        o   LEADERSHIP POSITION IN FIBER-TO-THE-PREMISES TEST MARKET

QUEBEC CITY,  CANADA,  March 29, 2005--EXFO  Electro-Optical  Engineering Inc.
(NASDAQ:  EXFO; TSX: EXF.SV)  announced today that it achieved GAAP break-even
in the second quarter of fiscal 2005.

Sales  increased 37.1% to US$23.1 million in the second quarter ended February
28,  2005,  from US$16.9  million in the second  quarter of 2004 and 7.1% from
US$21.6  million in the first quarter of 2005. Net bookings  improved 39.8% to
US$24.9  million in the second quarter of fiscal 2005 from US$17.7  million in
the same period last year and 6.5% from US$23.3  million in the first  quarter
of 2005.

Gross margin accounted for 54.9% of sales in the second quarter of fiscal 2005
compared to 55.4% in the second quarter of 2004 and 52.7% in the first quarter
of 2005.

GAAP net earnings in the second  quarter of fiscal 2005 totaled US$9 thousand,
or US$0.00 per share,  compared to a net loss of US$2.9  million,  or US$ 0.04
per share, in the same period last year and a net loss of US$2.4  million,  or
US$0.03 per share, in the first quarter of 2005.

On a pro forma  basis*,  net  earnings  in the second  quarter of fiscal  2005
amounted  to US$1.5  million or US$0.02  per share,  compared to a net loss of
US$1.5 million,  or US$0.02 per share, in the second quarter of 2004 and a net
loss of US$0.8 million, or US$0.01 per share, in the first quarter of 2005.

"I am delighted that we achieved GAAP break-even, posted our sixth consecutive
quarterly  increase in sales and bookings,  while being  recognized by Frost &
Sullivan for capturing the largest  market-share gains in the optical test and
measurement industry in calendar 2004," said Germain Lamonde, EXFO's Chairman,
President and CEO.  "These  milestones,  combined with 36% sales growth in the
first half of fiscal 2005  compared  to the same  period last year,  represent
clear-cut  evidence  that EXFO gained  sizeable  market-share,  established  a
leadership  position in  fiber-to-the-premises  testing,  and strengthened its
unique value proposition for  next-generation  IP networking through sustained
R&D spending during the telecom downturn."

SECOND-QUARTER BUSINESS HIGHLIGHTS

        o   Growing through  market-share  gains, EXFO received for the second
            consecutive year the Growth Strategy Leadership Award from Frost &
            Sullivan  following  the  quarter-end.   The  award  is  presented
            annually to the company whose visionary growth strategy  generates
            the  largest  market-share  gains in the global  fiber-optic  test
            equipment  (FOTE)  market.  Based on a report by Frost & Sullivan,
            EXFO increased its market share from 8.4% to 10.4% overall in 2004
            to attain the second overall position  worldwide,  while expanding
            its leadership position from 17.4% to 22.2% of the network service
            provider market.

        o   Continuing  its  leadership  in the  FTTx  (fiber-to-the-premises,
            fiber-to-the-node,  fiber-to-the  curb) test market,  EXFO shipped
            several such orders to a US-based,  Tier-1  telecom  carrier,  who
            accounted  for 21.4% of sales in the second  quarter of 2005,  and
            the company received long-term,  sole-source  approval for a suite
            of FTTx test  solutions from a second Tier-1 carrier in the United
            States.

        o   Focusing on  profitability,  EXFO reached GAAP  break-even  in the
            second  quarter of 2005 and was  profitable  on a pro forma basis*
            for the third time in the last four quarters.

        o   Taking advantage of its strong R&D program, EXFO launched five new
            products  in the  second  quarter,  including  amongst  others  an
            All-Band  Component   Analyzer  for  FTTx  and   coarse-wavelength
            division multiplexing (CWDM) manufacturing/R&D applications. Sales
            of new  products  that have been on the  market  two years or less
            accounted for 45.5% of sales in the second quarter of 2005.

BUSINESS OUTLOOK

EXFO forecasts  sales between US$23.0 million and US$26.0 million and GAAP net
earnings  (loss)  between a net loss of US$0.02 per share and net  earnings of
US$0.01 per share for the third quarter of fiscal 2005. Excluding  stock-based
compensation costs,  amortization of intangible assets,  restructuring charges
and other unusual items,  the company expects to report pro forma net earnings
between US$0.00 per share and US$0.03 per share.

1    INTERIM FINANCIAL INFORMATION

     The financial information as at February 28, 2005, and for the three- and
     six-month  periods  ended  February 29, 2004 and  February  28, 2005,  is
     unaudited. In opinion of management, all adjustments necessary to present
     fairly the results of these periods in accordance with generally accepted
     accounting principles in Canada have been included.  The adjustments made
     were  of  a  normal  and  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.  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 AND PRONOUNCEMENTS

     On  September  1, 2004,  the company  prospectively  adopted the Canadian
     Institute of Chartered  Accountants  (CICA)  handbook  sections  1100 and
     1400,  "Generally Accepted Accounting  Principles" and "General Standards
     of  Financial  Statement  Presentation".  Among other  things,  these new
     sections  define  generally   accepted   accounting   principles  (GAAP),
     establish  the  relative  authority of various  types of CICA  Accounting
     Standards  Board   pronouncements  and  clarify  the  role  of  "industry
     practice" in applying  GAAP.  The adoption of these new  standards had no
     significant impact on the financial statements of the company.

     Furthermore,  in  January  2005,  the CICA  issued  four  new  accounting
     standards  in  relation  with   financial   instruments:   section  3855,
     "Financial  Instruments -  Recognition  and  measurement",  section 3865,
     "Hedges",   section  1530,   "Comprehensive  Income"  and  section  3251,
     "Equity".

     Section 3855 expands on section 3860, "Financial Instruments - Disclosure
     and  Presentation",  by prescribing when a financial  instrument is to be
     recognized on the balance sheet and at what amount. It also specifies how
     financial  instrument  gains  and  losses  are  to be  presented  in  the
     financial statements.

     Section 3865 provides alternative treatments to section 3855 for entities
     which  choose  to  designate   qualifying   transactions  as  hedges  for
     accounting purposes.  It replaces and expands on Accounting Guideline 13,
     "Hedging  Relationships",  and the  hedging  guidance  in  Section  1650,
     "Foreign  Currency  Translation"  by specifying  how hedge  accounting is
     applied and what disclosure are necessary when it is applied.

     Section 1530,  "Comprehensive  Income"  introduces a new  requirement  to
     temporarily present certain gains and losses outside net income.

     Consequently,  Section 3250, "Surplus", has been revised as Section 3251,
     "Equity".

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


     Sections 1530,  3251, 3855 and 3865 apply to fiscal years beginning on or
     after  October 1, 2006.  The company  will adopt these new  standards  on
     September 1, 2007 and has not yet determined the impact they will have on
     its financial statements.


3    RESTRUCTURING CHARGES

     During the three- and  six-month  periods  ended  February 28, 2005,  the
     company   incurred   $244,000   and   $444,000   respectively,   for  the
     consolidation  of the Photonics and Life Sciences  Division.  The company
     expects to incur an additional  $160,000,  mainly in the third quarter of
     fiscal 2005, for a total of  approximately  $2,600,000 in charges related
     to this consolidation process. In addition, during the three months ended
     February 28, 2005,  the company  recorded  adjustments of $190,000 to the
     fiscal 2003 plan because actual charges were lower than expected.

     Changes in the restructuring charges payable are as follows:

7    INCOME TAXES

     During the three- and  six-month  periods  ended  February 28, 2005,  the
     company  recorded income taxes of $697,000 and $1,422,000,  respectively,
     representing income tax payable in some specific tax jurisdictions.

     Since  fiscal  2003,  the  company has been  recording  a full  valuation
     allowance  against its future income tax assets because it is more likely
     than not that these assets will not be recovered.  This caused its income
     tax rate to be distorted in relation to its pre-tax accounting income.


8    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

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


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

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

     In  June  2003,  a  committee  of  the   company's   Board  of  Directors
     conditionally   approved  a  proposed   settlement   between  the  issuer
     defendants,  the individual defendants,  and the plaintiffs. If approved,
     the  settlement  would  provide,  among  other  things,  a release of the
     company and of the individual  defendants for the conduct  alleged in the
     action to be wrongful in the amended  complaint.  The company would agree
     to  undertake  other  responsibilities  under the  settlement,  including
     agreeing to assign away, not assert,  or release certain potential claims
     the  company  may have  against its  underwriters.  Any direct  financial
     impact  of  the  proposed  settlement  is  expected  to be  borne  by the
     company's insurance carriers.

     On June 25, 2004, the Plaintiffs  moved for  Preliminary  Approval of the
     settlement,  and the Underwriter defendants have opposed that motion. The
     court  granted the  preliminary  approval  motion on February  15,  2005,
     subject to certain modifications. The parties are directed to report back
     to the court  regarding  the  modifications.  If the  parties are able to
     agree  upon  the  required  modifications,  and  such  modifications  are
     acceptable to the court, notice will be given to all class members of the
     settlement, a "fairness" hearing will be held and if the court determines
     that the settlement is fair to the class members,  the settlement will be
     approved.  There can be no assurance that this proposed  settlement would
     be approved and implemented in its current form, or at all. Therefore, it
     is not possible to predict the final  outcome of the case,  nor determine
     the amount of any possible losses.  If the settlement  process fails, the
     company will continue to defend its position in this  litigation that the
     claims against it, and its officers, are without merit.  Accordingly,  no
     provision  for  this  case  has  been  made in the  interim  consolidated
     financial statements as at February 28, 2005.

9    STOCK-BASED COMPENSATION PLANS

     During the three months ended February 28, 2005, the company  amended its
     stock option plan to include the award of Restricted  Stock Units (RSUs).
     Each RSU  entitles  employees  to receive one  subordinate  voting  share
     without  consideration  on the vesting dates  established by the Board of
     Directors of the company,  subject to a minimum term of three years and a
     maximum  term of ten years from the award date.  RSUs  granted  under the
     plan expire at the latest ten years from the date of grant.

     Furthermore, during the same period, the company established a Deferred
     Stock Unit (DSUs) plan for the members of the Board of Directors as part
     of their annual retainer fees. Each DSU entitles the Board members to
     receive one subordinate voting share. DSUs are acquired on the date of
     grant and will be redeemed in subordinate voting shares when the Board
     member will cease to be Director of the company.

     During the three months ended  February  28,  2005,  the company  granted
     176,185 RSUs and 5,350 DSUs.  These awards have been accounted for in the
     financial statements using the fair value-based method.

     The diluted loss per share for the periods ended  February 29, 2004,  and
     the six months ended  February  28, 2005,  was the same as the basic loss
     per share since the dilutive  effect of stock options,  restricted  stock
     awards  and   deferred   stock  units  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.

     RESEARCH AND DEVELOPMENT TAX CREDITS

     During the three- and  six-month  periods  ended  February  29,  2004 and
     February 28, 2005, net research and  development  expenses under Canadian
     GAAP included tax credits that are refundable  against  taxable income of
     $842,000 and  $1,193,000,  respectively.  Under U.S. GAAP,  these credits
     would have been  recorded in the income  taxes.  This  difference  had no
     impact on the net loss and net loss per share  figures for the  reporting
     periods under U.S. GAAP.


     STATEMENTS OF CASH FLOWS

     For the three and six-month  periods ended February 29, 2004 and February
     28, 2005, there were no significant differences between the statements of
     cash flows under Canadian GAAP as compared to U.S. GAAP.


     NEW ACCOUNTING STANDARDS

     In November 2004,  the Financial  Accounting  Standards  Board (FASB) has
     issued Statement of Financial Position (SFAS) 151,  "Inventory Costs", an
     amendment of ARB No. 43, Chapter 4. The amendments  made by SFAS 151 will
     improve  financial  reporting by clarifying  that any abnormal  amount of
     idle facility  expenses,  freight,  handling costs,  and wasted materials
     (spoilage)  should  be  recognized  as  current-period   charges  and  by
     requiring the allocation of fixed production overheads to inventory based
     on the  normal  capacity  of the  production  facilities.  This  SFAS  is
     effective  for inventory  costs  incurred  during fiscal years  beginning
     after  June 15,  2005.  The  company  will adopt  this new  statement  on
     September 1, 2005, and does not expect this to have a significant  impact
     on its financial statements.

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

INDUSTRY OVERVIEW

         Access network  deployments  in the United States  remained a primary
growth  driver in the  global  telecommunications  industry  during the second
quarter of fiscal 2005.  Leading US-based telecom carriers (telcos)  continued
massive  deployments of fiber deeper into access  networks in order to provide
consumers with increased bandwidth and services.  These carriers, along with a
number of  Tier-II  and local and rural  Tier-III  players,  have opted for an
assortment of deployment  scenarios  including  fiber-to-the-premises  (FTTP),
fiber-to-the-node  (FTTN),  or  fiber-to-the-curb  (FTTC),  depending on their
respective network architectures.


                                                                             1


         Leading U.S. telcos are accelerating spending on fiber deployments in
access  networks  because  they  are  embroiled  in a market  war  with  cable
companies  (cablecos)  to offer  bundled  voice,  data and video  services  to
consumers in preparation to migration to IP-Networking. Consequently, wireline
capital  expenditures are expected to increase in 2005, despite  consolidation
announcements in the industry.

         While fiber  deployments in access networks are stronger in the North
American  market  (with  the  exception  of Japan  and  Korea),  the  shift to
converged Internet protocol  (IP)-based networks is expected to be a worldwide
phenomenon.  Telecom operators, on a global basis, are increasingly turning to
a single, IP-based network architecture in order to deliver increased services
at drastically reduced costs.

         These key market  trends  affected  multiple  segments  of the global
telecommunications supply chain. System manufacturers benefited from orders by
both telcos and cablecos for next-generation, converged IP networks as well as
through major investments by telcos in access networks.  Component vendors saw
incremental demand for optical components that support IP-based systems.  Some
test and  measurement  equipment  vendors  attracted  the attention of telcos,
cablecos, system manufacturers and component vendors, especially ones offering
test  solutions  for IP optical  networking  and/or  FTTx (FTTP,  FTTN,  FTTC)
applications.


COMPANY OVERVIEW

         Sales reached $23.1 million in the second  quarter of fiscal 2005, of
which 21.4% was shipped to a U.S.-based, Tier-1 telecom carrier. Historically,
sales to our top  customer  represented  less  than  10% of  total  sales on a
quarterly  basis,  but in the last four  quarters,  we had one  customer  that
accounted for more than 10% of our sales. We believe this sales  concentration
is largely due to our leadership position in the FTTx test market.

         We also reported  GAAP net earnings of $9,000 for the second  quarter
of fiscal 2005.  This marked the first time since the second quarter of fiscal
2001 that we were profitable on a GAAP basis.

         In the first  half of  fiscal  2005,  we  launched  12 new  products,
including   an   All-Band    Component    Analyzer   for   FTTx   and   coarse
wavelength-division  multiplexing (CWDM) applications in the manufacturing/R&D
market; a next-generation SONET/SDH analyzer for testing data-centric Internet
Protocol (IP) networks;  a Gigabit  Ethernet test solution with  voice-over-IP
(VoIP) test  capabilities;  a suite of three handheld test instruments for the
installation and maintenance  market;  and an optical spectrum  analyzer (OSA)
for CWDM applications in metro and access networks.

         Following the end of the second quarter,  EXFO was named recipient of
the 2005  Growth  Strategy  Leadership  Award by Frost &  Sullivan,  a leading
market  research  firm in the  telecommunications  test  sector.  The award is
presented  annually to the company whose visionary  growth strategy  generates
the largest market-share gains in the global fiber-optic test equipment market
in the previous year. Based on a report by Frost & Sullivan,  we increased our
market share from 8.4% in fiscal 2003 to 10.4% in 2004. This marked the second
consecutive year that we have earned this industry award.

         In the first half of fiscal 2005, we recorded a foreign exchange loss
of $772,000,  or $0.01 per share, due to the significant increase in the value
of the  Canadian  dollar  compared  to the US dollar  during that  period.  In
addition to this foreign exchange loss, our P&L line items of


                                                                             2


2005 were also negatively affected by this appreciation of the Canadian dollar
as a significant  portion of our expenses are incurred in Canadian dollars and
we report our results in US dollars.

         In the  second  quarter  of fiscal  2005,  we  recorded  $244,000  in
restructuring  expenses  for  the  consolidation  of our  Photonics  and  Life
Sciences  Division.  This amount was  recorded  in  addition  to the  $200,000
incurred in the first quarter of 2005. So far, we have  sustained $2.0 million
in  restructuring  and other  charges  since  the  fourth  quarter  of 2004 in
conjunction  with  this  consolidation  process  and we  expect  to  incur  an
additional $160,000,  mainly in the third quarter of 2005, for a total of $2.6
million in charges  related to this  process.  We estimate that we will derive
$1.5 million in annual savings from these streamlined operations.


OUR STRATEGY, KEY PERFORMANCE INDICATORS AND CAPABILITY TO DELIVER RESULTS

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


CRITICAL ACCOUNTING POLICIES AND ESTIMATES

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

         On September 1, 2004, we prospectively adopted the following new
Canadian Institute of Chartered Accountants (CICA) handbook sections:

         o   Section 1100, "Generally Accepted Accounting Principles" 

         o   Section 1400, "General Standards of Financial Statement
             Presentation"

         Furthermore,  in January  2005,  the CICA issued four new  accounting
standards in relation with  financial  instruments:  section 3855,  "Financial
Instruments - Recognition and measurement",  section 3865,  "Hedges",  section
1530, "Comprehensive Income" and section 3251, "Equity".

         Please  refer  to  note  2  to  our  interim  consolidated  financial
statements for further  information about these new standards and their impact
on our financial statements.


                                                                             3

SALES

         For the three  months  ended  February  28,  2005,  our global  sales
increased  37.1% to $23.1  million from $16.9 million for the same period last
year, with an 84%-16% split in favor of our Telecom Division.

         For  the six  months  ended  February  28,  2005,  our  global  sales
increased  36.2% to $44.7  million from $32.8 million for the same period last
year, with an 82%-18% split in favor of our Telecom Division.

TELECOM DIVISION

         For the three  months ended  February 28, 2005,  sales of our Telecom
Division  increased  45.9% to $19.5  million  from $13.3  million for the same
period last year.

         For the six months  ended  February  28,  2005,  sales of our Telecom
Division  increased  44.8% to $36.9  million  from $25.5  million for the same
period last year.

         Since the  second  half of fiscal  2004,  we have  benefited  from an
increased  demand for our test  solutions  following  the  deployment of fiber
deeper into access networks (FTTP, FTTC and FTTN), in particular from a Tier-1
NSP customer, who accounted for 21% of our telecom sales in the second quarter
of fiscal 2005 and 23% in the first half of 2005.  In  addition,  the positive
spending environment helped us increase our sales for these periods.

PHOTONICS AND LIFE SCIENCES DIVISION

         For the three months ended February 28, 2005,  sales of our Photonics
and Life Sciences  Division  increased  3.6% to $3.7 million from $3.5 million
for the same period last year.

         For the six months ended  February 28, 2005,  sales of our  Photonics
and Life Sciences  Division  increased  6.4% to $7.8 million from $7.4 million
for the same period last year.

         The  increase  in  sales  during  these  periods  is  mainly  due  to
market-share  gain in the  illumination  market  as well  as  increased  sales
activities in the curing market year-over-year.

         Overall,  for the two divisions,  net accepted orders increased 39.8%
to $24.9  million in the second  quarter of fiscal 2005 from $17.7 million for
the same period last year. The  improvement in the  telecommunications  market
environment, the increased demand for our test solutions for FTTx applications
as well as  market-share  gain in the  telecommunications  and  life  sciences
markets helped us increase our bookings  year-over-year.  Based on a report by
Frost & Sullivan,  in 2004,  we increased our market share by 200 basis points
compared  to  2003.  Our net  book-to-bill  ratio  rose to 1.07 in the  second
quarter of 2005,  from 1.05 for the same  period  last year.  In the  previous
quarter, the net book-to-bill ratio reached 1.08.

GEOGRAPHIC DISTRIBUTION

         For the three months ended February 28, 2005,  sales to the Americas,
Europe-Middle  East-Africa  (EMEA) and Asia-Pacific  (APAC) accounted for 65%,
20% and 15% of global sales,  respectively.  For the corresponding period last
year,  sales to the Americas,  EMEA and APAC accounted for 67%, 18% and 15% of
global sales,  respectively.  Our sales to the Americas,  which  increased 33%
year-over-year,  benefited from the recent  deployments of fiber deeper in the
access networks that mainly occurred in the United States as mentioned  above.
Our sales to EMEA increased more significantly  (52%)  year-over-year,  mainly
due to market-share gains in both divisions,  following our efforts to develop
this market. Our sales


                                                                             6


to APAC  increased  39%  year-over-year.  Most of our sales to this market are
made through  tenders that may vary in number and  importance  from quarter to
quarter.

         For the six months ended  February 28, 2005,  sales to the  Americas,
EMEA and APAC  accounted for 68%, 19% and 13% of global  sales,  respectively.
For the corresponding  period last year, sales to the Americas,  EMEA and APAC
accounted for 66%, 17% and 17% of global sales, respectively.

         Through our two  divisions,  we sell our products to a broad range of
customers,  including Network Service Providers,  optical component and system
manufacturers,  as well as high-tech industrial manufacturers and research and
development laboratories.  During the three months ended February 28, 2005, we
had a high amount of sales to a single  customer  that  accounted for 21.4% of
our total sales and our top three customers  accounted for 27.8% of our sales.
For the  corresponding  period last year, no customer  accounted for more than
8.1% of our  sales  and our top  three  customers  accounted  for 16.5% of our
sales.  For the six months ended  February 28, 2005,  we had one customer that
accounted for 23.1% of our total sales and our top three  customers  accounted
for 27.9% of our sales.  For the  corresponding  period last year, no customer
accounted  for  more  than  6.8% of our  sales  and our  top  three  customers
accounted for 17.5% of our sales.

         Considering  the sales level and the net  book-to-bill  ratio for the
first half of fiscal  2005 as well as the  benefits  expected  from our recent
product introductions, we still believe that we will achieve our KPI; that is,
20% sales growth year-over-year in a stable telecommunications market.


GROSS MARGIN

         Gross  margin  amounted to 54.9% of sales for the three  months ended
February  28, 2005,  compared to 55.4% for the same period last year.  Despite
the  significant  increase in sales  year-over-year  (37.1%),  which lead to a
better  absorption  of our fixed  manufacturing  costs and the benefits of our
cost reduction programs,  our gross margin decreased 0.5%. A stronger Canadian
dollar, compared to the US dollar year-over-year, had a negative impact on our
gross  margin as some  cost of sales  elements  are  denominated  in  Canadian
dollars. Also, a different customer mix, product mix, as well as the increased
pricing  pressure  observed  in the  second  quarter  of fiscal  2005  further
contributed to the reduction of the gross margin.

         Gross  margin  amounted  to 53.8% of sales for the six  months  ended
February 28, 2005, compared to 53.3% for the same period last year. The slight
increase in our gross margin can be explained by the following factors. First,
we were able to reduce our cost of goods sold with lower  purchasing  price of
various  commodities  we buy.  In  addition,  the  significant  rise in  sales
year-over-year  (36.2%)  resulted in an increase in  manufacturing  activities
allowing  us to better  absorb  our fixed  manufacturing  costs.  Furthermore,
streamlined  operations following our consolidation actions in fiscal 2004 and
cost-reduction programs allowed us to improve our gross margin year-over-year.
However, a stronger Canadian dollar, compared to the US dollar year-over-year,
prevented  us from  further  improving  our gross margin as some cost of sales
elements  are  denominated  in  Canadian  dollars.  In  addition,  a different
customer  mix and pricing  pressure  observed in the first half of fiscal 2005
also prevented us from further improving our gross margin.


                                                                             7


         Considering the current state of the telecommunications industry, our
cost-reduction  measures,  our tight control on operating costs as well as our
expected sales growth, we believe that our gross margin will improve in fiscal
2005,   compared   to  2004.   However,   our  gross   margin  may   fluctuate
quarter-over-quarter  as our sales may  fluctuate.  Furthermore,  any  further
increase in the stength of the Canadian  dollar in the upcoming  quarters will
have a negative impact on our gross margin.  Finally,  our gross margin can be
negatively  affected  by  increased  competitive  pricing  pressure,  customer
concentration,  increased  obsolescence  costs, shifts in customer and product
mix,  under-absorption  of fixed  manufacturing costs and increases in product
offerings by other suppliers in our industry.


SELLING AND ADMINISTRATIVE

         For  the  three   months  ended   February  28,  2005,   selling  and
administrative expenses were $7.7 million, or 33.4% of sales, compared to $6.8
million, or 40.0% of sales for the same period last year.

         For  the  six  months   ended   February   28,   2005,   selling  and
administrative  expenses were $15.1  million,  or 33.8% of sales,  compared to
$12.6 million, or 38.4% of sales for the same period last year.

         The increase in our selling and administrative expenses in dollars is
mainly  related to the  significant  increase in our sales,  which  caused our
commission expenses to increase  year-over-year,  and to the increase of sales
and  marketing  expenditures  (including  head-counts),   resulting  from  our
strategic  decision to expand the sales  organization  to better  leverage the
various  leading  technologies  developed  over  the  past  fiscal  years.  In
addition,   a   stronger   Canadian   dollar,   compared   to  the  US  dollar
year-over-year,  further increased our selling and administrative expenses, as
more than half of our  selling and  administrative  expenses  are  incurred in
Canadian dollars.  Furthermore,  stock-based compensation costs were higher in
fiscal 2005 than in 2004,  further  increasing our selling and  administrative
expenses year-over-year. However, we were able to mitigate the increase in our
selling  and  administrative  expenses  as well as reduce  these  expenses  in
percentage of sales year-over-year due to tight cost-control  measures and our
recent consolidation actions.

         For the upcoming  quarters,  we expect our selling and administrative
expenses  to  increase  in dollars,  while  remaining  relatively  stable as a
percentage  of sales.  In  particular,  we expect our  commission  expenses to
increase as sales volume increases. Also, considering our goal of becoming the
leading player in the telecom test and  measurement  space,  we will intensify
our sales and marketing efforts,  both domestic and international,  which will
also cause our expenses to rise. Finally, any further increase in the strength
of the Canadian dollar will also cause our selling and administrative expenses
to  increase,  as more than half of these  expenses  are  incurred in Canadian
dollars.


RESEARCH AND DEVELOPMENT

         For the three months ended  February  28,  2005,  gross  research and
development expenses totaled $3.8 million, or 16.5% of sales, compared to $4.3
million,  or 25.4% of sales for the same period last year.


                                                                             8


         For the six months  ended  February  28,  2005,  gross  research  and
development expenses totaled $7.6 million, or 17.0% of sales, compared to $7.9
million, or 23.9% of sales for the same period last year.

         The  decrease  in our gross  research  and  development  expenses  in
dollars is mainly  attributable to the consolidation of our Photonics and Life
Sciences  Division  activities,  as we refocused  our R&D  activities  in this
division  based on our  strategy to leverage  existing  telecom  technologies.
Also,  mix and  timing of R&D  projects  can  explain  the  decrease  in gross
research and development expenses for both periods.

         On the other hand,  in fiscal  2005,  most of our gross  research and
development expenses were incurred in Canadian dollars as we have consolidated
most of our R&D activities in Canada.  Consequently,  the significant increase
in  the   strength  of  the  Canadian   dollar   compared  to  the  US  dollar
year-over-year caused our gross research and development expenses to increase.

         The  decrease  in  gross  research  and  development  expenses  as  a
percentage of sales is directly  related to the decrease in our gross research
and development expenses, combined with the significant increases in our sales
year-over-year.

         For the three months ended  February 28, 2005, tax credits and grants
from  the  Canadian  federal  and  provincial  governments  for  research  and
development  activities  were $1.0  million,  or 27.2% of gross  research  and
development  expenses,  compared to $794,000,  or 18.5% of gross  research and
development  expenses for the same period last year.  For the six months ended
February 28, 2005, these tax credits and grants were $2.1 million, or 27.0% of
gross research and development expenses, compared to $1.5 million, or 19.6% of
gross research and development expenses for the same period last year.

         The  increase in our tax credits and grants is mainly  related to the
increase in our eligible  gross research and  development  expenses in Canada,
since  we  were   entitled  to  similar   grant   programs   and  tax  credits
year-over-year.  Following the  consolidation of our R&D activities in Canada,
we incurred  most of our R&D expenses in Canada,  where we are entitled to R&D
tax credits and grants.

         We  still  invested   significantly   in  research  and   development
activities in the first half of fiscal 2005,  mainly in our Telecom  Division,
as we firmly believe that innovation and new product  introductions are key in
gaining  market  share in the current  economic  environment  and ensuring the
long-term growth and profitability of the company.

         For the first half of fiscal 2005, 44% of our sales  originated  from
products  that have been on the market for two years or less.  The 2005 figure
thus far has almost reached our fiscal 2005 objective of 45%. With the help of
the 20 new  products  brought to the market  place in fiscal 2004 - several of
which were  released  in the second  half of the fiscal  year - and the 12 new
ones lauched in the first half of fiscal  2005,  we remain  confident  that we
will achieve our KPI of 45% for fiscal 2005.

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


                                                                             9


AMORTIZATION OF PROPERTY, PLANT AND EQUIPMENT

         For the  three  months  ended  February  28,  2005,  amortization  of
property,  plant and equipment was $1.1 million,  compared to $1.3 million for
the same  period  last  year.  For the six months  ended  February  28,  2005,
amortization  expenses amounted to $2.2 million,  compared to $2.6 million for
the same period last year.  The  decrease in  amortization  expenses in fiscal
2005,  compared to 2004,  despite the significant  increase in the strength of
the Canadian dollar compared to the US dollar,  is mainly due to the fact that
some of our property, plant and equipment became fully amortized during fiscal
2004.


RESTRUCTURING CHARGES

         For  the  three  and  the  six  months   ended   February  28,  2005,
restructuring charges amounted to $54,000 and $254,000,  respectively.  During
these periods, we recorded $244,000 and $444,000, respectively, in conjunction
with the  consolidation  of our  Photonics and Life  Sciences  Division.  This
consolidation process, which is substantially  completed,  started in the last
quarter of fiscal 2004 and will extend  through the third and fourth  quarters
of 2005.  Also, in the second quarter of fiscal 2005, we recorded  adjustments
of $190,000 to reverse accrued expenses related to our 2003 restructuring plan
because  actual  expenses were lower than expected.  During the  corresponding
periods of 2004, we had no restructuring charges.


INTEREST AND OTHER INCOME

         For the three months ended  February  28, 2005,  interests  and other
income  amounted  to $625,000  compared  to $514,000  for the same period last
year. During the second quarter of fiscal 2005, our interest income was higher
than the  corresponding  period of 2004, mainly because of the increase in our
cash position  following our public offering in February 2004 and the increase
in interest rates. However, other income in the second quarter of fiscal 2004,
included revenues from the non-recurring sale of certain excess assets.

         For the six months  ended  February  28,  2005,  interests  and other
income amounted to $1.3 million  compared to $670,000 for the same period last
year.  The increase in interest  income  year-over-year  is due in part to the
increase in our cash position  following our public  offering in February 2004
and the  increase in  interest  rates.  Also,  during the first half of fiscal
2005,  we  recovered  R&D tax  credits  earned in  previous  years and we were
granted $249,000 in interests by the tax authorities.


FOREIGN EXCHANGE GAIN (LOSS)

         For the three months ended  February 28, 2005,  the foreign  exchange
gain amounted to $263,000 compared to $427,000 for the same period last year.

         Foreign  exchange gains and losses are the result of the  translation
of operating  activities  denominated  in  currencies  other than the Canadian
dollar.  During the three months ended February 28, 2005, the Canadian  dollar
value  decreased  compared to the US dollar,  resulting in a foreign  exchange
gain during the quarter. During the same period last year, the Canadian dollar
value decreased more significantly than in fiscal 2005,  resulting in a higher
foreign exchange gain during that period.


                                                                            10


         For the six months ended February 28, 2005, the foreign exchange loss
amounted  to $772,000  compared to $43,000 for the same period last year.  The
significant  exchange  loss  recorded  in the first half of fiscal 2005 is the
result of the  significant  and rapid  increase  in the value of the  Canadian
dollar  compared to the US dollar in the first half of fiscal 2005,  resulting
in a significant  foreign  exchange  loss during that period.  During the same
period last year,  the  Canadian  dollar  value also  increased  significantly
compared to the US dollar,  resulting in a less important exchange loss during
that  quarter.  Higher  levels of activity  in the first half of fiscal  2005,
compared to the same pariod last year,  further  increased  the exchange  loss
year-over-year.

         We  manage  our  exposure  to  currency  risk with  forward  exchange
contracts.  In addition,  some of our operating  activities are denominated in
currencies  other than the Canadian  dollar,  which further  hedges this risk.
However, any further increase in the value of the Canadian dollar, compared to
the US dollar, will have a negative impact on our operating results.


INCOME TAXES

         For the three months ended  February 28, 2005,  we recorded an income
tax  expense of $697,000  compared to $341,000  for the same period last year.
For the six months ended  February 28, 2005, we recorded an income tax expense
of $1.4  million  compared to an income tax  recovery of $1.1  million for the
same period last year.

         The  income tax  expense  recorded  in fiscal  2005 and in the second
quarter of fiscal 2004  represented  income taxes payable in some specific tax
jurisdictions.

         The income tax recovery recorded in the first half of fiscal 2004 was
mainly due to the  recovery,  in the first quarter of 2004, of $1.4 million of
income  taxes  paid  in  previous  periods  following  the  receipt  of a  tax
assessment.

         Since fiscal 2003, we have been recording a full valuation  allowance
against our future  income tax assets  because it is more likely than not that
these assets will not be recovered.  The valuation  allowance will be reversed
once  management  will have  concluded  that  realization of future income tax
assets  is more  likely  than  not.  Consequently,  our  income  tax rates are
distorted compared to statutory rates.


NET EARNINGS (LOSS) AND PRO FORMA NET EARNINGS (LOSS)

         Net earnings  amounted to $9,000 for the three months ended  February
28,  2005,  compared  to a net loss of $2.9  million  for the same period last
year.  In terms of per share  amounts,  we recorded net earnings of nil in the
second  quarter of fiscal  2005,  compared to a net loss of $0.04 for the same
period last year.

         Net loss amounted to $2.4 million and $4.9 million for the first half
of fiscal  2005 and 2004,  respectively.  In terms of per  share  amounts,  we
recorded a net loss of $0.03 and $0.08 for the first  half of fiscal  2005 and
2004, respectively.

         Also, as a measure to assess financial performance,  we use pro forma
net earnings (loss) and pro forma net earnings (loss) per share. Pro forma net
earnings   (loss)   represent  net  earnings  (loss)   excluding   stock-based
compensation costs,  amortization of intangible assets,  restructuring charges
as well as unusual tax recovery.


                                                                            11


         Pro forma net earnings  amounted to $1.5 million for the three months

$3.6 million, or $0.06 per share for the same period last year.

         One of the three main  objectives of our fiscal 2005  strategic  plan
was to  maximize  profitability.  We believe  that such an  objective  will be
achieved by being  profitable  on a pro forma basis.  As shown  above,  in the
first half of fiscal  2005,  we reported  pro forma net  earnings of $718,000,
which is a step in the right direction.

         We disclose pro forma financial data in order to provide supplemental
information  regarding our results of operations and to enhance our investors'
overall  understanding of our core financial performance and our prospects for
the future.  We believe  that our  investors  benefit  from seeing our results
through the eyes of  management  in  addition to seeing the GAAP  information.
This  non-GAAP  information  facilitates  management's  comparison  of current
results with the company's historical results of operations and strategic plan
and with those of our peers. This information is not in accordance with, or an
alternative  to, GAAP and should be  considered  in addition  to, but not as a
substitute for, other measures of financial performance reported in accordance
with GAAP, such as net earnings (loss). As a result, our pro forma net


                                                                            12


earnings (loss) may not be comparable to similarly titled measures reported by
other companies.


LIQUIDITY AND CAPITAL RESOURCES

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

         As at February 28, 2005, cash and short-term investments consisted of
$98.8 million,  while our working  capital was at $123.2  million.  During the
second quarter of fiscal 2005, our cash and short-term  investments  increased
$4.2  million  due to cash  flows from  operating  activities.  However,  this
increase in cash and short-term investments was mostly offset by an unrealized
foreign exchange loss of $3.9 million on cash and short-term  investments,  as
the Canadian  dollar dropped  slightly this quarter,  and by the cash payments
for the purchase of property,  plant and equipment of $246,000. The unrealized
foreign  exchange  loss  resulted  from the  translation  in US dollars of our
Canadian-dollar-denominated  cash and short-term investments, and was recorded
in the cumulative translation adjustment in the balance sheet.

         We  believe  that  our  cash  balances  and  short-term  investments,
combined with an available line of credit of $3.4 million,  will be sufficient
to meet our liquidity and capital  requirements  for the  foreseeable  future.
However, possible additional operating losses and/or possible investment in or
acquisition of complementary businesses,  products or technologies may require
additional financing. There can be no assurance that additional debt or equity
financing will be available when required or, if available,  it can be secured
on satisfactory terms. Our line of credit bears interest at prime rate.

OPERATING ACTIVITIES

         Cash flows provided by operating activities were $4.2 million for the
three  months ended  February 28, 2005,  compared to $1.6 million for the same
period last year.  Cash flows  provided by operating  activities in the second
quarter of fiscal  2005 were mainly  attributable  to the net  earnings  after
items not  affecting  cash of $3.3  million  and the  positive  net  change in
non-cash  operating items of $830,000.  During the second quarter of 2005, our
income taxes and tax credits recoverable  decreased $1.9 million following the
recovery of tax credits earned in previous  years.  However,  during that same
period,  our  inventories  increased  $1.0  million  in order to  sustain  our
increased sales activities.

         Cash flows provided by operating activities were $4.6 million for the
six  months  ended  February  28,  2005,  compared  to cash flows used of $1.4
million  for the same  period  last year.  Cash flows  provided  by  operating
activities  in the first half of fiscal 2005 were mainly  attributable  to the
net earnings  after items not affecting  cash of $3.6 million and the positive
net change in non-cash operating items of $1.0 million. During the second half
of fiscal 2005,  our income taxes and tax credits  recoverable  decreased $2.3
million for the above-mentioned reason. Also, our accounts payable and accrued
liabilities increased by $377,000 due to the increased level of activities. On
the other hand,  our  inventories  increased $1.9 million due to our increased
sales activities.


                                                                            13



INVESTING ACTIVITIES

         Cash flows used by  investing  activities  were $4.9  million for the
three months ended  February 28, 2005,  compared to $31.5 million for the same
period last year.  In the second  quarter of fiscal  2005,  we  acquired  $4.6
million  worth of  short-term  investments  with  cash  flows  from  operating
activities  and  paid  $246,000  for  the  purchase  of  property,  plant  and
equipment.  For the corresponding  period last year, we acquired $31.3 million
worth of short-term  investments  with the net proceeds of the public offering
completed during that quarter and cash flows from operating activities.

         Cash flows used by investing activities were $6.2 million for the six
months ended February 28, 2005,  compared to $29.0 million for the same period
last year. In the first half of fiscal 2005, we acquired $5.4 million worth of
short-term  investments  with cash flows from  operating  activities  and cash
on-hand and paid $823,000 for the purchase of property,  plant and  equipment.
For the  corresponding  period last year,  we acquired  $28.4 million worth of
short-term  investments  with the net proceeds of the public offering and paid
$576,000 for the purchase of property, plant and equipment.


FORWARD EXCHANGE CONTRACTS

         We utilize forward exchange  contracts to manage our foreign currency
exposure.  Our policy is not to utilize those derivative financial instruments
for trading or speculative purposes.

         Our forward exchange  contracts,  which are used to hedge anticipated
US-dollar-denominated sales, qualify for hedge accounting;  therefore, foreign
exchange  translation gains and losses on these contracts are recognized as an
adjustment of the revenues when the corresponding sales are recorded.

         As at February 28, 2005, we held forward  exchange  contracts to sell
US dollars at various forward rates, which are summarized as follows:



                                                  CONTRACTUAL   WEIGHTED AVERAGE CONTRACTUAL

     March 2005 to August 2005                 $        7,800                       1.3663
     September 2005 to November 2007                   19,600                       1.2862


         As at February 28, 2005, these forward exchange  contracts  generated
deferred  unrealized gains of US$1.7 million.  Deferred  unrealized gains were
calculated  using an exchange  rate of Cdn$1.2316 = US$1.00 as at February 28,
2005.


CONTINGENCY

         As  discussed  in  note  8  to  our  interim  consolidated  financial
statements,  the company was named as a defendant in a U.S.  securities  class
action  related  to its  initial  public  offering  (IPO)  in June  2000.  The
complaints  allege that the prospectus and the registration  statement for the
IPO failed to disclose  that the  underwriters  allegedly  received  excessive
commissions and that the underwriters and some investors collaborated in order
to inflate the price of EXFO's stock in the after-market.


                                                                            14


         In June  2003,  a  committee  of the  company's  Board  of  Directors
conditionally  approved a proposed  settlement  between the issuer defendants,
the individual  defendants,  and the plaintiffs.  If approved,  the settlement
would  provide,  among  other  things,  a release  of the  company  and of the
individual  defendants for the conduct alleged in the action to be wrongful in
the  amended   complaint.   The  company   would  agree  to  undertake   other
responsibilities under the settlement,  including agreeing to assign away, not
assert,  or release certain  potential claims the company may have against its
underwriters.  Any  direct  financial  impact of the  proposed  settlement  is
expected to be borne by the company's insurance carriers.

         On June 25, 2004, the Plaintiffs  moved for  Preliminary  Approval of
the settlement,  and the Underwriter  defendants have opposed that motion. The
court granted the preliminary approval motion on February 15, 2005, subject to
certain  modifications.  The parties are  directed to report back to the court
regarding  the  modifications.  If the  parties  are  able to  agree  upon the
required  modifications,  and such  modifications are acceptable to the court,
notice  will be given to all class  members of the  settlement,  a  "fairness"
hearing will be held and if the court  determines  that the settlement is fair
to the  class  members,  the  settlement  will be  approved.  There  can be no
assurance that this proposed  settlement  will be approved and  implemented in
its current  form,  or at all.  Therefore,  it is not  possible to predict the
final outcome of the case, nor determine the amount of any possible losses. If
the settlement process fails, the company will continue to defend its position
in this litigation  that the claims against it, and its officers,  are without
merit.  Accordingly,  no provision  for this case has been made in our interim
consolidated financial statements as at February 28, 2005.


SHARE CAPITAL AND STOCK-BASED COMPENSATION PLANS

SHARE CAPITAL

         As at April 1,  2005,  EXFO had  37,900,000  multiple  voting  shares
outstanding,  entitling to ten votes each and  30,648,774  subordinate  voting
shares  outstanding.  The multiple  voting shares and the  subordinate  voting
shares are unlimited as to number and without par value.

STOCK OPTION PLAN

         During the three  months ended  February  28, 2005,  EXFO amended its
stock option plan to include the award of Restricted Stock Units (RSUs).  Each
RSU  entitles  employees  to receive  one  subordinate  voting  share  without
consideration  on the vesting dates  established  by the Board of Directors of
EXFO, subject to a minimum term of three years and a maximum term of ten years
from the award  date.  RSUs  granted  under the plan  expire at the latest ten
years  from the date of grant.  The  aggregate  number of  subordinate  voting
shares  covered by RSUs granted  under the stock option plan was 176,185 as at
February 28, 2005. In addition,  the aggregate  number of  subordinate  voting
shares covered by options granted under the stock option plan was 2,842,949 as
at February  28,  2005.  The weighted  average  exercise  price of those stock
options  was  $12.94  compared  to the  market  price of $4.70 per share as at
February 28, 2005.

         Finally,  during the three  months  ended  February  28,  2005,  EXFO
established a Deferred  Stock Unit (DSUs) plan for the members of the Board of
Directors as part of their annual  retainer fees.  Each DSU entitles the Board
members to receive one subordinate voting share. DSUs are acquired on the date
of grant and will be  redeemed  in  subordinate  voting  shares when the Board
member will cease to be  Director  of the  company.  The  aggregate  number of


                                                                            15


subordinate voting shares covered by DSUs granted under the plan was 10,930 as
at February, 28, 2005.

         The following tables summarize  information about stock options, RSUs
and DSUs  granted to the members of the Board of Directors  and to  Management
and Corporate  Officers of the company and its subsidiaries as at February 28,
2005:

RISKS AND UNCERTAINTIES

         Over the past few years,  we have managed our business in a difficult
environment;  focused  on  research  and  development  programs  for  new  and
innovative products aimed at expected growth pockets in our sector;  continued
the development of our domestic and international  markets; and made strategic
acquisitions.  However,  we operate in a highly  competitive sector 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.

         Firstly,  we are exposed to  currency  risks due to the export of our
Canadian-manufactured products, the large majority of which are denominated in
US dollars for sale.  These risks are partially  hedged by operating  expenses
denominated  in US dollars,  the  purchase of raw  materials in US dollars and
forward exchange contracts. The increased


                                                                            16


strength of the Canadian dollar,  compared to the US dollar, over the last two
years caused our operating expenses,  as well as our foreign exchange loss, to
increase.  Any  further  increase in the value of the  Canadian  dollar in the
coming months will negatively affect our results of operations.

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

         In addition,  given our  strategic  goals for growth and  competitive
positioning in our industry, we are continuously  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 strategic acquisitions, like those we have made in
the past and possibly  others in the future,  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.

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