EXHIBIT 2

Managements Responsibility for Consolidated Financial Statements

Management of ATI Technologies Inc. is responsible for the integrity of the accompanying consolidated financial statements and all other information in this Annual Report. The
consolidated financial statements have been prepared by Management in accordance with accounting principles generally accepted in Canada. The preparation of the consolidated financial statements necessarily involves the use of estimates and careful
judgment, particularly in those circumstances where transactions affecting a current period are dependent upon future events. All financial information presented in this Annual Report is consistent with the consolidated financial
statements.

To discharge its responsibilities for financial reporting and safeguarding of assets, Management believes that it has established appropriate systems of internal accounting controls
that provide reasonable assurance that the financial records are reliable and form a proper basis for the timely and accurate preparation of financial statements. Consistent with the concept of reasonable assurance, Management recognizes that the
relative cost of maintaining these controls should not exceed their expected benefits. Management further ensures the quality of the financial records through careful selection and training of personnel and the adoption and communication of
financial and other relevant policies.

The Board of Directors discharges its responsibilities with respect to the consolidated financial statements primarily through the activities of its Audit Committee, which is composed
entirely of directors who are not employees of the Company. This committee meets quarterly with Management and with the Companys independent auditors to review the Companys reported financial performance and to discuss audit, internal
control, accounting policy and financial reporting matters. The consolidated financial statements were reviewed by the Audit Committee and approved by the Board of Directors.

The consolidated financial statements have been audited by KPMG LLP, who were appointed by the shareholders at the last Annual General Meeting of Shareholders. Their report is presented
herein.

Auditors Report to the Shareholders

We have audited the consolidated balance sheets of ATI Technologies Inc. as at August 31, 2005 and 2004 and the consolidated statements of operations and retained earnings and cash
flows for each of the years in the three-year period ended August 31, 2005. These financial statements are the responsibility of the Companys management. Our responsibility is to express an opinion on these financial statements based on our
audits.

We conducted our audits in accordance with Canadian generally accepted auditing standards. Those standards require that we plan and perform an audit to obtain reasonable assurance
whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles
used and significant estimates made by management, as well as evaluating the overall financial statement presentation.

In our opinion, these consolidated financial statements present fairly, in all material respects, the financial position of the Company as at August 31, 2005 and 2004 and the results of
its operations and its cash flows for each of the years in the three-year period ended August 31, 2005 in accordance with Canadian generally accepted accounting principles.

# Comments by Auditors
for U.S. Readers on Canada-U.S. Reporting Difference

In the United States, reporting
standards for auditors require the addition of an explanatory paragraph (following the
opinion paragraph) when there is a change in accounting principles that has a material
effect on the comparability of the companys financial statements, such as the change
described in note 1 (o) to the financial statements. Our report to the shareholders dated
October 4, 2005 is expressed in accordance with Canadian reporting standards which do not
require a reference to such changes in accounting principles in the auditors report
when the change is properly accounted for and adequately disclosed in the financial
statements.

|                               |  | Cash and cash equivalents include all highly liquid instruments with a maturity of less than 90 days from
the acquisition date. The carrying amounts of cash and cash equivalents are stated at cost, which
approximates their fair values. The Companys short-term investments include: (i) highly liquid instruments
with a maturity date of 90 days or more but less than one year from the acquisition date that are carried
at cost, which approximates their fair values; (ii) auction rate paper that is carried at cost, which
approximates fair value; (iii) portfolio investments, consisting of actively managed funds holding
government and corporate obligations, agency discount notes, money market funds, commercial paper,
and auction rate paper; and (iv) corporate bonds. Both portfolio investments and corporate bonds are
carried at amortized cost plus accrued interest. The Company regularly reviews the carrying value of its
investments. Should there be a decline in value that is other than a temporary decline, the Company
measures the amount of the write-down based on the quoted market value of the investments and
charges such write-down to the consolidated statements of operations and retained earnings.

| |  | The Company does not amortize goodwill but is required to evaluate goodwill annually or whenever events or changes in circumstances indicate that the carrying amount may not be
recoverable. Impairment is tested at the reporting unit level by comparing the carrying value of the reporting unit in which the goodwill resides to its fair value. The fair values of the reporting units are estimated using a discounted cash flow
approach. To the extent a reporting units carrying amount exceeds its fair value, an impairment of goodwill exists. Impairment is then measured by comparing the fair value of goodwill, determined in a manner similar to a purchase price
allocation, to its carrying amount. During the fourth quarters of fiscal 2005 and 2004, the Company performed its annual goodwill impairment test and determined that there was no goodwill impairment.

| |  | The Company reviews capital and intangible assets for impairment on a regular basis or whenever events or changes in circumstances indicate that the carrying amount may not be
recoverable. Recoverability is assessed by comparing the carrying amount to the projected undiscounted, future net cash flows that the long-lived assets are expected to generate. If the carrying amount exceeds such cash flows, an impairment charge
is recognized equal to the excess of the assets carrying value over their fair value.

| |  | The Company regularly reviews the carrying values of its long-term investments. Should there be a decline in value of the Companys long-term investments that is other than a
temporary decline, the Company measures the amount of the write-down based on the fair value of the shares of the investee and charges such write-down to the consolidated statements of operations and retained earnings.

| |  | Revenue is recognized when evidence of an arrangement exists, risks and rewards of ownership have been transferred to customers, selling price is fixed and determinable and
collectibility is reasonably assured. Sales made to distributors and retailers under agreements allowing for price protection and/or rights of return are recognized at the time of sale to these customers. Estimated returns and allowances, price
protection and sales rebates are recorded as a reduction of revenue at the time of revenue recognition. Estimates are based on historical experience, planned customer incentive programs and other relevant factors. If estimates of future market
conditions and changing product life cycles in the marketplace are inaccurate, it may be necessary to increase customer incentive offerings, which could necessitate a further reduction in revenue. Such increases are recorded as a reduction of
revenue at the time the program is introduced or enhanced. The Company also provides for the estimated cost of product warranties at the time of revenue recognition.
|
| |  | The Company primarily uses a binding purchase order as evidence of its sales arrangements and, in certain cases, uses contractual agreements. The Company considers delivery to occur
upon shipment, provided risk and rewards of ownership, including transfer of title, have passed to the customer. At the point of sale, the Company assesses whether collection is reasonably assured. If the Company determines that collection is not
reasonably assured, the Company defers recognition of the revenue until collection becomes reasonably assured, which is generally upon receipt of cash.

| |  | The Company follows the percentage-of-completion method of accounting for contracts requiring the Company to develop customized technology to meet a customers specifications.
Under such contracts, revenue is recognized based on the ratio of total costs incurred to date to overall estimated costs. Provisions for estimated losses on contracts, if any, are recognized when identified.

| |  | Where estimating the final outcome of a project is impractical, except to ensure that no loss will be incurred, the Company uses a zero estimate of profit until results can be estimated
more precisely. Under this method, the portion of total contract revenue earned to date is determined by measuring total cost incurred. The Company then records an equal amount of revenue against costs. Cost of revenue is adjusted to recognize the

| |  | The Company uses the asset and liability method of accounting for income taxes. Future income tax assets and liabilities are recognized for future income tax consequences attributable
to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, net operating loss carryforwards and undeducted R&D pools. Future income tax assets and liabilities are measured
using enacted or substantively enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect of a change in tax rates is recognized in the year that
includes the substantive enactment date. A valuation allowance is recorded against any future income tax asset if it is more likely than not that the asset will not be realized. Income tax expense or recovery is, primarily, the sum of the
Companys provision for current income taxes and the difference between opening and closing balances of future income tax assets and liabilities.

| |  | Basic net income per share has been calculated by dividing the net income for the year by the weighted average number of common shares outstanding during the year. The Company uses the
treasury stock method for calculating diluted net income per share. Diluted net income per share is computed similar to basic net income per share, except that the weighted average number of common shares outstanding is increased to include
additional shares from the assumed exercise of stock options and equity-settled restricted share units (RSUs), if dilutive. The number of additional shares is calculated by assuming that outstanding stock options and RSUs were exercised
and that the proceeds from such exercises were used to acquire shares of common stock at the average market price during the reporting year.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(CONT.)

Years ended August 31, 2005, 2004 and 2003 (Tabular amounts in thousands of U.S. dollars, except per share amounts)

| |  | On September 1, 2004, the Company adopted the revised CICA Handbook Section 3870, Stock-based Compensation and Other Stock-based Payments, which requires the application of
a fair value method of accounting to all stock-based compensation arrangements with employees. As a result, the Company is required to estimate the fair value of the stock options granted and expense that fair value over the service period which, in
all cases, equals the vesting period of the stock options. Prior to September 1, 2004, the Company recorded no compensation cost on the grant of stock options to employees. In accordance with the transitional provisions of Section 3870, the Company
has retroactively, without restatement, applied the fair value method of accounting for stock option awards granted since September 1, 2002, using the Black-Scholes option pricing model, and recorded an adjustment to opening retained earnings at
September 1, 2004 in the amount of $13.8 million, representing the stock option expense, net of income taxes, for fiscal 2003 and 2004. The offsets to retained earnings are increases in contributed surplus and future income tax assets in the
amounts of $17.5 million and $3.7 million, respectively. The stock option expense for the year ended August 31, 2005 was $34.0 million.

| |  | The Company has RSU and deferred share unit (DSU) plans, which are described in note 12. For equity-settled RSUs, stock-based compensation, representing the underlying value
of the common shares of the Company at the date of grant of the RSUs, is recognized evenly over the three-year vesting period. RSUs and DSUs that will be settled in cash are recorded as liabilities. The measurement of the liability and compensation
costs for these awards is based on the intrinsic value of the award and is recorded as a charge to operating income over the vesting period of the award. Changes in the Companys payment obligation subsequent to grant of the award and prior to
the settlement date, due to changes in the market value of the underlying Company common shares, are recorded as a charge to operating income in the period incurred. The payment amount is established for cash-settled RSUs as of the vesting date of
the award and for DSUs as of the later of the date of termination of employment or directorship.

| |  | The preparation of consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the dates of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting years presented. Significant estimates are used in determining the allowance for doubtful
accounts, provision for inventory obsolescence, useful lives of long-lived assets, goodwill and long-lived asset impairment testing, valuation of long-term investments, realization of future tax assets, and estimates for sales returns and
allowances, price protection and sales rebates. Management makes its estimates based on historical experience and on various other assumptions it believes are reasonable. Actual results could differ from those estimates.

| |  | During fiscal 2004, the Company adopted CICA Accounting Guideline (AcG) No. 13, Hedging Relationships, for its derivative instruments. The Company engages in
activities to purchase certain derivative financial instruments, principally forward foreign exchange contracts, to manage its foreign currency exposures. The Companys policy is not to utilize derivative financial instruments for trading or
speculative purposes.                                                                                                                                                                                                                                                    
|
| |  | The Company formally documents all relationships between hedging instruments and hedged items, as well as the risk management objective and strategy for undertaking various hedge
transactions. This process includes linking all derivatives to specific assets and liabilities on the balance sheet or to specific firm commitments or anticipated transactions. The Company also formally assesses, both at the hedges inception
and on an ongoing basis, whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in fair values or cash flows of hedged items.                                                                        
|
| |  | The Company purchases forward foreign exchange contracts to hedge anticipated Canadian dollar expenses pertaining to its operations in Canada. These instruments are not recognized in
the consolidated financial statements at inception. Foreign exchange gains and losses on these contracts are deferred off-balance sheet and recognized as an adjustment to the operating expenses when the operating expenses are incurred.                                                                                                                                                                                                                                                           
|
| |  | Realized and unrealized gains or losses associated with derivative instruments, which have been terminated prior to the occurrence of the hedge transaction or cease to be effective
prior to maturity, are deferred under other current, or non-current, assets or liabilities on the balance sheet and recognized in income in the period in which the underlying hedged transaction is recognized. In the event a designated hedged item is
sold or extinguished or matures prior to the termination of the related derivative instrument, any realized or unrealized gain or loss on such derivative instrument is recognized in income.

(i)     Generally accepted accounting principles
In July 2003, the CICA issued Handbook Section 1100, Generally Accepted Accounting Principles. This Section establishes standards for financial reporting in accordance with
Canadian GAAP. It describes what constitutes Canadian GAAP and its sources. This section also provides guidance on sources to consult when selecting accounting policies and determining appropriate disclosures when a matter is not dealt with

| |  | In November 2004, the CICA revised AcG No. 15, Consolidation of Variable Interest Entities, to AcG-15R, which provides guidance for determining when an enterprise includes
the assets, liabilities and results of activities of entities that are subject to control on a basis other than ownership of voting interests (a variable interest entity). This guideline is effective for the Companys 2005 fiscal
year. The adoption of this standard did not have an impact on the Companys financial position, results of operations or cash flows.

| |  | In November 2003, the CICA approved amendments to Handbook Section 3860, Financial Instruments  Presentation and Disclosure, to require obligations that may be
settled, at the issuers option, by a variable number of the issuers own equity instruments to be presented as liabilities. Thus, securities issued by an enterprise that give the issuer unrestricted rights to settle the principal amount
in cash or in the equivalent value of its own equity instruments will no longer be presented as equity.                                                                                                                                                                     
|
| |  | The CICA concluded that not all such obligations establish the type of relationship that exists between an entity and its owners, but rather they convey more of a debtor/creditor
relationship because they require the issuer to convey a fixed amount of value to the holder that does not vary with changes in the fair value of the issuers equity instruments. Therefore, these instruments should be presented as
liabilities.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(CONT.)

Years ended August 31, 2005, 2004 and 2003 (Tabular amounts in thousands of U.S. dollars, except per share amounts)



|                             |  | The standard will be effective for the Companys 2006 fiscal year. The Company expects that the adoption of this standard will have no material impact on its financial position,
results of operations or cash flows.

Financial Instruments
In January 2005, the CICA issued Section 3855, Financial Instruments  Recognition and Measurement, Section 1530, Comprehensive Income and Section 3865,
Hedges. The new standards will be effective for interim and annual financial statements commencing in the Companys 2007 fiscal year. Earlier adoption is permitted. Most significantly for the Company, the new standards will require
presentation of a separate statement of comprehensive income. Foreign exchange gains and losses on the translation of the financial statements of self-sustaining subsidiaries previously recorded in a separate section of shareholders equity
will be presented in comprehensive income. Derivative financial instruments will be recorded in the balance sheet at fair value and the changes in fair value of derivatives designated as cash flow hedges will be reported in comprehensive income. The
existing hedging principles of AcG-13 will be maintained. The Company is assessing the impact of the new standards.

|NOTE 2.Financial instruments |  | Financial instruments, which potentially subject the Company to concentrations of credit risk, consist
primarily of cash and cash equivalents, short-term investments, accounts receivable and sundry
receivables. The Company invests only in high-quality cash and cash equivalents and short-term
investments. A majority of the Companys accounts receivable is derived from sales to original
equipment manufacturers, add-in-board manufacturers, original design manufacturers, distributors and
retailers in the personal computer, cellular phone and digital television industries. The Company performs
ongoing credit evaluations of its customers financial condition and limits the amount of credit extended
when deemed necessary. In addition, a significant portion of the total accounts receivable is insured
against possible losses. The Company maintains adequate reserves for potential credit losses as
estimated by management.                                                                                                                                               
|                            
|                             |  | The joint venture Commerce Valley Realty Holdings Inc. (CVRH), in which the Company has a 50.0%
ownership, entered into an interest rate swap contract in fiscal 2001 to hedge its exposure to the
interest rate risk applicable to its mortgage for a building facility in Markham, Ontario. This interest rate
swap contract closed on September 10, 2002, resulting in a proportionate loss of $1.4 million to the
Company. The loss is treated as a deferred expense item in the consolidated balance sheets and is
charged to the consolidated statements of operations and retained earnings as a yield adjustment to
the interest expense over the term of the mortgage (note 19).                                                                                                                                                                                                                                                                                                                                                                                                                
|                            
|                             |  | The carrying amounts of cash equivalents, short-term investments, accounts receivable, sundry
receivables, accounts payable and accrued liabilities approximate their fair market values because of the
short-term nature of these instruments.

|                             |  | The fair values of the obligation under capital lease and mortgage payable approximate their carrying values.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
|                            
|                             |  | The financial condition, operating results and cash flows of the Company may be materially and adversely
impacted by a substantial weakening of the U.S. dollar against local currencies as the Companys long-term
debt and a significant amount of its operating expenses are paid in local currencies other than the
U.S. dollar.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
|                            
|                             |  | The Company enters into forward foreign exchange contracts (Forwards) to hedge its foreign currency
exposure on expenses incurred for its Canadian operations. The Forwards obligate the Company to sell
U.S. dollars for Canadian dollars in the future at predetermined exchange rates and are matched with
anticipated future operating expenses in Canada. The Forwards do not subject the Company to risk from
exchange rate movements because gains and losses on such contracts offset losses and gains on
exposures being hedged. The counterparties to the Forwards are multinational commercial banks and,
therefore, the credit risk of counterparty non-performance is low.

| | In
March 2005, the Board of Directors authorized a share repurchase program of up to 24.7
million common shares through a normal course issuer bid. In fiscal 2005, the Company
repurchased and cancelled a total of two million shares for an aggregate cost of $23.9
million. If considered advisable, additional shares may be repurchased from time to time
on the open market through March 29, 2006 at prevailing market prices. The timing and
amount of purchases, if any, will be dependent upon the availability and alternative uses
of capital, market conditions and other factors.

| | (b)    Preferred sharesAn unlimited number of preferred shares, ranking in priority upon
distribution of assets over common shares, may be issued in series with additional
provisions as fixed by the Board of Directors.
| | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | No
preferred shares have been issued to date.

| | (c)     Common
share option plans
(i)     The
Company maintains a share option plan (the ATI Plan) for the benefit of
management directors,
officers and employees. The ATI Plan, as amended, provides that the aggregate number of
common shares available for issuance pursuant to options granted under the ATI Plan and
all other share compensation arrangements is limited to 47,000,000 common shares. In
general, the maximum number of common shares reserved for issuance in respect of any one
individual may not exceed 5.0%, or in respect of insiders of the Company, may not exceed
10.0%, of the number of common shares issued and outstanding.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(CONT.)

Years ended August 31, 2005, 2004 and 2003 (Tabular amounts in thousands of U.S. dollars, except per share amounts)

| | Options
are granted under the ATI Plan at the discretion of the Board of Directors at exercise
prices determined as the weighted average of the trading prices of the Companys
common shares on The Toronto Stock Exchange or NASDAQ for the five trading days preceding
the effective date of the grant. In general, options granted under the ATI Plan vest over
a period of up to four years from the grant date and expire by no later than the seventh
anniversary of the date of grant.
| | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | Commencing
the third quarter of fiscal 2005, the Company amended the ATI Plan to provide the Board
of Directors with the discretion to award tandem stock appreciation rights (tandem
SARs) in connection with all or a portion of the existing and future options
granted under the ATI Plan. Tandem SARs provide an optionee with the right to surrender
vested options for termination in return for common shares with a market value equal to
the net proceeds that the optionee would have otherwise received had such optionee
exercised the vested options and immediately sold the underlying shares. During the year
ended August 31, 2005, tandem SARs were attached to new option grants only. Options
subject to tandem SARs numbered 3,169,015 at August 31, 2005.
| | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | (ii)    
When the Company acquired ArtX, on April 4, 2000, it assumed the ArtX common shares
options plan (the ArtX Plan). No new options have been issued under this plan
since the date of acquisition. The Company maintains the ArtX Plan for the benefit of
former directors, officers, employees and consultants of ArtX.
| | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | (iii)    
Under an incentive plan entered into in June 2002, the Company provided certain employees
with a performance incentive, consisting of a combination of cash and options, the
receipt of which was conditional upon the Company entering into a specified business
arrangement with a third party by April 2003, later extended to July 28, 2003. The cash
portion of the incentive consisted of three equal payments of $2.7 million, with each
payment to be made upon achievement of specified milestones under the arrangement with
the third party. Under the plan, the employees were also granted options to purchase 2.6
million common shares at an exercise price of $6.96 per share. The options vest 25.0% on
the first anniversary of the grant date and, thereafter, at 6.25% per quarter and are
only exercisable in the event the Company is successful in entering into the
aforementioned arrangement. In February 2003, the Company successfully entered into the
business arrangement with the third party and all the conditions under the plan were
determined to have been met in July 2003. As a result, the first payment of the cash
portion of the incentive, in the amount of $2.7 million, was paid and included as
compensation expense during 2003. The remaining two payments aggregating $5.4 million
were accrued at August 31, 2003 and have been amortized over 18 months. During fiscal
2005, the amount recorded as compensation expense was $1.9 million (2004  $3.5
million).

| | (d)     Restricted share units
In October 2003, the Company adopted three plans to grant RSUs as part of its overall
 stock-based compensation plan. The RSU Plans allow participants to earn actual shares (or, for
non-North American participants, the cash equivalent) of the Company over time, rather than options that
 give employees the right to purchase stock at a set price.



The RSU Plans include: a plan for Canadian employees and
 directors; a plan for U.S. employees and directors; and a plan for all other
employees and directors outside of North America.
In accordance with the terms of the RSU Plans, the Board of Directors approves which
employees and directors are entitled to participate in the respective plans and the
 number of RSUs to be awarded. Each RSU awarded conditionally entitles the
participant to the delivery of one common share (or cash in lieu of such share for participants
 resident outside of North America) upon attainment of the RSU vesting period. RSUs awarded to
 participants vest in accordance with terms determined by
the Board of Directors, which terms may include certain performance criteria in which
 the number of common shares (or cash in lieu of such common shares for participants resident
 outside of North America) to be delivered to a
participant in respect of each RSU awarded is dependent upon the Companys performance and/or market price of the common shares, as determined by the Board of Directors. At the
time that RSUs are granted to participants in North America, the Board of Directors must determine whether the common shares to be delivered to participants upon the vesting of such RSUs will be purchased on the open market, issued from treasury or
obtained from a combination of market purchases and treasury issuances. For participants outside of North America, if common shares are not issued from treasury, they are only entitled to receive a cash payment from the Company equal to the number
of RSUs awarded to such participants multiplied by the value of the common shares on the NASDAQ Stock Market at the relevant vesting date. Each common share issued from treasury upon the vesting of such RSUs reduces the number of common shares
available for issuance under the RSU plans. A total of three million common shares have been reserved for issuance from treasury under the RSU plans. RSUs that are satisfied through the purchase of common shares on the market vest over a maximum
period ending December 31 of the third calendar year after the date of grant. Grants of RSUs to participants residing outside of North America are recognized at their face value, whereby the value of the RSUs and their related amortization are
adjusted based on the underlying value of the Companys common shares at the end of each fiscal quarter.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(CONT.)

Years ended August 31, 2005, 2004 and 2003 (Tabular amounts in thousands of U.S. dollars,
except per share amounts)



| | During fiscal 2004, the Company granted a total of 1,556,244 RSUs to certain employees to replace the annual grant of options for the 2003 calendar year. The Company advanced $22.1
million to the trustee of the RSU plans to enable the trustee to purchase the Companys common shares in the open market for future delivery of such shares to the participants on the vesting dates of the RSUs. The cost of the purchase of these
shares is classified as treasury stock and presented as a reduction of shareholders equity in the Companys consolidated balance sheets. In addition, the Company also awarded a onetime cash payment of $7.8 million to the non-executive
employees who were eligible to participate in the RSU plans. The full amount of the cash payment was expensed
in fiscal 2004. Of the RSUs granted, 42,327 were forfeited during fiscal 2004.

| | In fiscal 2005, 508,803 RSUs vested and were settled by delivery of common shares of the Company to the participants or by cash equivalent to their market value on the vesting date. At
August 31, 2005, 983,033 common shares of the Company were held by the trustee.
| | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | During fiscal 2005, the Company started granting RSUs to its employees which are settled through the issuance of common shares of the Company from treasury. The number of RSUs granted
in fiscal 2005 was 1,183,488 and the number of RSUs forfeited was 57,084. Of the RSUs granted in fiscal 2005, 1,084,723 are subject to performance-related factors which result in the number of common shares that may be issued upon the settlement of
such RSUs at each vesting date being dependent on the Company achieving certain performance targets. As at August 31, 2005,
 there were 2,131,518 RSUs awarded and outstanding.

During fiscal 2004, the Company established a plan to grant DSUs to its non-management directors. This plan was retroactively applied and 51,457 DSUs were granted for service related to
fiscal 2003. Under this plan, the directors will receive DSUs, in addition to cash payments, as part of their annual compensation package. A DSU is a unit equivalent in value to one common share of the Company based on the five-day average trading
price of the Companys common shares on NASDAQ (the Weighted Average Price) immediately prior to the date on which the value of the DSU is determined. DSUs vest quarterly over a period of one year and may not be redeemed until the
director leaves the board, thereby providing an ongoing equity stake in the Company throughout the directors period of service. On termination or retirement from the Board, directors will be able to redeem DSUs during the six-month period
following their departure from the Board. DSUs, however, must be redeemed prior to the end of the year following departure from the Board, based on the Weighted Average Price at the time of redemption. Alternatively, a director may elect to receive
RSUs in lieu of DSUs provided the market value of his holdings in the Companys common stock equity is greater than $350,000. DSUs granted during fiscal 2005 numbered 40,625 (2004  40,625). As at August 31, 2005, there were 132,707
DSUs outstanding, of which 109,009 were vested.

As of the date of the grant, the fair values of the DSUs outstanding, being the fair market value of the Companys common shares at that date, are recorded as a liability on the
Companys consolidated balance sheet and are amortized over the one-year vesting period of the DSU. The value of the DSU liability is adjusted to reflect changes in the market value of the Companys common shares. The expense for fiscal
2005 related to DSUs granted to the directors for services rendered was $0.2 million (2004  $1.2 million).(f)   Contributed surplus

During fiscal 2005, a net total of $51.1 million was added to contributed surplus, of which $17.5 million related to the change in accounting for stock-based compensation (note
1(o)), $34.0 million and $8.1 million related to the amortization of stock option expense and RSU expense, respectively, and $0.4 million related to the tax effect on the stock option expense. The above increase was partly offset by
$7.2 million worth of RSUs granted to employees that were exchanged for common shares upon vesting of the RSUs and $1.7 million pertaining to the amortization of stock option expense being reclassified to the share capital account as the
related options were exercised during 2005.


During 2004, a total of $5.8 million was added to contributed surplus relating to the
 amortization of RSU expenses for the employees residing in North America.

filed in May 2001 in the United States District Court for the Eastern District of Pennsylvania for a cash payment of $8.0 million. This litigation related to alleged misrepresentations and omissions made by the Company and certain directors and
officers during a period preceding its May 2000 earnings warning. The terms of the Stipulation and Agreement of Settlement received final Court approval on April 28, 2003 and included no admission of liability or wrongdoing by the Company or other
defendants. During fiscal 2003, the Company received $3.3 million from its insurer as its contribution
towards the settlement.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(CONT.)

Years ended August 31, 2005, 2004 and 2003 (Tabular amounts in thousands of
 U.S. dollars, except per share amounts)

| | (b)   Regulatory matters
On January 16, 2003, the staff of the Ontario Securities Commission (the OSC) filed a notice of hearing and statement of allegations (the Notice). The Notice
alleged that the Company failed to disclose information concerning the shortfall in revenues and earnings that occurred in the third quarter of fiscal 2000, as required by the listing rules of The Toronto Stock Exchange. The Notice also alleged that
the Company made a misleading statement to the staff of the OSC in August 2000 regarding the events leading up to the disclosure on May 24, 2000 of the shortfall. Seven individuals were named in the Notice. The Notice alleged that six of these
individuals, including K.Y. Ho, the Chairman and then Chief Executive Officer of the Company, engaged in insider trading contrary to the Securities Act (Ontario). On March 29, 2005, a panel of the OSC approved a settlement agreement reached between
the Company and OSC staff. As part of the settlement, the Company agreed to pay Cdn. $900,000 in costs and settlement payments and agreed to provide a letter of comfort confirming its practices and procedures related to trading and corporate
governance. The individuals named in the Notice, other than Mr. Ho and his wife, also entered into settlement agreements with the OSC. In October 2005, a panel of three commissioners of the OSC (including the Vice-Chair of the OSC) dismissed all
allegations of insider trading against K.Y. Ho and his wife. The panels decision completely exonerated
Mr. Ho and his wife. The decision was made following a hearing which was held by the OSC panel in the spring
of 2005.

| | (i)    During the second quarter of fiscal 2003, the Company announced the closure of ATI Technologies (Europe) Limited (ATEL), its subsidiary in Dublin, Ireland, and recorded
a pre-tax charge of $2.8 million. The charge included a $1.4 million write-down of ATELs building facility to estimated fair value less cost to sell. The Company completed the major components of the exit plan for ATEL in July
2003.
During fiscal 2004, the Company was able to sell ATELs building facility at a higher price than originally estimated, resulting in a recovery of $0.5 million from the
restructuring charge. The Company also paid out the remaining cash portion of the restructuring charge of
 $0.5 million during fiscal 2004.
| | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | (ii)    During the fourth quarter of fiscal 2003, the Company decided to close the operations of ATI Research GmbH, its FireGL product division located in Starnberg, Germany, in order to
consolidate its research and development activities. As a result, the Company recorded a pre-tax charge
of $3.8 million for the quarter pertaining to the closure of ATI Research GmbH.
During fiscal 2004, the Company recovered $0.2 million related to the
 restructuring charge of ATI Research GmbH.
During fiscal 2004, the Company made a cash payment of $3.5 million relating to the pre-tax charge recorded in fiscal 2003. The Company completed the major components of its exit
plan for ATI Research GmbH in December 2003. During fiscal 2005, the Company paid off the remaining
balance of $18,000 relating to the restructuring liabilities accrual.

| | (d)    Lease exit charge (recovery)
During the second quarter of fiscal 2003, the Company determined that it would exit the two leased properties located in Markham, Ontario. As a result, the Company recognized the fair
value of the future net costs related to the leases in the amount of $2.4 million as a charge in the second
quarter.
During the fourth quarter of fiscal 2003, the Company recorded an additional charge of $0.3 million related to the exit costs of the above-mentioned lease properties due to a change
in estimate of the fair value of the future net costs.

|                              |  |            |  | During fiscal 2004, the Company determined that it would re-occupy the two leased properties, due to
an expansion of business. This resulted in a reduction of the previously accrued exit charge liability in
the amount of $1.5 million.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               |  |            |  |            |  |            |  |            |  |          |  |          |  |

Subsequent to the fiscal 2003 year-end, the Company and Cirrus Logic, Inc. (Cirrus) announced that
they had entered into a cross-license agreement and had settled all outstanding litigation between the
companies related to certain patent infringement lawsuits.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    |  |            |  |            |  |            |  |

PC products division, a business that Cirrus exited several years ago, for a cash payment of $9.0 million
from the Company.                                                                                                                                                                                                                                                                                                                                                                                                                                                         |  |            |  |            |  |            |  |            |  |          |  |          |  |

|NOTE 17.Segmented information |  |            |  | The Company designs and manufactures innovative 3D graphics and digital media silicon solutions.
The Company determined in the first quarter of fiscal 2005 that it operates in two reportable segments:
Personal Computer (PC) and Consumer. The PC segment includes all 3D graphics, video and multimedia
products and chipsets which are developed for use in desktop and notebook personal computers including
professional workstations, servers and home media PCs. The Consumer segment includes products
used in mobile phones, PDAs, DTVs and set-top boxes. The Consumer segment also includes royalties
and contract engineering services derived from mobile phone and game console products. Previously,
the Company reported as a single reportable segment. Fiscal 2004 and 2003 amounts have been
presented below based on the reportable segments identified in 2005.
|                              |  |            |  | The Companys management evaluates segment performance based on revenue and on operating
income (loss) which is calculated as income (loss) from operations before taxes, excluding expenses
related to stock-based compensation, amortization of intangible assets and other charges.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   |  |

inter-segment revenues. The accounting policies for all operating segments are the same as those
described in the summary of significant accounting policies.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    |  |            |  |            |  |            |  |

the interest rate risk applicable to its expected future mortgage requirement. This contract was a forward
start pay fixed derivative agreement for a notional amount of Cdn. $38.0 million. The agreement provided
for the joint venture to pay a fixed rate of 6.42% in exchange for a floating rate equivalent to one-month
Canadian bankers acceptances. The Company and the other joint venture partners are guarantors of the
credit facility. This interest rate swap contract closed on September 10, 2002, resulting in a proportionate
loss of $1.4 million to the Company. The loss was charged to the consolidated statements of operations
and retained earnings as a yield adjustment to the interest expense over the term of the mortgage.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(CONT.)

Years ended August 31, 2005, 2004 and 2003 (Tabular amounts in thousands
of U.S. dollars, except per share amounts)

| | (i)   Under Canadian GAAP, purchased in-process R&D is capitalized and amortized over its estimated useful life. Asset recoverability is reviewed on an ongoing basis. Under U.S. GAAP,
purchased in-process R&D is written off at the time of acquisition.
| | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | (ii)   Under Canadian GAAP, effective September 1, 2004, the Company adopted the fair value method of recognizing stock-based compensation. For U.S. GAAP purposes, the intrinsic value
method is used to account for stock-based compensation for employees. Compensation expense of $34.0 million (note 12(c)) recognized under Canadian GAAP would not be recognized under U.S. GAAP for the year ended August 31, 2005. In addition, the
retroactive adoption of the policy described in note 1(o)(i) would not be recognized. The exercise price of stock options is equal to the market value of the underlying shares at the date of grant; therefore, except as indicated below, there is no
expense under the intrinsic method for U.S. GAAP purposes for fiscal 2005.
As described in note 12(c)(i), the Company granted tandem SARs. These awards have been accounted for using the fair value method under Canadian GAAP. For U.S. GAAP purposes, variable
plan accounting under the intrinsic method is used to account for tandem SARs. Under variable plan accounting, compensation expense is adjusted to reflect increases in the market value of the Companys common shares to the measurement date.
There is no compensation expense under U.S. GAAP for the tandem SARs in fiscal 2005,
 as the exercise price for the awards exceeds the market price at year-end.
| | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | (iii)   Under U.S. GAAP, options granted after January 18, 2001, with an exercise price denominated in a currency other than the currency of the primary economic environment of either the
employer or the employee, are required to be accounted for under the variable plan method. During the period from January 19, 2001 to February 28, 2002, certain options were granted with exercise prices in Canadian dollars. Under Canadian GAAP,
there is no equivalent requirement. There were no such options granted after February 28, 2002.
| | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | (iv)   Under U.S. GAAP, the intrinsic value of the stock options issued under the incentive plan entered into in June 2002 (note 12(c)(iii)) is calculated as the increase in the
Companys stock price between the grant date and the date on which all the conditions of the specified business arrangement were determined to have been met. The compensation expense is recognized over the vesting period of the options. Under
Canadian GAAP, there is no equivalent requirement.
| | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | (v) Under Canadian GAAP, loss on a hedging transaction is allowed to be amortized over the term of the mortgage. Under U.S. GAAP, loss on a hedging transaction is written off when the
hedge is determined to be ineffective.
| | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | (vi)   The Company accounts for its share options under the provisions of the Accounting Principles Board Opinion No. 25, Accounting for Stock Issued to Employees (APB
25), and related interpretations. Accordingly, for U.S. GAAP purposes, compensation expense for its share option plans, based on the intrinsic value, has been recorded in the reconciliation above for all periods presented. For U.S. GAAP
purposes, had compensation expense for the Companys share option plans been determined based on the fair value at the grant dates for awards under the plans consistent with the method prescribed under Financial Accounting Standards Board
(FASB) Statement of Financial Accounting Standards (SFAS) No. 123, Accounting for Stock-based Compensation, the Companys net income and net income per share would have been reported as the pro forma amounts indicated in the table below:

weighted average estimated fair values at the date of the grant, as defined by SFAS No.

and $2.65 per share option, respectively.    The fair value of each

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(CONT.)

Years ended August 31, 2005, 2004 and 2003 (Tabular amounts in thousands of U.S. dollars, except per share amounts)

| | (i) Canadian GAAP requires the proportionate consolidation of interests in joint ventures. Proportionate consolidation is not permitted under U.S. GAAP and interests in joint ventures
are accounted for in accordance with the equity basis of accounting.
| | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | Although the adoption of proportionate consolidation has no impact on net income or shareholders equity, it does increase assets, liabilities, revenue, expenses and cash flows
from operations from those amounts otherwise reported under U.S. GAAP. As allowed for under the rules of the Securities and Exchange Commission, this difference has not been reflected in the table of certain consolidated balance sheet items
presented above.
| | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | (ii) Additional disclosures as required in accordance with U.S. GAAP:
| | ---------------------------------------------------------------------

| | (A) As at August 31, 2005, the consolidated accounts receivable provision for returns and doubtful accounts was approximately $22.4 million (2004  $17.1
million).
| | -------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | (B) As at August 31, 2005, sales rebates payable represent 24.8% of total consolidated current liabilities (2004  22.0%) .
| | ---------------------------------------------------------------------------------------------------------------------------

| | (C) For the year ended August 31, 2005, the net foreign exchange gain was approximately $1.2 million (2004  gain of $0.5 million; 2003  gain of $0.8
million).
| | ----------------------------------------------------------------------------------------------------------------------------------------------------------------

| | (D) For the year ended August 31, 2005, the advertising costs incurred by the Company were approximately $27.5 million (2004  $22.5 million; 2003  $14.0
million).
| | --------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | (iii) Comprehensive income:
| | ---------------------------

| | SFAS No. 130, Reporting Comprehensive Income, requires disclosure of comprehensive income, which includes reported net income adjusted for other comprehensive income. Other
comprehensive income is defined as the change in equity of a business enterprise during a period from transactions and other events and circumstances from non-owner sources. The following table presents comprehensive income and its
components:
| | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| |                                         |  | 2005    |  | 2004     |  | 2003    | 
| | --------------------------------------- |  | ------- |  | -------- |  | ------- | 
| |                                        
| | Net income in accordance with U.S. GAAP |  | $41,676 |  | $188,041 |  | $12,171 | 
| | Other comprehensive income:             | 
| | Unrealized gain on forward              | 
| | foreign exchange contracts(1)           |  | 3,393   |  | 1,276    |  |        | 
| |                                        
| | Comprehensive income                    |  | $45,069 |  | $189,317 |  | $12,171 | 
| |                                        

| | (1) As at August 31, 2005, the Company had Cdn. $94.5 million (2004  Cdn. $35.0 million) outstanding in forward exchange contracts that mature in the next six months at an
average exchange rate of 1.2579. All of the forward foreign exchange contracts have become favorable to the Company since their inception and have an unrealized fair value of $4.7 million at August 31, 2005 (2004  $1.3
million).
| | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | (iv) Operating, financing and investing cash flows presented on the consolidated statement of cash flows under Canadian GAAP would not differ from amounts disclosed in a consolidated cash flow statement prepared under U.S. GAAP.
| | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | (v) Under Canadian GAAP, the aggregate purchase price of ArtX was based on the average closing market price of the Companys common shares around the closing date of the
transaction. Under U.S. GAAP, the aggregate purchase price of ArtX was based on the average closing market price of the Companys common shares around the date of the announcement of the transactions. As a result, the recorded amount of
goodwill and related amount of accumulated amortization differ.
| | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | (c)    New United States accounting pronouncements
| | --------------------------------------------------

| | In December 2004, the FASB issued SFAS No. 123R, Share-Based Payment. SFAS No. 123R requires employee stock options and rights to purchase shares under stock participation
plans to be accounted for under the fair value method, and eliminates the ability to account for these instruments under the intrinsic value method prescribed by APB Opinion No. 25, as allowed under the original provisions of SFAS No. 123. SFAS No.
123R requires the use of an option pricing model for estimating fair value, which is amortized to expense over the service periods. The requirements of SFAS No. 123R are
effective for the first fiscal year beginning after June 15, 2005. SFAS No. 123R allows
for either prospective recognition of compensation expense or retrospective recognition,
which may be back to the original issuance of SFAS No. 123. The Company is currently
evaluating the impact of the adoption of SFAS No. 123R.

| | In
March 2005, the SEC staff issued guidance on SFAS No. 123R. Staff Accounting Bulletin No.
107 (SAB 107) was issued to assist preparers by simplifying some of the
implementation challenges of SFAS No. 123R while enhancing the information that investors
receive. SAB 107 creates a framework that is premised on two overarching themes: (i)
considerable judgment will be required by preparers to successfully implement SFAS No.
123R, specifically when valuing employee stock options; and (ii) reasonable individuals,
acting in good faith, may conclude differently on the fair value of employee stock
options. Key topics covered by SAB 107 include: (a) valuation models  SAB 107
reinforces the flexibility allowed by SFAS No. 123R to choose an option pricing model
that meets the standards fair value measurement objective; (b) expected volatility
 SAB 107 provides guidance on when it would be appropriate to rely exclusively on
either historical or implied volatility in estimating expected volatility; and (c)
expected term  the new guidance includes examples and some simplified approaches to
determining the expected term under certain circumstances. The Company will apply the
principles of SAB 107 in conjunction with its adoption of SFAS No. 123R.
| | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | In
November 2004, the FASB issued SFAS No. 151, Inventory Costs, an amendment of APB No. 43,
Chapter 4. SFAS No. 151 amends APB No. 43, Chapter 4, to clarify that abnormal amounts of
idle facility expense, freight, handling costs and wasted material (spoilage) should be
recognized as current period charges. In addition, SFAS No. 151 requires that allocation
of fixed production overhead to the cost of conversion be based on the normal capacity of
the production facilities. The provision of SFAS No. 151 shall be effective for inventory
costs incurred during fiscal years beginning after June 15, 2005. The Company does not
expect the adoption of SFAS No. 151 to have a material impact on its consolidated
financial statements.
| | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | In
December 2004, the FASB issued SFAS No. 153, Exchanges of Non-monetary Assets  An
Amendment of APB Opinion No. 29 (APB No. 29), Accounting for Non-monetary
Transactions. SFAS No. 153 eliminates the exception from fair value measurement for
non-monetary exchanges of similar productive assets in paragraph 21(b) of APB No. 29 and
replaces it with an exception for exchanges that do not have commercial substance. SFAS
No. 153 specifies that a non-monetary exchange has commercial substance if the future
cash flows of the entity are expected to change significantly as a result of the
exchange. SFAS No. 153 is effective for fiscal periods beginning after June 15, 2005. The
Company does not expect the adoption of SFAS No. 153 to have a material impact on its
consolidated financial statements.
| | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | In
June 2005, the FASB issued SFAS No. 154, Accounting Changes and Error Corrections, a
replacement of APB Opinion No. 20, Accounting Changes, and FASB No. 3, Reporting
Accounting Changes in Interim Financial Statements. The statement applies to all
voluntary changes in accounting principle and changes the requirements for accounting for
and reporting of a change in accounting principle. SFAS No. 154 requires retrospective
application to prior periods consolidated financial statements of a voluntary
change in accounting principle unless to do so is impracticable. It is effective for
accounting changes and corrections of errors made in fiscal years beginning after
December 15, 2005. Earlier application is permitted for accounting changes and
corrections of errors made occurring in fiscal years beginning after June 1, 2005. The
Company does not expect the effect of SFAS No. 154 to have a material impact on its
consolidated financial statements.

|NOTE 22. |  | (a)  American Video Graphics LLP
|-------- |  | --------------------------------

|Litigation |  | American Video Graphics LLP filed
a series of suits in the Eastern District of Texas alleging infringement of several patents against
various PC manufacturers, game console
manufacturers and videogame publishers. After some reconfiguration of the suits, there are a total
of six suits pending. Of these six suits, there are two suits pending against the entire group of PC
manufacturers and two suits pending against the
entire group of game console manufacturers. The Company voluntarily intervened in these four suits.
The Company participated in two district court-ordered mediations for these matters. Neither mediation
resulted in settlement. The first trial
involving the PC manufacturers is currently scheduled for September 2006 and the first trial involving
the game console manufacturers is scheduled for December 2006.

| |  | (b)  U.S. securities class action lawsuits
| |  | ------------------------------------------

| |  | In August and September 2005, five class action lawsuits
were filed in the United States District Court for the Eastern District of Pennsylvania against the Company and certain of its
directors and officers on behalf of shareholders who purchased the Companys common shares between October 7, 2004 and on or
about June 23, 2005. The claims allege that the Company and certain of its directors and officers violated U.S.
securities laws by failing to disclose material facts and making statements that contained misrepresentations about the
Companys business and future outlook. It is alleged that as a result of the failure to disclose material facts and the
alleged misrepresentations, the Companys stock traded at artificially inflated prices until the stock price dropped
on the news of the Companys third quarter results in June 2005. The claims further allege that, while in possession of
material undisclosed information, certain directors and officers sold a portion of their common shares at inflated prices.
These claims are at a very preliminary stage.
| |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| |  | (c)  U.S. shareholder complaint
| |  | -------------------------------

| |  | In August 2005, a shareholder complaint was filed in the Superior Court of the State of California for the County of Santa Clara by a shareholder on behalf of the Company. The
defendants to the complaint include the Company, members of the Board of Directors and certain officers. The complaint alleges breach of California Law, including breaches of fiduciary duties, abuse of control, gross mismanagement, waste of
corporate assets, unjust enrichment and violation of the California Corporations Code during the period between October 2004 and August 26, 2005. The Company has been served with the complaint. This complaint is at a very preliminary
stage.
| |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | The
Company currently believes the amount of ultimate liability, if any, with respect to
these legal proceedings, including the class action lawsuits and the shareholder
complaint, will not materially affect its financial position, results of operations, or
liquidity. The Company and the named directors and officers intend to defend themselves
vigorously. However, the ultimate outcome of any litigation is uncertain and should any
of these actions or proceedings against the Company be successful, the Company may be
subject to significant damages awards, which could have a material adverse effect on its
financial condition.
