ENTROPIC COMMUNICATIONS, INC.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

March 31, 2008

1. Organization and Summary of Significant Accounting Policies

Business

Entropic Communications, Inc. (the Company) was organized under the laws of the state of
Delaware on January 31, 2001. The Company is a fabless semiconductor company that designs, develops and markets systems solutions to enable connected home entertainment.

In October 2007, the Company completed a 1-for-3.25 reverse stock split. The accompanying financial statements and notes to the financial statements give
retroactive effect to the reverse stock split for all periods presented.

Basis of Presentation

The accompanying interim unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally
accepted in the United States (GAAP) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X promulgated by the Securities and Exchange Commission (SEC). They do not include
all of the information and footnotes required by GAAP for complete financial statements. These financial statements should be read in conjunction with the Companys audited consolidated financial statements and notes thereto as of and for the
year ended December 31, 2007 included in the Companys Annual Report on Form 10-K (Annual Report) filed on March 3, 2008 with the SEC.

The interim condensed consolidated financial statements included herein are unaudited; however, they contain all normal recurring accruals and adjustments that, in the opinion of management, are necessary to present
fairly the Companys consolidated financial position, results of operations and cash flows as of and for the periods indicated. The interim results are not necessarily indicative of the results to be expected for future quarters or the full
year.

The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and its 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 condensed consolidated financial statements and accompanying notes. Among the significant estimates affecting the condensed consolidated financial statements are those related to business combinations, revenue recognition, allowance for doubtful
accounts, inventory reserves, long-lived assets (including goodwill and intangible assets), warranty reserves, valuation of warrants, valuation of equity securities and stock-based compensation. On an on-going basis, management reviews its estimates
based upon currently available information. Actual results could differ materially from those estimates.

Revenue Recognition

The Companys revenues are generated principally by sales of its semiconductor products. During the three months ended March 31, 2008 and 2007,
product revenues represented 98% and 100%, respectively, of its total net revenues. The Company also generates service revenues from development contracts.

The majority of the Companys sales occur through the efforts of its direct sales force. The remainder of the Companys sales occurs through distributors. During the three months ended March 31, 2008
and 2007, more than 99% of the Companys sales occurred through the efforts of its direct sales force.

##### Table of Contents

In accordance with SEC Staff Accounting Bulletin (SAB) No. 101, Revenue Recognition
in Financial Statements, and SAB No. 104, Revenue Recognition, the Company recognizes 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, the Company does not recognize revenue until all customer acceptance requirements have been met, when applicable.

A portion of
the Companys sales are made through distributors under agreements allowing for pricing credits and/or rights of return. Product revenues on sales made through these distributors are not recognized until the distributors ship the product to
their customers. The Company records reductions to revenues for estimated product returns and pricing adjustments, such as competitive pricing programs, in the same period that the related revenue is recorded. To date, product returns and pricing
adjustments have not been significant.

The Company also has entered into an inventory hubbing arrangement with a key customer.
Pursuant to this arrangement, the Company delivers products to the designated third party warehouse based upon the customers projected needs, but does not recognize product revenue unless and until the customer removes the Companys
products from the third party warehouse to incorporate into its own products.

The Company derives revenues from development contracts that
involve new and unproven technologies. Revenues under these contracts are deferred until customer acceptance is obtained, and other contract-specific terms have been completed in accordance with the completed contract method of American Institute of
Certified Public Accountants Statement of Position 81-1, Accounting for Performance of Construction-Type and Certain Production-Type Contracts. Provisions for losses related to development contracts, if any, are recognized in the period in
which the loss first becomes probable and reasonably estimable. The costs associated with development contracts are included in cost of service revenue. The Company defers the cost of services provided under its development contracts.

The Company acquired a development agreement in connection with the acquisition of RF Magic, Inc. (RF Magic) that provides the Company with
royalties in exchange for an exclusive right to manufacture and sell certain products. The Company has determined that it is not able to reliably estimate the royalties earned in the period the sales occur. Thus, the Company records revenues based
on cash receipts. The royalty revenue recorded during the three months ended March 31, 2008 and 2007 were $966,000 and $0, respectively.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentration of credit
risk consist primarily of cash and cash equivalents, marketable securities, accounts receivable, leases payable and lines of credit and loans payable. The Companys policy is to place its cash and cash equivalents with high quality financial
institutions in order to limit its credit exposure. Credit is extended based on an evaluation of the customers financial condition and a cash deposit is generally not required. The Company estimates potential losses on trade receivables on an
ongoing basis.

The Company invests cash in deposits and money market funds with major financial institutions, U.S. government
obligations, debt securities of corporations with strong credit ratings and a variety of industries. It is the Companys policy to invest in instruments that have a final maturity of no longer than two years, with a portfolio weighted average
maturity of no longer than 12 months.

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 done on a part-by-part basis. Once established, these adjustments are considered permanent and are not reversed until the related inventory is sold or disposed.

Guarantees and Indemnifications

In the ordinary course of business, the Company has 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 interim unaudited financial statements.

Rebates

The Company accounts for rebates in accordance with Emerging Issues Task Force (EITF) Issue No. 01-9, Accounting for Consideration Given by a Vendor to a Customer (Including a Reseller of the
Vendors Products), and, accordingly, at the time of the sale accrues 100% of the potential rebate as a reduction to revenue and does not apply a breakage factor. The amount of these reductions is based upon the terms included in various
rebate agreements. The Company reverses the accrual for unclaimed rebates amounts as specific rebate programs contractually end or when management believes unclaimed rebates are no longer subject to payment and will not be paid.

Warranty Accrual

The Companys products
are subject to warranty periods of one year or more. The Company provides for the estimated future costs of replacement upon shipment of the product as cost of net revenues. The Company has not incurred significant warranty claims to date. The
warranty accrual is based on managements best estimate of expected costs associated with product failure and historical product failures.

Research and Development Costs

Research and development costs are expensed as incurred and primarily include costs
related to personnel, outside services (which consist primarily of contract labor services), fabrication masks, architecture licenses, engineering design development software and hardware tools, allocated overhead expenses and depreciation of
equipment used in research and development.

Income Taxes

The Company utilizes the liability method of accounting for income taxes as set forth in Statement of Financial Accounting Standards (SFAS) No. 109, Accounting for Income Taxes (SFAS
109). Under the liability method, deferred taxes are determined based on the temporary differences between the financial statement and tax basis of assets and liabilities using tax rates expected to be in effect during the years in which the
basis differences reverse. A valuation allowance is recorded when it is more likely than not that some of the deferred tax assets will not be realized.

The Company also follows Financial Accounting Standards Board (FASB) issued Interpretation No. 48, Accounting for Uncertainty in Income TaxesAn Interpretation of FASB Statement
No. 109 (FIN 48) which provides detailed guidance for the financial statement recognition, measurement and disclosure of uncertain tax positions recognized in an enterprises financial statements in accordance with SFAS
109. Income tax positions must meet a more-likely-than-not recognition threshold at the effective date to be recognized upon the adoption of FIN 48 and in subsequent periods. The Company recognizes potential accrued interest and penalties related to
unrecognized tax benefits within operations as income tax expense.

Stock-Based Compensation

Effective January 1, 2006, the Company adopted the provisions of SFAS No. 123 (revised 2004), Share-Based Payment (SFAS
123R), including the provisions of SAB No. 107 (SAB 107) and SAB No. 110 (SAB 110). Under SFAS 123R, stock-based compensation cost is measured at the grant date, based on the estimated fair value of the award,
and is recognized as expense over the employees requisite service period. The Company has not granted awards with vesting subject to market conditions. The Company adopted the provisions of SFAS 123R using the prospective transition method.
Accordingly, prior periods have not been revised for comparative purposes.

The valuation provisions of SFAS 123R apply to new awards and
to awards that are outstanding on the effective date, January 1, 2006, which are subsequently modified or canceled. Prior to the adoption of SFAS 123R, the Company used the intrinsic value method prescribed by Accounting Principles Board
Opinion No. 25, Accounting for Stock Issued to Employees (APB 25), related interpretations, and the disclosure-only provisions of SFAS No. 123, Accounting for Stock-Based Compensation for employee stock options
and recorded compensation cost for options granted at exercise prices that were less than market value of the Companys common stock at the date of grant. Pursuant to SFAS 123R, as the Company utilized the minimum value method through
December 31, 2005, the Company will continue to recognize compensation expense relating to unvested awards as of the date of adoption using APB 25 which is the same accounting principle originally applied to those awards.

##### Table of Contents

The stock-based compensation for the Companys 2007 Employee Stock Purchase Plan (ESPP)
was determined using the Black-Scholes option pricing model and the provisions of FASB Technical Bulletin No. 97-1, Accounting under Statement 123 for Certain Employee Stock Purchase Plans with a Look-Back Option, as amended by SFAS
123R.

The Company accounts for stock-based compensation awards granted to non-employees in accordance with EITF Issue No. 96-18,
Accounting for Equity Instruments That Are Issued to Other Than Employees for Acquiring, or in Conjunction with Selling, Goods or Services (EITF 96-18). Under EITF 96-18, the Company determines the fair value of the 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 either (1) the date at which a commitment for performance by the counterparty to earn the equity instruments is reached, or (2) the date at which the
counterpartys performance is complete.

Due to the adoption of SFAS 123R, the Company recognizes 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, the Company follows the with and without approach excluding any
indirect effects to be realized until after the utilization of all other tax benefits available to the Company.

Segment Reporting

SFAS No. 131, Disclosures about Segments of an Enterprise and Related Information(SFAS 131), establishes
standards for the way public business enterprises report information about operating segments in annual consolidated financial statements and requires that those enterprises report selected information about operating segments in interim financial
reports. SFAS 131 also establishes standards for related disclosures about products and services, geographic areas and major customers.

Operating segments are defined as components of an enterprise for which separate financial information is available and evaluated regularly by the chief operating decision maker, or decision-making group, in deciding how to allocate
resources and in assessing performance. The Company is organized as, and operates 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. The Companys chief operating decision maker is its Chief Executive Officer (CEO). The CEO
reviews financial information presented on a consolidated basis evaluating financial performance and allocating resources. There are no segment managers who are held accountable for operations below the consolidated financial statement level. The
Companys assets are primarily located in the United States of America and not allocated to any specific region. Therefore, geographic information is presented only for total revenue.

Recently Issued Accounting Standards

In
September 2006, FASB issued SFAS No. 157, Fair Value Measurements(SFAS 157), which defines fair value, establishes a framework for measuring fair value under GAAP and expands disclosures about fair value measurements. SFAS
157 does not require any new fair value measurements but rather eliminates inconsistencies in guidance found in various prior accounting pronouncements. The Company adopted this pronouncement as of January 1, 2008 for financial instruments.
Although the adoption of SFAS 157 did not have an impact on its interim financial results, the Company is now required to provide additional disclosures as part of its financial statements. See Note 2 for information and related disclosures
regarding the Companys fair value measurements.

In February 2007, the FASB issued SFAS No. 159, The Fair Value Option for
Financial Assets and Financial Liabilities, which permits entities to choose to measure eligible financial instruments and certain other items at fair value that are not currently required to be measured at fair value. Unrealized gains and
losses on items for which the fair value option have been elected are reported in earnings at each subsequent reporting date. The Company adopted this pronouncement in the first quarter of 2008 and it did not have an impact on its interim financial
results.

In June 2007, the FASB ratified EITF Issue No. 07-3, Accounting for Nonrefundable Advance Payments for Goods or Services
to Be Used in Future Research and Development Activities(EITF 07-3). EITF 07-3 requires non-refundable advance payments for goods and services to be used in future research and development activities to be recorded as an asset and
the payments to be expensed when the research and development activities are performed. The Company adopted this standard in the first quarter of 2008 and it did not have an impact on its interim financial results.

In December 2007, the FASB issued SFAS No. 141R, Business Combinations(SFAS 141R). SFAS 141R establishes principles and
requirements for how the acquirer of a business recognizes and measures in its financial statements the identifiable assets acquired, the liabilities assumed, and any noncontrolling interest in the acquiree. The statement also provides guidance for
recognizing and measuring the goodwill acquired in the business combination and determines what information to disclose to enable users of the financial statement to evaluate the nature and financial effects of the business combination. SFAS 141R is
effective for financial statements issued for fiscal years beginning after December 15, 2008. Accordingly, any business combinations the Company engages in will be recorded and disclosed following existing GAAP until January 1, 2009. The
Company expects SFAS 141R will have an impact on its consolidated financial statements when effective, but the nature and magnitude of the specific effects will depend upon the nature, terms and size of the acquisitions consummated after the
effective date. The Company is still assessing the impact of this standard on its future consolidated financial statements.

2. Supplemental Financial Information

Fair Value of Financial Instruments

The Company held 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 commercial paper and corporate bonds of high credit quality. Marketable securities were carried at amortized cost
which approximated fair value.

SFAS 157 establishes 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.

Deferred Rent

The Company recognized rent expense on a straight-line basis over the lease term as defined in SFAS No. 13, Accounting for Leases. In addition, the Company recorded landlord allowances for tenant
improvements as deferred rent, in accordance with FASB Technical Bulletin No. 88-1, Issues Related to Accounting for Leases. The deferred rent is amortized over the lease term as a reduction of rent expense. As of March 31, 2008 and
December 31, 2007, there was $2,556,000 and $1,301,000, respectively, of unamortized deferred rent recorded as a component of other long-term liabilities.

Purchase Commitments

The Company had firm purchase order commitments for the acquisition of inventory as of March 31, 2008 and December 31, 2007 of $14,338,000 and $11,910,000, respectively.

Stock-Based Compensation

The Company has in
effect equity incentive plans under which incentive stock options and non-qualified stock options have been granted to employees, directors and consultants to purchase shares of the Companys 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. These equity plans include the 2007 Equity Incentive Plan and the 2007 Non-Employee Directors Stock Option Plan under which the Company continues to
grant incentive stock options and non-qualified stock options. These plans are described in the Annual Report.

The Company also grants
stock awards under the ESPP. Under the terms of the ESPP, eligible employees may purchase shares of the Companys common stock at the lesser of 85% of the fair market value of the Companys common stock on the offering date or the purchase
date.

Stock-based compensation expense recognized in the Companys statement of operations for the three months ended March 31, 2008
and 2007 included compensation expense for stock-based options and awards granted subsequent to December 31, 2005, based on the grant date fair value estimated in accordance with SFAS 123R. For options and awards granted during the three months
ended March 31, 2008 and 2007, expenses are amortized under the straight-line method. Stock-based compensation expense recognized in the statement of operations for the three months ended March 31, 2008 and 2007 has been reduced for estimated
forfeitures of options that are subject to vesting. SFAS 123R requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates.

The fair value of options granted after January 1, 2006 and awards under the ESPP are estimated on the grant date using the Black-Scholes option
valuation model. This valuation model requires the Company to make assumptions and judgments about the variables used in the fair value calculation, including the expected life of the option or award, the volatility of the price of Companys
common stock, the expected risk-free interest rate and the expected dividend yield. The expected life for stock options reflects the application of the simplified method set out in SAB 107, as renewed by SAB 110. The expected life of an award
granted under the ESPP is based upon the length of the applicable offering periods. 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. The
simplified method defines the life as the average of the contractual term of the options and the weighted-average vesting period for all option tranches. The estimated volatility reflects the application of the interpretive guidance provided by SAB
107 and, accordingly, incorporates historical volatility of similar entities whose share prices are publicly available. The expected dividend yield is based on the Companys expectation of not paying dividends on the common stock for the
foreseeable future.

The following assumptions are used to value options and awards granted under the plans in connection with the
Companys equity incentive plans for the three months ended March 31, 2008 and 2007:

For the three months ended March 31, 2008 and 2007, the Company recorded stock-based
compensation expense for non-employees totaling $26,000 and $25,000, respectively. For the three months ended March 31, 2008 and 2007, the Company recorded stock-based compensation expense for the ESPP totaling $377,000 and $0, respectively.

In January 2008, the President and Chief Operating Officer of the Company resigned. In connection with his resignation, the Company
accelerated vesting of approximately 114,000 shares subject to stock options held by this former employee. The modification resulted in approximately $575,000 of additional stock compensation expense.

As of March 31, 2008 and December 31, 2007, the Company estimates there were $33,163,000 and $32,999,000 in total unrecognized compensation
costs related to unvested employee stock option agreements, which are expected to be recognized over a weighted-average period of 3.1 and 2.8 years, respectively. As of March 31, 2008, the Company estimates there were $714,000 of unrecognized
compensation costs related to the shares expected to be purchased through the ESPP, which are expected to be recognized over a weighted-average period of 0.8 years.

As of March 31, 2008, the Company had 8,195,000 authorized shares available for future
issuance under all of its equity incentive plans.

3. Income Taxes

The Company calculates its interim income tax provision in accordance with Accounting Principles Board Opinion No. 28,Interim Financial Reporting and FASB Interpretation No. 18,Accounting for
Income Taxes in Interim Periods. At the end of each interim period, the Company estimates the annual effective tax rate and applies that rate to its ordinary quarterly earnings. The tax expense or benefit related to significant, unusual or
extraordinary



14



---

##### Table of Contents

items that will be separately reported or reported net of their related tax effect and are individually computed, are recognized in the interim period in
which those items occur. In addition, the effect of changes in enacted tax laws or rates or tax status is recognized in the interim period in which the change occurs.

The computation of the annual estimated effective tax rate at each interim period requires certain estimates and significant judgment including, but not limited to, the expected operating income for the year,
projections of the proportion of income earned and taxed in foreign jurisdictions, permanent and temporary differences as a result differences between amounts measured and recognized in accordance with tax laws and financial accounting standards,
and the likelihood of recovering deferred tax assets. The accounting estimates used to compute the provision for income taxes may change as new events occur, additional information is obtained or as the tax environment changes. When the
Companys annual estimated income tax rate changes, the year-to-date effect of the change is recorded in the current period, which can cause fluctuations in effective tax rates in interim periods.

The effective tax rate for the three months ended March 31, 2008 was (4.15)% compared to 0% for the three months ended March 31, 2007. The
change in the effective tax rate is primarily due to the Companys expectations to be in a taxable income position for the year ended December 31, 2008. The Company will utilize a portion of its net operating loss carryforwards to offset
regular federal taxes and state taxes; however, the Company expects to incur a federal alternative minimum tax. This U.S. federal alternative minimum tax as well as a provision for foreign taxes is the cause for the change in the effective tax rate
for the period reported. There were no discrete items recorded in the three months ended March 31, 2008.

FIN 48 prescribes a
recognition threshold and measurement process for recording in the financial statements uncertain tax positions taken or expected to be taken in a tax return. Additionally, FIN 48 provides guidance on de-recognition, classification, accounting in
interim periods and disclosure requirements for uncertain tax positions.

On January 1, 2007, the Company adopted the provisions of
FIN 48. Included in the unrecognized tax benefits of $7,054,000 as of December 31, 2007 was $3,075,000 of tax benefits that, if recognized, would reduce the Companys annual effective tax rate. The remainder of the unrecognized tax
benefits in the amount of $3,979,000 will reduce goodwill. There have been no changes during the three months ended March 31, 2008 for any uncertain tax positions and the Company does not expect its unrecognized tax benefits to change
significantly over the next 12 months. There were no accrued interest and penalties associated with uncertain tax positions as of March 31, 2008 or December 31, 2007.

The Company files federal and state income tax returns in the United States and various other income tax returns in foreign jurisdictions. The Company is
not currently under audit or has not been notified of any impending examinations by any tax jurisdiction.

4. Net Income Per Share

Under the provisions of SFAS No. 128, Earnings per Share, basic loss per share is computed by dividing net loss attributable to common
stockholders by the weighted average number of shares of common stock outstanding for the period. Diluted loss per share is computed using the weighted average number of shares of common stock and dilutive common equivalent shares outstanding during
the year. Common equivalent shares from stock options and other common stock equivalents are excluded from the computation when their effect is antidilutive. The Company was in a loss position for all periods presented and, accordingly, there is no
difference between basic loss per share and diluted loss per share.

7. Subsequent Events

In April 2008, the Company entered into a Consent and Amendment to Loan and Security Agreement with Silicon Valley Bank to extend the term of its credit facility to April 2009 and increase the maximum amount of credit
from $7,000,000 to $10,000,000. The amount available under the credit line may be decreased by certain commitments, such as the $1,160,000 standby letter of credit that secures the Companys performance under its headquarters facilities lease.

In April 2008, the Company acquired certain specified assets of Vativ Technologies, Inc. (Vativ), including Vativs
intellectual property rights, existing product lines, inventory and equipment, for $5,900,000 in cash and approximately $1,000,000 in assumed liabilities. The Company contributed $850,000 of the purchase price to an escrow fund which is available to
satisfy potential indemnity claims.

|Item 2. | 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 our unaudited condensed
consolidated financial statements and the related notes thereto contained in Part I, Item 1 of this Quarterly Report on Form 10-Q, or Quarterly Report, and our consolidated financial statements and related notes as of and for the year ended
December 31, 2007 and the related Managements Discussion and Analysis of Financial Condition and Results of Operations contained in our Annual Report on Form 10-K for the year ended December 31, 2007, or Annual Report, filed with the
Securities and Exchange Commission, or SEC, on March 3, 2008.

Forward-Looking Statements

The following discussion contains forward-looking statements, which involve risks and uncertainties. These forward-looking statements include, but are
not limited to, statements concerning our strategy, future operations, competitors, future financial position, future revenues, projected costs, prospects and plans and objectives of management. These forward-looking statements 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, continue, ongoing and similar expressions, and variations or negatives of these words. Forward-looking statements are not guarantees of future performance and are
subject to risks, uncertainties and assumptions that are difficult to predict. Therefore, our actual results could differ materially and adversely from those expressed in any forward-looking statements as a result of various factors, some of which
are listed under Risk Factors in Part II, Item 1A and elsewhere of this Quarterly Report, and in our other filings with the SEC. We operate in a very competitive and rapidly changing environment. New risks emerge from time to time.
It is not possible for our management to predict all risks, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained
in any forward-looking statements in this Quarterly Report. Forward-looking statements herein speak only as of the date of this Quarterly Report. Unless required by law, we undertake no obligation to update or revise any forward-looking statements
to reflect new information or future events or developments. Thus, you should not assume that our silence over time means that actual events are bearing out as expressed or implied in such forward-looking statements.

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 other multimedia
content such as movies, music, games and photos are brought into and delivered throughout the home. Our products include home networking chipsets based on the Multimedia over Coax Alliance, or MoCA, standard, high-speed broadband access chipsets,
integrated circuits that simplify and enhance digital broadcast satellite services and silicon television tuner integrated circuits. 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.

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 Inc., or RF Magic, a provider of digital broadcast satellite outdoor unit and
silicon television tuner solutions. Since inception, we have invested heavily in product development and have not yet achieved profitability on a quarterly or annual basis. Our revenues have grown from $3.7 million in 2005 to $41.5 million in 2006
to $122.5 million in 2007, driven primarily by demand for our home networking products. Our revenues have increased from $20.0 million during the three months ended March 31, 2007 to $42.0 million during the three months ended March 31,
2008, driven primarily by demand for our home networking products and, to a lesser extent, from sales resulting from the RF Magic acquisition. As of March 31, 2008, we had an accumulated deficit of $96.2 million.

We generate revenues principally by sales of our semiconductor products. We also generate service
revenues from development contracts. We principally sell our products directly to either original design manufacturers, or ODMs, or original equipment manufacturers, or OEMs. 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 revenues. Sales to these customers are in turn driven by service providers that purchase our customers products which incorporate our products. Substantially all of our revenues are dependent upon
three major service providers, Verizon Communications, Inc. through its FiOS deployment, EchoStar Satellite, LLC and DIRECTV. In addition, we are dependent on sales outside of the United States for almost all of our revenues and expect that to
continue in the future.

In the three months ended March 31, 2008, Motorola, Inc., or Motorola, Actiontec Electronics, Inc., or
Actiontec, and Jabil Circuit (Wuxi) Co., Ltd., or Jabil Circuit, accounted for 36%, 26% and 13%, respectively, of our net revenues. In the three months ended March 31, 2007, Motorola, Actiontec and Jabil Circuit accounted for 47%, 35% and 16%,
respectively, of our net revenues. We expect to continue to have major concentrations of sales to a relatively small number of ODM and OEM customers.

In the three months ended March 31, 2008, 95% of our revenues were derived from Asia, 4% were derived from Europe, and 1% was derived from the United States and other North American countries. In the three months
ended March 31, 2007, 99% of our revenues were derived from Asia and 1% was derived from the United States and other North American countries. Many of our ODM and OEM customers in Asia incorporate our chipsets into products that they sell to
U.S.-based service providers.

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 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 fabrication mask costs. 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.

In February 2008, we relocated our two separate facilities in San Diego, California, into a 90,000 square foot facility which serves as our corporate headquarters.

In April 2008, we acquired certain specified assets of Vativ Technologies, Inc., or Vativ, including Vativs intellectual property rights, existing
product lines, inventory and equipment for $5.9 million in cash and approximately $1.0 million in assumed liabilities. We contributed $0.9 million of the purchase price to an escrow fund which is available to satisfy potential indemnity claims.

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 our initial public offering. 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 acquire complementary businesses or technologies.

Critical Accounting Policies and Estimates

Our discussion and analysis of our financial condition and the results of operations are based on our financial statements which have been prepared in
accordance with U.S. generally accepted accounting principles, or GAAP. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue and expenses. We base
our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are
not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. Our critical accounting policies are discussed in our Annual Report and there have been no material changes made to
these policies since the date of our Annual Report.

This $22.0 million increase in net revenues for the three months ended March 31, 2008
compared to the three months ended March 31, 2007 was driven primarily by demand for our home networking products and, to a lesser extent, from sales of digital broadcast satellite, or DBS, outdoor unit chips resulting from the RF Magic
acquisition.

The $13.7 million increase in gross profit for the three months ended March 31, 2008 compared
to the three months ended March 31, 2007 was due to higher revenues from the sales of our home networking chipsets and DBS outdoor unit chips. The increase in gross margin was primarily due to a decrease in the unit costs of our home networking
chipsets principally as a result of more favorable manufacturing costs, as well as the contribution in the three months ended March 31, 2008 from the sales of our DBS outdoor unit products. Additionally, as a result of the RF Magic acquisition
in 2007, which we accounted for by using the purchase method of accounting as required by SFAS No. 141, Business Combinations,cost of net revenues included $1.2 million of amortization of developed technology.

The $9.1 million increase in research and development expenses for the three months ended
March 31, 2008 compared to the three months ended March 31, 2007 was primarily due to increased personnel costs of $6.5 million (of which $1.7 million was due to stock-based compensation), overhead allocations of $1.1 million,
and development tool and supply costs of $0.9 million. The remainder of this increase resulted from a variety of expenditures principally related to customer-driven projects. In general, some of this $9.1 million increase was a result of the RF
Magic acquisition. Research and development headcount increased from 61 full-time employees as of March 31, 2007 to 195 full-time employees (170 employees in research and development and 25 employees in operations) as of March 31,
2008 (including employees added from the RF Magic acquisition in June 2007).

The $2.6 million increase in sales and marketing expenses included increased personnel costs
of $2.0 million (of which $0.6 million was due to stock-based compensation), overhead allocations of $0.3 million, and increased trade show and travel costs of $0.2 million primarily due to a general increase in business activities.
In general, some of this $2.6 million increase was a result of the RF Magic acquisition. Sales and marketing headcount increased from 21 full-time employees as of March 31, 2007 to 57 full-time employees as of March 31, 2008 (including
employees added from the RF Magic acquisition in June 2007).

The $2.8 million increase in general and administrative expenses during the three months ended
March 31, 2008 as compared to the corresponding period in 2007 included increased personnel costs of $1.7 million (of which $1.2 million was due to stock-based compensation), increased accounting expenses of $0.2 million due to being
a public reporting company, and legal fees of $0.4 million primarily due to a general increase in business activities. The remainder of this increase resulted from a variety of expenditures principally driven by our growth. In general, some of
this $2.8 million increase was a result of the RF Magic acquisition. General and administrative headcount increased from 11 full-time employees as of March 31, 2007 to 29 full-time employees as of March 31, 2008 (including employees added
from the RF Magic acquisition in June 2007).

During the three months ended March 31, 2008, we recorded a $1.1 million restructuring
charge related to the relocation of our headquarters into a 90,000 square foot facility in San Diego, California. The restructuring charge consisted of approximately $0.8 million of lease termination costs and approximately $0.3 million for the
impairment of property and equipment and other long-term assets.

Liquidity and Capital Resources

As of March 31, 2008, we had cash and cash equivalents of $16.5 million and marketable securities of $18.6 million.

We have entered into a Loan and Security Agreement with Silicon Valley Bank under which we have access to a credit line that is secured against substantially all of our tangible and intangible assets, excluding
intellectual property. Under the terms of our Loan and Security Agreement, as amended, we may borrow up to $10 million under our credit line. The amount available under our credit line may be decreased by certain commitments, such as the $1.2
million standby letter of credit that secures our performance under our headquarters facilities lease. The interest on amounts drawn down under the credit line is payable on a monthly basis 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. We have not borrowed any money from our credit line in 2008. As of April 3, 2008, $8.6 million was
available to us under our credit line and no amount was outstanding under our credit line.

Operating Activities. Our operating
activities used $7.7 million of cash in the three months ended March 31, 2008. Cash flow from operating activities for the three months ended March 31, 2008 resulted primarily from a net loss of $3.9 million and an increase in accounts
receivable of $13.4 million, which was primarily driven by higher sales, with a majority of the sales occurring later in the quarter. This was offset by stock-based compensation of $3.6 million, depreciation and amortization of $2.5 million, mostly
due to the RF Magic acquisition, a $1.2 million increase in other long-term liabilities, a $1.1 million decrease in inventory, primarily driven by sales timing, an increase in interest expense attributable to the write-off of debt discount
associated with our repayment of our credit facilities, and impairment of assets from restructuring charge attributable to the relocation of our facilities. The remaining changes in operating cash flows primarily reflect increases in accounts
payable and decreases in prepaid assets.

Net cash used in operating activities was $6.3 million in the three months ended March 31,
2007, primarily consisting of a net loss of $1.1 million, an increase of $3.5 million in accounts receivable, primarily driven by higher sales, and an increase of $6.9 million in inventory, primarily driven by higher expected sales. This was offset
by an increase in accounts payable of $4.6 million. The remaining changes in operating cash flows primarily reflect increases in depreciation and amortization, revaluation of preferred stock warrant liabilities and stock-based compensation.

Investing Activities. We used $20.0 million cash in investing activities in the three months ended March 31, 2008 compared to
$4.9 million in the three months ended March 31, 2007. Our increase in cash available for investing activities resulted primarily from the net proceeds received upon the sale of our common stock at our IPO. Our investing activities primarily
consisted of the purchase and maturities of marketable securities and purchases of property and equipment.

Capital expenditures were $3.9
million and $0.2 million for the three months ended March 31, 2008 and 2007, respectively. The capital expenditures incurred within the three months ended March 31, 2008 primarily consisted of tenant improvements and equipment for our
newly leased facilities in San Diego, California. The capital expenditures during the three months ended March 31, 2007 primarily consisted of computer and test equipment purchases. We anticipate that further capital expenditures will be
required to support future growth.

Financing Activities. Our financing activities used cash of $7.7 million in the three months ended
March 31, 2008, which was primarily driven by the payoff of debt outstanding under line of credit and loans in the amount of $8.9 million. This amount was offset by cash provided by the net proceeds from warrant exercises. Net cash provided by
financing activities was $0.4 million for the three months ended March 31, 2007, primarily consisting of stock option exercises, and was offset by principal payments of software licenses and capital lease obligations.

We expect to experience an increase in our operating expenses in absolute dollars, particularly in research and development expenses, but also in sales
and marketing, and general and administrative expenses, for the foreseeable future, in order to execute our business strategy and to support our growth. As a result, we anticipate that operating expenses, as well as planned capital expenditures,
will constitute a material use of our cash resources.

We believe that our cash, cash equivalents and marketable securities of $35.1
million, together with the $8.6 million available to us under our credit line as of March 31, 2008 and our expected cash flow from operations, 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
acquire complementary businesses or technologies. 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, 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.

Indemnities

In the ordinary course of business, we have entered into agreements with customers that include indemnity provisions. Based on
historical experience and information known as of March 31, 2008, we have not recorded any indemnity obligations.

In 2007, we were
contacted by Motorola on two occasions requesting that we indemnify Motorola against claims by third parties that products sold by Motorola that incorporate our products infringe one or more of the third parties patents. No specific amounts of
indemnity have been sought. We are currently in the process of evaluating Motorolas requests for indemnity and the underlying third party claims, and at the present time, due to the preliminary nature of the requests and the early status of
our investigations, we are unable to predict the ultimate outcome of these matters.

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.

Recent Accounting Pronouncements

In September 2006,
the Financial Accounting Standards Board, or FASB, issued Statement of Financial Accounting Standards, or SFAS, No. 157, Fair Value Measurements, or SFAS 157, which defines fair value, establishes a framework for measuring fair value
under GAAP and expands disclosures about fair value measurements. SFAS 157 does not require any new fair value measurements but rather eliminates inconsistencies in guidance found in various prior accounting pronouncements. We adopted this
pronouncement as of January 1, 2008 for financial instruments. Although the adoption of SFAS 157 did not have an impact on its interim financial results, we are now required to provide additional disclosures as part of our financial statements.

##### Table of Contents

In February 2007, the FASB issued SFAS No. 159, The Fair Value Option for Financial Assets and
Financial Liabilities, which permits entities to choose to measure eligible financial instruments and certain other items at fair value that are not currently required to be measured at fair value. Unrealized gains and losses on items for which
the fair value option has been elected are reported in earnings at each subsequent reporting date. We adopted this pronouncement in the first quarter of 2008 and it did not have an impact on our interim financial results.

In June 2007, the FASB ratified Emerging Issues Task Force Issue No. 07-3, Accounting for Nonrefundable Advance Payments for Goods or Services to
Be Used in Future Research and Development Activities, or EITF 07-3. EITF 07-3 requires non-refundable advance payments for goods and services to be used in future research and development activities to be recorded as an asset and the payments
to be expensed when the research and development activities are performed. We adopted this standard in the first quarter of 2008 and it did not have an impact on our interim financial results.

In December 2007, the FASB issued SFAS No. 141R, Business Combinations, or SFAS 141R. SFAS 141R establishes principles and requirements for
how the acquirer of a business recognizes and measures in its financial statements the identifiable assets acquired, the liabilities assumed, and any noncontrolling interest in the acquiree. The statement also provides guidance for recognizing and
measuring the goodwill acquired in the business combination and determines what information to disclose to enable users of the financial statement to evaluate the nature and financial effects of the business combination. SFAS 141R is effective for
financial statements issued for fiscal years beginning after December 15, 2008. Accordingly, any business combinations we engage in will be recorded and disclosed following GAAP until January 1, 2009. We expect SFAS 141R will have an
impact on our consolidated financial statements when effective, but the nature and magnitude of the specific effects will depend upon the nature, terms and size of the acquisitions consummated after the effective date. We are still assessing the
impact of this standard on our future consolidated financial statements.



|Item 3. | 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 non-U.S. customers for our products, 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 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, debt securities of corporations with strong credit ratings
and 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.

Our cash and cash equivalents are not subject to significant interest rate risk due to the short maturities of these instruments. As of March 31,
2008, the carrying value of our cash and cash equivalents approximated fair value.

Our marketable securities, consisting of
U.S. Treasury and agency obligations, commercial paper, corporate notes and bonds, time deposits, foreign notes and certificates of deposits, are generally classified as held-to-maturity and are stated at cost, adjusted for amortization of
premiums and discounts to maturity. In the past, certain of our short term marketable securities were classified as available-for-sale and were stated at fair value, which was equal to cost due to the short-term maturity of these securities. In the
event that there were to be a difference between fair value and cost in any of our available-for-sale securities, unrealized gains and losses on these investments would be reported as a separate component of accumulated other comprehensive income
(loss).

Our investment policy for marketable securities requires that all securities mature in two years or
less, with a weighted average maturity of no longer than 12 months. As of March 31, 2008, the carrying value of $18.6 million approximated the fair value of these securities. The fair value of our marketable securities fluctuates based on
changes in market conditions and interest rates; however, given the short-term maturities, we do not believe these instruments are subject to significant market or interest rate risk.

Investments in fixed rate interest earning instruments carry a degree of interest rate risk. Fixed rate securities may have their market value adversely
impacted due to rising interest rates. Due in part to these factors, our future investment income may fall short of expectations due to changes in interest rates.



|Item 4T. | 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
rules and forms of the SEC 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 Securities Exchange Act of 1934, as amended, or the
Exchange Act, prior to filing this Quarterly 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 Quarterly Report. Based on their evaluation, our chief executive officer and
chief financial officer concluded that our disclosure controls and procedures were effective as of the end of the period covered by this Quarterly Report.

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 our fiscal quarter ended March 31, 2008 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 our fiscal quarter ended March 31, 2008 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II: OTHER INFORMATION



|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 risks described below in addition to the other cautionary statements and risks described elsewhere, and
the other information contained in this Quarterly Report, Annual Report and in our other filings with the SEC. 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. If any of these known or unknown risks or uncertainties actually occurs, our business, financial condition, results of operations and/or liquidity could be seriously harmed. In that
event, the trading price of our common stock could decline, and you could lose some or all of your investment.

The risk factors set
forth below with an asterisk (*) next to the title are new risk factors or risk factors containing changes from the risk factors previously disclosed in our Annual Report.

Risks Related to Our Business

We have a history of losses and may not achieve or sustain profitability in the
future.*

We have never been profitable on an annual basis or in any fiscal quarter. We incurred net losses before accretion of
redeemable convertible preferred stock of $3.9 million for the three month period ended March 31, 2008 and $32.0 million, $7.1 million and $12.2 million for the years ended December 31, 2007, 2006 and 2005, respectively. As of
March 31, 2008, we had an accumulated deficit of $96.2 million. Accordingly, there can be no assurance if or when we may achieve profitability. Though our revenues increased from approximately $41.5 million for the year ended
December 31, 2006 to $122.5 million for the year ended December 31, 2007, a portion of that growth was attributable to businesses we acquired during the year, and we may not achieve similar growth in future periods. You should not
rely on our operating results for any prior quarterly or annual periods as an indication of our future operating performance. Moreover, we expect to make significant expenditures related to the development of our products and the expansion of our
business, including research and development, sales and marketing and general and administrative expenses. As a public company, we also incur significant legal, accounting and other expenses that we did not incur as a private company. Additionally,
we may encounter unforeseen difficulties, complications, product delays and other unknown factors that require additional expenditures and unforeseen difficulties or costs associated with the integration of acquired assets or businesses. As a result
of these expenditures, we may have to generate and sustain substantially increased revenue to achieve profitability. If we are unable to achieve adequate revenue growth, we may not achieve or sustain profitability and our stock price could decline.

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 us.

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. 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 expect
to face future competition in the sale of MoCA-compliant chipsets. Our current and potential competitors may also establish cooperative relationships among themselves or with third parties. If so, competitors or alliances that include our
competitors may emerge that could acquire significant market share. 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.

##### Table of Contents

Currently, we face competition from a number of established companies that offer products based on
competing technologies, such as DOCSIS, versions of xDSL, Ethernet, HomePNA, HomePlug AV, Wi-Fi, WiMedia, which is based on UWB technology, and WiMAX. 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 us. Given their capital resources, many of these larger organizations are in a better position to withstand any
significant reduction in capital spending by customers or market downturns in the markets in which we compete. 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. In addition, many of our competitors have been in operation much longer than us 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 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 effectively address any of these factors, alone or in combination with others, could seriously harm our
business, operating results and financial condition.

In addition, consolidation by industry participants or acquisitions of our
competitors by our customers or suppliers could result in competitors with 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 could emerge rapidly and acquire significant market share. In addition, some of our suppliers and customers offer or may 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, during the three months ended March 31, 2008 and the year ended December 31, 2007, ten customers accounted for approximately 94% and 96%,
respectively, of our revenues. During the three months ended March 31, 2008, Motorola, Actiontec and Jabil Circuit accounted for 36%, 26% and 13%, respectively, of our revenues. Our inability to generate anticipated revenues from our key
existing or targeted customers, or a significant shortfall in sales to 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. To date, only one major service provider, Verizon, has publicly announced its intention to use the MoCA standard for home networking in its FiOS deployment. We also primarily rely on two major service providers,
EchoStar and DIRECTV, to deploy products using our DBS outdoor unit solutions. During the three months ended March 31, 2008 and the year ended December 31, 2007, products sold to our customers that were incorporated into products purchased
by Verizon, EchoStar and DIRECTV accounted for substantially all of our revenues. 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. Our operating results in the foreseeable future will continue to depend on a limited number of service providers demand for products which
incorporate our products.

##### Table of Contents

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 will lose market share and our operating
results will be adversely affected.

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 Verizons ability to compete in the market for
the delivery of HD video and other multimedia content. Therefore, factors influencing Verizons ability to compete in this market, such as laws and regulations regarding local cable franchising, could have an adverse effect on our current
ability to sell home networking products. In addition, our DBS 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 multiple 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
television tuners are competing with a variety of internet protocol-based video delivery solutions, including xDSL technology and certain fiber optic-based solutions. Many of these technologies compete effectively with satellite set-top boxes and do
not require television 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
their 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 such multimedia content delivery solutions based on the
MoCA standard is relatively new, still evolving, and difficult to predict. In the near-term, 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, Wi-Fi and WiMedia. In the future, we expect other semiconductor manufacturers to compete with us in the manufacture and sale of MoCA-compliant chipsets. It is therefore uncertain whether the MoCA standard will achieve and
sustain high levels of demand and market acceptance. Moreover, deployment of services or electronic devices utilizing MoCA-based solutions may be delayed or slower than we anticipate. 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 success will depend to a substantial extent on the willingness of service providers, ODMs and OEMs to adopt the MoCA standard for multimedia content
delivery. As of March 31, 2008, only one major service provider, Verizon, had publicly announced its intention to use the MoCA standard for home networking. 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. It is critical to our success that additional service providers, including telecommunications carriers and cable operators, adopt the MoCA standard for home networking.

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. 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 geographic 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 and 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 foreign markets are unsuccessful, the demand for these products may not develop as anticipated or decline, either of which could
adversely affect our future revenues. Moreover, these foreign 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.

##### Table of Contents

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, xDSL, 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.

The success of our DBS 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
home networking products, we also derive a significant portion of our revenues from sales of our DBS 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 DBS 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 DBS outdoor unit products. If the demand for our DBS 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 television tuners and HDMI products.*

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 television tuners and High Definition Multimedia Interface, or HDMI, receivers and HDMI switches. For example, sellers of module tuners that offer similar or better functionality than our silicon television
tuner solutions may dramatically lower their prices and become more competitive than us in the tuner market. In addition, our silicon television tuners may not 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 television tuners and HDMI 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 television tuners is highly dependent on our relationships with demodulator manufacturers.*

Our silicon television tuners are designed to be interoperable with various specific demodulator integrated circuit products that are designed and
manufactured by other companies. Historically, RF Magic 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. Our current principal demodulator relationship is with STMicroelectronics in the digital
video broadcasting terrestrial and cable, Advanced Television



32

##### Table of Contents

Systems Committee, or ATSC, and digital broadcast satellite markets. In the digital broadcast satellite market, our tuners are currently marketed with an
STMicroelectronics demodulator; however, STMicroelectronics has recently released its own radio frequency silicon tuner that will replace some of the tuners we sell, and STMicroelectronics may continue to release other competing tuners or require us
to reduce our prices on the tuners we sell with their demodulators.

If any of the current or prospective demodulator manufacturers with
whom we have or intend to have relationships 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 television tuners would be substantially reduced.

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 have experienced significant growth in a short period of time, including growth related to our acquisitions of RF Magic and Arabella in 2007, and
certain specified assets of Vativ in April 2008. For example, we have increased our headcount from 83 full-time employees as of December 31, 2006 to 281 full-time employees as of March 31, 2008 (including employees which we added as
part of our acquisitions of RF Magic and Arabella). We also hired an additional 17 full-time employees in connection with the consummation of the Vativ acquisition. We anticipate that further expansion of our infrastructure and headcount will be
required to achieve planned expansion of our product offerings, projected increases in our customer base and anticipated growth in the number of our product deployments. For example, in the first quarter of 2008, we moved into a larger facility for
our operations in San Diego, California to accommodate our growth. Our rapid growth has placed, and will continue to place, a significant strain on our administrative and operational infrastructure. Our success in managing our operations and growth
will be dependent upon our ability to:



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



| |  |  | expand our facilities and equipment;
| | - |  | ------------------------------------



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



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

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

Further, we intend 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.

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 completed in 2007 and 2008. These challenges include the following:



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



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



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

##### Table of Contents

| |  |  | 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 successfully integrate 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.

In addition, we have recorded significant amounts of goodwill and other intangible assets in connection with the acquisitions we completed
in 2007 and will record additional amounts of goodwill and other intangible assets in connection with our acquisition of certain specified assets of Vativ in April 2008. The carrying amount of these long-lived assets could be reduced through
impairment charges in future periods if events or changes in circumstances, including adverse industry conditions or a downturn in demand for our products, indicate that such amount is not recoverable. Any such impairment charge could have a
material adverse impact on our results of operations.

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.

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

We
intend to continue to actively pursue acquisitions, strategic relationships, joint ventures or 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 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; and
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | requirements to record substantial charges and amortization expense related to certain purchased 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 management 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.

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.

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, while we are currently the only manufacturer of MoCA-compliant chipsets, we expect that other chipset manufacturers who are members of MoCA will produce competing chipsets and create pricing pressure for such products. 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.

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 for the three months ended March 31, 2008 was $13.3 million and was $35.2 million, $11.6 million and $9.6 million for the years ended December 31, 2007, 2006 and 2005,
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. We occasionally have 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. 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 successfully develop future products would have a material adverse effect on our business, financial condition and results of operations.

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:

| | - |  | -------------------------------------------------------------------------------------------



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

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.

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. Furthermore, 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.

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.

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 these existing 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 compatibility with products, software or equipment found in our customers
existing 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 interoperability arrangements with equipment and software vendors for the use or integration of their technology with our products. These arrangements would give us access to and
enable interoperability with various products in the connected home entertainment market. If these relationships fail, we would have to devote substantially more resources to the development of alternative products and the support of our products,
and our efforts may not be as effective as the combined solutions with our current customers. 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 service providers 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, our sales have been seasonal in nature. 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 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. Even after an order is
received, our customers may cancel these orders or request a decrease in production quantities. Any such cancellation or decrease 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 must sell at reduced prices, or that any resulting disputes with our customers may
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.

In the fourth quarter of 2007, we entered into 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. Prior to the
implementation of this hubbing arrangement with Motorola, we recognized revenues on sales of our products to Motorola upon shipment of those products to Motorola or its ODM partners. Under the hubbing arrangement, 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 may 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.

The semiconductor and communications industries have historically experienced cyclical behavior and prolonged downturns, which could impact our operating results, financial condition and cash flows.

The semiconductor industry has historically exhibited cyclical behavior, which at various times has included significant downturns in
customer demand. Though we have not yet experienced any of these industry downturns,

we may in the future. Because a significant portion of our expenses is fixed in the near term or is incurred in advance of anticipated sales, we may not be
able to decrease our expenses rapidly enough to offset any unanticipated shortfall in revenues. If this situation were to occur, it could adversely affect our operating results, cash flow and financial condition. Furthermore, the semiconductor
industry has periodically experienced periods of increased demand and production constraints. If this happens in the future, we may not be able to produce sufficient quantities of our products to meet the increased demand. We may also have
difficulty in obtaining sufficient manufacturing, assembly and test resources from our manufacturers. Any factor adversely affecting the semiconductor industry in general, or the particular segments of the industry that our products target, may
adversely affect our ability to generate revenue and could negatively impact our operating results.

Additionally, the communications
industry has experienced pronounced downturns, and these cycles may continue in the future. To respond to a downturn, many service providers, OEMs and ODMs may slow their research and development activities, cancel or delay new product development,
reduce their inventories and take a cautious approach to acquiring products, which would have a significant negative impact on our business. If this situation were to occur, it could adversely affect our operating results, cash flow and financial
condition. In the future, any of these trends may also cause our operating results to fluctuate significantly from period to period, which may increase the volatility of the price of our stock.

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 Taiwan Semiconductor Manufacturing Company, Jazz Technologies, Inc., United Microelectronics Corp., Amkor Technologies, Inc. and Giga Solution Tech. Co., Ltd.
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.
| | - |  | -------------------------------------

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 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 and qualify new third party manufacturers, if available.

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 a significant 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.



39

##### Table of Contents

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. 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 third party sales representatives to assist in selling our products, and the failure of these representatives to perform as expected could reduce our future sales.

We sell our products to some of our customers through third party sales representatives. Our relationships with some of these third party sales
representatives are relatively new and we are unable to predict the extent to which our third party sales representatives will be successful in marketing and selling our products. Moreover, many of our third party sales representatives also market
and sell competing products. Our third party sales representatives 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 that will be able to 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 recruit additional or replacement third party sales representatives, 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 or perception 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



40



---

##### Table of Contents

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 service providers to dispatch service vehicles to customer premises, often referred to as 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 managements time and other resources.

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. There is intense competition for qualified personnel in the markets in which we compete. Moreover, the cost of living in the San Diego area,
where our corporate headquarters are located, has been an impediment to attracting new employees in the past, and we expect that this will continue to impair our ability to attract and retain employees in the future. The 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. We do not currently have any key person life insurance covering any executive officer or employee, nor do we
have employment agreements with most of our employees.

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. 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, or FCC, 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 could have an adverse effect on Verizons and other 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 FCC or any other federal or state communications regulatory agency, much of the equipment into which these products are incorporated is subject to 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 FCC specifications.

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 in connection with our expansion in order 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. 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.

Adverse U.S. and international economic conditions may adversely affect our revenues, margins and
profitability.*

Adverse economic conditions may result in decreased spending by our customers for our products. In addition, our
products, and the services and devices that contain or use our products, are discretionary purchases for consumers. Consumers are generally more willing to make discretionary purchases during periods of favorable economic conditions. As a result of
unfavorable economic conditions, including higher interest rates, increased taxation, higher unemployment, lower consumer confidence in the economy, higher consumer debt levels and lower availability of consumer credit, consumers purchases of
discretionary items may decline, which could adversely affect our revenues. Moreover, we may 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,
increases in general and administrative expenses and other factors. These conditions may harm our margins and 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.

Maintaining and improving our financial controls and the requirements of being a public company may strain our resources, divert managements attention and
affect our ability to attract and retain qualified board members and management. *

We completed our initial public offering in
December 2007. As a public company, we are subject to the reporting requirements of the Exchange Act, the Sarbanes-Oxley Act of 2002, or the Sarbanes-Oxley Act, and the Nasdaq Stock Market Rules, or Nasdaq rules. The requirements of these rules and
regulations will increase our legal and financial compliance costs, make some activities more difficult, time-consuming or costly and may also place significant strain on our personnel, systems and resources. The Exchange Act requires, among other
things, that we file annual, quarterly and current reports with respect to our business, operating results and financial condition.

The
Sarbanes-Oxley Act requires, among other things, that we maintain effective disclosure controls and procedures and internal control over financial reporting. Ensuring that we have adequate internal financial and accounting controls and procedures in
place is a costly and time-consuming effort that needs to be re-evaluated frequently. We are in the process of documenting, reviewing and, where appropriate, improving our internal controls and procedures in preparation for compliance with the SEC
regulations adopted pursuant to Section 404 of the Sarbanes-Oxley Act, which requires annual management assessments of the effectiveness of our internal control over financial reporting and a report by our independent auditors. Both we and our
independent auditors will be

weaknesses, significant deficiencies or other areas for further attention or improvement. Implementing any appropriate changes to our internal controls may require specific compliance training for our directors, executive officers and employees,
entail substantial costs to modify our existing accounting systems, and take a significant period of time to complete. Such changes may not, however, be effective in maintaining the adequacy of our internal controls, and any failure to maintain that
adequacy, or any consequent inability to produce accurate financial statements on a timely basis, could increase our operating costs and could materially impair our ability to operate our business. Moreover, effective internal controls are necessary
for us to produce reliable financial reports and are important to help prevent fraud. As a result, our failure to satisfy the requirements of Section 404 on a timely basis could result in the loss of investor confidence in the reliability of
our financial statements, which in turn could cause the market value of our common stock to decline.

In accordance with Nasdaq rules, we
are required to maintain a majority independent Board of Directors. We also expect that the various rules and regulations applicable to public companies will make it more difficult and more expensive for us to maintain directors and
officers liability insurance, and we may be required to accept reduced coverage or incur substantially higher costs to maintain coverage. If we are unable to maintain adequate directors and officers insurance, our ability to
recruit and retain qualified directors, especially those directors who may be deemed independent for purposes of Nasdaq rules, and executive officers will be significantly curtailed and we may be required to indemnify directors and officers out of
our own cash resources, rather than rely on insurance policies, which could materially adversely affect our liquidity and results of operations.

Our
effective tax rate may increase or fluctuate, and we may not derive the anticipated tax benefits from the planned 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. We are in the process of expanding 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. As a result of this anticipated change and an expanding international customer base, we expect that an increasing percentage of
our consolidated pre-tax income will be derived from, and reinvested in, our international operations. Moreover, we anticipate that this pre-tax income will be subject to foreign tax at relatively lower tax rates when compared to the
U.S. federal statutory tax rate and as a consequence, our future effective income tax rate is expected to 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, or that our international operations and sales will result in a lower effective income tax rate. In addition, our future effective income tax rate could be adversely affected if tax authorities challenge
our international tax structure 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, 2007, we had federal and
state net operating loss carryforwards of $62.9 million and $50.5 million, respectively, and federal and state research and development tax credit carryforwards of $7.5 million and $6.3 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 become profitable. However, to the extent our use of net operating loss
and tax

credit carryforwards is further limited by the issuance of common stock in our initial public offering or in 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 use our net operating loss and tax credit carryforwards without
such further limitation.

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 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 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 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 products or technology. Monitoring unauthorized use of our technology is difficult and we cannot be certain that the steps we have taken to
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 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 technology, our ability to
compete effectively could be harmed.

Our participation in patent pools and standard 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. If we had a disagreement with a MoCA member regarding which of our patent claims are necessary to implement MoCA specifications, this could result in a lawsuit. Any such lawsuit, regardless
of its merits, could be time-consuming,



44



---

##### Table of Contents

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. This 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 relatively 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 actively seek new patents in our field. It is difficult or impossible to fully keep 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 we, our customers or the service providers that purchase products from our customers may in the future 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 would result in our trade secrets being disclosed to the public and the potential loss of
intellectual property rights in our software, 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. Revenues
outside of the United States comprised 99% of our total revenues for the three months ended March 31, 2008 and 98% for the year ended December 31, 2007. 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 United States 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 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 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.

##### Table of Contents

Fluctuations in exchange rates between and among the currencies in which we do business may adversely affect our
operating results.*

We transact business internationally, currently mainly focusing on Israel, Taiwan, Japan, Korea, China and
Europe. As a result, we may experience foreign exchange gains or losses due to the volatility of other currencies compared to the U.S. dollar. Our sales have been historically denominated in U.S. dollars and an increase in the U.S. dollar relative
to the currencies of the countries in which our customers operate could materially affect the demand of our non-U.S. customers for our products, thereby forcing these customers to reduce their orders, which would adversely affect our business. We
incur a portion of our expenses in currencies other than the U.S. dollar, including New Israeli Shekels. Our operating results are denominated in U.S. dollars and the difference in exchange rates in one period compared to another may directly
impact period to period comparisons of our operating results. Furthermore, currency exchange rates have been especially volatile in the recent past and these currency fluctuations may make it difficult for us to predict our results.

Currently, we have not implemented any strategies to mitigate risks related to the impact of fluctuations in currency exchange rates. Even if we were to
implement hedging strategies, not every exposure can be hedged, and, where hedges are put in place based on expected foreign exchange exposure, they are based on forecasts which may vary or which may later prove to have been inaccurate. Failure to
hedge successfully or anticipate currency risks properly could adversely affect our operating results. We cannot predict future currency exchange rate changes.

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.

Our third party contractors are concentrated primarily in areas subject to earthquakes and other natural disasters. 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 these areas is significant due to the proximity of major earthquake fault lines to the facilities of our foundry, assembly and test subcontractors. For
example, in December 2006, major earthquakes occurred in Taiwan. The occurrence of additional earthquakes or other natural disasters could result in the disruption of our foundry or assembly and test capacity. Any disruption resulting from such
events 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

An active trading market for our common stock may not be sustained.

Prior to our initial public offering in December 2007, there was no public market for our common stock. We cannot predict the extent to which investor interest in our company will sustain an active trading market on
the Nasdaq Global Market or any other stock market or how liquid any such market might become. An active public



47

##### Table of Contents

market for our common stock may not be sustained. If an active public market is not sustained, it may be difficult for an investor to sell his, her or its
shares of our common stock at a price that is attractive to such investor, or at all.

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;
| | - |  | ----------------------------------------------------------



| |  |  | 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 our sales;
| | - |  | ---------------------------------



| |  |  | 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;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



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



| |  |  | 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;
| | - |  | -----------------------------------------------------



| |  |  | our inclusion or deletion from certain stock indices;
| | - |  | -----------------------------------------------------



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



| |  |  | announcements of changes in our senior management;
| | - |  | --------------------------------------------------



| |  |  | 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, 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.

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.*

Sales of a substantial number of shares of our common stock or the issuance of securities convertible into or exercisable for
shares of our common stock could occur at any time. These sales or issuances, or the perception in the market that the holders of a large number of shares intend to sell shares, could reduce the market price of our common stock. As of March 31,
2008, we had 68,651,867 outstanding shares of common stock. This includes the shares that we sold in our IPO, all of which may be resold in the public market without restriction. All of the remaining shares may be sold upon the expiration of lock-up
agreements 180 days after the date of our initial public offering unless the shares are held by an affiliate of ours. In addition, as of March 31, 2008, we had granted outstanding options to purchase 7,839,615 shares of our common stock that,
if exercised, would result in these additional shares becoming available for sale upon expiration of the lock-up agreements.

##### Table of Contents

Moreover, holders of up to approximately 43,973,899 shares of common stock have rights, subject to some
conditions, to require us to file registration statements covering their shares or to include their shares in registration statements that we may file for ourselves or other stockholders. These rights will terminate two years following the
completion of our initial public offering, or for any particular holder with registration rights who holds less than one percent of our outstanding capital stock, at any time when all securities held by that stockholder that are subject to
registration rights may be sold pursuant to Rule 144 under the Securities Act of 1933, as amended, or the Securities Act, within a single 90 day period. If a large number of our shares of our common stock or securities convertible into our
common stock are sold in the public market after they become eligible for sale, the sales could reduce the trading price of our common stock and impede our ability to raise future capital.

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.

Our principal stockholders, executive officers and directors have substantial control over the company, which may prevent you and other stockholders from
influencing significant corporate decisions and may harm the market price of our common stock.*

As of March 31, 2008, our
executive officers, directors and holders of 5% or more of our outstanding common stock, beneficially owned, in the aggregate, approximately 28% of our outstanding common stock. These stockholders may have interests that conflict with yours and, if
acting together, have the ability to substantially influence or determine the outcome of matters submitted to our stockholders for approval, including the election and removal of directors and any merger, consolidation or sale of all or
substantially all of our assets. In addition, these stockholders, acting together, may have the ability to control our management and affairs. Accordingly, this concentration of ownership may harm the market price of our common stock by:



| |  |  | delaying, deferring or preventing a change in control;
| | - |  | ------------------------------------------------------



| |  |  | impeding a merger, consolidation, takeover or other business combination involving us; or
| | - |  | -----------------------------------------------------------------------------------------

If securities or industry analysts publish inaccurate or unfavorable research about our business, our stock price and trading volume could decline.

The trading market for our common stock will depend in part on the research and reports that securities or industry analysts
publish about us or our business. If one or more of the analysts who covers us downgrades our stock or publishes inaccurate or unfavorable research about our business, our stock price would likely decline. If one or more of these analysts ceases
coverage of us or fails to publish reports on us regularly, demand for our stock could decrease, which could cause our stock price and trading volume to decline.

We do not expect to pay any cash dividends for the foreseeable future.

The continued expansion of our business will
require substantial funding. Accordingly, we do not anticipate that we will pay any cash dividends on shares of our common stock for the foreseeable future. Any determination to pay dividends in the future will be at the discretion of our Board of
Directors and will depend upon our results of operations, financial condition, contractual restrictions, restrictions imposed by applicable law and other factors our Board of Directors deems relevant. Investors seeking cash dividends in the
foreseeable future should not purchase or hold our common stock.



|Item 2. | Unregistered Sales of Equity Securities and Use of Proceeds.
|------- | ------------------------------------------------------------



|(b) | Use of Proceeds
|--- | ---------------

The initial public offering of
our common stock was effected through a Registration Statement on Form S-1 (File No. 333-144899) that was declared effective by the SEC on December 6, 2007, which registered an aggregate of 9,200,000 shares of our common stock,
including 1,200,000 shares of common stock owned by selling stockholders that the underwriters had the option to purchase to cover over-allotments. Credit Suisse Securities (USA) LLC and Lehman Brothers Inc. were the joint book-running managers for
the IPO, with Thomas Weisel Partners LLC, JMP Securities LLC and ThinkEquity Partners LLC serving as co-managers. On December 12, 2007, 8,000,000 shares of common stock were sold on our behalf at a price of $6.00 per share, for an aggregate
gross offering price of $48 million. On January 8, 2008, the underwriters exercised their over-allotment option in full and purchased 1,200,000 shares of our common stock sold on behalf of the selling stockholders, at a price of $6.00 per
share, for an aggregate gross offering price of $7.2 million. Our IPO resulted in gross offering proceeds to us of $48 million and net offering proceeds to us, after deducting underwriting discounts, commissions and issuance costs, of approximately
$40.6 million.

As of March 31, 2008, we had invested $18.6 million of net proceeds from our initial public offering in short- and
intermediate-term, interest bearing obligations, investment-grade instruments, certificates of deposit and direct or guaranteed obligations of the U.S. government. Through March 31, 2008, we have used $12.9 million of the net proceeds to fund
the incremental working capital requirements to grow our business and consolidate our two San Diego facilities into our current corporate headquarters, and $9.1 million to repay our outstanding debt, including accrued interest. In April 2008, we
used approximately $5.9 million of the net proceeds to purchase certain specified assets of Vativ, $850,000 of which was contributed to and remains subject to an escrow fund which will be available to satisfy potential indemnity claims. The proceeds
used to date were used to make direct payments to third parties who were not our officers or directors (or their associates), persons owning ten percent or more of any class of our equity securities, or any other affiliate (except that the proceeds
used for salary expense included regular compensation expenses for officers). Redpoint Ventures and its affiliated venture funds own approximately 22% of Vativs outstanding capital stock. One of the members of our Board of Directors, John
Walecka, is a general partner of Redpoint Ventures. Mr. Walecka did not participate in the negotiations or deliberations concerning this acquisition. In addition, our chief technology officer, Itzhak Gurantz, owns less than 0.1% of Vativs
outstanding capital stock. Dr. Gurantz also did not participate in the negotiations or deliberations concerning this acquisition. The purchase price for the acquired assets was arrived at based on arms length negotiations with
Vativs management. The acquisition was unanimously approved by our Board of Directors, with Mr. Walecka abstaining from such vote.

There has been no material change in the planned use of proceeds as described in our final prospectus
filed pursuant to Rule 424(b)(4) of the Securities Act with the SEC on December 7, 2007. As described in our final prospectus, we anticipate using the remaining proceeds for working capital and general corporate purposes and may use a portion
of the net proceeds to acquire or license products, technologies or businesses, but we currently have no agreements or commitments relating to material acquisitions or licenses. We cannot specify with certainty all of the particular uses for the net
proceeds from our initial public offering. Accordingly, our management will have broad discretion in the application of the net proceeds.

Under the terms of our loan and security agreement with Silicon Valley Bank, we are not permitted to pay cash dividends without the banks prior consent. Accordingly, we do not anticipate that we will pay any cash dividends on shares
of our common stock for the foreseeable future. Any determination to pay dividends in the future will be at the discretion of our Board of Directors and will depend upon our results of operations, financial condition, contractual restrictions,
restrictions imposed by applicable law and other factors our Board of Directors deems relevant.

|Item 5. | Other Information
|------- | -----------------

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 is effective through May 2010. No employees were terminated in connection with the
restructuring plan. We accounted for the restructuring plan in accordance with SFAS No. 146, Accounting for Costs Associated with Exit or Disposal Activities. We recorded $1.1 million as a restructuring charge, including $0.8
million related to lease termination costs and $0.3 million related to the impairment of property and equipment and other long-term assets. Approximately $0.8 million of this charge will be settled in cash and is recorded as a restructuring
liability in our accounts payable and other accrued expenses as of March 31, 2008.
