EXFO INCREASES SALES AND BOOKINGS FOR A FIFTH CONSECUTIVE QUARTER

o    REACHED US$21.6 MILLION AND US$23.3 MILLION IN SALES AND BOOKINGS,
     RESPECTIVELY

o    GENERATED 42.7% OF SALES FROM PRODUCTS ON THE MARKET TWO YEARS OR LESS

o    ENHANCED PROTOCOL TEST OFFERING WITH NEXT-GENERATION SONET/SDH AND VOIP/IP
     VIDEO TEST FUNCTIONALITIES

QUEBEC CITY, CANADA, January 12, 2005--EXFO  Electro-Optical  Engineering Inc.
(NASDAQ:  EXFO;  TSX:  EXF.SV)  reported today sales and bookings growth for a
fifth consecutive quarter.

Sales  increased  35.3% to US$21.6 million in the first quarter ended November
30, 2004,  from US$16.0  million in the first  quarter of fiscal 2004 and 1.2%
from US$21.3  million in the fourth  quarter of 2004.  Net bookings  increased
37.9% to US$23.3  million in the first  quarter  of fiscal  2005 from  US$16.9
million in the same  period  last year and 14.2% from  US$20.4  million in the
fourth quarter of 2004.

Gross margin  accounted for 52.7% of sales in the first quarter of fiscal 2005
compared to 51.0% in the first quarter of 2004 and 55.1% in the fourth quarter
of 2004.

GAAP net loss in the first quarter of fiscal 2005 totaled US$2.4  million,  or
US$0.03 per share,  compared to US$2.0  million,  or US$0.03 per share, in the
same period last year and US$2.3 million,  or US$0.03 per share, in the fourth
quarter  of 2004.  On a pro forma  basis*,  net loss in the first  quarter  of
fiscal 2005 amounted to US$814,000,  or US$0.01 per share,  compared to US$2.1
million, or US$0.03 per share in the first quarter of 2004 and net earnings of
US$1.4 million, or US$0.02 per share, in the fourth quarter of 2004.

Included in the GAAP and pro forma figures of the first quarter of fiscal 2005
is a  foreign-exchange  loss of  US$1.0  million  due to the  strength  of the
Canadian dollar versus the US dollar.

"I am really pleased with our fifth consecutive  quarter of sales and bookings
growth,   increases  in  the  mid-30%  range  for  these  respective   metrics
year-over-year and the recent contract win with an additional  US-based Tier-1
network service  provider," said Germain Lamonde,  EXFO's Chairman,  President
and  CEO.  "On the  strength  of our  continued  R&D  investments,  leadership
position  in  the  fiber-to-the-whatever  (FTTx)  market,  differentiated  new
protocol test offering,  and increased sales and marketing  intensity,  we are
confident of achieving our targeted sales growth of 20% year-over-year."

"The sudden 10% increase of the Canadian dollar in the last quarter  certainly
affected  our  profitability,  even with our hedging  policies,"  Mr.  Lamonde
added.  "Nevertheless,  we remain more than ever  committed  to  returning  to
profitability on a pro forma basis in fiscal 2005."

OPERATING EXPENSES

Selling and  administrative  expenses amounted to US$7.4 million,  or 34.3% of
sales,  for the first  quarter of fiscal 2005 compared to US$5.9  million,  or
36.7% of sales, for the same period last year and US$6.3 million,  or 29.8% of
sales, for the fourth quarter of 2004.

Gross research and development  expenses  totaled US$3.8 million,  or 17.6% of
sales,  in the first  quarter of fiscal 2005  compared to US$3.6  million,  or
22.4% of sales, in the first quarter of 2004 and US$3.6  million,  or 17.0% of
sales, in the fourth quarter of 2004.

FIRST-QUARTER BUSINESS HIGHLIGHTS

     o   Confirming its leadership  position in the rapidly  growing FTTx test
         market, EXFO shipped several  FTTx-related orders to a Tier-1 network
         service  provider who accounted for 25.0% of total sales in the first
         quarter of 2005.  Subsequent to the quarter-end,  EXFO also announced
         that a suite of FTTx  products  has been  certified by a second major
         US-based  network service provider on an exclusive basis for the next
         four years.

     o   Leveraging its ongoing R&D investments,  EXFO launched seven products
         in the first quarter of 2005,  including a next-generation  SONET/SDH
         analyzer  for testing IP networks,  an Ethernet  test  solution  with
         voice-over-IP  (VoIP)  test  capabilities,  and an  optical  spectrum
         analyzer  for  coarse   wavelength   division   multiplexing   (CWDM)
         applications  in metro and access  networks.  Sales from new products
         that have been on the market two years or less rose to 42.7% of sales
         in the first quarter of 2005.

     o   EXFO's ongoing  efforts to renew with  profitability  were impeded in
         the first quarter of 2005 by a 9.6%  increase in the Canadian  dollar
         versus the US dollar.  This rapid and  significant  increase not only
         generated a foreign-exchange  loss of US$1.0 million, but also flowed
         through  EXFO's  entire  statement  of earnings  since a  significant
         amount  of  the  company's  operating  expenses  are  denominated  in
         Canadian dollars.


BUSINESS OUTLOOK

EXFO forecasts  sales between  US$21.0  million and US$24.0 million and a GAAP
net loss  between  US$0.03  and  US$0.00  per share for the second  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  loss/earnings  between a loss of US$0.01  per
share and earnings of US$0.02 per share.

                  (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  November  30,  2004,  and  for  the
     three-month  periods ended  November 30, 2003 and 2004, is unaudited.  In
     the opinion of management,  all  adjustments  necessary to present fairly
     the  results  of these  periods in  accordance  with  generally  accepted
     accounting principles in Canada have been included.  The adjustments made
     were of a normal recurring nature. Interim results may not necessarily be
     indicative of results anticipated for the entire year.

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


2    NEW ACCOUNTING STANDARDS

     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  Statements  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.


3    RESTRUCTURING AND OTHER CHARGES

     During the three months ended  November  30, 2004,  the company  incurred
     $200,000 in  restructuring  charges to continue the  consolidation of the
     Photonics and Life  Sciences  Division.  The company  expects to incur an
     additional  $800,000  mainly in the second and third  quarters  of fiscal
     2005 for a total of $2,700,000 in charges  related to this  consolidation
     process.

7     INCOME TAXES

      During the three months ended  November 30, 2004,  the company  recorded
      income  taxes of  $725,000,  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. Approximately 300 other issuers and their
      underwriters have had similar suits filed against them, all of which are
      included in a single coordinated  proceeding in the Southern District of
      New York (the "IPO

     Litigations").  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 two amended  complaints:  one
     containing master allegations  against all of the underwriters in the IPO
     Litigations, and the other 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.  The
     Court granted the company's motion to dismiss the claims against it under
     Section 11 of the Securities  Act. The Court denied the company's  motion
     to dismiss the claims  against it under Rule 10b-5.  In October 2002, the
     claims against its officers were dismissed without prejudice  pursuant to
     the terms of the  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.  On June 25,
     2004, the Plaintiffs  moved for  Preliminary  Approval of the settlement,
     and the Underwriter defendants have opposed that motion. 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.

     Since the settlement  process is subject to a fairness  hearing and final
     court approval, it is possible that it could fail.  Therefore,  it is not
     possible  to predict the final  outcome of the case,  nor  determine  the
     amount of any possible  losses.  If the  settlement  process  fails,  the
     company will continue to defend its position in this  litigation that the
     claims against it, and its officers, are without merit. Accordingly, no

     provision  for  this  case has been  made in the  consolidated  financial
     statements as at November 30, 2004.

      Stock options excluded from the calculation of the diluted weighted
          average number of shares because their exercise price was greater than

     The diluted  loss per share for the periods  ended  November 30, 2003 and
     2004, was the same as the basic loss per share since the dilutive  effect
     of stock  options and  restricted  stock awards should not be included in
     the   calculation;   otherwise,   the  effect  would  be   anti-dilutive.
     Accordingly,  diluted  loss per share for those  periods  was  calculated
     using the basic weighted average number of shares outstanding.

     RESEARCH AND DEVELOPMENT TAX CREDITS

     During the three  months ended  November 30, 2003 and 2004,  net research
     and  development  expenses  under Canadian GAAP included tax credits that
     are  refundable   against   taxable  income  of  $400,000  and  $582,000,
     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.


     STATEMENTS OF CASH FLOWS

     For the three  months  ended  November  30, 2003 and 2004,  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 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 abnormal amounts of idle
     facility   expense,   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

         The global telecommunications market environment continued to improve
in the  first  quarter  of  fiscal  2005,  especially  in the  United  States,
following a major announcement by the Federal Communications Commission (FCC).
The FCC, which regulates the telecommunications industry in the United States,
ruled that  network  service  providers  (NSPs)  will not have to share  their
optical links (at reduced  prices) with other  carriers for  fiber-to-the-curb
(FTTC) and  fiber-to-the-node  (FTTN)  deployments  as it had done earlier for
fiber-to-the-premises (FTTP) deployments.  These latest announcements prompted
immediate  responses by U.S.-based,  Tier-1 NSPs, who publicly  announced they
will accelerate their fiber deployments deeper into access networks.


                                                                               1



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 a worldwide  phenomenon.  NSPs, on a
global basis,  are turning to a single,  IP-based  network  architecture  that
carries voice, data and video services in order to drastically reduce costs.

         These key market  trends  affected  multiple  segments  of the global
telecommunications  supply  chain.  System  manufacturers  benefited  from NSP
orders for  next-generation,  converged IP networks and fiber  deployments  in
access areas.  Component vendors began seeing  incremental  demand for optical
components that support IP-based systems.  Some test and measurement equipment
vendors,  whose  products  enable  customers  to reduce  capital  expenditures
(CAPEX) and operating expenses (OPEX), attracted the attention of NSPs, system
manufacturers and component  vendors,  especially ones offering test solutions
for IP optical networking and/or FTTx (FTTP, FTTC, FTTN) applications.


COMPANY OVERVIEW

         Sales  reached  $21.6  million in the first quarter of 2005, of which
25.0% was shipped to a U.S.-based, Tier-1 NSP. Historically,  sales to our top
customer represented less than 10% of total sales on a quarterly basis, but in
two of the last three quarters, one customer has accounted for more than 25.0%
of our sales.

         We believe this  unusual  sales  concentration  is largely due to our
leadership  position in the FTTx test market.  A number of NSPs are initiating
major  deployments  of FTTx  networks  in order to offer  their  end-customers
bundled voice, data and video services.

         In the  first  quarter  of 2005,  we  launched  seven  new  products,
including a  next-generation  SONET/SDH  analyzer for testing  data-centric IP
networks,  a Gigabit  Ethernet test solution  with  voice-over-IP  (VoIP) test
capabilities,  and an optical  spectrum  analyzer (OSA) for coarse  wavelength
division multiplexing (CWDM) applications in metro and access networks.

         We recorded a foreign  exchange  loss of $1.0  million,  or $0.02 per
share, due to the significant  depreciation of the US dollar,  compared to the
Canadian  dollar  during the first quarter of fiscal 2005. In addition to this
foreign  exchange  loss, our P&L line items were also  negatively  affected by
this  depreciation of the US dollar a significant  portion of our expenses are
incurred in Canadian dollars and we report our results in US dollars.

         We  incurred  $200,000  in  restructuring  charges  to  continue  the
consolidation of our Photonics and Life Sciences Division in the first quarter
of 2005. We had sustained $1.7 million in  restructuring  and other charges in
the fourth  quarter of 2004 and we expect to incur an  additional  $800,000 in
the second and third  quarter  of 2005 for a total of  $2.7million  in charges
related to this  consolidation  process.  We estimate that we will derive $1.5
million in annual savings from these streamlined operations.

         During  the first  quarter of fiscal  2005,  some  conditions  of the
formal offer to buy one of our  buildings,  received at the  beginning of this
quarter,  were  not  met and  this  offer  has  been  declined.  Consequently,
management has decided to withdraw the building from the market.


                                                                               2

SALES

         For the three  months  ended  November  30,  2004,  our global  sales
increased  35.3% to $21.6  million from $16.0 million for the same period last
year, with an 81%-19% split in favor of our Telecom Division.


TELECOM DIVISION

         For the three  months ended  November 30, 2004,  sales of our Telecom
Division  increased  43.6% to $17.4  million  from $12.1  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  (FTTx),  in particular from a U.S.-based,  Tier-1
NSP customer,  who accounted for 31% of our telecom sales in this quarter.  In
addition,  the positive  spending  environment  helped us increase  sales this
quarter.

         Over the last few  months,  we have been  offering  new and  enhanced
extented-warranty     programs,     which    significantly    increased    our
extended-warranty sales. Revenues from these sales are deferred and recognized
over the warranty period, causing our deferred revenue in the balance sheet to
increase.


PHOTONICS AND LIFE SCIENCES DIVISION

         For the three months ended November 30, 2004,  sales of our Photonics
and Life Sciences  Division  increased  9.1% to $4.2 million from $3.8 million
for the same period last year.  The  increase in sales is due to market  share
gain in the illumination market.

         Overall, for the two divisions,  net accepted orders increased 38% to
$23.3  million in the first  quarter of fiscal 2005 from $16.9 million for the
same period last year. The slight improvement in the telecommunications market
environment,  the  increased  demand  for our FTTx test  solutions  as well as
market-share gains in the  telecommunications and life sciences markets helped
us increase our bookings  year-over-year.  Our net book-to-bill  ratio rose to
1.08 in the first quarter of 2005, from 1.06 for the same period last year. In
the previous quarter, the net book-to-bill ratio reached 0.96.


GEOGRAPHIC DISTRIBUTION

         For the three months ended November 30, 2004,  sales to the Americas,
Europe-Middle  East-Africa  (EMEA)  and  to  the  Asia-Pacific  (APAC)  region
accounted  for  71%,  18%  and  11% of  global  sales,  respectively.  For the
corresponding period last year, sales to the Americas, EMEA and APAC accounted
for 65%, 17% and 18% of global sales, respectively. Our sales to the Americas,
which increased 48%  year-over-year,  benefited from the recent deployments of
fiber deeper into the access networks,  which, as mentionned  above,  occurred
mainly in the United States.  Our sales to EMEA also  increased  significantly
(47%) year-over-year,  mainly due to market share gains in both divisions. Our
sales to APAC  decreased 19%  year-over-year.  Most of our sales to this maket
are made through  tenders that may vary in number and importance  from quarter
to quarter.

         Through our two  divisions,  we sell our products to a broad range of
customers, including NSPs, optical component and system manufacturers, as well
as  high-tech   industrial   manufacturers   and   research  and   development
laboratories. During the three months ended November 30, 2004, a large portion
of our sales was attributed to a single customer,  accounting for 25.0% of our
total sales. During that same period, our top three customers accounted for


                                                                               5



30.6% of sales. For the corresponding  period last year, no customer accounted
for more than 8.4% of sales and our top three customers accounted for 17.0% of
sales.

         Considering  the sales level and the net  book-to-bill  ratio for the
first quarter 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 52.7% of sales for the three  months ended
November 30, 2004, compared to 51.0% for the same period last year.

         The 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 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, to some extent,  from further improving our gross margin as some
cost of sales  elements are  denominated  in Canadian  dollars.  Finally,  the
customer mix and pricing pressure observed in the first quarter of fiscal 2005
also prevented us from further improving our gross margin.

         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 additional
increase in the strength of the Canadian  dollar over the next  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  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   November  30,  2004,   selling  and
administrative expenses were $7.4 million, or 34.3% of sales, compared to $5.9
million, or 36.7% 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 additional personal), resulting from our
strategic  decision  to  expand  our  sales  organization  in order 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  as well as
expenses related to compliance with the Sarbanes-Oxley Act of 2002 were higher
than in  fiscal  2004,  further  increasing  our  selling  and  administrative
expenses year-over-year. However, we were able to mitigate the increase in our
selling and administrative


                                                                               6



expenses  as well  as  reduce  our  selling  and  administrative  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 and be  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  November  30,  2004,  gross  research and
development expenses totaled $3.8 million, or 17.6% of sales, compared to $3.6
million, or 22.4% of sales for the same period last year.

         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   year-over-year.
Nonwithstanding  the  increased  strength of the  Canadian  dollar,  our gross
research and  development  expenses  would have decreased  year-over-year  (in
absolute dollar amount),  mainly due to the mix and timing of R&D projects and
the  consolidation  of our R&D activities.  The decrease in our gross research
and development  expenses, as a percentage of sales is directly related to the
significant increase in our sales year-over-year.

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

         For the three months ended  November 30, 2004, tax credits and grants
from  the  Canadian  federal  and  provincial  governments  for  research  and
development  activities  were $1.0  million,  or 26.8% of gross  research  and
development  expenses,  compared to $744,000,  or 20.8% 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.

         In the first  quarter of fiscal 2005,  43% of sales  originated  from
products  that have been on the  market  for two years or less.  For the first
quarter of 2004, this number reached 38% of sales. The 2005 figure is slightly
below 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 seven new ones  lauched in the
first quarter of fiscal 2005, we remain confident that we will achieve our KPI
of 45% for fiscal 2005.


                                                                               7



         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 to exceed  customer
needs and expectations.

AMORTIZATION OF PROPERTY, PLANT AND EQUIPMENT

         For the  three  months  ended  November  30,  2004,  amortization  of
property,  plant and equipment was $1.1 million,  compared to $1.3 million for
the  same  period  last  year.  The  decrease  in  the  amortization   expense
year-over-year,  despite the significant  increase in the strength of Canadian
dollar  compared  to the US dollar,  is mainly due to the fact the some of our
property, plant and equipment have become fully amortized during fiscal 2004.

RESTRUCTURING CHARGES

         For the three months ended November 30, 2004,  restructuring  charges
amounted to $200,000.  These  charges were  recorded in  conjunction  with the
transfer of EXFO Burleigh's  operations mainly to Toronto.  This consolidation
process started in the last quarter of fiscal 2004 and will extend through the
third quarter of 2005.  In the first quarter of 2004, we had no  restructuring
charges.

INTEREST AND OTHER INCOME

         For the three months ended  November  30, 2004,  interests  and other
income  amounted to  $724,000,  compared to $156,000  for the same period last
year.  During the first  quarter  of fiscal  2005,  we finally  cashed R&D tax
credits claimed in fiscal 2001 and we were granted $162,000 in interest by the
tax  authorities.  In addition,  our  interest  income was higher in the first
quarter of 2005 than during the same period last year  because of the increase
in our cash position  following  our public  offering in February 2004 and the
increase in interest  rates.  Furthermore,  in the first  quarter of 2005,  we
recorded $125,000 for sale of excess assets.  Finally, in the first quarter of
fiscal 2004, we recorded an interest  expense of $169,000 in relation to a tax
assessment.

FOREIGN EXCHANGE LOSS

         For the three months ended  November 30, 2004,  the foreign  exchange
loss amounted to $1.0  million,  compared to $470,000 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 November 30, 2004, the Canadian  dollar
value increased  significantly and rapidly compared to the US dollar (increase
of CA$0.13, or 9.6%),  resulting in a significant foreign exchange loss during
this quarter. During the same period last year, the Canadian dollar value also
increased  significantly  compared to the US dollar  (increase of CA$0.09,  or
6.3%), resulting in a significant but less important exchange loss during that
period.  The  increase  in  our  foreign  exchange  loss  year-over-year,   in
percentage, was greater than the increase in the value of the Canadian dollar,
in  percentage,  as we had a higher level of activity in the first  quarter of
fiscal 2005, compared to the same period last 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


                                                                               8



dollar,  compared to the US dollar, will continue to have a negative impact on
our operating results.

INCOME TAXES

         For the three months ended  November 30, 2004,  we recorded an income
tax expense of  $725,000,  compared to an income tax  recovery of $1.5 million
for the same  period last year.  The income tax expense  recorded in the first
quarter of fiscal 2005  represented  income taxes payable in some specific tax
jurisdictions. The income tax recovery recorded in the first quarter of fiscal
2004 was mainly due to the $1.4 million unusual  recovery of income taxes paid
in previous periods.

         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 future periods' income tax
rates will be distorted compared to statutory rates.

NET LOSS AND PRO FORMA NET LOSS

         Net loss  amounted  to $2.4  million  and $2.0  million for the three
months ended November 30, 2004 and 2003,  respectively.  In terms of per share
amounts,  we recorded a net loss of $0.03 for each of the three  months  ended
November 30, 2004 and 2003, respectively.

         Also, 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  stock-based  compensation  costs,  amortization  of intangible
assets, restructuring charges as well as an unusual income tax recovery.

         Pro forma net loss  amounted  to  $814,000  and $2.1  million for the
three months ended November 30, 2004 and 2003,  respectively.  In terms of pro
forma per share  amounts,  we  recorded  a net loss of $0.01 and $0.03 for the
three months ended November 30, 2004 and 2003, respectively.

         Pro forma net loss is reconciled as follows:



                                                                 THREE MONTHS ENDED NOVEMBER 30,

         One  of the  three  main  objectives  of our  strategic  plan  was to
maximize profitability.  We believe that such an objective will be achieved by
being profitable on a pro forma basis. In the first quarter of fiscal 2005, we
fell short of our  objective,  mainly  because of the  negative  impact of the
increased strength of the Canadian dollar.  However,  we remain confident that
we will attain this strategic objective for fiscal 2005.

         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 loss.  As a result,  our pro forma net 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 November 30, 2004 cash and short-term  investments consisted of
$98.6 million,  while our working capital was at $126.8 million.  Our cash and
short-term  investments  increased  $9.4 million  compared to August 31, 2004,
mainly due to an unrealized  foreign exchange gain of $9.3 million on cash and
short-term  investments  as well as cash flows from  operating  activities  of
$479,000.  However, the increase in cash and short-term  investment was offset
in part by the cash  payments of $577,000 for the purchase of property,  plant
and  equipment.  The  unrealized  foreign  exchange  gain  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 $5.5 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  $479,000 for the
three  months ended  November  30,  2004,  compared to cash flows used of $3.0
million  for the same  period  last year.  Cash flows  provided  by  operating
activities in the first quarter of fiscal 2005 were mainly attributable to the
net earnings  after items not affecting  cash of $315,000 and the positive net
change in non-cash operating items of $164,000.


                                                                              10



INVESTING ACTIVITIES

         Cash flows used by  investing  activities  were $1.3  million for the
three months ended November 30, 2004,  compared to cash flows provided of $2.5
million for the same period last year. In the first quarter of fiscal 2005, we
sold  $756,000  worth of  short-term  investments  and paid  $577,000  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  January  5,  2005,  we held  contracts  to sell US  dollars at
various forward rates, which are summarized as follows:



                                                                               WEIGHTED AVERAGE 
EXPIRY DATES:                            CONTRACTUAL AMOUNTS          CONTRACTUAL FORWARD RATES
                                         -------------------          -------------------------
                                                                   
    January 2005 to August 2005                        7,200                             1.4217
    September 2005 to November 2007                   14,400                             1.3030



         As at January 5, 2005,  these forward  exchange  contracts  generated
deferred  unrealized gains of US$2.1 million.  Deferred  unrealized gains were
calculated using exchange rate of CA$1.2252 = US$1.00 as at January 5, 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 aftermarket.

         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.  On  June  25,  2004,  the
Plaintiffs  moved  for  Preliminary  Approval  of  the  settlement,   and  the
Underwriter  defendants have opposed that motion. 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.


                                                                              11



         Since the  settlement  process is subject to a fairness  hearing  and
final court approval, it is possible that it could fail. Therefore,  it is not
possible to predict the final outcome of the case, nor determine the amount of
any  possible  losses.  If the  settlement  process  fails,  the company  will
continue to defend its position in this litigation that the claims against it,
and its officers, are without merit.  Accordingly,  no provision for this case
has been made in the  consolidated  financial  statements  as at November  30,
2004.


SHARE CAPITAL AND STOCK-BASED COMPENSATION PLANS

SHARE CAPITAL

         As at December 31, 2004,  EXFO had 37,900,000  multiple voting shares
outstanding,  entitling to ten votes each and  30,640,349  subordinate  voting
shares  outstanding.  The multiple  voting shares and the  subordinate  voting
shares are unlimited as to number and without par value.

RESTRICTED STOCK AWARD PLAN

         In addition to the stock option plan, we maintain a restricted  stock

voting shares covered by restricted stock awards was 53,592 as at November 30,
2004.  Each  restricted   stock  award  entitles   employees  to  receive  one
subordinate  voting  share at a purchase  price of nil. All  restricted  stock
awards vested on December 20, 2004.

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


                                                                              12



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  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.
