NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

NOTE 1. ORGANIZATION AND BASIS OF PRESENTATION

Description of
BusinessExar Corporation and its subsidiaries (Exar or we) are a fabless semiconductor company that designs, develops, markets and sells power management and connectivity silicon solutions. Applying both analog and
digital technologies, our products are deployed in a wide array of applications such as portable electronic devices, set top boxes, digital video recorders, telecommunication systems and industrial automation equipment.

On August 25, 2007, Sipex Corporation (Sipex) became a wholly owned subsidiary of Exar and each share of Sipex common stock issued and outstanding
immediately prior to the effective time of the merger was converted into 0.6679 shares of our common stock. Approximately 16.5 million shares of our common stock were issued to former Sipex stockholders in connection with the merger.

Sipex designed, manufactured and marketed high performance, analog integrated circuits (ICs) used by original equipment manufacturers,
(OEMs), in the computing, consumer electronics, communications and networking infrastructure markets. The merger was accounted for as a purchase business combination. Accordingly, the results of operations of Sipex and estimated fair
value of assets acquired and liabilities assumed were included in our consolidated financial statements beginning August 26, 2007.

In December 2007,
we changed our fiscal year end from a fiscal year ending as of the last day of March to a 52-53 week fiscal year ending on the Sunday closest to March 31. As part of this change, each fiscal quarter will also end on the Sunday closest to the
end of the corresponding calendar quarter. The third quarter of fiscal year 2008 included 91 days from October 1, 2007 to December 30, 2007. The third quarter of fiscal year 2007 included 92 days from October 1, 2006 to
December 31, 2006.

Basis of Presentation and Use of Management Estimates The accompanying unaudited condensed consolidated financial
statements have been prepared in accordance with generally accepted accounting principles in the United States and include Exar and its wholly-owned subsidiaries. This financial information reflects all adjustments, which are, in our opinion, of a
normal and recurring nature and necessary to state fairly the statements of financial position, results of operations and cash flows for the dates and periods presented. The March 31, 2007 condensed consolidated balance sheet was derived from
the audited financial statements at that date. All significant inter-company transactions and balances have been eliminated. Certain balance sheet reclassifications have been made to prior period balances in order to conform to the current
periods presentation.

The financial statements include managements estimates and assumptions that affect the reported amounts of assets and
liabilities as of the date of the financial statements and the reported amounts of sales and expenses during the reporting periods. Actual results could differ from those estimates, and material effects on operating results and financial position
may result.

Prior to our merger with Sipex in August 2007, the functional currency of each of our foreign subsidiaries was the local currency of that
country. During the three months ended December 30, 2007, in connection with integrating and realigning our combined operations, we reassessed the economic facts and circumstances of each of our foreign subsidiaries. As a result, during the
three months ended December 30, 2007, the functional currencies for our foreign subsidiaries were changed to the U.S. Dollar. Accumulated other comprehensive loss reported in the condensed consolidated balance sheet before December 1, 2007
included approximately $20,000 related to the cumulative foreign currency translation adjustment of our subsidiaries prior to changing our functional currency.

The accounts of foreign subsidiaries have been remeasured into U.S. Dollars in accordance with the Financial Accounting Standards Board (FASB) Statement of Financial Accounting Standards No. 52, Foreign Currency
Translation(SFAS No. 52). Accordingly, foreign currency is remeasured to U.S. Dollars for financial purposes by using the U.S. Dollar as the functional currency and exchange gains and losses are reported in income
and expenses. These currency gains or losses are reported in interest income and other, net in the condensed consolidated statements of operations. Monetary balance sheet accounts are remeasured using the current exchange rate in effect at the
balance sheet date, for assets and liabilities, and for non-monetary items, the accounts are remeasured at the historical exchange rate. Revenues and expenses are remeasured at the average exchange rates for the period.

Revenue Recognition

We recognize revenue in accordance with the Securities and Exchange Commission (SEC) Staff Accounting Bulletin 104, Revenue Recognition (SAB 104). SAB 104 requires that four basic criteria must be met before
revenue can be recognized: (1) persuasive evidence of an arrangement exists; (2) delivery has occurred or services rendered; (3) the price is fixed or determinable; and (4) collectibility is reasonably assured.

We derive revenue from the sale of our products principally to distributors and to OEMs or their contract manufactures. Our delivery terms are primarily FOB shipping
point, at which time title and all risks of ownership are transferred to the customer. For the three and nine months ended December 30, 2007, approximately 25% and 31%, respectively, of our net sales were derived from product sales to our two
primary distributors, Future Electronics Inc. (Future) and Nu Horizon Electronics Corp. (Nu Horizons). Approximately 75% and 69%, respectively, of our net sales were derived from product sales to other distributors, OEM
customers and other non-distributors.

Non-distributors:

For non-distributors, revenue is recognized when title to the product is transferred to the customer, which occurs upon shipment or delivery, depending upon the terms of the customer order, provided that persuasive evidence of a sales
arrangement exists, the price is fixed or determinable, title has transferred, collection of the resulting receivables is reasonably assured, there are no customer acceptance requirements and there are no remaining significant obligations.
Provisions for returns and allowances for non-distributor customers are provided at the time product sales are recognized. An allowance for sales returns and allowances for customers is recorded based on historical experience or specific
identification of an event necessitating an allowance.

Distributors:

Our two primary distributors agreements permit the return of 3% to 5% of their purchases during the preceding quarter for purposes of stock rotation. For one of these distributors, a scrap allowance of 2% of the
proceeding quarters purchases is permitted. We also provide discounts to certain distributors based on volume of product ordered for a specific product with a specific volume range for a given customer over a period not to exceed one year.



| |  |  | Sell-in Basis: Revenue is recognized upon shipment if we conclude we can reasonably estimate the credits for returns, pricing allowances and/or other
concessions. We record an estimated allowance, at the time of shipment, based upon historical patterns of returns, and pricing allowances and other concessions (i.e., sell-in basis).
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Sell-through Basis: Revenue and the related costs of sales is deferred until the resale to the end customer if we grant more than limited rights of
returns, pricing allowance and/or other concessions or if we cannot reasonably estimate the level of returns and credits issuable (i.e., sell-through basis). Under the sell-through basis, accounts receivable are recognized and inventory
is relieved upon shipment to the distributor as title to the inventory is transferred upon shipment, at which point we have a legally enforceable right to collection under normal terms. The associated sales and cost of sales are deferred by
recording deferred income (gross profit margin on these sales) as shown on the face of the condensed consolidated balance sheet. When the related product is sold by our distributors to their end customers, at which time the ultimate
price we receive is known, we recognize previously deferred income as sales and cost of sales.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Our historical patterns of returns,
pricing allowances and other concessions with distributors have been fairly consistent, which has enabled us to reasonably estimate such allowances at the time of shipment. Therefore, we have historically recognized revenue on sales to all
distributors on a sell-in basis and recorded an estimated allowance, at the time of shipment, based on authorized and historical patterns of returns and other concessions. Concurrent with the merger with Sipex, we reassessed our expected ability to
continue to reasonably estimate such allowances for each of our distributors as well as for Sipexs distributors. Prior to the merger, Sipex recognized revenue on sales to all distributors on a sell-through basis. Consistent with Sipexs
past practice, we have concluded that we are not able to reasonably estimate such allowances at the time of shipment of products to Sipexs distributors. Therefore, we have determined that consistent with Sipexs past practice, we will
continue to recognize sales to Sipexs distributors on sell-through basis. In addition, as a result of the merger, our relationships, marketing and sales practices with our two primary distributors have changed. Further, as disclosed in Note 3
of the Notes to our condensed consolidated financials statements, Future is now a related party to Exar. As a result of these changes, we have concluded that we can no longer reasonably estimate returns, pricing allowances and other concessions at
the time of shipment of products to these distributors. Accordingly, as of August 26, 2007, we determined it was appropriate that revenue on all sales to Future and Nu Horizons be recognized on a sell-through basis.

##### Table of Contents

As a result of revenue on sales to our two primary distributors now being recognized on a sell-through basis, $6.5
million of revenue and $1.5 million of related cost of sales is deferred at December 30, 2007, and is included within Deferred income and Deferred income, related party on the condensed consolidated balance sheets.

NOTE 2. BUSINESS COMBINATION

Merger with Sipex Corporation
(Sipex)

On August 25, 2007, we completed our merger with Sipex, a company that designs, manufactures and markets high performance,
analog ICs used by OEMs in the computing, consumer electronics, communications and networking infrastructure markets. As a result of the merger, we have combined product offerings, increased technical expertise, distribution channels, customer base
and geographic reach as well as reduced expenses due to significant cost synergies.

On August 25, 2007, each share of Sipexs common stock
outstanding at the effective time of the merger was converted into 0.6679 shares of our common stock. As a result, approximately 16.5 million shares of our common stock were issued to former Sipex stockholders. The fair value of the common
stock issued was determined using a share price of $13.97, which represented the average closing price of our common stock for two trading days before and two trading days after May 8, 2007, the date the merger was announced. We assumed stock
options to purchase a total of approximately 2.2 million shares of our common stock. The fair value of options assumed was estimated by using the Black-Scholes option pricing model and a share price of $13.97. In addition, in connection with
the merger, we assumed warrants to purchase a total of approximately 280,000 shares of our common stock. The warrants are exercisable at any time for shares of our common stock at an initial exercise price of $9.63 per share, subject to adjustment
upon certain events. The warrants expire on May 18, 2011. The fair value of $5.31 for each warrant assumed was estimated by using the Black-Scholes option pricing model and a share price of $13.97.

The merger was accounted for as a purchase in accordance with FASB Statement of Financial Accounting Standards No. 141, Business Combination(SFAS
No. 141). Accordingly, the results of operations of Sipex and estimated fair value of assets acquired and liabilities assumed are included in our condensed consolidated financial statements from August 26, 2007.

The total estimated purchase price of the merger was as follows (in thousands):



|                                           |  |         |        
|------------------------------------------ |  | ------- | -------
|                                           |  | Amounts
|Fair value of Exar common stock issued     |  | $       | 229,999
|Fair value of options and warrants assumed |  |         | 16,701 
|Direct transaction costs                   |  |         | 4,038  
|                                           |  |         |        
|Total estimated purchase price             |  | $       | 250,738
|                                           |  |         |        

Purchase Price Allocation:

The allocation of the purchase price to Sipexs tangible and identifiable intangible assets acquired and liabilities assumed was based on their estimated fair values. Further adjustments may be included in the
allocation of the purchase price of Sipex as we complete our final analysis of the assets acquired and liabilities assumed, if such adjustments are determined within the purchase price allocation period (up to twelve months from the closing date).
The excess of the purchase price over the tangible and identifiable intangible assets acquired and liabilities assumed has been allocated to goodwill. Goodwill resulted primarily from our expectations of synergies from integration of Sipexs
product offerings with our product offerings. Goodwill is not expected to be deductible for tax purposes.

The estimated purchase price at August 25,
2007 has been preliminary allocated and adjusted in the three months ended December 30, 2007 as follows (in thousands):

We recorded an adjustment of $454,000 during the three months ended December 30, 2007 in connection with the
Billerica lease termination. Note 4 of Notes to our condensed consolidated financial statements contains information related to the cost of restructuring programs for Sipex employees and facilities. The costs were included as part of other
liabilities assumed as of August 25, 2007.

The following table sets forth the components of the identifiable intangible assets, which are being
amortized over their estimated useful lives on a straight-line basis (dollars in thousands):

Acquired In-Process Research and Development:

We recorded a charge of $8.8 million in acquired in-process research and development (IPR&D), associated with our merger with Sipex in the three months ended September 30, 2007. We allocated
the purchase price related to IPR&D through established valuation techniques with the assistance of a third-party service provider. IPR&D was expensed upon acquisition because technological feasibility had not been established and no future
alternative uses existed. The fair value of technology under development is determined using the income approach, which discounts expected future cash flows to present value, taking into account the stage of completion, estimated costs to complete,
utilization of patents and core technology, the risks related to successful completion, and the markets served. The cash flows derived from the IPR&D were discounted at discount rates ranging from 25% to 40%. The percentage of completion for
these projects ranged from 20% to 87% at the merger date.

The IPR&D projects underway at Sipex at the merger date were in the interface and power
management product families. Within interface, specific projects relate to new products in its Multiprotocol and RS485 families. Within power management, development activities relate to the commercialization of its digital power technology, LED
drivers, DC-DC regulators and controllers. All of these projects require further development and testing to bring them up to production. IPR&D projects for interface are expected to require $0.8 million to complete with expected revenue
generation beginning in mid calendar year 2008. IPR&D projects for power management are expected to require $2.2 million to complete. Product shipments of the IPR&D for the power management began in late calendar year 2007.

Pro Forma Financial Information:

The following unaudited pro forma financial information is based on the respective historical financial statements of Exar and Sipex. The unaudited pro forma financial information reflect the consolidated results of

NOTE 3. RELATED PARTY TRANSACTIONS

Alonim Investments Inc., our largest stockholder, and an affiliate of Future, owns approximately 7.6 million shares or approximately 16% of our outstanding common stock as of December 30, 2007. Sales to
Future are made under an agreement that provides protection against price reduction for its inventory of our products. We recognize revenue on sales to Future under the distribution agreement when Future sells the products to end customers. Future
has historically accounted for a significant portion of our net sales. It is our largest distributor worldwide and accounted for 18% and 19% of our total net sales for the three months ended December 30, 2007 and December 31, 2006,
respectively, and accounted for 19% and 20% of our total net sales for the nine months ended December 30, 2007 and December 31, 2006, respectively.

We reimbursed Future for approximately $27,000 and $45,000 of expenses for marketing promotional materials for the three and nine months ended December 30, 2007, respectively. We reimbursed approximately $2,000 of such expenses for
both the three and nine months ended December 31, 2006.

Upon our merger with Sipex, we appointed an executive vice president and chief financial
officer of Future to our board of directors. The board of directors has determined that this director is not independent within the meaning of The Marketplace Rule 4200(a)(15) of The NASDAQ Stock Market by virtue of our relationship with Future.

NOTE 4. RESTRUCTURING

On August 25, 2007, our
management approved and initiated plans to restructure the operations of Sipex to eliminate certain duplicative activities, reduce cost structure and better align product and operating expenses with existing general economic conditions. The Sipex
restructuring costs were accounted for as liabilities assumed as part of the purchase business combination as of August 25, 2007 in accordance with the Emerging Issues Task Force Issue No. 95-3, Recognition of Liabilities in Connection
with a Purchase Business Combination (EITF 95-3).

The following table sets forth restructuring liabilities which are included in other
accrued expenses on the balance sheet, and the activities affecting the liabilities during the three and nine months ended December 30, 2007 (in thousands):

During the three months ended December 30, 2007, we recorded an additional liability of $454,000 in connection with the Billerica lease termination.

For the three and nine months ended December 30, 2007, we paid cash severance of approximately $229,000 and $248,000, respectively, to the employees. The remaining balance of approximately $789,000 for severance
costs is expected to be paid out in the next nine months.

For the three and nine months ended December 30, 2007, we utilized approximately $391,000
and $502,000, respectively, of our restructuring accrual, primarily related to moving expenses at our Hillview facility and the lease expenses for the unused portion of the Billerica facility in Massachusetts. The remaining balance of approximately
$1.2 million is expected to be paid during the remaining terms of the lease contracts which extend through 2012.

NOTE 7. LONG-TERM INVESTMENTS

Our long-term investments balance at December 30, 2007 and March 31, 2007 are as follows (in thousands):



|                      |  |                  |       |               |   |

|Long-term investments |  | $                | 2,653 |               | $ | 2,670

We account for our long-term investments in TechFarm Ventures L.P. (Q), L.P. (TechFarm Fund) and
Skypoint Telecom Fund II (US), L.P. (Skypoint Fund) consisting of their respective portfolios of non-marketable equity securities under the cost method. In accordance with the EITF 03-1, The Meaning of Other-Than-Temporary Impairment and
its Application to Certain Investments, we periodically review and determine whether the investments are other-than-temporarily impaired, in which case the investments are written down to their impaired value.

In the three months ended December 31, 2006, we became aware that two of Skypoint Funds portfolio companies would be liquidated. We believed a portion of the
carrying value of our investment in the Skypoint Fund was other-than-temporarily impaired. We recorded an impairment charge against our earnings of $0.9 million in September 2006. In the three months ended September 30, 2007, we performed a
review of our investments and determined that two of the portfolio companies in the Skypoint Fund had limited cash on hand and financing opportunities were minimal. We concluded that a portion of the carrying value had been other-than-temporarily
impaired and recorded an impairment charge against our earnings of $0.4 million in September 2007.

In the nine months ended December 31, 2006, we
determined that the TechFarm Fund management fees continued to deplete the fund capital without any appreciation in the valuation of portfolio companies, and therefore concluded that a portion of the carrying value of our investment in the TechFarm
Fund was other-than-temporarily impaired. In September 2006, we recorded an impairment charge against our earnings of $0.1 million in connection with the TechFarm Fund. No impairment charge was recorded for either of the three months periods ended
December 30, 2007 and December 31, 2006.

During the three months ended December 30, 2007 and December 31, 2006, we made capital
contributions of approximately $148,000 and $160,000, respectively, to the Skypoint Fund. As of December 30, 2007, we have a remaining obligation to make a capital contribution of approximately $0.9 million to the Skypoint Fund upon its
request. We have no remaining capital contribution obligation to the TechFarm Fund at December 30, 2007.

NOTE 8. GOODWILL AND INTANGIBLE ASSETS

Goodwill

We account for goodwill in accordance
with FASB Statement of Financial Accounting Standards No. 142, Goodwill and Intangible Assets (SFAS No. 142). In accordance with SFAS No. 142, goodwill is not amortized, but instead is tested for impairment at least
annually and more frequently if certain indicators are present. We conduct our annual analysis of our goodwill and intangible assets in the fourth quarter of our fiscal year. The increase in the carrying amount of our goodwill from $5.2 million at
March 31, 2007 to $176.8 million at December 30, 2007 is due to our merger with Sipex on August 25, 2007.

The changes in the carrying
amount of goodwill for the nine month ended December 30, 2007 are as follow (in thousands):

NOTE 9. EARNINGS (LOSS) PER SHARE

Basic earnings per share (EPS) excludes dilution and is computed by dividing net income by the weighted average number of common shares outstanding for the periods in accordance with FASB Statement of
Financial Accounting Standards No. 128, Earnings Per Share (SFAS No. 128). Diluted EPS reflects the potential dilution that would occur if outstanding stock options or warrants to issue common stock, the unvested

For the three and nine months ended December 30, 2007, as we incurred a net loss, the weighted average number
of common shares outstanding equals the weighted average number of common and common equivalent shares assuming dilution. Approximately 393,000 and 492,000 shares of options and RSUs for the three and nine months ended December 30, 2007,
respectively, were excluded from our loss per share calculation. If we had income for these two periods, our diluted shares would have increased by these aforementioned amounts.

For the three and nine months ended December 30, 2007, approximately 5.4 million and 4.9 million options to purchase shares of common stock, at exercise prices ranging from $8.78 to $86.10 and $9.53 to
$86.10, respectively, were outstanding but were not included in the computation of diluted earnings per share because they were anti-dilutive under the treasury stock method. Approximately 280,000 warrants outstanding were also excluded from the
computation of diluted earnings per share because they were anti-dilutive under the treasury stock method for the three and nine months ended December 30, 2007.

For the three and nine months ended December 31, 2006, approximately 5.2 million and 5.1 million options to purchase common stock, at exercise prices ranging from $12.09 to $54.75 for both periods,
respectively, were outstanding but were not included in the computation of diluted earnings per share because they were anti-dilutive under the treasury stock method.

NOTE 10. COMMON STOCK REPURCHASES

On August 31, 2007, we established a new share repurchase plan (2007
SRP) and authorized the repurchase of up to $100 million of our common stock over the next twelve months. The 2007 SRP was in addition to a share repurchase plan announced in March 2001 (2001 SRP), which covered the repurchase of
up to $40 million of our common stock. The shares repurchased under the 2001 SRP fully utilized the $40 million authorization at December 30, 2007. As of December 30, 2007, the remaining authorized amount for stock repurchase under the
2007 SRP was $60.3 million with no termination date.

During the three and nine months ended December 30, 2007, we repurchased a total of
2.3 million and 4.7 million shares, respectively, of our common stock at an aggregate costs of $25.6 million and $58.0 million, respectively, under the 2007 SRP and 2001 SRP.

NOTE 11. STOCK-BASED COMPENSATION

Employee Stock Participation Plan (ESPP)

We have an Employee Stock Purchase Plan which permits employees to purchase common stock through payroll deductions at a purchase price that is
equal to 95% of our common stock price on the last trading day of each three-calendar-month offering period. Our ESPP is non-compensatory under FASB Statement of Financial Accounting Standards No. 123 (revised 2004), Share-Based Payment
(SFAS No. 123R).

##### Table of Contents

For the nine months ended December 30, 2007 and December 31, 2006, we issued 16,462 and 28,615 shares, at
weighted average prices of $12.66 and $12.53, respectively, to participating employees. For the three months ended December 30, 2007, we did not issue ESPP shares due to our change in fiscal quarter end. For the three months ended
December 31, 2006, we issued 10,408 shares at weighted average prices of $12.40. At December 30, 2007, approximately 1,680,000 shares of common stock were reserved for future issuance under our ESPP.

Stock Option Plans

On September 7, 2006, our
shareholders ratified the Exar Corporation 2006 Equity Incentive Plan (the 2006 Plan). The 2006 Plan authorizes stock options, stock appreciation rights, restricted stock, stock bonuses and other forms of awards granted or denominated in
common stock or units of common stock, as well as cash bonus awards. Individuals eligible to receive awards under the 2006 Plan include our officers, employees, our directors, and certain consultants and advisors. The 2006 Plan allows for
performance-based vesting and partial vesting based upon level of performance. At December 30, 2007, there were approximately 4,267,000 shares available for future grant.

Upon the merger with Sipex, we assumed options to purchase 2,215,421 shares of Sipex common stock (after the application of the exchange ratio in the merger) that had been granted by Sipex and Sipexs five option
plans: the 1997 Stock Option Plan, 1999 Stock Option Plan, 2000 Non-Qualified Stock Option Plan, 2002 Non-Statutory Stock Option Plan and 2006 Equity Incentive Plan. We can grant options or issue shares pursuant to the assumed Sipex plans, but only
to former Sipex employees or employees of the combined company hired after the merger. The 1997 Stock Option Plan expired in 2007. At December 30, 2007, there were approximately 618,000 shares available for future grant under the Sipex plans.

As of December 30, 2007, there were approximately 6,096,000 options outstanding under all stock option plans.

Generally, options under the 2006 Plan are granted with an exercise price of 100% of the fair value of the underlying stock on the date of grant and have a term of seven
years, although the 2006 Plan provides that options may be granted with a term of up to ten years. Options generally vest at a rate of 25%, on their anniversary date, over four years. The assumed Sipex plans generally allow for options which vest
ratably over five years from the date of grant for options granted before May 2002 and four years for options granted after April 2002. These options expire ten years from the date of grant.

Valuation Assumptions

We compute the fair value of stock options
utilizing the Black-Scholes option pricing model. Calculating stock-based compensation expense requires the input of highly subjective assumptions, including the expected term of the share-based awards, stock price volatility, and forfeiture
rates. We estimate the expected life of options granted based on historical exercise and post-vest cancellation patterns, which we believe are representative of future behavior. Our expected volatility is based on historical data of the market
closing price for our common stock as reported by The NASDAQ Global Market under the symbol EXAR and the expected term of our stock options. The risk-free interest rate assumption is based upon observed interest rates appropriate for the
expected term of our employee stock options. We do not currently pay dividends and have no plans to do so in the future. We estimate the forfeiture rates based on our historical voluntary and involuntary terminations prior to vesting.

The assumptions used in calculating the fair value of stock-based compensation represent our estimates, but these estimates involve inherent uncertainties and the
application of management judgment. As a result, if factors change and we use different assumptions, our stock-based compensation expense could be materially different in the future.

The assumptions used to estimate the fair value of stock options granted for the three and nine months ended December 30, 2007 and December 31, 2006 (annualized percentages) are shown below:

|(1) | Aggregate intrinsic value for stock options represents the difference between the exercise price and the closing price per share of our stock on December 30, 2007, multiplied
by the number of stock options outstanding, exercisable, or vested and expected to vest as of December 30, 2007.
|--- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The aggregate
intrinsic value in the table above represents the total pre-tax intrinsic value, based on the fair value of our common stock of $7.99 as of December 30, 2007, which would have been received by option holders if all option holders exercised
their options as of that date. The total number of in-the-money options vested and exercisable was 0.8 million for both periods ended December 30, 2007 and December 31, 2006.

Total intrinsic value of options exercised was approximately $0.7 million and $1.2 million for the three and nine months ended December 30, 2007, respectively.
Total intrinsic value of options exercised was approximately $0.1 million and $1.7 million for the three and nine months ended December 31, 2006, respectively.

Total cash received related to option exercises was $0.9 million and $3.2 million for the three and nine months ended December 30, 2007, respectively. The cash received related to option exercises was $0.4
million and $14.7 million for the three and nine months ended December 31, 2006, respectively. Upon option exercise, we issue shares of common stock.

We recorded a tax benefit of $0.02 million and $0.2 million related to the option exercises for the three and nine months ended December 30, 2007, respectively. We recorded a tax benefit of $0.2 million and $0.8 million related to
option exercise for the three months and nine months ended December 31, 2006, respectively.

Total unrecognized stock-based compensation cost of $6.4
million and $5.6 million at December 30, 2007 and December 31, 2006, respectively, will be recognized over a weighted average period of 2.70 and 1.63 years, respectively.

Stock-Based Compensation Expenses

Effective April 1, 2006, we adopted SFAS No. 123R by using the modified
prospective transition method. The modified

##### Table of Contents

prospective transition method requires that stock-based compensation expense be recorded for all new and unvested stock options that are expected to vest
over the requisite service periods beginning on April 1, 2006. Under SFAS No. 123R, we have elected to use the straight-line attribution method for expensing stock-based compensation. As stock-based compensation expense recognized in the
condensed consolidated statement of operations for the three and nine months ended December 30, 2007 and December 31, 2006 is based on awards ultimately expected to vest, it is reduced for estimated forfeitures.

We recorded stock-based compensation expense for the three and nine months ended December 30, 2007 and December 31, 2006 as follows (in thousands):

We modified approximately 202,000 stock options held by our former chief executive officer upon his departure in
December 2007. The modification provides an extended exercise period from three months as defined by the plan to six months. As a result of the modification, we recorded additional stock-based compensation expenses of approximately $9,000 during the
three months ended December 30, 2007.

Restricted Stock Awards and Units

In the second quarter of fiscal year 2007, we began issuing restricted stock units to employees and non-employee directors. Restricted stock units currently granted by us generally vest on the first or third
anniversary date from the grant date. Restricted stock units granted under the 2006 Plan are counted against authorized shares available for future issuance on the basis of two shares for every restricted stock unit issued. Prior to vesting,
restricted stock units do not have dividend equivalent rights, do not have voting rights and the shares underlying the restricted stock units are not considered issued and outstanding. Shares are issued on the date the restricted stock units vest.

Restricted Stock Awards (RSAs)

We awarded 30,000
shares of restricted stock to our former president and chief executive officer on March 24, 2005 in connection with his employment agreement. The restricted stock vests annually over a period of three years and has a grant date fair value of
$13.52. At December 31, 2006, 20,000 shares remained unvested with a remaining contractual life of 1.25 years. At December 30, 2007, there were no unvested shares of RSAs.

For the three and nine months ended December 31, 2006, we recorded stock-based compensation expense of $34,000 and $102,000, respectively, associated with these awards. Total unrecognized stock-based compensation
cost in connection with this restricted stock was $0.2 million at December 31, 2006. For the three and nine months ended December 30, 2007, no stock-based compensation expense was recorded and there was no unrecognized compensation cost at
December 30, 2007 associated with these awards.

During the nine months ended December 30, 2007, we granted the chairman of our board of
directors 10,000 shares of fully vested common stock and recorded approximately $134,000 as stock-based compensation expense.

Restricted Stock Units
(RSUs)

At December 30, 2007, there were 304,628 RSUs outstanding. The unrecognized stock-based compensation cost was $2.7 million at
December 30, 2007 and is expected to be recognized as compensation expense over a weighted average period of 1.46 years.

At December 31, 2006,
there were approximately 116,000 RSUs outstanding. The unrecognized stock-based compensation cost was $1.3 million at December 31, 2006 and was expected to be recognized as compensation expense over a weighted

|(1) | Aggregate intrinsic value for RSUs represents the closing price per share of our stock on December 30, 2007, multiplied by the number of non-vested RSUs expected to vest as of
December 30, 2007.
|--- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

For RSUs, stock-based compensation expense is calculated based on our stock price on the date of grant, multiplied
by the number of RSUs granted. The grant date fair value of RSUs, less estimated forfeitures, is recorded on a straight-line basis, over the vesting period.

In August 2007 and November 2007, we granted approximately 22,000 shares of performance based RSUs to certain executives, issuable on March 31, 2008. Based on our assessment of meeting the performance targets established for each
individual and the probability that these targets will be achieved, we recorded compensation expense of approximately $25,000 and $46,000, respectively, related to these grants for the three and nine months ended December 30, 2007.

During the three months ended December 30, 2007, we granted our former chief executive officer 5,000 shares of fully vested common stock after his three months
of service as per his employment agreement, and recorded approximately $45,000 as stock-based compensation expense.

NOTE 12. WARRANTS

In connection with our merger with Sipex, we assumed warrants to purchase of a total of approximately 280,000 shares of our common stock. The warrants are exercisable
at any time for shares of our common stock at an initial exercise price of $9.63 per share, subject to adjustment upon certain events. The warrants expire on May 18, 2011. As of December 30, 2007, there were approximately 280,000 warrants
outstanding.

NOTE 14. LEASE FINANCING OBLIGATION

In connection with our merger with Sipex, we assumed lease financing obligation related to a facility, located at 233 South Hillview Drive in Milpitas, California (the Hillview facility). The lease term
expires March 2011 with average lease payments of approximately $1.4 million per year.

The fair value of the Hillview facility was estimated at $13.4
million at the time of the merger and is included within property, plant and equipment on the condensed consolidated balance sheet. In connection with purchase accounting, we have accounted for this sale and leaseback transaction as a financing
transaction with the liability on the condensed consolidated balance sheet as long-term lease financing obligation. The effective interest rate is 8.2%. Depreciation for the Hillview facility is recorded over the straight-line method for
the remaining useful life.

Future minimum lease payments for the lease financing obligation as of December 30, 2007 are as follows (in thousands):

For the three and nine months ended December 30, 2007, interest expense totaled approximately $275,000 and
$367,000, respectively, for the lease financing obligation.

NOTE 15. COMMITMENTS AND CONTINGENCIES

In 1986, Micro Power Systems Inc. (MPSI), a subsidiary that we acquired in June 1994, identified low-level groundwater contamination at its principal
manufacturing site. Although the area and extent of the contamination appear to have been defined, the source of the contamination has not been identified. MPSI previously reached an agreement with a prior tenant to share in the cost of ongoing site
investigations and the operation of remedial systems to remove subsurface chemicals. The frequency and number of wells monitored at the site was reduced with prior regulatory approval for a plume stability analysis as an initial step towards site
closure. No significant rebound concentrations have been observed. The groundwater treatment system will remain shut down during calendar year 2008, for a two year plume stability evaluation.

On August 21, 2003, we signed an exclusive sourcing agreement with PolarFab, a US-based semiconductor foundry. We are under obligation to make minimum purchase
commitments based on quarterly rolling forecasts extending out to one year. We have also agreed to purchase no less than 50% of the rolling forecast on an ongoing basis through the term of this agreement. The initial term of the agreement is five
years with renewals on a negotiated basis. As of December 30, 2007, the purchase commitment with PolarFab was approximately $1.7 million for the next twelve months.

On February 27, 2006, we entered into a definitive Master Agreement with Silan, a China-based semiconductor foundry. This transaction was related to the closing Sipexs wafer fabrication operations located
in Milpitas, California. Under this agreement, Sipex and Silan would work together to enable Silan to manufacture semiconductor wafers using Sipexs process technology. The Master Agreement includes a Process Technology Transfer and License
Agreement which contemplates the transfer of eight of our processes and related product manufacturing to Silan. Once we confirm to Silan that the process qualification wafers and product qualification wafers (under a Wafer Transfer Agreement)
conform to its specifications, Silan would commence commercial manufacturing for us. Subject to our option to suspend in whole or in part, there is a purchase commitment under the Wafer Supply Agreement obligating us to purchase from Silan an
average of at least one thousand equivalent wafers per week, calculated on a quarterly basis, for two years. As of December 30, 2007, several CMOS (complementary metal oxide semiconductor) and all bipolar and BiCMOS (bipolar CMOS) product

##### Table of Contents

qualifications have been completed to our specifications. Additional CMOS product qualification testing is ongoing. As of December 30, 2007, the
purchase commitment was approximately $1.5 million.

Generally, we warrant all of our products against defects in materials and workmanship for a period
ranging from ninety days to two years from the delivery date. Reserve requirements are recorded in the period of sale and are based on an assessment of the products sold with warranty and historical warranty costs incurred. Our liability is limited
to either replacing, repairing or issuing credit, at our option, for the product if it has been paid for. The warranty does not cover damage which results from accident, misuse, abuse, improper line voltage, fire, flood, lightning or other damage
resulting from modifications, repairs or alterations performed other than by us, or resulting from failure to comply with our written operating and maintenance instructions. Warranty expense has historically been immaterial for our products. The
warranty liability related to our products was approximately $0.4 million at December 30, 2007.

Additionally, our sales agreements indemnify our
customers for any expenses or liability resulting from alleged or claimed infringements of any United States letter patents of third parties. However, we are not liable for any collateral, incidental or consequential damages arising out of patent
infringement. The terms of these indemnification agreements are perpetual, commencing after execution of the sales agreement or the date indicated on our order acknowledgement. The maximum amount of potential future indemnification is unlimited.
However, to date, we have not paid any claims or been required to defend any lawsuits with respect to any such indemnity claim.

NOTE 16. LEGAL
PROCEEDINGS

From time to time, we are involved in various claims, legal actions and complaints arising in the normal course of business. Although the
ultimate outcome of the matters discussed below and other matters is not presently determinable, management currently believes that the resolution of all such pending matters will not have a material adverse effect on our financial position, results
of operations or liquidity.

Ericsson Wireless Communication, Inc. and Vicor Corporation

On November 16, 2004, Ericsson Wireless Communications, Inc. (now known as Ericsson Inc.) initiated a lawsuit against us in San Diego County Superior Court. In its
Third Amended Complaint, Ericsson asserted causes of action against us for negligence, strict product liability, and unfair competition. Through its complaint, Ericsson sought monetary damages and unspecified injunctive relief. Based on discovery
responses, Ericssons claim for monetary damages included a claim for repair costs, a claim for damages to reimburse Ericsson for concessions made to customers and to complete a retrofit of its products, and lost profits. Ericsson claimed that
its damages exceed $1 billion. The case is based on Ericssons purchase of allegedly defective products from Vicor Corporation, our former customer to whom we sold untested, semi-custom wafers. We disputed the allegations in Ericssons
Third Amended Complaint, believed that we had meritorious defenses, and defended the lawsuit vigorously. On December 1, 2006, we entered into a Settlement Agreement with Ericsson, Inc. to resolve the claims asserted by Ericsson. Based on
further events in the case, our total liability to Ericsson under the Settlement Agreement was $500,000, which was paid by our insurance carriers. Following payment, Ericsson dismissed its claims against us with prejudice.

On April 5, 2005, Vicor filed a cross-complaint against us in San Diego County Superior Court. In the cross-complaint, Vicor alleged, among other things, that we
sold it integrated circuits that were defective and failed to meet agreed-upon specifications, and that we intentionally concealed material facts regarding the specifications of the integrated circuits that Vicor alleges it bought from us. In its
cross-complaint, Vicor alleged that it is entitled to indemnification from us for the damages that Vicor paid to Ericsson as a result of the causes of action asserted by Ericsson against Vicor. Vicor asserted causes of action against us for breach
of contract, breach of express contract warranty, breach of implied warranties of merchantability and fitness, breach of the covenant of good faith and fair dealing, fraud, negligence, strict liability, implied contractual indemnity, and equitable
indemnity. On May 9, 2005, we filed a demurrer to all but one of the indemnity causes of action in Vicors cross-complaint. On June 17, 2005, the San Diego Superior Court sustained our demurrer to all of Vicors causes of action
without leave to amend except the claims for implied contractual indemnity and equitable indemnity. We answered the two remaining causes of action on July 5, 2005. We disputed the allegations in Vicors cross-complaint, believed that we
had meritorious defenses, and defended the lawsuit vigorously. On December 1, 2006, we entered into a Settlement Agreement with Ericsson, Inc.

We
filed a motion for an order finding the Settlement Agreement that we entered with Ericsson was in good faith on December 20, 2006. On January 22, 2007, the Court entered an order finding that we entered into the Settlement Agreement in
good faith. The result of the finding of good faith was that Vicors indemnity claims were subject to dismissal. On February 13, 2007, Vicor filed a petition for writ of mandate with the California Court of Appeal challenging the good
faith finding. The Court of Appeal summarily denied Vicors petition on February 28, 2007. On July 10, 2007, the San Diego

##### Table of Contents

Superior Court dismissed Vicors indemnity claims and entered judgment in our favor. After entering judgment, the San Diego Superior Court awarded us
costs against Vicor in the amount of $84,405 and monetary sanctions against Vicor in the amount of $44,266.91. Vicor filed a notice of appeal on September 6, 2007. Vicor has yet to file its opening brief.

On March 4, 2005, we filed a complaint in Santa Clara County Superior Court against Vicor. In the complaint, we sought a declaration regarding the respective rights
and obligations, including warranty and indemnity rights and obligations, under the written contracts between us and Vicor for the sale of untested, semi-custom wafers. In addition, we sought a declaration that we were not responsible for any
damages that Vicor must pay to Ericsson or any other customer of Vicor arising from claims that Vicor sold allegedly defective products.

On March 17,
2005, Vicor filed a cross-complaint against us and Rohm Device USA, LLC and Rohm Co., Ltd, the owners and operators of the foundry which supplied the untested, semi-custom wafers that we sold to Vicor. In the cross-complaint, Vicor alleged, among
other things, that we sold it integrated circuits that were defective and failed to meet agreed-upon specifications, and that we intentionally concealed material facts regarding the specifications of the integrated circuits that Vicor alleges it
bought from us. In its cross-complaint, Vicor also alleges that it is entitled to indemnification from us for any damages that Vicor must pay to Ericsson and other Vicor customers as a result of the causes of action asserted by Ericsson in the San
Diego County action discussed above and any other claims that may be made against Vicor. In the cross-complaint, Vicor asserted causes of action against us for breach of contract, breach of express contract warranty, breach of implied warranties of
merchantability and fitness, breach of the covenant of good faith and fair dealing, fraud, negligence, strict liability, implied contractual indemnity, and equitable indemnity. On May 23, 2005, we filed a demurrer to each cause of action in
Vicors cross-complaint in Santa Clara County. On July 15, 2005, the Santa Clara County Superior Court sustained our demurrer to each of the causes of action asserted by Vicor. The Court granted Vicor leave to amend the cross-complaint to
assert a cause of action for declaratory relief only. On August 1, 2005, Vicor filed its amended cross-complaint seeking a declaration of the parties respective rights and obligations, including warranty and indemnity rights, under the
alleged contracts between us and Vicor for the sale of untested, semi-custom wafers. In addition, Vicor sought a declaration that we were obligated to indemnify it for any damages resulting from claims brought against Vicor by its customers. Vicor
has not sought damages in the Santa Clara County action. We answered Vicors amended cross-complaint on September 2, 2005. On April 10, 2006, Vicor moved to have the San Diego County action transferred to Santa Clara County and
coordinated with the action in Santa Clara County. On June 6, 2006, the Court deferred deciding Vicors motion until the Court in the San Diego County action could rule on a similar motion pending in that action. As discussed above, the
Court in the San Diego County action granted Ericssons motion to transfer and coordinate the Santa Clara County action with the San Diego County action in San Diego County. The Santa Clara County action has been transferred to San Diego
County. No trial date has been set. We do not believe that the litigation will have a material impact on our financial condition, results of operations, or liquidity.

DiPietro v. Sipex

In April 2003, Plaintiff Frank DiPietro (former CFO of Sipex Corp.) brought an action for breach
of contract against Sipex in the Middlesex Superior Court in the state of Massachusetts. Mr. DiPietro was seeking approximately $800,000 in severance benefits. Sipex counterclaimed for approximately $150,000, which it was owed under a
promissory note signed by Mr. DiPietro. In August 2004, Sipex filed two motions for summary judgment (one for Mr. DiPietros claims against it and one for its counterclaim against Mr. DiPietro). In June 2005, the Middlesex
Superior Court granted both Sipexs Motions for Summary Judgment. Soon thereafter, Mr. DiPietro filed a notice of appeal. Sipex then filed motions for costs and pre-judgment interest. Sipex was successful in its motion for prejudgment
interest and it was successful in requiring Mr. DiPietro to pay over $900 in deposition costs.

After these judgments, Sipex sought assurance from
Mr. DiPietro that he had assets to cover this judgment. When it did not receive a satisfactory response, it filed a motion for attachment. On November 15, 2005, the Court ordered that Mr. DiPietro post a bond in the amount of
$150,000. After some additional motion practice, Mr. DiPietro posted the bond.

Then, after judgment was formally entered in Superior Court, the clerk
of the Superior Court collected the docket and sent it to the Appeals Court of Massachusetts. On June 21, 2006, Mr. DiPietro served Sipex with his appeal brief. On July 20, 2006, Sipex served its Opposition and
Mr. DiPietros Reply Brief was served on August 3, 2006. On December 12, 2006, the Appeals Court heard arguments inDiPietro v. Sipex and asked for a letter clarifying a legal issue that Sipex provided on
December 28, 2006. On January 12, 2007, Mr. DiPietro sent a letter responding to Sipexs letter.

On May 14, 2007, the Appeals
Court issued its decision reversing the Superior Courts grant of summary judgment and remanding the case for further proceedings. Sipex immediately filed a motion for enlargement of time to file a Petition for Rehearing and an Application for
Further Appellate Review. Sipexs Petition for Rehearing was filed on June 13, 2007, in the Massachusetts Appeals Court and its Application for Further Appellate Review was filed on June 28, 2007, in the

Massachusetts Supreme Judicial Court. Thereafter, on July 9, 2007, DiPietro filed its Opposition to Sipexs Application for Further Appellate
Review and on July 18, 2007, filed his Response to Sipexs Petition for Rehearing. In early September 2007, the Appeals Court amended its decision to clarify issues addressed in Sipexs Petition for Rehearing.

Meanwhile, Mr. DiPietro filed a motion to release the bond he posted in early 2006 for the judgment amount due to the Appeals Court

decision. On October 11, 2007, a hearing was held in the Middlesex Superior Court on this issue and on October 22, 2007, the court allowed this motion and
Mr. DiPietros bond was released.

On October 31, 2007, Sipexs Application for Further Appellate Review was denied. The case was
remanded to Superior Court and will proceed forward.

Cypress v. Sipex, Exar and Ralph Schmitt

On October 12, 2007, Cypress Semiconductor Corporation (Cypress) filed an action against Sipex Corporation (Sipex), Exar Corporation
(Exar), Ralph Schmitt and Does 1 through 50 in the Superior Court of the State of California, County of Santa Clara, Cypress Semiconductor Corp. v. Sipex Corp., et al., Case No. 1-07-CV096311, alleging claims for:
(1) misappropriation of trade secrets ; (2) violation of the Computer Fraud and Abuse Act, 18 U.S.C. §1030; (3) unfair competition under Cal. Bus. & Prof. Code §§17200et seq .; (4) tortious
interference with contract; (5) interference with actual and prospective economic advantage; (6) breach of fiduciary duty and breach of the duty of loyalty; (7) inducement of breach of fiduciary duty; (8) breach of written
contract; (9) breach of the covenant of good faith and fair dealing; (10) conversion; and (11) unjust enrichment. The second, sixth, eighth and ninth causes of action are alleged against Mr. Schmitt only. Mr. Schmitt
was Chief Executive Officer and President and a member of the Board of Directors of Exar from August 25, 2007 to December 6, 2007. Prior to Exars merger with Sipex, he was Chief Executive Officer and a member of the Board of
Directors of Sipex. Exar filed an answer to the complaint on November 13, 2007. The case was removed to federal court on November 14, 2007, Cypress Semiconductor Corp. v. Sipex Corp., et al., United States District Court,
Northern District of California, Case No. C 07-05778 JF.

The case purportedly arises from Mr. Schmitts departure in June 2005 from Cypress,
where he was Executive Vice President, Sales and Marketing, and his subsequent employment by Sipex. Cypress claims that Mr. Schmitt took Cypress confidential information to Sipex and then Sipex hired Cypress employees, who also are alleged
to have taken Cypress confidential information to Sipex. Exar disputes the allegations in the complaint, believes it has meritorious defenses, and intends to defend the lawsuit vigorously. At this stage of the litigation and without additional
information, we are unable to determine the probability that the claims asserted by Cypress will result in liability. As of the date of this report, we do not believe that the litigation will have a material impact on our financial condition
results of operations or liquidity.

NOTE 17. INCOME TAXES

During the three months ended December 30, 2007 and December 31, 2006, we recorded an income tax provision of $1.7 and $0.4 million, respectively. During the nine months ended December 30, 2007 and December 31, 2006, we
recorded an income tax provision of $7.5 and $3.1 million, respectively. The increase in our income tax provision from December 31, 2006 reflects the establishment of an $8.3 million valuation allowance against all our deferred tax assets in
connection with our merger with Sipex as a result of our combined companies losses offset, in part, by benefits from lower pre-tax income. Our valuation allowance at December 30, 2007 is primarily attributable to Federal and state
deferred tax assets, as well as certain foreign deferred tax assets. We believe that sufficient uncertainty exists with regard to the realizability of these tax assets such that a valuation allowance is necessary. Factors considered in providing a
valuation allowance include the lack of a significant history of consistent profits and the lack of carry-back capacity to realize these assets. Based on the absence of objective evidence, we are unable to assert that it is more likely than not that
we will generate sufficient taxable income to realize these remaining net deferred tax assets.

Our effective tax rate for the three months ended
December 30, 2007 was (16.6%), primarily due to acquisition-related non-deductible identifiable intangible assets amortization and other non-deductible acquisition-related charges during the three months ended December 30, 2007.

Effective April 1, 2007, we adopted Financial Accounting Standards Interpretation No. 48, Accounting for Uncertainty in Income Taxes 
an interpretation of FASB Statement No. 109 (FIN 48). FIN 48 prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of uncertain tax positions taken or expected to be
taken in our income tax return, and also provides guidance on derecognition, classification, interest and penalties,

##### Table of Contents

accounting in interim periods, disclosure and transition.

The
cumulative effect of adopting FIN 48 was a decrease in the liability for uncertain tax positions and an increase of $0.2 million to the April 1, 2007 opening retained earnings balance. Upon adoption of FIN 48, the liability for uncertain
tax positions at April 1, 2007 was $0.8 million. Consistent with the provisions of FIN 48, we reclassified $0.8 million of income tax liabilities from current to non-current liabilities because payment of cash is not anticipated within one
year of the balance sheet date. In addition, we decreased current taxes payable and deferred tax assets by $3.5 million for unrecognized tax benefits which serve to reduce net operating loss and tax credit carryforwards.

The total amount of gross unrecognized tax benefits as of the April 1, 2007 adoption date of FIN 48 was $7.7 million. The unrecognized tax benefits increased
by $0.1 million and $3.2 million during the three and nine months ended December 30, 2007, respectively, to $11.0 million. The increase during the three months ended September 30, 2007 is primarily as a result of our merger with Sipex in
August 2007. If recognized, $1.2 million of these unrecognized tax benefits would be recorded as a reduction of future income tax provision.

Estimated
interest and penalties related to the income taxes are classified as a component of the provision for income taxes in the condensed consolidated statement of operations. Accrued interest and penalties were $0.1 million and $0.2 million as of
April 1, 2007 and December 30, 2007, respectively.

Our only major tax jurisdictions are the United States federal and various states. The fiscal
years 1997 through 2007 remain open and subject to examinations by the appropriate governmental agencies in the United States with fiscal years 2000 through 2007 open to audits in certain of our state jurisdictions.

For the three months ended December 30, 2007 and December 31, 2006, Alcatel-Lucent represented approximately
15% and 19%, respectively, of our net sales. For the nine months ended December 30, 2007 and December 31, 2006, Alcatel-Lucent represented 13% and 17%, respectively, of our net sales. No other direct customers accounted for 10% or greater
of our net sales in these periods.

Substantially all of our long-lived assets at December 30, 2007 and December 31, 2006 were located in the
United States.

NOTE 19. RECENTLY ISSUED ACCOUNTING STANDARDS

In December 2007, the FASB issued Statement of Financial Accounting Standards No. 141 (revised 2007) (SFAS No. 141R), Business Combinations, which replaces SFAS No 141. The statement retains the purchase method
of accounting for acquisitions, but requires a number of changes, including changes in the way assets and liabilities are recognized in the purchase accounting. It also changes the recognition of assets acquired and liabilities assumed arising from
contingencies, requires the capitalization of in-process research and development at fair value, and requires the expensing of acquisition-related costs as incurred. SFAS No. 141R is effective for financial statements issued for fiscal years
beginning after December 15, 2008 and will apply prospectively to business combinations completed on or after that date.

In February 2007, the FASB
issued Statement of Financial Accounting Standards No. 159, The Fair Value Option for Financial Assets and Financial Liabilities (SFAS No. 159). SFAS No. 159 permits companies to choose to measure certain financial
instruments and certain other items at fair value. The standard requires that unrealized gains and losses on items for which the fair value option has been elected be reported in earnings. SFAS 159 is effective for financial statements issued for
fiscal years beginning after November 15, 2007, although earlier adoption is permitted. We are currently evaluating the impact of implementing SFAS No. 159 on our financial position, results of operations and liquidity.

In September 2006, the FASB issued Statement of Financial Accounting Standards No. 157 (SFAS No. 157), Fair Value Measurements. SFAS
No. 157 defines fair value, establishes a framework and provides guidance regarding the methods used for measuring fair value, and expands disclosures about fair value measurements. SFAS No. 157 is effective for financial statements issued
for fiscal years beginning after November 15, 2007, and interim periods within those fiscal years. We are currently assessing the impact, if any, of adopting SFAS No. 157 on our financial position, results of operations and liquidity.

NOTE 20. SUBSEQUENT EVENTS

On January 16, 2008,
we entered into a sublease agreement of our Hillview facility located in Milpitas, California, which we originally leased from Mission West Properties, L.P. (See Note 14.) The sublease will start from April 15, 2008 and expires on
March 31, 2011, with an average annual rent of approximately $1.4 million. The agreement also requires the subtenant to pay certain operating costs associated with subleasing the facility.

On February 6, 2008, we acquired the exclusive rights to all of Fyrestorm Inc.s (Fyrestorm) intellectual property, including rights to thirty
patents related to digital predictive algorithms. Fyrestorm was a private venture-funded company that developed an all-digital adaptive loop control technology designed to enable efficient and extremely fast response switching-mode power supplies.
We paid approximately $3.2 million in cash for the right to the intellectual property.

Overview

Exar Corporation and its subsidiaries (Exar or we) are a fabless semiconductor company that designs, develops, markets and sells power management
and connectivity silicon solutions. Applying both analog and digital technologies, our products are deployed in a wide array of products such as portable electronic devices, set top boxes, digital video recorders, telecommunication systems and
industrial automation equipment. We have a broad portfolio of high-performance interface devices: Universal Asynchronous Receiver Transmitters (UARTs), serial transceivers and integrated combinations. Our UARTs offerings provide
customers with the low power, reduced space and increased bandwidth required for rapidly changing market demands. Building on this strong industry foundation, we also have a growing number of interface combination ICs that incorporate adjacent
device functions  RS232, RS485, or I2C  onto a single, highly integrated product. Our power management products, such as PowerBlox, regulators (boost and buck), charge pumps and controllers, provide measured levels of power to the
system, independent of normal operating changes and temperature fluctuations. Our products are designed to enable solutions that produce more power with higher efficiency, such as drivers for Light Emitting Diodes (LEDs) for consumer and
portable display monitors. Across the communications infrastructure, sophisticated data aggregation, transport and processing are done at the network switch, router and hub level by physical layer and access control solutions. We support this
critical requirement with proven devices spanning T1/E1 to SONET/SDH transmission speeds. We also offer advanced framers and mappers enabling high bandwidth data aggregation over SONET/SDH. Finally, we offer Serial Advanced Technology Attachment
(SATA) port multipliers/selectors that facilitate data deployment across varied storage environments.

We market our products worldwide with
sales offices and personnel located throughout the Americas, Europe, Asia, and Japan. Our products are sold in the United States through a number of manufacturers representatives and distributors. Internationally, our products are sold through
various regional and country specific distributors with locations in thirty-three countries around the globe. In addition to our sales offices, we also employ a worldwide team of field application engineers to work directly with our customers. These
international sales consist primarily of export sales from the United States that are denominated in U.S. Dollars. Such international related operations expenses expose us to fluctuations in currency exchange rates because our foreign operating
expenses are denominated in foreign currency while our sales are denominated in U.S. Dollars. Although foreign sales within certain countries or foreign sales comprised of certain products may subject us to tariffs, our gross profit margin on
international sales, adjusted for differences in product mix, is not significantly different from that realized on our sales to domestic customers. Our operating results are subject to quarterly and annual fluctuations as a result of several factors
that could materially and adversely affect our future profitability as described in Risk Factors under Part II, Item 1A.

On
August 25, 2007, Sipex Corporation (Sipex) became a wholly owned subsidiary of Exar and each share of Sipex common stock issued and outstanding immediately prior to the effective time of the merger was converted into 0.6679 shares
of our common stock. Approximately 16.5 million shares of our common stock were issued to former Sipex stockholders in connection with the merger.

Sipex designed, manufactured and marketed high performance, analog integrated circuits (ICs) used by original equipment manufacturers (OEMs), in the computing, consumer electronics, communications and networking
infrastructure markets. The merger was accounted for as a purchase. Accordingly, the results of operations of Sipex and estimated fair value of assets acquired and liabilities assumed are included in our condensed consolidated financial statements
beginning August 26, 2007.

Subsequent Events

Please refer to Note 20 of Notes to our condensed consolidated financial statements included in Item 1 of Part I for a discussion of the subsequent events involving sublease agreement of our Hillview facility and the purchase of
Fyrestorm Inc.s intellectual property, which are incorporated herein by reference.

Critical Accounting Policies and Use of Estimates

The preparation of our financial statements and accompanying disclosures in conformity with GAAP, the accounting principles generally accepted in the United States, requires estimates and assumptions that affect the
reported amounts of assets, liabilities, revenues and expenses, and related disclosures of contingent assets and liabilities in financial statements and the accompanying notes. The U.S. Securities and Exchange Commission (SEC) has
defined a companys critical accounting policies as policies that are most important to the portrayal of a companys financial condition and results of operations, and which require a company to make its most difficult and subjective
judgments, often as a result of the need to make estimates of matters that are inherently uncertain. Based on this definition, we have identified our most critical accounting policies and estimates to be as follows: (1) net sales;
(2) reserves for excess inventories; (3) income taxes; (4) non-marketable equity securities; and (5) stock-based compensation. Although we believe that our estimates, assumptions and judgments are reasonable, they are based upon
information presently available. Actual results may differ significantly from these estimates if the assumptions, judgments and conditions upon which they are based turn out to be inaccurate. A further discussion can be found in Item 7,
Managements Discussion and Analysis of Financial Condition and Results of Operations, of our Annual Report on Form 10-K for the fiscal year ended March 31, 2007. Our accounting policy for revenue recognition is described below
to emphasize our revenue recognition to distributors. Our accounting policy for income taxes, which changed in the first quarter of fiscal year 2008 in connection with adoption of the Financial Accounting Standards Interpretation No. 48
Accounting for Uncertainty in Income Taxes  an interpretation of FASB Statement No. 109 (FIN 48), is described below.

Prior
to our merger with Sipex in August 2007, the functional currency of each of our foreign subsidiaries was the local currency of that country. During the three months ended December 30, 2007, in connection with integrating and realigning our
combined operations, we reassessed the economic facts and circumstances of each of our foreign subsidiaries. As a result, during the three months ended December 30, 2007, the functional currencies for our foreign subsidiaries were changed to
the U.S. Dollar. Accumulated other comprehensive loss reported in the condensed consolidated balance sheet before December 1, 2007 included approximately $20,000 related to the cumulative foreign currency translation adjustment of our
subsidiaries prior to changing our functional currency.

The accounts of foreign subsidiaries have been remeasured into U.S. Dollars in accordance with the
Financial Accounting Standards Board (FASB) Statement of Financial Accounting Standards No. 52, Foreign Currency Translation(SFAS No. 52). Accordingly, foreign currency is remeasured to U.S. Dollars
for financial purposes by using the U.S. Dollar as the functional currency and exchange gains and losses are reported in income and expenses. These currency gains or losses are reported in interest and other income, net in the condensed
consolidated statements of operations. Monetary balance sheet accounts are remeasured using the current exchange rate in effect at the balance sheet date, for assets and liabilities, and for non-monetary items, the accounts are remeasured at the
historical exchange rate. Revenues and expenses are remeasured at the average exchange rates for the period.

Revenue Recognition

We recognize revenue in accordance with SEC Staff Accounting Bulletin 104, Revenue Recognition (SAB 104). SAB 104 requires that four basic criteria
must be met before revenue can be recognized: (1) persuasive evidence of an arrangement exists; (2) delivery has occurred or services rendered; (3) the price is fixed or determinable; and (4) collectibility is reasonably assured.

We derive revenue from the sale of our products principally to distributors and OEMs or their contract manufacturers. Our delivery terms are primarily FOB
shipping point, at which time title and all risks of ownership are transferred to the customer. For the three and nine months ended December 30, 2007, approximately 25% and 31%, respectively, of our net sales were derived from product sales to
our two primary distributors, Future Electronics Inc. (Future) and Nu Horizon Electronics Corp. (Nu Horizons). Approximately 75% and 69%, respectively, of our net sales were derived from product sales to other distributors,
OEM customers and other non-distributors.

Non-distributors:

For non-distributors, revenue is recognized when title to the product is transferred to the customer, which occurs upon shipment or delivery, depending upon the terms of the customer order, provided that persuasive
evidence of a sales arrangement exists, the price is fixed or determinable, title has transferred, collection of the resulting receivables is reasonably assured, there are no customer acceptance requirements, and there are no remaining significant
obligations. Provisions for returns and allowances for non-distributor customers are provided at the time product sales are recognized. An allowance for sales returns and allowances for customers is recorded based on historical experience or
specific

identification of an event necessitating an allowance.

Distributors:

Our two primary distributors agreements permit the return of 3% to 5% of their purchases during the preceding
quarter for purposes of stock rotation. For one of these distributors, a scrap allowance of 2% of the proceeding quarters purchases is permitted. We also provide discounts to certain distributors based on volume of product ordered for a
specific product with a specific volume range for a given customer over a period not to exceed one year.



| |  | Sell-in Basis: Revenue is recognized upon shipment if we conclude we can reasonably estimate the credits for returns, pricing allowances and/or other
concessions. We record an estimated allowance, at the time of shipment, based upon historical patterns of returns, and pricing allowances and other concessions (i.e., sell-in basis).
|- |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | Sell-through Basis: Revenue and the related costs of sales is deferred until the resale to the end customer if we grant more than limited rights of
returns, pricing allowance and/or other concessions or if we cannot reasonably estimate the level of returns and credits issuable (i.e., sell-through basis). Under the sell-through basis, accounts receivable are recognized and inventory
is relieved upon shipment to the distributor as title to the inventory is transferred upon shipment, at which point we have a legally enforceable right to collection under normal terms. The associated sales and cost of sales are deferred by
recording deferred income (gross profit margin on these sales) as shown on the face of the condensed consolidated balance sheet. When the related product is sold by our distributors to their end customers, at which time the ultimate
price we receive is known, we recognize previously deferred income as sales and cost of sales.

Our historical patterns of returns,
pricing allowances and other concessions with distributors have been fairly consistent, which has enabled us to reasonably estimate such allowances at the time of shipment. Therefore, we have historically recognized revenue on sales to all
distributors on a sell-in basis and recorded an estimated allowance, at the time of shipment, based on authorized and historical patterns of returns and other concessions. Concurrent with the merger with Sipex, we reassessed our ability to continue
to reasonably estimate such allowances for each of our distributors as well as for Sipexs distributors. Prior to the merger, Sipex recognized revenue on sales to all distributors on a sell-through basis. Consistent with Sipexs past
practice, we have concluded that we are not able to reasonably estimate such allowances at the time of shipment of products to Sipexs distributors. Therefore, we have determined that consistent with Sipexs past practice, we will continue
to recognize sales to Sipexs distributors on sell-through basis. In addition, as a result of the merger, our relationships, marketing and sales practices with our two primary distributors have changed. Further, as disclosed in Note 3 of the
Notes to our condensed consolidated financial statements, Future is now a related party to Exar. As a result of these changes, we have concluded that we can no longer reasonably estimate returns, pricing allowances and other concessions at the time
of shipment of products to these distributors. Accordingly, as of August 26, 2007, we determined it was appropriate that revenue on all sales to Future and Nu Horizons be recognized on a sell-through basis.

As a result of revenue on sales to our two primary distributors now being recognized on a sell-through basis, $6.5 million of revenue and $1.5 million of related cost of
sales is deferred at December 30, 2007, and is included within Deferred income and Deferred income, related party, on the condensed consolidated balance sheet.

Accounting for Uncertainty in Income Taxes

Effective April 1, 2007, we adopted FIN 48. FIN 48 prescribes a
recognition threshold and measurement attribute for the financial statement recognition and measurement of uncertain tax positions taken or expected to be taken in our income tax return, and also provides guidance on derecognition, classification,
interest and penalties, accounting in interim periods, disclosure, and transition.

The cumulative effect of adopting FIN 48 was a decrease in the
liability for uncertain tax positions and an increase of $0.2 million to the April 1, 2007 opening retained earnings balance. Upon adoption, the liability for uncertain tax positions at April 1, 2007 was $0.8 million. Consistent
with the provisions of FIN 48, we reclassified $0.8 million of income tax liabilities from current to non-current liabilities because payment of cash is not anticipated within one year of the balance sheet date. In addition, we decreased current
taxes payable and deferred tax assets by $3.5 million for unrecognized tax benefits which serve to reduce net operating loss and tax credit carryforwards.

The total amount of gross unrecognized tax benefits as of the April 1, 2007 adoption date was $7.7 million. The unrecognized tax benefits increased by $0.1 million and $3.2 million during the three and nine months ended
December 30, 2007, respectively, to $11.0 million. The increase during the three months ended September 30, 2007 was primarily as a result our merger with Sipex in August 2007. If recognized, $1.2 million of these unrecognized tax benefits
would be

recorded as a reduction of future income tax provision.

Estimated interest and penalties related to the income taxes are classified as a component of the provision for income taxes in the condensed consolidated statement of operations. Accrued interest and penalties were $0.1 million and
$0.2 million as of April 1, 2007 and December 30, 2007, respectively.

Our major tax jurisdictions are the United States federal and various
states. The fiscal years 1997 through 2007 remain open and subject to examinations by the appropriate governmental agencies in the United States with fiscal years 2000 through 2007 open to audits in certain of our state jurisdictions.

The application of income tax law is inherently complex. Tax laws and regulations are at times ambiguous, and interpretations of and guidance regarding income tax laws
and regulations change over time. This requires us to make many subjective assumptions and judgments regarding our income tax exposure. Changes in our assumptions and judgments can materially affect our consolidated financial position, results of
operations and cash flows.

Results of Operations

For
the periods indicated, the following table shows certain cost, expense and other income items as a percentage of net sales. The table and subsequent discussion should be read in conjunction with the condensed consolidated financial statements and

Interface

Interface products include UARTs, video, imaging and other products as well as transceiver products acquired in the merger with Sipex.

Net sales
of interface products for the three and nine months ended December 30, 2007 include $4.6 million and $5.6 million, respectively, in net sales of products acquired in the merger. Furthermore, as a result of transitioning revenue recognition for
our two primary distributors to a sell-through basis as of August 26, 2007, we estimate the net sales of our UARTs for the three and nine months ended December 30, 2007 were lower by $3.3 million and $4.9 million, respectively, as compared
to the same periods a year ago.

In addition, net sales of UARTs for the three and nine months ended December 30, 2007 when compared to similar prior
periods, decreased due to a shift in mix to lower priced products and lower prices for certain products.

Communications

Communication products include network access and transmission products, storage products, as well as optical products acquired in the merger with Sipex.

Net sales of communications products for the three and nine months ended December 30, 2007 include $0.7 million and $0.9 million, respectively, in net sales of
products acquired in the merger. Furthermore, as a result of transitioning revenue recognition for our two primary distributors to the sell-through basis as of August 26, 2007, we estimate communication products net sales for the three and nine
months ended December 30, 2007 were lower by $0.7 million and $1.2 million, respectively, as compared to the same periods a year ago.

Power
Management

Power management products were acquired in the merger with Sipex and increased net sales for the three and nine months ended
December 30, 2007 by $5.5 million and $7.3 million, respectively.

Sales by Channel and Geography

The following table shows net sales by channel in absolute dollars and as a percentage of net sales for the periods indicated (in thousands):

Net sales to our two primary distributors, Future and Nu Horizons for the three months and nine months ended
December 30, 2007 includes $2.8 million and $3.2 million in sales, respectively, of the products acquired in the merger. Furthermore, as a result of transitioning revenue recognition for our two primary distributors as of August 26, 2007,
we estimate net sales for the three and nine months ended December 30, 2007 were lower by $4.0 million and $6.1 million, respectively.

Net sales in the United States for the three and nine months ended December 30, 2007, includes $1.4 million
and $1.8 million, respectively, in sales of products acquired in the merger. Furthermore, as a result of transitioning revenue recognition for our two primary distributors to a sell-through basis as of August 26, 2007, we estimate net sales for
the three and nine months ended December 30, 2007 were lower by $4.0 million and $6.1 million, respectively.

Net sales in international markets for
the three and nine months ended December 30, 2007, includes $9.4 and $11.9 million, respectively, of sales of products acquired in the merger.

Gross profit represents net sales less cost of sales. Cost of sales includes:



| |  |  | the cost of purchasing the finished silicon wafers manufactured by independent foundries;
| | - |  | -----------------------------------------------------------------------------------------



| |  |  | costs associated with assembly, packaging, testing, quality assurance and product yields;
| | - |  | -----------------------------------------------------------------------------------------



| |  |  | the cost of personnel and related stock-based compensation expense, and cost of equipment associated with manufacturing support and manufacturing engineering;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the amortization of purchased intangible assets;
| | - |  | ------------------------------------------------



| |  |  | the amortization of the fair value adjustment to acquired inventories in accordance with purchase accounting ; and
| | - |  | ------------------------------------------------------------------------------------------------------------------



| |  |  | provisions for excess and obsolete inventory.
| | - |  | ---------------------------------------------

The
decrease in gross profit for the three and nine months ended December 30, 2007, was primarily due to incremental amortization expense of $2.3 million and $3.2 million, respectively, associated with the purchased intangible assets as a result of
the merger with Sipex, the amortization of the fair value adjustment to acquired inventories of $1.5 million and $1.8 million, respectively, and the sales of Sipexs products which have lower gross margins. The amortization expense for the same
period a year ago was $0.2 million and $0.7 million, respectively.

Stock-based compensation expense recorded in cost of sales was $0.4 million and $0.5
million, respectively, for the three and nine months ended December 30, 2007, as compared to $23,000 and $77,000, respectively for the same periods a year ago. The increase in stock-based compensation expense when compared to the same periods a
year ago is primarily

attributable to assumed unvested stock options in connection with the Sipex merger.

We anticipate that gross profit will continue to fluctuate due to, among other factors, future fluctuations in net sales, product mix, manufacturing costs, competitive pricing, manufacturing yields, excess and
obsolete inventory, merger related expenses, the recognition of the synergy benefits, the reduction of the amortization of the fair value adjustment to acquired inventories and future amortization of any additional license technology.

Research and development expenses consist primarily of:



| |  |  | salaries, stock-based compensation and related expenses of engineering employees engaged in product research, design and development activities;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | costs related to engineering design tools, mask tooling costs, test hardware, engineering supplies and services, and the use of in-house test equipment; and
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | facility expenses.
| | - |  | ------------------

The increase in R&D expenses
for the three and nine months ended December 30, 2007, as compared to the same period a year ago, was primarily a result of an incremental expense of $2.4 and $3.6 million, respectively, due to our merger with Sipex, $0.3 million in severance
costs of our employees, partially offset by lower labor related costs.

Stock-based compensation expense recorded in R&D expenses was $0.4 million and
$0.9 million, respectively, for the three and nine months ended December 30, 2007, as compared to $0.3 million and $1.0 million, respectively, for the same periods a year ago.

We believe that innovation is critical to our long-term success, and we intend to continue our investments in R&D to enhance our product offerings in order to meet the current and future requirements of our
customers and markets. Some aspects of our R&D efforts require significant short-term expenditures, such as mask tooling for new products, the timing of which may cause significant fluctuations in our R&D expenses. In addition, we expect
R&D expenses to fluctuate with merger related expenses, the licensing of intellectual property, the recognition of the synergy benefits and potential costs of discontinuing certain product development efforts as we optimize our R&D projects.
We are rationalizing our R&D projects with the intent of lowering spending from our most recent levels.

Selling, General and Administrative
(SG&A)

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

The increase in SG&A
expenses for the three and nine months ended December 30, 2007, as compared to the same period a year ago, was primarily attributable to an incremental expenses of $5.2 million and $6.6 million, respectively, due to our merger with Sipex,
merger related costs of $0.5 million and $1.3 million, respectively, and the amortization of acquired Sipex intangible assets of $0.5 million and $0.7 million, respectively, partially offset by lower labor related expenses.

We recorded $0.5 million separation expenses associated with our former chief executive officer in December 2007. In September 2006, we recorded $0.7 million separation
expenses associated with our former chief financial officer.

Stock-based compensation expense recorded in SG&A expenses was $1.0 million and $2.5
million for the three and nine months ended December 30, 2007, as compared to $0.7 million and $2.2 million for the same periods a year ago. The increase in stock-based compensation expense when compared to the same periods a year ago is
primarily attributable to assumed unvested stock options in connection with the Sipex merger.

We anticipate that SG&A expenses will continue to
fluctuate due to sales commissions, costs associated with business development, integration costs, amortization of acquired intangible assets, merger related expenses, the recognition of synergy benefits and professional fees. In the short term,
many of the SG&A expenses are fixed; however, we expect SG&A expense will continue to fluctuate.

Acquired In-Process Research and Development:

We recorded a charge of $8.8 million in acquired in-process research and development (IPR&D), associated with the merger with
Sipex in the three months ended September 30, 2007, we allocated the purchase price related to IPR&D through established valuation techniques with the assistance of a third-party service provider. IPR&D was expensed upon acquisition
because technological feasibility had not been established and no future alternative uses existed. The fair value of technology under development is determined using the income approach, which discounts expected future cash flows to present value,
taking into account the stage of completion, estimated costs to complete, utilization of patents and core technology, the risks related to successful completion, and the markets served. The cash flows derived from the IPR&D were discounted at
discount rates ranging from 25% to 40%. The percentage of completion for these projects ranged from 20% to 87% at the merger date.

The IPR&D projects
underway at Sipex at the merger date were in the interface and power management product families. Within interface, specific projects relate to new products in its Multiprotocol and RS485 families. Within power management, development activities
relate to the commercialization of its digital power technology, LED drivers, DC-DC regulators and controllers. All of these projects require further development and testing to bring them up to production. IPR&D projects for interface are
expected to require $0.8 million to complete with expected revenue generation beginning in mid calendar year 2008. IPR&D projects for power management are expected to require $2.2 million to complete. Product shipments of the IPR&D for the
power management began in late calendar year 2007.

If the projects discussed above are not successfully developed and/or successfully marketed, our sales
and profitability may be adversely affected in future periods.

Restructuring

During the three months ended December 30, 2007, we recorded an additional liability of $454,000 in connection with the Billerica lease termination.

For the three and nine months ended December 30, 2007, we paid cash severance of approximately $229,000 and $248,000, respectively, to the employees. The remaining balance of approximately $789,000 for severance
costs is expected to be paid

out in the next nine months.

For the three and nine months
ended December 30, 2007, we utilized approximately $391,000 and $502,000, respectively, of our restructuring accrual, primarily related to moving expenses at our Hillview facility and the lease expenses for the unused portion of the Billerica
facility in Massachusetts. The remaining balance of approximately $1.2 million is expected to be paid during the remaining terms of the lease contracts which extend through 2012.

See Note 4 of the Notes to our condensed consolidated financial statements in Item 1 of Part I for more information about the restructuring actions we have taken in fiscal year 2008.

Interest income and other income, net primarily consists of:



| |  |  | interest income;
| | - |  | ----------------



| |  |  | interest expense;
| | - |  | -----------------



| |  |  | realized gains on marketable securities;
| | - |  | ----------------------------------------



| |  |  | foreign exchange gains and losses; and
| | - |  | --------------------------------------



| |  |  | realized gains or losses resulting from investments in non-marketable equity securities and venture funds.
| | - |  | ----------------------------------------------------------------------------------------------------------

The decrease in interest income and other, net of $0.9 million during the three months ended December 30, 2007, as compared to the same period a year ago, was
primarily attributable to lower interest income as a result of lower investment balances, a charge associated with an other-than-temporary impairment of the Skypoint portfolio and interest expense on our lease financing obligation. The increase in
interest income and other, net of $0.1 million, during the nine months ended December 30, 2007, as compared to the same period a year ago, was primarily attributable to higher interest income as a result of increased interest rates.

We expect that our interest income will continue to fluctuate due to changes in interest rates and reduced investment balances as we continue to repurchase our stock.

Provision for Income Taxes

During the three months
ended December 30, 2007 and December 31, 2006, we recorded an income tax provision of $1.7 and $0.4 million, respectively. During the nine months ended December 30, 2007 and December 31, 2006, we recorded an income tax provision
of $7.5 and $3.1 million, respectively. The increase in our income tax provision from December 31, 2006 reflects the establishment of an $8.3 million valuation allowance against all our deferred tax assets in connection with our merger wit
Sipex as a result of our combined companies losses offset, in part, by benefits from lower pre-tax income. Our valuation allowance at September 30, 2007 is primarily attributable to Federal and state deferred tax assets, as well as
certain foreign deferred tax assets. We believe that sufficient uncertainty exists with regard to the realizability of these tax assets such that a valuation allowance is necessary. Factors considered in providing a valuation allowance include the
lack of a significant history of consistent profits and the lack of carry-back capacity to realize these assets. Based on the absence of objective evidence, we are unable to assert that it is more likely than not that we will generate sufficient
taxable income to realize these remaining net deferred tax assets.

##### Table of Contents

Our effective tax rate for the three months ended December 30, 2007 was (16.6%), primarily due to
acquisition-related non-deductible identifiable intangible assets amortization and other non-deductible acquisition-related charges during the three months ended December 30, 2007.

Liquidity and Capital Resources

We do not have any off-balance sheet arrangements, investments in special purpose
entities, variable interest entities or undisclosed borrowings or debt. Additionally, we are not a party to any derivative contracts, nor do we have any synthetic leases. At December 30, 2007, we had no foreign currency contracts outstanding.

Our principal sources of liquidity during the nine months ended December 30, 2007 were cash and cash equivalents and short-term marketable
securities, which, in the aggregate, decreased by $52.7 million to $303.4 million at December 30, 2007 from $356.1 million at March 31, 2007. Cash and cash equivalents increased by $36.1 million during the nine months ended
December 30, 2007, resulting primarily from net cash provided by operating activities of $10.4 million and investing activities of $85.7 million and partially offset by net cash used in financing activities of $59.9 million.

Operating Activities

Net cash provided by operating activities
totaled $10.4 million during the nine months ended December 30, 2007 as compared to net cash provided by operating activities of $15.2 million during the nine months ended December 31, 2006.

For the nine months ended December 30, 2007, net cash provided by operating activities resulted from a net loss of $23.5 million, an $8.8 million IPR&D non-cash
charge from the merger with Sipex, an $18.1 million in non-cash charges for depreciation and amortization expense, stock-based compensation, tax benefit from stock plans, the provision for sales returns and allowances, and impairment charge on
long-term investments, an increase in accounts receivable of $8.7 million, a decrease in accounts payable and accrued expense of $2.8 million, a decrease of income tax payable of $3.7 million, an increase in prepaid expense and other assets of $1.1
million, partially offset by a reduction in inventory of $1.0 million, an increase in accrued compensation and related benefits of $2.8 million; an increase in deferred income of $8.1 million and a decrease in deferred income tax assets of $11.4
million.

For the nine months ended December 31, 2006, net cash from operating activities resulted from net income of $6.8 million and $11.8 million
in non-cash charges for depreciation and amortization expense, stock-based compensation, tax benefit from stock plans, the provision for sales returns and allowances, and an impairment charge on long-term investments. These sources of cash were
partially offset by increases in prepaid expenses and other assets and accounts receivable of $1.3 million and $1.1 million, respectively.

Investment
Activities

Net cash provided by investing activities totaled $85.7 million during the nine months ended December 30, 2007 as compared to net cash
used in investing activities of $97.3 million during the nine months ended December 31, 2006.

During the nine months ended December 30, 2007,
our investing activities included proceeds from the sales and maturities of $381.4 million of short-term marketable securities, offset by purchases of short-term marketable securities of $290.9 million, purchases of property, plant, equipment and
intellectual property of $1.4 million, and net merger transaction costs of $2.9 million. The decreased holdings of short-term marketable securities were primarily due to our repurchase of approximately $58.0 million stock during the period.

As of December 30, 2007, we had a remaining obligation to make a capital contribution of $0.9 million to the Skypoint Fund upon its request. To meet
our capital commitment to the Skypoint Fund, we may need to use our existing cash, cash equivalents and/or short-term marketable securities.

During the
nine months ended December 31, 2006, our investing activities included the purchase of short-term marketable securities of $226.3 million and purchases of property, plant and equipment and other assets of $2.8 million partially offset by
proceeds from the sales and maturities of $132.5 million of short-term marketable securities.

Financing Activities

Net cash used in financing activities totaled $59.9 million in the nine months ended December 30, 2007, as compared to net cash provided by financing activities of
$11.7 million in the nine months ended December 31, 2006.

##### Table of Contents

During the nine months ended December 30, 2007, our financing activities reflected primarily the repurchases of our
common stock totaling $58.0 million and $5.3 million payment of bank borrowings assumed from the merger with Sipex, partially offset by the proceeds from the exercises of stock options under our stock option plans of $3.4 million.

On August 31, 2007, we established a new share repurchase plan (2007 SRP) and authorized the repurchase of up to $100 million of our common stock over
the next twelve months. The 2007 SRP was in addition to a share repurchase plan announced in March 2001 (2001 SRP), which covered the repurchase of up to $40 million of our common stock The shares repurchased under the 2001 SRP fully
utilized the $40 million authorization at December 30, 2007. As of December 30, 2007, the remaining authorized amount for stock repurchase under the 2007 SRP was $60.3 million with no termination date.

During the three and nine months ended December 30, 2007, we repurchased a total of 2.3 million and 4.7 million shares, respectively, of our common stock
at an aggregate cost of $25.6 million and $58.0 million, respectively, under the 2007 SRP and 2001 SRP.

To date, inflation has not had a significant
impact on our operating results.

We anticipate that we will continue to finance our operations with cash flows from operations, existing cash and
investment balances. We believe that our cash and cash equivalents, short-term marketable securities and cash flows from operations will be sufficient to satisfy working capital requirements and capital equipment needs for at least the next 12
months. However, should the demand for our products decrease in the future, the availability of cash flows from operations may be limited, thus possibly having a material adverse effect on our financial condition or results of operations. From time
to time, we evaluate potential acquisitions, strategic arrangements complementary to our business strategy. To the extent that we pursue or position ourselves to pursue these transactions, we could consume a significant portion of our capital
resources or choose to seek additional equity or debt financing. There can be no assurance that additional financing could be obtained on terms acceptable to us.

|ITEM 3. | QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
|------- | ----------------------------------------------------------

Foreign Currency Fluctuations

We are exposed to foreign currency fluctuations primarily through our foreign operations. This exposure is
the result of foreign operating expenses being denominated in foreign currency. Operational currency requirements are typically forecasted for a three-month period. If there is a need to hedge this risk, we may enter into transactions to purchase
currency in the open market or enter into forward currency exchange contracts.

If our foreign operations forecasts are overstated or understated during
periods of currency volatility, we could experience unanticipated currency gains or losses. At December 30, 2007, we did not have significant foreign currency denominated net assets or net liabilities, and had no foreign currency contracts
outstanding.

Interest Rate Sensitivity

We maintain
investment portfolio holdings of various issuers, types and maturity dates with various banks and investment banking institutions. The market value of these investments on any given day during the investment term may vary as a result of market
interest rate fluctuations. This exposure is not hedged because a hypothetical 10% movement in interest rates during the investment term would not likely have a material impact on investment income. The actual impact on investment income in the
future may differ materially from this analysis, depending on actual balances and changes in the timing and the amount of interest rate movements.

Short-term investments are classified as available-for-sale securities and the cost of securities sold is based on the specific identification method. At December 30, 2007, short-term investments consisted of United States
government and corporate securities of $147.5 million. At December 30, 2007, the difference between the fair value and the underlying cost of such investments was an unrealized gain of $1.1 million, before income taxes.

Our net income is dependent on, among other factors, interest income. If interest rates decline, our net income may be negatively impacted.

|ITEM 4. | CONTROLS AND PROCEDURES
|------- | -----------------------

Evaluation of Disclosure Controls and
Procedures (Disclosure Controls).

We evaluated the effectiveness of the design and operation of our Disclosure Controls, as defined by the
rules and regulations of the SEC (the Evaluation), as of the end of the period covered by this Form 10-Q. This Evaluation was performed under the supervision and with the participation of management, including our Chief Executive Officer
(the CEO), as principal executive officer, and Chief Financial Officer (the CFO), as principal financial officer.

Attached as
Exhibits 31.1 and 31.2 of this Report are the certifications of the CEO and the CFO in compliance with Section 302 of the Sarbanes-Oxley Act of 2002 (the Certifications). This section of the Report provides information concerning
the Evaluation referred to in the Certifications and should be read in conjunction with the Certifications.

Disclosure Controls are controls and
procedures designed to ensure that information required to be disclosed in the reports filed under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported within the time periods as specified in the
SECs rules and forms. In addition, Disclosure Controls are designed to allow for the accumulation and communications of information to our management, including the CEO and CFO, to allow timely decisions regarding required disclosures.

Based on the Evaluation, our CEO and CFO have concluded that our Disclosure Controls are effective as of December 30, 2007.

Inherent Limitations on the Effectiveness of Disclosure Controls.

Our management, including the CEO and CFO, does not expect that the Disclosure Controls will prevent all errors and all fraud. Disclosure Controls, no matter how well conceived, managed, utilized and monitored, can provide only reasonable
assurance that the objectives of such controls are met. Therefore, because of the inherent limitation of Disclosure Controls, no evaluation of such controls can provide absolute assurance that all control issues and instances of fraud, if any,
within us have been detected.

Changes in Internal Control over Financial Reporting

At August 25, 2007, Sipex had material weaknesses in its internal controls and procedures over financial reporting. We are currently in the process of integrating Exars and Sipexs internal controls
and procedures, and therefore, have excluded Sipexs controls and procedures over financial reporting from our assessment of internal controls as of December 30, 2007. At this time, we intend to include Sipex in our fiscal 2008 management
report, under Section 404 of the Sarbanes-Oxley Act of 2002.

Other than described above, there has been no change in our internal control over
financial reporting that occurred during the period covered by this Quarterly Report on Form 10-Q that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II  OTHER INFORMATION



|ITEM 1. | LEGAL PROCEEDINGS
|------- | -----------------

Please refer to Note 16 of Notes to our
condensed consolidated financial statements included in Item 1 of Part I for discussions of the legal proceedings, which are incorporated herein by reference.



|ITEM 1A. | RISK FACTORS
|-------- | ------------

If we are not able to successfully integrate,
operate and manage the combined company resulting from our recent merger with Sipex, we may fail to realize the expected benefits of the merger, which could have a material adverse effect on our business, financial condition and operating results.

Our merger with Sipex, which was effective on August 25, 2007, resulted in the combination of two previously independent public companies and
may require a long period of integration to realize all of the benefits we hope to achieve with the merger. Although we expect considerable benefits as a result of the merger, we will need to effectively address



37



---

##### Table of Contents

significant challenges to realize these expected benefits and synergies of the merger and there can be no assurance that we will actually realize any of
these anticipated benefits. The integration of companies is a complex, time-consuming and expensive process that could disrupt our business and divert our managements focus and resources from the day-to-day operation of the business to matters
relating to the post merger consideration. Integration over multiple geographies throughout the world presents even greater challenges. These challenges include but are not limited to:



| |  |  | integrating the management teams, strategies, cultures and operations of the two companies;
| | - |  | -------------------------------------------------------------------------------------------



| |  |  | retaining and assimilating the key personnel of each company;
| | - |  | -------------------------------------------------------------



| |  |  | integrating sales, engineering, operations, marketing, information technology and business management;
| | - |  | ------------------------------------------------------------------------------------------------------



| |  |  | retaining and maintaining relationships with existing customers, distributors and other partners of each company;
| | - |  | -----------------------------------------------------------------------------------------------------------------



| |  |  | achieving enterprise synergies;
| | - |  | -------------------------------



| |  |  | managing multiple geographic locations;
| | - |  | ---------------------------------------



| |  |  | integrating purchasing and procurement and retaining the main sources of supply and/or services of both companies;
| | - |  | ------------------------------------------------------------------------------------------------------------------



| |  |  | integrating the business process and related information technology applications and infrastructure of the two companies;
| | - |  | -------------------------------------------------------------------------------------------------------------------------



| |  |  | developing new products and services that optimize the assets and resources of both companies;
| | - |  | ----------------------------------------------------------------------------------------------



| |  |  | coordinating research and development activities to enhance the timely development of new products and technologies; and
| | - |  | ------------------------------------------------------------------------------------------------------------------------



| |  |  | creating uniform standards, controls (including internal control over financial reporting), procedures, policies and information systems.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------

Meeting these challenges will involve considerable risks, such as:



| |  |  | the potential disruption of each companys ongoing business and distraction of management;
| | - |  | ------------------------------------------------------------------------------------------



| |  |  | the difficulty of fully leveraging acquired technology and intellectual property rights into our products;
| | - |  | ----------------------------------------------------------------------------------------------------------



| |  |  | potential unknown liabilities associated with the merger;
| | - |  | ---------------------------------------------------------



| |  |  | unanticipated expenses related to integration, including technical and operational integration; and
| | - |  | ---------------------------------------------------------------------------------------------------



| |  |  | the impairment of relationships with employees, customers and channel partners such as Future, including potential changes in existing agreements or delay or
deferral in decisions, as a result of the integration process.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Integrating businesses and operations of this magnitude and scope can be
challenging. We may not succeed in integrating Sipexs business into ours and we may not realize the anticipated benefits of the merger. If we do not succeed in addressing these challenges or any other problems encountered in connection with
the merger, our operating results and financial condition could be adversely affected.

Our stock price is volatile.

The market price of our common stock has fluctuated significantly to date. In the future, the market price of our common stock could be subject to significant
fluctuations due to:



| |  |  | loss of or changes to key executives;
| | - |  | -------------------------------------



| |  |  | our anticipated or actual operating results;
| | - |  | --------------------------------------------



| |  |  | announcements or introductions of new products by us or our competitors;
| | - |  | ------------------------------------------------------------------------

In the past, securities and class action litigation has been brought against companies following periods of volatility in the market
prices of their securities. We may be the target of one or more of these class action suits, which could result in significant costs and divert managements attention, thereby harming our business, results of operations and financial condition.

In addition, at times the stock market has experienced extreme price and volume fluctuations that have affected the market prices of many high technology
companies, including semiconductor companies, and that have often been unrelated or disproportionate to the operating performance of those companies. Any such fluctuations may harm the market price of our common stock.

Our financial results may fluctuate significantly because of a number of factors, many of which are beyond our control.

Our financial results may fluctuate significantly. Some of the factors that affect our financial results, many of which are difficult or impossible to control or
predict, are:



| |  |  | the cyclical nature of the semiconductor industry;
| | - |  | --------------------------------------------------



| |  |  | our difficulty predicting revenues and ordering the correct mix of products from suppliers due to limited visibility provided by customers and channel partners
coupled with a high number of orders placed for products to be shipped in the same quarter;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the mix of product sales, as our margins vary across product lines;

Our expense levels are based, in part, on expectations of future revenues and are, to a large extent, fixed in the short-term. Our future revenues are difficult to predict and at times we have failed to achieve revenue expectations. We may
be unable to adjust spending in a timely manner to compensate for any unexpected revenue shortfall. If revenue levels are below expectations for any reason, operating results are likely to be materially adversely affected.

Because a significant portion of our total assets are represented by goodwill and other intangible assets which are subject to mandatory annual impairment
evaluations, we could be required to write off some or all of our goodwill and other intangible assets, which may adversely affect our financial condition and results of operations.

We accounted for our merger with Sipex using the purchase method of accounting. A portion of the purchase price for this business is allocated to identifiable tangible
and intangible assets and assumed liabilities based on estimated fair values at the date of consummation. The excess purchase price was allocated to goodwill. In accordance with the SFAS No. 142, Goodwill and Other Intangible Assets,
goodwill is not amortized but is reviewed annually or more frequently if impairment indicators arise, for impairment. We conduct our annual analysis of our goodwill in the fourth quarter of our fiscal year. Intangible assets that are subject to
amortization are reviewed for impairment in accordance with FSAS No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets, whenever events or changes in circumstances indicate that its carrying amount may not be
recoverable. When we perform future impairment tests, it is possible that the carrying value of goodwill and other intangible assets could exceed the implied fair value and therefore would require adjustment. Such adjustment would result in a charge
to operating income in that period. Once adjusted, there can be no assurance that there will not be further adjustments for impairment in future periods.

Because a significant portion of our total assets are represented by goodwill and other intangible assets, in accordance with SFAS No. 142, an annual impairment review is mandatory. Unlike other assets, goodwill cannot be defined as a
stand-alone asset and must be valued as a residual of all other assets. The assessment of goodwill impairment is a subjective process.

Estimations and assumptions regarding such as future performance and results of our operations as well as comparability of our market capitalization and its
net book value will be used. Changes in estimates and assumptions could have adverse impact on our operating result and our tax rate.

Internal
deficiencies or weaknesses in internal control over financial reporting as a result of the merger that are not yet identified could emerge, and internal control deficiencies or weaknesses previously identified by Sipex could have an adverse effect
on our financial results.

Our ability to implement our business plan successfully in an unpredictable market requires effective management systems
and a system of financial processes and controls. If we are unable to maintain an adequate level of processes and controls and in our systems and procedures, we may not be able to accurately report our financial performance on a timely basis and our
business would be adversely affected.

During the integration process, we may identify and correct deficiencies or weaknesses in our internal control and,
where and when appropriate, report on the identification and correction of these deficiencies or weaknesses. However, internal control procedures can provide only reasonable, and not absolute, assurance that deficiencies or weaknesses are
identified. Deficiencies or weaknesses that are not yet identified by us could emerge and the identification and correction of these deficiencies or weaknesses could have a material impact on our results of operations.

As part of our integration of Sipex, we are in the process of combining two previously separate internal control environments. Each control environment contains a
significant number of individual controls that were operating separately until these two environments are combined. We anticipate that the combination of the two control environments will be a complex and time-consuming process. We may make errors
or fail to properly or timely integrate all internal control elements, which could have an adverse impact on our ability to accurately produce financial statements. The disclosure of such errors or failures could have an adverse impact on our stock
price.

For the fiscal year ended January 1, 2005, Sipex management informed their Audit Committee that they identified material
weaknesses, as defined by the Public Company Accounting Oversight Board (or PCAOB), in the design and operation of Sipexs internal control over financial reporting. These weaknesses related to entity-level control activities, revenue
accounting and controls related to the financial closing process.

For the fiscal years ended December 31, 2005 and December 30, 2006, Sipex was
not an accelerated filer, and therefore Sipex was not required to make the annual report on internal control over financial reporting required by Item 308(a) of Regulation S-K. Sipexs independent registered public accounting firm was
not required to issue a separate attestation on managements assessment of Sipexs internal control over financial reporting under Item 308(b).

During fiscal year ended December 30, 2006, Sipex management continued efforts to improve its internal control over financial reporting, in particular to remediate the material weaknesses reported as of January 1, 2005. However,
as Sipex was not an accelerated filer, and therefore not subject to the requirements of Item 308(a) and Item 308(b) of Regulation S-K, as noted above, the material weaknesses reported as of January 1, 2005 had not been remediated
prior to our merger with Sipex .

We have already incurred significant costs associated with the merger and may continue to incur additional material
costs relating to the merger going forward, which may adversely affect our financial results.

We have incurred direct transaction costs associated
with the merger, including direct costs of the merger as well as liabilities accrued in connection with the merger. We may also incur charges to operations, which sometimes are not reasonably estimable, in the quarters following the consummation of
the merger in order to reflect costs associated with integration. We may incur additional material charges in subsequent quarters to reflect additional costs associated with the merger. We anticipate that the combination will require significant
cash outflows for acquisition and integration related costs. If the benefits of the merger do not exceed the integration costs, our financial results may be adversely affected.

We have made and in the future may make acquisitions and significant strategic equity investments, which may involve a number of risks. If we are unable to address these risks successfully, such acquisitions and
investments could have a materially adverse impact on our business, financial condition and results of operations.

We have undertaken a number of
strategic acquisitions and investments in the past, including our recent merger with Sipex, and may do so from time to time in the future. The risks involved with these acquisitions and investments include:

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



| |  |  | the opportunity cost associated with committing capital in such investments.

We may not be able to address these risks successfully without substantial expense, delay or other operational or financial problems. Any delays or other such operations or financial problems could adversely impact
our business, financial condition and results of operations.

We are experiencing, and may continue to experience, unforeseen complications from the
transfer of manufacturing

processes to Silan in China and Episil Technologies (Episil) in Taiwan.

Sipex transferred its manufacturing processes to foundries operated by Silan in China and Episil in Taiwan in conjunction with the closure of its Milpitas, California
wafer fabrication facility. The transfer has been and continues to be a complicated and time-consuming process that has been met with significant unforeseen complications which has delayed the transfer and is requiring additional allocation of our
resources. Additional unforeseen transferring issues may arise in the future that could cause additional delays which could materially adversely affect our ability to timely produce our products for distribution. In addition, the parties may be
unable to achieve all or any of the expected benefits of the relationship within the anticipated time-frames. The anticipated synergies between us and Silan or Episil may not be as significant as originally expected. The manufacturing processes and
wafer testing for certain products may not be qualified by us following the transfer from us to Silan or Episil, or the qualification process may take significantly longer than currently expected. This could result in additional operating costs,
loss of customers and business disruption.

If we fail to develop, introduce or enhance products that meet evolving market needs or which are
necessitated by technological advances, or we are unable to grow revenues, then our business, financial condition and results of operations could be materially and adversely impacted.

The markets for our products are characterized by:



| |  |  | changing technologies;
| | - |  | ----------------------



| |  |  | evolving and competing industry standards;
| | - |  | ------------------------------------------



| |  |  | changing customer requirements;
| | - |  | -------------------------------



| |  |  | increasing price pressure;
| | - |  | --------------------------



| |  |  | increasing product development costs;
| | - |  | -------------------------------------



| |  |  | long design-to-production cycles;
| | - |  | ---------------------------------



| |  |  | competitive solutions;
| | - |  | ----------------------



| |  |  | fluctuations in capital equipment spending levels and/or deployment;
| | - |  | --------------------------------------------------------------------



| |  |  | rapid adjustments in customer demand and inventory;
| | - |  | ---------------------------------------------------



| |  |  | increasing functional integration;
| | - |  | ----------------------------------



| |  |  | moderate to slow growth;
| | - |  | ------------------------



| |  |  | frequent product introductions and enhancements;
| | - |  | ------------------------------------------------



| |  |  | changing competitive landscape (consolidation, financial viability);
| | - |  | --------------------------------------------------------------------



| |  |  | finite market windows for product introductions; and
| | - |  | ----------------------------------------------------



| |  |  | short end market product life cycle.
| | - |  | ------------------------------------

Our growth
depends in part on our successful development and acceptance of new products for our core markets. We must: (i) anticipate customer and market requirements and changes in technology and industry standards; (ii) properly define and develop
new products on a timely basis; (iii) gain access to and use technologies in a cost-effective manner; (iv) have suppliers produce quality products; (v) continue to expand our technical and design expertise; (vi) introduce and
cost-effectively manufacture new products on a timely basis; (vii) differentiate our products from our competitors offerings; and (viii) gain customer acceptance of our products. In addition, we must continue to have our products
designed into our customers future products and maintain close working relationships with key customers to define and develop new products that meet their evolving needs. Moreover, we must respond in a rapid and cost-effective manner to shifts
in market demands, the trend towards increasing functional integration and other changes. Migration from older products to newer products may result in volatility of earnings.

Products for our customers applications are based on continually evolving industry standards and new technologies. Our ability to compete will depend in part on our ability to identify and ensure compliance with
these industry standards. The



44



---

##### Table of Contents

emergence of new standards could render our products incompatible. We could be required to invest significant time, effort and expenses to develop and
qualify new products to ensure compliance with industry standards.

The process of developing and supporting new products is complex, expensive and
uncertain, and if we fail to accurately predict and understand our customers changing needs and emerging technological trends, our business may be harmed. In addition, we may make significant investments to modify new products according to
input from one or more customers who may choose a competitors or an internal solution, or cancel the project. We may not be able to identify new product opportunities successfully, develop and bring to market new products, achieve design wins,
ensure when and which design wins actually get released to production, or respond effectively to technological changes or product announcements by our competitors. In addition, we may not be successful in developing or using new technologies or may
incorrectly anticipate market demand and develop products that achieve little or no market acceptance. Our pursuit of technological advances may require substantial time and expense and may ultimately prove unsuccessful. Failure in any of these
areas may harm our business, financial condition and results of operations.

If we are unable to convert a significant portion of our design wins
into actual revenue, our business, financial condition and results of operations could be materially and adversely impacted.

We have secured a
significant number of design wins for new and existing products. Such design wins are necessary for revenue growth. However, many of our design wins may never generate revenues if their end-customer projects are unsuccessful in the market place or
the end-customer terminates the project, which may occur for a variety of reasons. Mergers and consolidations among our customers may lead to termination of certain projects before the associated design win generates revenue. If design wins do
generate revenue, the time lag between the design win and meaningful revenue is typically between six months to greater than eighteen months. If we fail to convert a significant portion of our design wins into substantial revenue, our business,
financial condition and results of operations could be materially and adversely impacted.

If we are unable to accurately forecast demand for our
products, we may be unable to efficiently manage our inventory.

Due to the absence of substantial non-cancelable backlog, we typically plan our
production and inventory levels based on customer forecasts, internal evaluation of customer demand and current backlog, which can fluctuate substantially. As a consequence of inaccuracies inherent in forecasting, inventory imbalances periodically
occur that result in surplus amounts of some of our products and shortages of others. Such shortages can adversely affect customer relations and surpluses can result in larger-than-desired inventory levels, which can adversely affect our financial
position.

The general state of the U.S. and global economies, as well as our market, may materially and adversely affect our business, financial
condition and results of operations.

Periodic declines or fluctuations in corporate profits, lower capital equipment spending, the impact of
conflicts throughout the world, terrorist acts, natural disasters, volatile energy costs, the outbreak of communicable diseases and other geopolitical factors have had, and may continue to have, a negative impact on the U.S. and global economies.
Our revenue and profitability have generally followed market fluctuations in our industry, which fluctuations have affected the demand for our own and our customers products, thus affecting our revenues and profitability. Our customers
continue to experience consolidation in their industries which may result in project delays or cancellations. Uncertainties in anticipated spending levels or further consolidation may adversely affect our business, financial condition and results of
operations. We are unable to predict the strength or duration of current market conditions or effects of consolidation. If the market does not improve measurably, or declines, our business, financial condition and results of operations may be
materially and adversely impacted.

Our business may be adversely affected if we fail to effectively utilize and incorporate acquired technology.

We have acquired and may in the future acquire intellectual property to accelerate our time to market for new products. Acquisitions of
intellectual property may involve risks such as successful technical integration into new products, market acceptance of new products and achievement of planned return on investment. Successful technical integration in particular requires a variety
of factors which we may not currently have, such as available technical staff with sufficient time to devote to integration, the requisite skill sets to understand the acquired technology and the necessary support tools to effectively utilize the
technology. The timely and efficient integration of acquired technology may be adversely impacted by inherent design deficiencies or application requirements. The potential failure of or delay in product introduction utilizing acquired intellectual
property could lead to an impairment of capitalized intellectual property acquisition costs.

If we are unable to compete effectively with existing or new competitors, we will experience fewer customer orders,
reduced revenues, reduced gross margins and lost market share.

We compete in markets that are intensely competitive, and which are subject to both
rapid technological change and continued price erosion. Our competitors include many large domestic and foreign companies that have substantially greater financial, technical and management resources and leverage than we have.

We have experienced increased competition at the design stage, where customers evaluate alternative solutions based on a number of factors, including price, performance,
product features, technologies, and availability of long-term product supply and/or roadmap guarantee. Additionally, we experience, in some cases, severe pressure on pricing from some of our competitors or on-going cost reduction expectations from
customers. Such circumstances may make some of our products unattractive due to price or performance measures and result in losing our design opportunities or causing a decrease in our revenue and margins. Also, competition from new companies in
emerging economy countries with significantly lower costs could affect our selling price and gross margins. In addition, if competitors in Asia reduce prices on commodity products, it would adversely affect our ability to compete effectively in that
region. Specifically, we have licensed rights to Silan to market our commodity interface products that could reduce our sales in the future. Loss of competitive position could result in price reductions, fewer customer orders, reduced revenues,
reduced gross margins and loss of market share, any of which would affect our operating results and financial condition. To remain competitive, we continue to evaluate our manufacturing operations, looking for additional cost savings and
technological improvements. If we are unable to successfully implement new process technologies and to achieve volume production of new products at acceptable yields, our operating results and financial condition may be affected. Our future
competitive performance depends on a number of factors, including our ability to:



| |  |  | increase device performance and improve manufacturing yields;
| | - |  | -------------------------------------------------------------



| |  |  | accurately identify emerging technological trends and demand for product features and performance characteristics;
| | - |  | ------------------------------------------------------------------------------------------------------------------



| |  |  | develop and maintain competitive products;
| | - |  | ------------------------------------------



| |  |  | enhance our products by adding innovative features that differentiate our products from those of our competitors;
| | - |  | -----------------------------------------------------------------------------------------------------------------



| |  |  | bring products to market on a timely basis at competitive prices;
| | - |  | -----------------------------------------------------------------



| |  |  | respond effectively to new technological changes or new product announcements by others;
| | - |  | ----------------------------------------------------------------------------------------



| |  |  | adapt products and processes to technological changes;
| | - |  | ------------------------------------------------------



| |  |  | adopt or set emerging industry standards; and
| | - |  | ---------------------------------------------



| |  |  | meet changing customer requirements.
| | - |  | ------------------------------------

There can be
no assurance that our design, development and introduction schedules for new products or enhancements to our existing and future products will be met. In addition, there can be no assurance that these products or enhancements will achieve market
acceptance, or that we will be able to sell these products at prices that are favorable.

If our distributors or sales representatives stop selling
or fail to successfully promote our products, our business, financial condition and results of operations could be adversely affected.

We sell
many of our products through sales representatives and distributors, many of which sell directly to OEMs, contract manufacturers and end customers. Our non-exclusive distributors and sales representatives may carry our competitors products,
which could adversely impact or limit sales of our products. Additionally, they could reduce or discontinue sales of our products or may not devote the resources necessary to sell our products in the volumes and within the time frames that we
expect. Our agreements with distributors contain limited provisions for return of our products, including stock rotations whereby distributors may return a percentage of their purchases from us based upon a percentage of their most recent three
months of shipments. In addition, in certain circumstances upon termination of the distributor relationship, distributors may return some portion of their prior purchases. The loss of business from any of our significant distributors or the delay of
significant orders from any of them, even if only temporary, could significantly reduce our income, delay recognition of revenue and impact our ability to accurately predict cash flow.

##### Table of Contents

Moreover, we depend on the continued viability and financial resources of these distributors and sales representatives,
some of which are small organizations with limited working capital. In turn, these distributors and sales representatives are subject to general economic and semiconductor industry conditions. We believe that our success will continue to depend on
these distributors and sales representatives. If some or all of our distributors and sales representatives experience financial difficulties, or otherwise become unable or unwilling to promote and sell our products, our business, financial condition
and results of operations could be adversely affected.

We derive a substantial portion of our revenues from Future, a related party, and our
revenues would likely decline significantly if Future elected not to promote or sell our products or Future elected to, cancel, reduce or defer purchases of our products.

Future has historically accounted for a significant portion of Exars and Sipexs revenues, and it is our largest distributor worldwide. We anticipate that sales of our products to Future will continue to
account for a significant portion of our revenues. The loss of Future as a distributor, or a significant reduction in orders from Future would materially and adversely affect our operating results, business and financial condition.

We have a distributor agreement with Future that provides for Future to act as our distributor for certain products worldwide. If Future were to cease distributing these
products, we could experience a reduction in sales as we retain replacement distributors for these products. Sales to Future are made under an agreement that provides protection against price reduction for their inventory of our products. As such,
we could be exposed to significant liability if the inventory value of the products held by Future declined dramatically. Our distributor agreement with Future does not contain minimum purchase commitments. As a result, Future could cease purchasing
our products with short notice to us. In addition, Future may defer or cancel orders without penalty, which would likely cause our revenues, business and financial condition to decline.

Alonim Investments Inc., our largest stockholder, and an affiliate of Future, our largest distributor, beneficially owns approximately 16% of our common stock, which will allow Future to significantly influence
matters requiring stockholders approval. In addition, an executive officer of Future is on our board of directors, which could lead to actual or imputed influence from Future.

As a result of our merger with Sipex, an affiliate of Future, our largest distributor, owns a significant percentage of our outstanding shares and Pierre Guilbault, the
chief financial officer of Future, is a member of our board of directors. Due to its affiliates ownership of a significant percentage of our common stock, Future may be able to exert strong influence over, actions requiring the approval of our
stockholders, including the election of directors, many types of change of control transactions and amendments to our charter documents, although Future is bound by a Lock-Up and Standstill Agreement, until August 25, 2009, prohibiting Future
from either soliciting proxies or seeking to advise anyone with respect to voting our stock. The significant ownership percentage of Future could have the effect of delaying or preventing a change of control or otherwise discouraging a potential
acquirer from obtaining control of us. Conversely, by virtue of Futures percentage ownership of our stock, Future could facilitate a takeover transaction that our board of directors did not approve, although, by the terms of the same Lock-Up
and Standstill Agreement, Future is prohibited from making any public announcements with respect to, or proposing, any extraordinary transaction involving us until the first anniversary of the merger date.

This relationship could also result in actual or imputed attempts to influence management to take actions beneficial to Future which may or may not be beneficial to us
or in our best interests. Future could attempt to obtain terms and conditions more favorable than those we would typically provide our distributors because of its relationship to us. Any such actual or perceived preferential treatment could
materially and adversely affect our business, financial condition and results of operations.

We depend on third-party foundries to manufacture our
products. Any disruption in or loss of the foundries capacity to manufacture our products subjects us to a number of risks, including the potential for an inadequate supply of products and higher materials costs. These risks may lead to
delayed product delivery or increased costs, which could materially and adversely affect our business, financial condition and results of operations.

We do not own or operate a semiconductor fabrication facility or a foundry. We utilize various foundries for different processes. Our products are based on complementary metal oxide semiconductor (CMOS), Bipolar processes and Bipolar-CMOS
(BiCMOS) process. Chartered Semiconductor Manufacturing Ltd., or Chartered, located in Singapore, manufactures the majority of the CMOS wafers from which our communications and UARTs products are produced. Episil, located in Taiwan, and Silan,
located in China, manufacture the majority of wafers from which our power and serial products are produced. High Voltage BiCMOS power products are supplied by Polar Semiconductor (MN, USA) and Jazz

##### Table of Contents

Semiconductor (CA, USA). All of these foundries produce semiconductors for many other companies (many of which have greater requirements than us), and
therefore, we may not have access on a timely basis to sufficient capacity or certain process technologies. In addition, we rely on our foundries continued financial health and ability to continue to invest in smaller geometry manufacturing
processes and additional wafer processing capacity.

The manufacturing processes for our products are highly complex and are continuously being modified in
an effort to improve yields and product performance. Many of our new products are designed to take advantage of smaller geometry manufacturing processes. Due to the complexity and increased cost of migrating to smaller geometries as well as process
changes, we could experience interruptions in production or significantly reduced yields causing product introduction or delivery delays. If such delays occur, our products may have delayed market acceptance or customers may select our
competitors products during the design process. In addition, yields can be adversely affected by minute impurities in the environment or other problems that occur in the complex manufacturing process. Many of these problems are difficult to
diagnose and are time-consuming or expensive to remedy. In particular, new process technologies or new products can be subject to especially wide variations in manufacturing yields and efficiency. There can be no assurance that our foundries or the
foundries of our suppliers will not experience unfavorable yield variances or other manufacturing problems that result in delayed product introduction or delivery delays. This risk is particularly significant in the near term as we have recently
transferred certain of our manufacturing processes to Silan and Episil.

We do not have long-term wafer supply agreements with Chartered that would
guarantee wafer quantities, prices, and delivery or lead times, but we do provide minimum purchase commitments to Silan and Episil in accordance with our supply agreements. Subject to any such minimum purchase commitments, these foundries
manufacture our products on a purchase order basis. We provide Chartered and our other foundries with rolling forecasts of our production requirements. However, the ability of our foundries to provide wafers is limited by the foundries
available capacity. There can be no assurance that our third-party foundries will allocate sufficient capacity to satisfy our requirements. Furthermore, any sudden reduction or elimination of any primary source or sources of fully processed wafers
could result in a material delay in the shipment of our products. If any other delays or shortages occur in the future, our business and operating results will be negatively impacted.

In addition, we cannot be certain that we will continue to do business with our foundries on terms as favorable as our current terms. Significant risks associated with our reliance on third-party foundries include:



| |  |  | the lack of assured process technology and wafer supply;
| | - |  | --------------------------------------------------------



| |  |  | limited control over quality assurance, manufacturing yields and production costs;
| | - |  | ----------------------------------------------------------------------------------



| |  |  | financial and operating stability of the foundries;
| | - |  | ---------------------------------------------------



| |  |  | limited control over delivery schedules;
| | - |  | ----------------------------------------



| |  |  | limited manufacturing capacity of the foundries; and
| | - |  | ----------------------------------------------------



| |  |  | potential misappropriation of our intellectual property.
| | - |  | --------------------------------------------------------

We could experience a substantial delay or interruption in the shipment of our products or an increase in our costs due to any of the following:



| |  |  | a manufacturing disruption experienced by foundries utilized by us or sudden reduction or elimination of any existing source or sources of semiconductor
manufacturing materials or processes, which might include the potential closure, change of ownership, change of management or consolidation by one of our foundries;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | extended time required to identify, qualify and transfer to alternative manufacturing sources for existing or new products;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------



| |  |  | failure of our foundries to obtain raw materials and equipment;
| | - |  | ---------------------------------------------------------------



| |  |  | financial and operating stability of the foundries or any of their suppliers;
| | - |  | -----------------------------------------------------------------------------



| |  |  | acts of terrorism or civil unrest or an unanticipated disruption due to communicable diseases, political instability or natural disasters;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------

##### Table of Contents

| |  |  | a sudden, sharp increase in demand for semiconductor devices, which could strain the foundries manufacturing resources and cause delays in manufacturing and
shipment of our products; and
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | manufacturing quality control or process control issues.
| | - |  | --------------------------------------------------------

To secure foundry capacity, we may be required to enter into financial and other arrangements with foundries, which could result in the dilution of our earnings or otherwise harm our operating results.

Allocation of a foundrys manufacturing capacity may be influenced by a foundry customers size, the existence of a long-term agreement with the foundry or
other commitments. To address foundry capacity constraints, we and other semiconductor companies that rely on third-party foundries have utilized various arrangements, including equity investments in or loans to foundries in exchange for guaranteed
production capacity, joint ventures to own and operate foundries or take or pay contracts that commit a company to purchase specified quantities of wafers over extended periods. These arrangements may not be available to us on acceptable
terms, if at all. Any of these arrangements could require us to commit substantial capital and, accordingly, could require us to reduce our cash holdings, incur additional debt or secure equity financing. This could result in the dilution of our
earnings or the ownership of our stockholders or otherwise harm our operating results. Furthermore, we may not be able to obtain sufficient foundry capacity in the future pursuant to such arrangements.

If our foundries discontinue or limit the availability of the manufacturing processes needed to meet our demands or are unable to provide the technologies needed
to manufacture our products, we may face production delays or be forced to terminate affected products, which could materially and adversely impact our business, financial condition and results of operations.

Our wafer requirements represent a small portion of the total production of the foundries that manufacture our products. As a result, we are subject to the risk that a
foundry may cease production of a wafer fabrication process required by us. Additionally, we cannot be certain that our foundries will continue to devote resources to the production of our products or continue to advance the process design
technologies on which the manufacturing of our products are based. Each of these events could increase our costs and harm our ability to deliver our products on time, or force us to terminate affected products, thereby materially and adversely
affecting our business, financial condition and results of operations.

Our dependence on third-party subcontractors to assemble and test our
products subjects us to a number of risks, including the potential for an inadequate supply of products and higher materials costs. These risks may lead to delayed product delivery or increased costs, which could materially and adversely affect our
business, financial condition and results of operations.

We depend on independent subcontractors in Asia for all of the assembly and the majority
of the testing and shipping of our products to end customers. Our reliance on these subcontractors involves the following risks:



| |  |  | our reduced control over manufacturing yields, production schedules and product quality;
| | - |  | ----------------------------------------------------------------------------------------



| |  |  | the potential closure, change of ownership, change in business conditions or relationships, change of management or consolidation by one or more of our
subcontractors;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | possible unavailability of qualified assembly or test services;
| | - |  | ---------------------------------------------------------------



| |  |  | the subcontractors may cease production on a specific package type used to assemble product required by us and the possible inability to obtain an alternate source
to supply the package;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | potential increases in assembly and test costs;
| | - |  | -----------------------------------------------



| |  |  | long-term financial stability of our subcontractors and their ability to invest in new capabilities and/or expand capacity to meet increasing demand;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | disruption of services due to the outbreak of communicable diseases, acts of terrorism, natural disasters, labor disputes or civil unrest;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | disruption of manufacturing or test services due to relocation of subcontractor manufacturing facilities;

| |  |  | limited warranties from our subcontractors for products assembled and tested for us; and
| | - |  | ----------------------------------------------------------------------------------------



| |  |  | third-party subcontractors abilities to transition to smaller package types and to new package compositions.
| | - |  | -------------------------------------------------------------------------------------------------------------

These risks may lead to shipment delays and supply constraints of our products or increased cost for the finished products, either of which could adversely affect our
business, financial condition or results of operations.

Our ability to meet current demand or any increase in demand for our products may be limited
by our ability to test our semiconductor wafers.

As part of our manufacturing process, we must test many of our semiconductor wafers using certain
probe testing equipment. As such, our ability to meet current demand or any increase in demand for our products depends, in part, on our ability to purchase and install sufficient testing equipment. Obtaining and installing this
equipment is a time and capital intensive process and depends on our ability to accurately predict future sales. If we are unable to estimate future sales correctly or we are unable to obtain the necessary testing equipment on a timely basis, we may
be unable to meet the current demand or any increased demand for our products.

Our reliance on foreign suppliers exposes us to risks associated with
international operations, any of which could materially and adversely impact our business, financial condition and results of operations.

We use
semiconductor wafer foundries and assembly and test subcontractors throughout Asia to manufacture a significant portion of our products. Our dependence on these subcontractors involves the following risks:



| |  |  | disruption of services due to political, civil, labor and economic instability;
| | - |  | -------------------------------------------------------------------------------



| |  |  | disruption of services due to natural disasters or outbreak of communicable diseases;
| | - |  | -------------------------------------------------------------------------------------



| |  |  | disruption of transportation to and from Asia;
| | - |  | ----------------------------------------------



| |  |  | embargoes or other regulatory limitations affecting the availability of raw materials, equipment or changes in tax laws, tariffs, services and freight rates; and
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | compliance with local or international regulatory requirements.
| | - |  | ---------------------------------------------------------------

These risks may lead to delays in product delivery or increased costs, either of which could harm our profitability and customer relationships, thereby materially and adversely impacting our business, financial
condition and results of operations.

We depend in part on the continued service of our key engineering and management personnel and our ability to
identify, hire, incentivize and retain qualified personnel. If we lose key employees or fail to identify, hire, incentivize and retain these individuals, our business, financial condition and results of operations could be materially and adversely
impacted.

Our future success depends, in part, on the continued service of our key design engineering, technical, sales, marketing and



50

##### Table of Contents

executive personnel and our ability to identify, hire, incentivize and retain other qualified personnel.

The success of the merger will depend in part on the retention of personnel critical to the business and operations of the combined company due to, for example, their
technical skills or management expertise. Current and prospective employees may experience uncertainty about their future roles with us. Sipex, while similar to us, does not have the same corporate culture, and some former Sipex employees may not
want to work for us. In addition, competitors may recruit employees during our integration, as is common in high technology mergers. If we are unable to retain personnel that are critical to successful integration and our future operations, we could
face disruptions in operations, loss of existing customers, loss of key information, expertise or know-how, and unanticipated additional recruitment and training costs.

In the future, we may not be able to attract and retain qualified personnel, including executive officers and other key management and technical personnel necessary for the management of our business. Competition for
skilled employees having specialized technical capabilities and industry-specific expertise is intense and continues to be a considerable risk inherent in the markets in which we compete. Volatility or lack of positive performance in our stock price
and the ability to offer equity compensation to as many key employees or in amounts consistent with past practices, as a result of regulations regarding the expensing of options, may also adversely affect our ability to retain key employees, all of
whom have been granted stock options. Our employees are employed at-will, which means that they can terminate their employment at any time. The failure to retain and recruit, as necessary, key design engineers, technical, sales, marketing and
executive personnel could harm our business, financial condition and results of operations.

Our results of operations could vary as a result of the
methods, estimates and judgments we use in applying our accounting policies.

The methods, estimates and judgments we use in applying our
accounting policies have a significant impact on our results of operations. Such methods, estimates and judgments are, by their nature, subject to substantial risks, uncertainties, assumptions and changes in rulemaking by the regulatory bodies; and
factors may arise over time that lead us to change our methods, estimates, and judgments. Changes in those methods, estimates and judgments could significantly affect our results of operations. In particular, the calculation of stock-based
compensation expense under SFAS 123R, Share-Based Payment, requires us to use valuation methodologies (which were not developed for use in valuing employee stock options) and a number of assumptions, estimates, and conclusions regarding
matters such as expected forfeitures, expected volatility of our share price, the expected dividend rate with respect to our common stock, and the exercise behavior of our employees. Furthermore, there are no means, under applicable accounting
principles, to compare and adjust our expense if and when we learn about additional information that may affect the estimates that we previously made, with the exception of changes in expected forfeitures of share-based awards. Factors may arise
over time that leads us to change our estimates and assumptions with respect to future share-based compensation arrangements, resulting in variability in our share-based compensation expense over time. Changes in forecasted share-based compensation
expense could impact our gross margin percentage, research and development expense, selling, general and administrative expense and our tax rate. The change in our revenue recognition for our two primary distributors from sell-in to sell-through has
impacted our financial results as revenues and costs which had been recognized upon sell-in to these distributors are now deferred until these two distributors sell-through to their customers. The delayed in revenue recognition has unfavorably
affected our current period operating results.

Changes in our effective tax rate may have an adverse effect on our results of operations.

Our future effective tax rates may be adversely affected by a number of factors including:



| |  |  | the jurisdictions in which profits are determined to be earned and taxed;
| | - |  | -------------------------------------------------------------------------



| |  |  | the resolution of issues arising from tax audits with various tax authorities;
| | - |  | ------------------------------------------------------------------------------



| |  |  | changes in the valuation of our deferred tax assets and liabilities;
| | - |  | --------------------------------------------------------------------



| |  |  | adjustments to estimated taxes upon finalization of various tax returns;
| | - |  | ------------------------------------------------------------------------



| |  |  | increases in expenses not deductible for tax purposes, including write-offs of acquired in-process research and development and impairment of goodwill in connection
with mergers;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | changes in available tax credits;
| | - |  | ---------------------------------

| |  |  | the repatriation of non-U.S. earnings for which we have not previously provided for U.S. taxes.
| | - |  | -----------------------------------------------------------------------------------------------

Any significant increase in our future effective tax rates could adversely impact net income for future periods. In addition, the U.S. Internal Revenue Service (IRS) and
other tax authorities regularly examine our income tax returns. Our results of operations could be adversely impacted if these assessments or any other assessments resulting from the examination of our income tax returns by the IRS or other taxing
authorities are not resolved in our favor.

Our engagement with foreign customers could cause fluctuations in our operating results, which could
materially and adversely impact our business, financial condition and results of operations.

International sales have accounted for, and will
likely continue to account for a significant portion of our revenues, which subjects us to the following risks:



| |  |  | changes in regulatory requirements;
| | - |  | -----------------------------------



| |  |  | tariffs and other barriers;
| | - |  | ---------------------------



| |  |  | timing and availability of export or import licenses;
| | - |  | -----------------------------------------------------



| |  |  | disruption of services due to political, civil, labor, and economic instability;
| | - |  | --------------------------------------------------------------------------------



| |  |  | disruption of services due to natural disasters outside the United States;
| | - |  | --------------------------------------------------------------------------



| |  |  | disruptions to customer operations outside the United States due to the outbreak of communicable diseases;
| | - |  | ----------------------------------------------------------------------------------------------------------



| |  |  | difficulties in accounts receivable collections;
| | - |  | ------------------------------------------------



| |  |  | difficulties in staffing and managing foreign subsidiary and branch operations;
| | - |  | -------------------------------------------------------------------------------



| |  |  | difficulties in managing sales channel partners;
| | - |  | ------------------------------------------------



| |  |  | difficulties in obtaining governmental approvals for communications and other products;

| |  |  | limited intellectual property protection;
| | - |  | -----------------------------------------



| |  |  | foreign currency exchange fluctuations;
| | - |  | ---------------------------------------



| |  |  | the burden of complying with foreign laws and treaties; and
| | - |  | -----------------------------------------------------------



| |  |  | potentially adverse tax consequences.
| | - |  | -------------------------------------

In addition,
because sales of our products have been denominated primarily in U.S. dollars, increases in the value of the U.S. dollar as compared with local currencies could make our products more expensive to customers in the local currency of a particular
country resulting in pricing pressures on our products. Increased international activity in the future may result in foreign currency denominated sales. Furthermore, because some of our customers purchase orders and agreements are governed by
foreign laws, we may be limited in our ability, or it may be too costly for us, to enforce our rights under these agreements and to collect damages, if awarded.

The complexity of our products may lead to errors, defects and bugs, which could subject us to significant costs or damages and adversely affect market acceptance of our products.

Although we, our customers and our suppliers rigorously test our products, they may contain undetected errors, weaknesses, defects or bugs when first introduced or as
new versions are released. If any of our products contain production defects, reliability, quality or compatibility problems that are significant to our customers, our reputation may be damaged and customers may be reluctant to continue to buy our
products, which could adversely affect our ability to retain and



52



---

##### Table of Contents

attract new customers. In addition, these defects or bugs could interrupt or delay sales of affected products, which could adversely affect our results of
operations.

If defects or bugs are discovered after commencement of commercial production of a new product, we may be required to make significant
expenditures of capital and other resources to resolve the problems. This could result in significant additional development costs and the diversion of technical and other resources from our other development efforts. We could also incur significant
costs to repair or replace defective products or may agree to be liable for certain damages incurred. These costs or damages could have a material adverse effect on our financial condition and results of operations.

Because some of our integrated circuits products have lengthy sales cycles, we may experience substantial delays between incurring expenses related to product
development and the revenue derived from these products.

A portion of our revenue is derived from selling integrated circuits to communications
equipment vendors. Due to their product development cycle, we have typically experienced at least an eighteen-month time lapse between our initial contact with a customer and realizing volume shipments. We first work with customers to achieve a
design win, which may take nine months or longer. Our customers then complete their design, test and evaluation process and begin to ramp-up production, a period which typically lasts an additional nine months. The customers of communications
equipment manufacturers may also require a period of time for testing and evaluation, which may cause further delays. As a result, a significant period of time may elapse between our research and development efforts and our realization of revenue,
if any, from volume purchasing of our communications products by our customers. Due to the length of the communications equipment vendors product development cycle, the risks of project cancellation by our customers, price erosion or volume
reduction are present for an extended period of time.

Our backlog may not result in future revenue.

Due to the possibility of customer changes in delivery schedules and quantities actually purchased, cancellation of orders, distributor returns or price reductions, our
backlog at any particular date is not necessarily indicative of actual sales for any succeeding period. We may not be able to meet our expected revenue levels or results of operations if there is a reduction in our order backlog during any
particular period and we are unable to replace those sales during the same period.

Fixed operating expenses and our practice of ordering materials
in anticipation of future customer demand could make it difficult for us to respond effectively to sudden swings in demand and result in higher than expected costs and excess inventory. Such sudden swings in demand could therefore have a material
adverse impact on our business, financial condition and results of operations.

Our operating expenses are relatively fixed in the short to medium
term, and therefore, we have limited ability to reduce expenses quickly and sufficiently in response to any revenue shortfall. In addition, we typically plan our production and inventory levels based on forecasts of customer demand, which is highly
unpredictable and can fluctuate substantially. From time to time, in response to anticipated long lead times to obtain inventory and materials from our outside suppliers and foundries, we may order materials in advance of anticipated customer
demand. This advance ordering may result in excess inventory levels or unanticipated inventory write-downs if expected orders fail to materialize. This incremental cost could have a materially adverse impact on our business, financial condition and
results of operations.

We may be unable to protect our intellectual property rights, which could harm our competitive position.

Our ability to compete is affected by our ability to protect our intellectual property rights. We rely on a combination of patents, trademarks, copyrights, mask work
registrations, trade secrets, confidentiality procedures and non-disclosure and licensing arrangements to protect our intellectual property rights. Despite these efforts, we may be unable to protect our proprietary information. Such intellectual
property rights may not be recognized or if recognized, it may not be commercially feasible to enforce. Moreover, we cannot be certain that our competitors will not independently develop technology that is substantially similar or superior to our
technology.

More specifically, our pending patent applications or any future applications may not be approved, and any issued patents may not provide us
with competitive advantages or may be challenged by third parties. If challenged, our patents may be found to be invalid or unenforceable, and the patents of others may have an adverse effect on our ability to do business. Furthermore, others may
independently develop similar products or processes, duplicate our products or processes or design around any patents that may be issued to us.

We
could be required to pay substantial damages or could be subject to various equitable remedies if it were proven that



53



---

##### Table of Contents

we infringed the intellectual property rights of others.

As a general matter, the semiconductor industry is characterized by substantial litigation regarding patents and other intellectual property rights. If a third party were to prove that our technology infringed its intellectual property
rights, we could be required to pay substantial damages for past infringement and could be required to pay license fees or royalties on future sales of our products. If we were required to pay such license fees whenever we sold our products, such
fees could exceed our revenue. In addition, if it were proven that we willfully infringed a third partys proprietary rights, we could be held liable for three times the amount of the damages that we would otherwise have to pay. Such
intellectual property litigation could also require us to:



| |  |  | stop selling, incorporating or using our products that use the infringed intellectual property;
| | - |  | -----------------------------------------------------------------------------------------------



| |  |  | obtain a license to make, sell or use the relevant technology from the owner of the infringed intellectual property, which license may not be available on
commercially reasonable terms, if at all; and/or
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | redesign our products so as not to use the infringed intellectual property, which may not be technically or commercially feasible.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------

The defense of infringement claims and lawsuits, regardless of their outcome, would likely be expensive and could require a significant portion of managements
time. In addition, rather than litigating an infringement matter, we may determine that it is in our best interests to settle the matter. Terms of a settlement may include the payment of damages and our agreement to license technology in exchange
for a license fee and ongoing royalties. These fees could be substantial. If we were required to pay damages or otherwise became subject to such equitable remedies, our business, financial condition and results of operations would suffer. Similarly,
if we were required to pay license fees to third parties based on a successful infringement claim brought against us, such fees could exceed our revenue.

Occasionally, we enter into agreements that expose us to potential damages that exceed the value of the agreement.

We have given
certain customers increased indemnification for product deficiencies that is in excess of the standard limited warranty indemnification and could possibly result in greater costs, in excess of the original contract value. In an attempt to limit this
liability, we have also increased our errors and omissions insurance policy to partially offset these potential additional costs; however, our insurance coverage could be insufficient to prevent us from suffering material losses if the
indemnification amounts are large enough.

Earthquakes and other natural disasters may damage our facilities or those of our suppliers and customers.

Our corporate headquarters in Fremont, California is located near major earthquake faults that have experienced seismic activity. In addition,
some of our customers and suppliers are in locations which may be subject to similar natural disasters. In the event of a major earthquake or other natural disaster near our headquarters, our operations could be disrupted. Similarly, a major
earthquake or other natural disaster affecting one or more of our major customers or suppliers could adversely impact the operations of those affected, which could disrupt the supply of our products and harm our business.
