                  ATI Reports Second Quarter Financial Results
                New products generate broad-based customer demand

Markham, Ontario -- March 21, 2003 -- ATI Technologies Inc. (TSX: ATY, NASDAQ:
ATYT), a world leader in the design and manufacture of innovative 3D graphics
and digital media silicon solutions, today announced its financial results for
the second quarter of its 2003 fiscal year, which ended February 28, 2003.

Revenues for the second quarter were $318.5(1) million compared to $322.0
million in the first quarter of fiscal 2003. Gross margin was 28.9 per cent,
rising 1.6 percentage points from 27.3 per cent in the first quarter. Operating
expenses, excluding amortization of intangible assets and other charges(2),
increased $0.7 million to $80.3 million compared to the first quarter.

The net loss for the second quarter was $8.3 million or $0.04 per share compared
to net income of $5.0 million or $0.02 per share for the first quarter of 2003
and a net loss of $3.0 million or $0.01 per share for the same period a year
ago. Adjusted net income(3) for the second quarter was $9.7 million or $0.04 per
share compared to $7.0 million or $0.03 per share for the previous quarter, and
$17.6 million or $0.07 per share for the same period a year ago.

(1)All dollar amounts are stated in U.S. dollars unless otherwise noted. All per
share amounts are stated on a fully diluted basis unless otherwise noted.

(2) The Company incurred other charges during the quarter that are not
considered to be part of the Company's normalized ongoing operations and in
aggregate represent $16.0 million. These charges include costs relating to the
settlement of the U.S. class action lawsuit; costs incurred in connection with
the work of the independent Special Committee of the Board relating to the
Ontario Securities Commission investigation and Notice of Hearing; costs related
to the closure of the European manufacturing operations and lease termination
charges related to surplus space in leased buildings. (See Note 7 to the
consolidated financial statements.)

(3)Adjusted net income excludes the after-tax effect of gain on investments,
after-tax effect of other charges described in Note 7 to the consolidated
financial statements, amortization of goodwill and intangible assets related to
the Company's acquisitions, and deferred tax recovery of future tax liability
pertaining to intangible assets acquired, related to the Company's acquisitions.
Each of these items has been excluded from adjusted net income as they are not
considered to be part of the Company's normalized ongoing operations. While the
Company recognizes that adjusted net income does not have any standardized
meaning described by generally accepted accounting principles, or GAAP, and that
its adjusted net income calculation cannot be used as a comparison to other
companies' financial performance, ATI believes that its adjusted net income more
appropriately reflects the Company's operating performance. Please see the table
titled "Adjusted Net Income - Reconciliation" in Management's Discussion and
Analysis of Interim Financial Results in this release for the reconciliation
between adjusted net income and net income which is determined in accordance
with GAAP.




                                                                         4 of 26

"Customer demand for ATI's new products continued to build during the second
quarter - a quarter that typically sees a seasonal pullback in the marketplace,"
said K.Y. Ho, Chairman and Chief Executive Officer, ATI Technologies Inc. "Our
RADEON(TM) 9700 and RADEON(TM) IGP families of products continued to capture
design wins and gain broad customer acceptance during the quarter. With ATI
shipping its one millionth RADEON(TM) 9700-based chip in the second quarter,
this has unquestionably been the best new product in our industry - ever."

"With the release of our RADEON(TM) 9800 PRO, RADEON(TM) 9600 and RADEON(TM)
9200 for the desktop, Mobility(TM) RADEON(TM) 9600 for the notebook and
MOBILITY(TM) RADEON(TM) 7000 IGP for the value segment, in time for the Spring
refresh, ATI again delivers true top-to-bottom leadership in our core PC
market," said David Orton, President and Chief Operating Officer, ATI
Technologies Inc.

Outlook
ATI expects revenues in the third quarter in the $300 million range. Gross
margin, as a percentage of revenues, for the third quarter is expected to
improve slightly. Operating expenses, excluding intangibles and other charges,
for the third quarter are expected to be slightly higher than the second quarter
of this year. As the year progresses, ATI's Consumer products are expected to
begin to show a positive and increasing contribution relative to the first half
of the year. As a result of the above, overall net income should continue to
improve in the third and fourth quarters of fiscal 2003.

Operational Highlights
Desktop
ATI continued to generate strong demand for the RADEON(TM) 9700 and RADEON(TM)
9000 family of products during the second quarter. ATI expanded its product
leadership again, in March, with the introduction of the RADEON(TM) 9800 PRO,
RADEON(TM) 9600 and RADEON(TM) 9200 visual processors targeting the high-end
enthusiast, performance and mainstream desktop markets respectively. Each is the
fastest and highest performing visual processor in its category and represents
the second generation of ATI's breakthrough cinematic rendering architecture.

These new products ignited a second wave of design wins with key OEMs such as
Fujitsu, Gateway, and NEC as well as gaming-focused system integrators such as
Alienware, Falcon Northwest and Voodoo.




                                                                         5 of 26


With the RADEON(TM) 9700 PRO, ATI was the first company to market with
Microsoft(R) DirectX(R) 9.0-compatible hardware, one of key enablers of
cinematic rendering. ATI was first to market again with DirectX(R) 9.0
compatible software when it introduced DirectX(R) 9.0 software drivers
simultaneously with the Microsoft(R) DirectX(R) 9.0 release, on December 20,
2002.

Notebook
ATI strengthened its leading position in the notebook market during the quarter
adding to the array of wins for Mobility(TM) RADEON(TM) based processors -
including wins from Acer, Dell, Fujitsu, IBM, NEC and Sony. On March 13, ATI
introduced the Mobility(TM) RADEON(TM) 9600 - the world's first mobile
DirectX(R) 9.0-compatible VPU featuring innovative overdrive and memory
technologies, astonishing performance levels and vivid cinematic imagery.

In the value portion of the notebook market ATI enjoyed continuing demand for
RADEON(TM)-powered IGP solutions. Last week, ATI built on the success of its
RADEON(TM) IGP 320 and RADEON(TM) IGP 340 chipsets when it introduced the
MOBILITY(TM) RADEON(TM) 7000 IGP the world's most powerful, feature-rich mobile
integrated graphics processor.

Consumer
In ATI's consumer business, set-top box manufacturers including Phillips, Alps
and Proton selected ATI's Xilleon(TM) and NxtWave solutions for their new
products during the quarter. Subsequent to quarter-end the Company announced
further wins in the DTV area, including design wins with ChangHong, China's
leading TV manufacturer for both high definition televisions and digital set-top
boxes.

ATI also announced, subsequent to quarter-end, that it had entered into a
technology development agreement with Nintendo Co., Ltd. Under the agreement,
ATI and Nintendo are developing technologies for use in Nintendo products.

Other Corporate Developments
During the second quarter, ATI announced that it was closing its European
manufacturing operations (ATEL) based in Dublin, Ireland. This closure is a
result of the Company's shift to a new business model which resulted in the
Company transitioning from supplying board-level product to chip-level product.
Consequently, ATI no longer requires manufacturing operations in Europe.




                                                                         6 of 26

Management's Discussion and Analysis of Interim Financial Results

Revenues
ATI revenues for the second quarter decreased slightly to $318.5 from $322.0
million in the first quarter primarily due to a decline in royalty income.

On a year-over-year basis, revenues in the second quarter and the first six
months were up 19.7 and 24.1 per cent respectively. These increases reflect the
success of ATI's new products including the RADEON(TM) 9700, RADEON(TM) 9000 and
the RADEON(TM) IGP family of visual processing solutions.

Gross Margin
Gross margin for the second quarter improved to 28.9 per cent of revenues
compared to 27.3 per cent in the first quarter. Margin for the first quarter was
adversely affected by a writedown taken on the value of certain inventories,
which was not a factor during the second quarter. Although margin on product
sales improved during the quarter, the significant quarterly decline in royalty
income substantially offset this improvement. Excluding royalty income, margin
improved from 24.0 per cent to 27.9 per cent.

On a year-over-year basis, gross margin as a percentage of revenues for the
second quarter and the first six months of the year declined from 33.8 per cent
and 33.0 per cent to 28.9 per cent and 28.1 per cent respectively. These
declines were largely a result of a general decline in discrete mobile product
gross margin during the fiscal 2003 periods.

Operating Expenses
Operating Expenses, Excluding Amortization of Intangibles and Other Charges
- ---------------------------------------------------------------------------
Operating expenses, excluding the amortization of intangibles and other charges,
were $80.3 million in the second quarter, up slightly from the first quarter
levels of $79.6 million. The increase came primarily from continued investment
in R&D.

On a year-over-year basis, total operating expenses, excluding the amortization
of intangibles and other charges, for the second quarter and the first six
months of the year increased 15.0 and 15.1 per cent to $80.3 million and $159.9
million respectively. Higher operating expense levels were primarily a result of
increasing investments in R&D, both headcount and the cost of technology
required to support the increasingly more complex chips; as well as to a lesser
extent, volume related selling expenses.


                                                                         7 of 26

Other Charges
- -------------
The Company incurred other charges during the quarter that have been excluded
from the Company's adjusted net income calculation. These other charges included
$8.0 million to settle the U.S. class action law suit, a portion of which is
expected to be paid by ATI's insurer; $2.8 million related to costs incurred in
connection with the work of the independent Special Committee of the Board
relating to the Ontario Securities Commission investigation and Notice of
Hearing; $2.8 million resulting from the closure of the European manufacturing
operations (ATEL); and $2.4 million in lease termination charges related to
surplus space in leased buildings. These charges are not considered to be part
of the Company's normalized ongoing operations. Please see Note 7 to the
consolidated financial statements.

Total Operating Expenses
- ------------------------
Total operating expenses were $99.5 million in the second quarter, up $16.7
million from first quarter levels of $82.8 million. The increase came primarily
from the other charges outlined above.

On a year-over-year basis, total operating expenses for the second quarter
increased 9.3 per cent. Higher operating expense levels were mostly a result of:
increasing investments in R&D, both headcount and the cost of technology
required to support the increasingly more complex chips; other charges outlined
above; as well as to a lesser extent volume-related selling expenses. These
items were offset by lower expenses for goodwill and intangible assets in fiscal
2003 due to the adoption of the accounting policies relating to the treatment of
goodwill and intangible assets.

Total operating expenses for the first six months of the year of $182.2 million
increased slightly compared to $181.3 million for the same period a year ago as
a result of: increasing investments in R&D, both headcount and the cost of
technology required to support the increasingly more complex chips, other
charges outlined above; as well as to a lesser extent, volume-related selling
expenses. The increase in expense due to these factors was almost entirely
offset by lower expenses for goodwill and intangible assets in fiscal 2003 due
to the adoption of the accounting policies relating to the treatment of goodwill
and intangible assets.


                                                                         8 of 26

Net Income
- ----------
The net loss in the second quarter of fiscal 2003 was $8.3 million or $0.04 per
share compared to net income of $5.0 million or $0.02 per share for the first
quarter of fiscal 2003. Strong revenue and an improving gross margin performance
were largely offset by significant, but largely non-recurring other charges
described above.

On a year-over-year basis, the net loss for the second quarter widened from $3.0
million in fiscal 2002 to $8.3 million for the same quarter this year as a
result of the other charges described above, increased investment in R&D, as
well as a decline in gross margin as a percentage of revenues. This was offset
by lower expenses for goodwill and intangible assets in fiscal 2003 due to the
adoption of the accounting policies relating to the treatment of goodwill and
intangible assets.

The net loss for the first six months of fiscal 2003 narrowed to $3.3 million
compared to $13.4 million for the same period last year due to lower expenses
for goodwill and intangible assets in fiscal 2003 as a result of the adoption of
the accounting policies relating to the treatment of goodwill and intangible
assets, offset by other charges incurred in the second quarter and increased
investment in R&D.

Adjusted net income(1) for the second quarter was $9.7 million or $0.04 per
share compared to $7.0 million or $0.03 per share for the previous quarter.
Improving gross margin was largely responsible for the increase in adjusted net
income.

On a year-over-year basis, adjusted net income for the second quarter and the
first six months of the year declined from $0.07 and $0.11 to $0.04 and $0.07
respectively largely as a result of reduced gross margin as a percentage of
revenues and higher operating expenses, which were largely due to increased
investment in R&D, somewhat offset by an increase in revenue.

(1)Adjusted net income excludes the after-tax effect of gain on investments,
after-tax effect of other charges described in Note 7 to the consolidated
financial statements, amortization of goodwill and intangible assets related to
the Company's acquisitions, and deferred tax recovery of future tax liability
pertaining to intangible assets acquired, related to the Company's acquisitions.
Each of these items has been excluded from adjusted net income as they are not
considered to be part of the Company's normalized ongoing operations. While the
Company recognizes that adjusted net income does not have any standardized
meaning described by generally accepted accounting principles, or GAAP, and that
its adjusted net income calculation cannot be used as a comparison to other
companies' financial performance, ATI believes that its adjusted net income more
appropriately reflects the Company's operating performance. Please see the table
titled "Adjusted Net Income - Reconciliation" below in this news release for the
reconciliation between adjusted net income and net income which is determined in
accordance with GAAP.


                                                                         9 of 26

Liquidity and Financial Resources
ATI's cash flow from operations was $46.0 million in the second quarter of
fiscal 2003, compared to cash used in operations of $31.0 million in the first
quarter of fiscal 2003. The increase in cash flow was primarily a result of
lower inventory levels.

Inventory levels declined significantly to $131.3 million at the end of the
second quarter compared to both the first quarter of 2003, where inventory was
$172.4 million and at year-end where inventory levels were $175.3 million.
Inventories were higher in those previous periods due to a major product
transition and are now at an appropriate level to support current sales.

As of February 28, 2003, ATI had working capital of $380.3 million, compared to
$361.7 million at August 31, 2002. The Company's cash position, including
short-term investments, was $240.9 million as of quarter end, compared to $200.1
million last quarter. The increase was largely due to the reduction in inventory
levels. The Company's cash position as at February 28, 2003 of $240.9 million
was at about the same level as August 31, 2002. The Company is also in the
process of renegotiating its credit facility (see Note 3 to the consolidated
financial statements).

Intangible assets other than goodwill declined to $13.3 million at the end of
the second quarter of fiscal 2003, from $21.9 million at August 31, 2002. The
decline in these assets was due to continued amortization. During the first
quarter the Company reclassified $2.3 million relating to workforce from
intangible assets to goodwill as a result of the adoption of CICA Handbook
Section 3062.

As discussed previously, the Company in the first quarter of fiscal 2003 adopted
the new accounting policies relating to the treatment of goodwill and intangible
assets (CICA Handbook Section 3062) and therefore is no longer amortizing these
assets. Goodwill, which is associated primarily with the prior acquisition of
ArtX, is currently $190.1 million and will be tested for impairment on an annual
basis. The Company has completed the transitional goodwill impairment assessment
during the second quarter of 2003 and has determined no impairment existed as of
September 1, 2002.

Receivables were $200.4 million, up $36.1 million from the end of fiscal 2002
due to continued strong sales in the first half of the year.


                                                                        10 of 26

Claims and Proceedings
In January, the Company announced that Staff of the Ontario Securities
Commission had filed a Notice of Hearing and Statement of Allegations in
relation to ATI and others. The Notice alleged that ATI 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 ATI made a misleading
statement to Staff of the Commission in August 2000 regarding the events leading
up to the disclosure on May 24, 2000 of the shortfall. Seven individuals are
also named in the Notice. The Notice alleged that six of these individuals,
including K.Y. Ho, the Chief Executive Officer of ATI, engaged in insider
trading contrary to the Securities Act. A date for the hearing has not been
fixed.

A Special Committee consisting of Paul Russo, who joined the board in January
2002, is conducting, on behalf of the Board, an independent review of the
concerns raised by Staff with the assistance of independent professional
advisors. The Board intends to consider the input from the Special Committee and
take action in the best interest of shareholders.

In February, the Company announced that it had reached an agreement for the full
and complete settlement of all remaining claims alleged in the shareholder class
action lawsuits filed in May 2001 in the United States District Court for the
Eastern District of Pennsylvania. The terms of the Stipulation and Agreement of
Settlement, which are subject to final court approval and notice to class
members, include no admission of liability or wrongdoing by the Company or other
defendants. The court will hold a fairness hearing on April 25, 2003 to consider
objections, if any, and to determine whether it will approve the settlement.
Under the terms of the settlement, ATI has paid $8 million into court pending
final approval. A portion of this amount is expected to be paid by ATI's
insurer, but has not yet been recognized.


                                                                        11 of 26

Adjusted Net Income - Reconciliation
The table below presents adjusted net income and adjusted net income per share,
which excludes the after-tax effect of gain on investments, after-tax effect of
other charges, amortization of goodwill(1) and intangible assets related to the
Company's acquisitions, and deferred tax recovery of future tax liability
pertaining to intangible assets acquired, related to the Company's acquisitions.

Forward-looking Statements and Uncertainties
Certain statements in this release constitute "forward-looking statements." When
used in this release, words such as "plans," "intends," "anticipates," "should,"
"estimates," "expects," "believes," "indicates," "targeting," "suggests," and
similar expressions are intended to identify forward-looking statements.
Forward-looking statements are based on current expectations and entail various
risks and uncertainties that are outlined in this release and in the Company's
2002 Annual Report and 2002 Annual Information Form. As a result of these risks
and uncertainties, the Company's operating results and common share price may be
subject to significant volatility, particularly on a quarterly basis. For
example, the markets for the Company's products are characterized by changing
market conditions, frequent new product introductions, seasonal and variable
demand and rapid technology changes. Other factors that could cause the
Company's results to vary include, but are not limited to, lack of anticipated
growth in the demand for PCs, gaming consoles and consumer electronic devices in
which the Company's products are incorporated, reductions in the Company's
average selling prices for its products due to competitive pressures and other
factors, the introduction of new products by the Company's competitors which
render the Company's products non-competitive, delays encountered by the Company
in developing new products or enhancements, including integrated graphics and
core logic components, in the time frame required by its customers, delays in
manufacturing or unfavourable manufacturing yields experienced by the Company's
independent foundries, unexpected variances in material costs, including silicon
wafer, memory and printed circuit boards, and constraints on the supply of
components utilized in the Company's products and in the PC industry generally.
These risks and uncertainties could cause or contribute to actual results that
are materially different from those anticipated or experienced in the past.
Additional information concerning factors that could cause the Company's
financial results to fluctuate is contained in the Company's filings with
Canadian and U.S. securities regulatory authorities. ATI disclaims any
obligation or intention to update or revise any forward-looking statement,
whether as a result of new information, future events or otherwise.

The principal business activities of ATI Technologies Inc. (the "Company") are
the design, manufacture and sale of 3D graphics and digital media silicon
solutions. The Company markets its products to original equipment manufacturers,
system builders, distributors and retailers primarily in North America, Europe
and Asia-Pacific.


1.  SIGNIFICANT ACCOUNTING POLICIES

The accompanying unaudited financial statements are prepared in accordance with
Canadian generally accepted accounting principles for interim financial
statements. These financial statements and notes related thereto should be read
in conjunction with the Company's most recent annual consolidated financial
statements, as at and for the year ended August 31, 2002.

These consolidated financial statements follow the same accounting policies and
methods of their application as the most recent annual consolidated financial
statements with the exception of the following:

(a)  CICA Handbook Section 3870, Stock-based Compensation and Other Stock-based
     Payments:

     Effective September 1, 2002, the Company adopted Stock-based Compensation
     and Other Stock-based Payments in CICA Handbook Section 3870, which
     establishes standards for the recognition, measurement and disclosure of
     stock-based compensation and other stock-based payments made in exchange
     for goods and services provided by employees and non-employees. The
     standard requires that a fair value based method of accounting be applied
     to all stock-based payments to non-employees and to employee awards that
     are direct awards of stock, that call for settlement in cash or other
     assets or are stock appreciation rights that call for settlement by the
     issuance of equity instruments. However, the new standard permits the
     Company to continue its existing policy of recording no compensation cost
     on the grant of stock options to employees with the addition of pro forma
     information. The Company has applied the pro forma disclosure provisions of
     the new standard to awards granted on or after September 1, 2002. No
     restatement of prior periods was required as a result of the adoption of
     the new standard. Consideration paid by employees on the exercise of stock
     options is recorded as share capital. See Note 11 for the pro forma
     disclosure as required by this standard.

(b)  CICA Handbook Section 1581, Business Combinations, and Section 3062,
     Goodwill and Other Intangible Assets: In September 2001, the CICA issued
     Handbook Sections 1581 "Business Combinations" and 3062 "Goodwill and Other
     Intangible Assets". The new standards mandate the purchase method of
     accounting for business combinations and require that goodwill no longer be
     amortized but instead be tested for impairment at least annually. The
     standards also specify criteria that intangible assets must meet to be
     recognized and reported apart from goodwill. The standards require that the
     value of the shares issued in a business combination be measured using the
     average share price for a reasonable period before and after the date the
     terms of the acquisition are agreed to and announced. Previously, the
     consummation date was used to value the shares issued in a business
     combination.

     The Company has fully adopted these new standards as of September 1, 2002,
     and has discontinued amortization of all existing goodwill. The Company has
     also reviewed existing intangible assets, including estimates of remaining
     lives, and has reclassified $2.3 million from workforce to goodwill as of
     September 1, 2002 to conform with the new criteria.



                                                                        17 of 26

1.   SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

(b)  CICA Handbook Section 1581, Business Combinations, and Section 3062,
     Goodwill and Other Intangible Assets (continued):

     In connection with Section 3062's transitional goodwill impairment
     evaluation, the Company is required to assess whether goodwill is impaired
     as of September 1, 2002. The Company has completed the transitional
     goodwill impairment assessment during the second quarter of 2003 and has
     determined that no impairment existed as of September 1, 2002.


     Effective September 1, 2002, the Company had unamortized goodwill of $190.1
     million which is no longer being amortized. This change in accounting
     policy is not applied retroactively and the amounts presented for prior
     periods have not been restated for this change. The impact of this change
     is as follows:

Amortization expense related to intangible assets amounted to $3.2 million and
$6.3 million for the three months and six months ended February 28, 2003
respectively (2002 - $2.2 million and $4.3 million). Amortization expense
related to goodwill was nil for the three months and six months ended February
28, 2003 (2002 - $19.0 million and $38.1 million).


3.   CREDIT FACILITY

The Company had previously maintained bank credit facilities aggregating $103
million with a single financial institution, which it allowed to expire. There
were no borrowings outstanding under these facilities. The Company believes that
although its current cash resources are sufficient to meet operating
requirements on an ongoing basis, as a matter of prudence, the Company has
commenced the renegotiation of a syndicated credit facility.

4.   LONG-TERM DEBT (CONTINUED)

(i)  Obligation under capital lease:

     The Company's obligation under capital lease represents the lease on the
     building facility in Markham, Ontario.

(ii) Mortgage payable:

     On  September 10, 2002, the joint venture, Commerce Valley Realty Holding
     Inc. ("CVRH"), in which the Company has a 50 per cent ownership interest
     entered into a mortgage agreement with a lender to finance the building
     facility in Markham, Ontario. The Company's proportionate share of the
     mortgage amounted to $10.8 million (Cdn. $16.9 million), and the
     mortgage has a repayment term of 12 years bearing interest at a rate of
     6.96 per cent per annum. The underlying mortgage is denominated in
     Canadian dollars. Funding under the mortgage was received in October 2002.


5.   GUARANTEE

The Company and other owners of CVRH have jointly and severally provided a
guarantee for the mortgage payment of the building facility in Markham, Ontario.
In the event that CVRH is unable to meet the underlying mortgage payment to the
lender, the Company and other owners of CVRH will be jointly and severally
responsible for it under this guarantee. The monthly mortgage interest and
principal payment amounts to approximately $0.2 million. The mortgage has a
repayment term of 12 years with a maturity date on November 1, 2014. As of
February 28, 2003, the outstanding amount of the mortgage stood at $22.4 million
(Cdn. $33.3 million).

In addition, the Company posted a letter of credit in the amount $2.0 million
(Cdn. $3.0 million) in favour of CVRH and CVRH, in turn, assigned this letter of
credit for the exclusive benefit of the lender as additional security of the
mortgage. The letter of credit has a term of 5 years and will expire on November
5, 2007. In the event of a lease default by the Company, the proceeds of the
letter of credit will be paid to the lender.


6.   LOSS ON INTEREST RATE SWAP

In fiscal 2001, CVRH entered into an interest rate swap contract to hedge its
exposure to the interest rate risk applicable to its mortgage for the 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 balance sheet 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.




                                                                        20 of 26

     an agreement for the full and complete settlement of all
     remaining claims alleged in the shareholder class action
     lawsuits filed in May 2001 in the United States District Court
     for the Eastern District of Pennsylvania. This litigation
     relates to alleged misrepresentations and omissions made by
     the Company and certain directors and officers during a period
     preceding its May 2000 earnings warning. This litigation was
     settled, with no admission of liability, for the amount of
     $8.0 million. This amount was subsequently paid on February
     12, 2003, into Court pending final approval.

(ii) OSC Notice of Hearing

     In January, the Company announced that Staff of the Ontario
     Securities Commission had filed a Notice of Hearing and
     Statement of Allegations in relation to ATI and others. The
     Notice alleged that ATI 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 ATI made a misleading statement to Staff of
     the Commission in August 2000 regarding the events leading up
     to the disclosure on May 24, 2000 of the shortfall. Seven
     individuals are also named in the Notice. The Notice alleged
     that six of these individuals, including K.Y. Ho, the Chief
     Executive Officer of ATI, engaged in insider trading contrary
     to the Securities Act. A date for the hearing has not been
     fixed. The Company has set up a special committee to conduct
     an independent review of the concerns raised by OSC staff.
     As of February 28, 2003, the Company incurred external charges
     totaling $2.8 million in connection with this matter.

(iii)Restructuring charge - Europe

     During the second quarter, the Company announced the closure
     of ATI Technologies (Europe) Ltd. ("ATEL"), its subsidiary in
     Dublin, Ireland. The Company has successfully shifted its
     European business model from direct selling to marketing its
     graphic chip technology to original design manufacturers (ODM)
     and add-in-board (AIB) partners to serve European original
     equipment manufacturers (OEM), the system builders and
     distribution channels. The transition has resulted in the
     redundancy of the operations in Dublin.



                                                                        21 of 26

7.   OTHER CHARGES (CONTINUED)

(iii)Restructuring charge - Europe (continued)

     The Company recorded a pre-tax charge of $2.8 million related
     to the closure of ATEL for the fiscal quarter. The following
     table details the components of the charge:




       (Thousands of US dollars)
       ----------------------------------------------
       Components                             Amount
       ----------------------------------------------
                                           
       Exit and other costs                     1,365
       Asset impairment (non-cash)              1,400
       ----------------------------------------------
       Total                                  $ 2,765
       ==============================================




     The following table details the activity through the accrued
     restructuring liability for the quarter ended February 28,
     2003:




       (Thousands of US dollars)
       -----------------------------------------------
                                           
       Balance at December 1, 2002            $     -
       Provision                                1,365
       Cash payments                                -
       -----------------------------------------------
       Balance at February 28, 2003           $ 1,365
       ===============================================



     The asset impairment is due to the write-down of the building facility in
     Dublin, Ireland to fair value less cost to sell. The building facility,
     which has a fair value of $1.9 million, is included in the capital
     assets for financial statement presentation purposes. The Company
     expects to complete the major components of its exit plan for ATEL by
     July 2003 and to pay out the cash portion of the restructuring charge by
     the end of the fiscal year.

(iv) Lease exit charge

     During the fiscal quarter, the Company determined that it would exit
     certain leased properties located in Markham, Ontario. As a result,
     the Company recognized the fair value of the future net costs
     related to the leases as a charge for the fiscal quarter.



                                                                        22 of 26

The weighted average estimated fair values at the date of grant for the options
granted for the three months and six months ended February 28, 2003 was $2.41
and $2.65 per share respectively. The "fair value" of each option granted was
estimated on the date of the grant using the Black-Scholes option pricing model

For purposes of pro forma disclosures, the estimated fair value of the options
is amortized to expense over the options' vesting period on a straight-line
basis.
