                   EXFO REPORTS MODEST SALES GROWTH QUARTER-OVER-QUARTER

        o      SALES INCREASE OF 2% QUARTER-OVER-QUARTER

        o      SALES IMPROVEMENT FOR PORTABLE AND MONITORING PRODUCT LINES OF
               14% FOR THIRD QUARTER OF 2003 COMPARED TO SAME PERIOD IN 2002

        o      STRONG BALANCE SHEET WITH A CASH POSITION OF US$61.8 MILLION

QUEBEC CITY, CANADA, June 26, 2003--EXFO Electro-Optical Engineering Inc.
(NASDAQ: EXFO, TSX: EXF) reported today modest sales growth for the third
quarter ended May 31, 2003 compared to the previous quarter.

Sales increased 2% to US$15.1 million in the third quarter of fiscal 2003 from
US$14.8 million in the second quarter of 2003, but decreased 8% from US$16.3
million in the third quarter of 2002.

"We are pleased that our increased focus on the network service provider (NSP)
market, especially with heightened traction in protocol-layer testing, generated
sales increases for our Portable and Monitoring product lines of 14% for the
third quarter of fiscal 2003 compared to the same period in 2002 and 10% for the
first three quarters of 2003 versus the same time last year," said Germain
Lamonde, Chairman, President and CEO of EXFO. "These sales increases amidst a
shrinking market lead us to believe that we're continuing to gain market share.

"Overall, our net bookings for the first three quarters of fiscal 2003 have been
stable compared to the same period in 2002. However, third-quarter results fell
below our expectations given the lower-than-expected positive seasonal effect on
capital expenditures in the global telecommunications industry, geo-political
and economic uncertainty, the outbreak of SARS as well as significant currency
fluctuations that negatively impacted our operating expenses."

Pro forma net loss* for the third quarter of fiscal 2003 amounted to US$4.1
million, or US$0.06 per share, compared to a pro forma net loss of US$3.4
million, or US$0.05 per share, for the previous quarter and a pro forma net loss
of US$3.9 million, or US$0.06 per share, for the third quarter of 2002.

Net loss for the third quarter of fiscal 2003 totaled US$38.4 million, or
US$0.61 per share, compared to a net loss of US$4.2 million, or US$0.07 per
share, for the second quarter of 2003 and a net loss of US$263.8 million, or
US$4.29 per share, for the third quarter of 2002.

The net loss in the third quarter of fiscal 2003 is largely due to US$35.6
million in impairment of assets, namely US$24.3 million in future income tax
assets, US$4.5 million in goodwill, US$2.9 million in intangible assets, US$2.3
million in R&D tax credits and US$1.6 million in inventories.

Gross margin, excluding the inventory write-off, amounted to 45.6% of sales for
the third quarter of fiscal 2003. Including the inventory write-off, gross
margin dropped to 34.7%.

Tel: (418) 683-0211                                              measurement and

As prescribed by generally accepted accounting principles (GAAP), EXFO reviewed
the carrying value of its assets in the third quarter and determined there was
some impairment. It should be noted, however, that these are one-time, non-cash
charges that do not affect the company's day-to-day operations. EXFO has a
strong balance sheet with a cash position of US$61.8 million to ensure its
long-term growth.

Following the end of the third quarter, EXFO announced a restructuring plan that
will provide approximately US$10 million in annualized pre-tax savings, which
will begin to produce an impact in early fiscal 2004. The company reduced its
workforce by 30%, rationalized its business operations and consolidated some of
its manufacturing operations. These cost-reduction initiatives will incur
charges of approximately US$4.8 million, including US$348,000 in the quarter
ended and substantially all the rest in the fourth quarter.

BUSINESS HIGHLIGHTS

EXFO introduced 10 new products in the third quarter including the 2.5+ Gigabit
Multi-Rate Transceiver for protocol-layer test applications, the Packet
Blazer(TM) Fibre Channel test module for installation and commissioning of
storage area networks, and the Integrated Applications Suite which automates the
operation of test modules within the FTB-400 field-testing platform.

EXFO has turned its business around in the last two years from two-thirds
Industrial and Scientific product lines--mostly with the collapse of the
component manufacturer end-market--to two-thirds Portable and Monitoring product
lines. As part of its restructuring plan, the company also announced that it was
exiting the optical component manufacturing automation business.

OPERATING EXPENSES

Selling and administrative expenses amounted to US$7.7 million, or 50.7% of
sales, in the third quarter of fiscal 2003 compared to US$7.0 million, or 47.7%
of sales, in the second quarter of 2003 and US$8.8 million, or 53.5% of sales,
in the third quarter of 2002.

Gross research and development expenses totaled US$4.6 million, or 30.7% of
sales, in the third quarter of fiscal 2003 compared to US$4.4 million, or 29.9%
of sales, in the previous quarter and US$4.7 million, or 28.9% of sales, in the
third quarter of 2002.

BUSINESS OUTLOOK

EXFO forecasted sales between US$13.0 million and US$16.0 million and a pro
forma net loss* between US$0.04 and US$0.07 per share (GAAP net loss between
US$0.14 and US$0.20 per share) for the fourth quarter of fiscal 2003.

             NOTES TO INTERIM CONSOLIDATED FINANCIAL STATEMENTS

                  (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, 2003, and for the periods ended May
     31, 2002 and 2003, 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 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.


2    NEW ACCOUNTING STANDARDS

     In November 2001, the Canadian Institute of Chartered Accountants (CICA)
     issued section 3870, "Stock-Based Compensation and Other Stock-Based
     Payments", which is effective for fiscal years beginning on or after
     January 1, 2002. The new section applies to awards granted on or after the
     date of adoption, and requires that stock-based payments to non-employees
     and direct awards of stock to employees be accounted for using a fair
     value-based method. The new section also encourages, but does not require,
     the use of a fair value-based method to account for stock-based
     compensation costs arising from awards to employees. The new section
     requires pro forma disclosures with respect to net earnings and net
     earnings per share if a fair value-based method of accounting is not
     adopted for awards granted to employees. The company adopted this new
     standard prospectively on September 1, 2002. The company elected not to
     account for stock-based compensation costs arising from awards to employees
     using the fair value-based method and consequently, the adoption of this
     new standard had no impact on the company's financial results. However, the
     company complied with the standard by providing the required pro forma
     disclosures.

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


     Therefore, if the fair value-based method had been used to account for
     stock-based compensation costs related to stock options granted to
     employees since the adoption of the standard on September 1, 2002, the net
     loss and the related net loss per share figures would be as follows on a
     pro forma basis:

    Net loss per share                                         $          (0.61)     $          (0.71)
    Pro forma net loss per share                               $          (0.61)     $          (0.72)


     These options, which have a weighted average fair value of $0.83, will
     generate aggregate stock-based compensation costs of $1,002,400 over their
     vesting periods. Those costs will be amortized over their vesting periods
     using the graded vesting method resulting in annual stock-based
     compensation costs of $403,500 in 2003, $307,300 in 2004, $190,700 in 2005,
     $91,900 in 2006 and $9,000 in 2007.

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

     The Black-Scholes options valuation model was developed for use in
     estimating the fair value of traded options and awards which have no
     vesting restrictions, and are fully transferable. In addition, option and
     award valuation models require the input of highly subjective assumptions,
     including the expected stock price volatility. Because the company's
     employee stock options have characteristics significantly different from
     those of traded options, and because changes in the subjective input
     assumptions can materially affect the fair value estimate, in management's
     opinion, the existing models do not necessarily provide a reliable single
     measure of the fair value of its employee stock options.

            except share and per share data and as otherwise noted)


     In August 2001, the CICA issued section 3062 "Goodwill and Other Intangible
     Assets", which is effective for fiscal years beginning on or after January
     1, 2002. Section 3062 changes the accounting for goodwill from an
     amortization method to an impairment-only approach. Thus, amortization of
     goodwill, including goodwill recorded in past business combinations ceased
     upon the adoption of this section. For any acquisitions completed after
     June 30, 2001, goodwill is not amortized.

     The company adopted section 3062 prospectively on September 1, 2002. Since
     the adoption of this new section, goodwill recorded prior to July 1, 2001,
     is no longer subject to amortization. Also, under the transitional
     provisions of the section, the company performed an initial impairment test
     in September 2002 to identify goodwill impairment using a fair value-based
     method. Under the new section, a goodwill impairment exists when the
     carrying value of a reporting unit exceeds its fair value. For the purposes
     of the impairment test, the company allocated its existing goodwill to its
     reporting units and completed an evaluation of the fair value of such
     reporting units. Based on the comparison of the fair value of the reporting
     units to their carrying value, goodwill of the reporting units was not
     considered impaired.

     Furthermore, under this new section, goodwill must be tested for impairment
     on an annual basis or more frequently if events or circumstances occur that
     more likely than not reduce the fair value of a reporting unit below its
     carrying value. Any impairment loss arising from this test will be charged
     to earnings in the period in which it is incurred. The company elected to
     perform its annual impairment test in May of each fiscal year for all its
     existing reporting units (note 4).

     This change in accounting policy has been applied prospectively and,
     consequently, the amounts presented for prior periods have not been
     restated. The consolidated statements of earnings for the periods ended May
     31, 2002, show the net loss and the net loss per share figures before the
     amortization of goodwill.

     In November 2002, the CICA issued section 3063 "Impairment of Long-Lived
     Assets", which is effective for fiscal years beginning on or after April 1,
     2003. This new section changes existing rules for recognition and
     measurement of long-lived assets held for use. The section requires that an
     impairment charge be measured as the excess of the carrying value of an
     intangible asset over its fair value. The company adopted this new section
     prospectively on April 1, 2003, and tested its intangible assets under its
     new provisions (note 4).

     In November 2002, the CICA issued section 3475, "Disposal of long-lived
     Assets and Discontinued Operations", which is effective for disposal
     activities initiated by an enterprise's commitment to a plan on or after
     May 1, 2003. Under the new section, a long-lived asset to be disposed of
     other than by a sale continues to be classified as held and used until it
     is disposed of; a long-lived asset classified as held for sale is measured
     at the lower of its carrying value or fair value less cost to sell; a loss
     recognized on classification of long-lived assets as held for sale or a
     group of assets as a discontinued operation does not include future
     operating losses, other than to the extent they are included in the fair
     value of the asset; and discontinued operations are defined more broadly
     than under existing rules. The company adopted this new standard
     prospectively on May 1, 2003, and its adoption had no impact on the
     company's financial statements.

3    BUSINESS COMBINATION

     On October 7, 2002, a newly created wholly-owned subsidiary of the company,
     EXFO Gnubi Products Group Inc. ("EXFO Gnubi"), acquired substantially all
     the assets of GNUBI COMMUNICATIONS, L.P., a U.S. company which supplies
     multi-channel telecom and datacom testing solutions for optical transport
     equipment manufacturers as well as research and development laboratories.
     This acquisition was made to fully complement the company's offering, to
     enhance its competitive position with network service providers and system
     vendors as well as to expand its presence in the data communications test
     market.

     This acquisition was settled for a total consideration valued at $4,663,000
     including acquisition-related costs of $162,000. The consideration paid
     consisted of $1,867,000 in cash, $2,796,000 by the issuance of 1,479,290
     subordinate voting shares and a cash contingent consideration up to a
     maximum of $2,900,000, based on sales volume of EXFO Gnubi for the twelve
     months following the acquisition.

     The cash contingent consideration to be paid upon the realization of the
     defined sales volume is accounted for as additional acquisition cost and is
     recognized as additional cost of acquired core technology as sales occur.
     Since October 7, 2002, the company recognized $155,000 as additional cost
     of acquired core technology based on realized sales of EXFO Gnubi.

     The fair value of the subordinate voting shares issued was determined based
     on the market price of the shares beginning three days before and ending
     three days after the number of shares became fixed based on a formula; that
     is, September 10, 2002.

     This acquisition has been accounted for using the purchase method and,
     consequently, the results of operations of the acquired business have been
     included in the consolidated statement of earnings of the company since
     October 7, 2002; i.e., the date of acquisition.

     The purchase price, including acquisition-related costs, has been allocated
     based on the estimated fair value of net assets at the date of acquisition
     as follows:


                                                                   (UNAUDITED)

     Core technology, which represents the existing technology that has reached
     technological feasibility, is amortized on a straight-line basis over its
     estimated useful life of five years. Goodwill, which will be fully
     deductible for income tax purposes, is not amortized but is reviewed for
     impairment on an annual basis or more frequently if events or circumstances
     occur that more likely than not reduce the fair value of EXFO Gnubi below
     its carrying value.


4    SPECIAL CHARGES

     WRITE-DOWN OF GOODWILL AND INTANGIBLE ASSETS

     In May 2003, the company performed its annual impairment test on goodwill
     for all its reporting units, except for newly acquired EXFO Gnubi. Also,
     considering current market conditions in the telecommunications industry
     and the persisting unfavorable conditions affecting the subsidiaries'
     industry, the company reviewed the carrying value of intangible assets
     related to these reporting units.

     As a result of this assessment, the company concluded that the carrying
     value of goodwill related to EXFO Burleigh and the carrying value of
     intangible assets related to EXFO Burleigh and EXFO Photonic Solutions was
     impaired and it recorded a charge of $4,505,000 to write down goodwill and
     a pre-tax charge of $2,922,000 to write down core technology. Of the total
     impairment charge, $6,872,000 related to EXFO Burleigh for goodwill and
     core technology and $555,000 relates to EXFO Photonic Solutions for core
     technology.


     RESTRUCTURING AND OTHER CHARGES AND INVENTORY WRITE-OFFS

     In November 2001, the company incurred restructuring charges to reduce
     costs and increase efficiency. The company recorded $410,000 in severance
     expenses for the 101 employees who were terminated, which are included in
     the restructuring and other charges in the statement of earnings for the
     nine months ended May 31, 2002. The company also recorded $3,500,000 in
     inventory write-offs for excess and obsolete inventories, which are
     included in the cost of sales in the statement of earnings for that same
     period.

     In February 2002, the company incurred additional restructuring charges in
     order to align its cost structure to market conditions. The company
     recorded $447,000 in severance expenses for the additional 57 employees who
     were terminated, which are included in the restructuring and other charges
     in the statement of earnings for the nine months ended May 31, 2002. The
     company also recorded $5,862,000 in additional inventory write-offs for
     excess and obsolete inventories, which is included in the cost of sales in
     the statement of earnings for that same period.

     In May 2002, the company incurred additional charges to further reduce its
     costs. Under an additional structured plan, the company recorded $1,155,000
     in severance expenses for the additional 192 employees who were terminated
     and $868,000 for the write-off of property plant and equipment. These
     charges are included in the restructuring and other charges in statements
     of earnings for the periods ended May 31, 2002. The company also recorded
     $9,101,000 in additional inventory write-offs for excess and obsolete
     inventories, which is included in the cost of sales for these same periods.

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


     In May 2003, the company implemented an additional restructuring plan to
     realign its cost structure to current market conditions. The first part of
     this plan, which was effective in May, resulted in 13 employees being
     terminated and severance expenses of $348,000 recorded in the restructuring
     and other charges in the statements of earnings for the periods ended May
     31, 2003. The second part of this plan, which will occur mainly in the
     fourth quarter of 2003, will reduce its workforce by 30% overall and
     related restructuring and other charges will be recorded as incurred.

     Furthermore, in May 2003, the company recorded $1,646,000 in inventory
     write-offs for excess and obsolete inventories, which is included in the
     cost of sales in the statements of earnings for the periods ended May 31,
     2003.

     As at May 31, 2003, accrued liabilities for these and past plans amounted
     to $312,000.


     FUTURE INCOME TAX ASSETS AND RESEARCH AND DEVELOPMENT TAX CREDITS

     In May 31, 2003, the company reviewed the carrying value of its future
     income tax assets and its research and development tax credits. Considering
     current market conditions and because the company recorded losses for
     current and past fiscal years, it concluded that it is more likely than not
     that some of its future income tax assets and research and development tax
     credits will not be recoverable and that a valuation allowance and
     write-off were required. Accordingly, the company recorded a valuation
     allowance of $24,260,000 to write off most of its future income tax assets
     mainly related to the parent company, EXFO Protocol and EXFO Burleigh and
     wrote off $2,297,000 in research and development tax credits related to
     EXFO Protocol. The valuation allowance was recorded in the income tax
     expense in the statements of earnings for the periods ended May 31, 2003,
     and the write-off of research and development tax credits was recorded in
     the net research and development expenses in the statements of earnings for
     these same periods.

     From the $24,260,000 valuation allowance for future income tax assets,
     $12,120,000 represent tax assets that can be carried forward indefinitely
     against future years taxable income, while $12,140,000 represent tax assets
     that can be carried forward against future years taxable income mainly over
     the next seven years. All tax credits written off can be carried forward
     indefinitely against future years taxable 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.

     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 Telling Agreements entered into with the plaintiffs.

     Management believes that the company and its executive officers have fully
     complied with all applicable securities laws and that the claims against it
     are without merit. The company has referred this matter to its insurers and
     is vigorously defending its position in this litigation. However, at this
     time, it is not possible to predict the final outcome of this case, nor
     determine the amount of possible losses. Accordingly, no provision for this
     case has been made in the consolidated financial statements as of May 31,
     2003.

          calculation of diluted loss per
          share because their exercise
          price was greater than the

     The diluted loss per share for the periods ended May 31, 2002 and 2003, 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.

     NEW ACCOUNTING STANDARDS

     In July 2001, the Financial Accounting Standard Board (FASB) issued SFAS
     142 "Goodwill and Other Intangible Assets", which is effective for fiscal
     years beginning on or after January 1, 2002. SFAS 142 changes the
     accounting for goodwill from an amortization method to an impairment-only
     approach. Thus, amortization of goodwill, including goodwill recorded in
     past business combinations, ceased upon the adoption of this statement. For
     any acquisitions completed after June 30, 2001, goodwill is not amortized.
     The company adopted SFAS 142 prospectively on September 1, 2002. Since the
     adoption of this new statement, goodwill recorded prior to July 1, 2001, is
     no longer subject to amortization. Also, under the transitional provisions
     of SFAS 142, the company performed an initial impairment test to identify
     goodwill impairment using a fair value-based method. Under SFAS 142, a
     goodwill impairment exists when the carrying value of a reporting unit
     exceeds its fair value. For the purposes of the impairment test, the
     company allocated its existing goodwill to its reporting units and
     completed an evaluation of the fair value of such reporting units. Based on
     the comparison of the fair value of the reporting units to their carrying
     value, goodwill of the reporting units was not considered impaired.

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


     Goodwill is also tested for impairment on an annual basis or more
     frequently if events or circumstances occur that more likely than not
     reduce the fair value of a reporting unit below its carrying value. Any
     impairment loss arising from this test will be charged to earnings in the
     period in which it is incurred. The company elected to perform its annual
     impairment test in May of each fiscal year for all its existing reporting
     units.

     The following table summarizes the impact of this change in accounting
     policy on the net loss and the net loss per share for the comparative
     previous periods on a pro forma basis:

     In June 2001, the FASB issued SFAS 143, "Accounting for Asset Retirement
     Obligation", which is effective for fiscal years beginning on or after June
     15, 2002. This standard requires that the fair value of a liability for an
     asset retirement obligation be recognized in the period in which it is
     incurred if a reasonable estimate of fair value can be made. The company
     adopted this new standard prospectively on September 1, 2002, and its
     adoption had no impact on the company's financial statements.

     In October 2001, the FASB issued SFAS 144, "Accounting for Impairment or
     Disposal of Long-Lived Assets", which supersedes SFAS 121 and the
     provisions of APB 30, "Reporting the Results of Operations - Reporting the
     Effects of Disposal of a Segment of a Business, and Extraordinary, Unusual
     and Infrequently Occurring Events and Transactions" with regard to
     reporting the effects of a disposal of a segment of a business. SFAS 144
     retains many of the provisions of SFAS 121, but significantly changes the
     criteria that would have to be met to classify an asset as held for
     disposal such that long-lived assets to be disposed of other than by sale
     are considered held and used until disposed of. In addition, SFAS 144
     retains the basic provisions of APB 30 for presentation of discontinued
     operations in the statement of earnings but broadens that presentation to a
     component of an entity. This new standard is effective for fiscal years
     beginning on or after December 15, 2001. The company adopted this new
     standard prospectively on September 1, 2002, and its adoption had no impact
     on the company's financial statements.

     In April 2002, the FASB issued SFAS 145, "Rescission of FASB Statements No.
     4, 44 and 64, Amendment of FASB Statement No. 13 and Technical
     Corrections". This new standard is effective for fiscal years beginning on
     or after May 15, 2002, or for transactions occurring after May 15, 2002,
     related to SFAS 13, paragraph 8 and 9 (c). This statement rescinds SFAS 4
     "Reporting Gains and Losses from Extinguishment of Debt" and an amendment
     of that Statement, SFAS 64,

             NOTES TO INTERIM CONSOLIDATED FINANCIAL STATEMENTS

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


     "Extinguishments of Debt Made to Satisfy Sinking-Funds Requirements". This
     Statement also rescinds SFAS 44 "Accounting for Intangible Assets of Motor
     Carriers". This Statement amends SFAS 13 "Accounting for Leases" to
     eliminate an inconsistency between the required accounting for
     sale-leaseback transactions. This Statement also amends other existing
     authoritative pronouncements to make various technical corrections, clarify
     meanings, or describe their applicability under changed conditions. The
     company adopted this new standard prospectively on September 1, 2002, and
     its adoption had no impact on the company's financial statements.

     In June 2002, the FASB issued SFAS 146, "Accounting for Costs Associated
     with Exit or Disposal Activities". This Statement addresses financial
     accounting and reporting for costs associated with exit or disposal
     activities and nullifies EITF No. 94-3, "Liability Recognition of Certain
     Employee Termination Benefits and Other Costs to Exit an Activity". This
     Statement improves financial reporting by requiring that a liability for a
     cost associated with an exit or disposal activity be recognized and
     measured initially at fair value only when the liability is incurred. This
     Statement specifies that a liability for a cost associated with an exit or
     disposal activity is incurred when the definition of a liability in SFAS 6
     is met. This Statement is effective for exit or disposal activities that
     are initiated after December 31, 2002. The company adopted this new
     standard prospectively on January 1, 2003, and its adoption had no impact
     on the company's financial statements.

     In November 2002, the FASB issued FIN 45, "Guarantor's Accounting and
     Disclosure Requirements for Guarantees, Including Indirect Guarantees of
     Indebtedness of Others, an interpretation of FASB Statements No. 5, 57 and
     107 and Rescission of FASB Interpretation No. 34", with disclosure
     requirements effective for periods ending after December 15, 2002 and
     recognition and measurement requirements effective on a prospective basis
     for guarantees that are issued or modified after December 31, 2002.

     FIN 45 provides a definition and examples of a guarantee and requires
     disclosure of the nature of the guarantee, the maximum potential amount of
     future payments, the carrying amount of the related liability, if any, the
     recourse provisions and assets held as collateral under the terms of the
     guarantee and the extent to which the proceeds of collateral would cover
     the maximum potential liability.

     It also clarifies the requirement of SFAS 5, "Accounting for
     Contingencies", relating to the guarantor's accounting for, and disclosure
     of, the issuance of certain types of guarantees. It requires that the
     guarantor recognize a liability for the guarantee at its inception equal to
     its fair value at that time and that the liability is reduced as the risk
     under the guarantee reduces. The liability may be reduced at the end of the
     guarantee period, on a systematic amortization basis or as the fair value
     changes as appropriate.

     The company has adopted the disclosure requirements of FIN 45 for the
     periods ended May 31, 2003.

     In December 2002, the FASB issued Statement 148, "Accounting for
     Stock-Based Compensation - Transition and Disclosure", revising the
     transition and disclosure provisions of SFAS 123. SFAS 148 allows companies
     to adopt SFAS 123 under three different methods. In addition, SFAS 148
     requires increased disclosure for all companies, including those choosing
     not to adopt the accounting provision of SFAS 123. The transition and
     disclosure changes are effective for fiscal years ending after December 15,
     2002. The company will disclose the information required in its annual
     financial statements.

            except share and per share data and as otherwise noted)


     In January 2003, the FASB issued FIN 46, "Consolidation of Variable
     Interest Entities - an Interpretation of ARB No. 51." The primary
     objectives of FIN 46 are to provide guidance on the identification of
     entities for which control is achieved through means other than through
     voting rights and how to determine when and which business enterprise
     should consolidate the variable interest entities. This interpretation
     applies immediately to variable interest entities created after January 31,
     2003, and to variable interest entities in which an enterprise obtains an
     interest after that date. It applies in the first quarter beginning after
     June 15, 2003, to variable interest entities in which an enterprise holds a
     variable interest it acquired before February 1, 2003. The company does not
     hold variable interest entities; consequently, the adoption of this new
     standard had no impact on the company's financial statements.

     In April 2003, the FASB issued SFAS 149, "Amendment of Statement 133 on
     Derivative Instruments and Hedging Activities". The statement amends and
     clarifies accounting for derivatives instruments, including certain
     derivative instruments embedded in other contracts, and for hedging
     activities under SFAS 133. The amendments set forth in Statement 149
     improve financial reporting by requiring that contracts with comparable
     characteristics be accounted for similarly. In particular, this Statement
     clarifies under what circumstances a contract with an initial net
     investment meets the characteristics of a derivative as discussed in
     Statement 133. In addition, it clarifies when a derivative contains a
     financing component that warrants special reporting in the statement of
     cash flows. Statement 149 amends certain other existing pronouncements.
     This statement is effective for contracts entered into or modified after
     June 30, 2003, and for hedging relationships designated after June 30,
     2003. The company will adopt this new standard prospectively on June 30,
     2003, and its adoption will have no impact on the company's financial
     statements.

     In May 2003, the FASB issued SFAS 150, "Accounting for Certain Financial
     Instruments with Characteristics of both Liabilities and Equity". The
     statement improves the accounting for certain financial instruments such as
     mandatorily redeemable preferred shares that, under previous guidance,
     issuers could account for as equity. The new Statement requires that those
     instruments be classified as liabilities in statements of financial
     position. In addition to its requirements for the classification and
     measurement of financial instruments in its scope, this statement also
     requires disclosures about alternative ways of settling the instruments and
     the capital structure of entities, all of whose shares are mandatorily
     redeemable. Most of the guidance provided in this statement is effective
     for all financial instruments entered into or modified after May 31, 2003,
     and otherwise is effective at the beginning of the first interim period
     beginning after June 15, 2003. The company will adopt this new standard
     prospectively on June 1, 2003, and its adoption will have no impact on the
     company's financial statements.

OVERVIEW

         Fiber-optic telecommunications companies, still dealing with reduced
spending levels, were affected by a number of external forces during the past
quarter including geo-political and economic uncertainty, the outbreak of SARS
in Asia, as well as the declining strength of the U.S. dollar. To cope with
market realities, network service providers (NSPs), the first link in the
fiber-optic telecom supply chain, continued to service their debt-loads and
preserve cash. Moreover, as capital expenditure (CAPEX) budgets increasingly
drew nearer to maintenance-level run rates, NSPs turned their attention to
operating expenditures (OPEX) for further savings. As a result, there is little
evidence of an imminent recovery in the global fiber-optic telecom industry.

         Lower spending levels necessarily produced a trickle-down effect
throughout the fiber-optic telecom industry; namely, for optical system and
component manufacturers as well as for test, measurement, and monitoring
equipment vendors. System manufacturers were negatively affected by the
significant reduction in the deployment of long-haul optical networks, but


                                                                               1



benefited from some activity in metro and access networks. Optical component
manufacturers were hardest hit by the downturn, given their position in the
supply chain, relative stability of technology and excess manufacturing capacity
in this sector. The ongoing consolidation within the optical component
manufacturing market provides an inkling of its weaker health.

         Test, measurement and monitoring equipment vendors also felt the impact
of reduced NSP spending with less demand for orders. In addition, distressed
vendors increasingly applied pricing pressure to obtain contracts, which eroded
margins across the board. The grey market for test and measurement instruments,
especially involving optical component manufacturing applications, further
compounded the soft market. On the other hand, test, measurement and monitoring
vendors, whose products enable customers to lower OPEX, still attracted the
attention of NSPs and system manufacturers for certain projects.

         Against this backdrop, EXFO adopted a two-fold approach in order to
return to profitability: increase sales and reduce costs. To increase our sales,
we deployed efforts to gain market share, especially in the NSP market. We also
further leveraged our acquisitions of Avantas Networks and gnubi communications
to heighten traction in the protocol-layer test sector. In addition, we
maintained our focus on innovation with the introduction of 10 new products
during the last quarter including the 2.5+ Gigabit Multi-Rate Transceiver for
protocol-layer test applications, the Packet Blazer Fiber Channel test module
for installation and commissioning of storage area networks, and the Integrated
Applications Suite, which automates the operation of test modules within the
FTB-400 field-testing platform. A common characteristic of these products is
that it helps customers lower their OPEX. Our strategy has proven to be on
target with a 10% increase in sales for our Portable and Monitoring product
lines during the first three quarters of fiscal 2003 versus the same period last
year.

         Although we undertook several steps to bolster our top line during this
unprecedented market downturn -- gain market share, leverage our protocol-layer
test acquisitions and introduce new products -- it wasn't enough due to
continued depressed spending levels in the global fiber-optic telecom industry
and the aforementioned external forces.

         With no signs of an imminent market recovery, we announced a major
restructuring plan following the end of the third quarter. We reduced our
workforce by 30%, exited the optical component manufacturing automation business
and consolidated some of our manufacturing operations. The restructuring plan is
expected to provide us with approximately $10 million in annualized pre-tax
savings. Conversely, it will incur charges of approximately $4.8 million,
including $348,000 in the quarter ended and substantially all the rest in the
fourth quarter.

         During the second quarter of 2003, we launched the FTB-5500B
Polarization Mode Dispersion (PMD) Analyzer, an essential test instrument for
upgrading optical networks to 10 Gb/s and deploying a cascade of amplifiers.
This patent-pending PMD Analyzer represents the only portable instrument that
can characterize PMD levels in a network by sweeping through erbium-doped fiber
amplifiers (EDFAs). Our PMD Analyzer can test an entire link with the utmost
accuracy and repeatability in less than five seconds.

         In October 2002, we completed, through our newly created wholly-owned
subsidiary EXFO Gnubi Products Group Inc., the acquisition of substantially all
the assets of GNUBI COMMUNICATIONS, L.P., a multi-channel telecom and datacom
testing solutions supplier with an established customer base of Tier-1 system
vendors and research and development laboratories. This acquisition was made to
fully complement our offering, to enhance our competitive position with network
service providers and system vendors as well as to expand


                                                                               2



our presence in the data communications test market. This acquisition was
settled for a total consideration of $4.7 million. The consideration paid
consisted in $1.9 million in cash, $2.8 million by the issuance of 1.5 million
subordinate voting shares and a cash contingent consideration up to a maximum of
$2.9 million, based on sales volume for the twelve months following the
acquisition. This acquisition has been accounted for using the purchase method
and resulted in goodwill of $3.0 million.

         During the first quarter of 2003, we reached a base of more than 10,000
test platforms on the global market. We also launched two new products,
including the FTB-9310 Channel Selector, for commissioning and lighting channels
in dense wavelength-division multiplexing (DWDM) networks, and the X-Cite 120
Illumination System, for fluorescence microscopy applications.


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 securities commissions. The following
details the changes in critical accounting policies that occurred since our most
recent annual report.

         IMPAIRMENT OF GOODWILL AND INTANGIBLE ASSETS. We assess impairment of
goodwill on an annual basis or more frequently if events or circumstances occur
that more likely than not reduce the fair value of a reporting unit below its
carrying value. Goodwill impairment exists when the carrying value of a
reporting unit exceeds its fair value. The amount of impairment loss, if any, is
the excess of the carrying value of goodwill over its fair value. On September
1, 2002, upon the adoption of section 3062 of the Canadian Institute of
Chartered Accountants Handbook (CICA) `'Goodwill and Other Intangible Assets",
we performed an initial impairment test of goodwill based on a fair value
method. For the purposes of this test, we allocated our existing goodwill to our
reporting units and completed an evaluation of the fair value of such reporting
units. For the purposes of this evaluation, we used discounted future cash flows
as well as multiple of sales to estimate the fair value of each reporting unit.
The assumptions used reflect our best estimates. Based on the comparison of the
fair value of the reporting units to their carrying value, goodwill was not
considered impaired at that moment.

         Furthermore, we assess impairment of intangible assets when events or
circumstances indicate that costs may not be recoverable. Impairment exists when
the carrying value of the asset is greater than the pre-tax undiscounted future
cash flows expected to be provided by the asset. The amount of impairment loss,
if any, is the excess of the carrying value over its fair value. We assess fair
value of intangible assets based on discounted future cash flows.

         In May 2003, we assessed impairment of goodwill and intangible assets
based on these new standards. Please refer to the `'Write-down of goodwill and
intangible assets" section further in this document.



                                                                               3

SALES

         For the three months ended May 31, 2003, sales decreased 7.6% to $15.1
million from $16.3 million for the same period last year. The decrease in our
sales in the third quarter of 2003 is mainly related to the continued slowdown
in the telecommunications industry and the increase pricing pressure by vendors,
which inevitably reduced our top line. Despite the acquisition of EXFO Gnubi, we
were not able to maintain our sales level quarter over quarter.

         Fiber-optic telecommunications companies, still dealing with reduced
spending levels, were affected by a number of external forces during the past
quarter including geo-political and economic uncertainty, the outbreak of SARS
in Asia, as well as the declining strength of the U.S. dollar. To cope with
market realities, network service providers (NSPs), the first link in the
fiber-optic telecom supply chain, continued to service their debt-loads and
conserve cash. Moreover, as capital expenditure (CAPEX) budgets increasingly
drew nearer to maintenance- level run rates, NSPs turned their attention to
operating expenditures (OPEX) for further savings. As a result, there is little
evidence of an imminent recovery in the global fiber-optic telecom industry.

         Lower spending levels necessarily produced a trickle-down effect
throughout the fiber-optic telecom industry; namely, for optical system and
component manufacturers as well as for test, measurement, and monitoring
equipment vendors. System manufacturers were negatively affected by the
significant reduction in the deployment of long-haul optical networks, but
benefited from some activity in metro and access networks. Optical component
manufacturers were hardest hit by the downturn, given their position in the
supply chain, relative stability of technology and excess manufacturing capacity
in this sector. The ongoing consolidation within the optical component
manufacturing market provides an inkling of its weaker health.

         Test, measurement and monitoring equipment vendors also felt the impact
of reduced NSP spending with less demand for orders. In addition, distressed
vendors increasingly applied pricing pressure to obtain contracts, which eroded
margins across the board. The grey market for test and measurement instruments,
especially involving optical component manufacturing applications, further
compounded the soft market. On the other hand, test, measurement and monitoring
vendors, whose products enable customers to lower OPEX, still attracted the
attention of NSPs and system manufacturers for certain projects.

         With regard to sales distribution, it was a 66%-34% split in favor of
our Portable and Monitoring products for the three months ended May 31, 2003,
compared to 53%-47% for the same period last year. We expect the sales split to
be in the same range in upcoming quarters, given the state of the
telecommunications industry.

         Net accepted orders decreased 9.6% to $14.1 million in the third
quarter of 2003 from $15.6 million for the same period last year. Our net
book-to-bill ratio decreased to 0.93 in the third quarter of 2003, compared to
0.95 for the same period last year.

         North American sales accounted for 59% and 51% of global sales for the
three months ended May 31, 2003 and 2002, respectively. International sales
represented 41% and 49% of global sales for the three months ended May 31, 2003
and 2002, respectively. The decrease in our international sales quarter over
quarter is mainly due to the decrease in our sales to the Asian market. Most of
our sales in this market are made through tenders, which may vary in number and
significance from quarter to quarter. In addition, the SARS outbreak also
affected our sales in Asia to some extent.


                                                                               6



         We sell our products to a broad range of customers including
telecommunications carriers, network service providers, optical component and
system manufacturers, as well as research and development laboratories. For the
three months ended May 31, 2003, we had two customers accounting for more than
10%, with our top three customers representing 25.9% of our sales. For the three
months ended May 31, 2002, no customer accounted for more than 7.8% of our
sales.

         For the nine months ended May 31, 2003, sales decreased 6.7% to $47.6
million from $51.1 million for the same period last year. The decrease in sales
for the nine months ended May 31, 2003, is mainly related to the continued
slowdown in the telecommunications industry and the increased pricing pressure
by distressed vendors, which inevitably reduced our top line. Despite the
acquisitions of EXFO Protocol and EXFO Gnubi, we were not able to maintain our
sales level year over year.

         With regard to sales distribution, it was a 66%-34% split in favor of
our Portable and Monitoring products for the nine months ended May 31, 2003,
compared to 56%-44% in favor of our Portable and Monitoring products for the
same period last year.

         North American sales accounted for 57% and 52% of global sales for the
nine months ended May 31, 2003, and 2002, respectively. International sales
represented 43% and 48% of global sales for the nine months ended May 31, 2003
and 2002, respectively. The shift in the geographic distribution of our sales is
due to the decrease in sales to the Asian market, where most of our sales are
made through tenders, which may vary in number and significance from period to
period. In addition, the SARS outbreak also affected our sales in Asia to some
extent.

         For the nine months ended May 31, 2003, no customer accounted for more
than 9.5% of our sales, with our top three customers representing 19.4% of our
sales. For the nine months ended May 31, 2002, no customer accounted for more
than 6.5% of our sales.


GROSS MARGIN (LOSS)

         Gross margin amounted to 34.7% of sales for the three months ended May
31, 2003, compared to a gross loss of 4.5% for the same period last year.

         For the three months ended May 31, 2003 and 2002, we recorded
write-offs for excess and obsolete inventories of $1.6 million and $9.1 million,
respectively. These special charges were required considering our expected needs
for the next 12 to 24 months and our exit from the automation business. Without
these special charges, gross margin would have reached 45.6% and 51.2% of sales
for these two periods, respectively. The percentage decrease quarter over
quarter is due to the following reasons. First, current market conditions and
the competitive landscape inevitably led to increased pricing pressure. Combined
with a lower sales level in the third quarter of 2003, this prevented a better
absorption of our fixed manufacturing costs, which ultimately caused margin
erosion. Also, shift in product mix caused our gross margin to decrease. Our
Portable and Monitoring products represented a larger portion of our sales in
the third quarter of 2003, compared to the same period last year; these products
tend to be lower-margin products. However, the decrease in our gross margin was
offset in part by our restructuring efforts implemented in 2002 and our
increased efficiency, as well as the shift in the geographic distribution of our
sales. In the third quarter of 2003, this shift resulted in more sales in North
America, where gross margins tend to be higher, and less sales made
internationally, where gross margins tend to be lower.


                                                                               7



         Gross margin amounted to 47.3% of sales for the nine months ended May
31, 2003, compared to 16.8% for the same period last year.

         For the nine months ended May 31, 2003 and 2002, we recorded write-offs
for excess and obsolete inventories of $1.6 million and $18.5 million,
respectively. As mentioned above, these special charges were required
considering our expected needs for the next 12 to 24 months and our exit from
the automation business. Without these special charges, gross margin would have
reached 50.8% and 53.0% of sales for these two periods, respectively. The
percentage decrease year over year is due the following reasons. First, current
market conditions and the competitive landscape inevitably led to increased
pricing pressure. Combined with a lower sales level in the first three quarters
of 2003, this prevented a better absorption of our fixed manufacturing costs,
which ultimately caused margin erosion. Also, shift in product mix caused our
gross margin to decrease. Our Portable and Monitoring products represented a
larger portion of our sales for the nine months ended May 31, 2003, compared to
the same period last year; these products tend to be lower-margin products.
However, the decrease in our gross margin was offset in part by our
restructuring efforts implemented in 2002 and our increased efficiency, as well
as the shift in the geographic distribution of our sales. For the nine months
ended May 31, 2003, this shift resulted in more sales in North America, where
gross margins tend to be higher, and less sales made internationally, where
gross margins tend to be lower.

         We expect our gross margin to fluctuate in the upcoming quarters as our
sales may fluctuate. 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 the fiber-optic test, measurement and monitoring
industry.


SELLING AND ADMINISTRATIVE

         For the three months ended May 31, 2003, selling and administrative
expenses were $7.7 million, or 50.7% of sales, compared to $8.8 million, or
53.5% of sales for the same period last year. The dollar decrease is mainly
related to lower expenses resulting from our restructuring plans, mainly
implemented during the second and the third quarter of 2002 and lower commission
expenses since our sales decreased quarter over quarter. However, this decrease
was offset in part by the impact of the acquisition of EXFO Gnubi in October
2002. Overall, despite the acquisition EXFO Gnubi, we were able to reduce our
selling and administrative expenses by more than $1 million, mainly because of
our recent restructuring efforts and our cost-control measures.

         For the nine months ended May 31, 2003, selling and administrative
expenses were $22.3 million, or 47.1% of sales, compared to $28.3 million, or
55.4% of sales for the same period last year. The dollar decrease is directly
related to lower expenses resulting from our restructuring plans, mainly
implemented during the second and the third quarter of 2002 and from lower
commission expenses since our sales decreased year over year. However, this
decrease was offset in part by the impact of the acquisitions of EXFO Protocol
and EXFO Gnubi in November 2001 and October 2002, respectively. Overall, despite
the decrease in sales for the nine months ended May 31, 2003, compared to the
same period last year and the effects of the acquisitions of EXFO Protocol and
EXFO Gnubi, we were able to reduce our selling and administrative expenses by
more than $6.0 million, mainly because of our recent restructuring efforts and
our cost control measures.


                                                                               8



         In June 2003, we announced additional cost-cutting measures that should
enable us to reduce our selling and administrative expenses as a percentage of
sales in upcoming quarters.

         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,
as well as provide quality service to customers and integrate our acquired
businesses.


RESEARCH AND DEVELOPMENT

         For the three months ended May 31, 2003, gross research and development
expenses totaled $4.6 million, or 30.7% of sales, compared to $4.7 million, or
28.9% of sales for the same period last year. The decrease in gross research and
development dollars quarter over quarter is due to the effects of our recent
restructuring actions mainly offset by the effects of the acquisition of EXFO
Gnubi, which carried out research and development activities. The percentage
increase can be explained by the fact that despite challenging market
conditions, we continue investing heavily in research and development, which
reflects our strong focus on innovation. We firmly believe that innovation and
new product introductions are the key to gaining market share in this current
economic environment and ensuring the long-term growth and profitability of the
company. In the third quarter of 2003, 48% of sales originated from products
that have been on the market for two years or less.

         For the three months ended May 31, 2003, tax credits and grants from
federal and provincial governments for research and development activities were
$1.1 million, or 22.7% of gross research and development expenses, compared to
$1.3 million, or 26.9% of gross research and development expenses for the same
period last year. The decrease in our tax credits and grants, in dollar amounts,
is mainly related to the end of certain government grant programs and the
decrease in our gross research and development expenses. The primary reasons for
the percentage decrease are the end of certain government grant programs and the
recent acquisition of U.S.-based EXFO Gnubi, as we carried out more research and
development activities in the U.S., where such activities are not eligible for
tax credits.

         In the third quarter of 2003, we wrote off $2.3 million of Canadian
federal tax credits for EXFO Protocol and will not record such credits for EXFO
Protocol in the fourth quarter of 2003. Considering current and past year tax
losses as well as current market conditions, we concluded (according to GAAP)
that it was more likely than not that those tax credits will not be recovered
and that a write-off was required. All tax credits written off can be carried
forward indefinitely against future taxable income.

         As for net research and development expenses, they amounted to 38.9%
and 21.1% of sales for the three months ended May 31, 2003 and 2002,
respectively. This large increase is mainly due to the write-off of research and
development tax credits. Although we intend to reduce our research and
development expenses as a percentage of sales in the future and despite our
recently announced cost-cutting measures, we expect to continue investing
significantly in research and development in the next year, reflecting our focus
on innovation, our desire to gain market share and our goal to exceed customer
needs and expectations. However, we expect our net research and development
expenses to be reduced, as we will not record Canadian federal tax credits for
EXFO Protocol in the fourth quarter.


                                                                               9



         For the nine months ended May 31, 2003, gross research and development
expenses totaled $13.3 million, or 27.9% of sales, compared to $13.8 million, or
26.9% of sales for the same period last year. The slight decrease in gross
research and development dollars year over year is due to the effects of our
recent restructuring actions, mostly offset by the effects of the acquisitions
of EXFO Protocol and EXFO Gnubi, which carried out a significant level of our
research and development activities. The percentage increase can be explained by
the fact that despite challenging market conditions, we continue investing
heavily in research and development, which reflects our strong focus on
innovation despite the decrease in sales. For the nine months ended May 31, 2002
and 2003, 50% of sales originated from products that have been on the market for
two years or less.

         For the nine months ended May 31, 2003, tax credits and grants from
federal and provincial governments for research and development activities were
$3.0 million, or 22.9% of gross research and development expenses, compared to
$3.5 million, or 25.3% of gross research and development expenses for the same
period last year. The decrease in our tax credits and grants, in dollar amounts,
is mainly related to the end of certain government grant programs and the slight
decrease in our gross research and development expenses. The primary reasons for
the percentage decrease are the end of certain government grant programs and the
recent acquisition of U.S.-based EXFO Gnubi, as we carried out more research and
development activities in the U.S., where such activities are not eligible for
tax credits.

         During the nine months ended May 31, 2003, we wrote off $2.3 million of
Canadian federal tax credits for EXFO Protocol and will not record such credits
for EXFO Protocol in the fourth quarter of 2003. Considering current and past
year tax losses as well as current market conditions, we concluded according to
GAAP that it was more likely than not that those tax credits will not be
recovered and that a write-off was required.

         As for net research and development expenses, they amounted to 26.3%
and 20.1% of sales for the nine months ended May 31, 2003 and 2002,
respectively.


AMORTIZATION OF INTANGIBLE ASSETS

         In conjunction with the four strategic acquisitions that we made over
the last two fiscal years and in the first quarter of 2003, we recorded $62
million in intangible assets, primarily consisting of core technology. These
intangible assets, which are amortized over periods from five months to five
years from the date of acquisitions, resulted in amortization expenses of $1.3
million and $3.2 million for the three months ended May 31, 2003 and 2002,
respectively, and of $3.7 million and $10.0 million for the nine months ended
May 31, 2003 and 2002, respectively.

         Intangible assets related to the acquisitions of EXFO Burleigh and EXFO
Photonic Solutions were reviewed for impairment in May 2002 and this resulted in
a pre-tax impairment charge of $23.7 million in the third quarter of 2002.
Considering this write-down, the amortization of intangible assets decreased by
approximately $1.6 million in each of the three quarters of 2003, compared to
the same periods last year. Also, as at August 31, 2002, acquired in-process
research and development and work force related to the acquisitions made over
the last two fiscal years were fully amortized, reducing current year
amortization expense.


                                                                              10



WRITE-DOWN OF GOODWILL AND INTANGIBLE ASSETS

         In May 2002, we performed an impairment test for goodwill and
intangible assets, which resulted in impairment charges of $222.2 million for
goodwill and $23.7 million for intangible assets.

         In May 2003, we performed our annual impairment test for goodwill for
all our reporting units, except for our newly acquired EXFO Gnubi. Also,
considering the persisting unfavorable market conditions affecting our
subsidiaries' industry, we reviewed the carrying value of intangible assets
related to these reporting units.

         As a result of this assessment, we concluded that the carrying value of
goodwill related to EXFO Burleigh and the carrying value of intangible assets
related to EXFO Burleigh and EXFO Photonic Solutions were impaired and we
recorded a charge of $4.5 million to write down goodwill and a pre-tax charge of
$2.9 million to write down core technology. Of the total impairment charge, $6.9
million related to EXFO Burleigh for goodwill and core technology and $555,000
related to EXFO Photonic Solutions for core technology.

         The write-down of goodwill and intangible assets of EXFO Burleigh was
required considering that we will exit the optical manufacturing automation
business since revenue potential represented a long-term prospect. The
write-down of intangible assets of EXFO Photonic Solutions was required because
revenue potential related to its acquired core technology were less than
expected in the short and medium-term.

         However, no impairment of goodwill and intangible assets was required
for EXFO Protocol since revenue potential from the protocol-layer testing market
remains strong in the short and medium-term.

         For the purposes of estimating fair values, we used discounted future
cash flows and multiple of sales. The discounted cash flows were estimated using
periods ranging between 8 and 10 years, discount rate ranging between 15% and
20% and annual growth rate ranging between 5 and 35%. The multiple of sales used
ranged between 0.7 and 2.3. The assumptions used reflect our best estimates.

         Goodwill will be reviewed for impairment in May 2004, or prior to that
date if events or circumstances occur that more likely than not reduce the fair
value of a reporting unit below its carrying value.


RESTRUCTURING AND OTHER CHARGES

         During the first three quarters of 2002, we implemented structured
plans to align our cost structure to market conditions. Under these plans, we
lowered our operating expenses, froze employee salaries, reduced our global work
force and wrote down property, plant and equipment.

         As a result, we recorded restructuring and other charges of $2.9
million, consisting of $410,000 in severance expenses for the 101 employees who
were terminated in the first quarter of 2002; $447,000 in severance expenses for
the 57 employees who were terminated in the second quarter of 2002; $1.2 million
in severance expenses for the 192 employees who were


                                                                              11



terminated as well as $868,000 for the write-down of property, plant and
equipment in the third quarter of 2002.

         In the third quarter of 2003, we implemented an additional
restructuring plan to realign our cost structure to current market conditions.
The first part of this plan, which was effective in May 2003, resulted in 13
employees being terminated and severance expenses of $348,000. The second part
of this plan, which will occur mainly in the fourth quarter of 2003, will reduce
our workforce by 30% overall and related restructuring charges will be recorded
as incurred.

         Our cost-cutting measures represented our best efforts to respond to
the difficult market conditions. However, these efforts may be inappropriate or
insufficient. Our actions in this regard may not be successful in achieving the
cost reductions or other benefits expected, may be insufficient to align our
cost structure to market conditions, or may be more costly or extensive than
anticipated.


INTEREST INCOME, NET

         Net interest income amounted to $379,000 and $261,000 for the three
months ended May 31, 2003 and 2002, respectively. The increase in our net
interest income in the third quarter of 2003, compared to the same period last
year is directly related to the increase in our short-term investments as well
as increase in interest rates.

         Net interest income amounted to $929,000 and $1.2 million for the nine
months ended May 31, 2003 and 2002, respectively. The decrease in our net
interest income for the first three quarters of 2003, compared to the same
period last year, is directly related to the use of short-term investments to
finance the strategic acquisitions of EXFO Protocol and EXFO Gnubi, our
operating activities of fiscal 2002 and the purchases of property, plant and
equipment.

         We expect our net interest income to remain relatively flat over the
next quarter.


FOREIGN EXCHANGE LOSS

         Foreign exchange loss amounted to $600,000 for the three months ended
May 31, 2003, compared to $801,000 for the same period last year. Foreign
exchange loss amounted to $1.3 million for the nine months ended May 31, 2003,
compared to $714,000 for the same period last year.

         The foreign exchange losses are the result of the translation of
operating activities denominated in currencies other than the Canadian dollar.
During the last two quarters of 2003, the Canadian dollar value increased
significantly, as compared to the US dollar resulting in significant foreign
exchange losses during the second and third quarters of 2003. However, we were
able to mitigate these losses with forward exchange contracts.

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


                                                                              12



INCOME TAXES

         Our effective income tax recovery rate was 34.0% (before the future
income tax assets valuation allowance) and 33.6% for the three months ended May
31, 2003 and 2002, respectively and 34.3% (before the future income tax assets
valuation allowance) and 34.6% for the nine months ended May 31, 2003 and 2002,
respectively.

         In the third quarter of 2003, we reviewed the carrying value of our
future income tax assets. Considering current market conditions, as well as the
fact that we recorded losses for the current and past year, and that we are
exiting the automation business, we concluded that it was more likely than not
that some of our future income tax assets will not be recoverable and that a
valuation allowance was required. Even though the carrying period of our future
income tax assets are very long or indefinite, GAAP requires future income tax
assets to be recovered in short periods, especially for companies evolving in
industries such as ours. Accordingly, we recorded a valuation allowance of $24.3
million to write off most of our future income tax assets mainly related to the
parent company, EXFO Protocol and EXFO Burleigh. Future income tax assets
written off consisted mainly in deferred tax losses, research and development
expenses, as well as share issue expenses and provisions and accruals.

         From the $24.3 million valuation allowance, $12.1 million represent tax
assets that can be carried forward indefinitely against future years' taxable
income, while $12.2 million represent tax assets that can be carried forward
against future years' taxable income mainly over the next seven years.

         The valuation allowance will be reversed accordingly as profits are
generated, but the full amount will not be reversed until we demonstrate the
ability to sustain long-term profitability.


AMORTIZATION OF GOODWILL

         In conjunction with the four strategic acquisitions that we made over
the last two fiscal years and in the first quarter of 2003, we recorded $312.0
million in goodwill. The goodwill related to the acquisitions of EXFO Burleigh
and EXFO Photonic Solutions was amortized over five years until August 31, 2002.
This resulted in amortization expenses of $12.5 million and $37.3 million for
the three and the nine months ended May 31, 2002, respectively. The acquisitions
of EXFO Protocol and EXFO Gnubi have been accounted for using new accounting
standards contained in sections 1581 and 3062 of the CICA handbook and,
consequently, goodwill resulting from these acquisitions was not amortized.

         Since September 1, 2002, goodwill related to the acquisitions of EXFO
Burleigh and EXFO Photonic Solutions is no longer amortized under new accounting
standards. Consequently, we no longer have amortization expense for goodwill.


NET LOSS

         Net loss amounted to $38.4 million and $263.8 million for the three
months ended May 31, 2003 and 2002, respectively. In terms of per share amounts,
we recorded a net loss of $0.61 and $4.29 for the three months ended May 31,
2003 and 2002, respectively.


                                                                              13



         Net loss amounted to $44.8 million and $305.6 million for the nine
months ended May 31, 2003 and 2002, respectively. In terms of per share amounts,
we recorded a net loss of $0.71 and $5.06 for the nine months ended May 31, 2003
and 2002, respectively.


PRO FORMA NET LOSS

         As a measure to assess financial performance, we use pro forma net loss
and pro forma net loss per share. Pro forma net loss represents net loss
excluding amortization and write-down of goodwill, future income tax assets
valuation allowance and the after-tax effect of amortization and write-down of
intangible assets, restructuring and other charges as well as inventory and tax
credit write-offs.

         Pro forma net loss amounted to $4.1 million and $3.9 million for the
three months ended May 31, 2003 and 2002, respectively. In terms of pro forma
per share amounts, we recorded a net loss of $0.06 for the three months ended
May 31, 2003 and 2002. Pro forma net loss amounted to $8.8 million and $10.0
million for the nine months ended May 31, 2003 and 2002, respectively. In terms
of pro forma per share amounts, we recorded a net loss of $0.14 and $0.17 for
the nine months ended May 31, 2003 and 2002, respectively.

         Pro forma net loss is reconciled as follows:

         We provide pro forma financial information to help the investor better

LIQUIDITY AND CAPITAL RESOURCES

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

CASH POSITION AND SHORT-TERM INVESTMENTS

         As at May 31, 2003, cash and cash equivalents as well as short-term
investments consisted of $61.8 million. Our working capital was at $83.5
million. Our cash and cash equivalents and short-term investments increased by
$4.0 million since February 28, 2003; this was mainly due to an unrealized
foreign exchange gain on cash and cash equivalents and short-term investments.
This unrealized foreign exchange gain results from the translation of our
financial statements in US dollars, which is our reporting currency and is
recorded in the cumulative translation adjustment in the balance sheet.

         As at May 31, 2003, total commitments under operating leases and
long-term debt over the next twelve months amounted to approximately $1.5
million. Also, in accordance with the assets purchase agreement for the
acquisition of EXFO Gnubi, we may have to pay a contingent cash consideration up
to $2.9 million in December 2003. Finally, we expect to pay $3.0 million in
severances expenses in the upcoming months under our restructuring plan
announced last June. On the other hand, we should recover $2.8 million in income
taxes and tax credits over the next twelve months.


OPERATING ACTIVITIES

         Cash flows used by operating activities were $92,000 and $2.6 million
for the three months ended May 31, 2003 and 2002, respectively. Cash flows used
by operating activities in the third quarter of 2003 were primarily due to the
net loss after items not affecting cash and cash equivalents of $7.2 million,
offset by the decrease of income taxes and tax credits recoverable of $5.1
million, the decrease of inventories of $1.5 million and the increase of
deferred grants of $1.2 million. The decrease in our income taxes and tax
credits recoverable is related to the recovery, during the quarter, of income
taxes and research and development tax credits recoverable from previous
periods. The decrease in our inventories is due to our efforts to maintain them
at the lowest acceptable level considering the continued slowdown in our
industry. Finally, the increase in our deferred grants is due to the cashing in,
during the quarter, of government grants, for which we have not yet met all
conditions to recognize revenue in the statement of earnings.

         During the third quarter of 2003, the major items not affecting cash
and cash equivalents consisted of inventory and tax credit write-offs of $3.9
million, amortization expenses of $2.9 million, future income tax recovery of
$7.2 million, future income tax assets valuation allowance of $24.3 million and
write-down of goodwill and intangible assets of $7.4 million.

         Cash flows provided by operating activities were $9.3 million for the
nine months ended May 31, 2003, compared to cash flows used of $9.0 million for
the same period last year. Cash flows provided by operating activities for the
nine months ended May 31, 2003, were primarily due to the decrease of accounts
receivable of $2.8 million, the decrease of income taxes and tax credits
recoverable of $15.7 million, the decrease of inventories of $5.5 million as
well as the


                                                                              15



increase of deferred grants of $1.1 million, less the net loss after items not
affecting cash and cash equivalents of $15.0 million. The decrease in our
accounts receivable is related to the decrease in our sales level and the
recovery, during the period, of government grants. The decrease in our income
taxes and tax credits recoverable is related to the recovery, during the period,
of income taxes and research and development tax credits recoverable from
previous periods. The decrease in our inventories is due to our efforts to
maintain them at the lowest acceptable level considering the continued slowdown
in our industry. Finally, the increase in our deferred grants is due to the
cashing in, during the quarter, of government grants, for which we have not yet
met all conditions to recognize revenue in the statement of earnings.

         During the nine months ended May 31, 2003, the major items not
affecting cash and cash equivalents consisted of inventory and tax credit
write-offs of $3.9 million, amortization expenses of $8.3 million, future income
tax recovery of $14.3 million, future income tax assets valuation allowance of
$24.3 million and write-down of goodwill and intangible assets of $7.4 million.

FINANCING ACTIVITIES

         Cash flows used by financing activities were $13,000 and $23,000 for
the three months ended May 31, 2003 and 2002, respectively and $76,000 and
$70,000 for the nine months ended May 31, 2003 and 2002, respectively. Cash
flows used by financing activities in these periods were mainly due to the
repayment of our long-term debt.

         As at May 31, 2003, we had credit facilities that provide for advances
of up to CA$10 million (US$7.3 million) under a line of credit. This line of
credit bears interest at prime rate.

         The annual minimum principal repayments of our long-term debt over the
next five fiscal years range from $100,000 to $166 000 a year.

INVESTING ACTIVITIES

         Cash flows used by investing activities were $1.3 million for the three
months ended May 31, 2003, compared to cash flows provided by investing
activities of $1.4 million for the same period last year.

          In the third quarter of 2003, we acquired $1.1 million in short-term
investments and we paid $234,000 for the purchases of property, plant and
equipment and intangible assets.

         Cash flows used by investing activities were $13.1 million for the nine
months ended May 31, 2003, compared to cash flow provided by investing
activities of $8.5 million for the same period last year.

         For the nine months ended May 31, 2003, we acquired for $9.0 million in
short-term investments and we paid $1.9 million and $2.3 million, respectively,
for the acquisition of EXFO Gnubi and the purchases of property, plant and
equipment and intangible assets.

OUTLOOK

         There can be no assurance as to whether and when we will return to
profitability or that our sales will return to prior levels. However, we believe
that our cash balances and short-term investments, combined with cash flows from
operations and available credit facilities, will be


                                                                              16



sufficient to meet our expected liquidity and capital requirements for at least
the next 12 months. On the other hand, possible additional operating losses
and/or possible investments in or acquisitions of complementary businesses,
products or technologies may require additional financing prior to such time.
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.

         On September 1, 2002, we adopted prospectively the new section 3870 of
the CICA handbook, "Stock-Based Compensation and Other Stock-Based Payments" and
the new rules of this section apply to awards granted after that date. As
permitted by the CICA, we choose not to account for the stock-based compensation
costs arising from awards to employees, but we complied with the required pro
forma disclosures with respect to net earnings and net earnings per share in our
interim consolidated financial statements. During the nine months ended May 31,
2003, we granted 1,206,275 options to our employees with an average exercise
price of $2.21. Using the Black-Scholes valuation model, the weighted average
fair value per option is $0.83 and the aggregate stock-based compensation costs
for these options is $1,002,400. These compensation costs will be amortized
using the graded vesting method over the vesting period being four years,
resulting in stock-based compensation costs of $403,500, $307,300, $190,700,
$91,900 and $9,000 over the next five fiscal years, respectively.

         Like many other companies, we do not believe that the use of the
Black-Scholes option valuation model provides a reliable single measure of the
fair value of our employees' stock options and stock awards, mainly because this
model was developed for use in estimating fair value of traded options and
because it requires the input of highly subjective assumptions, including the
expected stock price volatility.


                                                                              17



NEW ACCOUNTING STANDARDS

         In November 2001, the CICA issued section 3870, "Stock-Based
Compensation and Other Stock-Based Payments", which is effective for fiscal
years beginning on or after January 1, 2002. The new section applies to awards
granted on or after the date of adoption, and requires that stock-based payments
to non-employees and direct awards of stock to employees be accounted for using
a fair value-based method. The new section also encourages, but does not
require, the use of a fair value-based method to account for stock-based
compensation costs arising from awards to employees. The new section requires
pro forma disclosures with respect to net earnings and net earnings per share if
a fair value-based method of accounting is not adopted for awards granted to
employees. We adopted this new standard prospectively on September 1, 2002. We
elected not to account for stock-based compensation costs arising from awards to
our employees using the fair value-based method and, consequently, the adoption
of this new standard had no impact on our financial results. However, we
complied with the standard by providing the required pro forma disclosures.

         In August 2001, the CICA issued section 3062 "Goodwill and Other
Intangible Assets", which is effective for fiscal years beginning on or after
January 1, 2002. Section 3062 changes the accounting for goodwill from an
amortization method to an impairment-only approach. Thus, amortization of
goodwill, including goodwill recorded in past business combinations, ceased upon
the adoption of this section. For any acquisitions completed after June 30,
2001, goodwill is not amortized.

         We adopted section 3062 prospectively on September 1, 2002. Since the
adoption of this new section, goodwill recorded prior to July 1, 2001, is no
longer subject to amortization. Also, under the transitional provisions of the
section, we performed an initial impairment test to identify goodwill impairment
using a fair value-based method. Under the new section, goodwill impairment
exists when the carrying value of a reporting unit exceeds its fair value. For
the purposes of the impairment test, we allocated our existing goodwill to our
reporting units and completed an evaluation of the fair value of such reporting
units. Based on the comparison of the fair value of the reporting units to their
carrying value, goodwill of the reporting units was not considered impaired at
that moment.

         Furthermore, goodwill must be tested for impairment on an annual basis
or more frequently if events or circumstances occur that more likely than not
reduce the fair value of a reporting unit below its carrying value. Any
impairment loss arising from this test will be charged to earnings in the period
in which it is incurred. We elected to perform our annual impairment test in May
of each year for all our reporting units. Please refer to the section entitled
"Write-down of intangible assets and goodwill" of this document for a complete
description of this test.

         In November 2002, the CICA issued section 3063, "Impairment of
Long-Lived Assets", which is effective for fiscal years beginning on or after
April 1, 2003. This new section changes existing rules for recognition and
measurement of long-lived assets held for use. The section requires that an
impairment charge be measured as the excess of the carrying value of an
intangible asset over its fair value. We adopted this new section prospectively
on April 1, 2003, and test our intangible assets under its new provisions.
Please refer to the section entitled "Write-down of intangible assets and
goodwill" of this document for a complete description of this test.

         In November 2002, the CICA issued section 3475, "Disposal of Long-lived
Assets and Discontinued Operations", which is effective for disposal activities
initiated by an enterprise's commitment to a plan on or after May 1, 2003. Under
the new section, a long-lived asset to be


                                                                              18



disposed of other than by sale continues to be classified as held and used until
it is disposed of; a long-lived asset classified as held for sale is measured at
the lower of its carrying value of fair value less cost to sell; a loss
recognized on classification of long-lived assets as held for sale or a group of
assets as a discontinued operation does not include future operating losses,
other than to the extent they are included in the fair value of the asset; and
discontinued operations are defined more broadly than under existing rules. We
adopted this new standard prospectively on May 1, 2003, and its adoption had no
impact on our financial statements.

RISKS AND UNCERTAINTIES

         Over the past few years, we have been able to manage our activities,
focus on research and development of new and innovative products, penetrate
international markets and close important 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 fiber-optic test,
measurement and monitoring industry involve the rapid development of new
products that have short life cycles and require extensive research and
development; the difficulty of retaining highly skilled employees as well as
offering them effective training programs; 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 the important strategic acquisitions we have made
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 the 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 and cash equivalents, 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 cash equivalents 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.
