------



| |  |  | retaining and assimilating key personnel;
| | - |  | -----------------------------------------



| |  |  | retaining existing customers and attracting additional customers;
| | - |  | -----------------------------------------------------------------



| |  |  | creating uniform standards, controls, procedures, policies and information systems;
| | - |  | -----------------------------------------------------------------------------------



| |  |  | meeting the challenges inherent in efficiently managing an increased number of employees, including some at geographic locations distant from our headquarters
and senior management; and
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | implementing appropriate systems, policies, benefits and compliance programs.
| | - |  | -----------------------------------------------------------------------------

Integration in particular may involve considerable risks and may not be successful. These risks include the following:



| |  |  | the potential disruption of our ongoing business and distraction of our management;
| | - |  | -----------------------------------------------------------------------------------



| |  |  | the potential strain on our financial and managerial controls and reporting systems and procedures;
| | - |  | ---------------------------------------------------------------------------------------------------



| |  |  | unanticipated expenses and potential delays related to integration of the operations, technology and other resources of the acquired companies;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the impairment of relationships with employees, suppliers and customers; and
| | - |  | ----------------------------------------------------------------------------



| |  |  | potential unknown or contingent liabilities.
| | - |  | --------------------------------------------

The inability to integrate successfully any businesses we acquire, or any significant delay in achieving integration, could delay introduction of new products and require expenditure of additional resources to
achieve integration. For example, although we recorded significant amounts of goodwill and other intangible assets in connection with the acquisitions we completed in 2007 and 2008, as a result of the recent industry and economic turmoil and its
effects on our market value and business outlook, we had to reduce the carrying amount of all of these long-lived assets and, as of December 31, 2010, we had recorded an aggregate impairment charge of $113.4 million against our goodwill
and intangible assets carrying value related to these acquisitions.

Investors should not rely on attempts to combine our historical financial results with those of any of
our acquired businesses as separate operating entities to predict our future results of operations as a combined entity.

The average selling
prices of our products have historically decreased over time and will likely do so in the future, which may reduce our revenues and gross margin.

Our products and products sold by other companies in our industry have historically experienced a decrease in average selling prices over time. We anticipate that the average selling prices of our products will
continue to decrease in the future in response to competitive pricing pressures, increased sales discounts and new product introductions by our competitors. For example, we expect that other chipset manufacturers who are members of MoCA will produce
competing chipsets and create pricing pressure for such products and Broadcom has announced the availability of competing chipsets for certain applications. Our future operating results may be harmed due to the decrease of our average selling
prices. To maintain our current gross margins or increase our gross margins in the future, we must develop and introduce on a timely basis new products and product enhancements, continually reduce our product costs and manage product transitions in
a timely and cost-effective manner. Our failure to do so would likely cause our revenues and gross margins to decline, which could have a material adverse effect on our operating results and cause the value of our common stock to decline.

Fluctuations in the mix of products we sell may adversely affect our financial results.

Because of differences in selling prices and manufacturing costs among our products, the mix and types of products sold affect the average selling
price of our products and have a substantial impact on our revenues and profit margins. To the extent our sales mix shifts toward increased sales of our lower-margin products, our overall gross margins will be negatively affected. Fluctuations in
the mix and types of our products sold may also affect the extent to which we are able to recover our costs and expenditures that are associated with a particular product, and as a result, can negatively impact our financial results.

Our product development efforts are time-consuming, require substantial research and development expenditures and may not generate an acceptable return.

Our product development efforts require substantial research and development expense. Our research and development expense was
$48.7 million and $45.2 million for the year ended December 31, 2010 and 2009, respectively. There can be no assurance that we will achieve an acceptable return on our research and development efforts.

The development of our products is also highly complex. Due to the relatively small size of our product design teams, our research and development
efforts in our core technologies may lag behind those of our competitors, some of whom have substantially greater financial and technical resources. In the past, we have occasionally experienced delays in completing the development and introduction
of new products and product enhancements, and we could experience delays in the future. Unanticipated problems in developing products could also divert substantial engineering resources, which may impair our ability to develop new products and
enhancements and could substantially increase our costs. Furthermore, we may expend significant amounts on a research and development program that may not ultimately result in a commercially successful product, and we have in the past terminated
ongoing research and development programs before they could be brought to successful conclusions. As a result of these and other factors, we may be unable to develop and introduce new products successfully and in a cost-effective and timely manner,
and any new products we develop and offer may never achieve market acceptance. Any failure to develop future products that are commercially successful would have a material adverse effect on our business, financial condition and results of
operations.

Our products typically have lengthy sales cycles, which may cause our operating results to fluctuate, and a
service provider, ODM or OEM customer may decide to cancel or change its service or product plans, which could cause us to lose anticipated sales.

Our products typically have lengthy sales cycles. A service provider must first evaluate our products. This initial evaluation period can vary considerably based on the service provider and product being evaluated,
and could take a significant amount of time to complete. Products incorporating new technologies generally require longer periods for evaluation. After this initial evaluation period, if a service provider decides to adopt our products, that service
provider and the applicable ODM or OEM customers will need to further test and evaluate our products prior to completing the design of the equipment that will incorporate our products. Additional time is needed to begin volume production of
equipment that incorporates our products. Due to these lengthy sales cycles, we may experience significant delays from the time we incur research and development and sales expenses until the time, if ever, that we generate sales from these products.
The delays inherent in these lengthy sales cycles increase the risk that a customer will decide to cancel or change its product plans. From time to time, we have experienced changes, delays and cancellations in the purchase plans of our customers. A
cancellation or change in plans by a service provider, ODM or OEM customer could prevent us from realizing anticipated sales. In addition, our anticipated sales could be lost or substantially reduced if a significant service provider, ODM or OEM
customer reduces or delays orders during our sales cycle or chooses not to release equipment that contains our products. We may invest significant time and effort in marketing to a particular customer that does not ultimately result in a sale to
that customer. As a result of these lengthy and uncertain sales cycles for our products, it is difficult for us to predict if or when our customers may purchase products in volume from us, and our operating results may vary significantly from
quarter to quarter, which may negatively affect our operating results for any given quarter.

If we do not complete our design-in activities
before a customers design window closes, we will lose the design opportunity, which could adversely affect our future sales and revenues and harm our customer relationships.

The timing of our design-in activities with key customers and prospective customers may not align with their open design windows, which may or may
not be known to us, making design win predictions more difficult. If we miss a particular customers design window, we may be forced to wait an entire year or even longer for the next opportunity to compete for the customers next design.
The loss of a particular design opportunity could eliminate or substantially delay revenues from certain target customers and markets, which could have a material adverse effect on our results of operations and future prospects as well as our
customer relationships.

Our products must interoperate with many software applications and hardware found in service providers networks and
other devices in the home, and if they do not interoperate properly our business would be harmed.

Our products must interoperate
with service providers networks and other devices in the home, which often have varied and complex specifications, utilize multiple protocol standards, software applications and products from multiple vendors, and contain multiple generations
of products that have been added over time. As a result, we must continually ensure that our products interoperate properly with existing and planned future networks. To meet these requirements, we must undertake development efforts that involve
significant expense and the dedication of substantial employee resources. We may not accomplish these development efforts quickly or cost-effectively, if at all. If we fail to maintain or anticipate compatibility with products, software or equipment
found in our customers networks, we may face substantially reduced demand for our products, which would adversely affect our business, operating results and financial condition.

From time to time, we may enter into collaborations or interoperability arrangements with equipment
and software vendors providing for the use, integration or interoperability of their technology with our products. These arrangements would give us access to and enable interoperability with various products or technologies in the connected home
entertainment market. If these relationships fail to achieve their goals, we would have to devote substantially more resources to the development of alternative products and the support of our existing products, or the addressable market for our
products may become limited. In many cases, these parties are either companies that we compete with directly in other areas or companies that have extensive relationships with our existing and potential customers and may have influence over the
purchasing decisions of these customers. A number of our competitors have stronger relationships than we do with some of our existing and potential customers and, as a result, our ability to have successful arrangements with these companies may be
harmed. Our failure to establish or maintain key relationships with third-party equipment and software vendors may harm our ability to successfully sell and market our products. We are currently devoting significant resources to the development of
these relationships. Our operating results could be adversely affected if these efforts do not result in the revenues necessary to offset these investments.

In addition, if we find errors in the software or hardware used in service providers networks or problematic network configurations or settings we may have to modify our products so that they will
interoperate with these networks. This could cause longer installation times for our products and order cancellations, either of which would adversely affect our business, operating results and financial condition.

Our customers may cancel their orders, change production quantities or delay production, and if we fail to forecast demand for our products accurately, we
may incur product shortages, delays in product shipments or excess or insufficient product inventory.

We sell our products to
customers who integrate them into their products. We do not obtain firm, long-term purchase commitments from our customers. We have limited visibility as to the volume of our products that our customers are selling or carrying in their inventory. In
addition, certain service providers are affected by seasonality in their deployment of products that incorporate our products, which may in turn impact the timing of our sales. Because production lead times often exceed the amount of time required
to fulfill orders, we often must build inventory in advance of orders, relying on an imperfect demand forecast to project volumes and product mix. Our demand forecast accuracy, and our ability to manage our inventory carrying levels accurately, can
be adversely affected by a number of factors, including inaccurate forecasting by our customers, changes in market conditions, adverse changes in our product order mix and demand for our customers products. We have in the past had customers
dramatically decrease and increase their requested production quantities with little or no advance notice to us. Even after an order is received, our customers may cancel these orders, postpone taking delivery or request a decrease in production
quantities. Any such cancellation, postponement of delivery or decrease in production quantity subjects us to a number of risks, most notably that our projected sales will not materialize on schedule or at all, leading to unanticipated revenue
shortfalls, reduced profit margins and excess or obsolete inventory which we may be unable to sell to other customers or which we may be required to sell at reduced prices or write off entirely. Furthermore, changes to our customers
requirements may result in disputes with our customers which could adversely impact our future relationships with those customers. Alternatively, if we are unable to project customer requirements accurately, we may not build enough products, which
could lead to delays in product shipments and lost sales opportunities in the near term, as well as force our customers to identify alternative sources of supply, which could affect our ongoing relationships with these customers and potentially
reduce our market share. If we do not timely fulfill customer demands, our customers may cancel their orders and we may be subject to customer claims for cost of replacement.

Our ability to accurately predict revenues and inventory needs, and to effectively manage inventory levels, may
be adversely impacted due to our use of inventory hubbing arrangements.

We are party to an inventory
hubbing arrangement with Motorola and we may enter into similar arrangements with other customers in the future. Pursuant to these arrangements, we ship our products to a designated third-party warehouse, or hub, rather than shipping
them directly to the customer. The products generally remain in the hub until the customer removes them for incorporation into its own products. In the absence of any hubbing arrangement, we generally recognize revenues on sales of our products upon
shipment of those products to the buyer. Under our hubbing arrangement with Motorola, however, we maintain ownership of our products in the hub, and therefore do not recognize the related revenue until the date Motorola removes them from the hub. As
a result, our ability to accurately predict future revenues recognized from sales to Motorola or any other customers with which we implement hubbing arrangements may be impaired, and we may experience significant fluctuations in our quarterly
operating results depending on when Motorola or any such other customers remove our products from the hub, which they may do with little or no lead time. In the short term, we may experience an increase in operating expenses as we build and ship
inventory to the hub and will not recognize revenues from sales of this inventory, if at all, until Motorola or any such other customers remove it from the hub at a later time. Furthermore, because we continue to own but do not maintain control over
our products after they are shipped to the hub, our ability to effectively manage inventory levels may be impaired as our shipments under the hubbing arrangement increase and we may be exposed to additional risk that the inventory in the hub becomes
obsolete before sales are recognized.

We extend credit to our customers, sometimes in large amounts, but there is no guarantee every customer
will be able to pay our invoices when they become due.

As part of our routine business, we extend credit to customers purchasing
our products. While our customers may have the ability to pay on the date of shipment or on the date credit is granted, their financial condition could change and there is no guarantee that customers will ever pay the invoices. Rapid changes in our
customers financial conditions and risks associated with extending credit to our customers can subject us to a higher financial risk and could have a material adverse effect on our business, financial condition and results of operations.

We depend on a limited number of third parties to manufacture, assemble and test our products which reduces our control over key aspects of our
products and their availability.

We do not own or operate a manufacturing, assembly or test facility for our products. Rather,
we outsource the manufacture, assembly and testing of our products to third-party subcontractors including TSMC, Jazz Semiconductor, Inc. (a wholly owned subsidiary of Tower Semiconductor, Inc), or TowerJazz, Amkor and Giga Solution. Accordingly, we
are greatly dependent on a limited number of suppliers to deliver quality products on time. Our reliance on sole or limited suppliers involves several risks, including susceptibility to increased manufacturing costs if competition for foundry
capacity intensifies and reduced control over the following:



| |  |  | supply of our products available for sale;
| | - |  | ------------------------------------------



| |  |  | pricing, quality and timely delivery of our products;
| | - |  | -----------------------------------------------------



| |  |  | prices and availability of components for our products; and
| | - |  | -----------------------------------------------------------



| |  |  | production capacity for our products, including shortages due to the difficulties of suppliers to meet production capacities because of unexpected increases in
demand.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------

Because we rely on a limited number of third-party manufacturers, if we were required to change contract
manufacturers or one of our contract manufacturers became unable or unwilling to continue

##### Table of Contents

manufacturing our products, we may sustain lost revenues, increased costs and damage to our customer relationships. In addition, we would need to expend significant time and effort to locate new
third-party manufacturers, if available, and have them qualified by us and our customers.

Manufacturing defects may not be detected by
the testing process performed by our subcontractors. If defects are discovered after we have shipped our products, we may be exposed to warranty and consequential damages claims from our customers. Such claims may have an adverse impact on our
revenues and operating results. Furthermore, if we are unable to deliver quality products, our reputation would be harmed, which could result in the loss of future orders and business with our customers.

When demand for manufacturing capacity is high, we may take various actions to try to secure sufficient capacity, which may be costly and negatively impact
our operating results.

The ability of each of our subcontractors manufacturing facilities to provide us with chipsets is
limited by their available capacity and existing obligations. Although we have purchase order commitments to supply specified levels of products to our customers, we do not have a guaranteed level of production capacity from any of our
subcontractors facilities to produce our products. Facility capacity may not be available when we need it or at reasonable prices. In addition, our subcontractors may allocate capacity to the production of other companies products and
thereby reduce deliveries to us on short notice.

In order to secure sufficient manufacturing facility capacity when demand is high and
mitigate the risks associated with an inability to meet our customers demands for our products, we may enter into various arrangements with subcontractors that could be costly and harm our operating results, including:



| |  |  | option payments or other prepayments to a subcontractor;
| | - |  | --------------------------------------------------------



| |  |  | nonrefundable deposits with or loans to subcontractors in exchange for capacity commitments;
| | - |  | --------------------------------------------------------------------------------------------



| |  |  | contracts that commit us to purchase specified quantities of components over extended periods; and
| | - |  | --------------------------------------------------------------------------------------------------



| |  |  | purchase of testing equipment for specific use at the facilities of our subcontractors.
| | - |  | ---------------------------------------------------------------------------------------

We may not be able to make any such arrangements in a timely fashion or at all, and any arrangements may be costly, reduce our financial
flexibility and not be on terms favorable to us. Moreover, if we are able to secure capacity, we may be obligated to use all of that capacity or incur penalties. These penalties and obligations may be expensive and require significant capital and
could harm our business.

We believe that transitioning certain of our silicon products to newer or better manufacturing process technologies will
be important to our future competitive position. If we fail to make this transition efficiently, our competitive position could be seriously harmed.

We continually evaluate the benefits, on a product-by-product basis, of migrating to higher performance or lower cost process technologies in order to produce higher performance, more efficient or better integrated
circuits because we believe this migration is required to remain competitive. Other companies in our industry have experienced difficulty in migrating to new process technologies and, consequently, have suffered reduced yields, delays in product
deliveries and increased expense levels. We may experience similar difficulties. Moreover, we are dependent on our relationships with subcontractors to successfully migrate to newer or better process technologies.

##### Table of Contents

Our third-party manufacturers may not make newer or better process technologies available to us on a timely or cost-effective basis, if at all. If our third-party manufacturers do not make newer
or better manufacturing process technologies available to us on a timely or cost-effective basis, or if we experience difficulties in migrating to these processes, it could have a material adverse effect on our competitive position and business
prospects.

We rely on sales representatives and distributors to assist in selling our products, and the failure of these representatives to
perform as expected could reduce our future sales.

We sell some of our products through third-party sales representatives and
distributors. Our relationships with some of these third-party sales representatives and distributors are relatively new and we are unable to predict the extent to which our third-party sales representatives and distributors will be successful in
marketing and selling our products. Moreover, many third-party sales representatives and distributors also market and sell competing products. Third-party sales representatives and distributors may terminate their relationships with us at any time,
or with short notice, and may give greater attention to the products sold by our competitors. Our future performance will also depend, in part, on our ability to attract additional third-party sales representatives and distributors that market our
products effectively, especially in markets in which we have not previously distributed our products. If we cannot retain our current third-party sales representatives and distributors and recruit additional or replacement third-party sales
representatives and distributors, our revenues and operating results could be harmed.

Our products may contain defects or errors which may
adversely affect their market acceptance and our reputation and expose us to product liability claims.

Our products are very
complex and may contain defects or errors, especially when first introduced or when new versions are released. Despite testing, errors may occur. Product errors could affect the performance of our products, delay the development or release of new
products or new versions of products, adversely affect our reputation and our customers willingness to buy products from us, and adversely affect market acceptance of our products. Any such errors or delays in releasing new products or new
versions of products or allegations of unsatisfactory performance could cause us to lose revenue or market share, increase our service costs, cause us to incur substantial costs in redesigning our products, subject us to liability for damages and
divert our resources from other tasks. Our products must successfully interoperate with products from other vendors. As a result, when problems occur in a device or application in which our product is used, it may be difficult to identify the
sources of these problems. The occurrence of hardware and software errors, whether or not caused by our products, could result in the delay or loss of market acceptance of our products, and therefore delay our ability to recognize revenue from
sales, and any necessary revisions may cause us to incur significant expenses. Moreover, since one of the key benefits of our home networking products is reduction of the need for truck rolls, problems with our products would likely result in a
greater number of truck rolls and this in turn could adversely affect our sales. The occurrence of any such problems could harm our business, operating results and financial condition.

Any limitation of liability provisions in our standard terms and conditions of sale may not fully or effectively protect us from claims as a result
of federal, state or local laws or ordinances or unfavorable judicial decisions in the United States or other countries. The use of our products also entails the risk of product liability claims. We maintain insurance to protect against certain
claims associated with the use of our products, but our insurance coverage may not adequately cover any claim asserted against us. In addition, even claims that ultimately are unsuccessful could result in our expenditure of funds in litigation and
divert our managements time and other resources.

##### Table of Contents

We depend on key personnel to operate our business, and if we are unable to retain our current personnel and
hire additional qualified personnel, our ability to develop and successfully market our products could be harmed.

We believe our
future success will depend in large part upon our ability to attract and retain highly skilled managerial, engineering and sales and marketing personnel. Even during the recent economic downturn, there continues to be competition for qualified
personnel in the markets in which we compete. In addition, the cost of living in the San Diego, California area, where our corporate headquarters is located, has proved to be an obstacle to attracting new employees in the past, and we expect that
this will continue to impact, to some extent, our ability to attract and retain employees in the future. We do not have employment agreements with most of our executive or key employees and the unexpected loss of any key employees, including Patrick
Henry, our president and chief executive officer, other members of our senior management or our senior engineering personnel, or an inability to attract additional qualified personnel, including engineers and sales and marketing personnel, could
delay the development, introduction and sale of our products and our ability to execute our business strategy may suffer. In addition, in the event that there is a loss of key personnel, there is a potential for loss of important knowledge that may
delay or negatively impact development or sale of our products and our ability to execute on our business strategy. We do not currently have any key person life insurance covering any executive officer or employee.

If we fail to comply with environmental regulatory requirements, our operating results could be adversely affected.

We face increasing complexity in our product design and procurement operations as we adjust to requirements relating to the materials composition of
many of our products. The European Union has adopted certain directives to facilitate the recycling of electrical and electronic equipment sold in the European Union, including the Restriction on the Use of Certain Hazardous Substances in Electrical
and Electronic Equipment, or RoHS, directive that restricts the use of lead, mercury and certain other substances in electrical and electronic products placed on the market in the European Union after July 1, 2006, and many other countries,
including China, Taiwan and Korea, where the majority of our products are manufactured and packaged and sold, have also adopted similar directives banning or limiting the use of specified substances in products introduced into their domestic
markets. We have incurred costs in connection with our compliance with these environmental laws and regulations, such as costs related to eliminating lead from our semiconductor product packaging. Other environmental regulations may be enacted in
the future, including in the United States, that require us to reengineer our products to utilize components that are compatible with these regulations. and this reengineering and component substitution may result in additional costs to us or
disrupt our operations or logistics. If we or the third-party manufacturers of our products are unable to meet future environmental regulations in a timely manner, it could have a material adverse effect on our business, results of operations and
financial condition.

Certain of our customers products and service providers services are subject to governmental regulation.

Governmental regulation could place constraints on our customers and service providers services and, consequently, reduce
our customers demand for our products. For example, the Federal Communications Commission has broad jurisdiction over products that emit radio frequency signals in the United States. Similar governmental agencies regulate these products in
other countries. Moreover, laws and regulations regarding local cable franchising or satellite broadcasting rights could have an adverse effect on service providers ability to compete in the HD video and multimedia content delivery market.
Although most of our products are not directly subject to current regulations of the Federal Communications Commission or any other federal or state communications regulatory agency, much of the equipment into which these products are incorporated
is subject to



42



---

##### Table of Contents

direct governmental regulation. Accordingly, the effects of regulation on our customers or the industries in which they operate may, in turn, impede sales of our products. For example, demand for
these products will decrease if equipment into which they are incorporated fails to comply with the specifications of the Federal Communications Commission.

Our failure to raise additional capital or generate the significant capital necessary to expand our operations and invest in new products could reduce our ability to compete and could harm our business.

We intend to continue spending substantial amounts to grow our business. We may need to obtain additional financing to pursue
our business strategy, develop new products, respond to competition and market opportunities and acquire complementary businesses or technologies. We may not be able to obtain such financing on favorable terms or at all. The maximum credit available
to us under the terms of our existing Loan and Security Agreement, as amended, with Silicon Valley Bank, or SVB, was reduced in April 2010 from $10.0 million to $5.0 million at our request, but we have no assurance that we will be able to increase
our line of credit or obtain additional credit from other lenders when and if a need arises.

If we were to raise additional capital
through further sales of our equity securities, our stockholders would suffer dilution of their equity ownership. If we engage in debt financing, we may be required to accept terms that restrict our ability to incur additional indebtedness, prohibit
us from paying dividends, repurchasing our stock or making investments, and force us to maintain specified liquidity or other ratios, any of which could harm our business, operating results and financial condition. If we need additional capital and
cannot raise it on acceptable terms, we may not be able to, among other things:



| |  |  | develop or enhance our products;
| | - |  | --------------------------------



| |  |  | continue to expand our product development and sales and marketing organizations;
| | - |  | ---------------------------------------------------------------------------------



| |  |  | acquire complementary technologies, products or businesses;
| | - |  | -----------------------------------------------------------



| |  |  | expand operations, in the United States or internationally;
| | - |  | -----------------------------------------------------------



| |  |  | hire, train and retain employees; or
| | - |  | ------------------------------------



| |  |  | respond to competitive pressures or unanticipated working capital requirements.
| | - |  | -------------------------------------------------------------------------------

Our failure to do any of these things could seriously harm our ability to execute our business strategy and may force us to curtail our research
and development plans or existing operations.

Our effective tax rate may increase or fluctuate, and we may not derive the anticipated tax
benefits from any expansion of our international operations.

Our effective tax rate could be adversely affected by various
factors, many of which are outside of our control. Our effective tax rate is directly affected by the relative proportions of revenue and income before taxes in the various domestic and international jurisdictions in which we operate. We are also
subject to changing tax laws, regulations and interpretations in multiple jurisdictions in which we operate as well as the requirements of certain tax rulings. Changes in applicable tax laws may cause fluctuations between reporting periods in which
the changes take place. If our business opportunities outside the United States continue to grow, we may expand our international operations and staff to better support our expansion into international markets. We anticipate that this expansion will
include the implementation of an international organizational structure that could result in an increasing percentage of our consolidated pre-tax income being derived from, and reinvested in, our international operations. Moreover, we anticipate
that this pre-tax income would be subject to foreign tax at relatively lower tax rates when compared to the U.S. federal statutory tax rate and as a



43



---

##### Table of Contents

consequence, our future effective income tax rate may be lower than the U.S. federal statutory rate. There can be no assurance that significant pre-tax income will be derived from or
reinvested in our international operations, that our international operations and sales will result in a lower effective income tax rate, or that we will implement an international organizational structure. In addition, our future effective income
tax rate could be adversely affected if tax authorities challenge any international tax structure that we implement or if the relative mix of U.S. and international income changes for any reason. Accordingly, there can be no assurance that our
effective income tax rate will be less than the U.S. federal statutory rate.

Our ability to utilize our net operating loss and tax credit
carryforwards may be limited, which could result in our payment of income taxes earlier than if we were able to fully utilize our net operating loss and tax credit carryforwards.

As of December 31, 2010, we had federal and state net operating loss carryforwards of approximately $41.1 million and $32.7 million,
respectively, and federal and state research and development tax credit carryforwards of $12.5 million and $11.4 million, respectively. The tax benefits related to utilization of net operating loss and tax credit carryforwards may be limited
due to ownership changes or as a result of other events. For example, Section 382 of the Internal Revenue Code of 1986, as amended, imposes an annual limitation on the amount of net operating loss carryforwards and tax credit carryforwards
that may be used to offset federal taxable income and federal tax liabilities when a corporation has undergone a significant change in its ownership. While prior changes in our ownership, including as a result of our acquisition of RF Magic, have
resulted in annual limitations on the amount of our net operating loss and tax credit carryforwards that may be utilized in the future, we do not anticipate that such annual limitations will preclude the utilization of substantially all the net
operating loss and tax credit carryforwards described above in the event we remain profitable. However, to the extent our use of net operating loss and tax credit carryforwards is further limited by future offerings or transactions or by our
implementation of an international tax structure or other future events, our income would be subject to cash payments of income tax earlier than it would be if we were able to fully utilize our net operating loss and tax credit carryforwards without
such further limitation.

We devote significant monetary and managerial resources to ensure our compliance with public company regulations.

As a public company, we incur significant legal, accounting and other expenses to ensure our compliance with various public
company regulations, including the Sarbanes-Oxley Act of 2002, or the Sarbanes-Oxley Act, and various rules and regulations adopted by the SEC and The NASDAQ Stock Market, or NASDAQ. The Sarbanes-Oxley Act requires us to maintain effective
disclosure controls and procedures and internal controls for financial reporting, and our management and other personnel devote a substantial amount of time to ensure our compliance with the Sarbanes-Oxley Acts requirements. Compliance with
the Sarbanes-Oxley Act requires us to adopt processes and procedures that make some activities more time-consuming and costly, thereby adding to our cost of operations. To ensure that we are in compliance with the Sarbanes-Oxley Act, and as required
by the Sarbanes-Oxley Act, we perform system and process evaluation and testing of our internal controls over financial reporting annually to allow management and our independent registered public accounting firm to report on the effectiveness of
our internal controls. If we identify deficiencies in our internal controls over financial reporting that are deemed to be material weaknesses, the market price of our stock could decline and we could be subject to sanctions or investigations by
NASDAQ, the SEC or other regulatory authorities.

The SEC and other regulators have continued to adopt new rules and regulations
and make additional changes to existing regulations that require our compliance. For example, on July 21, 2010, the Dodd-Frank Wall Street Reform and Protection Act, or the Dodd-Frank Act, was enacted. There



44



---

##### Table of Contents

are significant corporate governance and executive compensation-related provisions in the Dodd-Frank Act that require the SEC to adopt additional rules and regulations in areas such as say
on pay and proxy access. Our management and other personnel may be required to devote a substantial amount of time to these compliance programs and as a result of the new corporate governance and executive compensation-related rules,
regulations and guidelines prompted by the Dodd-Frank Act and further regulations and disclosure obligations expected in the future, we will likely need to devote additional time and costs to comply with such compliance programs and rules.

If we fail to manage our exposure to global financial and securities market risks successfully, our operating results could be adversely
impacted.

We are exposed to financial market risks, including changes in interest rates, foreign currency exchange rates, credit
markets and prices of marketable equity and fixed-income securities. The primary objective of most of our investment activities is to preserve principal while at the same time maximizing yields without significantly increasing risk. To achieve this
objective, a majority of our marketable investments are investment grade, liquid, fixed-income securities and money market instruments denominated in U.S. dollars. If the carrying value of our investments exceeds the fair value, and the decline in
fair value is deemed to be other-than-temporary, we will be required to write down the value of our investments, which could materially harm our results of operations and financial condition. Moreover, the performance of certain securities in our
investment portfolio is affected by the credit condition of the U.S. financial sector. Although there have been recent signs of improvement within the U.S. financial sector, the sector remains fragile and conditions may deteriorate rapidly, which
could adversely affect the value, realized or unrealized, of our investments and cause us to record significant impairment losses.

Risks Related to
Our Intellectual Property

Our ability to compete and our business could be jeopardized if we are unable to secure or protect our intellectual
property.

We rely on a combination of patent, copyright, trademark and trade secret laws, confidentiality procedures and
licensing arrangements to establish and protect our proprietary rights. However, these legal means afford only limited protection and may not adequately protect our rights or permit us to gain or keep any competitive advantage. Our patent
applications may not issue as patents at all or they may not issue as patents in a form that will be advantageous to us. Our issued patents and those that may issue in the future may be challenged, invalidated, rendered unenforceable or
circumvented, which could limit our ability to stop competitors from marketing related products. Although we have taken steps to protect our intellectual property and proprietary technology, there is no assurance that third parties will not be able
to invalidate, render unenforceable or design around our patents. Furthermore, although we have entered into confidentiality agreements and intellectual property assignment agreements with our employees, consultants and advisors, such agreements may
not be enforceable or may not provide meaningful protection for our trade secrets or other proprietary information in the event of unauthorized use or disclosure or other breaches of the agreements. Moreover, we are required to license any of our
patent claims that are essential to implement MoCA specifications to other MoCA members, who could potentially include our competitors, on reasonable and non-discriminatory licensing terms. In addition, in connection with commercial arrangements
with our customers and the service providers who deploy equipment containing our products, we may be required to license our intellectual property to third parties, including competitors or potential competitors.

Despite our efforts to protect our proprietary rights, unauthorized parties may attempt to copy or otherwise obtain and use our trademarks,
products or technology. Monitoring unauthorized use of our trademarks and technology is difficult and we cannot be certain that the steps we have taken to



45



---

##### Table of Contents

prevent such unauthorized use will be successful, particularly in foreign countries where the laws may not protect our proprietary rights as comprehensively as in the United States. In addition,
if we become aware of a third partys unauthorized use or misappropriation of our trademarks or technology, it may not be practicable, effective or cost-efficient for us to enforce our intellectual property and contractual rights, particularly
where the initiation of a claim might harm our business relationships or risk a costly and protracted lawsuit, including a potential countersuit by a competitor with patents that may implicate our products. If competitors engage in unauthorized use
or misappropriation of our trademarks or technology, our ability to compete effectively could be harmed.

Our participation in patent
pools and standards setting organizations, or other business arrangements, may require us to license our patents to competitors and other third parties and limit our ability to enforce or collect royalties for our patents.

In addition to our existing obligations to license our patent claims that are essential to implement the MoCA specifications to other MoCA members,
in the course of participating in patent pools and other standards setting organizations or pursuant to other business arrangements, we may agree to license certain of our technologies on a reasonable and non-discriminatory basis and, as a result,
our control over the license of such technologies may be limited. We may also be unable to limit to whom we license some of our technologies and may be unable to restrict many terms of the license. Consequently, our competitors may obtain the right
to use our technology. In addition, our control over the application and quality control of our technologies that are included in patent pools or otherwise necessary for implementing industry standards may be limited.

Any dispute with a MoCA member regarding what patent claims are necessary to implement MoCA specifications could result in litigation which could have an
adverse effect on our business.

We are required to grant to other MoCA members a non-exclusive and world-wide license on
reasonable and non-discriminatory terms to any of our patent claims that are essential to implement MoCA specifications. The meaning of reasonable and non-discriminatory has not been settled by the courts, and accordingly, it is not a well-defined
concept. If we had a disagreement with a MoCA member regarding which of our patent claims are necessary to implement MoCA specifications or regarding whether the terms of any license by us under reasonable and non-discriminatory terms fall within
the scope and meaning of reasonable and non-discriminatory, this could result in litigation. Any such litigation, regardless of its merits, could be time-consuming, expensive to resolve, divert our managements time and attention and harm our
reputation. In addition, any such litigation could result in us being required to license on reasonable and non-discriminatory terms certain of our patent claims which we previously believed did not need to be licensed under our MoCA agreement.
Significant disagreements or any litigation between us and any MoCA member regarding patent claims necessary to implement MoCA or the scope and meaning of our reasonable and non-discriminatory terms could have an adverse effect on our business and
harm our competitive position.

Possible third-party claims of infringement of proprietary rights against us, our customers or the service
providers that purchase products from our customers, or other intellectual property claims or disputes, could have a material adverse effect on our business, results of operation or financial condition.

The semiconductor industry is characterized by a high level of litigation based on allegations of infringement of proprietary rights. Numerous U.S.
and foreign issued patents and pending patent applications owned by third parties exist in the fields in which we are selling and developing products. Because patent applications take many years to issue, currently pending applications, known or
unknown to us, may later result in issued patents that we infringe. In addition, third parties continue to

##### Table of Contents

actively seek new patents in our field. It is difficult or impossible to keep fully abreast of these developments and therefore, as we develop new and enhanced products, we may sell or distribute
products that inadvertently infringe patents held by third parties.

We have in the past received, and in the future we, our customers
or the service providers that purchase products from our customers may receive, inquiries from other patent holders and may become subject to claims that we infringe their intellectual property rights. Any intellectual property claim or dispute,
regardless of its merits, could force us, our customers or the service providers that purchase our products from our customers to license the third-partys patents for substantial royalty payments or cease the sale of the alleged infringing
products or use of the alleged infringing technologies, or force us to defend ourselves and possibly our customers or contract manufacturers in litigation. Any cessation of product sales by us, our customers or the service providers that purchase
products from our customers could have a substantial negative impact on our revenues. Any litigation, regardless of its outcome, could result in substantial expense and significant diversion of our managements time and other resources.
Moreover, any such litigation could subject us, our customers or the service providers that purchase our products from our customers to significant liability for damages (including treble damages), temporary or permanent injunctions, or the
invalidation of proprietary rights or require us, our customers or the service providers that purchase products from our customers to license the third-party patents for substantial royalty or other payments.

In addition, we may also be required to indemnify our customers and contract manufacturers for damages they suffer as a result of such infringement
or litigation.

Our use of open source and third-party software could impose limitations on our ability to commercialize our products.

We incorporate open source software into our products, including certain open source code which is governed by the GNU General
Public License, Lesser GNU General Public License and Common Development and Distribution License. The terms of many open source licenses have not been interpreted by U.S. courts, and there is a risk that these licenses could be construed in a
manner that could impose unanticipated conditions or restrictions on our ability to commercialize our products. In such event, we could be required to seek licenses from third parties in order to continue offering our products, make our proprietary
code generally available in source code form (for example, proprietary code that links in particular ways to certain open source modules), which could result in our trade secrets being disclosed to the public and the potential loss of intellectual
property rights in our software, require us to re-engineer our products, discontinue the sale of our products if re-engineering cannot be accomplished on a cost-effective and timely basis, or become subject to other consequences, any of which could
adversely affect our business, operating results and financial condition.

In addition to technologies we have already licensed, we may
find that we need to incorporate certain proprietary third-party technologies, including software programs, into our products in the future. However, licenses to relevant third-party technologies may not be available to us on commercially reasonable
terms, if at all. Therefore, we could face delays in product releases until alternative technology can be identified, licensed or developed, and integrated into our current products. Such alternative technology may not be available to us on
reasonable terms, if at all, and may ultimately not be as effective as the preferred technology. Any such delays or failures to obtain licenses, if they occur, could materially adversely affect our business, operating results and financial
condition.

##### Table of Contents

Because we license some of our software source code directly to customers, we face increased risks that our
trade secrets will be exposed through inadvertent or intentional disclosure, which could harm our competitive position or increase our costs.

We license some of our software source code to our customers, which increases the number of people who have access to some of our trade secrets and other proprietary rights. Contractual obligations of our licensees
not to disclose or misuse our source code may not be sufficient to prevent such disclosure or misuse. The costs of enforcing contractual rights could substantially increase our operating costs and may not be cost-effective, reasonable under the
circumstances or ultimately succeed in protecting our proprietary rights. If our competitors access our source code, they may gain further insight into the technology and design of our products, which would harm our competitive position.

Risks Related to International Operations

We expect a
significant portion of our future revenues to come from our international customers and, as a result, our business may be harmed by political and economic conditions in foreign markets and the challenges associated with operating internationally.

We have derived, and expect to continue to derive, a significant portion of our revenues from international markets. Many of our
customers in Asia incorporate our chipsets into their products that are then sold to U.S.-based service providers. Net revenues outside of the United States comprised 99% and 97% of our total revenues for the year ended December 31, 2010
and 2009, respectively. International business activities involve certain risks, including:



| |  |  | difficulties involved in the staffing and management of geographically dispersed operations;
| | - |  | --------------------------------------------------------------------------------------------



| |  |  | longer sales cycles in certain countries, especially on initial entry into a new geographical market;
| | - |  | -----------------------------------------------------------------------------------------------------



| |  |  | greater difficulty evaluating a customers ability to pay, longer accounts receivable payment cycles and greater difficulty in the collection of past-due
accounts;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | general economic conditions in each country;
| | - |  | --------------------------------------------



| |  |  | challenges associated with operating in diverse cultural and legal environments;
| | - |  | --------------------------------------------------------------------------------



| |  |  | seasonal reductions in business activity specific to certain markets;
| | - |  | ---------------------------------------------------------------------



| |  |  | loss of revenue, property and equipment from expropriation, nationalization, war, insurrection, terrorism and other political risks;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------



| |  |  | foreign taxes and the overlap of different tax structures, including modifications to the U.S. tax code as a result of international trade regulations;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | foreign technical standards;
| | - |  | ----------------------------



| |  |  | changes in currency exchange rates; and
| | - |  | ---------------------------------------



| |  |  | import and export licensing requirements, tariffs, and other trade and travel restrictions.
| | - |  | -------------------------------------------------------------------------------------------

To the extent our international sales are adversely affected by any of these risks or are otherwise unsuccessful, we could experience a reduction
in revenue and our operating results could suffer.

In addition, certain foreign countries where we sell our products, such as China and
Korea, have historically limited recognition and enforcement of contractual and intellectual property rights. In particular, we may have difficulty preventing ODMs and OEMs in these countries from incorporating our inventions, technologies,
copyrights or trademarks into their products without our authorization or without paying us licensing fees. We may also experience difficulty enforcing our intellectual property



48



---

##### Table of Contents

rights in these countries, where intellectual property rights are not as respected as they are in the United States, Japan and Europe. Unauthorized use of our technologies and intellectual
property rights may dilute or undermine the strength of our brand. Further, if we are not able to adequately monitor the use of our technologies by foreign-based ODMs and OEMs, or enforce our intellectual property rights in foreign countries, our
revenue potential could be adversely affected.

Our products are subject to export and import controls that could subject us to liability or
impair our ability to compete in international markets.

Our products are subject to U.S. export controls and may be exported
outside the United States only with the required level of export license or through an export license exception, in most cases because we incorporate encryption technology into our products. In addition, various countries regulate the import of
certain encryption technology and have enacted laws that could limit our ability to distribute our products or could limit our customers ability to implement our products in those countries. Changes in our products or changes in export and
import regulations may create delays in the introduction of our products in international markets, prevent our customers with international operations from deploying our products throughout their global systems or, in some cases, prevent the export
or import of our products to certain countries altogether. Any change in export or import regulations or related legislation, or change in the countries, persons or technologies targeted by such regulations or legislation, could result in decreased
use of our products by, or in our decreased ability to export or sell our products to, existing or potential customers internationally.

In addition, we may be subject to customs duties and export quotas, which could have a significant impact on our revenue and profitability. The
future imposition of significant increases in the level of customs duties or export quotas could have a material adverse effect on our business.

Substantially all of our products are manufactured by third-party contractors located in the Pacific Rim, a region subject to earthquakes and other natural
disasters, as well as economic and political instability. Any disruption to the operations of these contractors could cause significant delays in the production or shipment of our products.

Substantially all of our products are manufactured by third-party contractors located in the Pacific Rim. The risk of an earthquake in this area is
significant due to the proximity of major earthquake fault lines to the facilities of our foundry, assembly and test subcontractors. The occurrence of earthquakes or other natural disasters, or the occurrence of other catastrophic events such as a
pandemic in the region, could result in the disruption of our foundry or assembly and test capacity. In addition, many countries within the Pacific Rim have experienced, and continue to experience, periods of economic and political instability. Any
deterioration in the economic and political conditions in the Pacific Rim that disrupts the operations of our third-party contractors could also result in the disruption of our foundry or assembly and test capacity. Any disruption caused by an
earthquake or other catastrophic event or from the deterioration of economic and political conditions could cause significant delays in the production or shipment of our products until we are able to shift our manufacturing, assembling or testing
from the affected contractor to another third-party vendor. We may not be able to obtain alternate capacity on favorable terms, if at all.

Risks
Related to Ownership of Our Common Stock

Our stock price is volatile and may decline regardless of our operating performance, and you may not
be able to resell your shares at or above the price at which you purchased such shares.

The market price for our common stock is
volatile and may fluctuate significantly in response to a number of factors, most of which we cannot control, including:



| |  |  | price and volume fluctuations in the overall stock market;
| | - |  | ----------------------------------------------------------



49



---

##### Table of Contents

| |  |  | market conditions or trends in our industry or the economy as a whole;
| | - |  | ----------------------------------------------------------------------



| |  |  | changes in operating performance and stock market valuations of other technology companies generally, or those that sell semiconductor products in particular;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the timing of customer or service provider orders that may cause quarterly or other periodic fluctuations in our results that may, in turn, affect the market
price of our common stock;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the seasonal nature of the deployment of products that incorporate our products by certain service providers which may affect the timing of orders for our
products;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the timing of revenue recognition on sales arrangements, which may include multiple deliverables, and the effect of our use of inventory hubbing
arrangements;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the financial projections we may provide to the public, any changes in these projections or our failure to meet these projections;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------



| |  |  | changes in financial estimates or ratings by any securities analysts who follow our common stock, our failure to meet these estimates or failure of those
analysts to initiate or maintain coverage of our common stock;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the publics response to press releases or other public announcements by us or third parties, including our filings with the SEC and announcements relating
to product development, litigation and intellectual property impacting us or our business;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the sustainability of an active trading market for our common stock;
| | - |  | --------------------------------------------------------------------



| |  |  | future sales of our common stock by our executive officers, directors and significant stockholders;
| | - |  | ---------------------------------------------------------------------------------------------------



| |  |  | announcements of mergers or acquisition transactions;
| | - |  | -----------------------------------------------------



| |  |  | announcements of technical innovations, new products or design wins by our competitors or customers;
| | - |  | ----------------------------------------------------------------------------------------------------



| |  |  | other events or factors, including those resulting from war, incidents of terrorism, natural disasters or responses to these events; and
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------



| |  |  | changes in accounting principles.
| | - |  | ---------------------------------

In addition, the stock markets, and in particular The NASDAQ Global Market (the market on which our stock traded in 2010), have experienced extreme price and volume fluctuations that have affected and continue to
affect the market prices of equity securities of many technology companies. Stock prices of many technology companies have fluctuated in a manner unrelated or disproportionate to the operating performance of those companies. In the past,
stockholders have instituted securities class action litigation following periods of market volatility. If we were involved in securities litigation, we could incur substantial costs and our resources and the attention of management could be
diverted from our business.

If securities and/or industry analysts fail to continue publishing research about our business, if they change their
recommendations adversely or if our results of operations do not meet their expectations, our stock price and trading volume could decline.

The trading market for our common stock will be influenced by the research and reports that industry or securities analysts publish about us or our business. If one or more of these analysts cease coverage of our
company or fail to publish reports on us regularly, we could lose visibility in the financial markets, which in turn could cause our stock price or trading volume to decline. In addition, it is likely that in some future period our operating results
will be below the expectations of securities



50

##### Table of Contents

analysts or investors. If one or more of the analysts who cover us downgrade our stock, or if our results of operations do not meet their expectations, our stock price could decline.

Future sales of our common stock or the issuance of securities convertible into or exercisable for shares of our common stock may depress our stock price.

A significant number of shares of our common stock are held by a small number of stockholders. Sales of a substantial number of
shares of our common stock, the issuance of securities convertible into or exercisable for shares of our common stock or the expectation or perception in the market that the holders of a large number of our shares of common stock intend to sell
their shares, could significantly reduce the market price of our common stock. Although the average daily trading volume of our common stock has slowly increased in recent months, our common stock is still less liquid than the stock of companies
with broader public ownership and, as a result, the trading of a relatively small volume of our common stock may have a greater impact on the trading price for our stock and lead to increased volatility in our stock price. In particular, certain
venture capital funds have held shares of our common stock for a substantial period of time and may distribute shares to their limited partners or members at any time and without notice. Any such distribution may result in a substantial number of
our shares being sold, which could have an adverse effect on the trading price of our common stock.

Anti-takeover provisions in our charter
documents and Delaware law might deter acquisition bids for us that you might consider favorable.

Our amended and restated
certificate of incorporation and bylaws contain provisions that may make the acquisition of our company more difficult without the approval of our board of directors. These provisions:



| |  |  | establish a classified board of directors so that not all members of our board are elected at one time;
| | - |  | -------------------------------------------------------------------------------------------------------



| |  |  | authorize the issuance of undesignated preferred stock, the terms of which may be established and shares of which may be issued without stockholder approval, and
which may include rights superior to the rights of the holders of common stock;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | prohibit stockholder action by written consent, which requires all stockholder actions to be taken at a meeting of our stockholders;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------



| |  |  | provide that the board of directors is expressly authorized to make, alter, or repeal our bylaws;
| | - |  | -------------------------------------------------------------------------------------------------



| |  |  | establish advance notice requirements for nominations for elections to our board or for proposing matters that can be acted upon by stockholders at stockholder
meetings; and
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | provide that in addition to any vote required by law or by our amended and restated certificate of incorporation, the approval by holders of at least 66-2/3% of
our then outstanding common stock is required to adopt, amend or repeal any provision of our amended and restated bylaws.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

In addition, because we are incorporated in Delaware, we are governed by the provisions of Section 203 of the Delaware General Corporation Law which, subject to certain exceptions, prohibits stockholders
owning in excess of 15% of our outstanding voting stock from merging or combining with us. These anti-takeover provisions and other provisions under Delaware law could discourage, delay or prevent a transaction involving a change in control of our
company, even if doing so would benefit our stockholders. These provisions could also discourage proxy contests and make it more difficult for you and other stockholders to elect directors of your choosing and cause us to take other corporate
actions you desire.

|(2) | As of December 31, 2009, options to purchase up to 1,072,410 shares of our common stock were outstanding under our RF Magic Plan, Inc. 2000 Incentive Stock Plan, or RF
Magic Plan. During 2010, 14,252 of these options were cancelled without being exercised and options to purchase 708,554 shares of common stock were exercised at a weighted average exercise price of $0.67 per share. As of December 31, 2010,
options to purchase up to 349,604 shares of our common stock remained outstanding under the RF Magic Plan.
|--- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(3) | In connection with our acquisition of RF Magic, we entered into put and call option agreements pursuant to which we are obligated to issue shares of our common stock in exchange
for the shares of RF Magics common stock issuable upon exercise of stock options held by employees of RF Magics French subsidiary. Although we acquired RF Magics French subsidiary in connection with the acquisition, we did not
assume the options held by the employees of the French subsidiary. As of December 31, 2009, there were 34,580 shares of our common stock subject to the put and call option agreements. During 2010, 5,294 of these options were cancelled
without being exercised and options to purchase 18,038 shares of common stock were exercised and exchanged at a weighted average exercise price of $0.43 per share. As of December 31, 2010, we remain obligated to issue up to 11,248 shares
of our common stock in exchange for the shares of RF Magics common stock issuable upon exercise of options held by the employees of our French subsidiary.

All of the offers, sales and issuances of the securities described in paragraphs (1) and (2) were deemed to be exempt from registration under the Securities Act of 1933, as amended, or the Securities Act,
in reliance on Rule 701 in that the transactions were under compensatory benefit plans and contracts relating to compensation as provided under Rule 701. The recipients of such securities were our employees, directors or bona fide consultants and
received the securities under the 2001 Plan or RF Magic Plan, as the case may be. Appropriate legends were affixed to the securities issued in these transactions to the extent required. Each of the recipients of securities in these transactions had
adequate access, through employment, business or other relationships, to information about us.

The issuance of the shares of our common
stock described in paragraph (3) was deemed to be exempt from registration under the Securities Act in reliance on Section 3(A)(10) of the Securities Act after a fairness hearing before the California Department of Corporations.

Issuer Purchases of Equity Securities

Pursuant to the terms of the 2001 Plan, options may be exercised prior to vesting. Shares of common stock issued prior to vesting that remain unvested are subject to a repurchase option in our favor that lapses in
accordance with the original vesting schedule for the option. During the three months ended December 31, 2010, we did not repurchase any shares of our common stock.

|Item 7. | Managements Discussion and Analysis of Financial Condition and Results of Operations
|------- | -------------------------------------------------------------------------------------

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with the information
under Part II, Item 6, Selected Financial Data and our consolidated financial statements and related notes appearing elsewhere in this Annual Report. In addition to historical information, this discussion and analysis contains forward-looking
statements that involve risks, uncertainties and assumptions. Our actual results may differ materially from those anticipated in these forward-looking statements as a result of certain factors, including but not limited to those set forth under Part
I, Item 1A, Risk Factors and elsewhere in this Annual Report.

Overview

Entropic Communications is a leading fabless semiconductor company that designs, develops and markets systems solutions to enable connected home
entertainment. Our technologies significantly change the way high-definition television-quality video, or HD video, standard-definition television-quality video, or SD video, and other multimedia content such as movies, music, games and photos are
brought into and delivered throughout the home.

We are a pioneer of key technologies that enable connected home networking of digital
entertainment over existing coaxial cable. We are a founding member of Multimedia over Coax Alliance, or MoCA, a global home networking consortium that sets standards for the distribution of video and other multimedia entertainment over coaxial
cable. Our products include integrated circuits and related software associated with:



| |  |  | home networking solutions based on the MoCA standard;
| | - |  | -----------------------------------------------------



| |  |  | direct broadcast satellite, or DBS, services;
| | - |  | ---------------------------------------------



| |  |  | high-speed broadband access; and
| | - |  | --------------------------------



| |  |  | silicon tuners.
| | - |  | ---------------

Our products
allow telecommunications carriers, cable operators and DBS service providers, which we collectively refer to as service providers, as well as providers of over-the-top, or OTT, services, to enhance and expand their service offerings and reduce
deployment costs in an increasingly competitive environment. Our MoCA home networking solutions are now being deployed into consumer homes to support multi-room digital video recorder, or DVR, service by Comcast, Cox, DIRECTV, Time Warner Cable and
Verizon, as well as by a number of smaller service providers.

In December 2004, we introduced and commenced commercial shipments of our
home networking products. In the first quarter of 2006, we began commercially shipping our broadband access solutions. In May 2007, we acquired Arabella Software Ltd., or Arabella, a developer of embedded software. In June 2007, we acquired RF
Magic, a provider of digital broadcast satellite outdoor unit and silicon tuner solutions. In 2008, we acquired certain specified assets of Vativ Technologies, Inc., or Vativ, a provider of high-bandwidth, advanced digital processing solutions for
digital television and 10 gigabit Ethernet markets. Since inception, we have invested heavily in product development and have only recently achieved profitability on an annual basis, with a net income of $64.7 million for the year ended
December 31, 2010. In 2010, our net revenues increased to $210.2 million from $116.3 million in 2009 which was primarily due to the increased demand for our home networking products and our DBS products, which is directly related to the
increased deployment of our products into consumer homes by satellite and cable operators. Our net revenues decreased from $146.0 million in 2008 to $116.3 million in 2009, driven primarily by softness in demand for our home networking products and,
to a lesser extent, by lower demand for our DBS products. As of December 31, 2010, we had an accumulated deficit of $177.2 million.

##### Table of Contents

We generate the majority of our revenues from sales of our products to original design manufacturers,
or ODMs, and original equipment manufacturers, or OEMs, that provide customer premises equipment to service providers. We price our products based on market and competitive conditions and reduce the price of our products over time, as market and
competitive conditions change, and as manufacturing costs are reduced. Our markets are generally characterized by declining average selling prices over the life of a product and, accordingly, we must reduce costs and successfully introduce new
products and enhancements to maintain our gross margins.

We rely on a limited number of customers for a significant portion of our net
revenues. Sales to these customers are in turn driven by service providers that purchase our customers products which incorporate our products. A substantial percentage of our net revenues are dependent upon five major service providers:
Comcast, DIRECTV, DISH Network, Time Warner Cable and Verizon. In addition, we are dependent on sales outside of the United States for almost all of our net revenues and expect that to continue in the future.

We use third-party foundries and assembly and test contractors to manufacture, assemble and test our products. This outsourced manufacturing
approach allows us to focus our resources on the design, sales and marketing of our products and avoid the cost associated with owning and operating our own manufacturing facility. A significant portion of our cost of net revenues consists of
payments for the purchase of wafers and for manufacturing, assembly and test services.

We expect research and development expenses in
future years to continue to increase in total dollars as we develop additional products and expand our business, and to fluctuate over the course of the year based on the timing of our development tools and supply costs, which include outside
services, masks costs and software licenses. We also anticipate that our sales and marketing expenses will increase as we expand our domestic and international sales and marketing organization and activities and build brand awareness. Due to the
lengthy sales cycles that we face, we may experience significant delays from the time we incur research and development and sales and marketing expenses until the time, if ever, that we generate sales from the related products.

Since our inception, we have funded our operations using a combination of preferred stock issuances, cash collections from customers, bank credit
facilities, cash received from the exercise of stock options and proceeds from public offerings of our common stock. For example, on October 5, 2010, we completed a public offering of 10,750,000 shares of our common stock, which resulted in net
proceeds of approximately $99.3 million. We intend to continue spending substantial amounts in connection with the growth of our business to pursue our business strategy, develop new products, respond to competition and market opportunities, and
possibly acquire complementary businesses or technologies.

Critical Accounting Policies and Estimates

Our consolidated financial statements are prepared in accordance with United States generally accepted accounting principles, or GAAP. These
accounting principles require us to make certain estimates and judgments that affect the reported amounts of assets and liabilities as of the dates of the consolidated financial statements, the disclosure of contingencies as of the dates of the
consolidated financial statements, and the reported amounts of net revenues and expenses during the periods presented. Although we believe that our judgments and estimates are reasonable under the circumstances, actual results may differ from those
estimates. If actual results or events differ materially from those contemplated by us in making these estimates, our reported financial condition and results of operations for future periods could be materially affected.

Revenue
Recognition

Our net revenues are generated principally by sales of our semiconductor products. During the years ended
December 31, 2010, 2009 and 2008, product net revenues represented more than 99% of our total net revenues.

Our sales
primarily occur through the efforts of our direct sales force. The remainder of our sales occurs through third-party sales representatives and distributors. During the years ended December 31, 2010, 2009 and 2008, more than 99% of our
sales occurred through the efforts of our direct sales force.

We recognize product revenues when the following fundamental criteria are
met: (i) persuasive evidence of an arrangement exists, (ii) delivery has occurred or services have been rendered, (iii) the price to the customer is fixed or determinable, and (iv) collection of the resulting receivable is
reasonably assured. These criteria are usually met at the time of product shipment; however, we do not recognize revenue until all substantive customer acceptance requirements have been met, when applicable.

A portion of our sales is made through distributors, agents or customers acting as agents under agreements allowing for pricing credits and/or
rights of return. Product net revenues on sales made through these distributors are not recognized until the distributors ship the product to their customers.

Revenues derived from billing customers for shipping and handling costs are classified as a component of net revenues. Costs of shipping and handling charged by suppliers are classified as a component of cost of
net revenues.

We record reductions to net revenues for estimated product returns and pricing adjustments, such as competitive pricing
programs, in the same period that the related revenue is recorded. The amount of these reductions is based on historical sales returns and other factors known at the time. If actual returns differ significantly from our estimates, such differences
would be recorded in our results of operations for the period in which the actual returns become known. To date, changes in estimated returns have not been material to net revenues in any related period.

We are party to an inventory hubbing agreement with Motorola. Pursuant to this agreement, we deliver products to the designated
third-party warehouse based upon Motorolas projected needs, but do not recognize product revenue unless and until Motorola removes our products from the third-party warehouse to incorporate into its own products.

We receive royalties in exchange for an exclusive right to manufacture and sell certain products. We
have determined that we are not able to reliably estimate the royalties earned in the period the sales occur and, as a result, we record net revenues based on cash receipts. The royalty revenues recorded during the years ended
December 31, 2010, 2009 and 2008 were $1.2 million, $1.9 million and $2.9 million, respectively, and are included in net revenues in the accompanying consolidated statements of operations.

We have entered into agreements to license certain hardware and software, also referred to as the nodes, to certain members of MoCA for
a period of three years and to provide upgrades when and if they become available. The agreements limit the rights to use the nodes to test compliance of the members own products to the MoCA specification. For these arrangements, we defer all
of the license revenues when the nodes are delivered and recognize the revenues on a straight-line basis over the three-year term of the agreement.

We provide rebates on our products to certain customers. At the time of the sale, we accrue 100% of the potential rebate as a reduction to net revenue and do not apply a breakage factor. The amount of these
reductions is based upon the terms included in various rebate agreements. We reverse the accrual for unclaimed rebate amounts as specific rebate programs contractually end or when we believe unclaimed rebates are no longer subject to payment and
will not be paid. For the years ended December 31, 2010, 2009 and 2008, we reduced net revenue by $0.6 million, $0.7 million and $0.8 million, respectively, in connection with our rebate programs.

We occasionally enter into agreements where revenue is derived from multiple deliverables including any mix of products and/or services. These
products and/or services are generally delivered from approximately three months to two years after the execution date. Revenue recognition for agreements with multiple deliverables is based on the individual units of accounting determined to exist
in the agreement. A delivered item is considered a separate unit of accounting when the delivered item has value to the customer on a stand-alone basis. Items are considered to have stand-alone value when they are sold separately by any vendor or
when the customer could resell the item on a stand-alone basis.

For multiple deliverable agreements entered into after
December 31, 2009, consideration is allocated at the inception of the agreement to all deliverables based on their relative selling price. The relative selling price for each deliverable is determined using vendor specific objective evidence,
or VSOE, of selling price or third-party evidence of selling price if VSOE does not exist. If neither VSOE nor third-party evidence of selling price exists, we use our best estimate of the selling price for the deliverable. To date, multiple
deliverable contracts have not been material to net revenues in any related period and our adoption of the new accounting guidance for determining multiple element arrangements effective January 1, 2010 did not have an impact on our operating
results.

For multiple deliverable agreements entered into on or prior to December 31, 2009, consideration was generally allocated
to each unit of accounting based upon its relative fair value when objective and reliable evidence of fair value existed for all units of accounting in the agreement. The fair value of an item was generally the price charged for the product, if the
item was regularly sold on a stand-alone basis.

In order to establish VSOE of selling price, we must regularly sell the product and/or
service on a standalone basis with a substantial majority priced within a relatively narrow range. VSOE of selling price is usually the midpoint of that range. If there is not a sufficient number of standalone sales and VSOE of selling price cannot
be determined, then we consider whether third-party evidence can be used to establish the selling price. If neither VSOE nor third-party evidence of selling price exists, effective January 1, 2010 we determine our best estimate of selling price
using average selling prices

##### Table of Contents

over a rolling 12-month period as well as market conditions. If the product or service has no history of sales, we rely upon sales prices set by our pricing committee, adjusted for applicable
discounts.

We recognize revenue for delivered elements only when we determine there are no uncertainties regarding customer acceptance.
Changes in the allocation of the sales price between delivered and undelivered elements can impact the revenue recognition but do not change the total revenue recognized on any agreement.

Warranty Accrual

We generally provide a warranty on our products for a period of one
year; however, it may be longer for certain customers. Accordingly, we establish provisions for estimated product warranty costs at the time revenue is recognized based upon our historical activity and, additionally, for any known product warranty
issues. Warranty provisions are recorded as a cost of net revenues. The determination of such provisions requires us to make estimates of product return rates and expected costs to replace or rework the products under warranty. When the actual
product failure rates, cost of replacements and rework costs differ from our estimates, revisions to the estimated warranty accrual are made. Actual claims are charged against the warranty reserve.

Inventories

Inventories are stated
at the lower of cost (first-in, first-out) or market. Lower of cost or market adjustments reduce the carrying value of the related inventory and take into consideration reductions in sales prices, excess inventory levels and obsolete inventory.
These adjustments are calculated on a part-by-part basis and, in general, represent excess inventory value on hand compared to 12-month demand projections. Once established, these adjustments are considered permanent and are not reversed until the
related inventory is sold or disposed.

We have entered into a capacity agreement with one of our third-party foundry contractors in
order to guarantee minimum capacity volumes on our digital outdoor unit and silicon tuner products. Pursuant to the capacity agreement, we have made prepayments which will result in reduced prices paid on future inventory purchases up to a specified
volume. The prepayments are being amortized into the cost of our inventory purchases based on the specified volume commitments under the terms of the capacity agreement. The prepaid inventory volume commitments are assessed for impairment on a
periodic basis by comparing the remaining prepaid balance to our estimate of remaining purchases. There have been no impairments to date.

Stock-Based Compensation

We have
equity incentive plans under which incentive stock options have been granted to employees and restricted stock units and non-qualified stock options have been granted to employees and non-employees. We also have an employee stock purchase plan for
all eligible employees.

Our stock-based compensation cost is measured at the grant date, based on the estimated fair value of the
award, and is recognized as an expense over the employees requisite service period. We have no stock-based compensation awards with market or performance conditions. The stock-based compensation expense attributable to awards under our 2007
Employee Stock Purchase Plan, or ESPP, was determined using the Black-Scholes option pricing model.

We also grant awards to
non-employees and determine the fair value of such stock-based compensation awards granted as either the fair value of the consideration received or the fair value of



62

##### Table of Contents

the equity instruments issued, whichever is more reliably measurable. If the fair value of the equity instruments issued is used, it is measured using the stock price and other measurement
assumptions as of the earlier of (i) the date at which a commitment for performance by the counterparty to earn the equity instruments is reached, or (ii) the date at which the counterpartys performance is completed.

We recognize excess tax benefits associated with stock-based compensation to stockholders equity only when realized. When assessing whether
excess tax benefits relating to stock-based compensation have been realized, we follow the with and without approach excluding any indirect effects to be realized until after the utilization of all other tax benefits available to us.

Goodwill and Intangible Assets

We record goodwill and other intangible assets based on the fair value of the assets acquired. In determining the fair value of the assets acquired, we utilize extensive accounting estimates and judgments to
allocate the purchase price to the fair value of the net tangible and intangible assets acquired. We use the discounted cash flow method to estimate the value of intangible assets acquired. The estimates used to value and amortize intangible assets
are consistent with the plans and estimates that we use to manage our business and are based on available historical information and industry estimates and averages.

We assess goodwill and certain intangible assets for impairment using fair value measurement techniques on an annual basis, during the fourth quarter of the year or more frequently if indicators of impairment
exist. We perform an interim goodwill impairment test when it is more likely than not that the fair value of a reporting unit is less than the carrying amount. We operate as one reporting unit. The goodwill impairment test compares the implied fair
value of the reporting units goodwill with the carrying amount of that goodwill to measure the amount of the impairment loss, if any. The implied fair value of goodwill is determined in the same manner as in a business combination. Determining
the fair value of the implied goodwill is judgmental in nature and often involves the use of significant estimates and assumptions. These estimates and assumptions could have a significant impact on whether or not an impairment charge is recognized
and also the magnitude of any such charge. Estimates of fair value are primarily determined using discounted cash flows and market comparisons. These approaches use significant estimates and assumptions, including the size and timing of deployments
by our customers and related projections and timing of future cash flows, discount rates reflecting the risk inherent in future cash flows, perpetual growth rates, stage of products in development, determination of appropriate market comparables,
and determination of whether a premium or discount should be applied to comparables.

Accounting for Income Taxes

We estimate income taxes based on the various jurisdictions where we conduct business. Significant judgment is required in determining our worldwide
income tax provision. We estimate the current tax liability and assess temporary differences that result from differing treatments of certain items for tax and accounting purposes. These differences result in deferred tax assets and liabilities,
which are reflected in our balance sheets. We then assess the likelihood that deferred tax assets will be realized. A valuation allowance is recorded when it is more likely than not that some of the deferred tax assets will not be realized. When a
valuation allowance is established or increased, we record a corresponding tax expense in our statements of operations. We review the need for a valuation allowance each interim period to reflect uncertainties about whether we will be able to
utilize deferred tax assets before they expire. The valuation allowance analysis is based on estimates of taxable income for the jurisdictions in which we operate and the periods over which our deferred tax assets will be realizable.

##### Table of Contents

We recognize and measure benefits for uncertain tax positions using a two-step approach. 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 the tax position will be sustained upon audit, including resolution
of any related appeals or litigation processes. For tax positions that are more likely than not of being sustained upon audit, the second step is to measure the tax benefit as the largest amount that has more than a 50% chance of being realized upon
settlement. Significant judgment is required to evaluate uncertain tax positions. We evaluate uncertain tax positions on a quarterly basis. The evaluations are based upon a number of factors, including changes in facts or circumstances, changes in
tax law, correspondence with tax authorities during the course of audits and effective settlement of audit issues.

In assessing the
realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will be realized. The ultimate realization of deferred tax assets is dependent upon the generation of
future taxable income during the periods in which those temporary differences become deductible. During the fourth quarter of 2010, we concluded that it was more likely than not that we would be able to realize the benefit of our federal deferred
tax assets in the future. We based this conclusion on historical and projected operating performance, as well as our expectation that our operations will generate sufficient taxable income in future periods to realize the tax benefits associated
with the deferred tax assets. As a result, we reduced the valuation allowance on a portion of our net deferred tax assets by $31.6 million at December 31, 2010. We will continue to assess the need for a valuation allowance on the deferred
tax asset by evaluating both positive and negative evidence that may exist. Any adjustment to the net deferred tax asset valuation allowance would be recorded in the income statement for the period that the adjustment is determined to be required.

Segment Reporting

We are
organized as, and operate in, one reportable segment: the design, development and sale of silicon integrated circuits. Products within this segment are embedded in electronic devices used to enable the delivery of multiple streams of HD video and
other multimedia content for entertainment purposes into and throughout the home. Our chief operating decision maker is our chief executive officer, or CEO. Our CEO reviews financial information presented on a consolidated basis for the purpose of
evaluating financial performance and allocating resources. There are no segment managers who are held accountable for operations below the consolidated financial statement level. Our assets are primarily located in the United States and not
allocated to any specific region. Therefore, geographic information is presented only for total revenue.

Recently Issued Accounting Standards

In October 2009, the Financial Accounting Standards Board, or FASB, issued authoritative guidance for arrangements with multiple
deliverables. The guidance will allow companies to allocate arrangement consideration in multiple deliverable arrangements in a manner that is intended to better reflect the transactions economics. The guidance also removes non-software
components of tangible products and certain software components of tangible products from the scope of existing software revenue guidance. The new guidance requires expanded qualitative and quantitative disclosures and is effective for fiscal years
beginning on or after June 15, 2010. Early adoption of the guidance is permitted. We have adopted this guidance effective January 1, 2010 and the application of this guidance did not have a material impact on our consolidated financial
statements.

In March 2010, the FASB ratified the milestone method of revenue recognition. Under this new standard, an entity can
recognize contingent consideration earned from the achievement of a substantive milestone in its entirety in the period in which the milestone is achieved. A milestone is



64

##### Table of Contents

defined as an event (i) that can only be achieved based in whole or in part on either the entitys performance or on the occurrence of a specific outcome resulting from the
entitys performance, (ii) for which there is substantive uncertainty at the date the arrangement is entered into that the event will be achieved, and (iii) that would result in additional payments being due to the entity. The
milestone method of revenue recognition is effective for fiscal years beginning on or after June 15, 2010 and may be applied prospectively after the adoption date or retrospectively for all periods presented. The impact of adoption on our
consolidated financial statements will ultimately depend on the terms of any future business transactions.

Net Revenues.We generate net revenues principally by sales of our semiconductor
products. We also generate service revenues from development contracts. We principally sell our products directly to either ODMs or OEMs. We price our products based on market and competitive conditions, and periodically reduce the price of our
products as market and competitive conditions change and as manufacturing costs are reduced. Our markets are generally characterized by declining average selling prices over the life of a product and, accordingly, we must reduce costs and
successfully introduce new products and enhancements to maintain our gross margins.

We currently rely, and expect to continue to rely,
on a limited number of customers for a significant portion of our net revenues. For the years ended December 31, 2010, 2009 and 2008, four customers accounted for 56%, 58% and 74% of our net revenues, respectively. In addition, we depend
on a limited number of service providers that purchase products from our customers that incorporate our products. To date, only a limited number of major service providers, such as Verizon, DIRECTV, Time Warner Cable, Cox, Comcast and Bright House
Networks LLC have publicly announced their intention to use the MoCA standard for home networking. We also primarily rely on two major service providers, DISH Network and DIRECTV, to deploy products using our DBS outdoor unit solutions. During the
year ended December 31, 2009, products sold to our customers that were incorporated into products purchased by Verizon, DISH Network and DIRECTV accounted for

substantially all of our net revenues. However, during the year ended December 31, 2010, in addition to Verizon, DISH Network and DIRECTV, we also generated meaningful revenues from the sale
of our products to our customers that were incorporated into products purchased by Comcast, Time Warner Cable and Cox. To date, the FiOS deployment by Verizon and the DIRECTV multi-room DVR and SWiM dish deployments have been major drivers of our
net revenues. We expect that we will continue to derive significant revenues from Verizon and DIRECTV, but our reliance on Verizon and DIRECTV as the major driver of our net revenues is decreasing as other service providers, such as Time Warner
Cable, Comcast and Cox deploy our home networking products.

Since inception, we have derived our net revenues primarily from Asia, the
United States and other North American countries. Net revenues are allocated to the geographic region based on the shipping destination of customer orders. For sales to ODMs and OEMs, their geographic locations may differ from those of the ultimate
end customers. Of our $210.2 million in net revenues in 2010, $195.1 million, $12.1 million and $3.1 million were derived from Asia, North America and Europe, respectively. Of our $116.3 million in net revenues in 2009, $107.1 million, $7.0 million
and $2.2 million were derived from Asia, North America and Europe, respectively. Of our $146.0 million in net revenues in 2008, $139.2 million, $3.9 million and $2.9 million were derived from Asia, Europe and North America, respectively.

Accordingly, we are dependent on sales outside of the United States for most of our net revenues and expect that to continue in the future.

Cost of Net Revenues.We use third-party foundries and assembly and test contractors to manufacture,
assemble and test our products. A significant portion of our cost of net revenues consists of payments for the purchase of wafers and for manufacturing, assembly and test services. To a lesser extent, cost of net revenues includes expenses relating
to management of our contractors, the cost of shipping and logistics, royalties, inventory valuation charges taken for excess and obsolete inventory, warranty costs, changes in product cost due to changes in wafer manufacturing, assembly and test
yields, allocated facilities expenses, amortization of inventory step-up and acquired developed technology. We currently outsource the manufacturing of our home networking and broadband access products principally to TSMC, and the manufacturing of
our digital broadcast satellite outdoor unit and silicon tuner products to TowerJazz. Our home networking and broadband access products are primarily assembled and tested by Amkor, while our digital broadcast satellite outdoor unit and silicon tuner
products are primarily assembled by Amkor and tested by Giga Solution. In September 2010, we entered into a Capacity Commitment Agreement with TowerJazz in order to guarantee minimum capacity volumes on our digital broadcast satellite outdoor unit
and silicon tuner products through December 31, 2012.

Gross Margin.    Our gross margins have increased
each year from 2008 to 2010, primarily due to decreased unit costs of our home networking chipsets principally as a result of more favorable manufacturing costs and the increase in the revenues generated from our digital broadcast satellite outdoor
products, which carry a higher gross margin as compared to our home networking products. Included in cost of net revenues for the years ended December 31, 2010, 2009 and 2008 was the amortization of developed technology of $1.6 million,
$1.6 million and $6.0 million, respectively, which resulted from our RF Magic and Vativ acquisitions. Our gross margin has been and will continue to be affected by a variety of factors, including declines in selling prices of our products,
especially as competition increases over time, product mix, the timing of cost reductions for fabricated wafers and assembly and test service costs, inventory valuation charges, purchase accounting-related charges, and changes in wafer
manufacturing, assembly and test yields.

Research and Development Expenses.Research and development
expenses primarily include costs related to personnel, third-party services that consist primarily of contract labor services, fabrication masks, architecture licenses, engineering design development software and hardware

tools, allocated facilities expenses and depreciation of equipment used in research and development. While a substantial portion of our research and development activities are undertaken in
support of our current and anticipated customers, we also invest in research and development to develop our technology. In the future, we expect some of the services currently performed by contractors to be performed internally.

We expect research and development expenses in future years to continue to increase in total dollars. We anticipate that our research and
development expenses may fluctuate over the course of a year based on the timing of our development tools and supply costs, which include third-party services, masks costs and licenses.

Sales and Marketing Expenses.Sales and marketing expenses primarily include costs related to personnel, sales
commissions, trade shows, marketing programs, depreciation and allocated facilities expenses. We plan to continue to increase the size of our sales and marketing organization to enable us to expand into existing and new markets. We also plan to
continue to invest in expanding our domestic and international sales and marketing activities and build brand awareness. Due to the lengthy sales cycles that we face, we may experience significant delays from the time we incur research and
development and sales expenses until the time, if ever, that we generate sales from these products.

General and Administrative
Expenses.General and administrative expenses primarily include costs related to personnel, accounting and tax, legal compliance and allocated support expenses. We expect that in future years our general and administrative
expenses will increase as we incur additional costs associated with supporting our business growth.

Our net revenues for 2010 were $210.2
million, as compared to net revenues of $116.3 million in 2009, an increase of $93.9 million or 81%. The increase in net revenues for 2010 was primarily driven by higher demand for our home networking products, including new deployments by
additional service providers and by higher demand for our DBS outdoor unit products.

Our net revenues for 2009 were $116.3 million, as
compared to net revenues of $146.0 million in 2008, a decrease of $29.7 million or 20%. The decrease in net revenues for 2009 was primarily driven by lower demand for our home networking products and, to a lesser extent, from lower demand of DBS
outdoor unit chips.

Gross profit for 2010 was $112.2 million, an
increase of $53.3 million, or 90%, from gross profit of $58.9 million in 2009. This increase was primarily due to higher net revenues from the sales of our home networking products and our DBS outdoor unit products. Additionally, gross margin
increased due to lower unit costs of both our home networking products and our DBS outdoor unit products, principally as a result of more favorable manufacturing costs, and a higher contribution to gross margin from the sales of our DBS outdoor unit
products.

Gross profit for 2009 was $58.9 million, a decrease of $7.7 million, or 12%, from gross profit of $66.6 million in 2008. This
decrease was primarily due to lower net revenues from the sales of our home networking chipsets and our DBS outdoor unit products, offset by lower amortization in the developed technology and improvement in the gross margin of our home networking
chipsets. Gross margin percentage increased from 46% for 2008 to 51% for 2009 primarily due to a decrease in the amortization of developed technology. Additionally, gross margin percentage increased due to lower unit costs of our home networking
chipsets, principally as a result of more favorable manufacturing costs, and slightly higher contribution to gross margin from the sales of our DBS outdoor unit products.

Our gross profit and gross margin are impacted by the inclusion of amortization of developed technology in cost of net revenues. The amortization results from our acquisitions of RF Magic and Vativ as we used the
purchase method of accounting and, as a result of the application of the purchase method, included in cost of net revenues for 2010, 2009 and 2008 was $1.6 million, $1.6 million and $6.0 million, respectively, of amortization of developed
technology. The decrease in this amortization expense of $4.4 million from 2008 to 2009 had a positive impact on our 2009 gross margins.

Research and development expenses increased by
$3.5 million, or 8%, from $45.2 million in 2009 to $48.7 million in 2010. This $3.5 million increase was primarily due to increased personnel costs of $1.6 million (of which $0.5 million was due to stock-based compensation) which was
primarily attributable to the combination of a 10% increase in the number of employees engaged in research and development activities and the increase in variable compensation due to the achievement of operational, financial and business development
objectives in 2010. Other factors contributing to the increase in research and development expense include a $1.9 million increase in development tools and supply costs, which include third-party services, masks costs and licenses that fluctuate in
timing and amount from period to period, all of which resulted from a general increase in research and development activities due to additional research and development projects that were being worked on in 2010 as compared to 2009.

##### Table of Contents

Research and development expenses decreased by $10.6 million, or 19%, from $55.8 million in 2008 to
$45.2 million in 2009. This $10.6 million decrease was primarily due to decreased personnel costs of $8.9 million (of which $2.5 million was due to stock-based compensation) mainly resulting from a 17% decrease in the number of employees
engaged in research and development activities due to the implementation of our March 2009 restructuring plan. Other factors contributing to the decrease in research and development expense include a $1.7 million reduction in development tools and
supply costs, which include third-party services, masks costs and licenses that fluctuate in timing and amount from period to period, all of which resulted from a general decrease in research and development activities due to our March 2009
restructuring plan, which included the cancellation of the development of our advanced network processor architecture and an associated product that was being staffed primarily out of our Kfar Saba, Israel location.

Sales and marketing expenses increased by $3.2
million, or 23%, from $14.0 million in 2009 to $17.2 million in 2010. This $3.2 million increase included increased personnel costs of $2.7 million (of which $0.2 million was due to stock-based compensation) which was primarily
attributable to the combination of a 15% increase in the number of employees engaged in sales and marketing activities and the increase in variable compensation due to the achievement of operational, financial and business development objectives in
2010. The remainder of the increase in sales and marketing expenses, including increases in marketing and trade show costs of $0.3 million and increases in travel-related costs of $0.3 million and was primarily due to a general increase in business
activities as a result of the increase in the number of employees engaged in sales and marketing activities during 2010.

Sales and
marketing expenses decreased by $2.3 million, or 14%, from $16.3 million in 2008 to $14.0 million in 2009. This $2.3 million decrease included decreased personnel costs of $1.6 million (of which $0.9 million was due to stock-based
compensation) which was primarily attributable to a 4% decrease in the number of employees engaged in sales and marketing activities resulting primarily from our March 2009 restructuring plan. The remainder of the decrease in sales and marketing
expenses, including decreases in travel related costs of $0.3 million and marketing and trade show costs of $0.3 million, was primarily due to a general decrease in business activities as a result of the decrease in the number of employees engaged
in sales and marketing activities during 2009.

General and administrative expenses increased
by $2.3 million, or 21%, from $10.9 million in 2009 to $13.1 million in 2010. This $2.3 million increase was driven by increased personnel costs of $2.0 million (of which $0.2 million was due to stock-based compensation) which was
primarily attributable to the combination of a 10% increase in the number of employees engaged in general and administrative activities and the increase in variable compensation due to the achievement of operational, financial and business
development objectives in 2010.

General and administrative expenses decreased by $1.9 million, or 15%, from $12.8 million in 2008 to
$10.9 million in 2009. This $1.9 million decrease in general and administrative expenses was primarily driven by decreases in non-personnel expenses including third-party services of $1.0 million, legal fees of $0.2 million and recruiting fees of
$0.3 million, primarily due to a general decrease in business activities. Additionally, personnel costs decreased by $0.2 million, primarily attributable to a small decrease in the number of employees engaged in general and administrative activities
during 2009.

Write Off of In-Process Research and Development

We recorded an In-Process Research and Development, or IPR&D, expense of $1.3 million in 2008 which related to the High Definition Multimedia
Interface, or HDMI, switch products that we acquired from Vativ in April 2008 because the acquired technology had not yet reached technological feasibility and had no alternative future uses. A discounted cash flow approach was utilized in valuing
the IPR&D. The value of the technology was the sum of the present value of projected debt-free net income, in excess of returns on requisite assets, over the economic life of the IPR&D. No IPR&D write-offs were recorded in 2009 or 2010.

Amortization of Intangible Assets

Amortization of intangible assets of $16,000 and $2.7 million was incurred during 2009 and 2008, respectively. The amortization of intangible assets in 2009 were from intangible assets acquired through the
acquisition of RF Magic in June 2007. The amortization of intangible assets in 2008 were from intangible assets acquired through the acquisitions of Vativ in April 2008, RF Magic in June 2007 and Arabella in May 2007. No amortization
of intangible assets were recorded during 2010.

Restructuring Charges

We incurred restructuring charges of $2.2 million in 2009 resulting from a restructuring plan we implemented in March 2009 that resulted in a
worldwide reduction-in-force of 55 employees and the closure of our Nice, France and Kfar Saba, Israel offices. All of the terminated employees received severance payments upon their effective termination. In addition, the affected French and
Israeli employees continued to receive salaries until their termination became effective upon the expiration of applicable contractual or statutory notice periods.

The continued payment of salaries to the terminated Nice and Kfar Saba employees during their respective notice periods represented a one-time termination benefit since we were required by contract or law to make
these payments whether or not these employees continued to work for us through their actual termination dates.

In 2008, we incurred
restructuring charges totaling $1.3 million as a result of two restructuring plans in 2008. In February 2008, we implemented a restructuring plan to exit the operating lease of our former corporate headquarters in San Diego, California. The original
lease was effective through May 2010. No employees were terminated in connection with the February 2008 restructuring plan. In May 2008, we entered into an agreement with our landlord to terminate our operating lease, resulting in the completion of
our restructuring plan. As a result, we recorded a $1.1 million restructuring charge, including $0.8 million that was incurred for the exited facility and $0.3 million related to the impairment of property and equipment and other long-term assets.

In August 2008, we implemented another restructuring plan to improve our operating cost structure. The cost reduction initiative
included a reduction-in-force that included terminating 20 employees. We completed this plan in October 2008. We provided severance pay, medical and other

related benefits to the employees terminated as a result of this restructuring plan. As a result of the August 2008 restructuring plan, we recorded a $0.2 million restructuring charge.

Impairment of Goodwill and Intangible Assets

The intangible assets associated with the acquisition of Arabella in 2007 were determined to be fully impaired as of March 31, 2009, as the core technology acquired will no longer be used in our ongoing
business operations and there are no future cash flows associated with this technology. We made a decision in March 2009 to cease use of the technology and do not have any plans to use it in future operations. As a result, an impairment charge of
$0.2 million was recorded in the first quarter of 2009.

We incurred impairment charges in 2008 for goodwill in the amount of $88.1
million and intangible assets in the amount of $25.1 million in connection with our annual impairment analysis conducted during the three months ended December 31, 2008. Goodwill was fully impaired due to the difference in fair value to
carrying value of equity being greater than the book value of goodwill. Intangibles were impaired for all of the recorded intangibles which resulted from the acquisitions of RF Magic, Vativ and Arabella. The discounted cash flow method was used to
estimate the remaining fair value of each intangible asset. The RF Magic developed technology asset was determined to be partially impaired and the developed technology did not have as long of an estimated useful life as originally anticipated.
Accordingly, the remaining useful life was reduced to two years and an impairment charge of $14.1 million was recorded. Additionally, the RF Magic customer relationships and trade names were determined to be fully impaired and an impairment charge
of $8.1 million and $0.5 million, respectively, was recorded. The Arabella developed technology asset was determined to be partially impaired and an impairment charge of $0.6 million was recorded. The Vativ developed technology was determined to be
fully impaired and an impairment charge of $1.8 million was recorded.

Other Income (expense), net

Other income (expense), net, which primarily consists of interest income, was consistent at approximately $0.1 million for 2010 and 2009.

Other income (expense), net, decreased by $0.1 million, from $0.2 million for 2008 to $0.1 million, for 2009 primarily due to lower
interest income resulting from lower interest rates in 2009 as compared to 2008.

Income Taxes

The income tax benefit of approximately $31.4 million for the fiscal year ended December 31, 2010, primarily represents the reversal of
our valuation allowance previously offsetting our Federal deferred tax assets (see Note 9 in the Consolidated Financial Statements). Income tax expense for 2009 and 2008 was related to foreign tax expenses.

Quarterly Financial Data (Unaudited)

The following table presents certain quarterly financial data for the eight consecutive quarters ended December 31, 2010. The unaudited quarterly information has been prepared on the same basis as the
audited consolidated financial statements and, in the opinion of management, includes all adjustments, consisting only of normal recurring adjustments, necessary for the fair presentation of this data. This information should be read in conjunction
with our consolidated financial statements and related notes thereto included elsewhere in this Annual Report. We believe that our quarterly revenue, particularly the mix of revenue components, and operating results are likely to vary in the future.
The operating results for any quarter are not necessarily indicative of the operating results for any future period or for any full year.

Liquidity and Capital Resources

As of
December 31, 2010, 2009 and 2008 we had cash, cash equivalents and investments of $168.8 million, $35.3 million and $34.4 million, respectively.

In October 2010, we completed a public offering in which 10,750,000 shares of our common stock were sold on our behalf at a price to the public of $9.70 per share, and which resulted in gross offering proceeds
of $104.3 million and net offering proceeds of approximately $99.3 million after deducting offering expenses paid by us.

As of
December 31, 2010, we had access to a $5.0 million revolving credit line under the terms of our Loan and Security Agreement, as amended, with SVB. We amended the provisions of our credit line in April 2010 and extended the term of the
credit line through April 8, 2011. The maximum credit available under the credit line was reduced from $10.0 million to $5.0 million. As amended, interest on the credit line is payable at an annual interest rate equal to the prime rate plus
0.5% if we maintain a liquidity ratio of at least 1.75 to 1, or the prime rate plus 2.0% if we maintain a liquidity ratio of less than 1.75 to 1. If any portion of the credit line remains unused at any time, we are required to pay a fee equal to
0.125% per annum of the average unused portion of the credit line so long as we maintain a liquidity ratio of at least 1.75 to 1, or 0.5% per annum of the average unused portion of the credit line when our liquidity ratio falls below 1.75
to 1. The credit line, as amended, also limits the

aggregate amount of assets and collateral that we are allowed to transfer to, and the amount of investments that we are allowed to make in, certain of our subsidiaries, to $600,000 per month. The
amount available under the credit line cannot exceed 80% of the value of our eligible accounts receivable and may be decreased by certain commitments, such as the $1.2 million and $35,000 standby letters of credit that secure our performance under
our San Diego, California, and San Jose, California, facility leases, respectively. As of December 31, 2010, the amount available under the credit line was reduced by the two standby letters of credit for our facility leases, and $3.8
million was available.

Cash Flows from Operating Activities

Net cash provided by operating activities in 2010 was $32.9 million, primarily resulting from net income of $64.7 million, an increase of $15.6 million in accounts payable and other liabilities, driven primarily by
an increase in inventory and compensation and benefit accruals, $10.5 million in stock compensation expenses and depreciation and amortization expense of $5.5 million. The increase in net cash was offset by a $31.6 million increase in our deferred
tax assets as a result of the reversal of the valuation allowance that was previously placed on these assets, $23.6 million increase in inventory primarily related to new deployments of our home networking products, an increase in our prepaid and
other assets of $5.4 million and an increase in accounts receivable of $2.8 million due to an increase in sales during 2010.

Net cash
provided by operating activities in 2009 was $1.3 million primarily resulting from a net loss of $13.2 million, an increase in accounts receivable of $1.6 million due to an increase of sales during the fourth quarter of 2009 and a decrease in other
liabilities of $0.5 million, offset by $9.3 million in stock compensation expenses, $5.1 million in depreciation and amortization expenses, including $1.6 million attributable to amortization of developed technology, and a $2.3 million decrease in
inventory as we sold the 2008 buildup of inventory in the first half of 2009.

Net cash provided by operating activities in 2008 was
$0.5 million. Although we had a net loss of $136.4 million, $123.2 million consisted of non-cash charges for impairment of goodwill and intangibles, amortization of developed technology and intangibles, inventory step-up and in-process research and
development. Additionally, the net loss included other non-cash charges for depreciation of $3.3 million and stock-based compensation of $13.5 million. The remaining change in operating cash flows was primarily due to a $11.2 million decrease in
accounts payable and accrued expenses and other current liabilities primarily due to lower inventory purchases late in 2008, a $3.3 million increase in inventory primarily due to our inventory build in preparation for the ramp of our channel
stacking switch product into the DIRECTV deployment, as well as from softness in demand for our MoCA products mainly related to our Verizon FiOS deployment, and a decrease in accounts receivable of $10.6 million, primarily driven by lower sales and
improved collections.

Cash Flows from Investing Activities

Net cash used in investing activities was $74.4 million in 2010 due to purchases of available-for-sale securities of $70.8 million and purchases of
property and equipment of $3.6 million, primarily consisting of research and development equipment.

Net cash provided by investing
activities was $2.2 million in 2009, consisting of maturities of short-term investments of $4.3 million offset by purchases of property and equipment of $2.1 million, consisting primarily of lab equipment.

Net cash provided by investing activities was $14.9 million in 2008, consisting of $6.1 million of net cash used in the acquisition of specified
Vativ assets in April 2008, purchases of property and equipment of $7.4 million primarily consisting of tenant improvements and equipment for our leased facilities in San Diego, California, and net purchases of short-term investments of $1.4
million.

Cash Flows from Financing Activities

Net cash provided by financing activities was $104.3 million in 2010, mainly due to the net proceeds of $99.3 million received from the public offering transaction that was completed in October 2010 and $5.0
million provided by the net proceeds from common stock purchases pursuant to stock option exercises and our ESPP.

Net cash provided by
financing activities was $1.7 million in 2009 provided by the net proceeds from common stock purchases pursuant to stock option exercises and our ESPP.

Net cash used in financing activities was $7.0 million in 2008, primarily driven by the payoff of outstanding debt in the amount of $8.9 million. This amount was offset by $2.2 million provided by the net proceeds
from warrant exercises and common stock purchases, primarily pursuant to our ESPP.

We believe that our cash, cash equivalents and
investments of $168.8 million as of December 31, 2010, together with the $3.8 million available to us under our existing credit line as of December 31, 2010, will be sufficient to fund our projected operating requirements for at
least the next 12 months.

We intend to continue spending substantial amounts in connection with the growth of our business and we may
need to obtain additional financing to pursue our business strategy, develop new products, respond to competition and market opportunities, and possibly acquire complementary businesses or technologies. On October 5, 2010, we completed a public
offering of 10,750,000 shares of our common stock, which resulted in net proceeds of approximately $99.3 million. In the future we may not be able to obtain such financing on favorable terms or at all. If we were to raise additional capital through
further sales of our equity securities, our stockholders would suffer dilution of their equity ownership. If we engage in debt financing, we may be required to accept terms that restrict our ability to incur additional indebtedness, prohibit us from
paying dividends, prohibit us from repurchasing our stock or making investments or force us to maintain specified liquidity or other ratios, any of which could harm our business, operating results and financial condition.

Off-Balance Sheet Arrangements

During the periods presented, we did not have, nor do we currently have, any relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special
purpose entities, which would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes.



|Item 7A. | Quantitative and Qualitative Disclosures About Market Risk
|-------- | ----------------------------------------------------------

Foreign Currency Risk

Our sales have been historically denominated in U.S. dollars and
an increase in the value of U.S. dollar relative to the currencies of the countries in which our customers operate could materially affect the demand of our products by non-U.S. customers, leading to a reduction in orders placed by these customers,
which would adversely affect our business. Our international sales and marketing operations incur expenses that are denominated in foreign currencies. These expenses could be materially affected by currency fluctuations; however, we do not consider
this currency risk to be material as the related costs do not constitute a significant portion of our total spending. We outsource our wafer manufacturing, assembly, testing, warehousing and shipping operations; however all expenses related thereto
are denominated in U.S. dollars. If the value of the U.S. dollar decreases relative to the currencies of the countries in which such contractors operate, the prices we are charged for their services may increase, which would adversely affect our
business. Currently, we have not implemented any hedging strategies to mitigate risks related to the impact of fluctuations in currency exchange rates.

Interest Rate Risk

We typically
maintain an investment portfolio of various holdings, types and maturities. We do not use derivative financial instruments. We place our cash investments in deposits and money market funds with major financial institutions, U.S. government
obligations and debt securities of corporations with strong credit ratings in a variety of industries that meet high credit quality standards, as specified in our investment policy guidelines. These guidelines also limit the amount of credit
exposure to any one issue, issuer or type of instrument.

All of our fixed income investments are classified as available-for-sale and
therefore reported on the balance sheet at market value. The fair value of our cash equivalents and investments are subject to change as a result of changes in market interest rates and investment risk related to the issuers credit worthiness.
We do not utilize financial contracts to manage our exposure in our investment portfolio to changes in interest rates. We place our cash investments in instruments that meet credit quality standards, as specified in our investment policy guidelines.
We have established guidelines

relative to diversification and maturities that attempt to maintain safety and liquidity. These guidelines are periodically reviewed and modified to take advantage of interest rate trends. We
generally do not utilize derivatives to hedge against increases in interest rates which decrease market values.

At
December 31, 2010, we had $168.8 million in cash, cash equivalents and investments, all of which are stated at fair value. A 100 basis point increase or decrease in market interest rates over a three month period would not be expected to
have a material impact on the fair value of the $98.1 million of cash and cash equivalents held as of December 31, 2010, as these consisted of securities with maturities of less than three months. A 100 basis point increase or decrease in
interest rates would, however, decrease or increase, respectively, the fair value of the $70.7 million of our investments by approximately $0.6 million.

The financial statements and supplementary data required by this item are included in Part IV, Item 15, Exhibits and Financial
Statement Schedules of this Annual Report.

|Item 9A. | Controls and Procedures
|-------- | -----------------------

Conclusion
Regarding the Effectiveness of Disclosure Controls and Procedures

We maintain disclosure controls and procedures that are designed
to ensure that information required to be disclosed in our periodic reports filed with the SEC are recorded, processed, summarized and reported within the time periods specified in the SECs rules and forms and that such information is
accumulated and communicated to our management, including our chief executive officer and chief financial officer, as appropriate, to allow for timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and
procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and no evaluation of controls and procedures can provide
absolute assurance that all control issues and instances of fraud, if any, within a company have been detected. Management is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

As required by Rule 13a-15(b) of the Exchange Act, prior to filing this Annual Report, we carried out an evaluation, under the supervision and with
the participation of our management, including our chief executive officer and chief financial officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the
Exchange Act) as of the end of the period covered by this Annual Report. Based on their evaluation, our chief executive officer and chief financial officer concluded that our disclosure controls and procedures were effective at the reasonable
assurance level as of the end of the period covered by this Annual Report.

Managements Report on Internal Control over Financial Reporting

The management of Entropic is responsible for establishing and maintaining adequate internal control over financial reporting, as
such term is defined in Rule 13a-15(f) of the Exchange Act. Under the supervision and with the participation of our management, including our chief executive officer

##### Table of Contents

and chief financial officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework set forth in Internal Control-Integrated
Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on our evaluation under the framework set forth in Internal Control-Integrated Framework, our management concluded that our internal control
over financial reporting was effective as of December 31, 2010. Ernst & Young LLP, the independent registered public accounting firm that audited the financial statements included in this Annual Report, has issued an attestation report
on our internal control over financial reporting as of December 31, 2010, which is included herein.

Changes in Internal Control over Financial
Reporting

An evaluation was also performed under the supervision and with the participation of our management, including our chief
executive officer and chief financial officer, of any change in our internal control over financial reporting that occurred during the fourth quarter of 2010 and that has materially affected, or is reasonably likely to materially affect, our
internal control over financial reporting. That evaluation did not identify any change in our internal control over financial reporting that occurred during the fourth quarter of 2010 that has materially affected, or is reasonably likely to
materially affect, our internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Stockholders

Entropic Communications,
Inc.

We have audited Entropic Communications, Inc.s internal control over financial reporting as of December 31, 2010,
based on criteria established in Internal ControlIntegrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO criteria). Entropic Communications, Inc.s management is responsible for
maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Managements Report on Internal Control over Financial
Reporting. Our responsibility is to express an opinion on the companys internal control over financial reporting based on our audit.

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

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

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

In our opinion, Entropic Communications, Inc. maintained, in all material respects, effective
internal control over financial reporting as of December 31, 2010, based on the COSO criteria.

We also have audited, in
accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Entropic Communications, Inc. as of December 31, 2010 and 2009, and the related consolidated statements of
operations, stockholders equity and comprehensive income (loss) and cash flows for each of the three years in the period ended December 31, 2010 and our report dated February 3, 2011 expressed an unqualified opinion thereon.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Stockholders

Entropic Communications,
Inc.

We have audited the accompanying consolidated balance sheets of Entropic Communications, Inc. as of December 31, 2010 and
2009, and the related consolidated statements of operations, stockholders equity and comprehensive income (loss), and cash flows for each of the three years in the period ended December 31, 2010. Our audits also included the
financial statement schedule listed in the Index at Item 15(a)2. These financial statements and schedule are the responsibility of the Companys management. Our responsibility is to express an opinion on these financial statements and
schedule based on our audits.

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

In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of Entropic Communications, Inc. at December 31, 2010 and 2009, and the consolidated results of its operations and its cash flows for each of the three years in the period ended
December 31, 2010 in conformity with U.S. generally accepted accounting principles. Also, in our opinion, the related financial statement schedule, when considered in relation to the basic financial statements taken as a whole, presents
fairly in all material respects the information set for therein.

We also have audited, in accordance with the standards of the Public
Company Accounting Oversight Board (United States), Entropic Communications, Inc.s internal control over financial reporting as of December 31, 2010, based on criteria established in Internal ControlIntegrated Framework issued

Entropic Communications, Inc.

Notes to Consolidated Financial Statements

1. Organization and Summary of Significant Accounting Policies

Business

Entropic Communications, Inc. was organized under the laws of the state of Delaware
on January 31, 2001.

We are a fabless semiconductor company that designs, develops and markets systems solutions to enable
connected home entertainment. Our technologies change the way high-definition television-quality video, or HD video, and standard-definition television-quality video, or SD video, and other multimedia content such as movies, music and photos are
brought into and delivered throughout the home.

Basis of Presentation

The accompanying audited consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles, or GAAP.

The accompanying audited consolidated financial statements include our accounts and those of our wholly-owned subsidiaries. All inter-company
accounts and transactions have been eliminated in consolidation.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts
reported in the consolidated financial statements and these accompanying notes. Among the significant estimates affecting the consolidated financial statements are those related to business combinations, revenue recognition, allowance for doubtful
accounts, inventory reserves, long-lived assets (including intangible assets), warranty reserves, accrued bonuses, income taxes, valuation of equity securities and stock-based compensation. On an ongoing basis, management reviews its estimates based
upon currently available information. Actual results could differ materially from those estimates.

Foreign Currency Translation

The functional currency for our foreign subsidiaries is the local currency. Assets and liabilities denominated in foreign currencies are translated
using the exchange rates on the balance sheet dates. Net revenues and expenses are translated using the average exchange rates prevailing during the year. Any translation adjustments resulting from this process are shown separately as a component of
accumulated other comprehensive income (loss) within stockholders equity in the consolidated balance sheets. Foreign currency transaction gains and losses are reported in operating expenses, net in the consolidated statements of operations.

Revenue Recognition

Our net
revenues are generated principally by sales of our semiconductor products. During the years ended December 31, 2010, 2009 and 2008, product net revenues represented more than 99% of our total net revenues.

##### Table of Contents

Our sales primarily occur through the efforts of our direct sales force. The remainder of our sales
occurs through third-party sales representatives and distributors. During the years ended December 31, 2010, 2009 and 2008, more than 99% of our sales occurred through the efforts of our direct sales force.

We recognize product revenues when the following fundamental criteria are met: (i) persuasive evidence of an arrangement exists,
(ii) delivery has occurred or services have been rendered, (iii) the price to the customer is fixed or determinable and (iv) collection of the resulting receivable is reasonably assured. These criteria are usually met at the time of
product shipment; however, we do not recognize revenue until all substantive customer acceptance requirements have been met, when applicable.

A portion of our sales is made through distributors, agents or customers acting as agents under agreements allowing for pricing credits and/or rights of return. Product net revenues on sales made through these
distributors are not recognized until the distributors ship the product to their customers.

Revenues derived from billing customers for
shipping and handling costs are classified as a component of net revenues. Costs of shipping and handling charged by suppliers are classified as a component of cost of net revenues.

We record reductions to net revenues for estimated product returns and pricing adjustments, such as competitive pricing programs, in the same
period that the related revenue is recorded. The amount of these reductions is based on historical sales returns and other factors known at the time. If actual returns differ significantly from our estimates, such differences would be recorded in
our results of operations for the period in which the actual returns become known. To date, changes in estimated returns have not been material to net revenues in any related period.

We are party to an inventory hubbing agreement with Motorola. Pursuant to this agreement, we deliver products to the designated
third-party warehouse based upon the customers projected needs, but do not recognize product revenue unless and until the customer removes our products from the third-party warehouse to incorporate into its own products.

We receive royalties in exchange for an exclusive right to manufacture and sell certain products. We have determined that we are not able to
reliably estimate the royalties earned in the period the sales occur and, as a result, we record net revenues based on cash receipts. The royalty revenues recorded during the years ended December 31, 2010, 2009 and 2008 were $1.2 million,
$1.9 million and $2.9 million, respectively, and are included in net revenues in the accompanying consolidated statements of operations.

We have entered into agreements to license certain hardware and software, also referred to as the nodes, to certain members of the
Multimedia over Coax Alliance, or MoCA, for a period of three years and to provide upgrades when and if they become available. The agreements limit the rights to use the nodes to test compliance of the members own products to the MoCA
specification. For these arrangements, we defer all of the license revenues when the nodes are delivered and recognized the revenues on a straight-line basis over the three-year term of the agreement.

We provide rebates on our products to certain customers. At the time of the sale, we accrue 100% of the potential rebate as a reduction to net
revenue and do not apply a breakage factor. The amount of these reductions is based upon the terms included in various rebate agreements. We reverse the accrual for unclaimed rebate amounts as specific rebate programs contractually end or when we
believe unclaimed rebates are no longer subject to payment and will not be paid. For the years ended December 31, 2010, 2009 and 2008, we reduced net revenue by $0.6 million, $0.7 million and $0.8 million, respectively, in connection with
our rebate programs.

##### Table of Contents

We occasionally enter into agreements where revenue is derived from multiple deliverables including
any mix of products and/or services. These products and/or services are generally delivered from approximately three months to two years after the execution date. Revenue recognition for agreements with multiple deliverables is based on the
individual units of accounting determined to exist in the agreement. A delivered item is considered a separate unit of accounting when the delivered item has value to the customer on a stand-alone basis. Items are considered to have stand-alone
value when they are sold separately by any vendor or when the customer could resell the item on a stand-alone basis.

For multiple
deliverable agreements entered into after December 31, 2009, consideration is allocated at the inception of the agreement to all deliverables based on their relative selling price. The relative selling price for each deliverable is determined
using vendor specific objective evidence, or VSOE, of selling price or third-party evidence of selling price if VSOE does not exist. If neither VSOE nor third-party evidence of selling price exists, we use our best estimate of the selling price for
the deliverable. To date, multiple deliverable contacts have not been material to net revenues in any related period and our adoption of the new accounting guidance for determining multiple element arrangements effective January 1, 2010 did not
have an impact on our operating results.

For multiple deliverable agreements entered into on or prior to December 31, 2009,
consideration was generally allocated to each unit of accounting based upon its relative fair value when objective and reliable evidence of fair value existed for all units of accounting in the agreement. The fair value of an item was generally the
price charged for the product, if the item was regularly sold on a stand-alone basis.

In order to establish VSOE of selling price, we
must regularly sell the product and/or service on a standalone basis with a substantial majority priced within a relatively narrow range. VSOE of selling price is usually the midpoint of that range. If there is not a sufficient number of standalone
sales and VSOE of selling price cannot be determined, then we consider whether third-party evidence can be used to establish the selling price. If neither VSOE nor third-party evidence of selling price exists, effective January 1, 2010 we
determine our best estimate of selling price using average selling prices over a rolling 12-month period as well as market conditions. If the product or service has no history of sales, we rely upon sales prices set by our pricing committee,
adjusted for applicable discounts.

We recognize revenue for delivered elements only when we determine there are no uncertainties
regarding customer acceptance. Changes in the allocation of the sales price between delivered and undelivered elements can impact the revenue recognition but do not change the total revenue recognized on any agreement.

Concentration of Credit Risk

Financial
instruments that potentially subject us to concentration of credit risk consist primarily of cash and cash equivalents, marketable securities, accounts receivable, leases payable and lines of credit. Our policy is to place our cash, cash equivalents
and marketable securities with high quality financial institutions in order to limit our credit exposure. We extend credit to certain of our customers based on an evaluation of the customers financial condition and a cash deposit is generally
not required. We estimate potential losses on trade receivables on an ongoing basis.

We invest cash in deposits and money market funds
with major financial institutions, U.S. government obligations and debt securities of corporations with investment grade credit ratings in a variety of industries. It is our policy to invest in instruments that have a final maturity of no
longer than two years, and to maintain a portfolio weighted average maturity of no longer than 12 months.

##### Table of Contents

Cash and Cash Equivalents

Cash and cash equivalents consist of cash, money market funds, commercial paper and corporate bonds. We consider all highly liquid investments with a maturity of three months or less from the date of purchase that
are readily convertible into cash to be cash equivalents.

Marketable Securities

We account for marketable securities by determining the appropriate classification of such securities at the time of purchase and reevaluating such
classification as of each balance sheet date. As of December 31, 2010, all marketable securities were classified as available-for-sale. Cash equivalents and marketable securities are reported at fair value with the related unrealized gains
and losses included in accumulated other comprehensive income (loss), a component of stockholders equity, net of tax. The investments are adjusted for amortization of premiums and discounts to maturity and such amortization is included in
interest income. Realized gains and losses and declines in value judged to be other than temporary are determined based on the specific identification method and are reported in the consolidated statements of operations.

Fair Value of Financial Instruments

The
carrying amounts of cash equivalents, marketable securities, trade receivables, accounts payable and other accrued liabilities approximate their fair value due to the relative short-term maturities. The fair value of marketable securities is
determined using quoted market price for those securities. The carrying amounts of our capital lease obligations, loans payable and other long-term liabilities approximate their fair value. The fair value of capital lease obligations and loans
payable was estimated based on the current interest rates available to us for debt instruments with similar terms, degrees of risk and remaining maturities.

Allowance for Doubtful Accounts

We evaluate the collectability of accounts receivable based on
a combination of factors. In cases where we are aware of circumstances that may impair a specific customers ability to meet its financial obligations subsequent to the original sale, we will record a specific allowance against amounts due, and
thereby reduce the net recognized receivable to the amount we reasonably believe will be collected. For all other customers, we recognize allowances for doubtful accounts based upon specific identification, industry and geographic concentrations,
the current business environment and our historical experience. We did not record an allowance for doubtful accounts as of December 31, 2010 and 2009.

Inventories

Inventories are stated at the lower of cost (first-in, first-out) or market. Lower
of cost or market adjustments reduce the carrying value of the related inventory and take into consideration reductions in sales prices, excess inventory levels and obsolete inventory. These adjustments are calculated on a part-by-part basis and, in
general, represent excess inventory value on hand compared to 12-month demand projections. Once established, these adjustments are considered permanent and are not reversed until the related inventory is sold or disposed.

We have entered into a capacity agreement with one of our third-party foundry contractors in order to guarantee minimum capacity volumes on our
digital outdoor unit and silicon tuner products. Pursuant to the capacity agreement, we have made prepayments which will result in reduced prices paid on future inventory purchases up to a specified volume. The prepayments are being amortized into
the cost of our inventory purchases based on the specified volume commitments under the terms of the capacity agreement. The prepaid inventory volume commitments are assessed for impairment on a periodic basis by comparing the remaining prepaid
balance to our estimate of remaining purchases. There have been no impairments to date.

##### Table of Contents

Property and Equipment

Property and equipment are stated at cost and are depreciated using the straight-line method over the estimated useful lives of the assets (three to seven years), except leasehold improvements and software
which are amortized over the lesser of the estimated useful lives of the asset or the remaining lease/license term.

Goodwill and Intangible Assets

We record goodwill and other intangible assets based on the fair value of the assets acquired. In determining the fair value of the
assets acquired, we utilize extensive accounting estimates and judgments to allocate the purchase price to the fair value of the net tangible and intangible assets acquired. We use the discounted cash flow method to estimate the value of intangible
assets acquired. The estimates used to value and amortize intangible assets are consistent with the plans and estimates that we use to manage our business and are based on available historical information and industry estimates and averages.

We assess goodwill and certain intangible assets for impairment using fair value measurement techniques on an annual basis, during the
fourth quarter of the year or more frequently if indicators of impairment exist. We perform an interim goodwill impairment test when it is more likely than not that the fair value of a reporting unit is less than the carrying amount. We operate as
one reporting unit. The goodwill impairment test compares the implied fair value of the reporting units goodwill with the carrying amount of that goodwill to measure the amount of the impairment loss, if any. The implied fair value of goodwill
is determined in the same manner as in a business combination. Determining the fair value of the implied goodwill is judgmental in nature and often involves the use of significant estimates and assumptions. These estimates and assumptions could have
a significant impact on whether or not an impairment charge is recognized and also the magnitude of any such charge. Estimates of fair value are primarily determined using discounted cash flows and market comparisons. These approaches use
significant estimates and assumptions, including the size and timing of deployments by our customers and related projections and timing of future cash flows, discount rates reflecting the risk inherent in future cash flows, perpetual growth rates,
stage of products in development, determination of appropriate market comparables, and determination of whether a premium or discount should be applied to comparables.

Warranty Accrual

We generally provide a warranty on our products for a period of one year;
however, it may be longer for certain customers. Accordingly, we establish provisions for estimated product warranty costs at the time revenue is recognized based upon our historical activity and, additionally, for any known product warranty issues.
Warranty provisions are recorded as a cost of net revenues. The determination of such provisions requires us to make estimates of product return rates and expected costs to replace or rework the products under warranty. When the actual product
failure rates, cost of replacements and rework costs differ from our estimates, revisions to the estimated warranty accrual are made. Actual claims are charged against the warranty reserve.

Guarantees and Indemnifications

In the ordinary course of business, we have entered into
agreements with customers that include indemnity provisions. To date, there have been no known events or circumstances that have resulted in any significant costs related to these indemnification provisions and, as a result, no liabilities have been
recorded in the accompanying financial statements.

Software Development Costs

Software development costs are capitalized beginning when technological feasibility has been established and ending when a product is available for sale to customers. To date, the period between achieving
technological feasibility and when the software is made available for sale to customers has been relatively short and software development costs qualifying for capitalization have not been significant. As such, all software development costs have
been expensed as incurred in research and development expense.

Income Taxes

We estimate income taxes based on the various jurisdictions where we conduct business. Significant judgment is required in determining our worldwide
income tax provision. We estimate the current tax liability and assess temporary differences that result from differing treatments of certain items for tax and accounting purposes. These differences result in deferred tax assets and liabilities,
which are reflected in our balance sheets. We then assess the likelihood that deferred tax assets will be realized. A valuation allowance is recorded when it is more likely than not that some of the deferred tax assets will not be realized. When a
valuation allowance is established or increased, we record a corresponding tax expense in our statements of operations. We review the need for a valuation allowance each interim period to reflect uncertainties about whether we will be able to
utilize deferred tax assets before they expire. The valuation allowance analysis is based on estimates of taxable income for the jurisdictions in which we operate and the periods over which our deferred tax assets will be realizable.

We recognize and measure benefits for uncertain tax positions using a two-step approach. 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 the tax position will be sustained upon audit, including resolution of any related appeals or litigation
processes. For tax positions that are more likely than not of being sustained upon audit, the second step is to measure the tax benefit as the largest amount that has more than a 50% chance of being realized upon settlement. Significant judgment is
required to evaluate uncertain tax positions. We evaluate uncertain tax positions on a quarterly basis. The evaluations are based upon a number of factors, including changes in facts or circumstances, changes in tax law, correspondence with tax
authorities during the course of audits and effective settlement of audit issues.

In assessing the realizability of deferred tax
assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during
the periods in which those temporary differences become deductible. During the fourth quarter of 2010 we concluded that it was more likely than not that we would be able to realize the benefit of our federal deferred tax assets in the future. We
based this conclusion on historical and projected operating performance, as well as our expectation that our operations will generate sufficient taxable income in future periods to realize the tax benefits associated with the deferred tax assets. As
a result, we reduced our valuation allowance on our net deferred tax assets by $31.6 million at December 31, 2010. We will continue to assess the need for a valuation allowance on the deferred tax asset by evaluating both positive and
negative evidence that may exist. Any adjustment to the net deferred tax asset valuation allowance would be recorded in the income statement for the period that the adjustment is determined to be required.

Stock-Based Compensation

We have equity
incentive plans under which incentive stock options have been granted to employees and restricted stock units and non-qualified stock options have been granted to employees and non-employees. We also have an employee stock purchase plan for all
eligible employees.



F-11



---

##### Table of Contents

Our stock-based compensation cost is measured at the grant date, based on the estimated fair value of
the award, and is recognized as an expense over the employees requisite service period. We have no stock-based compensation awards with market or performance conditions. The stock-based compensation expense attributable to awards under our
2007 Employee Stock Purchase Plan, or ESPP, was determined using the Black-Scholes option pricing model.

We also grant awards to
non-employees and determine the fair value of such stock-based compensation awards granted as either the fair value of the consideration received or the fair value of the equity instruments issued, whichever is more reliably measurable. If the fair
value of the equity instruments issued is used, it is measured using the stock price and other measurement assumptions as of the earlier of (i) the date at which a commitment for performance by the counterparty to earn the equity instruments is
reached, or (ii) the date at which the counterpartys performance is completed.

We recognize excess tax benefits associated
with stock-based compensation to stockholders equity only when realized. When assessing whether excess tax benefits relating to stock-based compensation have been realized, we follow the with and without approach excluding any
indirect effects to be realized until after the utilization of all other tax benefits available to us.

Segment Reporting

We are organized as, and operate in, one reportable segment: the design, development and sale of silicon integrated circuits. Products within this
segment are embedded in electronic devices used to enable the delivery of multiple streams of HD video and other multimedia content for entertainment purposes into and throughout the home. Our chief operating decision maker is our chief executive
officer, or CEO. Our CEO reviews financial information presented on a consolidated basis for the purpose of evaluating financial performance and allocating resources. There are no segment managers who are held accountable for operations below the
consolidated financial statement level. Our assets are primarily located in the United States and not allocated to any specific region. Therefore, geographic information is presented only for total revenue.

Recently Issued Accounting Standards

In
October 2009, the Financial Accounting Standards Board, or FASB, issued authoritative guidance for arrangements with multiple deliverables. The guidance will allow companies to allocate arrangement consideration in multiple deliverable arrangements
in a manner that is intended to better reflect the transactions economics. The guidance also removes non-software components of tangible products and certain software components of tangible products from the scope of existing software revenue
guidance. The new guidance requires expanded qualitative and quantitative disclosures and is effective for fiscal years beginning on or after June 15, 2010. Early adoption of the guidance is permitted. We have adopted this guidance effective
January 1, 2010 and the application of this guidance did not have a material impact on our consolidated financial statements.

In
March 2010, the FASB ratified the milestone method of revenue recognition. Under this new standard, an entity can recognize contingent consideration earned from the achievement of a substantive milestone in its entirety in the period in which the
milestone is achieved. A milestone is defined as an event (i) that can only be achieved based in whole or in part on either the entitys performance or on the occurrence of a specific outcome resulting from the entitys performance,
(ii) for which there is substantive uncertainty at the date the arrangement is entered into that the event will be achieved, and (iii) that would result in additional payments being due to the entity. The milestone method of revenue
recognition is effective for fiscal years beginning on or after June 15, 2010 and may be applied prospectively after the adoption date or retrospectively for all periods presented. The impact of adoption on our consolidated financial statements
will ultimately depend on the terms of any future business transactions.

Fair Value of Financial Instruments

We hold certain financial assets, including cash equivalents and marketable securities that are required to be measured at fair value on a recurring basis. Cash equivalents include money market funds, commercial
paper and corporate bonds and are carried at fair value. Marketable securities are carried at fair value.

We use a three-tier fair
value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include: Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active
markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions.

Our deferred compensation liability represents bonus compensation to be paid out in the event that our stock price
does not reach a guaranteed level in connection with certain stock options granted. The fair value of this liability is remeasured quarterly using the Black Scholes option pricing model which considers the potential payout, the remaining time until
payout, volatility of the underlying shares, and the risk-free interest rate to calculate the liability that may be due under the arrangement.

The change in liability for the years ended December 31, 2010, 2009 and 2008 is included in compensation expense as follows (in thousands):

Accrued Bonuses

We maintained a discretionary management bonus plan in 2010 and 2009. The potential bonus payments made under each of these plans are based
significantly on the achievement of operational, financial and business development objectives for the calendar year. As of December 31, 2010, we had exceeded all of our performance targets specified by the 2010 bonus

plan. We incurred $3.9 million in management bonuses for the year ended December 31, 2010, of which $1.5 million was paid during the year. As of December 31, 2009, some but
not all of the performance targets specified by the 2009 bonus plan had been achieved. We accrued $0.8 million in management bonuses for the year ended December 31, 2009. Any actual bonus amounts awarded will be at the discretion of the
compensation committee of our board of directors and in accordance with the terms of the plan.

In addition to the 2010 and 2009
management bonus plans, we also accrued for a discretionary bonus pool in the amount of $0.3 million and $0.2 million as of December 31, 2010 and 2009, respectively. These bonus pools were approved by the compensation committee of our
board of directors. No specific criteria were established by the compensation committee for awards under this bonus pool and the amount and timing of individual awards to eligible employees will be made at the discretion of the compensation
committee or the individuals to whom the committee delegates its authority.

Restructuring Activity

We incurred restructuring charges totaling $2.2 million in 2009 pursuant to a restructuring plan we implemented in March 2009 that resulted in a
worldwide reduction-in-force of 55 employees and the closure of our Nice, France and Kfar Saba, Israel offices. All of the terminated employees received severance payments upon their effective termination. In addition, the affected French and
Israeli employees continued to receive salaries until their termination became effective upon the expiration of applicable contractual or statutory notice periods.

We believe that the continued payment of salaries to the terminated Nice and Kfar Saba employees during their respective notice periods represented a one-time termination benefit since we were required by contract
or law to make these payments whether or not these employees continued to work for us through their actual termination date. We also recorded restructuring charges relating to the termination of operating leases and other contract costs in the
period in which we ceased to exercise the rights conveyed to us by the applicable contract.

The following table presents a rollforward
of our restructuring liability as of December 31, 2010 and 2009, which is included within accrued payroll and benefits in the consolidated balance sheets (in thousands):

The intangible assets associated with the acquisition of Arabella Software Ltd., or Arabella, in 2007 were determined
to be fully impaired as of March 31, 2009, as the core technology acquired would no longer be used in our ongoing business operations and there would be no future cash flows

associated with this technology. We made a decision in March 2009 to cease use of the technology and do not have any plans to use it in future operations. As a result, an impairment charge of
$0.2 million was recorded in the first quarter of 2009.

In August 2008, we implemented a restructuring plan to improve our operating
cost structure. We provided severance pay and other related benefits to the employees terminated as a result of this restructuring plan. We recorded a $0.2 million restructuring charge related to this plan.

In February 2008, we implemented a restructuring plan to exit the operating lease for our former corporate headquarters in San Diego, California.
We recorded a $1.1 million restructuring charge, including $0.8 million for the exited facility and $0.3 million related to the impairment of property and equipment and other long-term assets.

Purchase Commitments

We had firm purchase order commitments for the acquisition of inventory as of December 31, 2010 and 2009 of $26.0 million and $20.2 million, respectively.

Net Income (Loss) Per Common Share

We
compute basic income (loss) per share of common stock by dividing net income (loss) by the weighted average number of shares of common stock outstanding for the period. Diluted income (loss) per share is computed using the weighted average number of
shares of common stock and dilutive common equivalent shares outstanding for the period. Common equivalent shares from stock options and other common stock equivalents are excluded from the computation when their effect is antidilutive.

3. Acquisitions

On April 3, 2008, we acquired certain specified assets of Vativ Technologies, Inc., or Vativ, including Vativs intellectual property
rights, existing product lines, inventory and equipment. Vativ, a fabless semiconductor company based in San Diego, California, focused on providing high-bandwidth, advanced digital signal processing solutions for digital television and 10 gigabit
Ethernet markets. We paid $5.9 million in cash for the acquired assets. The results of operations of Vativ have been included in our results of operations from the date of acquisition.

The acquired assets did not include Vativs cash, cash equivalents, investments or any portion of Vativs accounts receivable. We assumed
certain liabilities of Vativ equal to $0.3 million, including current accounts payable and accrued vacation liabilities for the former employees of Vativ we hired. In addition, we committed to pay cash retention bonuses in the aggregate amount of
$0.7 million to employees hired from Vativ in connection with the acquisition earned over the first 90 days of employment. The retention bonuses were recorded as expense during the service period and were not included in the assumed liabilities. In
July 2008 and January 2009, we paid $0.6 million and $0.1 million, respectively, for these retention bonuses.

##### Table of Contents

We accounted for the acquisition of Vativ by the purchase method of accounting and, as such, the
assets acquired and liabilities assumed have been recorded at fair value. The excess of the purchase price over the fair value of net assets acquired was allocated to goodwill. The allocation of the purchase price for acquisitions requires extensive
use of accounting estimates and judgments to allocate the purchase price to the identifiable tangible and intangible assets acquired and liabilities assumed based on their respective fair values. We determined the estimated fair values of in-process
research and development, identifiable intangible assets and certain tangible assets of the acquisition based on information available at the time of the acquisition. Such valuations require significant estimates and assumptions including but not
limited to: determining the timing and estimated costs to complete the in-process projects, estimating future cash flows and developing appropriate discount rates.

The following table summarizes the components of the purchase price (in thousands):

The acquisition was funded from our cash and cash equivalents balances.

These identifiable intangible assets were being amortized on a straight-line basis.

The developed technology represents proprietary knowledge that was technologically feasible as of the valuation date and includes all fully
functioning products at the date of the valuation. The amount assigned to the developed technology was assigned based on the estimated net discounted cash flows from the related product lines on the date of acquisition. In connection with our annual

##### Table of Contents

impairment test of goodwill and intangible assets conducted in the fourth quarter of 2008, we determined the developed technology and customer relationships were fully impaired as a result of
continuing market declines and low customer acceptance of this technology. An impairment charge was recorded in the fourth quarter of 2008 for the development technology and customer relations in the amount of $1.8 million and $30,000, respectively
(see Notes 1 and 4).

The in-process research and development, or IPR&D, acquired at the date of acquisition relates to Vativs
High Definition Multimedia Interface switch product. The amount was expensed on the acquisition date because the acquired technology had not yet reached technological feasibility and had no alternative future uses. A discounted cash flow approach
was utilized in valuing the IPR&D. The value of the technology was the sum of the present value of projected debt-free net income, in excess of returns on requisite assets, over the economic life of the IPR&D.

4. Goodwill and Intangible Assets

In conjunction with our March 2009 restructuring plan, we determined that the intangible assets associated with the acquisition of Arabella in 2007
were fully impaired, as the core technology acquired would no longer be used in our ongoing business operations and there would be no future cash flows associated with this technology. As a result, an impairment charge of $0.2 million was recorded
in 2009.

The rollforward of intangible assets is as follows (in thousands):

5. Credit Facilities

As of December 31, 2010, we had access to a $5.0 million revolving credit line under the terms of our Loan and Security Agreement, as amended, with Silicon Valley Bank, or SVB. We amended the provisions
of our credit line in April 2010 upon the payment of a $12,500 amendment fee and extended the term of the credit line through April 8, 2011. The maximum credit available under the credit line was reduced from $10.0 million to $5.0 million. As
amended, interest on the credit line is payable at an annual interest rate equal to the prime rate plus 0.5% if we maintain a liquidity ratio of at least 1.75 to 1, or the prime rate plus 2.0% if we maintain a liquidity ratio of less than 1.75 to 1.
If any portion of the credit line remains unused at any time, we are required to pay a fee equal to 0.125% per annum of the average unused portion of the credit line so long as we maintain a liquidity ratio of at least 1.75 to 1, or
0.5% per annum of the average unused portion of the credit line when our liquidity ratio falls below 1.75 to 1. The credit line, as amended, also limits the aggregate amount of assets and collateral that we are allowed to transfer to, and the
amount of investments that we are allowed to make in, certain of our subsidiaries to $600,000 per month. The amount available under the credit line cannot exceed 80% of the value of our eligible accounts receivable and may be decreased by certain
commitments, such as the $1.2 million and $35,000 standby letters of credit that secure our performance under our San Diego, California, and San Jose, California, facility leases, respectively.

As of December 31, 2010, $3.8 million was available under the credit line. The amount available under the credit line was reduced by the
two standby letters of credit for our facility leases.

6. Commitments and Contingencies

We have multiple operating leases for facilities and software license agreements expiring through 2015. As of December 31, 2010, we have
no outstanding capital leases that have initial terms of more than one year.

The minimum future payments under all noncancellable
operating leases with an initial term of one year or more as of December 31, 2010 are as follows (in thousands):

million, respectively.

From time to time, we may be involved in litigation relating to claims arising out of our operations. We are not
a party to any legal proceedings that are expected, individually or in the aggregate, to have a material adverse effect on its business, financial condition or operating results.

7. Preferred Stock Warrant Liabilities

In connection with the loan and security agreement entered into with SVB in May 2005, we issued a warrant to SVB to purchase 579,000 shares of our Series B redeemable convertible preferred stock. In 2008, we issued
101,000 shares of our common stock in connection with warrant exercises and no warrants were outstanding at December 31, 2010.

8.
Stockholders Equity

Common Stock

On October 5, 2010, we completed a public offering in which 10,750,000 shares of our common stock were sold on our behalf at a price to the public of $9.70 per share, and which resulted in gross offering
proceeds of $104.3 million and net offering proceeds of approximately $99.3 million after deducting the offering expenses.

Preferred Stock

We are authorized to issue 10,000,000 shares of undesignated preferred stock at $0.001 par value per share. Our board of directors
may determine the rights, preferences, privileges, qualifications, limitations and restrictions granted or imposed upon any series of preferred stock. As of December 31, 2010, no preferred stock was outstanding.

Equity Incentive Plans

We have in effect
equity compensation plans under which incentive stock options, non-qualified stock options and restricted stock units have been granted to employees, directors and consultants to purchase shares of our common stock at a price not less than the fair
market value of the stock at the date of grant except in the event of a business combination.

2007 Equity Incentive Plan

Our 2007 Equity Incentive Plan, or the 2007 Plan, became effective upon the execution of the underwriting agreement in connection with our initial
public offering and replaced our 2001 Stock Option Plan, or the 2001 Plan. The 2007 Plan provides for the grant of incentive and non-statutory stock options, restricted stock awards, restricted stock unit awards, stock appreciation rights,
performance stock awards and other forms of equity compensation, or collectively Stock Awards. As of December 31, 2010, there were 16,798,000 shares of common stock reserved under the 2007 Plan. This share amount is automatically
increased by the amount equal to the number of shares subject to any outstanding option under the 2001 Plan that expires or is forfeited following the date that the 2007 Plan became effective. In addition, the share reserve will automatically
increase on January 1 of each year through 2017 by the lesser of 5% of the total number of shares of common stock outstanding on December 31 of the preceding calendar year, 7,692,000 shares of common stock, or a lesser amount of shares of
common stock to be determined by the board of directors prior to the first day of the calendar year. Our board of directors may amend or terminate the 2007 Plan at any time. Generally, options outstanding vest over periods not exceeding four years
and are exercisable for up to ten years from the grant date. In January 2011, 4,255,000 shares of common stock, which was 5% of the outstanding shares of common stock as of December 31, 2010, were added to the 2007 Plan.

2007 Non-Employee Directors Plan

Our 2007 Non-Employee Directors Plan, or Directors Plan, became effective upon the execution of the underwriting agreement in connection
our initial public offering. As of December 31, 2010, an



F-22

##### Table of Contents

aggregate of 486,000 shares of common stock were reserved for future issuance under the Directors plan. This share amount will automatically increase on January 1 of each year through
2017 by an amount equal to the excess of: the number of shares subject to options granted during the preceding calendar year, over the number of shares, if any, added back to the share reserve during the preceding calendar year. Upon election
to our board of directors, each non-employee director will receive an initial grant of a non-qualified option to purchase 51,000 shares of our common stock, which will vest in forty-eight equal monthly installments. Further, non-employee
directors receive an automatic annual grant of a non-qualified option to purchase 13,000 shares of common stock, which will vest in twelve equal monthly installments. The exercise price of any options granted to a non-employee director under
the Directors Plan is equal to 100% of the fair market value of our common stock on the date of the grant. The Directors Plan provides that options granted under the plan will become fully vested and exercisable in the event of a
change of control. In January 2011, 166,000 shares of common stock, which was equal to the number of shares subject to grants made under the Directors Plan in 2010, less the shares added back from cancellations, were added to the
Directors Plan.

2007 Employee Stock Purchase Plan

Under the terms of our ESPP, all eligible employees may purchase shares of common stock at 85% of the lower of the fair market value on the first date of each twelve-month offering period or the purchase date.
Employees may authorize us to withhold up to 15% of their compensation during any offering period, subject to certain limitations, to purchase shares of our common stock under the ESPP. The ESPP authorized up to 3,596,000 shares of common stock for
purchase by our employees during the year ended December 31, 2010. The ESPP share reserve will automatically increase on January 1 of each year through 2017 by the lesser of 1.5% of the total number of shares of common stock
outstanding on December 31 of the preceding calendar year, 2,308,000 shares of common stock, or a lesser amount of shares of common stock to be determined by our board of directors prior to the first day of the calendar year. In January 2011,
1,276,000 shares of common stock, which was 1.5% of the outstanding shares of common stock as of December 31, 2010, were added to the ESPP.

RF Magic 2000 Incentive Stock Plan

In connection with our acquisition of RF Magic, we assumed RF Magics 2000 Incentive Stock Plan, or the RF Magic Plan, including all of the
outstanding stock options issued under the RF Magic Plan, except those held by employees of RF Magics French subsidiary. The stock options under the RF Magic Plan that we assumed became options to purchase an aggregate of 2,685,000 shares of
our common stock. The stock options held by employees of RF Magics French subsidiary that we did not assume remained as options to purchase RF Magics common stock. At the time of the acquisition an aggregate of 195,000 shares of RF
Magics common stock were issuable upon exercise of the unassumed RF Magic options. The unassumed RF Magic options are a subject to put and call option agreements between us, RF Magic and the holders of these options. Under these put and call
option agreements, each share of RF Magic common stock issued upon exercise of the unassumed RF Magic options will be exchanged for 0.9344 shares of our common stock, which is equal to the number of shares of our common stock issued in exchange for
each outstanding share of RF Magic in the acquisition. We reserved 182,000 shares of our common stock for future issuance under the put and call option agreements as of December 31, 2007. In 2010 and 2009, 18,000 shares and 103,000 shares of
our common stock, respectively, were issued in connection with the exercise of RF Magic options subject to put and call option agreements. As of December 31, 2010, options to purchase up to 11,000 shares were vested and outstanding under
the RF Magic Plan with weighted average exercise price of $0.95 per share.

Stock option grants under the 2001 Plan and RF Magic Plan
are subject to an early exercise provision. Those under the RF Magic Plan allow for early exercise upon approval by our board of

directors. Shares of common stock obtained upon early exercise of unvested options or by restricted stock purchase rights are subject to our repurchase at the applicable original issue price and
will vest according to the respective agreement. As of December 31, 2010, 2009 and 2008, 53,000, 302,000 and 893,000 shares, respectively, were subject to our repurchase rights.

The consideration received for the exercise of an unvested stock option is considered a deposit of the exercise price, and thus is a liability that
is recorded by us. The liability associated with this potential for repurchase, and the related shares, are only reclassified into equity as the option award vests. As a result, we have recorded liabilities as of December 31, 2010, 2009
and 2008 of $0.1 million, $0.3 million and $0.8 million, respectively, for the unvested shares issued upon early exercise of stock options.

Combined
Incentive Plan Activity

A summary of our stock option award activity and related information under our existing incentive plans for
the years ended December 31, 2010, 2009 and 2008 is set forth below. The following summary excludes options to purchase up to 11,000, 35,000 and 147,000 shares of our common stock subject to put and call option agreements for RF Magic
options outstanding as of December 31, 2010, 2009 and 2008, respectively.

Stock-Based
Compensation Expense

Stock-based compensation expense recognized in our statement of operations in 2010, 2009 and 2008 included
compensation expense for stock-based options and awards granted subsequent to December 31, 2005, based on the grant date fair value. For options and awards granted, expenses are amortized under the straight-line method. Stock-based compensation
expense recognized in the statement of operations has been reduced for estimated forfeitures of options that are subject to vesting. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual
forfeitures differ from those estimates.

We allocated stock-based compensation expense as follows (in thousands):

##### Table of Contents

We granted options and other stock awards to consultants in connection with their service agreements.
For the years ended December 31, 2010, 2009 and 2008, we recorded compensation expense related to these awards of $0.4 million, $0.1 million and $0.1 million, respectively. The fair value of the awards was estimated using a Black-Scholes
option-pricing model.

We reviewed and updated our forfeiture rate, expected term and volatility assumptions during the year ended
December 31, 2010. The risk-free interest rate is based on zero coupon U.S. Treasury instruments with maturities similar to those of the expected term of the award being valued. We use a combination of our historical experience, the
contractual term and the average option term of a comparable peer group to determine the expected life of our option grants. The peer group historical term is used due to the limited trading history of our common stock. The estimated volatility
incorporates historical volatility of similar entities whose share prices are publicly available. The expected dividend yield was based on our expectation of not paying dividends on common stock for the foreseeable future.

The fair value of stock options granted to employees, directors and consultants was estimated at the grant date using the following assumptions:

In May 2009, we completed
an offer to exchange, or the Offer to Exchange, certain employee stock options to purchase shares of our common stock that were outstanding under our 2007 Plan, 2001 Plan, and RF Magic Plan, on a three-for-two basis for replacement options granted
under the 2007 Plan at an exercise price of $1.99 per share, which was the closing price of our common stock on May 15, 2009, as reported by The NASDAQ Global Market. At the expiration of the Offer to Exchange, we accepted elections to exchange
options to purchase 1,600,000 shares of common stock and, as a result, we granted replacement options to purchase 1,000,000 shares of common stock. The replacement options have new vesting schedules with vesting dates that are determined by adding
an additional vesting period of 12 months, or a shorter duration upon a change of control, to each vesting date under the existing vesting schedule of the options being replaced. However, no replacement option will vest sooner than 12 months from
its date of grant, unless a change of control occurs. The incremental value attributed to the option awards exchanged resulted in approximately $60,000 of stock-based compensation, which will be recognized over the vesting period of the new option
awards.

As of December 31, 2010, we estimate there were $14.8 million in total unrecognized
compensation costs related to employee stock option agreements, which are expected to be recognized over a weighted-average period of 1.4 years. As of December 31, 2010, we estimate there were $0.8 million of unrecognized compensation
costs related to the shares expected to be purchased through the ESPP, which are expected to be recognized over a remaining weighted-average period of 0.5 years.

At December 31, 2010, based on the weight of available evidence, including profitability in recent periods
and the availability of expected future taxable income, we concluded that it is more likely than not that the benefits of Federal deferred income tax assets will be realized. Accordingly, we reduced the valuation allowances on our Federal gross
deferred income tax assets. We continue to maintain a valuation allowance to offset the California deferred tax assets as realization of such assets does not meet the more-likely-than-not threshold required under accounting guidance given the
present lower apportionment factors now pertaining to our income taxes in California.

The net change in the total valuation allowance
was a decrease of $35.9 million in 2010. For the years ended December 31, 2009 and 2008, the valuation allowance increased by $4.1 million and $14.3 million, respectively.

At December 31, 2010, we had total federal and state net operating loss, or NOL, carryforwards of approximately $41.1 million and $32.7
million, respectively. Approximately $8.3 million of the federal NOL relates to stock option deductions which, upon realization, will result in an increase to paid-in capital and a decrease in income taxes payable. If not utilized, the federal and
state net operating loss carryforwards will begin to expire in 2021 and 2013, respectively.

##### Table of Contents

As of December 31, 2010, we had federal and state research and development tax credit, or
R&D, carryforwards of approximately $12.5 million and $11.4 million, respectively. The federal R&D tax credit carryforwards will begin to expire in 2021 unless previously utilized. The California R&D tax credit will carryforward
indefinitely; however, we presently expect that only a minor portion of this credit will be utilized each year thereby requiring such a long future period of California profits that it does not meet the more-likely-than-not criteria. As of
December 31, 2010, we had a California Manufacturers Investment Tax Credit, or MIC, carryforward of $0.1 million, which will begin to expire in 2011 unless previously utilized.

Pursuant to Sections 382 and 383 of the Internal Revenue Code of 1986, as amended, or the Internal Revenue Code, utilization of net operating
losses and credit carryforwards may be subject to an annual limitation due to future ownership change limitations provided by the Internal Revenue Code and similar state provisions. The tax benefits related to future utilization of federal and
state net operating losses and tax credit carryforwards may be limited or lost if cumulative changes in ownership exceed 50% within any three-year period. While there may have been prior changes in ownership, it is anticipated that we will be
able to utilize substantially all of our federal and state net operating losses and tax credit carryforwards

We recognize excess tax
benefits associated with the exercise of stock options directly to stockholders equity only when realized. Accordingly, deferred tax assets are not recognized for NOLs resulting from excess tax benefits. At December 31, 2010, deferred tax
assets did not include $3.2 million of excess tax benefits from share-based compensation.

On January 1, 2007, we adopted guidance
that prescribes a recognition threshold and measurement process for recording in the financial statements uncertain positions taken or expected to be taken in a tax return. As of December 31, 2010, the Companys unrecognized tax benefits
totaled $6.7 million, of which $5.4 million would impact the effective tax rate if recognized.

The following table summarizes the
activity related to our unrecognized tax benefits (in thousands):



|                                                |  |   |        |

We do not expect unrecognized tax benefits to change significantly over the next 12 months.

We file income tax returns in the United States and in various state jurisdictions with varying statutes of limitations. We are no longer subject
to income tax examination by tax authorities for years prior to 2005, however, net operating loss and research credit carryforwards arising prior to that year are subject to adjustment. Our policy is to recognize interest expense and penalties
related to income tax matters as a component of income tax expense. There were no accrued interest and penalties associated with uncertain tax positions as of December 31, 2010.

We have a defined contribution 401(k) plan for employees who are at least 21 years of age. Under the terms of the plan, employees may make voluntary contributions as a percentage of compensation, but not in excess
of the maximum amounts allowed under the Internal Revenue Code. Our contributions to the plan are discretionary and we made no contributions during the years ended December 31, 2010, 2009 and 2008.

14. Quarterly Financial Data (Unaudited)

The following table presents certain quarterly financial data for the eight consecutive quarters ended December 31, 2010. The unaudited
quarterly information has been prepared on the same basis as the audited consolidated financial statements and, in the opinion of management, includes all adjustments, consisting only of normal recurring adjustments, necessary for the fair
presentation of this data. We believe that our quarterly revenue, particularly the mix of revenue components, and operating results are likely to vary in the future. The operating results for any quarter are not necessarily indicative of the
operating results for any future period or for any full year.
