                         EXFO POSTS STRONG SALES GROWTH
                 TO REACH US$20.5 MILLION IN THE THIRD QUARTER


|X|    SALES INCREASE OF 35.4% COMPARED TO THIRD QUARTER OF 2003 AND 21.2%
       COMPARED TO SECOND QUARTER OF 2004

|X|    FTTP TEST SOLUTIONS GENERATE HIGHER THAN EXPECTED REVENUES

|X|    GAAP NET LOSS IMPROVES TO US$0.02 PER SHARE


QUEBEC CITY, CANADA, June 29, 2004--EXFO Electro-Optical Engineering Inc.
(NASDAQ: EXFO, TSX: EXF) reported today sales growth of 35.4% to reach US$20.5
million in the third quarter ended May 31, 2004, from US$15.1 million in the
third quarter of 2003 and 21.2% growth from US$16.9 million in the second
quarter of 2004.

The net book-to-bill ratio was 0.98 for the third quarter of fiscal 2004
compared to 0.93 for the same period last year and 1.05 for the second quarter
of 2004.

Gross margin amounted to 52.9% of sales in the third quarter of fiscal 2004
compared to 41.6% (excluding inventory write-offs) in the third quarter of 2003
and 55.4% in the second quarter of 2004.

GAAP net loss for the third quarter of fiscal 2004 totaled US$1.2 million, or
US$0.02 per share, compared to a net loss of US$38.4 million, or US$0.61 per
share, for the third quarter of 2003 and a net loss of US$2.9 million, or
US$0.04 per share, for the second quarter of 2004.

"Thanks to continued market-share gains, strategic focus and early success in
the fiber-to-the-premises (FTTP) market opportunity, EXFO has achieved
remarkable sales growth in a relatively flat spending environment," said Germain
Lamonde, EXFO's Chairman, President and CEO. "This marked our best sales and
bookings quarter since the fourth quarter of 2001 with significant progress
towards profitability. In fact, we would have been profitable last quarter,
excluding amortization of intangible assets and stock-based compensation costs."

"It is becoming clear that focusing on top-line growth through market-share
gains and operational excellence is the right strategy to bring us back to
profitability," Mr. Lamonde added. "I believe that our decision to sustain R&D
investments in our fiber-to-the premises (FTTP) and next-generation IP
networking test solutions will pay off."

THIRD-QUARTER BUSINESS HIGHLIGHTS

   |X|   Confirming its market leadership in the physical-layer field-testing
         market, EXFO shipped a series of orders--many of which were
         FTTP-related--to a Tier-1 network service provider. The majority of
         FTTP-related sales were derived from established products.

   |X|   Remaining focused on market-driven innovation, EXFO launched three new
         products in the third quarter, including a next-generation optical time
         domain reflectometer (OTDR) available in the FTTP configuration.
         Following the quarter-end, EXFO introduced three additional products:
         all-in-one MultiTest module, next-generation Fibre Channel test
         module--both housed inside the leading FTB-400 field-testing
         platform--and a Passive Optical Network (PON) power meter. EXFO has
         introduced 20 new products so far in fiscal 2004.

   |X|   To renew with profitability, EXFO generated higher sales volumes and
         better absorbed its operating costs. Based on a GAAP net loss of US$1.2
         million and excluding amortization of intangible assets of US$1.3
         million and stock-based compensation costs of US$200,000, the company
         would have been profitable (at US$273,000). EXFO also reported positive
         cash flows from operations for the second consecutive quarter (at
         US$605,000).

OPERATING EXPENSES
Selling and administrative expenses amounted to US$6.9 million, or 33.9% of
sales, for the third quarter of fiscal 2004 compared to US$7.1 million, or 46.7%
of sales, for the same period last year and US$6.8 million, or 40.0% of sales,
for the second quarter of 2004.

Gross research and development expenses totaled US$4.2 million, or 20.4% of
sales, in the third quarter of fiscal 2004 compared to US$4.6 million, or 30.7%
of sales, in the third quarter of 2003 and US$4.3 million, or 25.4% of sales, in
the second quarter of 2004.

BUSINESS OUTLOOK
EXFO forecasted sales between US$19.0 million and US$22.0 million and a GAAP net
loss between US$0.03 and US$0.00 per share for the fourth quarter of fiscal
2004.

             NOTES TO INTERIM CONSOLIDATED FINANCIAL STATEMENTSYEARS

                  (tabular amounts in thousands of US dollars,
            except share and per share data and as otherwise noted)


1    INTERIM FINANCIAL INFORMATION

     The financial information as at May 31, 2004, and for the three and
     nine-month periods ended May 31, 2003 and 2004, is unaudited. In the
     opinion of management, all adjustments necessary to present fairly the
     results of these periods in accordance with generally accepted accounting
     principles in Canada have been included. The adjustments made were of a
     normal recurring nature. Interim results may not necessarily be indicative
     of results anticipated for the entire year.

     These interim consolidated financial statements are prepared in accordance
     with generally accepted accounting principles in Canada and use the same
     accounting policies and methods used in the preparation of the company's
     most recent annual consolidated financial statements, except for changes as
     described in note 2. All disclosures required for annual financial
     statements have not been included in these financial statements. These
     interim consolidated financial statements should be read in conjunction
     with the company's most recent annual consolidated financial statements.

     Certain comparative figures have been reclassified to conform to the
     current periods' presentation.


2    NEW ACCOUNTING STANDARDS AND PRONOUNCEMENTS

     On September 1, 2003, the company implemented the documentation required by
     Accounting Guideline 13 of the Canadian Institute of Chartered Accountants
     (CICA) handbook, "Hedging Relationship", which establishes new rules for
     designating, documenting and assessing the effectiveness of hedging
     relationships, such as the company's forward exchange contracts. If these
     new rules are not met, hedge accounting can not be applied. Consequently,
     the company's forward exchange contracts, which are used to hedge
     anticipated US-dollar denominated sales, continue to qualify for hedge
     accounting; foreign exchange translation gains and losses on these
     contracts continue to be recognized as an adjustment of the revenue when
     the sales are recorded.

     On September 1, 2003, the company prospectively adopted the amendments made
     to handbook section 3870, "Stock-Based Compensation and Other Stock-Based
     Payments". These amendments require an expense to be recognized in
     financial statements for all forms of employee stock-based compensation,
     including stock options, using a fair value-based method. During the nine
     months ended May 31, 2004, the company granted 506,500 stock options to its
     employees. The aggregate fair value of these stock options amounts to
     $1,463,000. The corresponding stock-based compensation costs were amortized
     using the graded vesting method, resulting in stock-based compensation
     costs of $200,000 and $289,000 for the three months and the nine months
     ended May 31, 2004, respectively.

     The company is required to disclose pro forma information with respect to
     net loss and net loss per share as if stock-based compensation costs were
     recognized in the financial statements using the fair value-based method
     for options granted in fiscal 2003. However, if the fair value-based method
     had been used to account for these costs, there would have been no
     significant differences in the net loss and net loss per share figures,
     compared to the net loss and net loss per share figures on a pro forma
     basis. Consequently, no pro forma information is provided in these interim
     consolidated financial statements.

                  (tabular amounts in thousands of US dollars,
            except share and per share data and as otherwise noted)


     The fair value of options granted in fiscal 2004 was estimated using the
     Black-Scholes options valuation model with the following weighted average
     assumptions:

                                   THREE MONTHS ENDED        NINE MONTHS ENDED

                                                   (UNAUDITED)

     Risk-free interest rate                 2.2%                     2.7%
     Expected volatility                      98%                     100%
     Dividend yield                           Nil                      Nil
     Expected life                      47 months                49 months

     In July 2003, the CICA issued handbook sections 1100 and 1400, "Generally
     Accepted Accounting Principles" and "General Standards of Financial
     Statements Presentation", which are effective for fiscal years beginning on
     or after October 1, 2003. Among other things, these new sections define
     generally accepted accounting principles (GAAP), establish the relative
     authority of various types of CICA Accounting Standards Board
     pronouncements and clarify the role of "industry practice" in applying
     GAAP. The company will adopt these new standards on September 1, 2004 and
     it does not expect significant impacts on its financial statements.

5    WARRANTY

     The company offers its customers warranties of one to three years,
     depending on the specific products and terms of the customer purchase
     agreement. The company's typical warranties require it to repair or replace
     defective products during the warranty period at no cost to the customer.
     Costs related to original warranties are accrued at the time of shipment,
     based upon estimates of expected rework rates and warranty costs to be
     incurred. Costs associated with extended warranties are charged to expense
     as incurred. Revenue for these extended warranties is recognized on a
     straight-line basis over the warranty period.

     August 31, 2003:

8    INCOME TAXES

     During the first quarter of fiscal 2004, the company recorded $1,406,000
     for the non-recurring recovery of income taxes paid in previous periods
     following the receipt of a tax assessment during that period.

     Furthermore, considering current market conditions and because the company
     recorded operating losses for the current nine-month period and for the
     last two fiscal years, the company has recorded a full valuation allowance
     against future income tax assets on deductible temporary differences, tax
     losses carried forward and tax deductions. This causes its income tax
     recovery to be distorted in relation to its pre-tax accounting income.


9     CONTINGENCY

     On November 27, 2001, a class action suit was filed in the United States
     District Court for the Southern District of New York against the company,
     four of the underwriters of its Initial Public Offering and some of its
     executive officers pursuant to the Securities Exchange Act of 1934 and Rule
     10b-5 promulgated thereunder and sections 11, 12 and 16 of the Securities
     Act of 1933. This class action alleges that the company's registration
     statement and prospectus filed with the Securities and Exchange Commission
     on June 29, 2000, contained material misrepresentations and/or omissions
     resulting from (i) the underwriters allegedly soliciting and receiving
     additional, excessive and undisclosed commissions from certain investors in
     exchange for which they allocated material portions of the shares issued in
     connection with the company's Initial Public Offering; and (ii) the
     underwriters allegedly entering into agreements with customers whereby
     shares issued in connection with the company's Initial Public Offering
     would be allocated to those customers in exchange for which customers
     agreed to purchase additional amounts of shares in the after market at
     pre-determined prices.

                  (tabular amounts in thousands of US dollars,
            except share and per share data and as otherwise noted)


     On April 19, 2002, the plaintiffs filed an amended complaint containing
     master allegations against all of the underwriters in all of the 310 cases
     included in this class action and, also filed an amended complaint
     containing allegations specific to four of the company's underwriters, the
     company and two of its executive officers. In addition to the allegations
     mentioned above, the amended complaint alleges that the underwriters (i)
     used their analysts to manipulate the stock market; and (ii) implemented
     schemes that allowed issuer insiders to sell their shares rapidly after an
     initial public offering and benefit from high market prices. As concerns
     the company and its two executive officers in particular, the amended
     complaint alleges that (i) the company's registration statement was
     materially false and misleading because it failed to disclose the
     additional commissions and compensation to be received by underwriters;
     (ii) the two named executive officers learned of or recklessly disregarded
     the alleged misconduct of the underwriters; (iii) the two named executive
     officers had motive and opportunity to engage in alleged wrongful conduct
     due to personal holdings of the company's stock and the fact that an
     alleged artificially inflated stock price could be used as currency for
     acquisitions; and (iv) the two named executive officers, by virtue of their
     positions with the company, controlled the company and the contents of the
     registration statement and had the ability to prevent its issuance or cause
     it to be corrected. The plaintiffs in this suit seek an unspecified amount
     for damages suffered.

     In July 2002, the issuers filed a motion to dismiss the plaintiffs' amended
     complaint and judgment was rendered on February 19, 2003. Only one of the
     claims against the company was dismissed. On October 8, 2002, the claims
     against its officers were dismissed pursuant to the terms of Reservation of
     Rights and Tolling Agreements entered into with the plaintiffs.

     On June 26, 2003, the Plaintiff's Executive Committee announced that a
     proposed settlement between the issuers and their directors and officers
     and the plaintiffs had been structured. A Memorandum of Understanding
     ("MOU") to settle the plaintiffs' claims against the issuers and their
     directors and officers has now been approved as to form and the process of
     obtaining approval by all parties to the MOU is now underway. The parties
     will be required to prepare many documents necessary to consummate the
     settlement, which will be submitted to the Court for preliminary approval.
     Final approval will be required by the Court following notice to class
     members and a fairness hearing. If this tentative settlement is
     successfully finalized, the company and the individual defendants will be
     released from the litigation. Any direct financial impact of the proposed
     settlement is expected to be borne by the company's insurance carriers.

     Since the settlement process is subject to a fairness hearing and final
     court approval, it is possible that it could fail. Therefore, it is not
     possible to predict the final outcome of the case, nor determine the amount
     of any possible losses. If the settlement process fails, the company will
     continue to defend its position in this litigation that the claims against
     it, and its officers, are without merit. Accordingly, no provision for this
     case has been made in the interim consolidated financial statements as of
     May 31, 2004.

     The diluted loss per share for the periods ended May 31, 2003 and 2004, was
     the same as the basic loss per share since the dilutive effect of stock
     options and restricted stock awards should not be included in the
     calculation; otherwise, the effect would be anti-dilutive. Accordingly,
     diluted loss per share for those periods was calculated using the basic
     weighted average number of shares outstanding.


11    SEGMENT INFORMATION

     In September 2003, the company reorganized its business under two
     reportable segments: Telecom Division and Photonics and Life Sciences
     Division. The Telecom Division meets the physical-, optical- and
     protocol-layer test and measurement needs of network service providers,
     system vendors and component manufacturers throughout the global
     telecommunications industry. The Photonics and Life Sciences Division
     mainly leverages developed and acquired technologies for high-tech
     industrial manufacturing and research markets.

     EXFO's President and Chief Executive Officer ("CEO"), as the chief
     operating decision-maker, assesses the performance of the two segments and
     allocates resources to the segments. Each reportable segment is managed
     separately. Earnings (loss) from operations represent the primary measure
     used by the CEO in assessing performance of the reportable segments. The
     accounting policies of the reportable segments are the same as those
     applied in the consolidated financial statements.

     Until August 31, 2003, the company was organized under one reportable
     segment, being the development, manufacturing and marketing of fiber-optic
     test, measurement and monitoring solutions for the global
     telecommunications industry.

STATEMENTS OF CASH FLOWS

For the periods ended May 31, 2003 and 2004, there are no significant
differences between the statements of cash flows under Canadian GAAP as compared
to U.S. GAAP.

RECONCILIATION ITEM

a)   Forward exchange contracts

     On September 1, 2003, the company implemented the documentation required by
     Accounting Guideline 13 of the CICA handbook "Hedging Relationship" for the
     designation, documentation and assessment of the effectiveness of its
     forward exchange contracts, for the purposes of applying hedge accounting,
     as described in note 2.

     With this documentation in place, the forward exchange contracts entered
     into by the company after September 1, 2003 qualify for hedge accounting
     treatment under U.S. GAAP. Consequently, under U.S. GAAP, changes in the
     fair value of these contracts are charged to other comprehensive loss.
     However, changes in the fair value of contracts entered into prior to
     September 1, 2003 continue to be charged to the statements of earnings.
     Under Canadian GAAP, foreign exchange translation gains and losses on
     contracts entered into either before or after September 1, 2003, are
     recognized as an adjustment of the revenue when the sales are recorded.

NEW ACCOUNTING STANDARD

On September 1, 2003, the company prospectively adopted Statement of Financial
Accounting Standard (SFAS) 123, "Accounting for Stock-Based Compensation", under
the revised transition provisions of SFAS 148, "Accounting for Stock-Based
Compensation - Transition and Disclosure". Upon the adoption of SFAS 123 and
SFAS 148, the company recognized stock-based compensation costs for stock
options granted to employees since September 1, 2003, using the fair value-based
method. The company adopted this Statement in order to conform to the newly
adopted rules under Canadian GAAP, as described in note 2. As a result of the
adoption of the fair value-based method, the accounting for stock-based
compensation under Canadian GAAP and U.S. GAAP is the same.

INDUSTRY OVERVIEW

         Network service providers (NSPs), the first link in the global
telecommunications supply chain, continuously reduced their capital expenditure
(CAPEX) budgets for almost three years, but in the first nine months of fiscal
2004, some measure of stability returned to the marketplace. NSPs even began
investing in growth pockets, such as Voice over Internet Protocol (VoIP) and
fiber-to-the-premises (FTTP), in order to offer end-customers triple-play
services (voice, data and video). These investments, however, were offset by
CAPEX reductions in other areas to produce relatively flat spending patterns
year-over-year.

         This relative stability in CAPEX spending was witnessed in multiple
segments of the global telecommunications industry. System manufacturers
benefited from NSP demand for


                                                                               1


next-generation converged networks and fiber deployments in access areas.
Optical component vendors, who had been hardest hit by the downturn, still
represented a depressed end-market due to scarce demand for new types of
components. Some test and measurement equipment vendors, whose products enable
customers to reduce both CAPEX and operating expenses (OPEX), attracted the
attention of NSPs and system manufacturers, especially those offering test
solutions for VoIP and/or FTTP applications.


COMPANY OVERVIEW

         In the second quarter of fiscal 2004, we began recognizing revenues
from FTTP test solutions. In the third quarter, revenues derived from FTTP test
solutions generated higher-than- expected revenues as we shipped a series of
orders--many of which were FTTP-related--to a Tier-1 NSP that accounted for
25.7% of total sales. This represents an unusually high percentage for the
company, since we typically do not have any 10%-customers in our quarterly sales
figures. The majority of FTTP-related sales were derived from established
products. For the upcoming quarter, we are counting on further market-share
gains and increased acceptance of recently launched products, since we are not
expecting same level of customer concentration.

         Based on our GAAP net loss of $1.2 million in the third quarter of
fiscal 2004 and excluding amortization of intangible assets of $1.3 million and
stock-based compensation costs of $200,000, we would have been profitable
($273,000) mainly due to a larger sales volume. In addition, during that same
quarter, operating activities provided positive cash flows for the second
quarter in a row ($605,000). These positive cash flows from operations enabled
us to meet one of our four strategic annual objectives, which consisted of
maintaining a sound financial position.

         Remaining focused on market-driven innovation, we launched three new
products in the third quarter, including a next-generation optical time-domain
reflectometer (OTDR). This OTDR is available in the 1310/1490/1550-nm
triple-wavelength configuration sanctioned by leading FTTP standards bodies.
Following the quarter-end, we introduced three additional products: all-in-one
MultiTest module, next-generation Fibre Channel test module - both housed inside
the leading FTB-400 filed-testing plateform - and a passive optical network
(PON) power meter. So far in fiscal 2004, we have released 20 new products.

         In the second quarter of fiscal 2004, we introduced seven new products,
including a new line of handheld test instruments that specifically target the
emerging demand for FTTP deployments; as well as our new Packet Blazer TM
Ethernet module, a new protocol-based solution for central offices. In the first
quarter of 2004, we also introduced seven new products, including the 10+
Gigabit Multi-Rate Transceiver with deep channelization and mixed payload
concatenations for next-generation optical networks.

         In addition, during the second quarter of fiscal 2004, we successfully
closed the public offering of 5.2 million subordinate voting shares to a
syndicate of Canadian-based underwriters for net proceeds of $29.2 million
(Cdn$38.4 million). As a result, we had a cash position of $84.7 million as of
May 31, 2004.

         Furthermore, over the last two quarters, we consolidated our
protocol-layer activities in Montreal to increase efficiency and optimize cost
structure.


                                                                               2


         Also, during the third quarter of fiscal 2004, we succesfully renewed
our collective bargaining agreement with our unionized manufacturing employees
in Quebec City, Canada.

         Finally, during the third quarter of fiscal 2004, we performed our
annual impairment test for goodwill and reviewed the carrying value of certain
acquired intangible assets for impairment. Based on our impairment tests, we
concluded that goodwill and these intangible assets were not impaired.

NEW BUSINESS STRUCTURE

         At the beginning of fiscal 2004, we reorganized our business under two
new divisions: Telecom Division and Photonics and Life Sciences Division. Our
objectives behind this reorganization were to simplify our business model, adopt
a market approach rather than a product approach and increase accountability
throughout the organization. Our Telecom Division, which consists of the former
Portable and Monitoring and telecom-related Industrial and Scientific product
lines, meets the physical-, optical- and protocol-layer test and measurement
needs of NSPs, system vendors and component manufacturers throughout the global
telecommunications industry. Our Photonics and Life Sciences Division, which
includes previous non-telecom Industrial and Scientific product lines, mainly
leverages developed and acquired technologies for diverse high-tech industrial
manufacturing and research markets.

         This simplified business structure - with respective sales, marketing,
manufacturing, research and development and management teams for each division -
enables us to better serve our diverse customer base and to maximize shareholder
value.

         EXFO's President and Chief Executive Officer ("CEO"), as the chief
operating decision-maker, assesses the performance of the two segments and
allocates resources to the segments. Earnings (loss) from operations represent
the primary measure used by the CEO in assessing performance of the reportable
segments. Please refer to note 11 to our interim consolidated financial
statements for detailed segment information.

         Until August 31, 2003, the company was organized under one reportable
segment; that is, the development, manufacturing and marketing of fiber-optic
test, measurement and monitoring solutions for the global telecommunications
industry.

         As part of this reorganization and consistent with our overall business
strategy, we are continuously reviewing our various assets.

OUR STRATEGY, KEY PERFORMANCE INDICATORS AND CAPABILITY TO DELIVER RESULTS

         For a complete description of our strategy and the related key
performance indicators as well as our capability to deliver results, please
refer to the corresponding sections in our most recent annual report filed with
the securities commissions.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

         For a complete description of our critical accounting policies and
estimates, please refer to the critical accounting policies and estimates in our
most recent annual report filed with the securities commissions. The following
points detail the changes in critical accounting policies that have occurred
since our most recent annual report:


                                                                               3


         HEDGING RELATIONSHIP. On September 1, 2003, we implemented the
documentation required by Accounting Guideline 13 of the Canadian Institute of
Chartered Accountants (CICA) handbook, "Hedging Relationship", which establishes
new rules for designating, documenting and assessing the effectiveness of
hedging relationships, such as our forward exchange contracts. If these rules
are not met, hedge accounting can not be applied. Consequently, our forward
exchange contracts, which are used to hedge anticipated US-dollar-denominated
sales, continue to qualify for hedge accounting; foreign exchange translation
gains and losses on these contracts continue to be recognized as an adjustment
of the revenue when the sales are recorded.

         STOCK-BASED COMPENSATION COSTS. On September 1, 2003, we prospectively
adopted the amendments made to handbook section 3870, "Stock-Based Compensation
and Other Stock-Based Payments". These amendments require an expense to be
recognized in financial statements for all forms of employee stock-based
compensation, including stock options, using a fair value-based method. The fair
value-based method involves significant subjective assumptions such as the
expected volatility of our stocks and the expected life of the options. During
the nine months ended May 31, 2004, we granted 506,500 stock options to our
employees. The aggregate fair value of these stock options amounted to
$1,463,000. The corresponding stock-based compensation costs were amortized
using the graded vesting method, resulting in stock-based compensation costs of
$200,000 and $289,000 for the three months and the nine months ended May 31,
2004, respectively. Most of these costs have been recorded in selling and
administrative expenses and in research and development expenses in the
statements of earnings.





                                                                               4


RESULTS OF OPERATIONS

SALES

THREE MONTHS ENDED MAY 31, 2004, VS. THREE MONTHS ENDED MAY 31, 2003

         For the three months ended May 31, 2004, our global sales increased
35.4% to $20.5 million from $15.1 million for the same period last year, with a
81%-19% split in favor of our Telecom Division.

TELECOM DIVISION

         For the three months ended May 31, 2004, sales of our Telecom Division
increased 38.3% to $16.7 million from $12.0 million for the same period last
year. During the third quarter of fiscal 2004, revenues from FTTP test solutions
were higher than expected, which contributed to increase our sales. Also, the
positive environment spending helped us to increase our sales for this quarter.
Finally, we believe that we have gained market share for our physical-layer
field-testing products.

         However, despite the significant increase in our Telecom sales in the
third quarter of fiscal 2004, sales of our protocol-layer test solutions
represented less than 10% of our global sales in the third quarter of fiscal
2004. The current protocol-layer test market proves to be highly competitive as
it prepares for deployment of next-generation SONET/SDH and new IP-intensive
architectures. We are remaining confident the solid product portfolio we are
building for this crucial end-market for EXFO will lead to good long-term
growth.

PHOTONICS AND LIFE SCIENCES DIVISION

         For the three months ended May 31, 2004, sales of our Photonics and
Life Sciences Division increased 24.3% to $3.8 million from $3.1 million for the
same period last year. The increase in sales is due to the greater demand for
our high-tech industrial manufacturing solutions, mainly our X-CITETM 120
Fluorescence Illumination System.

         Overall, for the two divisions, net accepted orders increased 41.8% to
$20.0 million in the third quarter of fiscal 2004 from $14.1 million for the
same period last year. The relative stability in CAPEX spending and market-share
gain helped us increase our bookings. Our net book-to-bill ratio rose to 0.98 in
the third quarter of 2004, from 0.93 for the same period last year. In the
previous quarter, the net book-to-bill ratio reached 1.05.

         For the upcoming quarter, we expect the sales split between the two
divisions to remain in the same ranges as for the two previous quarters.

NINE MONTHS ENDED MAY 31, 2004, VS. NINE MONTHS ENDED MAY 31, 2003

         For the nine months ended May 31, 2004, our global sales increased
12.0% to $53.3 million from $47.6 million for the same period last year, with a
79%-21% split in favor of our Telecom Division.

TELECOM DIVISION

         For the nine months ended May 31, 2004, Telecom Division sales
increased 10.9% to $42.1 million from $38.0 million for the same period last
year. As explained above, this significant growth in the third quarter of fiscal
2004 helped us increase our sales year-over-year.


                                                                               7


It should be noted that this division's sales have been increasing since the
last quarter of fiscal 2003.

         Since the last few months, we have been offering new and enhanced
warranty programs, significantly increasing extended-warranty sales. Revenues
from these sales of these warranties are deferred and recognized over the
warranty-period, causing our deferred revenue to increase.

PHOTONICS AND LIFE SCIENCES DIVISION

         For the nine months ended May 31, 2004, Photonics and Life Sciences
Division sales increased 16.0% to $11.2 million from $9.6 million for the same
period last year. This growth in sales is due to the greater demand for our
high-tech industrial manufacturing solutions, mainly our X-CITETM 120
Fluorescence Illumination System.

GEOGRAPHIC DISTRIBUTION

         For the three months ended May 31, 2004, sales to the Americas,
Europe-Middle East- Africa (EMEA) and Asia-Pacific (APAC) accounted for 65%, 20%
and 15% of global sales, respectively. For the corresponding period last year,
sales to the Americas, EMEA and APAC accounted for 72%, 15% and 13% of global
sales, respectively. During the third quarter of fiscal 2003, our sales to the
EMEA and APAC markets were unusually low, thus causing sales to the Americas to
represent a larger portion of our global sales. In the third quarter of fiscal
2004, our sales to the EMEA and APAC markets were closer to their usual level in
percentage of global sales.

         For the nine months ended May 31, 2004, sales to the Americas, EMEA and
APAC accounted for 66%, 18% and 16% of global sales, respectively. For the
corresponding period last year, sales to the Americas, EMEA and APAC accounted
for 66%, 19% and 15%, respectively.

         Through our two divisions, we sell our products to a broad range of
customers, including NSPs, optical component and system manufacturers, as well
as high-tech industrial manufacturers and research and development laboratories.
During the three months ended May 31, 2004, we had an unusually high amount of
sales to a single customer that accounted for 25.7% of our sales. During that
same period, our top three customers accounted for 32.9% of our sales. For the
corresponding period last year, no customer accounted for more than 9.5% of our
sales and our top three customers accounted for 19.4% of our sales the same
period last year. For the nine months ended May 31, 2004, our top customer
accounted for 14.0% of our sales and our top three customers accounted for 21.6%
of our sales. For the nine months ended May 31, 2003, no customer accounted for
more than 6.5% of sales and our top three customers accounted for 19.4% of our
sales for that same period.

         Considering the sales level and the net book-to-bill ratio for the
first three quarters of fiscal 2004 as well as the expected market-share gain in
protocol-testing and FTTP solutions, we still believe that we will achieve our
KPI; that is, 10% sales growth year-over-year in a stable or slightly declining
telecommunications market.


GROSS MARGIN

         Gross margin amounted to 52.9% of sales for the three months ended May
31, 2004, compared to 30.7% for the same period last year. For the three months
ended May 31, 2003,


                                                                               8


we recorded write-offs for excess and obsolete inventories of $1.6 million.
Excluding this special charge, gross margin would have reached 41.6% of sales
for that period. The increase in our gross margin can be explained by several
factors. First, the rise in sales (35.4% year-over-year) has undoubtedly helped
increase our gross margin during the quarter. Increased manufacturing activities
allowed us to better absorb our fixed manufacturing costs. In addition, our
cost-reduction measures and our enhanced efficiency further contributed to the
increase in gross margin. However, the increase was offset in part by the shift
in the geographic distribution of our sales. In the third quarter of 2004, this
shift resulted in more sales made to the EMEA and APAC markets, where gross
margins tend to be lower. Also, a stronger Canadian dollar, compared to the US
dollar year-over-year, prevented us, to some extent, from further improving our
gross margin as some cost of sales elements are denominated in Canadian dollars.

         Our gross margin amounted to 53.1% of sales for the nine months ended
May 31, 2004, compared to 44.5% for the same period last year. Excluding the
special charge recorded in the third quarter of fiscal 2003 for excess and
obsolete inventories, gross margin would have reached 47.9% of sales for the
nine months ended May 31, 2003. The increase in our gross margin can be
explained by the increase in our sales, the positive effects of our cost-cutting
measures, our enhanced efficiency and increased manufacturing activities, which
led to a better absorption of our fixed manufacturing costs. However, a stronger
Canadian dollar, compared to the US dollar year-over-year, prevented us, to some
extent, from further improving our gross margin.

         The 53.1% gross margin reached for the nine months ended May 31, 2004,
leads us to believe that our 50% gross margin objective for fiscal 2004 will be
attained.

         Our gross margin may fluctuate quarter-over-quarter as our sales may
fluctuate. Furthermore, our gross margin can be negatively affected by increased
competitive pricing pressure, increased obsolescence costs, shifts in product
mix, under-absorption of fixed manufacturing costs and increases in product
offerings by other suppliers in our industry.

         It should be noted that a new presentation was adopted, where certain
expenses were reclassified from selling and administrative expenses to cost of
sales. Consequently, comparative figures have also been reclassified, resulting
in a cost of sales increase of 4.0% and 2.8% for the three and nine months ended
May 31, 2003, respectively, with comparable percentage of sales decreases in
selling and administrative expenses for these same periods.


SELLING AND ADMINISTRATIVE

         For the three months ended May 31, 2004, selling and administrative
expenses were $6.9 million, or 33.9% of sales, compared to $7.1 million, or
46.7% of sales for the same period last year. Our restructuring actions combined
with tight cost-control measures contributed to the reduction of our selling and
administrative expenses year-over-year. However, several factors prevented us
from further reducing these expenses year-over-year. Higher sales volume in the
third quarter of fiscal 2004, compared to the same period last year caused our
commission expenses to increase. In addition, since September 1, 2003, we
account for the non-cash stock-based compensation costs related to awards
granted to our employees, which caused our selling and administrative expenses
to increase $115,000 year-over-year. Finally, a stronger Canadian dollar,
compared to the US dollar year-over-year, further increased our selling and
administrative expenses, as some of our selling and administrative expenses are
incurred in Canadian dollars.


                                                                               9


         For the nine months ended May 31, 2004, selling and administrative
expenses were $19.5 million, or 36.7% of sales, compared to $21.0 million, or
44.0% of sales for the same period last year. As mentioned above, our
restructuring actions combined with tight cost-control measures contributed to
the reduction of our selling and administrative expenses year-over-year.
However, several factors, such as increased commissions on higher sales volume,
a stronger Canadian dollar as well as the recognition of non-cash stock-based
compensation costs of $174,000 prevented us from further reducing our selling
and administrative expenses year-over-year.

         Considering the challenging market conditions, we will continue to
maintain our selling and administrative expenses at an acceptable level without
impeding our efforts to strategically position our company, improve our sales,
and provide quality service to customers. However, any further increase in the
value of the Canadian dollar will negatively affect our selling and
administrative expenses in the upcoming quarter.

RESEARCH AND DEVELOPMENT

         For the three months ended May 31, 2004, gross research and development
expenses totaled $4.2 million, or 20.4% of sales, compared to $4.6 million, or
30.7% of sales for the same period last year. The decrease in our gross research
and development in dollars and as percentage of sales can be explained by
several factors. First, our restructuring actions combined with tight
cost-control measures contributed to the reduction of our gross research and
development expenses year-over-year. In addition, we refocused our research and
development activities in our Photonics and Life Sciences Division based on our
strategy to leverage existing core telecom technologies. Finally, mix and timing
of our research and development projects, especially in our Telecom Division,
caused our gross research and development expenses to decrease year-over-year.
On the other hand, a stronger Canadian dollar, compared to the US dollar,
year-over-year, increased our gross research and development expenses, as most
of these expenses are incurred in Canadian dollars.

         Although we reduced our gross research and development expenses
year-over-year, we still invested significantly in research and development
activities in the third quarter of fiscal 2004, mainly in our Telecom Division,
as we firmly believe that innovation and new product introductions are the key
to gaining market share in the current economic environment and to ensuring the
long-term growth and profitability of the company.

         In the third quarter of fiscal 2004, 21% of sales originated from
products that have been on the market for two years or less. For the third
quarter of 2003, this number reached 48% of sales.

         For the three months ended May 31, 2004, tax credits and grants from
the Canadian federal and provincial governments for research and development
activities were $855,000, or 20.5% of gross research and development expenses,
compared to $1.1 million, or 22.7% of gross research and development expenses
for the same period last year. The decrease in our tax credits and government
grants is mainly related to the decrease in our eligible gross research and
development expenses in Canada, since we were entitled to similar grant programs
and tax credits year-over-year.

         For the nine months ended May 31, 2004, gross research and development
expenses totaled $12.0 million, or 22.6% of sales, compared to $13.3 million, or
27.9% of sales for the


                                                                              10


same period last year. The decrease in gross research and development dollars
and as percentage of sales year-over-year is mostly attributable to our
restructuring efforts as well as tight cost-control measures and the fact that
we refocused our research and development activities in our Photonics and Life
Sciences Division as explained above. However, it should be noted that the
overall decrease in dollar amount was offset in part by the increased value of
the Canadian dollar (compared to the US dollar) year-over-year, since a large
portion of our research and development expenses are denominated in Canadian
dollars.

         For the nine months ended May 31, 2004, tax credits and grants from the
Canadian federal and provincial governments for research and development
activities were $2.4 million, or 19.9% of gross research and development
expenses, compared to $2.9 million, or 21.7% of gross research and development
expenses for the same period last year. The decrease in our tax credits and
government grants is mainly related to the decrease in our eligible gross
research and development expenses in Canada, since we were also entitled to
almost the same grant programs and tax credits year-over-year.

         In the third quarter of fiscal 2003, we wrote off $2.3 million of
Canadian federal tax credits that can be carried forward against future years'
taxable income over the next nine years.

         In the third quarter of fiscal 2004, 21% of our sales originated from
products that have been on the market for two years or less. For the third
quarter of 2003, this number reached 48% of sales. For the nine months ended May
31, 2004, 29% of sales originated from products that have been on the market for
two years or less. The 2004 figures are well below our fiscal 2004 objective of
45%. A higher portion of our sales came from established products, mainly for
FTTP deployments, which caused our percentage of sales of new products to be
lower than expected. With only one quarter left in the year, we won't reach our
objective of 45%. Based on current results and expected sales for the next
quarter, we believe that new-product sales will represent 30% of our sales for
fiscal 2004. However, based on the importance and on the number of products
introduced over the last two years, and so far in fiscal 2004, we still believe
that new products will represent in excess of 40% of our sales in the foreseable
future.

         We expect to continue investing significantly in the research and
development activities of our Telecom Division in the upcoming quarters,
reflecting our focus on innovation, our desire to gain market share and our goal
to exceed customer needs and expectations.

AMORTIZATION OF INTANGIBLE ASSETS

         For the three months and the nine months ended May 31, 2004,
amortization of intangible assets was $1.3 million and $3.8 million,
respectively, compared to $1.5 million and $4.4 million, for the corresponding
periods last year. The decrease in the amortization expense in fiscal 2004
compared to 2003 is the result of the impairment charge recorded in the third
quarter of fiscal 2003.

INTEREST AND OTHER INCOME

         For the three months and nine months ended May 31, 2004, interest and
other income amounted to $398,000 and $1.1 million, respectively, compared to
$379,000 and $929,000 for the corresponding periods last year. During the second
quarter of fiscal 2004, we recorded a one-time revenue of $225,000 for the sale
of a non-core technology to a third party. Without this one-time revenue,
interest and other income would have been relatively flat year-over-year.

         We expect our interest income to increase in upcoming quarters
following our public offering in the second quarter of fiscal 2004.


                                                                              11


FOREIGN EXCHANGE GAIN (LOSS)

         For the three months and nine months ended May 31, 2004, the foreign
exchange gain amounted to $167,000 and $124,000, respectively, compared to a
foreign exchange loss of $600,000 and $1.3 million for the corresponding periods
last year.

         Foreign exchange gains and losses are the result of the translation of
operating activities denominated in currencies other than the Canadian dollar.
During the three months and the nine months ended May 31, 2004, the Canadian
dollar value remained relatively stable resulting in a small foreign exchange
gains during these periods. In contrast, during the three months and the nine
months ended May 31, 2003, the Canadian dollar value increased significantly,
resulting in a significant exchange loss during these periods.

         We manage our exposure to currency risk with forward exchange contracts
and operating activities, denominated in currencies other than the Canadian
dollar, of our Canadian entities.

INCOME TAXES

         For the three months ended May 31, 2004, we recorded a tax recovery of
$135,000. The income tax recovery represents income taxes recoverable in some
specific tax jurisdictions. Since the third quarter of fiscal 2003, we recorded
a full valuation allowance on our future income tax assets because it is more
likely than not that these assets will not be recovered. For the three months
ended May 31, 2003, we recorded a tax expense of $19.3 million, mainly related
to the valuation allowance recorded on our future income tax assets during that
quarter.

         For the nine months ended May 31, 2004, we recorded a tax recovery of
$1.2 million mainly due to the $1.4 million non-recurring income tax recovery
recorded in the first quarter of 2004. This non-recurring gain was due to the
recovery, during that period, of income taxes paid in previous periods following
the receipt of a tax assessment.

LIQUIDITY AND CAPITAL RESOURCES

         We finance our operations and meet our capital expenditure requirements
mainly through cash flows from operating activities, the use of our cash and
short-term investments as well as the issuance of subordinate voting shares.

         During the second quarter of fiscal 2004, pursuant to a public offering
in Canada, we issued 5,200,000 subordinate voting shares for net proceeds of
$29.2 million (Cdn$38.4 million) after deducting underwriting commissions of
$1.2 million (Cdn$1,601,000). These net proceeds will be used for working
capital and other general corporate purposes, including potential acquisitions,
although we currently have no commitments or agreements regarding any
acquisitions. Cash flows provided by financing activities for the nine months
ended May 31, 2004 are attributable to the net proceeds of this offering.

         One of the four main objectives of our strategic plan for fiscal 2004
is to maintain a sound financial position. We believe that such an objective is
in line with a strong cash position and working capital. As at May 31, 2004 cash
and short-term investments consisted of $84.7 million, while our working capital
was at $108.9 million. Our cash and short-term investments decreased $1.1
million compared to February 29, 2004, mainly due the cash payment of $238,000
for the purchase of property, plant and equipment as well as an unrealized
foreign


                                                                              12


exchange loss of $1.4 million on cash and short-term investments. However, the
decrease in cash and short-term investment was offset in part by cash flows from
operating activities of $605,000. The unrealized foreign exchange loss resulted
from the translation in US dollars of our Canadian-dollar-denominated cash and
short-term investments, and was recorded in the cumulative translation
adjustment in the balance sheet. It should be noted that any decline in the
Canadian dollar value compared with the US dollar in future periods will
negatively affect the value of our cash and short-term investments.

         We believe that our cash balances and short-term investments, combined
with an available line of credit of $6.4 million, will be sufficient to meet our
liquidity and capital requirements for the foreseeable future. However, possible
additional operating losses and/or possible investment in or acquisition of
complementary businesses, products or technologies may require additional
financing. There can be no assurance that additional debt or equity financing
will be available when required or, if available, it can be secured on
satisfactory terms. Our line of credit bears interest at prime rate.

OPERATING ACTIVITIES

         Cash flows provided by operating activities were $605,000 for the three
months ended May 31, 2004, compared to cash flows used of $92,000 for the same
period last year. Cash flows provided by operating activities in the third
quarter of fiscal 2004 were mainly attributable to the net earnings after items
not affecting cash of $2.0 million, offset in part by the net increase of our
operating items of $1.4 million; that is, our accounts receivable increased by
$2.4 million and our inventories decreased by $687,000. The increase in our
accounts receivable is directly related to the significant sales growth in the
third quarter of fiscal 2004. On the other hand, the increased sales level
enabled us to reduced our inventories overall.

         Cash flows used by operating activities were $762,000 for the nine
months ended May 31, 2004, compared to cash flows provided of $9.3 million for
the same period last year. Cash flows used by operating activities for the nine
months ended May 31, 2004 were mainly the result of the increase of some of our
operating items; that is, accounts receivable increased by $2.2 million and
income taxes and tax credits recoverable increased by $1.6 million. The increase
in our accounts receivable is directly related to the significant sales growth
in the third quarter of fiscal 2004. The increase in our income taxes and tax
credits recoverable is due to the payment, during the period, of income taxes
payable for previous periods and the recognition of tax credits earned during
the period but not yet recovered. The increase of these two items was offset in
part by the net earnings after items not affecting cash of $3.3 million.

         With positive cash flows from operating activities for the last two
quarters, we met one of our four annual strategic objectives, which consisted in
maintaining a sound financial position.

INVESTING ACTIVITIES

         Cash flows provided by investing activities were $160,000 for the three
months ended May 31, 2004, compared to cash flows used of $1.3 million for the
same period last year. In the third quarter of fiscal 2004, we sold $398,000
worth of short-term investments and paid $238,000 for the purchase of property,
plant and equipment.

         Cash flows used by investing activities amounted to $28.8 million for
the nine months ended May 31, 2004, compared to $13.1 million for the same
period last year. During the second quarter of fiscal 2004, we acquired $28.4
million worth of short-term investments with the net proceeds of the public
offering.


                                                                              13


CONTINGENCY

         As discussed in note 9 to our interim consolidated financial
statements, in November 2001, the company was named as a defendant in a U.S.
securities class action related to its initial public offering (IPO) in June
2000. The complaints allege that the prospectus and the registration statement
for the IPO failed to disclose that the underwriters allegedly received
excessive commissions and that the underwriters and some investors collaborated
in order to inflate the price of EXFO's stock in the aftermarket. Even though
the process is continuing in this class action, we have no significant
developments to report in this quarter.

SHARE CAPITAL AND STOCK-BASED COMPENSATION PLANS

SHARE CAPITAL

         As at May 31, 2004, EXFO had 37,900,000 multiple voting shares
outstanding, entitling to ten votes each and 30,526,108 subordinate voting
shares outstanding. The multiple voting shares and the subordinate voting shares
are unlimited as to number and without par value.

STOCK OPTION PLAN

         The aggregate number of subordinate voting shares covered by options
granted under the stock option plan was 3,124,243 as at May 31, 2004. The
weighted average exercise price of those stock options was $13.69 compared to
the market price of $4.59 per share as at May 28, 2004. The maximum number of
subordinate voting shares issuable under the plan cannot exceed 6,306,153
shares. The following table summarizes information about stock options granted
to the members of the Board of Directors and to Management and Corporate
Officers of the company and its subsidiaries as at May 31, 2004:

RESTRICTED STOCK AWARD PLAN

         In addition to the stock option plan, we maintain a restricted stock
award plan for some U.S.-based employees. The aggregate number of subordinate
voting shares covered by restricted stock awards was 66,654 as at May 31, 2004.
Each restricted stock award entitles employees to receive one subordinate voting
share at a purchase price of nil.


                                                                              14


RISKS AND UNCERTAINTIES

         Over the past few years, we have managed our business, focused on
research and development of new and innovative products, prospered in
international markets and closed strategic acquisitions. However, we operate in
a highly competitive field that is in constant evolution and, as a result, we
encounter various risks and uncertainties that must be given appropriate
consideration in our strategic management policies.

         The main risks and uncertainties related to the telecommunication test
and measurement industry involve the rapid development of new products that have
short life cycles and require extensive research and development; the difficulty
of predicting market size and trends; the difficulty of retaining highly skilled
employees; and the ability to quickly adapt our cost structure to changing
market conditions in order to achieve profitability.

         In addition, given our strategic goals for growth and competitive
positioning in our industry, we are expanding into international markets. This
exposes us to certain risks and uncertainties related to changes in local laws
and regulations, multiple technological standards, protective legislation and
pricing pressure.

         Furthermore, while some strategic acquisitions we have completed are
essential to our long-term growth, they also expose us to certain risks and
uncertainties related to the rapid and effective integration of these businesses
as well as their products, technologies and personnel.

         We are also exposed to currency risks as a result of the export of our
products manufactured in Canada, substantially all of which are denominated in
US dollars. These risks are partially hedged by operating expenses denominated
in US dollars, the purchase of raw materials in US dollars and forward exchange
contracts.

         The economic slowdown in our industry could also result in some of our
customers experiencing difficulties and, consequently, this could have a
negative effect on our results especially in terms of future sales and
recoverability of accounts receivable. However, the sectorial and geographic
diversity of our customer base provides us with a reasonable level of protection
in this area. Finally, other financial instruments, which potentially subject us
to credit risks, consist mainly of cash, short-term investments and forward
exchange contracts. Our short-term investments consist of debt instruments
issued by high-credit quality corporations and trusts. Our cash and forward
exchange contracts are held with or issued by high-credit quality financial
institutions; therefore, we consider the risk of non-performance on these
instruments to be remote.

         For a more complete understanding of risk factors that may affect us,
please refer to the risk factors set forth in our disclosures documents
published with securities commissions.
