PMC-Sierra, Inc.

NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)

NOTE 1. Summary of Significant Accounting Policies

Description of business. PMC-Sierra, Inc. (the Company or PMC) designs, develops, markets and supports high-speed broadband communications semiconductors, storage semiconductors and microprocessor-based
System-on-Chips (SOCs) for metro, access, fiber-to-the-home, wireless infrastructure, storage, laser printers and customer premise equipment. The Company offers worldwide technical and sales support through a network of offices in North
America, Europe and Asia.

Basis of presentation. The accompanying condensed consolidated financial statements have been prepared pursuant to the
rules and regulations of the United States Securities and Exchange Commission (SEC) and United States Generally Accepted Accounting Principles (GAAP). Certain information and footnote disclosures normally included in annual
financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to those rules or regulations. These interim financial statements are unaudited, but reflect all adjustments that are, in the opinion of management,
necessary to provide a fair statement of results for the interim periods presented. These financial statements should be read in conjunction with the audited consolidated financial statements and accompanying notes in the Companys Annual
Report on Form 10-K for the year ended December 30, 2007. The results of operations for the interim periods are not necessarily indicative of results to be expected in future periods. Fiscal 2008 will consist of 52 weeks and will end on Sunday,
December 28. Fiscal 2007 consisted of 52 weeks and ended on Sunday, December 30. The first six months of 2008 and 2007 consisted of 26 weeks.

Estimates.The preparation of financial statements and related disclosures in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial
statements and the accompanying notes. Estimates are used for, but not limited to, stock-based compensation, purchase accounting assumptions including those used to calculate the fair value of intangible assets and goodwill, the accounting for
doubtful accounts, inventory reserves, depreciation and amortization, asset impairments, sales returns, warranty costs, income taxes, including uncertain tax positions, restructuring costs and contingencies. Actual results could differ materially
from these estimates.

Cash and cash equivalents.At June 29, 2008, cash and cash equivalents included $0.8 million (December 30,
2007$0.8 million) pledged with a bank as collateral for letters of credit issued as security for leased facilities.

Inventories. Inventories are stated at the lower of cost (first-in, first out) or market (estimated net realizable
value). Inventories (net of reserves of $10.2 million and $9.8 million at June 29, 2008 and December 30, 2007, respectively) were as follows:



|                 |  |          |        |              |   |

Derivatives and Hedging Activities.Fluctuating foreign exchange rates may negatively impact PMCs
operations and cash flows. The Company periodically hedges foreign currency forecasted transactions related to certain operating expenses. All derivatives are recorded in the balance sheet at fair value. For a derivative designated as a fair value
hedge, changes in the fair value of the derivative and of the hedged item attributable to the hedged risk are recognized in net income (loss). For a derivative designated as a cash flow hedge, the effective portions of changes in the fair value of
the derivative are recorded in other comprehensive income (loss) and are recognized in net income (loss) when the hedged item affects net income (loss). Ineffective portions of changes in the fair value of cash flow hedges are recognized in net
income (loss). If the derivative used in an economic hedging relationship is not designated in an accounting hedging relationship or if it becomes ineffective, changes in the fair value of the derivative are recognized in net income (loss). During
the quarter ended June 29, 2008, all hedges were designated as cash flow hedges.

Product warranties. The Company provides a limited warranty
on most of its standard products and accrues for the estimated cost at the time of shipment. The Company estimates its warranty costs based on historical failure rates and related repair or replacement costs. The change in the Companys accrued
warranty obligations from December 30, 2007 to June 29, 2008 and for the same period in the prior year were as follows:



|                                                               |  |                  |       |   |         |   |       |

The Companys accrual for warranty obligations is included in accrued liabilities in the condensed
consolidated balance sheet.

Other Indemnifications.From time to time, on a limited basis, the Company indemnifies its customers, as well as
its suppliers, contractors, lessors, and others with whom it enters into contracts, against combinations of loss, expense, or liability arising from various triggering events related to the sale and use of its products, the use of their goods and
services, the use of facilities, the state of assets that the Company sells and other matters covered by such contracts, normally up to a specified maximum amount. The Company evaluates estimated losses for such indemnifications under Statement of
Financial Accounting Standards (SFAS) No. 5, Accounting for Contingencies, as interpreted by the Financial Accounting Standards Board (FASB) Interpretation No. 45, Guarantors Accounting and
Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others. The Company has no history of significant indemnification claims for such obligations.

Stock-based compensation.The Company accounts for its compensation expense for all share-based payment awards in accordance with SFAS No. 123 (revised
2004), Share-Based Payment (SFAS 123(R)). SFAS 123(R) requires the Company to measure the cost of services received in exchange for an award of equity instruments based on the grant-date fair value of the award. The cost of
such award will be recognized over the period during which services are provided in exchange for the award, generally the vesting period.

During the three
and six months ended June 29, 2008, the Company recognized $7.4 million and $14.4 million in stock-based compensation expense, respectively. Where a tax deduction for stock-based compensation was available to the Company, a valuation allowance
for the related deferred tax assets was recorded.

The Company uses the straight-line method over the requisite service period for attributing stock-based
compensation expense. See Note 4 to the condensed consolidated financial statements for further information on stock-based compensation.

Recent Accounting
Pronouncements.

In December 2007, the FASB issued SFAS No. 141 (revised 2007), Business Combinations(SFAS 141(R)). SFAS 141(R) will change the accounting for acquisitions that close beginning in 2009. More transactions and events will qualify as business combinations and will be accounted for at fair value under the new
standard. SFAS 141(R) promotes greater use of fair values in financial reporting. Some of the changes will introduce more volatility into earnings. SFAS 141(R) is effective for fiscal years beginning on or after December 15, 2008. The
Company is currently assessing the potential impact that SFAS 141(R) may have on its results of operations, financial position and cash flows.

In
December 2007, the FASB issued SFAS No. 160, Noncontrolling Interests in Consolidated Financial Statements (SFAS 160), an amendment of Accounting Research Bulletin (ARB) No. 51. SFAS 160
will change the accounting and reporting for minority interests which will be recharacterized as noncontrolling interests and classified as a component of equity. SFAS 160 is effective for fiscal years beginning on or after December 15,
2008. SFAS 160 requires retroactive adoption of the presentation and disclosure requirements for existing minority interests. The Company does not expect that SFAS 160 will have a material impact on its financial statement disclosure.

In December 2007, the FASB issued EITF Issue 07-1, Accounting for Collaborative Arrangements (EITF
07-1). Collaborative arrangements are agreements between parties to participate in some type of joint operating activity. The task force provided indicators to help identify collaborative arrangements and provides for reporting of such
arrangements on a gross or net basis pursuant to guidance in existing authoritative literature. The task force also expanded disclosure requirements about collaborative arrangements. Conclusions within EITF 07-1 are to be applied retrospectively.
The Company is currently assessing the impact that EITF 07-1 may have on its financial position, results of operations and cash flows.

In September 2006,
the FASB issued SFAS No.157, Fair Value Measurements (SFAS 157), which defines fair value, establishes a framework for measuring fair value in accordance with generally accepted accounting principles, and expands
disclosures about fair value measurements. SFAS 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007. In February 2008, the FASB issued FSP 157-2, Effective Date of FASB Statement
No. 157, which delays the effective date of SFAS 157 for non-financial assets and liabilities to fiscal years beginning after November 15, 2008. The adoption of SFAS 157 related to financial assets and liabilities did not
have a material impact on our consolidated financial statements. The Company is currently evaluating the impact, if any, that SFAS 157 may have on its future consolidated financial statements related to non-financial assets and liabilities.

In May 2008, the FASB issued Staff Position No. Accounting Principles Board Opinion 14-1, Accounting for Convertible Debt Instruments That May
Be Settled in Cash Upon Conversion (Including Partial Cash Settlements) (APB 14-1), which will change the accounting treatment for convertible securities which the issuer may settle fully or partially in cash. Under APB 14-1, cash
settled convertible securities will be separated into their debt and equity components. The value assigned to the debt component will be the estimated fair value, as of the issuance date, of a similar debt instrument without the conversion feature,
and the difference between the proceeds for the convertible debt and the amount reflected as a debt liability will be recorded as additional paid in capital. As a result, the debt will be recorded at a discount reflecting its below market coupon
interest rate. The debt will subsequently be accreted to its par value over its expected life, with the rate of interest that reflects the market rate at issuance being reflected on the statements of operations. This change in methodology will
affect the calculations of net income (loss) and earnings (loss) per share for many issuers of cash settled convertible securities. APB 14-1 will become effective for our fiscal year beginning in 2010. The Company is currently evaluating the impact
of the adoption of APB 14-1 on its consolidated financial statements.

In March 2008, the FASB issued SFAS No. 161, Disclosures about
Derivative Instruments and Hedging Activities(SFAS 161), which is intended to improve financial reporting about derivative instruments and hedging activities by requiring enhanced disclosures about the effects of an
entitys derivative instruments and hedging activities on its results of operations, financial position, and cash flows. SFAS 161 is effective for financial statements issued for fiscal years and interim periods beginning after
November 15, 2008, with early application encouraged. The Company is currently assessing the potential impact that SFAS 161 may have on its financial statements.

NOTE 2. Derivative Instruments and Hedging Activities

PMC generates revenues in U.S. dollars but incurs a portion of its operating expenses in various foreign currencies. To minimize the short-term impact of foreign currency fluctuations, the Company uses currency
forward contracts.

At June 29, 2008, the Company had six contracts outstanding to purchase Canadian dollars, all with maturities of less than twelve
months, which qualified and were designated as cash flow hedges. The U.S. dollar notional amount of these contracts was $29.6 million and the contracts had a fair value of $(1.0) million as of June 29, 2008. There was no gain or loss from the
ineffective portion of the hedges.

NOTE 3. Fair Value Measurements

On January 1, 2008, the Company adopted SFAS No. 157, Fair Value Measurements (SFAS 157), which defines fair value, establishes guidelines for measuring fair value and expands disclosures on fair value
measurements. SFAS 157 defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction
between market participants on the measurement date. SFAS 157 also specifies a hierarchy of valuation techniques which requires an entity to maximize the use of observable inputs that may be used to measure fair value:

Level 1  Quoted prices in active markets are available for identical assets and liabilities. The Companys Level 1 assets include cash equivalents, which are
generally acquired or sold at par value and are actively traded.

Level 2  Observable inputs other than Level 1 prices, such as quoted prices for
similar assets or liabilities; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. The Companys Level 2 liabilities include forward currency
contracts whose value is determined using a pricing model with inputs that are observable in the market or corroborated with observable market data.

Level
3  Pricing inputs include significant inputs that are generally not observable in the marketplace. These inputs may be used with internally developed methodologies that result in managements best estimate of fair value. At each balance
sheet date, the Company performs an analysis of all instruments subject to SFAS 157 and would include in Level 3 all of those whose fair value is based on significant unobservable inputs.

The Company received cash of $4.2 million and $8.1 million on the issuance of stock-based awards during the three
and six months ended June 29, 2008, respectively.

Equity Award Plans

The Company issues its common stock under the provisions of various stock award plans. Stock option awards are granted with an exercise price equal to the closing market price of the Companys common stock at the
grant date. The options generally expire within five to ten years and vest over four years.

In 2001, the Company simplified its plan structure. The 2001 Stock Option Plan (2001 Plan) was created to
replace a number of stock option plans the Company had assumed in connection with mergers and acquisitions completed prior to 2001. The number of shares available for issuance under the 1994 Incentive Stock Plan (1994 Plan) was approved
by stockholders. New stock options or other equity incentives may only be issued under the 1994 Plan and the 2001 Plan. In 2006, the Company assumed the stock option plans and all outstanding stock options of Passave, Inc. as part of the merger
consideration in that business combination.

Activity under the option plans during the six months ended June 29, 2008 was as follows:

No adjustment was required with respect to fully vested
options that expired during the three and six months ended June 29, 2008. An adjustment of $2.8 million and $4.7 million was recorded for pre-vesting forfeitures associated primarily with restructuring related activities carried out in 2007,
during the three and six months ended June 29, 2008, respectively.

The fair value of the Companys stock option awards granted to employees during the six months ended June 29, 2008, was estimated using a lattice-binomial valuation model. The binomial model considers the
contractual term of the option, the probability that the option will be exercised prior to the end of its contractual life, and the probability of termination or retirement of the option holder in computing the value of the option. The model
requires the input of highly subjective assumptions including the expected stock price volatility and expected life.

The Companys estimates of
expected volatilities are based on a weighted historical and market-based implied volatilities. The Company uses historical data to estimate option exercises and employee terminations within the valuation model; separate groups of employees that
have similar historical exercise behavior are considered separately for valuation purposes. The expected term of options granted is derived from the output of the stock option valuation model and represents the period of time that granted options
are expected to be outstanding. The risk-free rate for periods within the contractual life of the stock option is based on the U.S. Treasury yield curve in effect at the time of the grant.

The fair values of the Companys stock option awards were calculated for expense recognition in the three and six
months ended June 29, 2008 and in the three and six months ended July 1, 2007, using an estimated forfeiture rate, assuming no expected dividends and using the following weighted average assumptions:

The weighted average grant-date fair value per stock option granted during the three and six months ended
June 29, 2008, was $4.24 and $2.88 respectively, per stock option. The total intrinsic value of stock options exercised during the three and six months ended June 29, 2008 was $3.2 million and $4.0 million, respectively.

As of June 29, 2008, there was $36.4 million of total unrecognized compensation cost related to nonvested stock-based compensation arrangements granted under the
plans, which is expected to be recognized over an average period of 2.7 years.

Restricted Stock Units

On February 1, 2007, the Company amended its stock award plans to allow for the issuance of Restricted Stock Units (RSUs) to employees and members of the
Board of Directors. The first grant of RSUs occurred on May 25, 2007. The grants vest over varying terms, to a maximum of four years from the date of grant.

A summary of RSU activity during the six months ended June 29, 2008 is as follows:



|                                                                 |  |                       |   |  |                                           |  |

Employee Stock Purchase Plan

In 1991, the Company adopted an Employee Stock Purchase Plan (ESPP) under Section 423 of the Internal Revenue Code. The ESPP allows eligible participants to purchase shares of the Companys common stock through payroll
deductions at a price of 85% of the lower of the fair market value of the Companys stock on the close of the first trading day or last trading day of the six-month purchase period. Under the ESPP, the number of shares authorized to be
available for issuance under the plan is increased automatically on January 1 of each year until the expiration of the plan. The increase will be limited to the lesser of (i) 1% of the outstanding shares on January 1 of each year,
(ii) 2,000,000 shares (after adjusting for stock dividends), or (iii) an amount to be determined by the Board of Directors.

During the first
quarter of 2008, 897,883 shares were issued under the ESPP at a weighted-average price of $3.91 per share. No ESPP awards were granted during the three months ended June 29, 2008. As of June 29, 2008, 7,252,057 shares were available for
future issuance under the ESPP (December 30, 2007  8,149,940).

The weighted average grant-date fair value of ESPP awards granted during the three
months ended March 30, 2008 was $0.45.

As of June 29, 2008, total unrecognized compensation costs, adjusted for estimated forfeitures, related
to non-vested ESPP awards was $2.0, which is expected to be recognized over the next 1.6 years.

2007

In the first
quarter of 2007, the Company initiated a cost-reduction plan that involved staff reductions of 175 employees at various sites and the closure of design centers in Saskatoon, Saskatchewan and Winnipeg, Manitoba. The Company also vacated excess office
space at its Santa Clara, California facility. PMC continued to rationalize costs in the fourth quarter of 2007 by reducing headcount by 18 employees primarily at the Burnaby, British Columbia facility.

To date, the Company has incurred $10.5 million in termination and relocation costs, $3.0 million for excess facilities and $2.5 million in asset impairment charges.

The Company has made payments of $11.5 million in connection with this plan. As of June 29, 2008, $0.4 million in severance costs remained to be paid
and payments related to the excess facilities may extend until 2011.

2006

In the third quarter of 2006, the Company closed its Ottawa, Ontario development site in order to reduce operating expenses and the space was vacated by the end of the fourth quarter of 2006. Approximately 35
positions were eliminated, primarily from research and development, resulting in the Company recording restructuring charges for termination benefits, relocation costs and accrual for excess facilities. The Company also eliminated 10 positions from
research and development in its Portland, Oregon development site, resulting in restructuring charges for severance, excess facilities, contract termination costs and asset impairment.

##### Table of Contents

In connection with these two actions, the Company has recorded $2.5 million related to excess facilities and contract
termination costs, $3.0 million in severance costs and $0.2 million in asset impairment charges, to date. In 2007, the Company reduced its estimated severance accrual by $0.3 million and its accrual for excess facilities by $0.4 million, as the
Company fulfilled a portion of these obligations. The Company has made payments of $4.1 million related to the 2006 plan. As of June 29, 2008, all severance costs have been paid and payments related to the excess facilities will extend to 2010.

2005

During 2005, the Company completed various
restructuring activities aimed at streamlining production and reducing operating expenses. In the first quarter of 2005, the Company terminated 24 employees across all business functions. In the second quarter of 2005, the Company expanded the
workforce reduction activities initiated during the first quarter and terminated 63 employees from research and development located in the Santa Clara facility. In addition, the Company consolidated two manufacturing facilities (Santa Clara and
Burnaby) into one facility (Burnaby), which involved the termination of 26 employees from production control, quality assurance, and product engineering. In the third quarter, the Company consolidated its facilities and vacated excess space in its
Santa Clara location.

In the first quarter of 2006, the Company continued the workforce reduction plans initiated in 2005, primarily from its research and
development group, in the Santa Clara facility.

To date, the Company has recorded $6.3 million for excess facilities and contract termination costs, $9.2
million for termination benefits and $0.9 million write-down of equipment and software assets whose assets were impaired as a result of this plan. In 2006, the Company reduced its accrual for termination benefits by $0.4 million as a portion of the
Companys obligation was fulfilled.

As of June 29, 2008, the Company has made payments relating to these activities of $12.7 million and all
severance costs have been paid out. Payments related to the excess facilities will extend to 2011.

2003 and 2001

In 2003 and 2001, the Company implemented three restructuring plans aimed at focusing development efforts on key projects and reducing operating costs in response to the
severe and prolonged economic downturn in the semiconductor industry. The Companys assessment of the market demand for its products, and the development efforts necessary to meet this demand, were key factors in the decisions to implement
these restructuring plans. Cost reductions in all other functional areas were also implemented, as fewer resources were required to support the reduced level of development and sales activities during these periods.

##### Table of Contents

The January 2003 restructuring included the termination of 175 employees and the closure of design centers in Maryland,
Ireland and India, and vacating office space in the Santa Clara facility. To date, the Company has recorded restructuring charges of $18.3 million in accordance with SFAS No. 146, Accounting for Costs Associated with Exit or Disposal
Activities including $1.5 million for asset write-downs. These charges related to workforce reduction, lease and contract settlement costs and the write-down of certain property, equipment and software assets whose value was impaired as a
result of this restructuring plan. The Company has disposed of the property improvements and computer equipment and software licenses have been cancelled or are no longer being used. In 2006, the Company reversed $2.3 million of this restructuring
accrual because certain floors in the Santa Clara facility that had been vacated in 2003 were re-occupied in 2006 due to the addition of personnel that occurred with the acquisition of the Storage Semiconductor Business. The Company reversed an
additional $0.5 million in 2007, as it completed a portion of the lease obligation at this site.

The October 2001 restructuring plan included the
termination of 341 employees, the consolidation of excess facilities and the curtailment of certain research and development projects, resulting in a restructuring charge of $175.3 million, including $12.2 million of asset write-downs. Due to the
continued downturn in real estate markets, the Company recorded additional provisions for abandoned office facilities of $1.3 million in the fourth quarter of 2004.

In the first quarter of 2001, the Company recorded a charge of $19.9 million for a restructuring plan that included the termination of 223 employees across all business functions, the consolidation of a number of
facilities and the curtailment of certain research and development projects. Due to the continued downturn in real estate markets, the Company has recorded additional provisions for abandoned office facilities totaling $3.9 million since 2004.

To date, the Company has made cash payments of $13.3 million and $178.1 million related to the 2003 and 2001 plans,
respectively. The Company has completed the activities contemplated in these restructuring plans, but has not yet terminated the leases on all of its surplus facilities. Efforts to exit these sites are ongoing, but the payments related to these
facilities could extend to 2011.

NOTE 6. Investments in debt securities

At June 29, 2008, the Company did not hold any investments in direct debt securities (December 31, 2007$35.1 million). The investments held in 2007 were comprised of corporate bonds and notes. These
securities were classified as available-for-sales investments and had a maturity of three months or less. These investments are included in cash and cash equivalents in the condensed consolidated balance sheet.

NOTE 7. Long-term obligations

On October 26, 2005, the Company issued
$225.0 million aggregate principal amount of 2.25% senior convertible notes that are due on October 15, 2025. The Company has recorded these notes as long-term debt and issuance costs of $6.8 million were deferred and are being amortized over
seven years, which is the Companys earliest call date. This approximates the effective interest method.

During the first quarter of 2008, the
Company repurchased $98.0 million principal amount of these notes for a total of $94.5 million and expensed $2.2 million of related unamortized debt issue costs and transaction costs, resulting in a net gain of $1.3 million. The Company also paid
$0.8 million of accrued interest as of the repurchase dates. At June 29, 2008, $127.0 million of these notes remained outstanding and $2.4 million of unamortized debt issue costs were included in investments and other assets.

NOTE 8. Income Taxes

The Company recorded a tax recovery of $120.4 million
and $81.7 million for the three and six months ended June 29, 2008, respectively, and a $3.2 million tax provision and a $2.3 million tax recovery for the three and six months ended July 1, 2007, respectively.

The tax recovery recognized in the first half of 2008 is primarily attributable to two factors. During the first quarter of 2008, one of the Companys foreign
subsidiaries received a written communication from a tax authority pertaining to its 2000 tax year, resulting in an additional accrual of $26.5 million, including interest, as part of its liability for unrecognized tax benefits. In the second
quarter of 2008, one of the Companys foreign subsidiaries settled several ongoing tax matters for less than had been accrued as part of its liability for unrecognized tax benefits, resulting in the recognition of tax benefits of $124.1 million
that were previously included in the liability for unrecognized tax benefits. As a result of this settlement, the Company agreed to pay $18.0 million in cash and utilize $31.6 million in net investment tax credits.

##### Table of Contents

As at June 29 2008, our liability for unrecognized tax benefits on a world-wide consolidated basis was $33.0
million. Recognition of an amount different from this estimate would affect the Companys effective tax rate.

The Company and its subsidiaries file
income tax returns in the U.S. in various states, local and foreign jurisdictions. The preceding three tax years generally remain subject to examination by federal and most state tax authorities. In significant foreign jurisdictions, the preceding
seven tax years generally remain subject to examination by their respective tax authorities.

|(1) | PMC-Sierra, Ltd. special shares are included in the calculation of basic weighted average common shares outstanding.
|--- | --------------------------------------------------------------------------------------------------------------------

Since PMC-Sierra had a net loss for the three and six months ended July 1, 2007, there is no difference between basic and diluted net loss per share. If the Company
had recorded net income for the three and six months ended July 1, 2007, it would have included in the computed dilutive potential common shares, common stock equivalents totaling approximately 2.4 million and 1.9 million,
respectively, relating to stock options, employee stock purchase plan, and restricted stock units. Common stock equivalents related to the 2.25% senior convertible notes were excluded from the diluted net income (loss) per share calculation for
all periods presented because they would have been anti-dilutive.

Note 11. Contingencies

Stockholder Derivative Lawsuits

Three derivative actions have been filed against the Company, as a nominal
defendant, and various current and former officers and/or directors: (1) Meissner v. Bailey, et al., Santa Clara Superior Court Case No. 1-06-CV-071329 (filed September 18, 2006); (2) Beiser v. Bailey, et
al., United States District Court for the Northern District of California Case No. 5:06-CV-05330-RS (filed August 29, 2006); and (3) Barone v. Bailey, et al., United States District Court for the Northern District of
California (the Federal Court) Case No. 4:06-CV-06473-SBA (filed October 16, 2006). On November 21, 2006, the Beiser and Barone actions were consolidated into one case. On January 18, 2007, the Santa Clara
County Superior Court in California ordered that the Meissner action be stayed pending the outcome of the consolidated, federal Beiser/Barone action.

##### Table of Contents

The Beiser/Barone plaintiffs generally allege that various current and former Company directors and/or officers breached
their duty of loyalty and/or duty of care to the Company and its stockholders and that these purported breaches of fiduciary duties caused harm to the Company. The plaintiffs seek to recover damages on behalf of the Company. They also allege
violations of federal securities laws. The Company is a nominal defendant, but any recovery in the litigation would be paid to the Company, rather than to its stockholders. The defendants have entered into joint defense arrangements.

The defendants moved to dismiss the Beiser/Barone action on various legal grounds including that the plaintiffs failed to state a claim and failed to
plead with particularity facts establishing that a litigation demand on the board of directors of the Company would have been futile at the time they commenced the derivative lawsuit. The Federal Court dismissed the consolidated
complaint on August 22, 2007 and gave plaintiffs leave to amend. The Federal Court dismissed the plaintiffs first amended consolidated complaint on May 8, 2008 and permitted plaintiffs leave to amend one last time.
Defendants moved to dismiss the second amended complaint which motions will be heard on August 20, 2008.

On July 18, 2008, Ian Beiser, a named
plaintiff in the Beiser/Barone action, filed a complaint in the Delaware Court of Chancery compelling the Company to permit plaintiff to inspect and make copies of the Companys books and records. The Company intends to move to dismiss
Beisers complaint on or before August 7, 2008. Beiser/Barone had previously filed a motion to compel production of the Companys books and records in the Federal Court, which motion was denied on May 8, 2008.

As at June 29, 2008, the Company has not accrued costs for potential losses related to the Beiser/Barone action.

OVERVIEW

We generate
revenues from the sale of semiconductor devices that we have designed and developed or acquired. Almost all of our revenues in any given year come from the sale of semiconductors that are developed prior to that year. For example, 99% of our
revenues in the first six months of 2008 came from parts developed or acquired in 2007 and earlier. After an individual product is released for production and announced it may take several years before that product generates any significant
revenues.

Our current revenues are generated by a portfolio of more than 350 products. Our diverse product portfolio services a number of key end markets:
the access area of the wide area network, where data traffic flows between homes and business to central offices of service providers; the metropolitan area of the network where high-speed communication and data transfer occurs between cities or
regional areas; enterprise storage, where institutions and businesses store and access their data or enterprise networking equipment and data management such as routers, switches, and laser printers.

We expend a substantial amount every year for the research and development of new semiconductor devices. We determine the amount to invest in the development of new
semiconductors based on our assessment of the future market opportunities for those components, and the estimated return on investment. To compete globally we must invest in businesses and technologies that are both growing in demand and are cost
competitive in the geographic markets that we serve. Going forward, we plan to continue to focus on finding innovative solutions to our customers problems while finding further operational efficiencies.

Results of Operations

Second Quarter of 2008 and 2007

Net revenues for the second quarter of 2008 were $139.8 million compared to $104.7 million for the same period in
2007, an increase of $35.1 million, or 34%. Sales of our access-related products increased by 120% compared to the second quarter of 2007. This increase is primarily attributable to the growth in sales of our fiber-to-the-home products in Asia.
Revenues generated from our enterprise markets, which are served by our storage and the microprocessor-based SOC products increased by 28% compared to the second quarter of 2007. This increase was primarily due to our storage devices in 4G Fibre
Channel and 3G SAS interconnect going into production in 2008. Sales to the communications markets, which are served by our wide area network (WAN) infrastructure and wireless products increased by 11% from the second quarter of 2007.

##### Table of Contents

The growth in our fiber-to-the-home sales was driven by an increase in shipments on a year-over-year basis as our Chinese
customers delivered passive optical (EPON) devices to product field trials to the China market. In addition, shipments to Japan and Korea increased as carriers build out their networks. The growth in our enterprise storage sales was
attributable to an increase in storage capacity upgrades and information management solutions expenditures in the second quarter of 2008. The sales of microprocessor-based SOC products increased this past quarter primarily due to increased activity
in the laser printer market. Revenues from our WAN infrastructure products increased in the second quarter of 2008, compared to the same quarter in 2007. The increase was primarily attributable to changes in circumstances in how we conduct business
with one of the international entities of a certain distributor to a sell-through basis, which is consistent with our revenue recognition practice for business conducted in North America with that distributor.

Total gross profit increased $23.8 million in the second quarter of 2008 compared to the same period in 2007.
Gross profit as a percentage of revenues was 65% in the second quarter of 2008 compared with 64% in the second quarter of 2007.

While product mix can
influence our gross profit as a percentage of revenue from quarter to quarter, our underlying gross profit percentage in the second quarter of 2008 remained consistent with that in the second quarter of 2007 as average selling prices decreased in
approximately the same proportion as decreases in manufacturing costs.

Research and Development and Selling, General and Administrative Expenses

Our research and development, or R&D, expenses decreased $1.6 million or 4% in the second quarter of 2008 compared to the second quarter of 2007. This year over year
decrease is primarily attributable to $1.1 million of lower materials costs due to reduction in photomasks and wafer expenses, and payroll-related savings of $1.3 million mainly resulting from our restructuring activities in the first quarter of
2007, partially offset by $0.8 million increase in infrastructure related expenditures for normal maintenance of equipment.

Our selling, general and
administrative, or SG&A, expenses decreased by $1.0 million, or 4%, in the second quarter of 2008 compared to the second quarter of 2007. This decrease is primarily attributable to the restructuring activities undertaken in the second quarter of
2007. As a result of those activities, payroll-related costs and facilities-related costs were $1.4 million and $0.7 million lower, respectively. Professional fees were $1.2 million lower in the second quarter of 2008 compared to the second quarter
of 2007 mainly due to settlement of a litigation matter in August 2007. Other SG&A costs were $2.3 million higher in the second quarter of 2008 compared to the second quarter of 2007. The primary reason for the increase is that in the second
quarter of 2007, the Company received a credit of $2.2 million arising from the favorable settlement of a payroll tax matter with the United Kingdom tax authorities.

Amortization of purchased intangible assets and in-process research and development

In the first and second quarters
of 2006, we completed the acquisitions of the Storage Semiconductor Business from Avago, and of Passave, Inc., respectively. Amortization of intangible assets acquired from the Storage Semiconductor Business and Passave in the second quarter of 2008
was $4.7 million and $5.1 million, respectively (amortization from the Storage Semiconductor Business and Passave in the second quarter of 2007 was $4.7 million and $5.1 million, respectively).

Foreign exchange loss

We have significant design presence outside the United States. The majority of our operating expense exposures to changes in the value of the Canadian Dollar relative to the United States Dollar have been hedged through the fourth quarter
of 2008.

Our net foreign exchange loss was $1.1 million in the second quarter of 2008, which was primarily due to a $0.8 million foreign exchange loss on
the revaluation of our net tax liability in a foreign jurisdiction. The revaluation of this foreign tax liability was required because of depreciation of other currencies against the United States Dollar. The foreign exchange rate between the US
dollar and the currencies of countries where we have significant tax liabilities declined 2% in the second quarter of 2008 compared to the decline of 8% in the second quarter of 2007.

Amortization of debt issue costs

In connection with our repurchase of $98.0 million principal amount of our senior
convertible notes in the first quarter of 2008, we expensed a portion of the unamortized debt issue costs related to the issue of these notes. As a result, our ongoing quarterly amortization expense relating to the remainder of the deferred debt
issue costs has decreased from $0.2 million per quarter to $0.1 million per quarter.

Recovery of (provision for) income taxes

We recorded a recovery of income taxes of $120.4 million in the second quarter of 2008. During the quarter, one of our foreign subsidiaries settled several ongoing tax
matters for less than had been accrued as part of its liability for unrecognized tax benefits resulting in the recognition of tax benefits of $124.1 million that were previously included in the liability for unrecognized tax benefits.

Net revenues for the first six months of 2008 were $264.9 million compared to $208.4 million for the same period
in 2007, an increase of $56.4 million, or 27%. Revenue generated from enterprise markets, which are served by our storage and microprocessor-based SOC products increased 31% compared to the same six months a year ago. Sales of our access-related
products increased by 91% compared to the same six months a year ago. This increase is primarily attributable to the growth in our fiber-to-the-home products in Asia. Sales to the communications market which are served by our WAN infrastructure and
wireless products increased by 3% from the same six months a year ago.

The growth in our enterprise storage sales was attributable to an increase in
storage capacity upgrades and information management solutions expenditures in the first six months of 2008. The sales of our microprocessor-based SOC products increased in the first six months of 2008 compared to the first six months of 2007
primarily due to increased activity in the laser printer market. The growth in our fiber-to-the-home sales was driven by an increase in shipments on a year-over-year basis as our Chinese customers delivered EPON devices to product field trials to
the China market. In addition, shipments to Japan and Korea increased as carriers build out their networks. Revenues from our WAN infrastructure products increased in the first six months of 2008 compared to the first six months 2007. The increase
was primarily attributable to changes in circumstances in how we conduct business with one of the international entities of a certain distributor to a sell-through basis, which is consistent with our revenue recognition practice for business
conducted in North America with that distributor.

Total gross profit increased $39.4 million, or 30%, in the first six months of 2008 compared to the same period in
2007. Gross profit as a percentage of revenues was 65% in the first six months of 2008 compared with 64% in the first six months of 2007.

While product
mix can influence our gross profit as a percentage of revenue from period to period, our underlying gross profit percentage in the first six months of 2008 remained consistent with that in the first six months of 2007 as changes in average selling
price decreased in approximately the same proportion as decreases in manufacturing costs.

Research and Development and Selling, General and Administrative Expenses

Our research and development, or R&D, expenses were $77.3 million, or $8.9 million and 10% lower in the first six months of 2008 compared to the first six months of
2007. Due to restructuring activities undertaken in the first quarter of 2007, our payroll-related costs decreased $6.7 million. Further in the first six months of 2008, we incurred $2.7 million less in materials costs due to completing fewer
tapeouts than in the first six months of 2007. Partially offsetting these decreases was a $0.5 million increase in infrastructure related expenses for normal maintenance of equipment and design related software tools.

Our selling, general and administrative, or SG&A, expenses were $48.4 million, or $3.5 million, or 7% lower in the first six months of 2008 compared to the first six
months of 2007. The primary reason for the net decrease in SG&A expenses is the restructuring activities undertaken in the first six months of 2007. As a result, payroll-related costs and facilities-related costs were lowered $2.7 million and
$1.9 million, respectively. Professional fees were $1.8 million lower in the first six months of 2008 compared to the first six months of 2007, mainly due to settlement of a litigation matter in August 2007. Other SG&A costs were $2.9 million
higher in the first six months of 2008 compared to the first six months of 2007. The primary reasons for the increase is that the Company received a credit of $2.8 million arising from the favorable settlements of both a payroll tax matter with the
United Kingdom tax authorities and a capital tax refund.

Amortization of purchased intangible assets and in-process research and development

In the first and second quarters of 2006, we completed the acquisitions of the Storage Semiconductor Business from Avago, and of Passave, Inc.,
respectively. Amortization of intangible assets acquired from the Storage Semiconductor Business and Passave in the first

six months of 2008 was $9.5 million and $10.2 million, respectively (amortization from the Storage Semiconductor Business and Passave in the first six months
of 2007 was $9.5 million and $10.2 million, respectively).

2007

In the first
quarter of 2007, we initiated a cost-reduction plan that involved staff reductions of 175 employees at various sites and the closure of design centers in Saskatoon, Saskatchewan and Winnipeg, Manitoba. We also vacated excess office space at the
Santa Clara, California facility. PMC continued to rationalize costs in the fourth quarter of 2007 by reducing headcount by 18 employees primarily at the Burnaby, British Columbia facility.

To date, we have incurred $10.5 million in termination and relocation costs, $3.0 million for excess facilities and $2.5 million in asset impairment charges.

We have made payments of $11.5 million in connection with this plan. As of June 29, 2008, $0.4 million in severance costs remained to be paid and payments
related to the excess facilities may extend until 2011.

2006

In the third quarter
of 2006, we closed our Ottawa, Ontario development site in order to reduce operating expenses and the space was vacated by the end of the fourth quarter of 2006. Approximately 35 positions were eliminated, primarily from research and development,
resulting in our recording restructuring charges for termination benefits, relocation costs and accrual for excess facilities. We also eliminated 10 positions from research and development in our Portland, Oregon development site, resulting in
restructuring charges for severance, excess facilities, contract termination costs and asset impairment.

In connection with these two activities, we have
recorded $2.5 million related to excess facilities and contract termination costs, $3.0 million in severance costs and $0.2 million in asset impairment charges, to date. In 2007, we reduced our estimated severance accrual by $0.3 million and our
accrual for excess facilities by $0.4 million, as we fulfilled a portion of these obligations. We have made payments of $4.1 million related to the 2006 plan. As of June 29, 2008, all severance costs have been paid and payments related to the
excess facilities will extend to 2010.

2005

During 2005, we
completed various restructuring activities aimed at streamlining production and reducing operating expenses. In the first quarter, we terminated 24 employees across all business functions. In the second quarter, we expanded the workforce reduction
activities initiated during the first quarter and terminated 63 employees from research and development located in the Santa Clara facility. In addition, we consolidated two manufacturing facilities (Santa Clara and Burnaby) into one facility
(Burnaby), which involved the termination of 26 employees from production control, quality assurance, and product engineering. In the third quarter, we consolidated its facilities and vacated excess space in the Santa Clara location.

In the first quarter of 2006, we continued the workforce reduction plans initiated in 2005, primarily in our research and development group, in the Santa Clara facility.

To date, we have recorded $6.3 million for excess facilities and contract termination costs, $9.2 million for termination benefits and $0.9 million
write-down of equipment and software assets whose assets were impaired as a result of this plan. In 2006, we reduced our accrual for termination benefits by $0.4 million as a portion of our obligation was fulfilled.

As of June 29, 2008, we have made payments relating to these activities of $12.7 million and all severance costs have been paid out. Payments related to the excess
facilities will extend to 2011.

2003 and 2001

In 2003 and
2001, we implemented three restructuring plans aimed at focusing development efforts on key projects and reducing operating costs in response to the severe and prolonged economic downturn in the semiconductor industry. Our assessment of the market
demand for our products, and the development efforts necessary to meet this demand, were key factors in the decisions to implement these restructuring plans. Cost reductions in all other functional areas were also implemented, as fewer resources
were required to support the reduced level of development and sales activities during these periods.

The January 2003 restructuring included the
termination of 175 employees and the closure of design centers in Maryland, Ireland and India, and vacating office space in the Santa Clara facility. To date, we have recorded restructuring charges of $18.3 million in accordance with SFAS
No. 146, Accounting for Costs Associated with Exit or Disposal Activities, including $1.5 million for asset write-downs. These charges related to workforce reduction, lease and contract settlement costs, and the write-down of
certain property, equipment and software assets whose value was impaired as a result of this restructuring plan. We have disposed of the property improvements and computer equipment, and software licenses have been cancelled or are no longer being
used. In 2006, we reversed $2.3 million of this restructuring accrual because certain floors in the Santa Clara facility that had been vacated in 2003 were re-occupied in 2006 due to the addition of personnel that occurred with the acquisition of
the Storage Semiconductor Business. We reversed an additional $0.5 million in 2007 as we completed a portion of the lease obligation at this site.

The
October 2001 restructuring plan included the termination of 341 employees, the consolidation of excess facilities, and the curtailment of certain research and development projects, resulting in a restructuring charge of $175.3 million, including
$12.2 million of asset write-downs. Due to the continued downturn in real estate markets, we recorded additional provisions for abandoned office facilities of $1.3 million in the fourth quarter of 2004.

In the first quarter of 2001, we recorded a charge of $19.9 million for a restructuring plan that included the termination of 223 employees across all business
functions, the consolidation of a number of facilities and the curtailment of certain research and development projects. Due to the continued downturn in real estate markets, we have recorded additional provisions for abandoned office facilities
totaling $3.9 million since 2004.

To date, we have made cash payments of $13.3 million and $178.1 million related to the 2003 and 2001 plans,
respectively. We have completed the activities contemplated in these restructuring plans, but have not yet terminated the leases on all of its surplus facilities. Efforts to exit these sites are ongoing, but the payments related to these facilities
could extend to 2011.

Interest income, net

Interest income was $3.6 million in the first six months of 2008 compared to $4.3 million in the first six months of 2007, a decrease of $0.7 million. This decrease is attributable primarily to lower yields earned on investments in the
first six months of 2008 compared to the first six months of 2007, partially offset by a decrease in interest expense incurred on the senior convertible notes due to the partial repurchase of these notes in the first six months of 2008.

Foreign exchange gain (loss)

Our net foreign exchange gain was
$2.1 million in the first six months of 2008, which was primarily due to a $2.8 million foreign exchange gain on the revaluation of our net tax liability in a foreign jurisdiction. The revaluation of this foreign tax liability was required because
of depreciation of other currencies against the United States Dollar. In the first six months of 2007, our net foreign exchange loss was $8.9 million, which was primarily due to a $9.3 million foreign exchange loss on the revaluation of our net tax
liability in a foreign jurisdiction.

The value of the US dollar relative to the Canadian dollar increased 2% in the first half of 2008 compared to
declining 9% in the first half of 2007.

Gain on repurchase of senior convertible notes and amortization of debt issue costs

In the first three months of 2008, we repurchased $98.0 million principal amount of our senior convertible notes for $94.5 million and expensed $2.2 million of related
unamortized debt issue costs and transaction costs, resulting in a net gain of $1.3 million. We expensed $0.3 million of the remaining unamortized debt issue costs in the first six months of 2008, compared to $0.5 million in the first six months of
2007.

Recovery of income taxes

We recorded a recovery of income taxes of $81.7 million in the first six months of 2008. During the first quarter of 2008, one of the Companys foreign subsidiaries received a written communication from a tax authority pertaining to
its 2000 tax year, resulting in an additional accrual of $26.5 million, including interest, as part of its liability for unrecognized tax benefits. In the second quarter of 2008, this subsidiary settled several ongoing tax matters for less than had
been accrued as part of its liability for unrecognized tax benefits, resulting in the recognition of tax benefits of $124.1 million that were previously included in the liability for unrecognized tax benefits.

We recorded a recovery of income taxes of $2.3 million in the first six months of 2007, including a $4.0 million tax recovery relating to the settlement of prior
years tax credits.

Critical Accounting Estimates

General

Managements Discussion and Analysis of Financial Condition and Results of Operations is based upon our
condensed consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires us to make estimates and assumptions that
affect our reported assets, liabilities, revenue and expenses, and related disclosure of our contingent assets and liabilities. Our significant accounting policies are outlined in Note 1 to the condensed consolidated financial statements in our
Annual Report on Form 10-K for the year ended December 30, 2007, which also provides commentary on our most critical accounting estimates. The following estimates are of note:

Valuation of Goodwill and Intangible Assets

The
purchase method of accounting for acquisitions requires estimates and assumptions to allocate the purchase price to the fair value of net tangible and intangible assets acquired, including in-process research and development (IPR&D). The amounts
allocated to IPR&D are expensed immediately. The amounts allocated to, and the useful lives estimated for, other intangible assets, affect future amortization. There are a number of generally accepted valuation methods used to estimate fair
value of intangible assets, and we use primarily a discounted cash flow method, which requires significant management judgment to forecast the future operating results and to estimate the discount factors used in the analysis. If assumptions and
estimates used to allocate the purchase price prove to be inaccurate based on actual results, future asset impairment charges could be required.

Goodwill
and intangible assets determined to have indefinite lives are not amortized, but are subject to an annual impairment test. To determine any goodwill impairment, we perform a two-step process on an annual basis, or more frequently if necessary, to
determine 1) whether the fair value of the relevant reporting unit exceeds carrying value and 2) to measure the amount of



- 33 -

##### Table of Contents

an impairment loss, if any. We review our intangible assets for impairment whenever events or changes in circumstances indicate that their carrying value may
not be recoverable. Measurement of an impairment loss is based on the fair value of the asset compared to carrying value.

In 2007, we recorded additional
goodwill related to the acquisition of Passave, Inc. This adjustment was based on our estimate of costs to settle a legal matter that existed at the time of acquisition.

There were no indications of impairment to goodwill or intangible assets during the six months ended June 29, 2008. Changes in the estimated fair values of these assets in the future could result in significant
impairment charges or changes to our expected amortization.

Stock-based compensation

On January 1, 2006, we adopted SFAS 123(R), which requires the recognition of compensation expense for all share-based payment awards. Under SFAS 123(R) we measure
the fair value of awards of equity instruments and recognize the cost, net of an estimated forfeiture rate, on a straight-line basis over the period during which services are provided in exchange for the award, generally the vesting period.

Calculating the fair value of stock-based compensation awards requires the input of highly subjective assumptions, including the expected life of the
awards and expected volatility of PMCs stock price. Expected volatility is a statistical measure of the amount by which a stock price is expected to fluctuate during a period. Our estimates of expected volatilities are based on a weighted
historical and market-based implied volatilities. In order to determine the expected life of the awards, we use historical data to estimate option exercises and employee terminations; separate groups of employees that have similar historical
exercise behavior, such as directors or executives, are considered separately for valuation purposes. The expected forfeiture rate applied in calculating stock-based compensation cost is estimated using historical data.

The assumptions used in calculating the fair value of stock-based awards involve estimates that require management judgment. If factors change and we use different
assumptions, our stock-based compensation expense could change significantly in the future. In addition, if our actual forfeiture rate is different from our estimate, our stock-based compensation expense could change significantly in the future. See
Notes 1 and 4 to the condensed consolidated financial statements for further information on stock-based compensation.

Restructuring
chargesFacilities

In calculating the cost to dispose of our excess facilities, we had to estimate the amount to be paid in lease termination
payments, the future lease and operating costs to be paid until the lease is terminated, and the amount, if any, of sublease revenues for each location. This required us to estimate the timing and costs of each lease to be terminated, the amount of
operating costs for the affected facilities, and the timing and rate at which we might be able to sublease or complete negotiations of a lease termination agreement for each site. To form our estimates for these costs we performed an assessment of
the affected facilities and considered the current market conditions for each site.



- 34 -

##### Table of Contents

For example, we have recorded charges of $3.0 million to date, relating to the restructuring of excess facilities in
connection with our 2007 restructuring plan. This estimate represents 100% of the estimated future operating costs and lease obligation for the exited space.

We believe our estimates of the obligations for the closing of sites remain sufficient to cover anticipated settlement costs. However, our assumptions on either the lease termination payments, operating costs until the termination, or the
amounts and timing of offsetting sublease revenues may turn out to be incorrect and our actual cost may be materially different from our estimates. If our actual costs exceed our estimates, we would incur additional expenses in future periods.

Income Taxes

In estimating our annual
effective tax rate we review our forecasted net income for the year by geographic area and apply the appropriate tax rates. We also consider the income tax credits available in each tax jurisdiction.

Our operations are conducted in a number of countries with complex tax legislation and regulations pertaining to our business activities. We have recorded income tax
liabilities based on our estimates and interpretations of those regulations for the countries we operate in. However our estimates are subject to review and assessment by the tax authorities and the courts of those countries. The timing of any such
review and final assessment of our liabilities by local authorities is substantially out of our control and is dependent on the actions by those authorities in the countries in which we operate. Any re-assessment or proposed adjustment of our tax
liabilities by tax authorities may result in adjustments of the income taxes and the assessment of interest and penalties that we pay or refunds that are due to us.

During the second fiscal quarter, our liability for unrecognized tax benefits decreased by $171.6 million to $33.0 million. This substantial decrease was primarily the result of a foreign subsidiary settling several
ongoing tax matters related to prior years for amounts less than were accrued as unrecognized tax benefits.

In certain jurisdictions we have incurred
losses and other costs that can be applied against future taxable earnings to reduce our tax liability on those earnings. As we are uncertain of realizing the future benefit of those losses and expenditures, we have taken a valuation allowance
against all domestic deferred tax assets and certain foreign deferred tax assets.

Business Outlook

We expect our revenues for the third quarter of 2008 to be in the range of $136.0 million to $141.0 million. As in the past, and consistent with business practice in the
semiconductor industry, a significant portion of our revenues are likely to be derived from orders received and shipped during the same quarter, which we call our turns business. Our revenue outlook for the third quarter of 2008 depends
in part on achieving 26% of our revenues from our turns business to reach the mid-point of the revenue range. Our quarterly revenues may vary considerably as our customers adjust to fluctuating demand for products in their markets.

##### Table of Contents

We anticipate our third quarter 2008 gross margins to be approximately the same as the second quarter of 2008, inclusive
of $0.3 million stock based compensation expense. As in past quarters this could vary depending on the volumes of products sold, since many of our costs are fixed. Margins will also vary depending on the mix of products sold.

We expect our third quarter 2008 operating expenses before acquisition-related costs to be approximately $63.6 million to $64.6 million including stock-based
compensation expense of approximately $5.9 million. We anticipate that interest and other income in the third quarter of 2008 will be approximately $1.0 million.

In the second quarter of 2008, our Chief Executive Officer and President, Robert Bailey, retired from these positions. Gregory Lang was appointed to these roles after our report on Form 10-Q for the first quarter of 2008 was filed.
Mr. Bailey is continuing as Chairman of the Board of Directors.

Liquidity & Capital Resources

Our principal source of liquidity at June 29, 2008 was our $322.3 million in cash and cash equivalents.

In the first six months of 2008, we generated $53.1 million of cash from operating activities.

Significant changes in working capital accounts included:



| |  |  | a $5.7 million increase in accounts receivable, primarily as a result of increased revenues.

Purchase obligations as noted in the above table are comprised of commitments to purchase design tools and
software for use in product development. Excluded from these purchase obligations are commitments for inventory or other expenses entered into in the normal course of business. We estimate these other commitments to be approximately $13.8 million at
June 29, 2008 for inventory and other expenses that will be received within 90 days and that will require settlement 30 days thereafter.

We expect to
use approximately $15.6 million of cash in the remainder of 2008 for capital expenditures and purchases of intellectual property.

During the first six
months of 2008, we settled several ongoing tax matters with a foreign tax authority. As part of the settlement, we agreed to pay $18.0 million and utilize $31.6 million net investment tax credits. Because we settled these matters for less than we
accrued as unrecognized tax benefits, we reversed $124.1 million of amounts previously accrued in accordance with FIN 48 related to these tax matters.

Based on our current operating prospects, we believe that existing sources of liquidity will satisfy our projected operating, working capital, investing, capital expenditure, wafer deposit and remaining restructuring requirements through
2008.



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

The
following discussion regarding our risk management activities contains forward-looking statements that involve risks and uncertainties. Actual results may differ materially from those projected in the forward-looking statements.

##### Table of Contents

Cash Equivalents and Short-term Investments:

We regularly maintain a short and long term investment portfolio of various types of government and corporate bonds and notes. Our investments are made in accordance with
an investment policy approved by our Board of Directors. Maturities of these instruments are less than 30 months with the majority being within one year. To minimize credit risk, we diversify our investments and select minimum ratings of P-1 or A by
Moodys, or A-1 or A by Standard and Poors, or equivalent. We classify these securities as available-for-sale and they are carried at fair market value. Our corporate policies prevent us from holding material amounts of asset-backed
commercial paper.

Investments in instruments with both fixed and floating rates carry a degree of interest rate risk. Fixed rate securities may have their
fair market value adversely impacted because of a rise in interest rates, while floating rate securities may produce less income than expected if interest rates fall. Due in part to these factors, our future investment income may fall short of
expectations because of changes in interest rates, or we may suffer losses in principal if we were to sell securities that have declined in market value because of changes in interest rates.

We do not attempt to reduce or eliminate our exposure to interest rate risk through the use of derivative financial instruments.

Senior Convertible Notes:

At June 29, 2008,
$127.0 million of our 2.25% senior convertible notes were outstanding. Because we pay fixed interest coupons on our notes, market interest rate fluctuations do not impact our debt interest payments. However, the fair value of our senior convertible
notes will fluctuate as a result of changes in the price of our common stock, changes in market interest rates and changes in our credit worthiness.

Our
2.25% senior convertible notes are not listed on any securities exchange or included in any automated quotation system, but are registered for resale under the Securities Act of 1933.

The notes rank equal in right of payment with our other unsecured senior indebtedness and mature on October 15, 2025 unless earlier redeemed by us at our option, or converted or put to us at the option of the
holders. Interest is payable semi-annually in arrears on April 15 and October 15 of each year, commencing on April 15, 2006. We may redeem all or a portion of the notes at par on and after October 20, 2012. We redeemed $98.0
million of the principal of these notes in the first quarter of 2008 at a cost of $95.5 million, including transaction fees and accrued interest. The holders may require that we repurchase the notes on October 15, 2012, 2015 and 2020,
respectively.

Holders may convert the notes into the right to receive the conversion value (i) when our stock price exceeds 120% of the approximately
$8.80 per share initial conversion price for a specified period, (ii) in certain change in control transactions, and (iii) when the trading price of the notes does not exceed a minimum price level. For each $1,000 principal amount of
notes, the conversion value represents the amount equal to 113.6687 shares multiplied by the per share price of our common stock at the time of conversion. If the conversion value exceeds $1,000 per $1,000 in principal of notes, we will pay $1,000
in cash and may pay the amount exceeding $1,000 in cash, stock or a combination of cash and stock, at our election.

##### Table of Contents

Foreign Currency:

Our sales and corresponding receivables are denominated primarily in United States dollars. We generate a significant portion of our revenues from sales to customers located outside the United States including Canada,
Europe, the Middle East and Asia. We are subject to risks typical of an international business including, but not limited to, differing economic conditions, changes in political climate, differing tax structures, other regulations and restrictions
and foreign exchange rate volatility. Accordingly, our future results could be materially adversely affected by changes in these or other factors.

Through
our operations in outside the United States, we incur research and development, sales, customer support and administrative expenses in foreign currencies. We are exposed, in the normal course of business, to foreign currency risks on these
expenditures. In our effort to manage such risks, we have adopted a foreign currency risk management policy intended to reduce the effects of potential short-term fluctuations on our operating results stemming from our exposure to these risks. As
part of this risk management, we enter into foreign exchange forward contracts on behalf of our Canadian subsidiary. These forward contracts offset the impact of exchange rate fluctuations on forecasted cash flows or firm commitments. We limit the
forward contracts operational period to 12 months or less and we do not enter into foreign exchange forward contracts for trading purposes. Because we do not engage in foreign exchange risk management techniques beyond these periods, our cost
structure is subject to long-term changes in foreign exchange rates.

At June 29, 2008, we had six contracts outstanding to purchase Canadian dollars,
all with maturities of less than twelve months that qualified and were designated as cash flow hedges. The U.S. dollar notional amount of these contracts was $29.6 million and the contracts had a fair value of $(1.0) million.

We attempt to limit our exposure to foreign exchange rate fluctuations from our foreign currency net asset or liability positions. We hedge less than twenty percent of
our accruals for foreign income taxes in the ordinary course of business, and consequently in the first six months of 2008 we recorded a $2.8 million foreign exchange gain relating to this item. The revaluation of our foreign income tax liability
was required because of fluctuations in the value of the United States dollar against other currencies. Our operating income would be materially impacted by a shift in the foreign exchange rates between United States and foreign currencies that are
material to our business. For example, if the value of the United States dollar decreased by an additional 5% relative to foreign currencies material to our business, our income before recovery of income taxes would decrease by approximately $2.0
million.

##### Table of Contents

Other Investments:

Our other investments include strategic investments in privately held companies that are carried on our balance sheet at cost, net of write-downs for non-temporary declines in market value. We expect to make
additional investments like these in the future. These investments are inherently risky, as they typically are comprised of investments in companies and partnerships that are still in the start-up or development stages. The market for the
technologies or products that they have under development is typically in the early stages, and may never materialize. We could lose our entire investment in these companies and partnerships or may incur an additional expense if we determine that
the value of these assets has been impaired. We may record an impairment charge to our operating results should we determine that these funds have incurred a non-temporary decline in value.



|Item 4. | CONTROLS AND PROCEDURES
|------- | -----------------------

Evaluation of
disclosure controls and procedures

Our management evaluated, with the participation of our chief executive officer and our chief financial officer, our
disclosure controls and procedures as of the end of the period covered by this quarterly report. Based on this evaluation, our chief executive officer and our chief financial officer concluded that our disclosure controls and procedures are
effective to ensure that information we are required to disclose in reports that we file or submit under the Securities Exchange Act of 1934 is accumulated and communicated to management, including our chief executive officer and our chief financial
officer, as appropriate, to allow timely decisions regarding required disclosure, and is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission rules and forms.

Changes in internal control over financial reporting

There was no change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15(d)-15(f) under the Exchange Act) that occurred during the three month period ended June 29, 2008 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
|------- | -----------------

Stockholder Derivative Lawsuits

Three derivative actions have been filed against the Company, as a nominal defendant, and various current and former officers and/or
directors: (1) Meissner v. Bailey, et al., Santa Clara Superior Court Case No. 1-06-CV-071329 (filed September 18, 2006); (2) Beiser v. Bailey, et al., United States District Court for the Northern District of
California (the Federal Court) Case No. 5:06-CV-05330-RS (filed August 29, 2006); and (3) Barone v. Bailey, et al., United States District Court for the Northern District of California Case
No. 4:06-CV-06473-SBA (filed October 16, 2006). On November 21, 2006, the Beiser and Barone actions were consolidated into one case. On January 18, 2007, the Santa Clara County Superior Court in California ordered that
the Meissner action be stayed pending the outcome of the consolidated, federal Beiser/Barone action.

The Beiser/Barone plaintiffs generally allege that
various current and former Company directors and/or officers breached their duty of loyalty and/or duty of care to the Company and its stockholders and that these purported breaches of fiduciary duties caused harm to the Company. The plaintiffs seek
to recover damages on behalf of the Company. They also allege violations of federal securities laws. The Company is a nominal defendant, but any recovery in the litigation would be paid to the Company, rather than to its
stockholders. The defendants have entered into joint defense arrangements.

The defendants moved to dismiss the Besier/Barone action on various legal
grounds including that the plaintiffs failed to state a claim and failed to plead with particularity facts establishing that a litigation demand on the board of directors of the Company would have been futile at the time they commenced
the derivative lawsuit. The Federal Court dismissed the consolidated complaint on August 22, 2007 and gave plaintiffs leave to amend. The Federal Court dismissed the plaintiffs first amended consolidated complaint on May 8,
2008 and permitted plaintiffs leave to amend one last time. Defendants moved to dismiss the second amended complaint which motions will be heard on August 20, 2008.

On July 18, 2008, Ian Beiser, a plaintiff in the Beiser/Barone action, filed a complaint in the Delaware Court of Chancery compelling the Company to permit plaintiff to inspect and make copies of the
Companys books and records. The Company intends to move to dismiss Beisers complaint on or before August 7, 2008. Beiser/Barone had previously filed a motion to compel production of the Companys books and records in the
Federal Court, which motion was denied on May 8, 2008.

At June 29, 2008, we have not accrued costs for potential losses related to the
Beiser/Barone action.

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

Our company is subject to a number of
risks  some are normal to the fabless semiconductor industry, some are the same or similar to those disclosed in previous SEC filings, and some may be present in the future. You should carefully consider all of these risks and the other
information in this report before investing in PMC. The fact that certain risks are endemic to the industry does not lessen the significance of the risk.

As a result of the following risks, our business, financial condition, operating results and/or liquidity could be materially adversely affected. This could cause the trading price of our securities to decline, and
you may lose part or all of your investment.

We are subject to rapid changes in demand for our products due to:



| |  |  | variations in our turns business;
| | - |  | ---------------------------------



| |  |  | short order lead time;
| | - |  | ----------------------



| |  |  | customer inventory levels;
| | - |  | --------------------------



| |  |  | production schedules; and
| | - |  | -------------------------



| |  |  | fluctuations in demand.
| | - |  | -----------------------

Our revenues and profits
may fluctuate because of factors that are beyond our control. As a result, we may fail to meet the expectations of security analysts and investors, which could cause our stock price to decline.

Our ability to project revenues is limited because a significant portion of our quarterly revenues may be derived from orders placed and shipped in the
same quarter, which we call our turns business. Our turns business varies widely from quarter to quarter. Our customers may delay product orders and reduce delivery lead-time expectations, which may reduce our ability to project revenues
beyond the current quarter. While we regularly evaluate end users and contract manufacturers inventory levels of our products to assess the impact of their inventories on our projected turns business, we do not have complete information
on their inventories. This could cause our projections of a quarters turns business to be inaccurate, leading to lower revenues than projected.

##### Table of Contents

We may fail to meet our forecasts if our customers cancel or delay the purchase of our products or if we are unable to
meet their demand.

We rely on customer forecasts in order to estimate the appropriate levels of inventory to build and to project our
future revenues. Many of our customers have numerous product lines, numerous component requirements for each product, sizeable and complex supplier structures, and typically engage contract manufacturers for additional manufacturing capacity. This
complex supply chain creates several variables that make it complicated to accurately forecast our customers demand and accurately monitor their inventory levels of our products. If customer forecasts are not accurate, we may build too much
inventory, potentially leaving us with excess and obsolete inventory, which would reduce our profit margins and adversely affect our operating results. Conversely, we may build too little inventory to meet customer demand causing us to miss
revenue-generating opportunities. The cancellation or deferral of product orders, the return of previously sold products or overproduction due to the failure of anticipated orders to materialize could result in our holding excess or obsolete
inventory, which could result in write-downs of inventory. This difficulty may be compounded when we sell to OEMs indirectly through distributors and other resellers or contract manufacturers, or both, as our forecasts of demand are then based on
estimates provided by multiple parties.

Our customers often shift buying patterns as they manage inventory levels, market different
products, or change production schedules. This makes forecasting their production requirements difficult and can lead to an inventory surplus or shortage of certain of their components. In addition, our products vary in terms of profit margins they
generate. If our customers purchase a greater proportion of our lower margin parts in a particular period, it would adversely impact our results of operations.

Further, our distributors provide us with periodic reports of their backlog to end customers, sales to end customers and quantities of our products that they have on hand. If the data that is provided to us is
inaccurate, it could lead to inaccurate forecasting of our revenues or errors in our reported revenues, gross profit and net income.

While
backlog is our best estimate of our next quarters revenues, it is industry practice to allow customers to cancel, change or defer orders with limited advance notice prior to shipment. As such, backlog may be an unreliable indicator of future
revenue levels. Because a significant portion of our operating expenses is fixed, even a small revenue shortfall can have a disproportionately negative effect on our operating results.

If the demand for our customers products declines, demand for our products will be similarly affected and our revenues, gross margins and operating performance will be adversely affected.

Our customers are subject to their own business cycles, most of which are unpredictable in commencement, depth and duration. We cannot accurately predict
the continued demand of our customers products and the demands of our customers for our products. In the past, networking customers have reduced capital spending without notice, adversely affecting our revenues. As a result of this
uncertainty, our past operating results may not be indicative of our future operating results. It is possible that, in future periods, our results may be below the expectations of public market analysts and investors. This could cause the market
price of our common stock to decline.

##### Table of Contents

We rely on a few customers for a major portion of our sales, any one of which could materially impact our revenues
should they change their ordering pattern. The loss of a key customer could materially impact our results of operations.

We depend on
a limited number of customers for large portions of our revenues. For example, through direct, distributor and subcontractor purchases, Cisco Systems and HP Corporation have historically each accounted for more than 10% of our revenues. As at
June 29, 2008, we did not have any customers that accounted for more than 10% of our revenues. We do not have long-term volume purchase commitments from any of our major customers. We sell our products solely on the basis of purchase orders.
Those customers could decide to cease purchasing products with little or no notice and without significant penalties. A number of factors could cause our customers to cancel or defer orders, including interruptions to their operations due to a
downturn in their industries, delays in manufacturing their own product offerings into which our products are incorporated, and natural disasters. Accordingly, our future operating results will continue to depend on the success of our largest
customers and on our ability to sell existing and new products to these customers in significant quantities.

The loss of a key customer,
or a reduction in our sales to any major customer or our inability to attract new significant customers could materially and adversely affect our business, financial condition or results of operations.

The loss of personnel could delay us from designing new products.

To succeed, we must retain and hire technical personnel highly skilled at the design and test functions needed to develop high-speed networking products. The competition for such employees is intense.

We do not have employment agreements in place with many of our key personnel. As employee incentives, we issue common stock options and restricted stock
grants that are subject to time vesting, and, in the case of options, have exercise prices at the market value on the grant date. As our stock price varies substantially, the equity awards to employees are effective as retention incentives only if
they have economic value.

Changes in our management may cause uncertainty, in or be disruptive to, our business.

In May 2008, Gregory Lang became our Chief Executive Officer and President upon, Robert Baileys retirement from these positions Mr. Bailey is
continuing in the role of Chairman of the Board of Directors. We may experience transition issues among our senior management team and in our operations during the Chief Executive Officer transition, potentially leading to attrition and loss of
productivity.

Changes in the political and economic climate in the countries we do business may adversely affect our operating
results

We earn a substantial portion of our revenues in Asia. We conduct an increasing portion of our research and development and
manufacturing activities outside North America. We procure substantially all of our wafers from Taiwan and use assemblers throughout Asia.

Given the depth of our sales and operations in Asia, we face risks that could negatively impact our results of operations, including economic sanctions imposed by the U.S. government, imposition of tariffs and other potential trade barriers
or regulations, uncertain protection for intellectual property rights and generally longer receivable collection periods.

Our results of
operations are increasingly dependent on our sales in China, which accounted for 31% of our revenues in second quarter of 2008. Government agencies in China have broad discretion and authority over all aspects of the telecommunications and
information technology industry in China; accordingly their decisions may impact our ability to do business in China. Therefore, significant changes in Chinas political and economic conditions and governmental policies could have a substantial
impact on our business. The growth of FTTH technology in China has continued to be strong; however, a slowdown in that growth would have an adverse impact on our operating results.

In addition to selling our products in a number of countries, an increasing portion of our research and development and manufacturing is conducted
outside North America, in particular, India and China. The geographic diversity of our business operations could hinder our ability to coordinate design, manufacturing and sales activities. If we are unable to develop systems and communication
processes to support our geographic diversity, we may suffer product development delays or strained customer relationships.

Hostilities in the Middle
East may have a significant impact on our Israeli subsidiarys ability to conduct its business.

One of our research and
development facilities is located in Israel, and employs approximately 170 people. On an on-going basis, some of our Israeli employees are periodically called into active military duty. In the event of severe hostilities breaking out, a significant
number of our Israeli employees may be called into active military duty, resulting in delays, including product development schedules.

Our revenues may
decline if we do not maintain a competitive portfolio of products.

We are experiencing significantly greater competition from many
different market participants as the market in which we participate matures. In addition, we are expanding into markets, such as the wireless infrastructure, enterprise storage, customer premise equipment, and generic microprocessor markets, which
have established incumbents with substantial financial and technological resources. We expect more intense competition than that which we have traditionally faced as some of these incumbents derive a majority of their earnings from these markets.

##### Table of Contents

We typically face competition at the design stage, where customers evaluate alternative design approaches
requiring integrated circuits. The markets for our products are intensely competitive and subject to rapid technological advancement in design tools, wafer manufacturing techniques, process tools and alternate networking technologies. We may not be
able to develop new products at competitive pricing and performance levels. Even if we are able to do so, we may not complete a new product and introduce it to market in a timely manner. Our customers may substitute use of our products in their next
generation equipment with those of current or future competitors, reducing our future revenues. With the shortening product life and design-in cycles in many of our customers products, our competitors may have more opportunities to supplant
our products in next generation systems.

Our customers are increasingly price conscious, as semiconductors sourced from third party
suppliers comprise a greater portion of the total materials cost in networking equipment. We continue to experience aggressive price competition from competitors that wish to enter into the market segments in which we participate. These
circumstances may make some of our products less competitive, and we may be forced to decrease our prices significantly to win a design. We may lose design opportunities or may experience overall declines in gross margins as a result of increased
price competition.

Over the next few years, we expect additional competitors, some of which may also have greater financial and other
resources, to enter these markets with new products. These companies, individually or collectively, could represent future competition for many design wins, and subsequent product sales.

Design wins do not translate into near-term revenues and the timing of revenues from newly designed products is often uncertain.

From time to time, we announce new products and design wins for existing and new products. While some industry analysts may use design wins as a metric for future revenues, many design wins have not, and will not,
generate any revenues for us, as customer projects are cancelled or unsuccessful in their end market. In the event a design win generates revenues, the amount of revenues will vary greatly from one design win to another. In addition, most
revenue-generating design wins do not translate into near-term revenues. Most revenue-generating design wins take more than two years to generate meaningful revenues.

We may be unsuccessful in transitioning the design of our new products to new manufacturing processes.

Many of our new products are designed to take advantage of new manufacturing processes offering smaller device geometries as they become available, since smaller geometries can provide a product with improved features such as lower power
requirements, increased performance, more functionality and lower cost. We believe that the transition of our products to, and introduction of new products using, smaller device geometries is critical for us to remain competitive. We could
experience difficulties in migrating to future smaller device geometries or manufacturing processes, which would result in the delay of the production of our products. Our products may become obsolete during these delays, or allow competitors
parts to be chosen by customers during the design process.

##### Table of Contents

Since many of the products we develop do not reach full production sales volumes for a number of years, we may
incorrectly anticipate market demand and develop products that achieve little or no market acceptance.

Our products generally take
between 12 and 24 months from initial conceptualization to development of a viable prototype, and another 3 to 18 months to be designed into our customers equipment and sold in production quantities. We sell products whose characteristics
include evolving industry standards, short product life spans and new manufacturing and design technologies. Our products often must be redesigned because manufacturing yields on prototypes are unacceptable or customers redefine their products to
meet changing industry standards or customer specifications. As a result, we develop products many years before volume production and may inaccurately anticipate our customers needs. Redesigning our products is expensive and may delay
production of our products. Our products may become obsolete during these delays, resulting in our inability to recoup our initial investments in product development.

The final determination of our income tax liability may be materially different from our income tax provision.

We are subject to income taxes in both the United States and international jurisdictions. Significant judgment is required in determining our worldwide provision for income taxes. In the ordinary course of our
business, there are many transactions where the ultimate tax determination is uncertain. Additionally our calculations of income taxes are based on our interpretations of applicable tax laws in the jurisdictions in which we file. Although we believe
our tax estimates are reasonable, there is no assurance that the final determination of our income tax liability will not be materially different than what is reflected in our income tax provisions and accruals. Should additional taxes be assessed
as a result of new legislation, an audit or litigation, if our effective tax rate should change as a result of changes in federal, international or state and local tax laws, or if we were to change the locations where we operate, there could be a
material effect on our income tax provision and results of operations in the period or periods in which that determination is made, and potentially to future periods as well. During the second quarter of 2008, the Company and a foreign tax authority
settled a dispute pertaining to the Companys 2000 to 2006 tax years in that jurisdiction. As a result of this settlement, we reversed $124.1 million of our FIN 48 reserve for unrecognized tax benefits.

We have applied the guidance in FIN 48 in determining our accrued liability for unrecognized tax benefits, which totals $33.0 million on a world-wide consolidated basis
as at June 29, 2008. The ultimate resolution of outstanding tax matters could be for amounts in excess of our reserves established in accordance with FIN 48. Such events could have a material adverse effect on our liquidity or cash flows in the
quarter in which an adjustment is recorded or the tax payment is due.

If foreign exchange rates fluctuate significantly, our profitability may decline.

We are exposed to foreign currency rate fluctuations because a significant part of our development, test, and selling and administrative costs are
incurred in foreign currencies. The U.S. dollar has devalued significantly compared to the Canadian dollar and this trend may continue. To protect against reductions in value and the volatility of future cash flows caused by changes in foreign
exchange rates, we enter into foreign currency forward contracts. The contracts reduce, but do not eliminate, the impact of foreign currency exchange rate movements. In addition, this foreign currency risk management policy may not be effective in
addressing long-term fluctuations since our contracts do not extend beyond a 12-month maturity.

We regularly limit our exposure to foreign
exchange rate fluctuations from our foreign net asset or liability positions. Our accrual for foreign income taxes is partially hedged against foreign exchange gains and losses, however, we recorded a net $1.1 million foreign exchange loss on the
revaluation of our income tax liability, net of deferred tax assets, in the second quarter of 2008 because of fluctuations in the United States dollar against foreign currencies. Our profitability would be materially impacted by a 5% shift in the
foreign exchange rates between United States dollar and foreign currencies that are material to our business.

We are exposed to the credit risk of some
of our customers.

Many of our customers employ contract manufacturers to produce their products and manage their inventories. Many of
these contract manufacturers represent greater credit risk than our OEM customers, who do not guarantee our credit receivables related to their contract manufacturers.

In addition, a significant portion of our sales flows through our distribution channel, which generally represents a higher credit risk. Should these companies encounter financial difficulties, our revenues could
decrease, and collection of our significant accounts receivables with these companies could be jeopardized.

Our business strategy contemplates
acquisition of other products, technologies, or businesses, which could adversely affect our operating performance.

Acquiring
products, intellectual property, technologies, and businesses from third parties is a core part of our business strategy. That strategy depends on the availability of suitable acquisition candidates at reasonable prices and our ability to resolve
challenges associated with integrating acquired businesses into our existing business. These challenges include integration of product lines, sales forces, customer lists and manufacturing facilities, development of expertise outside our existing
business, diversion of management time and resources, possible divestitures, inventory write-offs and other charges. We also may be forced to replace key personnel who may leave our Company as a result of an acquisition. We cannot be certain that we
will find suitable acquisition candidates or that we will be able to meet these challenges successfully. Acquisitions could also result in customer dissatisfaction, performance problems with the acquired company, investment, or technology, the
assumption of contingent liabilities, or other unanticipated events or circumstances, any of which could harm our business. Consequently, we might not be successful in integrating any acquired businesses products or technologies and may not achieve
anticipated revenues and costs benefits.

##### Table of Contents

An acquisition could absorb substantial cash resources, require us to incur or assume debt obligations,
or issue additional equity. If we are not able to obtain financing, then we may not be in a position to consummate acquisitions. If we issue equity securities in connection with an acquisition, we may dilute our common stock with securities that
have an equal or a senior interest in our Company.

From time to time, we license, or acquire, technology from third parties to incorporate into our
products. Incorporating technology into our products may be more costly or more difficult than expected, or require additional management attention to achieve the desired functionality. The complexity of our products could result in unforeseen or
undetected defects or bugs, which could adversely affect the market acceptance of new products and damage our reputation with current or prospective customers.

Our current product road map will, in part, be dependent on successful acquisition and integration of intellectual property cores developed by third parties. If we experience difficulties in obtaining or integrating
intellectual property from these third parties, it could delay or prevent the development of our products in the future.

Although our
customers, our suppliers, and we rigorously test our products, our highly complex products may contain defects or bugs. We have in the past experienced, and may in the future experience, defects and bugs in our products. If any of our products
contain defects or bugs, or have reliability, quality or compatibility problems that are significant to our customers, our reputation may be damaged and customers may be reluctant to buy our products. This could materially and adversely affect our
ability to retain existing customers or attract new customers. In addition, these defects or bugs could interrupt or delay sales to our customers.

We may have to invest significant capital and other resources to alleviate problems with our products. If any of these problems are not found until after we have commenced commercial production of a new product, we may be required to incur
additional development costs and product recall, repair or replacement costs. These problems may also result in claims against us by our customers or others. In addition, these problems may divert our technical and other resources from other
development efforts. Moreover, we would likely lose, or experience a delay in, market acceptance of the affected product or products, and we could lose credibility with our current and prospective customers.

Our business may be adversely affected if our customers or suppliers cannot obtain sufficient supplies of other components needed in their product offerings to meet
their production projections and target quantities.

Some of our products are used by customers in conjunction with a number of other
components, such as transceivers, microcontrollers and digital signal processors. If, for any reason, our customers experience a shortage of any component, their ability to produce the

##### Table of Contents

forecasted quantity of their product offerings may be affected adversely and our product sales would decline until the shortage is remedied. Such a situation
could harm our operating results, cash flow and financial condition.

We rely on limited sources of wafer fabrication, the loss of which could delay and
limit our product shipments.

We do not own or operate a wafer fabrication facility. In 2007, two outside wafer foundries supplied more
than 95% of our semiconductor wafer requirements. Our wafer foundry suppliers also make products for other companies and some make products for themselves, thus we may not have access to adequate capacity or certain process technologies. We have
less control over delivery schedules, manufacturing yields and costs than competitors with their own fabrication facilities. If the wafer foundries we use are unable or unwilling to manufacture our products in required volumes, or at specified
times, we may have to identify and qualify acceptable additional or alternative foundries. This qualification process could take six months or longer. We may not find sufficient capacity quickly enough, if ever, at an acceptable cost, to satisfy our
production requirements.

Some companies that supply our customers are similarly dependent on a limited number of suppliers to produce
their products. These other companies products may be designed into the same networking equipment into which our products are designed. Our order levels could be reduced materially if these companies are unable to access sufficient production
capacity to produce in volumes demanded by our customers because our customers may be forced to slow down or halt production on the equipment into which our products are designed.

We depend on third parties for assembly and testing of our semiconductor products that could delay and limit our product shipments.

We depend on third parties in Asia for assembly and testing of our semiconductor products. In addition, subcontractors in Asia assemble all of our semiconductor products into a variety of packages. Raw material
shortages, political and social instability, assembly and testing house service disruptions, currency fluctuations, or other circumstances in the region could force us to seek additional or alternative sources of supply, assembly or testing. This
could lead to supply constraints or product delivery delays that, in turn, may result in the loss of revenues. Capacity in the assembly industry has become scarce and lead times have lengthened. This could become more severe, which could in turn
adversely affect our revenues. We have less control over delivery schedules, assembly processes, testing processes, quality assurances, raw material supplies, and costs than competitors that do not outsource these tasks.

Due to the amount of time that it usually takes us to qualify assemblers and testers, we could experience significant delays in product shipments if we
are required to find alternative assemblers or testers for our components. Any problems that we may encounter with the delivery, quality or cost of our products could damage our customer relationships and materially and adversely affect our
results of operations. We are continuing to develop relationships with additional third-party subcontractors to assemble and test our products. However, even if we use these new subcontractors, we will continue to be subject to all of the
risks described above.

Our business is vulnerable to interruption by earthquake, fire, power loss, telecommunications failure, terrorist
activity and other events beyond our control.

We do not have sufficient business interruption insurance to compensate us for actual
losses from interruption of our business that may occur, and any losses or damages incurred by us could have a material adverse effect on our business. We are vulnerable to a major earthquake and other calamities. We have operations in seismically
active regions in British Columbia, Canada and California, and we rely on third-party wafer fabrication and testing facilities in seismically active regions in Asia. We have not undertaken a systematic analysis of the potential consequences to our
business and financial results from a major earthquake in either region. We are unable to predict the effects of any such event, but the effects could be seriously harmful to our business.

Our estimated restructuring accruals may not be adequate.

In 2005, 2006 and 2007, we implemented restructuring plans to streamline production and reduce and reallocate operating costs. In 2001 and 2003, we implemented plans to restructure our operations in response to the decline in demand for our
networking products. We reduced the workforce and consolidated or shut down excess facilities in an effort to bring our expenses into line with our revenue expectations.

While management uses all available information to estimate these restructuring costs, particularly facilities costs, our estimated accruals may prove to be inadequate. If our actual sublease revenues or the results
of our exiting negotiations differ from our assumptions, we may have to record additional charges, which could materially affect our results of operations, financial position and cash flow.

From time to time, we become defendants in legal proceedings about which we are unable to assess our exposure and which could become significant liabilities upon
judgment.

We become defendants in legal proceedings from time to time. Companies in our industry have been subject to claims related
to patent infringement and product liability, as well as contract and personal claims. We may not be able to accurately assess the risk related to these suits, and we may be unable to accurately assess our level of exposure. These proceedings may
result in material charges to our operating results in the future if our exposure is material and if our ability to assess our exposure becomes clearer.

If we cannot protect our proprietary technology, we may not be able to prevent competitors from copying or misappropriating our technology and selling similar products, which would harm our revenues.

To compete effectively, we must protect our intellectual property. We rely on a combination of patents, trademarks, copyrights, trade secret laws,
confidentiality procedures and licensing arrangements to protect our intellectual property rights. We hold numerous patents and have a number of pending patent applications. However some of our patents are expiring in 2010, which could have a
negative affect on our ability to prevent competitors from duplicating certain of our products.

##### Table of Contents

We might not succeed in obtaining patents from any of our pending applications. Even if we are awarded
patents, they may not provide any meaningful protection or commercial advantage to us, as they may not be of sufficient scope or strength, or may not be issued in all countries where our products can be sold. In addition, our competitors may be able
to design around our patents.

To protect our product technology, documentation and other proprietary information, we enter into
confidentiality agreements with our employees, customers, consultants and strategic partners. We require our employees to acknowledge their obligation to maintain confidentiality with respect to PMCs products. Despite these efforts, we cannot
guarantee that these parties will maintain the confidentiality of our proprietary information in the course of future employment or working with other business partners. We develop, manufacture and sell our products in Asia and other countries that
may not protect our products or intellectual property rights to the same extent as the laws of the United States. This makes piracy of our technology and products more likely. Steps we take to protect our proprietary information may not be adequate
to prevent theft of our technology. We may not be able to prevent our competitors from independently developing technologies that are similar to or better than ours.

Our products employ technology that may infringe on the intellectual property and the proprietary rights of third parties, which may expose us to litigation and prevent us from selling our products.

Vigorous protection and pursuit of intellectual property rights or positions characterize the semiconductor industry. This often results in expensive
and lengthy litigation. We, and our customers or suppliers, may be accused of infringing patents or other intellectual property rights owned by third parties in the future. An adverse result in any litigation could force us to pay substantial
damages, stop manufacturing, using and selling the infringing products, spend significant resources to develop non-infringing technology, discontinue using certain processes or obtain licenses to the infringing technology. In addition, we may not be
able to develop non-infringing technology, or find appropriate licenses on reasonable terms or at all.

Patent disputes in the
semiconductor industry are often settled through cross-licensing arrangements. Our portfolio of patents may not have the breadth to enable us to settle an alleged patent infringement claim through a cross-licensing arrangement. We may therefore be
more exposed to third party claims than some of our larger competitors and customers.

The majority of our customers are required to obtain
licenses from and pay royalties to third parties for the sale of systems incorporating our semiconductor devices. Customers may also make claims against us with respect to infringement.

Furthermore, we may initiate claims or litigation against third parties for infringing our proprietary rights or to establish the validity of our
proprietary rights. This could consume significant resources and divert the efforts of our technical and management personnel, regardless of the litigations outcome.

We have significant debt in the form of senior convertible notes.

We have $127 million of 2.25% senior convertible notes outstanding. Our debt could materially and adversely affect our ability to obtain financing for
working capital, acquisitions or other purposes and could make us vulnerable to industry downturns and competitive pressures. Our ability to meet our debt service obligations will be dependent upon our future performance, which will be subject to
financial, business and other factors affecting our operations, many of which are beyond our control. On October 15, 2025, we are obliged to repay the full remaining principal amount of the notes that have not been converted into our common
stock, but we are also subject to certain triggering events that may cause the notes to be repaid earlier.

Securities we issue to fund our operations
could dilute your ownership.

We may decide to raise additional funds through public or private debt or equity financing. If we raise
funds by issuing equity securities, the percentage ownership of current stockholders will be reduced and the new equity securities may have priority rights to your investment. We may not obtain sufficient financing on terms that are favorable to you
or us. We may delay, limit or eliminate some or all of our proposed operations if adequate funds are not available.

Our stock price has been and may
continue to be volatile.

We expect that the price of our common stock will continue to fluctuate significantly, as it has in the past.
In particular, fluctuations in our stock price and our price-to-earnings multiple may have made our stock attractive to momentum, hedge or day-trading investors who often shift funds into and out of stocks rapidly, exacerbating price fluctuations in
either direction particularly when viewed on a quarterly basis.

Securities class action litigation has often been instituted against a
company following periods of volatility and decline in the market price of their securities. If instituted against us, regardless of the outcome, such litigation could result in substantial costs and diversion of our managements attention and
resources and have a material adverse effect on our business, financial condition and operating results. In addition, we could incur substantial punitive and other damages relating to such litigation.

Provisions in Delaware law, our charter documents and our stockholder rights plan may delay or prevent another entity from acquiring us without the consent of our
Board of Directors.

We adopted a stockholder rights plan in 2001, pursuant to which we declared a dividend of one share purchase right
for each outstanding share of common stock. If certain events occur, including if an investor tenders for or acquires more than 15% of our outstanding common stock, stockholders (other than the acquirer) may exercise their rights and receive $650
worth of our common stock in exchange for $325 per right, or we may, at our option, issue one share of common stock in exchange for each right, or we may redeem the rights for $0.001 per right. The issuance of the rights could have the effect of
delaying or preventing a change in control.

In addition, our Board of Directors has the right to issue preferred stock without stockholder approval,
which could be used to dilute the stock ownership of a potential hostile acquirer. Delaware law imposes some restrictions on mergers and other business combinations between us and any holder of 15% or more of our outstanding common stock.

Although we believe these provisions of our charter documents, Delaware law and our stockholder rights plan will provide for an
opportunity to receive a higher bid by requiring potential acquirers to negotiate with our Board of Directors, these provisions apply even if the offer may be considered beneficial by some stockholders.
