RISKS RELATED TO OUR INDUSTRY AND BUSINESS

IF THE DOWNTURN IN THE TELECOMMUNICATIONS INDUSTRY PERSISTS OR WORSENS, DEMAND
FOR OUR PRODUCTS WILL CONTINUE TO DROP AND, AS A RESULT, IT COULD CONTINUE TO
HAVE A MATERIAL ADVERSE EFFECT ON OUR BUSINESS, RESULTS OF OPERATIONS AND
FINANCIAL CONDITION.

         Due to the downturn in the telecommunications industry and the
uncertainty following the tragic events of September 11, 2001, several
telecommunications carriers lowered their spending for network installations.
Optical equipment manufacturers, in turn, were affected by the downturn and the
subsequent buildup of inventories. These market forces on our customers
contributed to a significant decline in our sales. If the downturn persists or
worsens, demand for our products will drop and, as a result, it could have a
material adverse effect on our business, results of operations and financial
condition.

WE HAVE ADOPTED MEASURES AND MAY CONTINUE TO ADOPT MEASURES THAT ALIGN OUR COST
STRUCTURE TO CHALLENGING MARKET CONDITIONS. IF THE CHALLENGING MARKET CONDITIONS
ARE PROLONGED, IT COULD HAVE MATERIAL ADVERSE LONG-TERM EFFECTS ON OUR BUSINESS,
RESULTS OF OPERATIONS AND FINANCIAL CONDITION.

         We have been forced to re-align our cost structure to market conditions
twice during the past year. On June 27, 2001, we announced the reduction of
non-customer-related expenses, postponement of plans to build a new facility in
the Quebec Metro High-Tech Park, termination of non-core operations at a
subsidiary that specialized in manufacturing fiber-optic temperature sensors,
and reduction of our workforce by 15%. On December 5, 2001, we announced the
lowering of our operating expenses, freeze in employee salaries, and reduction
of our workforce by 10%. These and, if needed, subsequent measures could have
material adverse long-term effects on our business, results of operations and
financial condition if we deplete our pool of highly qualified personnel; if we
are unable to sustain research and development efforts for the launch of new
products; if we are unable to meet the needs of our customers; and if we are not
prepared to ramp up manufacturing when market conditions improve. In addition,
if we fail to adopt and implement adequate and pertinent measures on a timely
basis to align our cost structure to challenging market conditions, it could
have a material adverse long-term effects on our business, results of operations
and financial condition.

WE EXPECT THE PRICE OF OUR EXISTING PRODUCTS TO DECLINE AND IF WE DO NOT REDUCE
OUR MANUFACTURING COSTS OR INTRODUCE NEW PRODUCTS WITH HIGHER MARGINS, OUR GROSS
MARGINS WILL DECLINE AND WE COULD INCUR LOSSES.

         Reduced demand for fiber-optic test, measurement and automation
equipment, in addition to competitiveness in our industry will likely result in
the decline of prices for fiber-optic test, measurement and automation
equipment. These price declines result from factors such as:

         o        increased competition for business;
         o        reduced demand;
         o        a limited number of potential customers;

                                        3



         o        competition from companies with lower labor and production
                  costs;
         o        introduction of new products by competitors;
         o        greater economies of scale for higher-volume competitors; and
         o        resale of used equipment.

         As prices of our existing products are expected to decline, we may have
to increase our unit volume sold in order to maintain our existing sales level.
Our increased production capacity results in an increase in fixed costs. As a
result, we will have to increase the level of sales to maintain operating
margins. If we are unable to increase the level of sales, continuously reduce
our manufacturing costs or introduce new products with higher margins, our gross
margins will decline.

OUR QUARTERLY OPERATING RESULTS ARE SUBJECT TO SIGNIFICANT FLUCTUATIONS AND YOU
SHOULD NOT RELY ON THEM AS AN INDICATION OF OUR FUTURE PERFORMANCE.

         Our sales and operating results have fluctuated from quarter to quarter
in the past and may fluctuate significantly in the future. In addition, our
revenue and operating results generally depend on the volume and timing of the
orders we receive from customers as well as our ability to fulfill the orders
received. Our operating expenses, which include research and development, and
selling and administrative expenses, are relatively fixed in the short term. If
our revenue is lower than we expect because we sell fewer products than we
anticipate or if there is a delay in the release of new products, we may not be
able to quickly reduce our operating expenses in response. Factors that could
affect the amount and timing of our revenue, and cause quarterly fluctuations in
our operating results include:

         o        the length of our product sales cycle for certain products,
                  especially those that are higher priced and more complex;
         o        the timing of introduction and market acceptance of new
                  products by us, our competitors or our suppliers;
         o        our ability to sustain product volumes and high levels of
                  quality across all product lines;
         o        the timing of shipments for large orders; and
         o        the effect of potential seasonality in sales.

         Our operating results could also be affected by the following factors,
some of which we have little or no control over:

         o        demand for fiber-optic test, measurement and automation
                  equipment;
         o        changes in the capital budgets of our customers, which may
                  cause seasonal or other fluctuations in the product mix,
                  volume, timing and number of orders we receive from our
                  customers;
         o        difficulties in collecting accounts receivable;
         o        the level of used test, measurement and automation equipment
                  available for resale;
         o        restructuring charges; and
         o        general economic conditions.

         Due to these factors, you should not rely on quarter-to-quarter
comparisons of our results of operations as an indication of our future
performance.

                                        4



IF THE SUPPLY OF HIGH-BANDWIDTH TRANSMISSION NETWORKS SHOULD CONTINUE TO SURPASS
DEMAND, OR IF OPTICAL FIBER IS REPLACED BY ANOTHER MEDIUM AS THE PRIMARY
SOLUTION FOR BANDWIDTH-INTENSIVE APPLICATIONS, WE COULD EXPERIENCE A SIGNIFICANT
LONG-TERM LOSS OF SALES.

         Fiber-optic deployment and network capacity increases have slowed
during recent months which has affected optical component and network equipment
manufacturers and operators causing reduced demand for fiber-optic test,
measurement and automation equipment. If such reduced demand should continue
over the mid or long term, or if optical fiber is replaced by a higher
performance medium, this could have a material adverse effect on our business,
financial condition and results of operations.

IF CUSTOMERS FAIL TO MEET THEIR FINANCIAL COMMITMENTS TO US, IT COULD HAVE A
MATERIAL ADVERSE EFFECT ON OUR BUSINESS, RESULTS OF OPERATIONS AND FINANCIAL
CONDITION.

         The telecommunications industry is undergoing challenging times. Some
companies are shutting down their operations or going bankrupt. On occasion, we
have had customers who failed to meet their financial commitments to us. We
attempt to reduce the possibility of large outstanding bills remaining unpaid by
carrying out credit checks on customers and by having a diversified customer
base. For example, no customer represented more than 6.4% of our sales in the
fiscal year ended August 31, 2001. However, there is no assurance that such
measures will reduce or eliminate our exposure to customer credits risks. If
customers fail to meet their financial commitments to us, it could have a
material adverse effect on our business, results of operations and financial
condition.

AS OUR CUSTOMERS CONSOLIDATE OR ENCOUNTER FINANCIAL DIFFICULTIES, THEY MAY
REDUCE OR HALT PURCHASES OF OUR PRODUCTS, WHICH WOULD CAUSE OUR SALES TO
DECLINE.

         Consolidation in the telecommunications industry could reduce the
number of customers to whom our products could be sold. Some of our customers
have been subject to consolidation or are encountering financial difficulty and
are reducing their orders, renegotiating pricing and obtaining products from a
source other than us, which cause our sales to decline. In addition, as a
result, some of our manufacturer customers may discontinue their relationships
with us.

WE DEVOTE CONSIDERABLE TIME AND RESOURCES TO SECURING NEW CUSTOMERS AND
IMPROVING SALES TO EXISTING CUSTOMERS. IF WE ARE UNSUCCESSFUL, OUR FUTURE
OPERATING RESULTS MAY SUFFER.

         The long sales cycle for some of our products may cause our sales and
operating results to vary significantly from period to period. The period of
time between our initial contact with a customer and the receipt of a purchase
order may span a year or more. In addition, customers perform and require us to
perform, extensive product evaluation and testing of new instruments before
purchasing them. If we are unable to satisfy customer demands, considerable
resources would have been expended without deriving corresponding sales.

OUR CUSTOMERS ARE NOT OBLIGATED TO BUY MATERIAL AMOUNTS OF OUR PRODUCTS AND MAY
CANCEL OR DEFER PURCHASES ON SHORT NOTICE.

         Our customers typically purchase our products under individual purchase
orders and may cancel or defer purchases on short notice without significant
penalty. Accordingly, sales in a particular period are difficult to predict.
Decreases in purchases, cancellations of purchase orders, or deferrals of
purchases may have a material adverse effect on our operating results,
particularly if we do not anticipate them.

                                        5



IF WE FAIL TO PREDICT OUR SUPPLY REQUIREMENTS ACCURATELY, WE WILL HAVE EXCESS
INVENTORY OR INSUFFICIENT INVENTORY, EITHER OF WHICH COULD CAUSE US TO INCUR
ADDITIONAL COSTS, EXPERIENCE MANUFACTURING DELAYS OR INVENTORY OBSOLESCENCE.

         We provide forecasts of our requirements to some of our suppliers up to
six months prior to scheduled delivery of products to our customers. If we
overestimate our requirements, we may have excess inventory, which could
increase our costs and harm our relationships with our suppliers due to reduced
future orders or increase the risk of inventory obsolescence for which eventual
write-offs may become necessary. If we underestimate our requirements, we may
have an inadequate inventory of parts. Inadequate inventory could interrupt
manufacturing of our products and result in delays in shipments. In addition,
lead times for materials and parts that we order may be long and depend on
factors such as the procedures of, or supply terms with, a specific supplier and
demand for each part at a given time.

WE DEPEND ON A SINGLE SUPPLIER OR A LIMITED NUMBER OF SUPPLIERS FOR SOME OF THE
KEY COMPONENTS AND MATERIALS IN OUR PRODUCTS, WHICH MAKES US SUSCEPTIBLE TO
SUPPLY SHORTAGES OR PRICE FLUCTUATIONS THAT COULD ADVERSELY AFFECT OUR OPERATING
RESULTS.

         We depend on a limited number of suppliers for some of the parts used
to manufacture our products. All our orders are placed through individual
purchase orders and, therefore, our suppliers may stop supplying parts to us at
any time. The reliance on a single source or limited number of suppliers could
result in delivery problems and reduced control over product pricing and
quality. Financial difficulties of suppliers could also affect our ability to
obtain necessary parts in a timely manner. The process of qualifying a new
contract manufacturer for complex products, designed to our specifications, such
as our optical and mechanical parts, is lengthy and would consume a substantial
amount of time of our technical personnel and management. If we sought to change
manufacturers in a short period of time, our business would be disrupted. In
addition, we may be unsuccessful in identifying a new manufacturer capable of
and willing to meet our needs on terms that we would find acceptable.

WE MUST CONTINUE TO OVERCOME SIGNIFICANT AND INCREASING COMPETITION IN OUR
INDUSTRY IN ORDER TO GAIN MARKET SHARE AND INCREASE OUR PRODUCTIVITY.

         The market for fiber-optic test, measurement and automation equipment
is rapidly evolving and is marked by intense competition and technical
innovations. We expect the pace of change to accelerate in the future. We also
expect new competitors to emerge or current competitors to consolidate as the
market for fiber-optic test, measurement and automation equipment evolves in
response to technical innovations and economic conditions. Both of these factors
could intensify the competitive pressures that we face.

         Some of our current and potential competitors are global electronic
test and measurement manufacturers who complement their broad range of products
with fiber-optic test, measurement and monitoring equipment. Competitors, such
as Acterna Corporation, Agilent Technologies Inc., ANDO Corporation, Anritsu
Corporation, GN Nettest, Newport Corporation and Tektronix, Inc. may have
greater financial, technical and marketing resources. Consequently, these
competitors may be able to devote greater resources to the development,
marketing, sale and support of their products. They may also be better
positioned than we are to acquire companies and new technologies that may
displace our products or make them obsolete.

IF WE ARE UNABLE TO ADAPT TO CURRENT AND FUTURE CHANGES IN TECHNOLOGY, OUR
PRODUCTS MAY BECOME OBSOLETE.

         Any failure by us to anticipate or respond to new technological
developments and customer requirements could have a material adverse effect on
our business, financial condition and results of

                                        6



operations. Moreover, the markets addressed by our current and planned products
are rapidly evolving and are characterized by emerging standards and competing
technological platforms. There can be no assurance that products destined by us
for sale into these markets will adequately address the requirements dictated by
evolving standards, or that we will be able to adapt our products to changes in
technology. Accordingly, we may invest in products and technologies that never
gain market acceptance. Such investments could have a material adverse effect on
our business, financial condition and results of operations.

WE MAY NOT BE ABLE TO INTRODUCE NEW AND ENHANCED PRODUCTS ON A TIMELY BASIS,
WHICH COULD PREVENT US FROM ACHIEVING OUR GROWTH STRATEGY AND ADVERSELY AFFECT
OUR OPERATING RESULTS.

         The development of proprietary technologies entails significant
technical and business risks and requires substantial expenditures and lead
time. If we experience product delays in the future, we may face:

         o        customer dissatisfaction;
         o        cancellation of orders;
         o        negative publicity;
         o        loss of sales;
         o        slower market acceptance of our products; and
         o        legal actions by customers.

         In the future, our efforts to remedy product delays may not be
successful and we may lose customers as a result. Delays in bringing to market
new products or product enhancements could be exploited by our competitors. If
we lose market share as a result of lapses in our product development, our
business would suffer.

OUR PRODUCTS MAY HAVE UNFORESEEN DEFECTS THAT COULD HARM OUR REPUTATION, IMPEDE
MARKET ACCEPTANCE OF OUR PRODUCTS AND NEGATIVELY IMPACT OUR RESULTS OF
OPERATIONS.

         As a result of their complexity, our products may contain undetected
errors or compatibility problems or regulatory compliance issues, particularly
when they are first introduced or when new versions are released. There can be
no assurance that, despite our testing, errors will not be found in new products
after they have been fully deployed and operated under peak stress conditions.
If we are unable to fix defects or other problems, we could experience, among
other things:

         o        loss of customers;
         o        damage to our brand reputation;
         o        failure to attract new customers or achieve market acceptance;
         o        diversion of development and engineering resources;
         o        legal actions by our customers, including claims for
                  consequential damages and loss of profits; and
         o        legal actions by governmental entities, including actions to
                  impose product recalls and/or forfeitures.

         The occurrence of any one or more of the foregoing could seriously harm
our business, financial condition and results of operations.

                                        7



OUR PRODUCTS MAY BE REQUIRED TO CONFORM TO NEW AND UNFORESEEN REGULATORY
REQUIREMENTS THAT COULD INCREASE OUR COSTS AND REDUCE OUR MARKET SHARE.

         Our products are designed to conform to the regulatory requirements of
the countries in which they are marketed. In the event that the technical
regulations applicable in a given country are in any way changed, we may be
required to modify, redesign or recall some or all of our products in order to
continue participating in that market. These changes likely would increase
manufacturing costs and could create technical advantages for products marketed
by our competitors.

OUR SALES WOULD SUFFER IF A KEY SALES REPRESENTATIVE OR DISTRIBUTOR STOPPED
SELLING OR REDUCED SALES OF OUR PRODUCTS.

         We sell substantially all of our products through a network of
independent sales representatives and distributors, the majority of whom have
exclusive rights to sell our products in specific territories or markets. If we
are unable to provide competitive sales commissions, maintain an appropriate
sales volume, or offer sufficient channel-support, our independent sales
representatives and distributors may discontinue sales of our products and
switch to representing one or more of our competitors, which would result in
reduced sales for us.

WE CANNOT ASSURE THAT WE WILL SUCCESSFULLY INTEGRATE THE BUSINESSES, PRODUCTS,
TECHNOLOGIES OR PERSONNEL OF OUR RECENT AND FUTURE ACQUISITIONS, WHICH MAY HARM
OUR BUSINESS.

         For our past and future transaction to be successful, we must
appropriately integrate the businesses, products, technologies and personnel of
Burleigh Instruments, Inc., EXFO Photonic Solutions Inc., formerly EFOS Inc.,
and EXFO Protocol Inc., formerly Avantas Networks Corporation, and those of any
future acquisitions, with our own business, products, technologies and personnel
in a manner that anticipates or responds to new technological developments and
customer requirements on a timely basis. In addition, we must coordinate the
operations and technologies of newly acquired companies with our own operations
and technologies and manage geographically dispersed operations. Integration
requires the dedication of management resources that may distract their
attention from our day-to-day business and operations. If we fail to integrate
the companies quickly and efficiently, we may not be able to realize the
benefits we expect from these transactions and there could be a material adverse
effect on our business, financial condition and results of operations.

WE MAY NOT BE ABLE TO MAKE THE NECESSARY ACQUISITIONS NEEDED FOR THE DEVELOPMENT
OF OUR BUSINESS AND ANY ACQUISITIONS WE MAKE COULD DISRUPT OUR BUSINESS AND HARM
OUR FINANCIAL CONDITION.

         We intend to seek acquisitions of businesses, products and technologies
that are complementary to ours. There can be no assurance that we will
ultimately make any such acquisition. The consolidation of our competitors may
improve their capacity to acquire the same businesses, products and technologies
that we wish to acquire.

         We have made strategic acquisitions, such as our acquisitions of
Nortech Fibronic Inc., Burleigh, EXFO Photonic and EXFO Protocol. We anticipate
that in the future, as part of our business strategy, we will continue to make
strategic acquisitions of complementary companies, products and technologies. In
the event of any future acquisition, we could:

         o        issue shares that would dilute individual shareholder
                  percentage ownership;
         o        incur debt;
         o        assume liabilities and commitments;

                                        8



         o        incur expenses related to in-process research and development
                  and amortization of other intangible assets; or
         o        incur significant impairment losses of goodwill related to
                  such acquisitions.

         These acquisitions also involve numerous risks, including:

         o        problems combining the acquired operations, technologies or
                  products;
         o        unanticipated costs or liabilities;
         o        diversion of management's attention from our core business;
         o        adverse effects on existing business relationships with
                  suppliers and customers;
         o        risks associated with entering markets in which we have no or
                  limited prior experience; and
         o        potential loss of key employees, particularly those of
                  acquired organizations.

         During the fiscal year ended August 31, 2001, our subsidiary Nortech
Fibronic Inc., acquired in February 2000, shut down its business operations.
Though the impact of this closure is not significant, we cannot assure that we
will be able to successfully integrate the other businesses, products,
technologies or personnel acquired or that we might acquire in the future, and
further divestitures or closures could be necessary which may harm our business.

WE MAY BE SUBJECT TO CERTAIN LIABILITIES ASSUMED IN CONNECTION WITH OUR
ACQUISITIONS THAT COULD ADVERSELY AFFECT OUR BUSINESS.

         We conduct due diligence in connection with our acquisitions and
incorporate indemnification provisions in our acquisition agreements. To the
extent that prior owners of any acquired businesses failed to comply with or
otherwise violated applicable laws, we may be financially responsible for these
violations or otherwise be adversely affected. The discovery of any material
liabilities after the closing of the transaction could have a material adverse
effect on our financial condition and results of operations. In connection with
our acquisition of Burleigh, EXFO Photonic and EXFO Protocol and the acquisition
by Burleigh Automation Inc. of the assets of Vanguard Technical Solutions, Inc.,
there may be liabilities that we failed to discover at the time of the
acquisition or that we inadequately assessed in our due diligence efforts.

IF WE FAIL TO ADAPT APPROPRIATELY TO THE CHALLENGES ASSOCIATED WITH OPERATING
INTERNATIONALLY, THE GROWTH OF OUR BUSINESS MAY BE IMPEDED AND OUR OPERATING
RESULTS MAY BE AFFECTED.

         For the fiscal year ended August 31, 2001, customers outside of the
United States and Canada accounted for 41.7 % of our sales and for the fifteen
months ended November 30, 2001, these customers accounted for 41.8 % of our
sales. We plan to increase our international sales and have opened offices in
Great Britain, China, Japan, and Singapore. Our international sales will be
limited if we cannot establish relationships with international distributors,
establish additional foreign operations, expand international sales channel
management, hire additional personnel and develop relationships with
international service providers. Even if we are able to successfully continue
our international operations, we may not be able to maintain or increase
international market demand for our products. Our international operations are
subject to a number of risks, including:

         o        unexpected changes in regulatory requirements, tax rates or
                  tariffs that make our products and services more expensive and
                  therefore less attractive to present and potential customers;
         o        challenges in staffing and managing foreign operations due to
                  the limited number of qualified candidates, employment laws
                  and practices in foreign countries, any of which could
                  increase the cost and reduce the efficiency of operating in
                  foreign countries;

                                        9



         o        technology standards that differ from those on which our
                  products are based, which could require expensive redesign and
                  retention of personnel familiar with those standards;
         o        longer accounts receivable payment cycles and possible
                  difficulties in collecting payments which may increase our
                  operating costs and hurt our financial performance;
         o        political and economic instability; and
         o        certification requirements.

         Any of these factors could harm our international operations and
negatively affect our financial performance. The recurrence of weakness in these
economies or of weakness in other foreign economies could have a significant
negative effect on our future operating results.

WE RECENTLY IMPLEMENTED AN ENTERPRISE RESOURCE PLANNING (ERP) SYSTEM, AND IF
THIS INFORMATION TECHNOLOGY PROJECT PROVES TO BE UNWIELDY OR IF THE SOFTWARE
TOOL TURNS OUT TO BE INEFFECTIVE, IT COULD HAVE A MATERIAL ADVERSE EFFECT ON OUR
BUSINESS, RESULTS OF OPERATIONS AND FINANCIAL CONDITION.

         We implemented an ERP system in early December 2001 to help increase
the efficiency of our operations. This required a significant investment in
money, time and resources. More than 400 employees were trained on the software
tool and the smooth transition from one system to another has not yet been
accomplished. If this information technology project proves to be unwieldy or if
the software tool turns out to be ineffective, it could have a material adverse
effect on our business, results of operations and financial condition.

WE REQUIRE EMPLOYEES WHO ARE KNOWLEDGEABLE ABOUT THE SPECIALIZED NATURE OF OUR
BUSINESS. IF WE ARE UNABLE TO ATTRACT AND RETAIN SUFFICIENT NUMBERS OF HIGHLY
SKILLED TECHNICAL, SALES AND MARKETING AND OTHER PERSONNEL, OUR OPERATIONS AND
FINANCIAL RESULTS WOULD SUFFER.

         Due to the specialized nature of our business, we are highly dependent
on the continued service of and on the ability to attract and retain, qualified
engineering, sales, marketing and senior management personnel in the area of
fiber optics. The loss of key employees or management personnel could have a
material adverse effect on our business and operating results. We may not be
able to continue to attract and retain the qualified personnel necessary for the
development of our business.

         We must provide significant training for our employee base due to the
highly specialized nature of fiber-optic test, measurement and automation
equipment. Our current engineering personnel may be inadequate and we may fail
to assimilate and train new employees. Highly skilled employees with the
education and training that we require, especially employees with significant
experience and expertise in fiber optics, are in high demand. Once trained, our
employees may be hired by our competitors.

OUR BUSINESS STRATEGY AND OUR ABILITY TO MAINTAIN OUR COMPETITIVE POSITION
DEPEND ON THE CONTINUED SERVICES OF OUR SENIOR MANAGEMENT TEAM LED BY GERMAIN
LAMONDE, OUR CHAIRMAN OF THE BOARD, PRESIDENT AND CHIEF EXECUTIVE OFFICER. THE
LOSS OF ANY MEMBER OF THE SENIOR MANAGEMENT TEAM WOULD ADVERSELY AFFECT OUR
BUSINESS.

         Our ability to maintain our competitive position depends to a
significant extent on the efforts and abilities of our senior management,
particularly Germain Lamonde, our Chairman of the Board, President and Chief
Executive Officer. The managerial, technical and other services of our senior
management team would be difficult to replace and if we lose the services of one
or more of our executive officers, or if one of them decides to join a
competitor or otherwise compete directly or indirectly against us, our business
would be seriously harmed. The loss of their services would jeopardize our
ability to maintain our competitive position. We do not have "key person" life
insurance policies covering any of our employees.

                                       10



OUR INTELLECTUAL PROPERTY AND PROPRIETARY TECHNOLOGY ARE IMPORTANT TO THE
CONTINUED SUCCESS OF OUR BUSINESS. OUR FAILURE TO PROTECT THIS PROPRIETARY
TECHNOLOGY MAY SIGNIFICANTLY IMPAIR OUR COMPETITIVE POSITION.

         Our success and ability to compete depend to a significant extent on
our proprietary technology, since that is how we attempt to keep others from
using the innovations that are central to our existing and future products. We
currently hold 18 U.S. and 7 Canadian issued patents and have 16 U.S. and 15
Canadian patent applications pending, along with 4 patent applications pending
under the Patent Cooperation Treaty. We also rely on a combination of copyright
and trademark laws, trade secrets, confidentiality procedures, contractual
provisions and license agreements to protect our proprietary technology. We may
have to engage in litigation in order to protect our patents and other
intellectual property rights, or to determine the validity or scope of the
proprietary rights of others. This kind of litigation can be time-consuming and
expensive, regardless of whether we win or lose. Because it is critical to our
success that we are able to prevent competitors from copying our innovations, we
intend to continue to seek patent and trade secret protection for our
technologies. The process of seeking patent protection can be long and expensive
and we cannot be certain that any currently pending or future applications will
actually result in issued patents, or that, even if patents are issued, they
will be of sufficient scope or strength to provide meaningful protection or any
commercial advantage to us. Furthermore, others may develop technologies that
are similar or superior to our technology, or design around the patents that we
own. We also rely on trade secret protection for our technology, in part through
confidentiality agreements with our employees, consultants, distributors and
third parties. However, these agreements may be breached or otherwise not
effective and we may not have adequate remedies for any breach or shortfall of
these agreements. In any case, others may come to know about our trade secrets
through a variety of methods. In addition, the laws of some territories in which
we sell our products may not protect our intellectual property rights to the
same extent as do the laws of Canada and the United States.

         Despite our efforts, our intellectual property rights, particularly our
existing or future patents, may be invalidated, circumvented, challenged or
required to be licensed to others. Furthermore, others may develop technologies
that are similar or superior to our technology, duplicate or reverse engineer
our technology, or design around the patents owned or licensed by us. We cannot
be sure that the steps that we take to protect our technology will prevent
misappropriation or infringement. If we fail to protect our technology so that
others may copy or use it, we will be less able to differentiate our products
and our sales will decline.

IF OTHERS CLAIM THAT OUR PRODUCTS INFRINGE UPON THEIR INTELLECTUAL PROPERTY
RIGHTS, WE MAY BE FORCED TO SEEK EXPENSIVE LICENSES, RE-ENGINEER OUR PRODUCTS,
ENGAGE IN EXPENSIVE AND TIME-CONSUMING LITIGATION OR STOP MARKETING THE
CHALLENGED PRODUCTS, WHICH COULD ADVERSELY AFFECT OUR ABILITY TO SELL OUR
PRODUCTS AND COULD INCREASE OUR COSTS.

         Litigation regarding intellectual property rights is common in the
technology industry and, for this reason, we expect that third-party
infringement claims involving technologies may increase. If an infringement
claim is filed against us, we may be prevented from using some of our
technologies and may incur significant costs to resolve the claim.

         We could incur substantial costs in defending ourselves and our
customers against infringement claims. Litigation could also adversely affect
sales of the challenged product or technology and divert the efforts of our
management and technical personnel. In the event of a claim of infringement, we
may be required to obtain one or more licenses from third parties. We cannot
assure you that we, or our customers, could obtain necessary licenses from third
parties at a reasonable cost or at all. If we fail to

                                       11



obtain a license where one is required, we could incur substantial liabilities
and be forced to suspend the marketing of the challenged products.

OUR INSURANCE MAY NOT BE SUFFICIENT TO COVER ALL POTENTIAL LIABILITY. A
SUCCESSFUL CLAIM EXCEEDING OUR POLICY LIMITS WILL REDUCE OUR WORKING CAPITAL,
INCREASE OUR EXPENSES AND HAVE A NEGATIVE EFFECT ON OUR OPERATING RESULTS.

         Our products are designed to help telecommunications carriers and
manufacturers of optical components, value-added optical modules and optical
networking systems ensure network reliability. The failure of our products to
perform to client expectations could give rise to product liability and warranty
claims. We carry insurance for product liability and take accounting reserves
for warranty claims that we consider adequate in view of industry practice. In
addition, we may face other types of claims by third parties in relation to the
conduct of our business and a successful claim against us for an amount
exceeding our policy limits would force us to use our own resources to pay the
claim, which could result in a reduction of our working capital available for
other uses, increase our expenses and have a negative effect on our financial
condition and results of operations.

WE MAY BECOME INVOLVED IN COSTLY AND TIME-CONSUMING LITIGATION THAT MAY
SUBSTANTIALLY INCREASE OUR COSTS AND HARM OUR BUSINESS.

         We may from time to time become involved in various lawsuits and legal
proceedings. For example, EXFO is a defendant in a putative securities class
action filed in the United States District Court for the Southern District of
New York. In addition, we have instituted a claim against a former employee of
one of our subsidiaries, in relation to a breach of contractual confidentiality
obligations. Litigation is subject to inherent uncertainties, and an adverse
result in these or other matters that may arise from time to time could have a
material adverse effect on our business, results of operations or financial
condition.

         Any litigation to which we are subject could require significant
involvement of our senior management and may divert management attention from
our business and operations. For more information about current legal
proceedings, see "Item 4.B. - Legal Proceedings" in our Annual Report on Form
20-F.

FLUCTUATIONS IN THE EXCHANGE RATES BETWEEN THE CANADIAN DOLLAR AND THE US DOLLAR
AND OTHER CURRENCIES MAY ADVERSELY AFFECT OUR OPERATING MARGINS.

         The majority of our sales is denominated in US dollars. However, a
large portion of our operating expenses and capital expenditures are denominated
in Canadian dollars. As a result, we are exposed to fluctuations in the exchange
rates between the Canadian dollar and the US dollar and other currencies. An
increase in the value of the Canadian dollar relative to the US dollar could
have a material adverse effect on our operating margins.

UNEXPECTED DECLINES IN OUR RESEARCH AND DEVELOPMENT TAX CREDITS AND GRANTS MAY
HAVE AN ADVERSE EFFECT ON OUR BUSINESS.

         Our historical operating results reflect substantial benefits from
programs sponsored by federal, provincial and state governments for the support
of research and development. Research and development tax credits and grants
represented 22.7 % of our gross research and development expenses for the year
ended August 31, 2001 and 23.2 % for the fifteen months ended November 30, 2001.

         If unexpected changes in the laws or government policies terminate or
adversely modify the Canadian and Quebec government programs, under which we
receive the major part of our research and

                                       12



development tax credits and grants, or if we unexpectedly become unable to
participate in or take advantage of these programs, then our net research and
development expenses will materially increase. To the extent that we increase
our research and development activities outside Canada or Quebec, which could
result from, among other things, future acquisitions, the increased activities
may not be eligible for these programs. If we are required to decrease our
research and development activities, we may be unable to compete effectively.

WE MAY NEED ADDITIONAL CAPITAL, AND MAY NOT BE ABLE TO RAISE ADDITIONAL CAPITAL
ON FAVORABLE TERMS OR AT ALL, WHICH COULD LIMIT OUR ABILITY TO GROW AND COULD
INCREASE OUR COSTS.

         Our future liquidity and capital requirements are difficult to predict
because they depend on numerous factors, including the success of our existing
and new product offerings as well as competing technological and market
developments. As a result, we may not be able to generate sufficient cash from
our operations to meet additional working capital requirements, support
additional capital expenditures or take advantage of acquisition opportunities.
Accordingly, we may need to raise additional capital in the future.

         Our ability to obtain additional financing will be subject to a number
of factors, including market conditions and our operating performance. These
factors may render the timing, amount, terms and conditions of additional
financing unattractive for us. If we raise additional funds by selling equity
securities, the relative ownership of our existing investors could be diluted or
the new investors could obtain terms more favorable than previous investors. If
we raise additional funds through debt financing, we could incur significant
borrowing costs. If we are unable to raise additional funds when needed, our
ability to operate and grow our business could be impeded.

                                      EXFO

         We are a leading designer, manufacturer and marketer of fiber-optic
test, measurement, monitoring and automation solutions for the global
telecommunications industry. We believe that we offer the most extensive range
of products in the fiber-optic test, measurement, monitoring and automation
industry. Fiber-optic test, measurement, monitoring and automation equipment is
mainly used by telecommunications carriers, optical component and system
manufacturers, as well as research and development laboratories to meet their
physical, optical and protocol testing requirements.

         We were founded in 1985 in Quebec City. We have grown from a
two-employee supplier of portable handheld test instruments to a leading
designer, manufacturer and marketer of an extensive line of fiber-optic test,
measurement, monitoring and automation equipment. As of December 31, 2001, we
had a workforce of 1,099 employees and our products are distributed in over 70
countries.

         We, along with our wholly owned subsidiaries, develop products mainly
for two markets. Our Portable and Monitoring Division provides handheld and
modular instruments primarily to telecommunications carriers and network service
providers. Our Industrial and Scientific Division and our subsidiaries, Burleigh
and EXFO Photonic, design an extensive line of high-performance instruments and
automated manufacturing equipment for optical component and system manufacturers
as well as for research and development labs. EXFO Protocol contributes to both
of our product divisions.

         We have received more than 45 industry and commerce awards. In 2001, we
were named one of the top 100 employers in Canada by McLean's, a national
current affairs magazine. In 2000, we were named winner of the Outstanding
Corporate Innovator Award by the U.S.-based Product Development and Management
Association (PDMA). Prior to becoming a public company in June 2000, we were
recognized as one of the 50 Best-Managed Private Companies in Canada by Arthur
Andersen Consulting and the Financial Post for five consecutive years.

ANNOUNCEMENT OF FIRST QUARTER RESULTS

         In January 16, 2002, we announced our financial results for the first
quarter ended November 30, 2001. We reported sales of $20.1 million for the
quarter ended November 30, 2001 compared to $28.5 million for the same period in
fiscal 2001. Our net loss for the first quarter of 2002 was $19.1 million, or
$0.33 per share, compared to net earnings of $7.5 million, or $0.16 per share,
for the same period last year. Gross margin, including an inventory write-off of
$3.5 million, amounted to 37.8% of sales for the first quarter of 2002 compared
to 63.9% of sales for the same period in 2001. Excluding this non-recurring
charge, gross margin would have reached 55.1%, in line with our expectations
based on actual sales for this quarter. Altogether, we incurred restructuring
charges of $3.9 million in the first quarter of fiscal 2002. The financial
results of our newly acquired EXFO Protocol were reflected in our financial
results for the first quarter as the acquisition closed on November 2, 2001.

FURTHER ACTIONS

         To align costs with current market conditions, in December 2001, we
implemented additional measures that will provide approximately $6 million in
annualized pre-tax savings. Among other things:

         o        we lowered our operating expenses;
         o        we froze employee salaries; and
         o        we reduced our workforce by 10%.

         We incurred a one-time charge relating to this plan of approximately
$3.9 million in the quarter ended November 30, 2001.

RECENT ACQUISITION

         EXFO PROTOCOL INC. (FORMERLY AVANTAS NETWORKS CORPORATION)

         In November 2001, we acquired all of the shares issued and outstanding
of Avantas Networks Corporation and simultaneously changed the name of that
company to EXFO Protocol. The total consideration paid amounted to $94,952,000,
or $69,381,000 net of $25,571,000 of cash and cash equivalents acquired. The
consideration paid consisted of $9,756,000 in cash, net of cash and cash
equivalents acquired of $25,571,000 and the issuance of 4,374,573 of our
subordinate voting shares. EXFO Protocol, a company based in Montreal, Canada,
operating since 1998 and having 116 employees as of December 31, 2001, is a
supplier of fiber-optic testing and optical network performance management
equipment that supports a wide range of protocols and data transmission rates.
This latest acquisition will enable us to enter the critical protocol-layer
testing market. EXFO's products test the highway, or the fiber, optical
components and value-added optical modules that make up the physical layer of an
optical network. EXFO's products also cover the numerous lanes along the
highway, or the DWDM wavelengths carrying bandwidth within the optical layer of
a network. Using EXFO Protocol's products, our products will also test the
traffic, or the bits and bytes running through the protocol layer of a network.

                                       15

                              PLAN OF DISTRIBUTION

         The selling shareholders will act independently of us in making
decisions with respect to the timing, manner and size of each sale.

         The selling shareholders may sell their subordinate voting shares
covered by this prospectus from time to time in transactions, including block
transactions, on the Nasdaq National Market, The Toronto Stock Exchange or any
other securities exchange or automated interdealer quotation system on which our
subordinate voting shares are listed or quoted, in negotiated transactions,
through a combination of such methods of sale or otherwise, including private
sales, at fixed prices that may be changed, at market prices prevailing at the
time of sale at prices related to those prevailing market prices, at varying
prices determined at the time of sale or at negotiated prices. The selling
shareholders may effect those transactions by selling their subordinate voting
shares directly to purchasers, through broker-dealers acting as agents of the
selling shareholders, or to broker-dealers acting as agents for selling
shareholders, or to broker-dealers acting as principals and thereafter sell the
shares from time to time in transactions, including block transactions, on the
Nasdaq National Market and The Toronto Stock Exchange, in negotiated
transactions, through a combination of such methods of sale or otherwise. In
effecting sales, broker-dealers engaged by the selling shareholders may arrange
for other broker-dealers to participate. Such broker-dealers, if any, may
receive compensation in the form of discounts, concessions or commissions from
the selling shareholders and/or the purchasers of the shares for whom such
broker-dealers may act as agents or to whom they may sell as principals, or
both, which compensation as to particular broker-dealer might be in excess of
customary commissions.

         In connection with distributions of shares or otherwise, the selling
shareholders may enter into hedging transactions with broker-dealers. In those
transactions, broker-dealers may engage in short sales of our subordinate voting
shares in the course of hedging the positions they assume with the selling
shareholders. The selling shareholders also may sell our subordinate voting
shares short and redeliver shares to close out those short positions. The
selling shareholders may enter into option, forward or other transactions with
broker-dealers which require the delivery of subordinate voting shares to the
broker-dealer. The broker-dealer may then resell or otherwise transfer those
subordinate voting shares under this prospectus. The selling shareholders may
also loan or pledge shares to the broker-dealer. The broker-dealer may sell the
shares so loaned, or upon default the broker-dealer may sell the shares so
pledged, under this prospectus.

         The selling shareholders and any broker-dealers or agents that
participate with the selling shareholders in the distribution of the subordinate
voting shares may be deemed to be "underwriters" within the meaning of Section
2(11) of the U.S. Securities Act of 1933. Any commissions paid or any discounts
or concessions allowed to any such persons, and any profits received on the
resale of the subordinate voting shares purchased by them may be deemed to be
underwriting commission or discounts under the U.S. Securities Act of 1933.

         We have agreed to bear all expenses of registration of the shares other
than legal fees and expenses, if any, of counsel or other advisors of the
selling shareholders. The selling shareholders will bear any commissions,
discounts, concessions or other fees, if any, payable to broker-dealers in
connection with any sale of their subordinate voting shares.

         Because each of the selling shareholders may be deemed to be an
"underwriter" within the meaning of Section 2(11) of the U.S. Securities Act of
1933, the selling shareholders will be subject to the prospectus delivery
requirements of the U.S. Securities Act of 1933. We have informed the selling
shareholders that the anti-manipulative provisions of Regulation M under the
U.S. Securities Exchange Act of 1934 may apply to their sales in the market.

                                       18



         In addition to sales of our subordinate voting shares under the
registration statement of which this prospectus is a part, the selling
shareholders may sell their subordinate voting shares in compliance with Rule
144 under the U.S. Securities Act of 1933.


                                  LEGAL MATTERS

         The validity of the subordinate voting shares will be passed upon for
us by Fasken Martineau DuMoulin LLP, Montreal, Canada. Paul, Weiss, Rifkind,
Wharton & Garrison, New York, New York has acted as U.S. counsel for us in
connection with the filing of the registration statement of which this
prospectus forms a part.
