PROSPECTUS SUMMARY

You should read the entire prospectus carefully, including our consolidated financial statements and the related notes included elsewhere in this prospectus.

EXFO

We are a leading designer, manufacturer and marketer of fiber-optic test, measurement and monitoring instruments for the telecommunications industry. We believe that we are the largest manufacturer of test, measurement and monitoring instruments that is exclusively dedicated to fiber optics. Unlike traditional electrical transmission systems, which transmit electrical signals along copper wires, fiber-optic transmission systems use pulses of light along glass or plastic fiber, often referred to as optical fiber. When light travels along optical fiber and through the optical equipment that link optical fibers together, it is subject to unwanted effects such as reflection, attenuation, noise and various types of dispersion, all of which degrade signal quality and reduce transmission performance. Fiber-optic test, measurement and monitoring equipment is critical for measuring these effects and for helping communications carriers and manufacturers ensure network performance and reliability.

Demand for fiber-optic test, measurement and monitoring equipment has been driven by increased production and deployment of optical fiber and related equipment in order to meet the growing demand for telecommunications capacity. Ryan, Hankin & Kent, a leading telecom market research firm, forecasts that Internet traffic will increase from 350,000 terabytes, or trillions of bytes, per month at the end of 1999 to more than 15 million terabytes per month in 2003, representing a compound annual average growth rate of 156%.

Our customers use fiber-optic test, measurement and monitoring equipment mainly to:

- ensure the quality of networks as they are being deployed;

- diagnose and repair problems within an optical network;

- monitor the quality of an optical signal as it passes through a network;

- analyze fiber-optic components and equipment during production and assembly as well as quality control and conformity testing; and

- conduct sophisticated tests during the research and development of fiber-optic products.

We believe that we have positioned ourselves as the supplier offering the most extensive range of products in the fiber-optic test, measurement and monitoring industry. Our success has been largely based on our exclusive focus on fiber-optic test, measurement and monitoring instruments. We have developed optical technologies and advanced testing algorithms that we leverage across our various product lines. Our success is primarily due to:

- our development of a range of products based on a modular system design consisting of Windows-based platforms that can accommodate several data acquisition test modules;

- our high degree of technological innovation, as illustrated by our leading position in our industry in the development and commercialization of a number of new fiber-optic test and measurement products;

- the high quality of our products as a result of our comprehensive quality assurance program, which has been certified ISO 9001 since 1994, and our compliance with demanding industry standards; and

- our highly qualified and specialized internal customer support teams that offer pre-sales evaluation, installation, channel and customer training and post-sales support.

1

We develop products principally for two markets. Our Portable and Monitoring Division provides solutions primarily to telecommunications carriers, cable television companies, public utilities, private network operators, as well as third-party installers and equipment rental companies. Our Scientific Division, established in 1996, designs an extensive line of more sophisticated and higher performance instruments for manufacturers of optical fiber, optical components, value-added optical modules and optical networking systems. Our Scientific Division also designs products for research and development markets.

We intend to expand our leadership position in the fiber-optic test, measurement and monitoring industry and to increase our market share through the following initiatives:

- expand our technological leadership;

- invest in strategic sectors;

- leverage our modular design across our product lines;

- expand our sales and marketing efforts;

- reduce our delivery lead times; and

- pursue complementary acquisitions.

Our head office is located at 465 Godin Avenue, Vanier, Quebec, Canada, G1M 3G7 and our telephone number is (418) 683-0211. Our e-mail address is info@exfo.com and our Web site is www.exfo.com.

RISK FACTORS

Investing in our subordinate voting shares involves a high degree of risk. You should carefully consider the risks described below as well as all the other information in this prospectus, including our financial statements and related notes, before investing in our subordinate voting shares. Our business, operating results and financial condition could be seriously harmed due to any of the following risks. The trading price of our subordinate voting shares could decline due to any of these risks and you could lose all or part of your investment.

RISKS RELATED TO OUR INDUSTRY AND BUSINESS

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 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 MUST CONTINUE TO OVERCOME SIGNIFICANT AND INCREASING COMPETITION IN OUR INDUSTRY IN ORDER TO CONTINUE OUR GROWTH AND PRODUCTIVITY.

The market for fiber-optic test, measurement and monitoring 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 many new competitors to emerge as the market for fiber-optic test, measurement and monitoring equipment expands and evolves in response to technical innovations.

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 Agilent Technologies Inc. and Wavetek Wandel & Golterman, have longer operating histories and significantly greater financial, technical and marketing resources. Consequently, these competitors are able to devote greater resources to the development, marketing, sale and support of their products. They are also better positioned than we are to acquire companies and new technologies that may displace our products or make them obsolete.

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 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 INTELLECTUAL PROPERTY AND PROPRIETARY TECHNOLOGY, WHICH INCLUDES NINE PATENTS AND FOURTEEN PATENT APPLICATIONS, 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 four U.S. and two Canadian issued patents, three foreign issued patents and have six U.S. and eight Canadian patent applications pending. In addition, we 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

6

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, our foreign issued patents only cover France, Germany and Japan, and 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 obtain a license where one is required, we could incur substantial liabilities and be forced to suspend the marketing of the challenged products.

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 competition for such personnel is intense. 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. In addition, if we are unable to hire additional qualified personnel as needed, we may not be able to adequately manage and complete our existing sales commitments and to bid for and execute additional sales.

We must provide significant training for our growing employee base due to the highly specialized nature of fiber-optic test, measurement and monitoring 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.

7

OUR BUSINESS STRATEGY AND OUR ABILITY TO OPERATE PROFITABLY DEPEND ON THE CONTINUED SERVICES OF OUR SENIOR MANAGEMENT TEAM LED BY GERMAIN LAMONDE, OUR CHAIRMAN OF THE BOARD, PRESIDENT AND CHIEF EXECUTIVE OFFICER, OR ANY OF OUR SENIOR MANAGEMENT, THE LOSS OF WHOM 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. Although we expect to enter into an employment agreement with Mr. Lamonde prior to the closing of the offering, we do not have employment agreements with any of our other key executives. Their managerial, technical and other services 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.

IF WE ARE NOT ABLE TO MANAGE OUR GROWTH EFFECTIVELY, WE MAY NOT BE ABLE TO MAINTAIN OR IMPROVE OUR CURRENT LEVEL OF PROFITABILITY.

We expect our business and the industry in which we compete to continue to undergo rapid change. We plan to significantly expand our distribution and marketing capabilities by opening additional international sales offices and service centers, by bolstering our key account management program, by hiring application engineers and by increasing our sales network worldwide. We also intend to increase our manufacturing floor space by 167% through the planned acquisition of an additional facility of approximately 112,000 square feet. Finally, we have had a significant increase in our number of employees from 429 on May 31, 1999 to 671 on May 31, 2000. Our ability to be profitable depends on our ability to manage this rapid growth. The failure of our management to respond effectively to and manage changing technological and business conditions could have a material adverse impact on our business, financial condition and results of operations.

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 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. 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 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.

Our industry is very competitive and prices for fiber-optic test, measurement and monitoring equipment will likely decline. These price declines result from factors such as:

- increased competition for business;

- a limited number of potential customers;

- competition from companies with lower labor and production costs;

- introduction of new products by competitors; and

- greater economies of scale for higher-volume manufacturers.

8

We may have to increase our manufacturing capacity and our unit volume sold in order to maintain our existing sales. If we add capacity, our fixed costs will increase. As a result, we would have to increase the level of sales to maintain operating margins. If we are unable to continuously reduce our manufacturing costs or introduce new products with higher margins, our gross margins could decline.

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, 1999, customers outside of the United States and Canada accounted for 44% of our sales and for the six months ended February 29, 2000, these customers accounted for 36% of our sales. We plan to increase our international sales activities and have recently opened offices in 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:

- unexpected changes in regulatory requirements, tax rates or tariffs that make our products and services more expensive and therefore less attractive to potential customers;

- 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;

- 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;

- longer accounts receivable payment cycles and possible difficulties in collecting payments which may increase our operating costs and hurt our financial performance;

- political and economic instability; and

- certification requirements.

Any of these factors could harm our international operations and negatively affect our financial performance. For example, we currently face problems with increasing, and constantly changing, certification requirements. In addition, although the amounts involved were not material, we have in the past encountered difficulties collecting accounts receivable in countries experiencing economic instability. 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.

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:

- loss of customers;

- damage to our brand reputation;

- failure to attract new customers or achieve market acceptance;

- diversion of development and engineering resources;

- legal actions by our customers, including claims for consequential damages and loss of profits; and

9

- 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.

OUR INSURANCE MAY NOT BE SUFFICIENT TO COVER ALL POTENTIAL PRODUCT LIABILITY AND WARRANTY CLAIMS. A SUCCESSFUL CLAIM EXCEEDING OUR POLICY LIMIT 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 product liability insurance that we consider adequate in view of industry practice. However, a successful claim against us for an amount exceeding our policy limit 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 results of operations.

AS OUR COMPETITORS CONSOLIDATE, THEY MAY OFFER PRODUCTS OR PRICING THAT WE CANNOT MEET, WHICH COULD CAUSE OUR SALES TO DECLINE.

Consolidation in the fiber-optic test, measurement and monitoring industry could intensify the competitive pressures that we face. Recently, some of our competitors have merged or have been acquired by larger companies. These combined companies could produce more high-performance products and offer them at more competitive prices.

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 revenues, and cause quarterly fluctuations in our operating results include:

- the length of our product sales cycle, especially for our higher priced and more complex products;

- our ability to sustain product volumes and high levels of quality across all product lines; and

- the timing of introduction and market acceptance of new products by us, our competitors or our suppliers.

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

- 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; and

- difficulties in collecting accounts receivable.

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.

10

IF OPTICAL FIBER IS REPLACED BY ANOTHER MEDIUM AS THE PRIMARY SOLUTION FOR BANDWIDTH-INTENSIVE APPLICATIONS, OR IF HIGH-BANDWIDTH TRANSMISSION NETWORKS ARE NO LONGER IN GREAT DEMAND, WE COULD EXPERIENCE A SIGNIFICANT LOSS OF SALES.

The increase in fiber-optic cable production and the growth in fiber deployment are causing increased demand for fiber-optic test, measurement and monitoring equipment. If the demand for these markets decreases or disappears, or if optical fiber is replaced by a higher-performance medium, it could have a material adverse effect on our business, financial condition and results of operations.

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 OR EXPERIENCE MANUFACTURING DELAYS.

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. 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 are 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. In the case of some parts in short supply, suppliers have imposed strict allocations that limit the number of these parts that they will supply to a given customer in a specified time period. Although to date suppliers have not made selective allocations that adversely affected us, these suppliers may choose, in the future, to increase allocations to larger, more established companies, which could reduce our allocations and harm our ability to manufacture our products.

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:

- customer dissatisfaction;

- cancellation of orders;

- negative publicity;

- loss of sales;

- slower market acceptance of our products; and

- 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.

FLUCTUATIONS IN THE EXCHANGE RATES BETWEEN THE CANADIAN DOLLAR AND THE U.S. DOLLAR MAY ADVERSELY AFFECT OUR OPERATING MARGINS.

The majority of our sales is denominated in U.S. dollars. However, a majority 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 U.S. dollar. An increase in the value of the Canadian dollar relative to the U.S. dollar could have a material adverse effect on our operating margins.

AS OUR CUSTOMERS CONSOLIDATE, THEY MAY REDUCE 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 recently merged. Although to date we have not experienced

11

any adverse effects as a result of these mergers, these merged customers could, in the future, obtain products from a source other than us, which would cause our sales to decline. In addition, some of our manufacturer customers may merge with or acquire our competitors and, as a result, discontinue their relationships with us.

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.

WE MAY NOT BE ABLE TO SUSTAIN OUR RESEARCH AND DEVELOPMENT ACTIVITIES AS OUR RESEARCH AND DEVELOPMENT CREDITS AND GRANTS DECLINE BECAUSE OF THE INCREASING EFFECTIVE COST OF OUR RESEARCH AND DEVELOPMENT ACTIVITIES.

Our historical operating results reflect substantial benefits from programs sponsored by the Canadian and Quebec governments for the support of research and development. Research and development tax credits and grants represented 32.5% of our gross research and development expenses for the year ended August 31, 1999 and 31.4% for the six months ended February 29, 2000. These tax credits and grants will decline as our assets grow. Accordingly, the effective cost of our future research and development activities will increase.

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

If unexpected changes in the laws or government policies terminate or adversely modify the government programs, under which we receive research and 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 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 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.

Although we have no existing commitments or agreements regarding any acquisitions, 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.

We have in the past made strategic acquisitions of intellectual property, such as the arrangements we have with GAP Optique S.A. and of complementary products through the recent acquisition of Nortech Fibronic Inc. 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:

- issue shares that would dilute your percentage ownership;

- incur debt;

- assume liabilities; or

- incur expenses related to in-process research and development, amortization of goodwill and other intangible assets.

These acquisitions also involve numerous risks, including:

- problems combining the acquired operations, technologies or products;

- unanticipated costs or liabilities;

12

- diversion of management's attention from our core business;

- adverse effects on existing business relationships with suppliers and customers;

- risks associated with entering markets in which we have no or limited prior experience; and

- potential loss of key employees, particularly those of acquired organizations.

We cannot assure you that we will be able to successfully integrate any businesses, products, technologies or personnel that we might acquire in the future, which may harm our business.

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 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.

OUR PRODUCTS MAY BE REQUIRED TO CONFORM TO NEW AND UNFORESEEN REGULATORY REQUIREMENTS WHICH 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.

RESIDUAL YEAR 2000 ISSUES MAY DISRUPT OUR OPERATIONS, SUBJECT US TO LIABILITIES AND COSTS AND AFFECT THE TIMING OF OUR SALES.

Since many of our test systems rely on software, they could be affected by Year 2000 issues. To date, we have not identified any specific Year 2000 problems adversely affecting our business. However, we may still be vulnerable to any residual Year 2000 problems causing the failure of any of our products, as a result of which we could lose customers, suffer significant disruptions in our business, lose sales and incur substantial liabilities and expenses. We could also become involved in costly litigation resulting from Year 2000 problems. This could seriously harm our business, financial condition and results of operations.

RISKS RELATED TO THIS OFFERING AND OWNING OUR SUBORDINATE VOTING SHARES

OUR PRINCIPAL SHAREHOLDER OWNS ALL OF OUR MULTIPLE VOTING SHARES AND WILL BE ABLE TO EXERCISE SIGNIFICANT INFLUENCE OVER OUR AFFAIRS. HOLDERS OF SUBORDINATE VOTING SHARES WILL HAVE A LIMITED ROLE IN OUR AFFAIRS.

Holders of our subordinate voting shares are entitled to one vote per share and holders of our multiple voting shares are entitled to ten votes per share. Following the closing of this offering, Germain Lamonde, our Chairman of the Board, President and Chief Executive Officer, will have control over all of our outstanding multiple voting shares representing 98.3% of the outstanding voting power. As a result, he will be able to control all matters requiring approval by our shareholders, including the election of directors and the approval of mergers or other business combinations. The concentration of ownership would make it more difficult for a third party to acquire our control if Germain Lamonde were to oppose the change of control transaction. This could prevent our shareholders from realizing a premium over the market prices for their subordinate voting shares or from bringing about a change in management.

WE WILL HAVE BROAD DISCRETION REGARDING THE USE OF PROCEEDS FROM THIS OFFERING. IF WE DO NOT USE THE PROCEEDS EFFECTIVELY TO DEVELOP AND GROW OUR BUSINESS, YOUR INVESTMENT COULD SUFFER.

We intend to use approximately $17.3 million to repay promissory notes to be issued to satisfy the dividends to be declared to our existing shareholders prior to the closing of this offering and approximately $10.0 million to repay indebtedness. While we do not have specific uses for a significant portion of the balance of the proceeds from this offering, we expect it will give us the opportunity to compete more effectively against our competitors, many of which are larger than we are and have significantly greater financial resources. Although to date we have not identified any specific opportunity nor budgeted for any specific projects, we may use the balance of the proceeds to acquire or invest in related businesses, products and technologies. As a result, our management will have broad discretion in how we use the net proceeds from this offering. You will not have the opportunity to evaluate the economic, financial or other information on which we base our decisions regarding the use of the net proceeds from this offering and we may spend these proceeds in ways that do not increase our operating results or market value.

TECHNOLOGY-RELATED STOCK PRICES ARE ESPECIALLY VOLATILE. THIS VOLATILITY MAY DEPRESS OUR SHARE PRICE AND YOU MAY NOT BE ABLE TO RESELL YOUR SHARES AT A PRICE AT OR ABOVE THE INITIAL PUBLIC OFFERING PRICE.

Stock market prices for technology companies have been volatile and the market price of our subordinate voting shares may be volatile. In particular, the market prices of the shares of many companies in the technology sector have experienced wide fluctuations that have often been unrelated to their operating performance. As a result, you may not be able to resell your subordinate voting shares at or above the initial public offering price. Although the market price of our subordinate voting shares will in part be based on our operating and financial performance, it may also be based on conditions in the fiber-optic industry and other factors beyond our control.

MORE THAN 38 MILLION SHARES, IN ADDITION TO THE SHARES COVERED BY THIS PROSPECTUS, WILL BE OUTSTANDING AFTER THIS OFFERING AND SALES OF THESE SHARES MAY DEPRESS OUR SHARE PRICE.

After this offering, we will have 44,709,605 shares outstanding. Sales of a substantial number of our subordinate voting shares in the public market following this offering could cause the market price of our subordinate voting shares to drop. All of the subordinate voting shares sold in this offering will be freely tradeable. Subordinate voting shares issuable upon conversion of 38,000,000 multiple voting shares, held by Germain Lamonde, will be available for sale in the public market 180 days after the date of this prospectus, subject to resale restrictions under applicable Canadian and U.S. securities laws. See "Shares Eligible for Future Sale."

THERE MAY BE NO ACTIVE TRADING MARKET IN OUR SUBORDINATE VOTING SHARES AFTER THIS OFFERING, WHICH MAY MAKE IT DIFFICULT FOR YOU TO RESELL YOUR SHARES.

Prior to this offering, there was no organized market on which to trade the subordinate voting shares and there can be no assurance that an active market for the trading of the shares will develop or be maintained after

14

this offering. Factors such as our financial results and the financial results of our competitors, general industry conditions and financial markets could result in fluctuations in the share price of the subordinate voting shares.

YOU WILL SUFFER AN IMMEDIATE DILUTION OF YOUR INVESTMENT.

After giving effect to this offering, the offering price of each subordinate voting share will exceed the net tangible book value per share by $18.42, representing a dilution factor of 87.7%. Accordingly, investors who purchase subordinate voting shares pursuant to this offering will be subject to an immediate dilution in the book value of their investments. See "Dilution."

WE ARE NOT LIKELY TO PAY DIVIDENDS FOR THE FORESEEABLE FUTURE.

Except for the dividend payable prior to the closing of this offering, we do not plan to pay dividends on our subordinate voting shares for at least the next three years. We currently intend to retain any earnings for reinvestment in our business. See "Dividend Policy."

SINCE WE ARE A CANADIAN COMPANY AND MOST OF OUR ASSETS AND KEY PERSONNEL ARE LOCATED IN CANADA, YOU MAY NOT BE ABLE TO ENFORCE ANY U.S. JUDGMENT FOR CLAIMS

YOU MAY BRING AGAINST US, OUR ASSETS, OUR KEY PERSONNEL OR THE EXPERTS NAMED IN THIS PROSPECTUS.

We have been organized under the laws of Canada. Many of our assets are located outside the United States. In addition, a majority of the members of our board of directors and our officers and the experts named in this prospectus are residents of countries other than the United States. As a result, it may be impossible for you to effect service of process within the United States upon us or these persons or to enforce against us or these persons any judgments in civil and commercial matters, including judgments under United States federal securities laws. In addition, a Canadian court may not permit you to bring an original action in Canada or to enforce in Canada a judgment of a U.S. court based upon civil liability provisions of U.S. federal securities laws. See "Enforceability of Civil Liabilities."

OUR BOARD OF DIRECTORS MAY ISSUE, WITHOUT SHAREHOLDERS' APPROVAL, AN UNLIMITED NUMBER OF PREFERRED SHARES THAT HAVE RIGHTS AND PREFERENCES SUPERIOR TO THOSE OF OUR SUBORDINATE VOTING SHARES. SUCH ISSUANCE MAY DELAY OR PREVENT A CHANGE OF CONTROL.

Our articles of incorporation allow the issuance of an unlimited number of preferred shares in one or more series. After this offering, there will only be one series of non-voting preferred shares outstanding. However, our board of directors may set the rights and preferences of any series of preferred shares in its sole discretion without the shareholders' approval. The rights and preferences of those preferred shares may be superior to those of the subordinate voting shares. Accordingly, the issuance of preferred shares may adversely affect the rights of holders of subordinate voting shares and could have the effect of delaying or preventing a change of control. See "Description of Share Capital."

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus contains forward-looking statements that involve risks and uncertainties. These statements relate to our future plans, objectives, expectations and intentions. We have identified these statements by the use of words such as "may", "will", "expect", "anticipate", "intend", "plan", "estimate", "believe", "continue" or other similar expressions. These forward-looking statements reflect our current expectations and assumptions as to future events that may not prove to be accurate. Our actual results are subject to a number of risks and uncertainties and could differ materially from those discussed in these statements. Factors that could contribute to these differences include, but are not limited to, those discussed in the section entitled "Risk Factors" and elsewhere in this prospectus. In light of the many risks and uncertainties surrounding our business and operations, you should keep in mind that we cannot guarantee that the forward-looking statements described in this prospectus will transpire. We undertake no obligation and do not intend, to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, except as may be required under applicable law.

ENFORCEABILITY OF CIVIL LIABILITIES

We have been organized under the laws of Canada and our executive offices are located in Quebec, Canada. Many of our directors, controlling persons and officers and representatives of the experts named in this prospectus, are residents of Canada and a substantial portion of their assets and a majority of our assets are located outside the United States. As a result, it may be difficult for you to effect service of process within the United States upon the directors, controlling persons, officers and representatives of experts who are not residents of the United States or to enforce against them judgments obtained in the courts of the United States based upon the civil liability provisions of the federal securities laws or other laws of the United States. There is doubt as to the enforceability in Canada against us or against any of our directors, controlling persons, officers or experts who are not residents of the United States, in original actions or in actions for enforcement of judgments of United States courts, of liabilities based solely upon the civil liability provisions of the U.S. federal securities laws. Therefore, it may not be possible to enforce those actions against us, our directors and officers or the experts named in this prospectus.

USE OF PROCEEDS

We expect to receive approximately $116,180,000 in net proceeds from the sale of 6,000,000 subordinate voting shares in this offering, assuming an initial public offering price of $21.00 per share, after deducting underwriting commissions and our estimated expenses in connection with this offering. We estimate that the net proceeds will be approximately $133,757,000 if the underwriters' over-allotment option is exercised in full.

Of the net proceeds that we will receive from this offering, we will use:

- approximately $17.3 million to repay promissory notes to be issued as payment for dividends that we plan to declare prior to the closing of this offering on the Class "A" shares held by GEXFO Investissements Technologiques inc., a company controlled by Germain Lamonde, Fiducie Germain Lamonde, a family trust for the benefit of Germain Lamonde and members of his family and G. Lamonde Investissements Financiers inc., a company controlled by Germain Lamonde. The debt evidenced by the promissory notes will bear no interest and will be payable on demand;

- approximately $2.0 million to repay our bank operating loan of C$3.0 million. The loan bears interest at the prime rate of the bank plus 1/2% and is payable on demand. As of June 7, 2000, the interest rate of this loan was 8.0%. We used the proceeds from that loan to pay the cash consideration and related expenses relating to our acquisition of Nortech Fibronic Inc. in February 2000;

- approximately $1.4 million to repay a C$2.0 million loan from 9080-9823 Quebec inc., a company controlled by Germain Lamonde. That loan bears interest at a rate equal to the prime rate plus 1% and is payable on demand. As of June 7, 2000, the interest rate of this loan was 8.5%;

- approximately $3.4 million to repay a C$5.0 million bank loan that has been made available to us in connection with our planned acquisition of real property in June 2000. The loan will bear interest at a rate equal to the prime rate plus 1/2%. As of June 7, 2000, the interest rate of this loan would have been 8.0%;

- approximately $3.2 million to pay down debt under our revolving bank credit facility. As of June 7, 2000, the interest rate of this credit facility was 7.0%; and

- the remaining net proceeds for our working capital and other general corporate purposes, including sales and marketing expenses and research and development expenditures. The amount and timing of these expenditures will vary depending on a number of factors, including future revenue growth, if any, the amount of cash we generate from operations and the progress of our product development efforts.

If the opportunity arises, we may use a portion of the net proceeds to acquire or invest in related businesses, products and technologies. We currently have no commitments or agreements for any material acquisition of, or investment in, any third party. Pending any use of the net proceeds for the above purposes, we intend to invest the funds in short-term, interest-bearing, investment grade securities. See "Business -- Our Strategy."

We have paid the following dividends per share during the five fiscal years ended August 31, 1999 and the six months ended February 29, 2000:

Prior to the closing of this offering, we will declare a dividend of C$26.0 million (approximately $17.6 million) to the holders of Class "A" and Class "F" shares. Holders of Class "F" shares will receive a cash payment of C$476,616 (approximately $322,000). We will issue promissory notes to the holders of Class "A" shares for an aggregate principal amount of C$25.5 million (approximately $17.3 million). The promissory notes will bear no interest and will be repaid from the proceeds of this offering. We do not currently anticipate paying additional dividends for at least the next three years. Our current intention is to reinvest our earnings in our business long-term growth. Any future determination by us to pay dividends will be at the discretion of our board of directors and in accordance with the terms and conditions of any outstanding indebtedness and will depend upon our financial condition, results of operations, capital requirements and such other functions as our board of directors considers relevant.

CAPITALIZATION

The following table sets forth our capitalization as of February 29, 2000:

- on a pro forma basis, giving effect to the exchange of all Class "A" shares into 38,000,000 multiple voting shares, the issuance of 485,537 Class "F" shares to employees under outstanding subscription agreements, the exchange of 709,605 Class "F" shares into subordinate voting shares, and the exchange of all Class "G" shares into 800,000 preferred shares series 1, and the declaration of a $17.6 million dividend, all of which will occur prior to the closing of this offering; and

- on a pro forma as adjusted basis, giving effect to the sale of 6,000,000 subordinate voting shares offered by this prospectus at an assumed initial public offering price of $21.00 and the application of the estimated net proceeds from this offering.

                                                                   AS AT FEBRUARY 29, 2000

The table above does not include:

- 25,766 subordinate voting shares issuable upon conversion of the preferred shares series 1, assuming a conversion price of $21.00 per share, which may occur at our option on November 30, 2000; and

- 4,470,961 subordinate voting shares reserved for future issuances under our stock option plan, including 581,280 subordinate voting shares to be issued upon the exercise of stock options to be granted prior to the closing of this offering at an exercise price equal to the initial public offering price.

DILUTION

If you invest in our subordinate voting shares, your interest will be diluted by the amount of the difference between the public offering price per subordinate voting share and the pro forma as adjusted net tangible book value per subordinate voting share of this offering.

Our pro forma net tangible book value as of February 29, 2000 was $(739,000), or $(0.02) per subordinate voting share. Pro forma net tangible book value per subordinate voting share is equal to our total tangible assets less total liabilities, divided by the number of outstanding subordinate voting shares and multiple voting shares combined.

After giving effect to our sale of 6,000,000 subordinate voting shares in this offering at an assumed initial public offering price of $21.00 per subordinate voting share and after deducting the estimated underwriting commissions and estimated offering expenses, our pro forma as adjusted net tangible book value as of February 29, 2000 is $115.4 million, or $2.58 per share. This figure represents an immediate increase in our pro forma net tangible book value of $2.60 per subordinate voting share to existing shareholders and an immediate dilution of $18.42 per subordinate voting share to new investors. Dilution is determined by subtracting the pro forma as adjusted net tangible book value per subordinate voting share after this offering from the amount of cash a new investor pays for a subordinate voting share. The following table illustrates this dilution to new investors:

Assumed initial public offering price per subordinate voting
  share.....................................................               $21.00

If the underwriters exercise their option to purchase additional subordinate voting shares in this offering, our pro forma adjusted net tangible book value as at February 29, 2000 would be $133.0 million, or $2.92 per subordinate voting share, representing an immediate increase in net tangible book value to our existing shareholders of $2.94 per share and immediate dilution to new investors of $18.08 per share.

The following table summarizes as of February 29, 2000 and after giving effect to the capital reorganization described above, the differences between the number of shares purchased from EXFO, the total consideration paid and the average price per share paid by our existing shareholders and by the new investors in this offering, before deducting the estimated underwriting commissions and estimated offering expenses:

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
AND RESULTS OF OPERATIONS

The following discussion and analysis should be read in conjunction with our consolidated financial statements and the related notes, which are included elsewhere in this prospectus.

OVERVIEW

EXFO was incorporated on September 18, 1985. We have expanded from a company that provided low cost handheld fiber-optic test and measurements instruments into a company that provides an extensive line of test, measurement and monitoring products. Our original products were focused primarily on the needs of installers and operators of fiber-optic networks. In 1996, we supplemented our product line with an extensive line of scientific products that is dedicated to the manufacturing and research and development markets in the fiber-optic industry. Our scientific products tend to be more complex and higher priced. In 1999, we entered the market for remote fiber test systems. Remote fiber test systems allow carriers to deploy monitoring equipment throughout their networks in order to monitor the status of their fiber-optic networks.

We sell our products to customers through our direct sales force and indirectly through distribution channels. For products where the software is incidental, we recognize sales when the products are delivered with appropriate provisions made for estimated returns, warranties and support obligations. For products where software is not incidental, sales are separated into two components, product sales and customer support sales. The product sales are recognized when the products are delivered with provisions made for estimated returns and warranties. The customer support sales are deferred based on prices for similar maintenance contracts and recognized ratably over the period of the support arrangement, except where support is provided within one year of delivery, costs of providing this support are insignificant and accrued at the time of delivery and no upgrades of software are provided.

We deliver products to a large number of customers. No customer accounted for more than 6.8% of total sales for the year ended August 31, 1999 or 5.5% of total sales for the six months ended February 29, 2000. During the twelve months ended May 31, 2000, we shipped and invoiced products within an average of 30 days after the acceptance of an order.

The market for fiber-optic test, measurement and monitoring instruments is highly competitive and we anticipate that the average selling prices of our existing products will decrease in future periods, although the timing and amount of these decreases cannot be predicted with any certainty. Those decreases in the average selling price may be offset by continued product improvement and new product introductions.

Cost of sales include raw materials, salaries and related expenses for direct and indirect manufacturing personnel and manufacturing overhead. Cost of sales may increase as a percentage of sales in future periods due to the high demand for fiber-optic components, our use of more sophisticated and complex fiber-optic components, as well as the planned expansion of our manufacturing facilities. However, this increase may be mitigated by increased purchasing power and productivity gains related to our expansion.

Our gross margin varies among our products and we expect that our overall gross margin will fluctuate from period to period as a result of shifts in product mix, anticipated decreases in average selling prices and our ability to introduce new products.

Gross research and development expenses consist primarily of salaries and related expenses for engineers and other technical personnel and fees paid to third-party consultants. We are entitled to research and development tax credits granted by the Canadian federal government and the government of the province of Quebec. Federal tax credits are earned on qualified Canadian research and development expenditures at a rate of 20% and can only be used to offset federal income taxes otherwise payable. Provincial tax credits, which are refundable, are earned on qualified research and development salaries in the province of Quebec at a rate of 20%. Additional refundable provincial research and development tax credits are earned at a rate of up to 20%. These additional tax credits are reduced to nil, on a pro-rata basis, as total assets increase from C$25.0 million to C$50.0 million. We are also entitled to government grants resulting from agreements entered into with the government of the province of Quebec. See "Liquidity and Capital Resources." Research and development tax

24

credits and certain government grants are recorded as a reduction of gross research and development expenses. We believe that continued investment in research and development is critical to our long-term success. We expect that our gross research and development expenses will increase with sales in future periods. The rate of research and development tax credits will decrease as our total assets continue to grow.

Selling and administrative expenses consist primarily of salaries and related expenses for personnel, sales commissions, travel expenses, marketing programs, professional services, management information systems, human resources and other corporate expenses. We intend to expand our sales organization by opening additional international sales offices and service centers. We expect that, in support of our continued growth, the expansion of our sales efforts and our operations as a public company, selling and administrative expenses will continue to increase with sales for the foreseeable future.

In February 2000, in order to expand our portfolio of test equipment, we acquired Nortech Fibronic Inc., a company specializing in fiber-optic testing and temperature sensing. In connection with the acquisition, we recorded $2.5 million of goodwill, which will be amortized over five years.

Our consolidated financial statements are prepared in accordance with Canadian GAAP, which differs in certain respects from U.S. GAAP. For a description of the material differences between Canadian GAAP and U.S. GAAP in regards to our consolidated financial statements, see note 21 to our consolidated financial statements included elsewhere in this prospectus. All dollar amounts are expressed in U.S. dollars. Effective September 1, 1999, we adopted the U.S. dollar as the reporting currency for our consolidated financial statements. The financial statements for all periods prior to fiscal 2000, are presented in U.S. dollars in accordance with a translation of convenience method under Canadian GAAP using the representative exchange rate as at August 31, 1999 of $1.00 = C$1.4958. The historical results below are not necessarily indicative of the results to be expected for any future period.

We believe that period-to-period comparisons of our historical operating results should not be relied upon as being a good indication of our future performance. Our prospects must be considered in light of the risks experienced by companies in new and rapidly evolving markets like ours. We cannot assure you that we will successfully address the risks and challenges that we face. Although we have experienced significant sales growth recently, we may not be able to sustain this trend. Furthermore, we may not achieve or maintain profitability in the future.

SIX MONTHS ENDED FEBRUARY 29, 2000 COMPARED TO SIX MONTHS ENDED FEBRUARY 28,
1999

SALES

Sales increased 55.4% from $18.7 million for the six months ended February 28, 1999 to $29.1 million for the six months ended February 29, 2000. This growth was primarily due to the higher demand for our scientific products and a general increase in sales of our other products. Accepted orders increased 74.2% from $18.2 million for the six months ended February 28, 1999 to $31.7 million for the six months ended February 29, 2000.

GROSS MARGIN

Gross margin increased to 67.0% of sales for the six months ended February 29, 2000 from 62.5% of sales for the corresponding period in 1999. The improvement of the gross margin resulted primarily from increased economies of scale in our production process and from higher margin product sales. The expected expansion of our manufacturing capacity to address future volume growth may have an adverse impact on our gross margin until we can absorb the additional fixed manufacturing expenses through increased sales.

SELLING AND ADMINISTRATIVE

Selling and administrative expenses increased to $9.9 million during the six months ended February 29, 2000 compared to $6.0 million for the corresponding period in 1999, an increase of 66.6%. As a percentage of sales, selling and administrative expenses amounted to 34.1% for the six months ended February 29, 2000 compared to 31.8% of sales for the six months ended February 28, 1999. The $3.9 million increase in selling and

26

administrative expenses reflects the hiring of additional sales, marketing and administrative personnel and commissions on higher sales volume.

RESEARCH AND DEVELOPMENT

Gross research and development expenses amounted to $4.7 million for the six months ended February 29, 2000 compared to $2.8 million for the corresponding period in 1999, an increase of 66.8%. As a percentage of sales, gross research and development expenses amounted to 16.1% for the six months ended February 29, 2000 compared to 15.0% for the corresponding period in 1999. The increase in gross research and development expenses reflects the hiring of additional research and development personnel and the outsourcing of non-critical research and development projects.

Tax credits and grants earned from federal and provincial governments for our research and development activities increased 43.9% to $1.5 million for the six months ended February 29, 2000 compared to $1.0 million for the six months ended February 28, 1999. Research and development tax credits and grants as a percentage of gross research and development expenses amounted to 31.4% for the six months ended February 29, 2000 compared to 36.4% for the six months ended February 28, 1999. The percentage decrease is due to the reduction of the rate of the government tax credits due to the growth in our total assets.

As a result of these factors, net research and development expenses increased 79.8% to $3.2 million for the six months ended February 29, 2000 compared to $1.8 million for the corresponding period in 1999. Net research and development expenses increased as a percentage of total sales to 11.1% for the six months ended February 29, 2000 compared to 9.6% for the six months ended February 28, 1999.

INCOME TAXES

Our effective tax rate amounted to 33.7% for the six months ended February 29, 2000 compared to 30.1% for the six months ended February 28, 1999. The increase is due to non-taxable items in the six months ended February 28,1999, which lowered the effective tax rate of that period.

YEAR ENDED AUGUST 31, 1999 COMPARED TO YEAR ENDED AUGUST 31, 1998

SALES

Sales increased 33.4% from $31.6 million in fiscal 1998 to $42.2 million in fiscal 1999. The increase in sales was due primarily to increased sales of our IQ-200 Optical Test System product and related modules and the overall growth in demand for test and measurement products.

GROSS MARGIN

Gross margin increased from 64.1% of sales in fiscal 1998 to 64.4% of sales in fiscal 1999. The improvement of the gross margin resulted primarily from increased economies of scale in our production process and increased sales of higher margin products.

SELLING AND ADMINISTRATIVE

Selling and administrative expenses increased from $9.9 million in fiscal 1998 to $13.3 million in fiscal 1999, an increase of 34.2%. As a percentage of sales, selling and administrative expenses amounted to 31.5% in fiscal 1999 and 31.3% in fiscal 1998. The $3.4 million increase in fiscal 1999 reflects the hiring of additional sales personnel, product managers, marketing and administrative personnel, for the opening of offices in Asia and commissions on higher sales volume.

RESEARCH AND DEVELOPMENT

Gross research and development expenses amounted to $6.4 million in fiscal 1999 compared to $4.4 million in fiscal 1998, an increase of 45.0%. As a percentage of sales, gross research and development expenses amounted to 15.2% in fiscal 1999 and 13.9% in fiscal 1998. The increase in gross research and development

27

expenses, due primarily to additional personnel, reflects our continued focus on research and development activities.

Tax credits and grants earned from federal and provincial governments for our research and development activities increased 49.1% to $2.1 million in fiscal 1999 compared to $1.4 million in fiscal 1998. Research and development tax credits and grants as a percentage of gross research and development expenses amounted to 32.5% in fiscal 1999 compared to 31.6% in fiscal 1998.

As a result of these factors, net research and development expenses increased 43.2% to $4.3 million in fiscal 1999 compared to $3.0 million for fiscal 1998. Net research and development expenses increased as a percentage of total sales to 10.2% for fiscal 1999 compared to 9.5% for fiscal 1998.

INCOME TAXES

Our effective income tax rate decreased to 30.0% in fiscal 1999 compared to 34.4% in fiscal 1998. The decrease was due to non-taxable items in fiscal 1999.

YEAR ENDED AUGUST 31, 1998 COMPARED TO YEAR ENDED AUGUST 31, 1997

SALES

Sales increased 29.1% from $24.5 million in fiscal 1997 to $31.6 million in fiscal 1998. The increase in sales was primarily due to increased unit sales of our IQ-200 Optical Test System product and related modules and the overall growth in sales for test and measurement products.

GROSS MARGIN

Gross margin increased from 60.6% of sales in fiscal 1997 to 64.1% of sales in fiscal 1998. The gross margin increase is due primarily to a reduction in raw materials costs obtained by renegotiating supplier arrangements and by aggregating the number of our suppliers.

SELLING AND ADMINISTRATIVE

Selling and administrative expenses increased from $7.8 million in fiscal 1997 to $9.9 million in fiscal 1998, an increase of 26.5%. As a percentage of sales, selling and administrative expenses amounted to 31.3% in fiscal 1998 compared to 32.0% in fiscal 1997. The increase of $2.1 million in 1998 reflects the hiring of additional sales personnel, product managers, marketing and administrative personnel and commissions on higher sales volume.

RESEARCH AND DEVELOPMENT

Gross research and development expenses amounted to $4.4 million in fiscal 1998 compared to $2.8 million in fiscal 1997, an increase of 60.0%. As a percentage of sales, gross research and development expenses amounted to 13.9% in fiscal 1998 and 11.2% in fiscal 1997. The increase in gross research and development expenses, primarily due to additional personnel, reflects our continued focus on research and development activities.

Tax credits and grants earned from federal and provincial governments for our research and development activities increased 19.9% to $1.4 million in fiscal 1998 compared to $1.2 million in fiscal 1997. Research and development tax credits and grants as a percentage of gross research and development expenses amounted to 31.6% in fiscal 1998 compared to 42.2% in fiscal 1997. The percentage decrease is due to the reduction of the rate of government tax credits due to the growth in our total assets.

As a result of these factors, net research and development expenses increased 89.3% to $3.0 million for fiscal 1998 compared to $1.6 million for fiscal 1997. Net research and development expenses increased as a percentage of sales to 9.5% for fiscal 1998 compared to 6.5% for fiscal 1997.

28

INCOME TAXES

Our effective income tax rate remained relatively constant at 34.4% in fiscal 1998 compared to 34.0% in fiscal 1997.

Quarterly sales figures have varied in the past and may continue to vary significantly in the future. From time to time, we receive large orders which require us to build significant inventories to aggregate for shipment. For example, in the three months ended May 31, 1998, a large order of portable products was delivered, explaining the high level of sales achieved in that quarter. Change in demand for our products may also cause fluctuations quarter-over-quarter. For example, the increased demand for our scientific products generally explained the increase in sales for the three months ended February 29, 2000. Other factors that may cause quarter-over-quarter fluctuations in sales include:

- timing of sales;

- timing of customer orders;

- delivery date requested by the customer;

- unexpected delay in introducing new products;

- shortage in raw materials supply;

- delay in ramping up our manufacturing for high demand products;

- cancellation of orders by our customers;

- customers' capital budgets available for purchasing our products; and

- competitors' products and prices.

Consequently, these fluctuations in sales can cause significant fluctuations in our gross margin as well as quarterly earnings.

Gross margin has also varied in the past and may continue to vary significantly in the future depending on the mix of products sold, our capacity to introduce new products with higher margins, our ability to achieve economies of scale in our production process, the impact of large orders with reduced margins, fluctuations in raw materials costs and increases in personnel costs. For nine of the ten quarters, the gross margins were in a range of 62.3% to 68.1%. Gross margins for the quarter ended May 31, 1998 was 60.5%, due to the delivery in March 1998 of a large order of portable products with lower margins.

30

As a result of the factors listed above and elsewhere in the "Risk Factors" section of this prospectus, it is possible that in some future periods our results of operations may fall below our expectations as well as the expectations of public market analysts and investors. In addition, we plan to significantly increase our operating expenses to expand our manufacturing, sales and marketing, customers support, administration and research and development activities. If sales fall below our expectations in any quarter and we are unable to reduce our spending appropriately, our operating results would be lower than expected.

LIQUIDITY AND CAPITAL RESOURCES

Since our inception, we have financed operations and met our capital expenditure requirements primarily through cash flows from our operations, research and development tax credits and government grants. Cash flows from operating activities were $4.6 million for fiscal 1997, $3.2 million for fiscal 1998 and $3.7 million for fiscal 1999. Cash flows used for operating activities were $2.1 million for the six months ended February 29, 2000, reflecting the large increase in accounts receivable and inventories. The increase in accounts receivable is in line with the increase in sales in the quarter ended February 29, 2000. Increased levels of inventory were required to service this growth in sales as well as the expected growth in future sales. As at February 29, 2000, we had cash and cash equivalents of $539,000 and working capital of $13.6 million.

Net cash used in investing activities was $1.6 million for fiscal 1997, compared to $2.0 million for fiscal 1998, $1.2 million for fiscal 1999 and $2.3 million for the six months ended February 29, 2000. The cash used in fiscal 1997, 1998 and 1999 was primarily for capital expenditures and short-term investments. The cash used for the six months ended February 29, 2000 was primarily for capital expenditures and the Nortech Fibronic Inc. acquisition. On February 4, 2000, we acquired Nortech Fibronic Inc., for a total consideration of approximately C$4.1 million of which approximately C$3.0 million was paid in cash, C$800,000 of which was paid by the issuance of Class "G" shares of EXFO, which will be converted into preferred shares series 1 prior to the closing of this offering and of which C$200,000 was paid by a non-interest-bearing debenture payable in November 2000. We currently have a commitment to purchase a building located in Vanier, Quebec for C$4.9 million and expect to make additional capital expenditures in fiscal 2000 of approximately $5.8 million, primarily for improvements to the building being acquired, the acquisition of production equipment, the acquisition of research and development equipment and new management information systems.

Net cash used in financing activities are primarily due to dividends paid in fiscal 1999 and fiscal 1998 and to dividends paid and repayments of bank advances and long-term debt in fiscal 1997. The total amount of bank advances outstanding increased to $5.4 million as at February 29, 2000 compared to nil at August 31, 1999. This substantial increase is due in part to the acquisition of Nortech Fibronic Inc., for which we used approximately $2.1 million under our operating loan facility. The balance of the increase results form advances drawn under our available lines of credit in order to finance working capital requirements, namely inventories and accounts receivable. In addition, we expect to declare a dividend of C$26.0 million (approximately $17.6 million) immediately prior to the closing of this offering. We do not expect to pay any additional dividends for at least the next three years.

Pursuant to an agreement with the Quebec Minister of Industry, Commerce, Science and Technology, the Minister agreed to provide grants for job creation up to a maximum of approximately C$2.2 million over the period from January 1, 1998 through December 31, 2002. These grants are payable based on the number of full time jobs created during the period. In addition the Minister agreed to contribute grants, up to a maximum of C$600,000 towards interest costs incurred for the period from January 1, 1998 through December 31, 2002. Among other conditions, each job created must be maintained for a minimum period of five years from the date of hire. Should this or other conditions not be met, the Minister may enforce various recourse options including suspension or cancellation of the agreement or repayment of amounts received by us. See "Risk Factors -- We may not be able to sustain our research and development activities as our research and development credits and grants decline" and "Risk Factors -- Unexpected declines in our research and development credits and grants may have an adverse effect on our business."

We have available credit facilities that provide for advances of up to C$11.5 million under lines of credit and C$3.0 million as an operating loan. These facilities, which must be renewable annually, bear interest at margins

31

over prime rate ranging between nil and 1.25%. Accounts receivable, inventories and all tangible and intangible assets have been pledged as security against these facilities. As at February 29, 2000, an amount of C$7.7 million has been drawn against the facilities. The interest rate of credit facilities drawn in Canadian dollars is the Canadian prime rate (7.5% as at June 7, 2000) and the credit facilities drawn in United States dollars is the U.S. prime rate (10.0% as at June 7, 2000).

We expect to devote substantial resources to continue our research and development efforts, expand our sales, support, marketing and product development organizations, expand internationally and build the infrastructure necessary to support our growth. As a result, we anticipate that capital expenditures will continue to increase in absolute dollars for at least the next three years. We believe that the net proceeds from this offering, together with our current cash and cash equivalents, will be sufficient to fund our operations for at least the next 12 months. Prior to or following the end of this period, we may need or choose to raise additional funds or seek other financing arrangements in order to facilitate more rapid expansion, including significant increases in personnel and office facilities, to develop new or enhance existing products or services, to respond to competitive pressures, or to acquire or invest in complementary businesses, technologies, services or products. In the event that additional financing is required, we may not be able to raise it on acceptable terms or at all.

NEW ACCOUNTING STANDARDS

In 1998, the Financial Accounting Standards Board issued Statement of Financial Accounting Standard, SFAS No. 133, "Accounting for Derivative Instruments and Hedging Activities". The standard, which must be applied prospectively, is effective for all fiscal quarters of all fiscal years beginning after June 15, 2000. Under SFAS No. 133, all of our forward exchange contracts would be carried on the balance sheet at fair value and any unrealized gains or losses at each balance sheet date would be included in other comprehensive income.

On December 3, 1999, the Securities and Exchange Commission issued Staff Accounting Bulletin ("SAB")101, "Revenue Recognition." SAB 101, as amended by SAB 101A, is effective commencing in the first fiscal quarter of the first fiscal year beginning after December 15, 1999. The implementation of this SAB is not expected to have any material effect on our financial statements or revenue recognition policy on future periods.

MARKET RISK

Currency Risks

We are exposed to currency risk as a result of our export of products manufactured in Canada, substantially all of which are denominated in U.S. dollars. Our exposure to foreign exchange rate fluctuations is partially hedged by operating expenses of our U.S. and European subsidiaries and the portion of our raw materials purchased which are denominated in U.S. dollars. In addition, we frequently enter into forward exchange contracts to sell U.S. dollars at fixed forward rates in exchange for Canadian dollars in order to manage the risk of exchange rate fluctuations between the Canadian and U.S. dollars on cash flows related to anticipated future revenue streams and firmly committed future sales transactions denominated in U.S. dollars. We do not enter into forward exchange contracts for trading purposes.

The following table summarizes the forward exchange contracts in effect as at February 29, 2000, classified by expected transaction dates, none of which exceed two years. The table below presents the notional amounts of such contracts (in thousands of dollars) along with the weighted average contractual forward rates under such contracts. The notional amounts of such contracts are used to calculate the contractual payments to be exchanged under these contracts.

CORPORATE INFORMATION

CORPORATE HISTORY

EXFO was incorporated on September 18, 1985 pursuant to the Canada Business Corporations Act. Since that date, we have amended our articles on various occasions:

- on August 9, 1996, to add the English version of EXFO Electro-Optical Engineering Inc. to our name;

- on August 31, 1998, to change our name from Ingenierie Electro-Optique EXFO Inc./EXFO Electro-Optical Engineering Inc. to EXFO Ingenierie Electro-Optique Inc./EXFO Electro-Optical Engineering Inc. and to create the Class "F" shares;

- on September 2, 1998, to effect a split of our Class "A" shares;

- on September 3, 1998 to effect a split of our Class "E" shares and to convert our Class "E" shares into Class "A" shares;

- on February 7, 2000, to create our Class "G" shares;

- on April 13, 2000, to amend our articles of incorporation in order to:

-- repeal pre-emptive rights in favor of our shareholders;

-- repeal our right to have a lien over shares of shareholders who are indebted to us;

-- amend the rights of the holders of Class "F" shares; and

-- repeal rights of first refusal in favor of our shareholders; and

- on June 8, 2000, to amend our articles of incorporation in order to:

-- eliminate the private-company restrictions; and

-- provide for a board of directors of a minimum of three and a maximum of 12 directors.

Prior to the closing of this offering, we will file articles of amendment to create a class of multiple voting shares, a class of subordinate voting shares and a class of preferred shares issuable in series and to exchange the Class "A" shares into multiple voting shares, the Class "F" shares into subordinate voting shares and the Class "G" shares into preferred shares series 1.

In 1996, GEXFO Investissements Technologiques inc., a company controlled by Germain Lamonde, acquired a majority interest in GAP Optique S.A., a Swiss limited liability company carrying out activities in the field of fiber-optic testing and measurement technology. In 1996, GEXFO, EXFO, GAP Optique and the University of Geneva entered into agreements whereby GAP Optique, EXFO and GEXFO obtained worldwide exclusive rights to commercially develop, manufacture and market specified technologies relating to fiber-optic telecommunications testing and measurement instruments developed by the University of Geneva. In addition, GAP Optique, EXFO and GEXFO acquired priority rights over the marketing of fiber-optic telecommunication testing and measurement instruments prototypes designed by the University of Geneva. This agreement was renegotiated under similar terms and conditions in 1999 for a five-year term. On June 1, 2000, we acquired the 85% interest held by GEXFO in GAP Optique for a consideration equal to its book value of approximately $16,000 and GEXFO transfered all of its rights in the agreements to us.

In February 2000, we acquired all of the shares of Nortech Fibronic Inc., a company specializing in fiber-optic testing and temperature-sensing for a total consideration of $2.8 million of which $2.1 million was paid in cash. We also issued C$800,000 (approximately $541,000) of Class "G" shares and a debenture of C$200,000 (approximately $135,000) bearing no interest and payable on November 30, 2000.

CAPITAL REORGANIZATION

As of June 8, 2000, our authorized share capital was composed of an unlimited number of Class "A" shares, Class "B" shares, Class "C" shares, Class "D" shares, Class "E" shares, Class "F" shares and Class "G" shares, of which 38,000,000 Class "A" shares, 709,605 Class "F" shares and 800,000 Class "G" shares were issued and outstanding.

Prior to the closing of this offering, we will modify our authorized share capital to:

- an unlimited number of subordinate voting shares without par value;

- an unlimited number of multiple voting shares without par value; and

34

- an unlimited number of preferred shares without par value, issuable in series.

As a result of the reorganization:

- the 38,000,000 Class "A" shares will be exchanged into 38,000,000 multiple voting shares;

- the 709,605 Class "F" shares will be exchanged into 709,605 subordinate voting shares; and

- the 800,000 Class "G" shares will be exchanged into 800,000 preferred shares series 1.

The exchange of Class "A" shares into multiple voting shares, of Class "F" shares into subordinate voting shares and of Class "G" shares into preferred shares series 1 is part of the capital reorganization and will not involve any disbursement of funds. Likewise, the conversion of the preferred shares series 1 will not involve any disbursement of funds and is based on a predetermined formula. See "Description of Share Capital -- Preferred Shares Series 1."

BUSINESS

OVERVIEW

We are a leading designer, manufacturer and marketer of fiber-optic test, measurement and monitoring instruments for the telecommunications industry. We believe that we are the largest manufacturer of test, measurement and monitoring instruments that is exclusively dedicated to fiber optics. Fiber-optic test, measurement and monitoring equipment is mainly used by optical network carriers, manufacturers, and research and development laboratories to measure the physical characteristics of optical fiber and related hardware.

EXFO was 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 and monitoring instruments. We currently employ more than 650 employees and our products are distributed in over 70 countries. We have been profitable each year of our 15-year existence.

We develop products principally for two markets. Our Portable and Monitoring Division provides solutions primarily to telecommunications carriers, cable television companies, public utilities, private network operators, as well as third-party installers and equipment rental companies. Our Scientific Division, established in 1996, designs an extensive line of more sophisticated and higher performance instruments for manufacturers of optical components, value-added optical modules and optical networking systems. Our Scientific Division also designs products for research and development markets. We leverage technologies that we develop for our Scientific Division into products for our Portable and Monitoring Division.

In 1999, we released the first version of our remote fiber test system, which surveys and monitors a fiber-optic network. Our remote fiber test system consists of rack-mounted remote test units, which are strategically deployed along a fiber-optic network and a test system controller that retrieves information from as many remote test units as required. The test system controller is typically located inside a network operations center. The information obtained from these remote test units is combined with data from a geographic information system in our software to pinpoint the exact location of a system failure.

We have received 40 industry and commerce awards. Every year since 1995, we have been recognized as one of the 50 Best-Managed Private Companies in Canada by Arthur Andersen Consulting and the Financial Post. We have maintained ISO 9001 certification since 1994.

The past decade has witnessed an explosive growth in the volume of data traffic largely due to the soaring popularity of the Internet and related bandwidth-intensive applications. According to the Angus Reid Group, a leading market research company, the number of Internet users around the world is expected to increase from 300 million in early 2000 to 1 billion by 2005. Ryan, Hankin & Kent, a leading telecom market research firm, forecasts that Internet traffic will increase from 350,000 terabytes, or trillions of bytes, per month at the end of 1999 to more than 15 million terabytes per month in 2003, representing a compound annual average growth rate of 156%.

The dramatic increase in Internet users and traffic has created a tremendous need for high-bandwidth communications networks. To meet this increasing demand for bandwidth, many communications service providers are designing and installing new networks based on optical fiber, deploying additional fiber within their existing networks, or using advances in optical technology such as dense wavelength division multiplexing, or DWDM. DWDM involves combining beams of light of slightly different wavelengths through a single fiber, with each wavelength carrying its own stream of information. This technique requires separate laser sources for each signal or channel and more complex equipment to control and amplify the signal in the network. Some DWDM systems can carry as many as 160 separate channels per optical fiber. According to Ryan, Hankin & Kent, the global DWDM and optical networking market is expected to increase from $13 billion in 2000 to $41 billion in 2003.

Until recently, most of the fiber deployed had been dedicated to long-haul and inter-office networks. The fiber-optic industry, however, is beginning to shift its focus towards more complex metropolitan networks for

36

business-to-business applications and fiber-to-the-curb networks for residential applications. These networks require more complex optical systems than long-haul and inter-office networks.

Manufacturers are finding it difficult to keep pace with carrier demand for optical fiber and optical networking equipment. At the end of 1999, 22.7 million kilometers of fiber had been deployed in North America alone and this figure is expected to reach 68.1 million kilometers by 2004, according to Kessler Marketing Intelligence, a leading fiber-optic market research company. Corning Incorporated, a world-leading manufacturer of optical fiber, announced earlier this year that it plans to invest $750 million in order to expand its optical fiber manufacturing capacity by 50%. Nortel Networks Corporation, a leading supplier of DWDM equipment, announced in November 1999 that it will invest $400 million to triple its manufacturing capacity of high-performance optical Internet systems.

Optical Test, Measurement and Monitoring Equipment Market

Conventional test, measurement and monitoring instruments used by telecommunications carriers and manufacturers of communications equipment were designed for electrical transmission systems and are unsuitable for optical networking. Unlike traditional electrical transmission systems, which transmit electrical signals along copper wires, fiber-optic transmission systems use pulses of light along glass or plastic fiber, often referred to as optical fiber. When light travels along optical fiber and through the optical components and systems that link, optical fibers together, it is subject to unwanted effects such as reflection, attenuation, noise and various types of dispersion, all of which degrade signal quality and reduce transmission performance. Fiber-optic test, measurement and monitoring equipment is critical for measuring these effects and helping communications carriers and manufacturers of optical components, value-added optical modules and optical networking systems ensure network performance and reliability. The following are the main uses for fiber-optic test, measurement and monitoring equipment:

- NETWORK INSTALLATION. Carriers and third-party network installers use test and measurement instruments to ensure the quality of networks as they are being deployed.

- NETWORK MAINTENANCE AND REPAIR. Carriers and third-party service companies use test and measurement instruments to diagnose and repair problems within an optical network.

- NETWORK MONITORING. By continually monitoring the quality of an optical signal as it passes through a network, carriers can reduce downtime through faster detection and diagnosis of network problems.

- MANUFACTURING. Manufacturers in the fiber-optic industry use test measurement equipment during production and assembly as well as for quality control and conformity testing.

- RESEARCH AND DEVELOPMENT. Developers and manufacturers in the fiber-optic industry require sophisticated test and measurement equipment during the prototyping stage of product development.

MARKET OPPORTUNITY

Demand for fiber-optic test, measurement and monitoring equipment is driven by the following key trends:

INCREASED PRODUCTION OF CABLE AND FIBER. Cable and fiber manufacturers are increasing production of optical fiber in order to meet the growing demand from telecommunications carriers. Manufacturers of optical fiber require additional test and measurement equipment to fulfill their product development and quality control requirements. Fiber and cable manufacturers require improved test and measurement instruments as they develop better products to respond to the demand for increased transmission speeds and higher DWDM channel counts.

QUALIFICATION OF EXISTING PLANTS AND FURTHER DEPLOYMENT OF FIBER. Carriers are upgrading their existing fiber networks, deploying more fiber and using more advanced optical transmission technologies, such as DWDM, to handle the increased demand for bandwidth. Test, measurement and monitoring equipment is required for the qualification of existing fiber plants; for the installation, maintenance and troubleshooting of newly deployed fiber and for the installation and verification of DWDM networks.

MORE COMPLEX OPTICAL NETWORKS. The trend towards more complex optical networks has rendered test, measurement and monitoring increasingly important. First-generation fiber-optic networks carried only one wavelength and demanded simpler loss measurements. Rapid advances in fiber-optic data transmission are producing networks with higher data speeds, higher power transmission lasers, greater distances without

37

reamplification, more narrowly spaced DWDM channels and higher channel counts. Optical equipment used in these new and more complex networks requires the verification of several parameters for each DWDM wavelength and has created a demand for more complex test, measurement and monitoring instruments.

CONTINUED WORLDWIDE TELECOMMUNICATIONS DEREGULATION. Continued deregulation of telecommunications markets has forced many carriers to upgrade their networks to compete for customers. In order to compete, carriers must offer services to provide increased bandwidth with greater reliability, while at the same time reducing costs. To respond to these market conditions, carriers are increasingly using sophisticated test, measurement and monitoring equipment to ensure network quality, as fiber networks are being deployed and to reduce restoration time for operating networks.

GROWING USE OF CUSTOMIZED AUTOMATED TEST SYSTEMS. Optical components, value-added optical modules and optical networking systems are typically assembled and aligned by hand. This task involves the extensive use of optical measurement during the manufacturing and assembly process as well as during final testing and certification. As systems become more complex, the number of individual tests that must be performed increases dramatically. Testing and certification procedures represent a significant portion of the total time required to manufacture optical components, value-added optical modules and optical networking systems. As a result, manufacturers are continually looking for ways to automate their test and certification procedures. Although optical components, value-added optical module and optical networking systems manufacturers have typically integrated commercially available test instruments into customized, automated test systems in-house, they are increasingly turning to third-party test and measurement manufacturers to provide innovative solutions, so that they can focus scarce technical resources on product development and production.

MORE STRINGENT INDUSTRY REQUIREMENTS. Industry standards committees, such as the Telecommunication Industry Association, International Electrotechnical Commission and International Telecommunications Union, are adopting more stringent technical specifications to address increased transmission rates, greater power and higher channel counts being demanded by the industry. Manufacturers of optical components, value-added optical modules and optical networking systems, as well as network carriers and installers, all require improved test, measurement and monitoring solutions to meet the demands of advanced optical networks.

THE EXFO SOLUTION

We believe that we offer the most extensive range of products in the fiber-optic test, measurement and monitoring industry. Our success has been largely based on our exclusive focus on fiber-optic test, measurement and monitoring instruments. We have developed optical technologies and advanced testing algorithms that we leverage across our various product lines.

The success of our solution is based on the following key attributes:

MODULAR SYSTEM DESIGN. In 1996, we introduced the first products designed around our modular system design. These system designs consist of Windows-based platform that can accommodate several data acquisition test modules. We have since developed products for each of our divisions based on the same modular design. Our modular design provides the following advantages:

- Unlike stand-alone units, new test modules can be rapidly developed to address the changing requirements of the industry.

- As customers' testing requirements change, they can purchase additional modules that are compatible with their previously purchased platforms, thus protecting their initial investments.

- Our standard graphical user interface reduces training costs because customers are familiar with previously acquired software products.

- The flexibility of our systems allows customers to develop customized and automated solutions directed at specific testing requirements.

HIGH DEGREE OF TECHNOLOGICAL INNOVATION. We have continually been at the forefront of fiber-optic test, measurement and monitoring technology. For example, we were the first in our industry to develop and commercialize a number of fiber-optic test and measurement products:

- All-in-one loss test set. In 1992, we launched the first handheld unit for automated bidirectional loss testing. This rugged and compact loss test set combined four high-performance instruments in a single unit. The all-in-one loss test set, based upon our patented technology, allowed the user to save a considerable amount of time in the field. In 1997, we released a second-generation of this product which combines six instruments in a single unit.

- Portable modular platform. In 1996, we released the FTB-300 Universal Test System, which was the first portable test platform in our industry based on a modular design. This portable modular platform, which includes multiple optical testing technologies, enables the user to carry out numerous test operations for outside plant installation, maintenance and troubleshooting applications.

- Portable polarization mode dispersion analyzer. In 1996, we introduced the industry's first handheld polarization mode dispersion analyzer. Polarization mode dispersion is a physical phenomenon inherent to optical fiber and other optical components that causes a spreading of light pulses as they travel along a fiber, thus degrading the transmission signal.

PRODUCTS OF HIGH QUALITY. Product quality is an integral part of our solution. We have implemented a comprehensive quality assurance program, which has been certified ISO 9001 since 1994. Our products meet industry standards, such as those set by Telcordia, formerly Bellcore, an industry-leading standards body. During manufacturing, each product has a related quality assurance plan, with rigorous checkpoints, to reduce defects to a minimum. More than 40 people are dedicated to various tasks in the quality assurance process including quality control, conformity testing, product documentation, product improvement, regulatory compliance, metrology and calibration.

SUPERIOR CUSTOMER SUPPORT. We use highly qualified and specialized internal groups to offer pre-sales evaluation, installation, channel and customer training, communications and post-sales support. We believe that this approach provides us with an advantage over our competitors, who often outsource some of these functions. Our inside sales group is mainly responsible for supporting our sales force, selecting instruments that best match our customers' testing, measurement and monitoring needs and for providing detailed quotations. Our customer support group manages three main tasks: order processing, technical support and training and calibration and repair services. Furthermore, our communications and marketing group, which operates like an internal advertising agency, educates our customers and our sales force by providing detailed marketing and technical information. Literature includes specification sheets, application notes, media releases, product catalogues and a bi-monthly corporate newsletter. Finally, our writing services group, which consists of more than 15 university-trained professionals, provides technical writing for product instruction manuals and online help. We translate most of our documentation in seven different languages.

OUR STRATEGY

We intend to expand our leadership position in the fiber-optic test, measurement and monitoring industry and to increase our market share through the following initiatives:

EXPAND TECHNOLOGICAL LEADERSHIP. We believe that our ultimate success will depend on our ability to introduce enhanced products that meet the changing needs of our customers. We, therefore, will continue to invest heavily in research and development. We have increased gross research and development expenditures from 11.2% to 15.2% of total sales between the years ended August 31, 1997 and August 31, 1999 and we intend to spend between 12% to 16% of our sales on research and development during the next three years. We also intend to dedicate more than 25% of our employees to research and development, including an advanced research group that carries out research activities, monitors technological trends in the industry and maintains links with numerous universities, industry associations and standards bodies.

We also intend to maintain our profile as experts in the field of fiber-optic test, measurement and monitoring instrumentation through activities such as publishing our DWDM reference guide, a widely distributed reference tool and presenting scientific papers at industry conferences, such as the Optical Fiber Conference and the National Fiber-Optic and Engineering Conference.

INVEST IN STRATEGIC SECTORS. We have established a structured review process to ensure that our research and development activities are aligned with our corporate strategy. This rigorous review process has led us to focus on the following strategic sectors:

- DWDM Market. We recently launched a number of DWDM testing solutions, including optical spectrum analyzers, tunable laser sources and fully automated test systems to capitalize on the DWDM market opportunity. We believe that we are well positioned to take advantage of this growing market because we offer one of the most comprehensive selections of DWDM test products. We intend to further improve our DWDM testing solutions to address the requirements of systems requiring higher channel counts and increased transmission speeds.

- Network Monitoring Market. Carriers have become increasingly concerned about the loss of revenue related to system downtime, especially with the widespread deployment of DWDM networks that concentrate data traffic along fewer fibers. As a result, carriers need to automatically carry out network monitoring in real time to locate faults and degradation points along a network in order to prevent system downtime or shorten restoration time. We have developed our remote fiber test system to address the needs of this market. As carriers' optical networks become more complex, we intend to upgrade our remote fiber test system by providing features like wavelength monitoring, which enables the analysis of power and drift of each wavelength and by supplying improved software for better integration with carriers' existing operational support systems.

- Scientific Product Market. We believe that several new market opportunities exist for our family of scientific products, especially with the increasing reliance of optical component, value-added optical module and optical networking system manufacturers on automated test, measurement and monitoring equipment. We intend to provide manufacturers with both off-the-shelf and customized test solutions. We have established a team of 13 product managers in this division, consisting of engineers and scientists, several of whom hold master's or doctorate degrees in Optical Sciences or Electrical Engineering.

LEVERAGE OUR MODULAR DESIGN. The modularity and compatibility of our Windows-based platforms enable us to offer the same instrument design to as many as three different market segments with a single research and development project. This practice lessens the number of different designs, including optical, mechanical, electronics and software, that we must develop and manufacture. We intend to capitalize on the flexible architecture of our Windows-based systems to expand our solutions portfolio and to offer specialized products to specific markets. By being able to provide new functionality through the design of a new module rather than through the design of a complete instrument, we can be quicker to market with new testing technologies and provide more specialized testing solutions.

40

EXPAND SALES AND MARKETING EFFORTS. We have adopted a focused sales and marketing approach to improve service to existing customers and to pursue new customer opportunities. We intend to:

- expand our direct sales force by opening additional international offices;

- bolster our key account management program by hiring application engineers dedicated to large system manufacturers that are current customers, such as Nortel Networks Corporation, Lucent Technologies, Inc. and Alcatel Optronics;

- increase our network of distributors worldwide;

- open additional service centers in selected, high-growth markets to support our sales activities with calibration and repair services; and

- deploy a customer relationship management software initiative to keep better track of our customers' individual demands and to store information about potential customer opportunities, profiles and histories.

REDUCE DELIVERY LEAD TIMES. The majority of our sales are derived from complex products that are assembled to order. Despite the increased demand for testing, measurement and monitoring instruments, we maintained an average delivery lead time of 30 calendar days for our products during the twelve months ended May 31, 2000. We believe that our delivery lead times are shorter than most of those of our competitors. To further reduce our delivery lead times, we have adopted a number of measures:

- Adhere to Vertically Integrated Manufacturing. We handle all major manufacturing operations in-house because we generally produce short runs of complex products. We believe it is a competitive advantage to have our manufacturing operations centralized since we have greater flexibility and better control over our delivery lead times.

- Increase Manufacturing Capacity. We recently agreed to purchase a building of approximately 112,000 square feet and we intend to make available 60,000 square feet of this additional space for manufacturing. This facility, once equipped, should increase our manufacturing floor space by 167%.

- Implement Enterprise Resource Planning and Supply-Chain Management Software Tools. We intend to improve our information systems environment by implementing enterprise resource planning and supply-chain management software tools. This will enable us to enhance our forecasting, planning and scheduling and procurement activities.

PURSUE COMPLEMENTARY ACQUISITIONS. We believe that market fragmentation in the test, measurement and monitoring industry creates opportunities for consolidation. We plan to pursue strategic acquisitions that will provide us with additional key technologies, complement our product offerings, increase our sales channels and add to our overall level of expertise.

PRODUCTS

Our products are designed for the fiber-optic test, measurement and monitoring industry. We have adapted our product offerings to meet the needs of two main markets: portable and monitoring products for the carrier market and scientific products for the optical component, value-added optical module and optical networking system manufacturer market.

The carrier market primarily encompasses the needs of telecommunications carriers, such as AT&T Corporation, Bell Atlantic Corporation, GTE Corporation and TelMex S.A. de C.V., cable television companies, public utilities, private network operators, as well as third-party network installers and equipment rental companies. This market requires rugged, field-portable and easy-to-use equipment.

The scientific product market includes optical component and value-added optical module companies such as E-Tek Dynamics, Inc. and JDS Uniphase Inc.; optical system manufacturers such as Nortel Networks Corporation and Lucent Technologies, Inc.; optical fiber and cable manufacturers such as Corning Incorporated, Lucent Technologies, Inc. and Sumitomo Electric Lightwave Corp.; as well as university and government research laboratories.

41

At the core of our test, measurement and monitoring instruments are our FTB-300 Universal Test System (UTS) and IQ-200 Optical Test System (OTS) products. Our FTB-300 UTS provides carriers with a simple, yet efficient way to perform multiple, advanced test operations for installation, maintenance and troubleshooting applications. Our IQ-200 OTS is a scalable unit that is suited for manufacturing, laboratory engineering and research applications. The added benefit of our IQ-200 OTS is that manufacturers can design their own automated test setup or we can customize a setup for them. Our FTB-300 UTS and IQ-200 OTS platforms are fully supported by integrated and highly intuitive graphical user interfaces, enabling the user to easily store, handle and retrieve a large amount of data.

At the Optical Fiber Conference in March 2000, we introduced 13 new products, including optical spectrum analyzer test modules for our FTB-300 UTS and IQ-200 OTS platforms, widely tunable laser sources for DWDM testing, automated test systems for DWDM optical components and value-added optical modules, a single-slot optical time domain reflectometer platform and related test modules, as well as high-power and low-polarization sensitivity power meters.

The following table summarizes the principal types of instruments we provide, their typical applications and the format in which we offer them:

Portable and Monitoring Products

We offer an extensive range of products for fiber-optic testing, measurement and monitoring in the carrier market.

Our test and measurement products are available as handheld test instruments modular and field-portable platforms. Our handheld instruments are durable, compact and easy to use. Our portable platforms are rugged, Windows-based, battery-powered units. Their large, environmentally robust touchscreens are very practical for field use.

We recently introduced our remote fiber test system known as FiberVisor. Our FiberVisor consists of rack-mounted remote test units, which are strategically deployed along a fiber-optic network and a test system controller that retrieves information from as many remote test units as required. The test system controller is typically located inside a network operations center. The information obtained from these remote test units is combined with data from a geographic information system in our FiberVisor system to pinpoint the exact location of a system failure and rapidly provide the required information to a restoration team.

Scientific Products

Our scientific product line is mainly built around our IQ-200 OTS platform and is available as modules or stand-alone benchtop instruments. This base platform is a Windows-based system, which includes a Pentium processor, liquid crystal screen and three slots to accept test modules. This base platform can be supplemented by as many as four expansion platforms, each capable of housing six additional modules, which can be connected and controlled to provide additional functionality and capacity. These expansion platforms can also be controlled via a personal computer. Altogether, the IQ-200 OTS platform and expansion platforms can hold as many as 27 modules and test as many as 105 channels.

The modular nature of our IQ-200 OTS platform is adapted for complex applications involving the synchronized operation of several instruments. For example, several types of lasers, a variable attenuator and an optical spectrum analyzer can be combined to automatically characterize a number of key performance parameters of fiber-optic amplifiers.

Our Scientific Division also addresses testing problems that cannot be handled by standard modules or stand-alone benchtop instruments. We have dedicated a team of engineers to develop custom-made, integrated test systems for customers with specific needs. Some of these integrated test systems, in turn, are modified and offered as off-the-shelf test systems to suit a wider range of customers. In addition, we have created a software development kit for developers who prefer writing their own programs for our instruments. We provide automated systems for assembly, calibration and environmental testing for optical components, value-added optical modules and optical networking systems such as:

RESEARCH AND DEVELOPMENT

We believe that our future success largely depends on our ability to maintain and enhance our core technology and product functionality. To keep developing new products and enhancements, it is important that we recruit and retain highly skilled engineers, scientists and technicians. As of May 31, 2000, our research and development department included 185 full-time engineers, scientists and technicians, of whom 36 hold post-graduate degrees. Gross research and development expenditures for fiscal 1999 were $6.4 million and for the last six months ended February 29, 2000, they were $4.7 million.

Through a market-oriented, product portfolio review process, we ensure that our investments in research and development are aligned with our corporate strategy. This approach enables us to maximize our returns on research and development investments by focusing our resources on a limited number of prioritized projects. Quarterly product portfolio review meetings enable us to choose a realistic, balanced mix of new products and allocate the necessary resources for their development. All our projects, including those already underway, are reviewed, given a priority rating and allocated budgets and resources. Our existing projects can be stopped or substantially redefined if there have been significant changes in market conditions, or if the project development schedule or budget has been significantly exceeded.

To manage our research projects once they are underway, we use a structured management process known as the stage-gate approach. The stage-gate approach is based on a systematic review of a project's feasibility at various stages of its life cycle. The following are the key review stages of the stage-gate approach:

- market study and research feasibility;

- product definition;

- development feasibility;

- development;

- qualification; and

- transfer to production.

At each stage, we review our project risks, costs and estimated completion time. We compare our design to anticipated market needs and ensure that our project is synchronized with other internal departments and external industry events.

SALES

We sell our fiber-optic test, measurement and monitoring products through direct and indirect sales networks in the United States and Canada as well as around the world. We also have an inside sales group, consisting of 10 people, to meet the needs of existing and new customers. Our inside sales group is responsible for providing quotations to customers, supporting our sales force and managing more than 2,000 demonstration units.

United States and Canada Sales

In the United States and Canada, our direct sales network consists of a vice-president, four national sales managers and 16 regional sales managers and application engineers, who are located throughout major metropolitan areas. Our main sales office in the United States is located in Richardson, Texas. We also maintain sales personnel in the following metropolitan areas: Atlanta, Georgia; Charlotte, North Carolina; Chicago, Illinois; Columbus, Ohio; Dallas, Texas; Denver, Colorado; Los Angeles, California; Newark, New Jersey; Wilmington, Delaware; Montreal, Quebec; Ottawa, Ontario; Toronto, Ontario; and Vancouver, British Columbia. Our group of 21 sales professionals has an average of 12 years of experience in the fields of telecommunications, fiber optics, or test, measurement and monitoring.

In the United States, we have adopted a market-specific sales strategy. Three different sales organizations have been created to maximize coverage and penetration of our main markets:

- CARRIER MARKET. This sales team targets customers who own, operate or install networks as their primary business. This market includes telecommunications carriers, cable television companies, public utilities, private network operators, as well as third-party installers and equipment rental companies. A national sales manager, seven regional sales managers and a team of independent sales representatives and distributors concentrate on selling our product line to this customer market.

- MANUFACTURING/R&D MARKET. This sales team targets customers who research, develop or manufacture optical networking products. This sales group consists of one national sales manager and seven regional sales managers, who oversee a network of independent sales representatives. Some regional sales managers also have direct responsibility for serving our larger manufacturing customers. This group also includes field application engineers because pre-sales requirements, including the setup of full-scale demonstration units, often require a significant level of technical on-site expertise. The

45

presence of field application engineers enables our regional sales managers to concentrate on other sales and management activities. This organizational structure allows us to adequately cover the demands of a highly technical customer base and to identify and penetrate the large number of start-up companies in the component manufacturer market.

- PRIVATE NETWORK MARKET. We have recently initiated a program to pursue additional business opportunities in this market. We anticipate a growing market with the emergence of Gigabit Ethernet, an advanced transmission protocol used in high-speed local area network applications and other optical technologies that will accelerate the delivery of communications services over optical fiber to the desktop. We recently hired a national sales manager to develop this market for our products through new distributor channels.

International Sales

Our international sales network includes a vice-president, three sales directors covering Europe, Latin America and Asia and eight regional sales managers. Our direct sales network around the world is supported by a main office in Paris, France, which maintains our head European sales operations and also provides repair and calibration services for our European, Middle East and African customers. We also have established several sales offices in strategic locations around the world to support our network of distributors and customers. These offices are located in Brazil, China, Germany, Great Britain, Japan and Singapore. Finally, we rely on more than 50 distributors to support our international sales. We feel that the local presence and cultural attributes of our distributors allow us to better serve our global markets.

MARKETING, COMMUNICATIONS AND CUSTOMER SUPPORT

Marketing

Our marketing group consists of 33 products managers and marketing analysts who have various degrees in engineering, science and business administration. Product managers, with the assistance of marketing analysts, are responsible for all aspects of our marketing program including new product introductions, definition of new features and functions, pricing, product launches and advertising campaigns. Marketing analysts help product managers develop marketing programs with tools such as our Web site, CD-ROMs, advertisements, mailouts and customer presentations. We follow up our marketing initiatives by attending industry trade shows. Furthermore, we are implementing a customer relationship management system to compile market and customer information including forecasts, leads and competitive data. We use this information to make strategic business decisions.

Communications

Our communications group, which is mainly composed of commercial writers and graphic artists, supports our marketing group by producing marketing and corporate documentation. Literature includes specification sheets, application notes, media releases, product catalogues, advertising copy and a bi-monthly corporate newsletter. Our communications group is also responsible for maintaining and updating our Web site.

Customer Support

We have developed a customer support group that serves customers and distributors around the world in English, French, Spanish and German. Our customer support group consists of three distinct units: technical support, customer service and a repair and calibration authorization service center. A frequently asked question database is also updated regularly on our Web site.

MANUFACTURING

Manufacturing operations consist mainly of material planning, procurement, sub-assembly, final assembly, testing, software loading, calibration, quality assurance and shipping and billing. As of May 31, 2000, we had 258 employees involved in our manufacturing operations. We have two surface-mount, circuit-board assembly lines and we occupy more than 36,000 square feet for manufacturing purposes. Upon completion of our purchase of a new facility at 400 Godin Avenue, we will occupy more than 95,000 square feet for manufacturing. Our manufacturing operations are handled by three inter-related departments:

46

- PRODUCTION. Our production department, which is divided into ten cells, is responsible for manufacturing high-quality products on time. Each cell consists of specialized technicians and has full responsibility over a product group. Technicians are versatile enough so that they can perform specific functions within a cell and they can be transferred to other cells when required to alleviate bottlenecks.

- PRODUCTION ENGINEERING AND QUALITY. This department, which supports our production cells, acts like a gatekeeper to ensure the quality of our products and the effectiveness of our manufacturing processes. It is responsible for the transfer of products from research and development to manufacturing, product improvement, documentation, calibration, repairs and the quality assurance and regulatory compliance process. Quality assurance represents a key element in our manufacturing operations. We meticulously verify our instruments to ensure that they meet stringent industry requirements and provide our customers with detailed product test sheets. Our quality assurance program has been certified ISO 9001 since 1994.

- SUPPLY-CHAIN MANAGEMENT. This department is responsible for manufacturing schedules, parts procurement, raw materials and finished goods warehousing, customs management, shipping and billing. Our products consist of optical, electronic and mechanical parts. Approximately one-third of our parts are manufactured to our specifications. Some parts are obtained from single-source suppliers. We manage risks associated with single-source suppliers, as well as parts that are subject to industry shortages or long delivery lead times, through a strategic forecasting process that involves procuring excess inventory where appropriate.

COMPETITION

The fiber-optic test, measurement and monitoring industry is highly competitive and subject to rapid change as a result of technological developments and other factors. We compete with many different companies, depending on product family and geographical market. We believe that the main competitive factors in the industry include the following:

- product performance and reliability;

- level of technological innovation;

- product lead times;

- product offering;

- ease of use;

- customer service and technical support;

- strength of sales and distribution relationships; and

- price.

Generally, our competitors fall into two categories. The first category consists of global electronic test and measurement manufacturers, who complement their broad range of products with fiber-optic test, measurement and monitoring equipment. These companies include Agilent Technologies, Inc., Wavetek Wandel & Golterman, Anritsu Corporation Ando Corporation, Telecommunications Technique Corporation (TTC Dynatec Division), Tektronics, Inc., GN Nettest and Newport Corporation. The second category refers to niche companies in the fiber-optic test, measurement and monitoring industry. These companies typically have limited product lines and are often geographically limited in their customer base. Such companies include Santec Corporation, Photonetics, Inc., Fotec, Inc., ILX Lightwave Corporation and Kingfisher International PTY Ltd. We also face competition from JDS Uniphase Corp., an optical component and value-added optical module vendor that designs and markets its own line of test and measurement instruments.

REGULATORY ENVIRONMENT

In most countries where our products are sold, our products must comply with the regulations of one or more governmental entities. These regulations often are complex and vary from country to country. Depending upon the country and the relevant product, the applicable regulations may require product testing, approval,

47

registration, marking and unique design restrictions. Accordingly, we have appointed a team of engineers who are responsible for ensuring that our products comply with all applicable regulations.

In the United States, our products must comply with the regulations of several agencies of the U.S. federal government, including the Federal Communications Commission, or the FCC, the Food and Drug Administration, or the FDA and the Occupational Safety and Health Administration, or OSHA. Under the FCC's regulations, our products must comply with, among other things, rules concerning unintentional radio frequency emissions that interfere with protected radio communications systems. Depending upon the product, compliance with these rules may necessitate applying for and obtaining an FCC equipment authorization prior to importing into the United States, or marketing, any units of the relevant product. Additionally, some of our products must comply with the FDA's performance standards and related rules concerning light-emitting products, such as lasers. The FDA's regulations are intended to promote safety by limiting human exposure to harmful electromagnetic radiation. Similarly, our products must comply with OSHA's design safety standards for systems that utilize electricity. These rules are intended to reduce the risk of accidental human electrocution.

Similar regulations apply in other countries. For example, our products are subject to the safety standards of Industry Canada and the Canadian Standards Association with respect to electricity utilization and radio frequency emissions. Other countries in the world require equipment marking in accordance with the standards of the European Community, often referred to as CE marking, testing to ensure compliance with International Electrotechnical Commission standards and other international product approval. Other significant types of regulations not described in this prospectus also may apply, depending upon the relevant product and country.

INTELLECTUAL PROPERTY

Our success and ability to compete are dependent in part on our ability to develop and protect our proprietary technology. We file U.S. and Canadian patent applications to protect technology, inventions and improvements important to the development of our business. We also rely on a combination of copyright, trademark, trade secret rights, licensing and confidentiality agreements.

We currently hold four U.S.-issued, two Canadian-issued and three foreign-issued patents and we have six U.S. and eight Canadian patent applications pending. These issued and pending patents cover various aspects of our products and processes. The expiration dates of our issued patents range from July 17, 2011 to October 9, 2016.

We consider three of our inventions for which patents have either been granted or are pending to be material. These inventions are:

- the optical time domain reflectometer with internal reference reflector for which a patent was granted in the United States and is pending in Canada. This invention permits the control of the optical time domain reflectometer detector gain and the determination of the loss of the initial optical connector and is used in most of our optical time domain reflectometer-based products;

- the measurement of attenuation of optical fibers using bidirectional transmission of information via the fiber for which patents were granted in the United States and Canada. This invention forms the basis of our FOT-920 and FTB-3920 products; and

- an adapter for interconnecting optical fiber connectors for which patents are pending in Canada and the United States. This invention permits a wide variety of connectors to be joined to our test and measurement instruments.

Confidentiality and proprietary information agreements with our senior management, employees and others generally stipulate that all confidential information developed or made known to these individuals by us during the course of their relationship is to be kept confidential and not disclosed to third parties, except in specific circumstances. The agreements also generally provide that all intellectual property developed by the individual in the course of rendering services to us belongs exclusively to us. These efforts afford only limited protection.

We have entered into an agreement to purchase the building located at 400 Godin Avenue in Vanier, Quebec, for a consideration of C$4.9 million (approximately $3.3 million). This transaction is expected to close in June 2000. In addition to the 25,118 square feet that we lease, this transaction will progressively make available approximately 87,000 square feet to be used for manufacturing and research and development. With the additional space, we believe that the existing facilities will be adequate to meet our current needs. However, as we continue to experience growth, additional space will be required by mid to late 2001.

EMPLOYEES

We have fostered a corporate culture where growth and change are strongly encouraged. In fact, employees are constantly evolving with the rapid pace of technology to meet new challenges and realities. We believe that we possess a good cross-section of experience and youth to handle these inevitable changes in the industry. The average age of our employees is around 30 years old. Over the years, we have benefited from our proximity to Laval University, which is located near Quebec City. Laval University has post-graduate programs in optical and electronic engineering.

As of May 31, 2000, we employed 671 full-time employees who originate from approximately 20 countries. 185 are involved in research and development, 258 in manufacturing, 93 in sales and marketing, 77 in general administrative positions and 58 in communications and customer support. During the last 12 months, we added more than 240 employees. We have agreements with the majority of our employees covering confidentiality and non-competition. Only manufacturing employees are represented by a collective bargaining agreement, which expires in 2004. We have never experienced a work stoppage. We believe that relations with our employees are good.

LEGAL PROCEEDINGS

We are not a party to any material legal proceedings, nor are we aware of any such legal proceedings that are contemplated.

EMPLOYMENT AGREEMENT

We will, prior to the closing of this offering, enter into an employment agreement with Germain Lamonde. The agreement will provide for Mr. Lamonde's employment as our President and Chief Executive Officer at a base salary, without adjustment, during the time between the signing of the agreement and August 31, 2000 of C$275,000 per year. Mr. Lamonde shall also be entitled to receive, during the period from September 1, 2000 to August 31, 2001, a base salary of C$275,000 plus a variable portion based on a formula established by our board of directors.

In the event of the termination of Mr. Lamonde's employment with us, other than for cause, Mr. Lamonde will be entitled to severance payments (in no case exceeding 24 months of remuneration) and the vesting of all stock options, upon the incapacity of Mr. Lamonde, a merger, acquisition by a third party of substantially all of our assets or of the majority of our share capital or termination of Mr. Lamonde without cause by us.

STOCK OPTION PLAN

We will, prior to the closing of this offering and subject to regulatory approval, establish a stock option plan for our directors, executive officers, employees and consultants and those of our subsidiaries as determined by

54

our board of directors, to attract and retain competent directors, executive officers, employees and consultants motivated to work toward ensuring our success and to encourage them to acquire our shares.

All of the options that will be granted under the plan may be exercised within a maximum period of ten years following the grant date of the options. The board of directors will designate the recipients of options and determine the number of subordinate voting shares covered by each of these options, the date of vesting of each option, the exercise price of each option, the expiry date and any other conditions relating to these options, in each case in accordance with the applicable legislation of the securities regulatory authorities. The price at which the subordinate voting shares may be purchased under the plan will not be lower than the highest of the closing prices of the subordinate voting shares on the stock exchanges where the subordinate voting shares are listed at the date of grant.

The maximum number of subordinate voting shares that is issuable under the plan may not exceed 4,470,961 shares. The maximum number of subordinate voting shares that may be granted to any individual may not exceed 5% of the outstanding subordinate voting shares. The board of directors may accelerate the vesting of any or all outstanding options of any or all optionees upon the occurrence of a change of control.

Prior to the closing of this offering, we intend to grant to 554 of our employees and to all directors who are not officers or employees options to purchase a total of 581,280 subordinate voting shares at the initial public offering price with a vesting period of up to five years following the date of the grant. Following this grant, there will be 3,889,681 options that are available for future grants under the plan.

SHARE PLAN

In September 1998, we established a stock purchase plan for officers, directors and key employees as amended in April 2000. As of June 7, 2000, 709,605 Class "F" shares had been issued and fully paid under the 1998 Stock Purchase Plan. Prior to the closing of this offering, a total of 709,605 Class "F" shares will have been issued pursuant to the 1998 Stock Purchase Plan for a weighted average cash consideration of C$0.99 per share. The plan provides that all shares issued under the plan are restricted as to sale and transferability for a minimum period of five years upon the date of acquisition. Prior to the closing of this offering, all of the 709,605 Class "F" shares will be converted into subordinate voting shares.

On April 3, 2000, we adopted a new share plan which replaced the 1998 Stock Purchase Plan. No additional shares will be issued under the new share plan. The new share plan established restrictions on the rights of the holders of subordinate voting shares who hold those shares as a result of the conversion of the Class "F" shares issued under the 1998 Stock Purchase Plan. The new share plan also requires the subordinate voting shares to be held in trust by a trustee until August 31, 2004, except for 256,017 subordinate voting shares which will be released between October 21, 2003 and January 20, 2004. The new share plan also provides for the earlier release of shares in the event that the employment of a holder of shares is terminated or upon the occurrence of a change of control. The new share plan does not permit any transfer, except within the trust to a registered retirement savings plan or a registered retirement income fund or to a trustee in bankruptcy. The new share plan also established the conditions pursuant to which the shares of a shareholder are to be sold by the trustee on the public market.

DEFERRED PROFIT SHARING PLAN

Under the plan, we contribute an amount equal to 1% of each employee's gross salary to that employee's individual deferred profit sharing plan to the extent that such employee contributes at least 2% of his or her gross salary to his or her individual tax-deferred registered retirement savings plan. We may also make discretionary contributions of up to 4% of an employee's gross salary to his or her individual tax deferred registered retirement savings plan, depending on our and the employee's performance. In the year ended August 31, 1999, the aggregate amount of contributions under the plan was $104,000 (C$156,000).

55

401(K) PLAN OF EXFO AMERICA INC.

We maintain a 401(k) plan to provide employees of EXFO America Inc. who are residents of the United States, with a tax preferential savings and investment program. Employees become eligible to participate in the 401(k) plan on the first day of the month following the completion of three months of continuous service. Employees may elect to defer their current compensation up to the lesser of 1% of eligible compensation or the statutorily prescribed annual limit and have the deferral contributed to the 401(k) plan. The 401(k) plan permits, but does not require, us to make additional matching contributions to the 401(k) plan on behalf of the eligible participants, subject to a maximum of 50% of the first 6% of the participant's current compensation. The contributions made by and on behalf of employees may not exceed the maximum contribution limitation currently equal to the lesser of 15% of their compensation or $10,500 per year under current statutory limitations. In the year ended August 31, 1999, we made an aggregate of $21,000 in matching contributions to the 401(k) plan. Contributions by employees or by us to the 401(k) plan and income earned on plan contributions are generally not taxable to the employees until withdrawn and contributions by us are generally deductible by us when made. At the direction of each participant, the trustee of the 401(k) plan invests the assets of the 401(k) plan in selected investment options.

INDEMNIFICATION OF DIRECTORS AND EXECUTIVE OFFICERS AND LIMITATION OF LIABILITY

Our by-laws require us, subject to the limitations provided by law, to indemnify our present or former directors and officers or any persons who act or acted at our request as directors or officers of a body corporate of which we are or were a shareholder and for all costs, losses, charges and expenses that arose or may arise by reason of their status as directors or officers of EXFO or such body corporate. A policy of directors' and officers' liability insurance is maintained by us which insures our directors and officers and those of our subsidiaries against liability incurred by, arising from or against them for certain of their acts, errors or omissions.

INDEBTEDNESS OF DIRECTORS, EXECUTIVE OFFICERS AND EMPLOYEES

We have guaranteed the repayment of loans granted to employees by a financial institution for the purchase of our Class "F" shares that will be converted into subordinate voting shares prior to the closing of this offering. As of June 7, 2000, the total principal amount guaranteed by us is C$243,599 (approximately $165,000). We loaned to some of our employees up to $26,000 to finance the acquisition of our Class "F" shares. These loans are to be reimbursed no later than five years from the date of the loans. These loans will accrue interest at prime rate and will be secured by a pledge of the employees' shares to us.

TRANSACTIONS WITH RELATED PARTIES

Except as disclosed in this section, none of our directors, executive officers, associates or affiliates had any material interest in any transaction with us during the past three years or in any proposed transaction which has materially affected or could materially affect us.

LEASES

We have entered into lease agreements with 9080-9823 Quebec inc., a company controlled by Mr. Germain Lamonde, for the manufacturing facilities located at 436 Nolin Street and the executive and administrative offices located at 465 Godin Avenue in Vanier, Quebec. The table below sets forth the leased space, annual rent and term of the leases:

LOCATION               SQUARE FOOTAGE   ANNUAL RENT      EXPIRY DATE
--------               --------------   -----------   -----------------
436 Nolin                  44,164        C$220,820    February 28, 2001
465 Godin                  24,000        C$144,000    November 30, 2001

Based on third-party valuations of the property values, we believe these lease agreements are at prevailing market terms.

Immediately prior to this offering, we will modify our authorized share capital to:

- the 709,605 Class "F" shares will be exchanged into 709,605 subordinate voting shares; and

- the 800,000 Class "G" shares will be exchanged into 800,000 preferred shares series 1.

EQUITY SHARES

Except as otherwise described, the equity shares, which means the multiple voting shares and the subordinate voting shares, have the same rights, are equal in every respect and are treated as if they were shares of one and the same class.

Rank

The equity shares rank junior to the preferred shares in the payment of dividends, return of capital and distribution of assets in the event of liquidation, dissolution or any distribution of our assets for the purpose of winding up our affairs.

Dividends

The holders of outstanding equity shares may receive dividends on a share-for-share basis, in the amounts and at the times our board of directors may determine, out of our assets legally available for this purpose, without preference or distinction among or between the multiple voting shares and the subordinate voting shares.

Voting Rights

The subordinate voting shares carry one vote per share and the multiple voting shares carry ten votes per share. The holders of equity shares are entitled to receive notice of any meeting of our shareholders and to attend and vote as a single class on all matters to be voted on by our shareholders, except at meetings where the holders of shares of one class or of a particular series of shares are entitled to vote separately.

Modification

The rights, privileges, conditions and restrictions attaching to the equity shares may be modified if the amendment is authorized by at least two-thirds of the votes cast at a meeting of the holders of equity shares duly held for that purpose. However, if the holders of subordinate voting shares, as a class, or the holders of multiple voting shares, as a class, are to be affected in a manner different from the other classes of shares, the amendment must, in addition, be authorized by at least two-thirds of the votes cast at a meeting of the holders of the class of shares which is affected differently.

60

Additional Issuance of Multiple Voting Shares

We may not issue multiple voting shares without the approval of at least two-thirds of the votes cast at a meeting of the holders of subordinate voting shares duly held for that purpose. However, approval is not required in connection with a subdivision on a pro rata basis as between the subordinate voting shares and the multiple voting shares.

Conversion

Each outstanding multiple voting share may, at any time, at the option of the holder, be converted into one subordinate voting share. The subordinate voting shares cannot be converted into any other class of shares.

Subdivision or Consolidation

No subdivision or consolidation of the multiple voting shares or the subordinate voting shares will be made without, concurrently, having the multiple voting shares or subordinate voting shares, as the case may be, subdivided or consolidated under the same conditions.

Liquidation Rights and Other Matters

The equity shares are not redeemable by us or by the holder. Upon the liquidation, dissolution or any distribution of our assets for the purpose of winding up our affairs, the holders of equity shares are entitled to participate equally, on a share-for-share basis, in our remaining property and assets available for distribution to the holders of equity shares.

Undertakings in Favor of Holders of Subordinate Voting Shares

Under applicable Canadian law, an offer to purchase multiple voting shares would not necessarily require that an offer be made to purchase subordinate voting shares. In accordance with the rules of The Toronto Stock Exchange, we and each of Germain Lamonde, GEXFO Investissements Technologiques inc., Fiducie Germain Lamonde and G. Lamonde Investissements Financiers inc., as the beneficial and registered owners of all the outstanding multiple voting shares will enter into a trust agreement prior to the closing of this offering with a third party trustee. Under the trust agreement, Germain Lamonde, GEXFO Investissements Technologiques inc., Fiducie Germain Lamonde and G. Lamonde Investissements Financiers inc. will place their multiple voting shares on deposit with the trustee and undertake not to sell or dispose of, directly or indirectly, any multiple voting shares pursuant to a take-over bid, as defined by applicable securities legislation, under circumstances in which securities legislation would have required the same offer or a follow-up offer to be made to all holders of subordinate voting shares if the sale had been of subordinate voting shares rather than multiple voting shares, but otherwise on the same terms. This undertaking does not apply if:

- such sale is made pursuant to an offer to purchase only part of the multiple voting shares made to Germain Lamonde, GEXFO Investissements Technologiques inc., Fiducie Germain Lamonde and G. Lamonde Investissements Financiers inc. and an offer, with terms at least as favourable as the terms of the offer to purchase multiple voting shares, is made concurrently to all holders of subordinate voting shares to purchase the same proportionate number of subordinate voting shares at a price per share at least as high as the highest price per share offered in connection with the sale or disposition of the multiple voting shares, which offer has no condition attached other than the right not to take up and pay for the subordinate voting shares tendered if no shares are purchased pursuant to the offer for multiple voting shares; or

- there is a concurrent unconditional offer, with terms at least as favourable as the terms of the offer to purchase multiple voting shares, to purchase all the subordinate voting shares at a price per share at least as high as the highest price per share offered in connection with the sale or disposition of the multiple voting shares.

61

The trust agreement permits, subject to the prior consent of the trustee as provided for below, certain direct and indirect sales if:

- the sale or disposition is effected within the Lamonde Family at a price which is not over 15% from the average market price established with the formula prescribed by the Securities Act (Quebec);

- the sale or disposition is effected within the Lamonde Family and the transferee is not a party to any agreement under which any other person would participate in the beneficial ownership of, control or direction over more than 50% of the votes attaching to the equity shares held by such transferee; and

- the transferee, if not already a party to the trust agreement, becomes a party to such trust agreement.

The term "Lamonde Family" means:

- Germain Lamonde;

- his spouse, in fact or in law;

- any lineal descendant of Germain Lamonde, born or to be born;

- any trust constituted primarily for the benefit of Germain Lamonde, his spouse, in fact or in law, or any of his descendants, born or to be born; and

- any corporation where 90% of the votes attaching to all outstanding shares and at least 50% of all outstanding shares are controlled by any one or more of the persons listed above;

Under the trust agreement, any direct or indirect sale or disposition of multiple voting shares, including a transfer to a pledgee as security, by a party bound by its terms or any person or corporation which it controls is conditional upon the transferee becoming a party to an agreement on substantially similar terms and conditions as are contained in the trust agreement. The conversion of multiple voting shares into subordinate voting shares shall not constitute a sale or disposition for purposes of the trust agreement.

The trust agreement provides that if a person or corporation carries out an indirect sale or a disposition in respect of any multiple voting shares in contravention of the trust agreement, then no person shall from the time such sale becomes effective and thereafter:

- directly or indirectly sell or dispose of any of such multiple voting shares or convert them into subordinate voting shares, in either case, without the prior written consent of the trustee; or

- exercise any voting rights attaching to such multiple voting shares except in accordance with the written instructions of the trustee.

The trustee may attach conditions to its consent and must exercise its rights in the best interest of the holders of the subordinate voting shares, other than Germain Lamonde, GEXFO Investissements Technologiques inc., Fiducie Germain Lamonde and G. Lamonde Investissements Financiers inc. and holders of multiple voting shares who, in the opinion of the trustee, participated directly or indirectly in the transaction that triggered the operation of this provision.

The trust agreement provides that the prior written consent of the trustee shall be required in connection with any sale or disposition of multiple voting shares, whether direct or indirect, by Germain Lamonde, GEXFO Investissements Technologiques inc., Fiducie Germain Lamonde and G. Lamonde Investissements Financiers inc. The trustee must give its written consent if it receives evidence satisfactory to it that the sale or disposition is not in contravention of the trust agreement. The trustee also has the right to require from time to time satisfactory evidence to it of the number of equity shares held directly or indirectly by Germain Lamonde, GEXFO Investissements Technologiques inc., Fiducie Germain Lamonde and G. Lamonde Investissements Financiers inc.

The trust agreement contains provisions for the authorization of action by the trustee to enforce the rights under the agreement on behalf of the holders of the subordinate voting shares. The obligation of the trustee to take such action is conditional on the provision of required funds and indemnity by us or holders of subordinate voting shares. No holder of the subordinate voting shares will have the right, other than through the trustee, to institute any action or proceeding or to exercise any other remedy to enforce any rights arising under the trust

62

agreement unless the trustee fails to act on a request authorized by holders of not less than 10% of the outstanding subordinate voting shares, excluding any subordinate voting shares beneficially held by the Germain Lamonde, GEXFO Investissements Technologiques inc., Fiducie Germain Lamonde and G. Lamonde Investissements Financiers inc. or any holders of multiple voting shares, after provision of reasonable funds and indemnity to the trustee.

The trust agreement provides that it may not be amended and no provision thereof may be waived, without the approval of:

- any Canadian stock exchange upon which the subordinate voting shares are quoted or listed and any other applicable securities regulatory authorities; and

- at least two-thirds of the votes cast by holders of subordinate voting shares.

No provision of the trust agreement limits the rights of any holders of subordinate voting shares under applicable securities legislation.

Mandatory Conversion

The trust agreement also provides that, except as otherwise provided, if at any time:

- members of the Lamonde Family do not beneficially own, directly or indirectly, in any manner, a number of equity shares representing either more than 50% of the votes attaching to all issued and outstanding equity shares or 60% of the total number of multiple voting shares held by them on the closing of this offering (or 22,800,000 multiple voting shares); or

- Germain Lamonde no longer occupies the position of either our Chairman of the Board or our Chief Executive Officer for any reason, including voluntary or forced retirement, death or incapacity,

then all our the multiple voting shares shall be automatically converted into subordinate voting shares, unless such situation is remedied within 60 days from its occurrence or within one year from the occurrence, if such occurrence results from the incapacity of Germain Lamonde. Moreover, if at any time, the Lamonde Family or any of its members sells or otherwise transfers multiple voting shares to a party who is not a member of the Lamonde Family, the transferred shares shall automatically be converted into subordinate voting shares on the date of such sale or transfer.

PREFERRED SHARES

Our board of directors may from time to time issue one or more series of preferred shares. The preferred shares will rank prior to the equity shares with respect to the payment of dividends and the distribution of assets. In the event of our dissolution, the distribution of our assets upon our liquidation or the distribution of all or part of our assets among our shareholders, holders of preferred shares will be entitled to receive, in cash or in property, an amount equal to the value of the consideration paid in respect of the outstanding preferred shares, plus an amount equal to accrued and unpaid dividends, or declared and unpaid dividends and any amount specified in our articles.

PREFERRED SHARES SERIES 1

In addition to the provisions attaching to the preferred shares as a class, the 800,000 preferred shares series 1 have specific provisions applicable to them. We are required to redeem all outstanding preferred shares series 1 on November 30, 2000, by paying to the holders of the preferred shares series 1 a cash payment of C$1.00 per share. We have the option to convert all of such shares into subordinate voting shares on November 30, 2000. The number of subordinate voting shares resulting from such conversion shall be equal to the result obtained by dividing the aggregate redemption price of the preferred shares series 1, being the number of preferred shares series 1 outstanding multiplied by C$1.00 by the conversion price equal to (1) the average closing prices of the subordinate voting shares for the 10 days of market activity preceding November 30, 2000; or (2) if the subordinate voting shares have been traded fewer than 5 days of the 10 days of market activity preceding November 30, 2000, the conversion price is obtained by averaging the closing price or if the closing

63

price is not published, the average between the highest and the lowest prices, for each day that there has been trading and the average of the bid and ask prices for each day on which there was no trading. The conversion price will be determined by reference to the market on which the greatest volume of trading of the subordinate voting shares occurred during the 10 day period. Subject to the provisions of the Canada Business Corporation Act, the preferred shares series 1 will not carry any voting rights.

MODIFICATIONS, SUBDIVISIONS AND CONSOLIDATIONS

Under the Canada Business Corporations Act, amendment of the rights of holders of a class of shares, including subordinate voting shares, requires the approval of not less than two-thirds of the votes cast by the holders of those shares voting separately as a class at a special meeting. The Canada Business Corporations Act also gives these holders the right to dissent from the amendment and to require us to pay them the fair value of their shares.

OWNERSHIP RESTRICTIONS

There is no law or governmental decree or regulation in Canada that restricts the export or import of capital, or affects the remittance of dividends, interest or other payments to non-resident holders of our subordinate voting shares, other than withholding tax requirements.

There is no limitation imposed by Canadian law or by our articles of incorporation or our other charter documents on the right of a non-resident to hold or vote subordinate voting shares, other than as provided by the Investment Canada Act, the North American Free Trade Agreement Implementation Act (Canada) and the World Trade Organization Agreement Implementation Act. The Investment Canada Act requires notification and, in certain cases, advance review and approval by the Government of Canada of the acquisition by a "non-Canadian" of "control" of a "Canadian business", all as defined in the Investment Canada Act. Generally, the threshold for review will be higher in monetary terms for a member of the World Trade Organization or North American Free Trade Agreement.

TRANSFER AGENT AND REGISTRAR

The transfer agent and registrar for the subordinate voting shares in Canada is CIBC Mellon Trust Company, at its principal offices in Montreal, Toronto and Vancouver and in the United States is ChaseMellon Shareholder Services, L.L.C., at its principal office in New York.

SHARES ELIGIBLE FOR FUTURE SALE

The sale of substantial numbers of subordinate voting shares in the public market, or the possibility of this sale, could adversely affect prevailing market prices for our subordinate voting shares.

Upon completion of this offering:

- 6,709,605 of subordinate voting shares will be outstanding;

- 38,000,000 multiple voting shares convertible into 38,000,000 subordinate voting shares will be outstanding;

- 800,000 preferred shares series 1 convertible into 25,766 subordinate voting shares, assuming a conversion price of $21.00 per share, will be outstanding; and

- 4,470,961 subordinate voting shares will be issuable under our stock option plan, including 581,280 subordinate voting shares to be issued upon the exercise of the options to be granted to employees prior to the closing of this offering at an exercise price equal to the initial public offering price.

All of the subordinate voting shares sold in this offering in the United States and Canada will be freely tradeable without restriction under either the U.S. Securities Act, except by "affiliates" as defined in Rule 144

64

under the U.S. Securities Act, or applicable Canadian securities laws, except by "control persons" as defined under these laws.

Each of our officers, directors and shareholders have agreed that they will not dispose of or hedge any of their shares for at least 180 days following the date of this prospectus.

CANADIAN RESALE RESTRICTIONS

Under applicable Canadian securities laws, all of the subordinate voting shares outstanding immediately prior to this offering and all subordinate voting shares issuable upon the conversion of all other classes of shares outstanding and resulting from the conversion of the preferred shares series 1, outstanding immediately prior to this offering and the subordinate voting shares resulting from the exercise of options granted prior to this offering held by Canadian residents may not be sold or otherwise disposed of for value in Canada, except through or with a prospectus, a discretionary exemption or a statutory exemption available only in specific limited circumstances or until we have been a reporting issuer for the prescribed period of time, as applicable, and disclosure to applicable Canadian securities regulatory authorities has been made. We will become a reporting issuer in all the provinces of Canada when we file this prospectus with the securities regulatory authorities of those provinces and when those authorities issue receipts for the prospectus. We expect that the receipts will be issued on or about the date of this prospectus. We are applying to the applicable regulatory authorities for a discretionary exemption to permit the resale of shares without a prospectus required. In addition, sales of our subordinate voting shares in Canada by our majority shareholder will also be restricted.

U.S. RESALE RESTRICTIONS

In general, under Rule 144, as in effect on the date of this prospectus, any person, including our affiliates, who has beneficially owned subordinate voting shares for at least one year will be entitled to sell, in any three- month period, a number of shares that (together with subordinate voting shares with which the person's shares must be aggregated) does not exceed the greater of:

- 1% of the then outstanding subordinate voting shares; and

- the average weekly trading volume of the subordinate voting shares on the Nasdaq National Market during the four calendar weeks immediately preceding the filing of a Form 144 with respect to the sale.

Sales of restricted securities under Rule 144 must also satisfy requirements relating to manner of sale, notice and availability of current public information about us. Our affiliates must also comply with the restrictions and requirements of Rule 144, other than the one-year holding period requirement, in order to sell subordinate voting shares which are not restricted securities.

We intend to file with the SEC a registration statement on Form S-8 within approximately 180 days after the date of this prospectus. The S-8 registration statement will allow holders of subordinate voting shares who are residents of the United States and countries other than Canada to resell subordinate voting shares issued under equity incentive arrangements and subordinate voting shares issued in connection with option exercises.

OTHER RESALE RESTRICTIONS

Of the 709,605 subordinate voting shares issued to our employees under the 1998 Stock Purchase Plan, 256,017 subordinate voting shares will be held in trust and restricted from resale until dates ranging from October 21, 2003 to January 20, 2004 and the balance will be held in trust and restricted from resale until August 31, 2004. See "Management -- Share Plan."

TAX CONSIDERATIONS

UNITED STATES TAXATION

In the opinion of Paul, Weiss, Rifkind, Wharton & Garrison, the information set forth below under the caption "United States Taxation" is a summary of the material U.S. federal income tax consequences of the acquisition, ownership and disposition of subordinate voting shares by a U.S. Holder, as defined below. These discussions are not a complete analysis or listing of all of the possible tax consequences of such transactions and do not address all tax considerations that may be relevant to particular holders in light of their personal circumstances or to persons that are subject to special tax rules. In particular, the information set forth under the caption "United States Taxation" deals only with U.S. Holders that will hold subordinate voting shares as capital assets within the meaning of the Internal Revenue Code of 1986, as amended, and who do not at any time own individually, nor are treated as owning 10% or more of the total combined voting power of all classes of our stock entitled to vote. In addition, this description of U.S. tax consequences does not address the tax treatment of special classes of U.S. Holders, such as banks, tax-exempt entities, insurance companies, persons holding subordinate voting shares as part of a hedging or conversion transaction or as part of a "straddle," U.S. expatriates, persons subject to the alternative minimum tax, dealers or traders in securities or currencies and holders whose "functional currency" is not the U.S. dollar. This summary does not address estate and gift tax consequences or tax consequences under any foreign, state or local laws other than as provided in the section entitled "Canadian Federal Income Tax Considerations" provided below.

As used in this section, the term "U.S. Holder" means:

(a) an individual citizen or resident of the United States;

(b) a corporation created or organized under the laws of the United States or any state thereof including the District of Columbia;

(c) an estate the income of which is subject to United States federal income taxation regardless of its source;

(d) a trust if a court within the United States is able to exercise primary jurisdiction over its administration and one or more U.S. persons have authority to control all substantial decisions of the trust; or

(e) a partnership to the extent the interests therein are owned by any of the persons described in clauses (a), (b), (c) or (d) above.

Holders of subordinate voting shares who are not U.S. Holders, sometimes referred to as "Non-U.S. Holders", should also consult their own tax advisors, particularly as to the applicability of any tax treaty.

The following discussion is based upon:

- the Internal Revenue Code;

- U.S. judicial decisions;

- administrative pronouncements;

- existing and proposed Treasury regulations; and

- the Canada -- U.S. Income Tax Treaty.

Any of the above is subject to change, possibly with retroactive effect. We have not requested, and will not request, a ruling from the U.S. Internal Revenue Service with respect to any of the U.S. federal income tax consequences described below, and as a result, there can be no assurance that the U.S. Internal Revenue Service will not disagree with or challenge any of the conclusions we have reached and describe here.

POTENTIAL PURCHASERS ARE URGED TO CONSULT THEIR TAX ADVISORS AS TO THE PARTICULAR CONSEQUENCES TO THEM UNDER U.S. FEDERAL, STATE, LOCAL AND APPLICABLE FOREIGN TAX LAWS OF THE ACQUISITION, OWNERSHIP AND DISPOSITION OF SUBORDINATE VOTING SHARES.

66

Dividends

Subject to the discussion of passive foreign investment companies below, the gross amount of any distribution paid by us to a U.S. Holder will generally be subject to U.S. federal income tax as foreign source dividend income to the extent paid out of our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. The amount of any distribution of property other than cash will be the fair market value of such property on the date of the distribution. Dividends received by a U.S. Holder will not be eligible for the dividends received deduction allowed to corporations. To the extent that an amount received by a U.S. Holder exceeds such holder's allocable share of our current and accumulated earnings and profits, such excess will be applied first to reduce such U.S. Holder's tax basis in his subordinate voting shares, thereby increasing the amount of gain or decreasing the amount of loss recognized on a subsequent disposition of the subordinate voting shares. Then, to the extent such distribution exceeds such U.S. Holder's tax basis, it will be treated as capital gain. We do not currently maintain calculations of our earnings and profits for U.S. federal income tax purposes.

The gross amount of distributions paid in Canadian dollars, or any successor or other foreign currency, will be included in the income of such U.S. Holder in a dollar amount calculated by reference to the spot exchange rate in effect on the day the distributions are paid regardless of whether the payment is in fact converted into U.S. dollars. If the Canadian dollars, or any successor or other foreign currency, are converted into U.S. dollars on the date of the payment, the U.S. Holder should not be required to recognize any foreign currency gain or loss with respect to the receipt of Canadian dollars as distributions. If, instead, the Canadian dollars are converted at a later date, any currency gains or losses resulting from the conversion of the Canadian dollars will be treated as U.S. source ordinary income or loss. Any amounts recognized as dividends will generally constitute foreign source "passive income" or, in the case of certain U.S. Holders, "financial services income" for U.S. foreign tax credit purposes. A U.S. Holder will have a basis in any Canadian dollars distributed equal to their dollar value on the payment date.

A Non-U.S. Holder of subordinate voting shares generally will not be subject to U.S. federal income or withholding tax on dividends received on subordinate voting shares unless such income is effectively connected with the conduct by such Non-U.S. Holder of a trade or business in the United States.

Sale or Exchange

A U.S. Holder's initial tax basis in the subordinate voting shares will generally be cost to the holder. A U.S. Holder's adjusted tax basis in the subordinate voting shares will generally be the same as cost, but may differ for various reasons including the receipt by such holder of a distribution that was not made up wholly of earnings and profits as described above under the heading "Dividends." Subject to the discussion of passive foreign investment companies below, gain or loss realized by a U.S. Holder on the sale or other disposition of subordinate voting shares will be subject to U.S. federal income taxation as capital gain or loss in an amount equal to the difference between the U.S. Holder's adjusted tax basis in the subordinate voting shares and the amount realized on the disposition. In the case of a non-corporate U.S. Holder, the federal tax rate applicable to capital gains will depend upon:

- the holder's holding period for the subordinate voting shares, with a preferential rate available for subordinate voting shares held for more than one year; and

- the holder's marginal tax rate for ordinary income.

Any gain realized will generally be treated as U.S. source gain and loss realized by a U.S. Holder generally also will be treated as from sources within the United States.

The ability of a U.S. Holder to utilize foreign taxes as a credit to offset U.S. taxes is subject to complex limitations and conditions. The consequences of the separate limitation calculation will depend upon the nature and sources of each U.S. Holder's income and the deductions allocable thereto. Alternatively, a U.S. Holder may elect to claim all foreign taxes paid as an itemized deduction in lieu of claiming a foreign tax credit. A deduction does not reduce U.S. tax on a dollar-for-dollar basis like a tax credit, but the availability of the deduction is not subject to the same conditions and limitations applicable to foreign tax credits.

67

If a U.S. Holder receives any foreign currency on the sale of subordinate voting shares, such U.S. Holder may recognize ordinary income or loss as a result of currency fluctuations between the date of the sale of subordinate voting shares and the date the sale proceeds are converted into U.S. dollars.

A Non-U.S. Holder of subordinate voting shares generally will not be subject to U.S. federal income or withholding tax on any gain realized on the sale or exchange of such subordinate voting shares unless:

- such gain is effectively connected with the conduct by such Non-U.S. Holder of a trade or business in the United States; or

- in the case of any gain realized by an individual Non-U.S. Holder, such Non-U.S. Holder is present in the United States for 183 days or more in the taxable year of such sale and certain other conditions are met.

Personal Holding Company

We could be classified as a personal holding company for U.S. federal income tax purposes if both of the following tests are satisfied:

- if at any time during the last half of our taxable year, five or fewer individuals own or are deemed to own more than 50% of the total value of our shares; and

- we receive 60% or more of our U.S. related gross income from specified passive sources, such as royalty payments.

A personal holding company is taxed on a portion of its undistributed U.S. source income, including specific types of foreign source income which are connected with the conduct of a U.S. trade or business, to the extent this income is not distributed to shareholders. We do not believe we are a personal holding company presently and we do not expect to become one. However, we can not assure you that we will not qualify as a personal holding company in the future.

Foreign Personal Holding Company

We could be classified as a foreign personal holding company if in any taxable year both of the following tests are satisfied:

- five or fewer individuals who are United States citizens or residents own or are deemed to own more than 50% of the total voting power of all classes of our shares entitled to vote or the total value of our shares; and

- at least 60%, 50% in some cases, of our gross income, as adjusted, consists of "foreign personal holding company income", which generally includes passive income such as dividends, interests, gains from the sale or exchange of shares or securities, rent and royalties.

If we are classified as a foreign personal holding company and if you hold shares in us, you may have to include in your gross income as a dividend your pro rata portion of our undistributed foreign personal holding company income. If you dispose of your shares prior to such date, you will not be subject to tax under these rules. We do not believe we are a foreign personal holding company presently and we do not expect to become one. However, we can not assure you that we will not qualify as a foreign personal holding company in the future.

Passive Foreign Investment Company

We believe that our subordinate voting shares should not currently be treated as stock of a passive foreign investment company for United States federal income tax purposes, but this conclusion is a factual determination made annually and thus may be subject to change based on future operations. In general, we will be a passive foreign investment company with respect to a U.S. Holder if, for any taxable year in which the U.S. Holder holds our subordinate voting shares, either:

68

- at least 75% of our gross income for the taxable year is passive income; or

- at least 50% of the average value of our assets is attributable to assets that produce or are held for the production of passive income.

For this purpose, passive income includes income such as:

- dividends;

- interest;

- rents or royalties, other than certain rents or royalties derived from the active conduct of trade or business;

- annuities; or

- gains from assets that produce passive income.

If a foreign corporation owns at least 25% by value of the stock of another corporation, the foreign corporation is treated for purposes of the passive foreign investment company tests as owning its proportionate share of the assets of the other corporation and as receiving directly its proportionate share of the other corporation's income.

If we are treated as a passive foreign investment company, a U.S. Holder that did not make a qualified electing fund election or, if available, a mark-to-market election, as described below, would be subject to special rules with respect to:

- any gain realized on the sale or other disposition of subordinate voting shares; and

- any "excess distribution" by us to the U.S. Holder.

Generally, "excess distributions" are any distributions to the U.S. Holder in respect of the subordinate voting shares during a single taxable year that are greater than 125% of the average annual distributions received by the U.S. Holder in respect of the subordinate voting shares during the three preceding taxable years or, if shorter, the U.S. Holder's holding period for the subordinate voting shares.

Under the passive foreign investment company rules,

- the gain or excess distribution would be allocated ratably over the U.S. Holder's holding period for the subordinate voting shares;

- the amount allocated to the taxable year in which the gain or excess distribution was realized would be taxable as ordinary income;

- the amount allocated to each prior year, with certain exceptions, would be subject to tax at the highest tax rate in effect for that year; and

- the interest charge generally applicable to underpayments of tax would be imposed in respect of the tax attributable to each such year.

A U.S. Holder owning actually or constructively "marketable stock" of a passive foreign investment company may be able to avoid the imposition of the passive foreign investment company tax rules described above by making a mark-to-market election. Generally, pursuant to this election, such holder would include in ordinary income, for each taxable year during which such stock is held, an amount equal to the increase in value of the stock, which increase will be determined by reference to the value of such stock at the end of the current taxable year compared with their value as of the end of the prior taxable year. Holders desiring to make the mark-to-market election should consult their tax advisors with respect to the application and effect of making such election.

In the case of a U.S. Holder who does not make a mark-to-market election, the special passive foreign investment company tax rules described above will not apply to such U.S. Holder if the U.S. Holder makes an election to have us treated as a qualified electing fund and we provide certain required information to holders. For a U.S. Holder to make a qualified electing fund election, we would have to satisfy certain reporting requirements. We have not determined whether we will undertake the necessary measures to be able to satisfy such requirements in the event that we were treated as a passive foreign investment company.

69

A U.S. Holder that makes a qualified electing fund election will be currently taxable on its pro rata share of our ordinary earnings and net capital gain, at ordinary income and capital gains rates, respectively, for each of our taxable years, regardless of whether or not distributions were received. The U.S. Holder's basis in the subordinate voting shares will be increased to reflect taxed but undistributed income. Distributions of income that had previously been taxed will result in a corresponding reduction of basis in the subordinate voting shares and will not be taxed again as a distribution to the U.S. Holder. U.S. Holders desiring to make a qualified electing fund election should consult their tax advisors with respect to the advisability of making such election.

UNITED STATES BACKUP WITHHOLDING AND INFORMATION REPORTING

A U.S. Holder may be subject to information reporting with respect to dividends paid on, or proceeds of the sale or other disposition of, our subordinate voting shares, unless the U.S. Holder is a corporation or comes within certain other categories of exempt recipients. A U.S. Holder that is not an exempt recipient may be subject to backup withholding at a rate of 31% with respect to the proceeds from the sale or the disposition of, or with respect to dividends on, subordinate voting shares unless the U.S. Holder provides a taxpayer identification number and otherwise complies with applicable requirements of the backup withholding rules. Any amount withheld under these rules will be creditable against the U.S. Holder's U.S. federal income tax liability or refundable to the extent that it exceeds such liability. A U.S Holder who does not provide a correct taxpayer identification number may be subject to penalties imposed by the United States Internal Revenue Service.

Non-U.S. Holders may be subject to information reporting and possible backup withholding with respect to the proceeds of the sale or other disposition of subordinate voting shares effected within the United States, unless the holder certifies to its foreign status or otherwise establishes an exemption if the broker does not have actual knowledge that the holder is a U.S. holder.

Treasury regulations will modify certain of the rules discussed above with respect to payments on the subordinate voting shares made after December 31, 2000. In particular, a payor within the United States will be required to withhold 31% of any payments of dividends on or proceeds from the sale of subordinate voting shares within the United States to a non-exempt U.S. or Non-U.S. Holder if such holder fails to provide appropriate certification. In the case of such payments by a payor within the United States to a foreign partnership other than a foreign partnership that qualifies as a "withholding foreign partnership" within the meaning of such Treasury regulations, the partners of such partnership will be required to provide the certification discussed above in order to establish an exemption from backup withholding tax and information reporting requirements.

CANADIAN FEDERAL INCOME TAX CONSIDERATIONS

In the opinion of Fasken Martineau DuMoulin LLP, the following is a summary of the material Canadian federal income tax considerations generally applicable to a U.S. person who holds subordinate voting shares and who, for the purposes of the Income Tax Act (Canada), or the ITA, and the Canada-United States Income Tax Convention (1980), or the Convention, as applicable and at all relevant times:

- is resident in the United States and not resident in Canada,

- holds the subordinate voting shares as capital property,

- does not have a "permanent establishment" or "fixed base" in Canada, as defined in the Convention; and

- deals at arm's length with us. Special rules, which are not discussed below, may apply to "financial institutions", as defined in the ITA, and to non-resident insurers carrying on an insurance business in Canada and elsewhere.

This discussion is based on the current provisions of the ITA and the regulations promulgated under the ITA and the Convention, all specific proposals to amend the ITA or the regulations promulgated under the ITA announced by or on behalf of the Canadian Minister of Finance prior to the date of this Offering Circular and the current published administrative practices of the Canada Customs and Revenue Agency, or the Agency. It does

70

not otherwise take into account or anticipate any changes in law or administrative practice nor any income tax laws or considerations of any province or territory of Canada or any jurisdiction other than Canada, which may differ from the Canadian federal income tax consequences described in this document.

Under the ITA and the Convention, dividends paid or credited, or deemed to be paid or credited, on the subordinate voting shares to a U.S. person who owns less than 10% of the voting shares will be subject to Canadian withholding tax at the rate of 15% of the gross amount of those dividends or deemed dividends. If a U.S. person is a corporation and owns 10% or more of the voting shares, the rate is reduced from 15% to 5%. As described above and subject to specified limitations, a U.S. person may be entitled to credit against U.S. federal income tax liability for the amount of tax withheld by Canada.

Under the Convention, dividends paid to specified religious, scientific, charitable and similar tax exempt organizations and specified organizations that are resident and exempt from tax in the United States and that have complied with specified administrative procedures are exempt from this Canadian withholding tax.

A capital gain realized by a U.S. person on a disposition or deemed disposition of the subordinate voting shares will not be subject to tax under the ITA unless the subordinate voting shares constitute taxable Canadian property within the meaning of the ITA at the time of the disposition or deemed disposition. In general, the subordinate voting shares will not be "taxable Canadian property" to a U.S. person if they are listed on a prescribed stock exchange, which includes The Toronto Stock Exchange, unless, at any time within the five-year period immediately preceding the dispositions, the U.S. person, persons with whom the U.S. person did not deal at arm's length, or the U.S. person together with those persons, owned or had an interest in or a right to acquire more than 25% of any class or series of our shares.

If the subordinate voting shares are taxable Canadian property to a U.S. person, any capital gain realized on a disposition or deemed disposition of those subordinate voting shares will generally be exempt from tax under the ITA by virtue of the Convention if the value of the subordinate voting shares at the time of the disposition or deemed disposition is not derived principally from real property, as defined by the Convention, situated in Canada. The determination as to whether Canadian tax would be applicable on a disposition or deemed disposition of the subordinate voting shares must be made at the time of the disposition or deemed disposition.

POTENTIAL PURCHASERS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS TO DETERMINE THE PARTICULAR TAX CONSEQUENCES TO THEM, INCLUDING THE APPLICATION AND EFFECT OF ANY STATE, LOCAL OR FOREIGN INCOME AND OTHER TAX LAWS, OF THE ACQUISITION, OWNERSHIP AND DISPOSITION OF SUBORDINATE VOTING SHARES.

In the purchase agreement, each of the underwriters have severally agreed to purchase all of the shares sold under the purchase agreement if any of these shares are purchased. The obligations of the underwriters under the purchase agreement may be terminated at their discretion on the basis of their assessment of the state of the financial markets and also upon the occurrence of certain stated events. Under the purchase agreement, the commitments of non-defaulting underwriters may be increased.

This offering is being made concurrently in the United States and in all of the provinces of Canada. The subordinate voting shares will be offered in the United States and Canada through the underwriters either directly or through their respective U.S. or Canadian registered broker-dealer affiliates or agents. Subject to applicable law, the underwriters may offer the subordinate voting shares outside of Canada and the United States.

We have agreed to indemnify the underwriters against certain liabilities, including liabilities under the U.S. Securities Act and applicable Canadian securities legislation, or to contribute to payments the underwriters may be required to make in respect of those liabilities.

The underwriters are offering the shares, subject to prior sale, when, as and if issued to and accepted by them, subject to approval of legal matters by their counsel, including the validity of the shares and other conditions contained in the purchase agreement, such as the receipt by the underwriters of officer's certificates and legal opinions. The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.

The subordinate voting shares will be ready for delivery in New York, New York on or about , 2000.

COMMISSIONS

The representatives have advised us that the underwriters propose initially to offer the shares to the public at the initial public offering price on the cover page of this prospectus. With respect to the offering in the United States, the underwriters may offer the shares to dealers at the initial public offering price less a concession not in excess of $ per share and the underwriters may allow and the dealers may reallow, a discount not in excess of $ per share to other dealers. After the initial public offering, the public offering price, concession and discount may be changed.

The following table shows the public offering price, underwriting commission and proceeds before expenses to EXFO. The information assumes either no exercise or full exercise by the underwriters of their over-allotment option.

The public offering price for subordinate voting shares offered in the United States is payable in U.S. dollars and the public offering price for subordinate voting shares offered in Canada is payable in Canadian dollars. The U.S. dollar amount is the equivalent of the Canadian price of the subordinate voting shares based on the prevailing U.S. -- Canadian dollar exchange rate as of the date of this prospectus. See "Exchange Rate Information."

The expenses of this offering, not including the underwriting commission, are estimated at $1,000,000 and are payable by EXFO.

OVER-ALLOTMENT OPTION

We have granted options to the underwriters to purchase up to 900,000 additional shares at the public offering price less the underwriting commission. The underwriters may exercise these options for 30 days from the date of this prospectus solely to cover any over-allotments. If the underwriters exercise these options, each will be obligated, subject to conditions contained in the purchase agreement, to purchase a number of additional shares proportionate to that underwriter's initial amount reflected in the above table.

RESERVED SHARES

At our request, the underwriters have reserved for sale, at the initial public offering price, up to 7% of the shares offered by this prospectus for sale to some of our directors, officers, employees, distributors, dealers, business associates and related persons. If these persons purchase reserved shares, this will reduce the number of shares available for sale to the general public. Any reserved shares that are not orally confirmed for purchase within one day of the pricing of this offering will be offered by the underwriters to the general public on the same terms as the other shares offered by this prospectus. No commitment to purchase reserved shares will be accepted until after the registration statement of which this prospectus is a part is effective and a public offering price has been established.

NO SALES OF SIMILAR SECURITIES

We and our executive officers and directors and all existing shareholders have agreed not to sell or transfer any subordinate voting shares for 180 days after the date of this prospectus without first obtaining the written consent of Merrill Lynch. Specifically, we and these other individuals have agreed not to directly or indirectly:

- offer, pledge, sell or contract to sell any subordinate voting shares;

- sell any option or contract to purchase any subordinate voting shares;

- purchase any option or contract to sell any subordinate voting shares;

- grant any option, right or warrant for the sale of any subordinate voting shares;

- lend or otherwise dispose of or transfer any subordinate voting shares;

- request or demand that we file a registration statement related to the subordinate voting shares; or

- enter into any swap or other agreement that transfers, in whole or in part, the economic consequence of ownership of any subordinate voting shares whether any such swap or transaction is to be settled by delivery of shares or other securities, in cash or otherwise.

This lockup provision applies to subordinate voting shares and to securities convertible into or exchangeable or exercisable for or repayable with subordinate voting shares. It also applies to subordinate voting shares owned now or acquired later by the person executing the agreement or for which the person executing the agreement later acquires the power of disposition.

NASDAQ NATIONAL MARKET AND TORONTO STOCK EXCHANGE LISTINGS AND FACTORS CONSIDERED IN DETERMINING THE INITIAL PUBLIC OFFERING PRICE

We expect the shares to be approved for quotation on the Nasdaq National Market, subject to notice of issuance, under the symbol "EXFO" and that the shares will be approved for listing on The Toronto Stock Exchange. The quotation on the Nasdaq National Market and the listing on The Toronto Stock Exchange are subject to our fulfilling all of the requirements of the Nasdaq National Market and The Toronto Stock Exchange, including the distribution of the subordinate voting shares to a minimum number of public shareholders.

Before this offering, there has been no public market for our subordinate voting shares. The initial public offering price will be determined through negotiations among us and the underwriters. In addition to prevailing market conditions, the factors to be considered in determining the initial public offering price are:

- the valuation multiples of publicly traded companies that the underwriters believe to be comparable to us;

- our financial information;

- the history of, and the prospects for, our company and the industry in which we compete;

- an assessment of our management, its past and present operations and the prospects for and timing of, our future sales;

- the present state of our development; and

- the above factors in relation to market values and various valuation measures of other companies engaged in activities similar to ours.

An active trading market for the shares may not develop. It is also possible that after this offering the shares will not trade in the public market at or above the initial public offering price.

The underwriters do not expect to sell more that 5% of the shares in the aggregate to accounts over which they exercise discretionary authority.

ELECTRONIC PROSPECTUS

Merrill Lynch will be facilitating Internet distribution for this offering to certain of its Internet subscription customers. Merrill Lynch intends to allocate a limited number of shares for sale to its online brokerage customers. An electronic prospectus is available on the Web site maintained by Merrill Lynch. Other than the prospectus in electronic format, the information on the Merrill Lynch Web site relating to this offering is not a part of this prospectus.

A prospectus in electronic format is being made available on an Internet Web site maintained by Wit SoundView's affiliate, Wit Capital Corporation. Other than the prospectus in electronic format, the information on Wit Capital's Web site and any information contained on any other Web site maintained by Wit Capital is not part of the prospectus or the registration statement of which this prospectus forms a part, has not been approved and/or endorsed by us or any underwriter in its capacity as underwriter and should not be relied upon by investors.

PRICE STABILIZATION, SHORT POSITIONS AND PENALTY BIDS

Until the distribution of the shares is completed, SEC rules may limit underwriters and selling group members from bidding for and purchasing our subordinate voting shares. However, the underwriters may engage in transactions that stabilize the price of subordinate voting shares, such as bids or purchases to peg, fix or maintain that price.

If the underwriters create a short position in the subordinate voting shares in connection with this offering, i.e., if they sell more shares than are listed on the cover of this prospectus, the underwriters may reduce that short position by purchasing shares in the open market. The underwriters may also elect to reduce any short position by exercising all or part of the over-allotment option described above. Purchases of the subordinate voting shares

74

to stabilize its price or to reduce a short position may cause the price of the subordinate voting shares to be higher than it might be in the absence of such purchases.

The underwriters may also impose a penalty bid on underwriters and selling group members. This means that if the underwriters purchase shares in the open market to reduce the underwriter's short position or to stabilize the price of such shares, they may reclaim the amount of the selling concession from the underwriters and the selling group members who sold those shares. The imposition of a penalty bid may also affect the price of the shares in that it discourages resales of those shares.

Pursuant to policy statements of the Commission des valeurs mobilieres du Quebec and the Ontario Securities Commission, the underwriters in Canada may not, throughout the period of distribution, bid for or purchase subordinate voting shares. The foregoing restriction is subject to certain exceptions, on the condition that the bid or purchase not be engaged in for the purpose of creating actual or apparent active trading in, or raising the price of, the subordinate voting shares. Such exceptions include a bid or purchase permitted under the by-laws and rules of The Toronto Stock Exchange relating to market stabilization and passive market making activities and a bid or purchase made for and on behalf of a customer where the order was not solicited during the period of distribution. We have been advised that in connection with this offering and pursuant to the first exception mentioned above, the underwriters may over-allot or effect transactions which stabilize or maintain the market price of the subordinate voting shares at levels other than those that might otherwise prevail on the open market. These transactions, if commenced, may be discontinued at any time.

Neither we nor any of the underwriters makes any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of the subordinate voting shares. In addition, neither we nor any of the underwriters makes any representation that the underwriters will engage in these transactions or that these transactions, once commenced, will not be discontinued without notice.

AUDITORS' REPORT

To the Directors of
EXFO ELECTRO-OPTICAL ENGINEERING INC.

We have audited the consolidated balance sheets of EXFO ELECTRO-OPTICAL ENGINEERING INC. as at August 31, 1999 and 1998 and the EXFO ELECTRO-OPTICAL ENGINEERING INC. statements of earnings, retained earnings and cash flows for each of the years in the three-year period ended August 31, 1999. These financial statements are the responsibility of the company's management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with Canadian generally accepted auditing standards. Those standards require that we plan and perform an audit to obtain reasonable assurance whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation.

In our opinion, these consolidated financial statements present fairly, in all material respects, the financial position of the company as at August 31, 1999 and 1998 and the results of its operations and its cash flows for each of the years in the three-year period ended in accordance with Canadian generally accepted accounting principles.

COMMENTS BY AUDITORS FOR U.S. READERS ON CANADA-U.S. REPORTING DIFFERENCE

In the United States, reporting standards for auditors require the addition of an explanatory paragraph (following the opinion paragraph) when there is a change in accounting principles that has a material effect on the comparability of the company's financial statements, such as the change described in note 2 to the financial statements. Our report to the shareholders dated October 15, 1999, is expressed in accordance with Canadian reporting standards which do not require a reference to such a change in accounting principles in the auditor's report when the change is properly accounted for and adequately disclosed in the financial statements.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

BASIS OF PRESENTATION

These consolidated financial statements have been prepared in accordance with accounting principles generally accepted in Canada. These principles conform, in all material respects, with accounting principles generally accepted in the United States, except as described in note 21. The principal accounting policies of the company, which have been consistently applied, are summarized as follows:

INTERIM FINANCIAL INFORMATION

The financial information as at February 29, 2000 and for the six months ended February 28, 1999 and February 29, 2000 is unaudited. In the opinion of management, all adjustments necessary to present fairly the results of these periods have been included. The adjustments made were of a normal recurring nature. The results of operations for the six months ended February 29, 2000 are not necessarily indicative of the operating results anticipated for the full year.

ACCOUNTING ESTIMATES

The preparation of financial statements in accordance with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Significant estimates include the allowance for doubtful accounts receivable, tax credits receivable, provisions for obsolete inventories, the useful lives of capital assets and goodwill and certain accrued liabilities. Actual results could differ from those estimates.

CONSOLIDATION

These consolidated financial statements include the accounts of the company and its wholly owned subsidiaries.

FOREIGN CURRENCY TRANSLATION

FOREIGN SUBSIDIARIES

The company's wholly owned subsidiaries are considered to be integrated. As a result, the subsidiaries' accounts are remeasured into the functional currency using the temporal method. Under this method, monetary assets and liabilities are remeasured at the exchange rates in effect at the balance sheet date. Non-monetary assets and liabilities are remeasured at historical rates. Revenue and expenses are remeasured at the average rate for the period. Gains and losses resulting from remeasurement are reflected in the statement of earnings.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES -- (CONTINUED) FOREIGN CURRENCY TRANSACTIONS

Transactions denominated in foreign currencies are measured into the functional currency using the temporal method.

FORWARD EXCHANGE CONTRACTS

The company enters into forward exchange contracts in order to hedge against potential exchange rate fluctuations on cash flows related to anticipated future revenue streams denominated in foreign currencies. Unrealized gains and losses on these forward exchange contracts are deferred and recognized upon settlement of the related transactions. Accordingly, cash flows resulting from forward exchange contract settlements are classified as cash flows from operating activities along with the corresponding cash flows being hedged.

CASH AND CASH EQUIVALENTS

Cash and cash equivalents consist of cash on hand and balances with banks and all highly liquid short-term investments with original maturities of three months or less.

SHORT-TERM INVESTMENTS

Short-term investments are valued at the lower of cost and market value.

INVENTORIES

Inventories are valued at the lower of cost and net realizable value. The cost of raw materials and work in progress inventories is determined using the first-in, first-out method. The cost of finished goods is determined using the average cost method.

CAPITAL ASSETS AND AMORTIZATION

Capital assets are recorded at cost less related government grants and research and development tax credits. Amortization is provided on a straight-line basis over the estimated useful lives of the capital assets as follows:

                                                          TERM
                                                          ----
Equipment                         3 to 5 years
Leasehold improvements            Remaining lease term including lease renewal option

The carrying value of capital assets is evaluated whenever significant events occur which may indicate an impairment in value, based upon a comparison of the carrying value to the net recoverable amount.

GOODWILL, OTHER ASSETS AND AMORTIZATION

Goodwill, which represents the excess of the purchase price of an acquired business over the net identifiable assets acquired, is amortized on a straight-line basis over the estimated useful life of five years. The company assesses the carrying value of goodwill for future recoverability on an annual basis by estimating the associated net undiscounted future cash flows. The amount of impairment loss, if any, is the excess of the carrying value over the estimated net undiscounted cash flows. Goodwill is written down for any permanent impairment in value of the unamortized portion.

Other assets include the cost of acquired patents, net of accumulated amortization. Patents are amortized on a straight-line basis over the estimated useful lives of four years.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES -- (CONTINUED) GOVERNMENT GRANTS

Government grants are accrued as a receivable when there is reasonable assurance that the company has complied and will continue to comply with all the conditions related to the grant. Grants related to operating expenses are included in earnings when the related expenses are incurred. Grants related to capital expenditures are deducted from the related asset. Grants related to job creation programs for extended periods are deferred and amortized on a straight-line basis over five years, the minimum period for which the created job must be maintained.

REVENUE RECOGNITION

For products where the software is incidental, the company recognizes revenue when the products are delivered, with provisions made for warranties and support obligations.

For products where software is not incidental, the revenues are separated into two components, product and customer support revenues based upon vendor-specific objective evidence of fair value. The product revenues for these sales are recognized when the products are delivered with provisions made for estimated returns and warranties. The customer support revenues are deferred and recognized ratably over the period of the support arrangement, except where provided within one year of delivery, costs of providing this support is insignificant and accrued at the time of delivery and no upgrades of software are provided. Prior to September 1, 1998, the revenues for support were included in sales upon delivery with a provision for any costs associated with future support obligations where the support was provided for one year or less, the estimated cost of providing the support was insignificant and where enhancements offered have been and are expected to be minimal. The effect of this accounting change for the years ended August 31, 1997 and 1998 was not determinable by the company. For the year ended August 31, 1999, the company deferred revenues amounting to $327,000 which had an effect on net earnings of $226,000. The change resulted in a reduction in net earnings per share for the year ended August 31, 1999 of $0.01.

ADVERTISING COSTS

Advertising costs are expensed as incurred.

INCOME TAXES

The company provides for income taxes using the liability method of tax allocation. Under this method, future income tax assets and liabilities are determined based on deductible or taxable temporary differences between financial statement values and tax values of assets and liabilities using enacted income tax rates expected to be in effect for the year in which the differences are expected to reverse.

The company establishes a valuation allowance against future income tax assets if, based on available information, it is more likely than not that some or all of the future income tax assets will not be realized.

TAX CREDITS

The company is entitled to scientific research and experimental development
("SRED") tax credits granted by the Canadian federal government ("Federal")
and the government of the Province of Quebec ("Provincial"). Federal SRED tax credits are earned on qualified Canadian SRED expenditures at a rate of 20% and can only be used to offset Federal income taxes otherwise payable. Provincial SRED tax credits, which are refundable, are earned on qualified SRED salaries in the Province of Quebec at a rate of 20%. Additional refundable provincial SRED tax credits are earned at a rate of up to 20%. These additional tax credits are reduced to nil, on a pro-rata basis, as total assets of the company increase from Cdn$25 million to Cdn$50 million.

SRED tax credits are accounted for as a reduction of the related expenditures. The refundable portion of SRED tax credits is recorded in the year in which the related expenditures are incurred. The non-refundable portion of SRED tax credits is recorded in the year in which the related expenditures are incurred, provided the company has reasonable assurance the credits will be realized.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES -- (CONTINUED) RESEARCH AND DEVELOPMENT EXPENSES

All expenses related to development activities, which do not meet generally accepted criteria for deferral, and research are expensed as incurred. Development expenses which meet generally accepted criteria for deferral are capitalized and amortized against earnings over the estimated period of benefit.

As at February 29, 2000, the company had not deferred any development costs.

STOCK-BASED COMPENSATION PLAN

The company maintains a stock-based compensation plan, which is described in note 13. Under accounting principles generally accepted in Canada, no compensation cost is recognized for this plan when shares are issued to plan participants. Any consideration received from plan participants is credited to share capital.

EARNINGS AND DIVIDENDS PER SHARE

Basic earnings and dividends per share are determined using the weighted average number of common shares outstanding during the period, as adjusted for the effects of stock splits and other reorganizations of share capital in prior periods.

Fully diluted earnings per share is determined using the weighted average number of shares and dilutive share equivalents outstanding during the period. Earnings for the period are increased by the estimated additional earnings, net of applicable income taxes, on the proceeds, if any, from the exercise of dilutive common share equivalents.

ACCOUNTING CHANGES

During 1999, the company retroactively adopted the recently revised recommendations of the Canadian Institute of Chartered Accountants (CICA) regarding accounting for income taxes. Under these revised recommendations, income taxes are now accounted for using the liability method. These new recommendations are consistent with those of SFAS 109 under accounting principles generally accepted in the United States. The adoption of these revised recommendations did not result in any changes to prior years' earnings, shareholders' equity or cash flows. However, certain additional disclosures have been provided.

The company also retroactively applied the new recommendations of the CICA regarding statements of cash flows. The application of this new basis of presentation did not have any effect on prior years' earnings or shareholders' equity. However, certain comparative figures have been reclassified in order to conform with the new basis of presentation.

3. CHANGE IN REPORTING CURRENCY

The consolidated financial statements of the company were presented in Canadian dollars up to August 31, 1999. Effective September 1, 1999, the U.S. dollar has been adopted as the reporting currency. The functional currency continues to be the Canadian dollar. The financial statements for the years ended August 31, 1997, 1998 and 1999 and the six months ended February 28, 1999 are presented in U.S. dollars in accordance with a translation of convenience method using the representative exchange rate as at August 31, 1999 of US$1.00 = Cdn$1.4958. The translated amount for monetary and non-monetary items as at August 31, 1999 becomes the historical basis for those items in subsequent periods.

The financial statements as at February 29, 2000 and for the six months then ended have been translated using the current rate method. Under this method, the financial statements are translated into the reporting currency as follows: assets and liabilities are translated at the exchange rate in effect at the date of the balance sheet and revenue and expenses are translated at the average exchange rate for the period. All gains and losses from the translation of the financial statements into the reporting currency are included in the cumulative translation adjustment in shareholders' equity. Changes in the cumulative translation adjustment during each period result solely from the application of this translation method.

It is management's intention to declare dividends, if any, in Canadian dollars.

4. BUSINESS COMBINATIONS

NORTECH ACQUISITION

On February 4, 2000, the company acquired a 100% interest in Nortech Fibronic Inc. ("Nortech"), a company specializing in fiber-optic testing and temperature sensing, in exchange for total consideration valued at Cdn$4,051,000 (US$2,799,000). The consideration paid consisted of Cdn$3,051,000 (US$2,108,000) in cash, the issuance of 800,000 Class G shares which are mandatorily redeemable, for cash or Class A shares at the option of the company, on November 30, 2000 for an amount of Cdn$800,000 (US$553,000) (note 11), and a non-interest-bearing debenture in the amount of Cdn$200,000 (US$138,000) due November 30, 2000.

This acquisition, which has been accounted for using the purchase method, resulted in goodwill amounting to Cdn$3,677,000 (US$2,542,000) based on the following allocation of the purchase price to the identifiable assets acquired and liabilities assumed.

REORGANIZATION

On September 1, 1998, the company acquired, from its parent company, all the issued and outstanding shares of GEXFO Distribution Internationale Inc. in exchange for 1 Class C share of the company, which was redeemed at a price of Cdn$509,000 (US$340,000). This holding company has two wholly owned subsidiaries, EXFO America Inc. and EXFO Europe S.A.R.L., which market fiber-optic test and measurement and monitoring equipment and instruments for the American and European markets.

Since the exchange was between entities under common control, the exchange has been accounted for in a manner similar to a pooling of interests. The assets, liabilities and shareholders' equity of the company and the other companies have been combined using their respective carrying amounts and financial statements of prior periods have been restated as if the companies had always been combined. The statements of earnings and cash flows for 1997 and 1998 reflect the results of operations and cash flows on a combined basis. The creation, issuance and redemption of the Class C share on September 1, 1998 has been presented as a mandatorily redeemable preferred share and a dividend distribution from the combined retained earnings.

The combined companies' net assets as at August 31, 1998 are as follows:

On September 2, 1998, the company filed articles of amendment pursuant to which the Class A shares were split on a 190,000-to-one basis. Pursuant to articles of amendment dated September 3, 1998, the 100 issued and outstanding Class E shares (note 11) were converted into Class A shares on a 190,000-to-one basis. All references to numbers of shares and per share amounts have been restated in order to reflect the share split and conversion noted above.

In accordance with a stock purchase plan established by the company, officers, directors and key employees may purchase Class F shares up to a maximum of 5% of all participating, issued and outstanding shares of the company.

Shares issued under the plan are restricted as to sale and transferability for a period of at least five years. As at February 29, 2000, employees have subscribed for, and the company is committed to issue, an aggregate of 504,650 Class F shares in exchange for a weighted average cash consideration of Cdn$1.12 (US$0.78) per share.

FAIR VALUE

Cash and cash equivalents, accounts receivable, bank advances, accounts payable and accrued liabilities, dividend payable, mandatorily redeemable preferred shares, loan from a company under common control and long-term debt are financial instruments whose fair values approximate their carrying values.

The fair value of short-term investments, determined based on market value, amounted to $1,343,000 and $1,430,000 as at August 31, 1998 and August 31, 1999, respectively.

CREDIT RISK

Financial instruments which potentially subject the company to credit risk consist principally of cash and cash equivalents, short-term investments, accounts receivable and forward exchange contracts. The company's short-term investments consist of debt instruments issued by high-credit quality financial institutions and corporations and the company's cash and cash equivalents and forward exchange contracts are held with or issued by high-credit quality financial institutions; therefore the company considers the risk of non-performance on these instruments to be remote.

Due to the North American and European distribution of the company's customers, there is no particular concentration of credit risk. Generally, the company does not require collateral or other security from customers for trade accounts receivable, however, credit is extended to customers following an evaluation of creditworthiness. In addition, the company performs ongoing credit reviews of all its customers and establishes an allowance for doubtful accounts receivable when accounts are determined to be uncollectible.

INTEREST RATE RISK

As at February 29, 2000, the company's exposure to interest rate risk is summarized as follows:

Cash and cash equivalents...................................   Non-interest bearing
Accounts receivable.........................................   Non-interest bearing
Bank advances...............................................   Prime rate plus nil to 1.25%
Accounts payable and accrued liabilities....................   Non-interest bearing
Mandatorily redeemable preferred shares.....................   Non-interest bearing
Loan from a company under common control....................   Prime rate plus 1%

19. FINANCIAL INSTRUMENTS -- (CONTINUED) FORWARD EXCHANGE CONTRACTS

The company is exposed to currency risks as a result of its export sales, substantially all of which are denominated in U.S. dollars, of products manufactured in Canada. These risks are partially hedged by forward exchange contracts and certain operating expenses. As at August 31, 1998 and 1999 and February 29, 2000, the company held contracts to sell U.S. dollars at various forward rates, which are summarized as follows:

                                                                                 WEIGHTED

As at August 31, 1998
  September 1998 to August 1999.............................      $4,800          1.4058
  September 1999 to June 2000...............................       2,900          1.4531
As at August 31, 1999
  September 1999 to August 2000.............................      $5,800          1.4815
  September 2000 to June 2001...............................       3,000          1.5014
As at February 29, 2000 (unaudited)
  March 2000 to February 2001...............................      $5,700          1.4989
  March 2001 to November 2001...............................       1,900          1.4800

As at August 31, 1998 and 1999, these contracts resulted in deferred unrealized losses amounting to US$693,000 and US$35,000, respectively (as at February 29, 2000 -- deferred unrealized gain amounting to US$285,000).

20. UNCERTAINTY DUE TO THE YEAR 2000 ISSUE

The Year 2000 Issue arises because many computerized systems use two digits rather than four to identify a year. Date-sensitive systems may recognize the year 2000 as 1900 or some other date, resulting in errors when information using year 2000 dates is processed. In addition, similar problems may arise in some systems which use certain dates in 1999 to represent something other than a date. The effects of the Year 2000 Issue may be experienced before, on, or after January 1, 2000, and, if not addressed, the impact on operations and financial reporting may range from minor errors to significant systems failure which could affect an entity's ability to conduct normal business operations. It is not possible to be certain that all aspects of the Year 2000 Issue affecting the company, including those related to the efforts of customers, suppliers, or other third parties, will be fully resolved.

21. UNITED STATES GENERALLY ACCEPTED ACCOUNTING PRINCIPLES

As a registrant with the Securities and Exchange Commission in the United States, the company is required to reconcile its financial results for significant differences between generally accepted accounting principles as applied in Canada (Canadian GAAP) and those applied in the United States (U.S. GAAP).

Additional disclosures required under U.S. GAAP have been provided in the accompanying financial statements and notes. In addition, the following summarizes differences between Canadian and U.S. GAAP and other required disclosures under U.S. GAAP.

ACCOUNTING FOR STOCK-BASED COMPENSATION

Under U.S. GAAP, the company has elected to measure stock-based compensation costs using the intrinsic value method (APB 25). Under this method, compensation cost is measured as the difference between the

(tabular amounts in thousands of U.S. dollars, except share and per share data and as otherwise noted) -- (Continued)

21. UNITED STATES GENERALLY ACCEPTED ACCOUNTING PRINCIPLES -- (CONTINUED) fair value of the purchased stock and the purchase price paid by plan participants. Compensation cost is amortized to expense over a period of five years, being the restriction period (note 13). Under Canadian GAAP, no compensation cost is recognized.

During the year ended August 31, 1999 and the six months ended February 29, 2000, the weighted average fair value per share under the stock purchase plan amounted to approximately $0.68 and $6.87, respectively. The fair value per share since inception of the plan ranged between $0.68 and $18.00. As at August 31, 1999 and February 29, 2000, the balance of deferred stock-based compensation amounted to $40,000 and $2,711,000, respectively (August 31, 1998 -- nil).

CHANGE IN REPORTING CURRENCY

As mentioned in note 3, on September 1, 1999, the company adopted the U.S. dollar as its reporting currency. Under U.S. GAAP, the financial statements, including prior years, are translated according to the current rate method. Under Canadian GAAP, at the time of change in reporting currency, the historical financial statements are presented using a translation of convenience.

Under Canadian GAAP, the statements of earnings for the years ended August 31, 1997, 1998 and 1999 and the six months ended February 28, 1999 were translated into U.S. dollars using an exchange rate of US$1.00 = Cdn$1.4958. Under U.S. GAAP, revenue and expenses would be translated at exchange rates prevailing at the respective transaction dates. Average exchange rates for the years ended August 31, 1997, 1998 and 1999 and the six months ended February 28, 1999 were US$1.00 = Cdn$1.3685, Cdn$1.4390, Cdn$1.5068 and Cdn$1.5274, respectively. The exchange rates as at August 31, 1998 and 1999 were US$1.00 = Cdn$1.5722 and Cdn$1.4958, respectively.

SHORT-TERM INVESTMENTS

Under U.S. GAAP, the short-term investments would be classified as "available for sale" securities. Consequently, these securities would be carried at fair value, with any unrealized holding gains or losses at each balance sheet date being reflected in other comprehensive income on a net of tax basis. Under Canadian GAAP, short-term investments are carried at the lower of cost and market value.

IMPAIRMENT OF LONG-LIVED ASSETS

In accordance with SFAS 121, Accounting for the impairment of long-lived assets and for long-lived assets to be disposed of, the company reviews the carrying value of its long-lived assets, including goodwill associated with assets acquired in a purchase business combination, when events or changes in circumstances indicate that the carrying value may not be recoverable. If this review indicates that the carrying amounts of the assets and goodwill, where applicable, will not be recoverable, as determined based on estimated undiscounted cash flows, an impairment loss is recorded. Impairment losses, if any, are measured as the excess of the carrying values over the fair values of the related assets. In addition, goodwill is reviewed periodically as disclosed in note 2.

FORWARD EXCHANGE CONTRACTS

Under U.S. GAAP, in accordance with SFAS 52, certain of the forward exchange contracts held by the company, for which the underlying sales transactions are not firmly committed, would not qualify for hedge accounting. Consequently, unrealized gains or losses on these contracts at each balance sheet date would be reflected in earnings for the corresponding period. Under Canadian GAAP, all of the company's forward

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(tabular amounts in thousands of U.S. dollars, except share and per share data and as otherwise noted) -- (Continued)

21. UNITED STATES GENERALLY ACCEPTED ACCOUNTING PRINCIPLES -- (CONTINUED) exchange contracts qualify for hedge accounting, therefore, any unrealized gains or losses are deferred and recognized in the statement of earnings upon settlement of the related transactions.

EARNINGS PER SHARE

For purposes of earnings per share calculations, the Class A, E and F shares, collectively, are considered to constitute common shares.

Under U.S. GAAP, diluted net earnings per share is calculated based on the weighted average number of common shares outstanding during the period, plus the effects of potential common shares, such as options, and conversions of senior shares outstanding during the period. This method requires that diluted net earnings per share be calculated, using the treasury stock method, as if all potential common shares had been exercised at the later of the beginning of the period or the date of issue, as the case may be, and that the funds obtained thereby were used to purchase common shares of the company at the average fair value of the common shares during the period.

Under U.S. GAAP, the presentation of per share figures for earnings before amortization of goodwill is not permitted. In addition, under U.S. GAAP, amortization of goodwill would be included in the computation of earnings from operations.

FUTURE INCOME TAXES

As a result of adjustments from Canadian GAAP to U.S. GAAP, future income tax liabilities under U.S. GAAP include an adjustment of $(67,000) as at August 31, 1998, $23,000 as at August 31, 1999 and $51,000 as at February 29, 2000 related to short-term investments and forward exchange contracts carried at fair value.

NEW ACCOUNTING STANDARDS

In 1998, the Financial Accounting Standards Board issued Statement of Financial Accounting Standard ("SFAS") No. 133, "Accounting for Derivative Instruments and Hedging Activities". The standard, which must be applied prospectively, is effective for all fiscal quarters of all fiscal years beginning after June 15, 2000. Under SFAS No. 133, all of the company's forward exchange contracts would qualify for hedge accounting. Consequently, all of the company's forward exchange contracts would be carried on the balance sheet at fair value and any unrealized gains or losses at each balance sheet date would be included in other comprehensive income.

On December 3, 1999, the Securities and Exchange Commission issued Staff Accounting Bulletin ("SAB") 101, "Revenue Recognition". SAB101, as amended by SAB+101A, is effective commencing in the first fiscal quarter of the first fiscal year beginning after December 15, 1999. The implementation of this SAB is not expected to have any material effect on the company's financial statements or revenue recognition policy in future periods.

RECONCILIATION OF NET EARNINGS TO CONFORM WITH U.S. GAAP

The following summary sets out the material adjustments to the company's reported net earnings and net earnings per share which would be made to conform with U.S. GAAP.

The number of common shares issuable upon the assumed conversion of the Class G shares has been determined by dividing the paid-in value of the Class G shares by the estimated fair value of the Class A shares as at February 4, 2000 (the date the Class G shares were issued), or $18.00 per Class A share, weighted from the date of issuance of the Class G shares to the end of the period.

As a result of the above adjustments to net earnings, differences with respect to the shareholders' equity under U.S. GAAP are as follows:

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

The Registrant's by-laws provide that the Registrant will indemnify any of its directors, former directors, officers and former officers and other parties specified by the by-laws, against all costs reasonably incurred by them for any civil, criminal or administrative action or proceeding to which they are or may made a party by reason of having been a director or officer. The indemnity covers amounts paid to settle actions or to satisfy judgments. However, the Registrant may only indemnify such these persons, if such person acted honestly and in good faith with a view to the Registrant's best interests and, in the case of a criminal or administrative action or proceeding, if such person has reasonable grounds for believing that his or her conduct was lawful. The Canada Business Corporations Act provides that court approval is required for the payment of any indemnity in connection with an action brought by or on the Registrant's behalf.

A policy of directors' and officers' liability insurance is maintained by the Registrant which insures directors and officers of the Registrant and its subsidiaries against liability incurred by, arising from or against them for certain of their acts, errors or omissions.

Reference is made to the Underwriting Agreement, the proposed form of which is filed as Exhibit 1.1, which contains provisions for the indemnification by the Underwriters of the Registrant and directors and officers of the Registrant who signed the Registration Statement against certain civil liabilities under the U.S. Securities Act of 1933.

Reference is made to Item 17 for the undertakings of the Registrant with respect to indemnification for liabilities arising under the U.S. Securities Act of 1933.

ITEM 17. UNDERTAKINGS.

(a) The Registrant undertakes to provide to the underwriter at the closing specified in the underwriting agreements certificates in such denominations and registered in such names as required by the underwriter to permit prompt delivery to each purchaser.

(b) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions or otherwise, the Registrant has been informed that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defence of any action, suit or proceeding) is asserted by such director, officer nor controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of their counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by them is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

(c) The Registrant hereby undertakes that:

(i) For purposes of determining any liability under the Securities Act of 1933, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the Registrant pursuant to Rule 424(b) (1) or
(4) or 497(h) under the Securities Act shall be deemed to be part of this registration statement as of the time it was declared effective.

(ii) For the purpose of determining any liability under the Securities Act of 1933, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein and this offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

CODE OF GENERAL BY-LAWS OF

EXFO ELECTRO-OPTICAL ENGINEERING INC.
(the "Corporation")

enacted pursuant to the
Canada Business Corporations Act

DEFINITIONS

For the purposes of these By-laws, unless otherwise provided :

- "Act" means the Canada Business Corporations Act, R.S.C. (1985) ch. C-44, as well as any amendment which may be made thereto, and any act which may be substituted therefor;

- "Articles" means the articles of association, of amalgamation or of continuance of the Corporation, as amended from time to time;

- "Auditor" means the auditor of the Corporation and includes an auditing firm;

- "Ordinary Resolution" means a resolution adopted by the majority of the votes cast by the shareholders qualified to vote in the circumstances, or signed by all of them;

- "Resident Canadian" has the particular meaning ascribed by the Act to such expression, but summarily includes a Canadian citizen and a permanent resident, within the meaning of the Immigration Act, who ordinarily reside in Canada;

LOCATION OF REGISTERED OFFICE AND OFFICES

1. Registered office. The registered office of the Corporation is situated in the city or regional municipality recorded in the Articles, at the address determined by the Board of Directors.

2. Offices. The Corporation may, in addition to its registered office, establish elsewhere within or outside Canada any other office and agency.

SHAREHOLDERS

3. Annual meetings. The annual meeting of the shareholders of the Corporation shall be held yearly on the date and at the time the Board of Directors may determine in order to receive and examine the financial statements and, if any, the report of the Auditor, elect directors, appoint an


Auditor and fix or authorize the Board of Directors to fix his remuneration and to examine, deal with and dispose of such other business as may properly come before the meeting.

4. Special meetings. Special meetings of the shareholders may be called at any time as determined by the President or the Board of Directors and shall be called by the Board of Directors when required by one or more shareholders holding no less than five per cent (5%) of the issued shares of the Corporation carrying the right to vote at a meeting in conformity with the Act.

5. Place of meetings. Meetings of the shareholders shall be held in Canada at the registered office of the Corporation or at any other place that may be fixed by the Board of Directors. Meetings of the shareholders may be held outside Canada if all shareholders entitled to vote thereat so agree; a shareholder who attends such meeting is deemed to have so agreed, unless he is present for the express purpose of objecting to the transaction of any business on the grounds that the meeting is not lawfully held.

6. Notice of meetings. Notice of each annual meeting and of each special meeting of the shareholders shall be delivered to the shareholders entitled to vote thereat, the directors and the Auditor or, at the discretion of the person charged with the giving of such notice, mailed by ordinary mail, transmitted by facsimile or sent by electronic mail to the addressees at their respective addresses entered in the books of the Corporation, no less than twenty-one (21) days and no more than fifty (50) days prior to the date fixed for the meeting. If the address of the addressee is not entered in the books of the Corporation, the notice may be sent as aforesaid to the address that the person sending the notice considers to be most likely to reach such addressee promptly. Any irregularity in the notice of meeting or giving thereof, including the accidental omission to send such notice or failure to receive on the part of the shareholder, shall in no way affect the validity of proceedings of the meeting in question.

Such notice shall specify the date, time and place of the meeting. The notice of the annual meeting may, but need not, specify the nature of the business when such meeting is called only to examine the financial statements along with the report of the Auditor, to elect directors and to re-appoint the incumbent Auditor. The notice of the annual meeting at which other business shall be transacted, as well as the notice of special meeting, shall state:

(a) the nature of business to be considered in sufficient detail to permit the shareholders to form a reasoned judgment thereon; and

(b) the text of any Special Resolution to be submitted to the meeting.

It is not necessary to give notice of the reconvening of an adjourned meeting other than by announcement at the earlier meeting that is adjourned; a new notice of meeting shall, however, be required if the shareholders' meeting is adjourned one (1) or more times for an aggregate of thirty (30) days or more.


The signature of any notice of meeting may be written, stamped, typewritten, printed or otherwise mechanically reproduced.

A certificate of the Secretary or of any other duly authorized officer of the Corporation in office at the time of the making of the certificate or of any officer, transfer agent or registrar of transfers of shares of the Corporation shall be conclusive evidence that may be set up against any shareholder or director of the sending or delivery of a notice of meeting.

7. Record date. Subject to section 134 of the Act, directors may by resolution fix in advance a date and time as the record date to determine which shareholders are entitled to (i) receive notice of meetings of shareholders,
(ii) vote at meetings of shareholders and (iii) receive financial statements of the Corporation in accordance with subsection 159(1) of the Act.

Should the directors fail to fix a date and time in advance as a record date for any aforementioned issue for any meetings of shareholders of the Corporation, the following provisions shall apply, as the case may be:

(a) the record date used to determine which shareholders are entitled to receive notice of meetings of shareholders shall be fixed at the close of business of the day immediately preceding that on which notice has been given or sent or, failing such notice, on the day of the meeting;

(b) the record date used to determine which shareholders are entitled to vote during meetings of shareholders shall be fixed on the day of such meeting; and

(c) the record date used to determine which shareholders are entitled to receive financial statements of the Corporation shall be fixed at the close of business of the day the directors adopt a resolution to that effect.

8. Waiver of notice. A shareholder or any other person entitled to be summoned to a meeting of shareholders may waiver a notice of meeting prior to, during or after such meeting is held. The mere presence of a shareholder shall constitute a waiver, unless he is present for the express purpose of opposing the meeting on the grounds that it was irregularly convened.

9. Chairman. The Chairman of the Board of Directors or, failing which, the President of the Corporation or any other person appointed for such purpose by the Board of Directors, shall preside at meetings of shareholders.

10. Quorum. A quorum of shareholders shall exist at an annual or special meeting of shareholders, regardless of the number of persons physically present at the meeting, if one or more holders of shares conferring not less than 33 1/3% of the total number of votes attached to the aggregate of the shares carrying voting rights at such meeting are present physically or represented in accordance with section 11 hereinbelow.


- 4 -

If a quorum is present at the opening of the meeting, the shareholders present or represented may proceed with the business of the meeting, even if a quorum is not present throughout the meeting.

If a quorum is not present at the opening of the meeting, the shareholders present or represented may adjourn the meeting, provided there is a majority vote to that effect, to another time and place but may not transact any other business.

If a quorum is present at the reconvening of the meeting so adjourned, the meeting may then proceed, failing which, a new meeting shall be convened.

11. Representation at meetings. Shareholders shall be entitled to vote in person or, if a body corporate, by representatives duly authorized by resolution of its directors or its decision-making body. Shareholders shall also be entitled to vote by proxy.

A proxyholder need not be a shareholder of the Corporation and may represent several shareholders. A proxy may be given for all or part of a shareholder's shares.

A proxy shall be valid only at the meeting in respect of which it is given or any adjournment thereof.

A proxy appointing a proxyholder shall be in the form prescribed by the Act and its Regulations.

The Board of Directors may specify, in the notice of meeting of shareholders, a date and time limit for depositing with the Corporation or its agent proxies to be used at the meeting; such date and time limits shall not precede the meeting by more than 48 hours, excluding Saturdays and statutory holidays.

The Board of Directors may also permit particulars of proxies for use at or in connection with, any such meeting which have been deposited with the Corporation or its agent at a place other than the place of such meeting to be sent by facsimile to the Secretary of the Corporation prior to such meeting. In such event, such proxies, if otherwise in order, shall be valid and any votes cast in accordance therewith shall be counted.

12. Right to Vote. Subject to the provisions of the Act, each shareholder is entitled to as many votes as his shares in the Corporation carry votes.

13. Decisions by a Majority. Unless otherwise provided in the Act, any question submitted to the meeting of shareholders shall be decided by a simple majority (50% + 1) of validly cast votes.


-5-

14. Casting vote. In the case of a tie vote, the Chairman of the meeting shall have the casting vote.

15. Vote by show of hands. Except where a voice vote or secret ballot has been requested, votes shall be taken by a show of hands. In such a case, shareholders or proxyholders shall vote by raising their hands and the number of votes shall be calculated based on the number of hands raised.

16. Voice vote. If the Chairman of a meeting so orders, or any proxyholder representing at least ten per cent (10%) of the votes attaching to outstanding voting shares so requests (such requests may be withdrawn), and if a vote by secret ballot has not been requested, votes shall be taken by voice vote. In such a case, each shareholder or proxyholder shall orally state his name and that of each shareholder he represents by proxy, the number of votes he represents and how he intends to cast such votes. The number of votes so cast shall determine whether or not a resolution is adopted.

17. Vote by secret ballot. If the Chairman of a meeting so orders, or a shareholder or proxyholder entitled to vote so requests, the vote shall be taken by secret ballot. A request for a vote by secret ballot may be made at any time before the meeting is closed, regardless of whether a vote by show of hands or a voice vote has been previously held or not; such request may also be withdrawn. Each shareholder or proxyholder shall submit to the scrutineers one or several ballots on which he shall have indicated how he intends to cast his votes and, where relevant, his name and the number of votes he has. The result of a secret ballot shall be deemed to be a resolution of the meeting at which the ballot was taken whether or not a vote by show of hands or a voice vote had previously been taken on the same question.

18. Procedure at meetings. The Chairman of any meeting of shareholders shall conduct the procedure thereat in all respects and his decision on all matters, including any question regarding the validity or invalidity of any proxy or the admissibility or inadmissibility of a proposal, shall be conclusive and binding upon all the shareholders.

A declaration by the Chairman at any meeting that a resolution has been carried or not, whether unanimously or by particular majority, shall be conclusive evidence of the fact.

At any time during the meeting, at his own discretion or with the approval of the shareholders given by a simple majority, the Chairman may adjourn a meeting provided he has reasonable grounds to do so, such as when confusion and disorder render the harmonious and orderly conduct of a meeting impossible, and he need not give notice for the reconvening of a meeting so adjourned.

Should the Chairman of the meeting fail to carry out his duties loyalty, the shareholders may, at all times, remove and replace him with another person selected from amongst themselves.

The directors of the Corporation shall be entitled, in such sole capacity, to attend meetings of shareholders and to take the floor thereat.


- 6 -

19. Scrutineers. The Chairman of any meeting of shareholders may appoint scrutineers, who may but need not be directors, officers, employees or shareholders of the Corporation, to act as the Chairman shall direct.

20. Addresses of the shareholders and subsequent transferees of shares. Every shareholder shall furnish the Corporation with a mailing or electronic address to which all corporate notices intended for such shareholder may be sent. Every person who, by operation of the Act, transfer or other means whatsoever, shall become entitled to any share, shall be bound by every notice in respect of such share which, prior to the entry of his name and address on the register, is given to the person whose name appears on the register at the time such notice is given.

21. Signed resolutions. Subject to subsections 110(2) and 168(5) of the Act, a resolution signed by all the shareholders entitled to vote on such resolution shall be as valid as if it had been passed unanimously at a meeting duly convened by such holders. Each duly signed resolution shall be kept with the minutes of the meetings of shareholders.

BOARD OF DIRECTORS

22. Number. The business of the Corporation shall be administered by a Board of Directors composed of a fixed number of directors indicated in the Corporation's Articles. If the Articles provide for a minimum and maximum number of directors, the Board of Directors shall be composed of such fixed number of directors but not less than three (3), as shall be established by resolution passed by the Board of Directors or, failing this, as the shareholders choose to elect within such limits.

23. Qualification. No person shall be qualified for election as a director if he is less than eighteen (18) years of age; if he is of legal age and has been placed under tutorship or curatorship; if he has been declared of unsound mind by a court in Canada or elsewhere; if he has the status of an undischarged bankrupt; or if a court has prohibited him from holding the office of director. Unless otherwise set out in the Articles of the Corporation, a director need not be a shareholder. A majority of the directors shall be Resident Canadians, unless otherwise set out in the Act. At least three (3) of the directors shall be independent and shall not be officers or employees of the Corporation or its subsidiaries. A retiring director, if otherwise qualified, shall be eligible for re-election.

24. Election and term of office. Except for the appointment of a director following a vacancy during a term of office or for the election of one or several additional directors, each director shall be elected by Ordinary Resolution at a general annual meeting of shareholders, subject to the provisions of the Articles of Corporation providing for cumulative voting or the exclusive right of certain classes of shareholders to elect one or several directors. Each director shall be elected either for a fixed term, which shall end no later than at the close of the third annual meeting thereafter, or for an indeterminate term, which shall end at the close of the first annual meeting thereafter. Not


-7-

all directors need have the same term of office. Directors shall remain in office, failing the election of new directors by a meeting of shareholders, until such time as a substitute has been elected.

25. Resignation. A director may resign from his office by sending written notice thereof to the Corporation and need give grounds for such resignation. Said resignation shall take effect on the date of sending or remittance thereof, or on such later date as may be indicated therein.

26. Removal. Unless otherwise provided in the Articles, shareholders may remove a director by Ordinary Resolution at a special meeting. The director who receives notice of his impending removal may, in a written statement, explain to the Corporation the reasons why he opposes his removal, and the Corporation shall forward such written statement to the shareholders entitled to vote in such matter.

A vacancy created by the removal of a director may be filled by the shareholders at the same meeting; in such a case, notice of such meeting shall indicate that an election is to be held should the resolution of removal be carried.

Should the holders of shares of a particular class have the exclusive right to elect a director, such director may only be removed by Ordinary Resolution at a special meeting of such holders.

The removal of a director, as well as his election, shall be at the discretion of the shareholders. A director may be removed at any time and such removal need not be based on any particular grounds, whether serious or not. Neither the Corporation nor the shareholders voting in favour of the removal shall incur any liability toward the director by the mere fact of his removal, even if there be no grounds therefor.

27. Vacancy. The office of a director shall become vacant as of the moment his resignation or removal takes effect; moreover, a vacancy is created when a director is no longer qualified to perform his duties pursuant to section 23 or if he dies.

28. Replacement. If a vacancy occurs on the Board of Directors, the remaining directors may appoint a qualified person to fill such vacancy, for the unexpired term of office. The directors may nonetheless continue to act despite one or several vacancies, provided a quorum exists. Failing a quorum, the remaining directors shall forthwith call a special meeting of shareholders to fill such vacancy, in accordance with section 111 of the Act.

29. Remuneration. The remuneration to be paid to the directors shall be as fixed by resolution of the Board of Directors. Such remuneration shall be in addition to the salary or remuneration received as such from the Corporation by an officer, employee or service provider who is also a director, unless a resolution shall provide otherwise. Directors may also seek reimbursement for traveling and other expenses incurred in connection with their duties.


-8-

30. General powers of the directors. The directors of the Corporation shall manage and administer the Corporation and may make or cause to be made any contract which it may lawfully enter into. The directors shall be invested with all such powers and authority as the Corporation by statute or its Articles is authorized to exercise and do. The directors shall always act by resolution.

The directors may, in particular, acquire or dispose of, either by purchase, sale, lease, exchange, mortgage or otherwise, stocks, interests, warrants, options or other securities, buildings and other movable or immovable property or any right or interest therein; for each transaction, they shall fix the consideration and other conditions.

31. Irregularity. Notwithstanding that it be afterwards discovered that there was some defect in the election of the Board of Directors or the election or appointment of any director or that a director lacks or has lost his qualification, all acts thereof shall be as valid and binding upon the Corporation as if every such board or person had been duly elected or appointed and had been qualified.

32. Use of property or information. No director may mingle the Corporation's property with his own property or use for his own profit or that of a third party any property of the Corporation or any information he obtains by reason of his duties, unless he is expressly and specifically authorized to do so by the shareholders of the Corporation.

33. Conflicts of interest. Each director shall avoid placing himself in a situation of conflict between his personal interest and his obligations as a director of the Corporation.

He shall promptly disclose to the Corporation any interest he has in any enterprise or association that is likely to place him in a situation of conflict of interest, as well as the rights he may enforce thereagainst, indicating, if such be the case, the nature and value thereof. Such disclosure of interest shall be recorded in the minutes of the proceedings of the Board of Directors. A general disclosure shall remain valid until the facts have changed, and a director need not reiterate such declaration for any particular, subsequent transaction.

34. Contracts with the corporation. A director or an officer may, even in performing his duties, enter into material contracts with the Corporation, or be a director, an officer or a holder of a material interest in a body corporate that is a party to such contract. He shall then, in accordance with section 120 of the Act, disclose in writing to the Corporation or request to have entered in the minutes of meetings of directors the nature and extent of his interest in such contract, even if such contract, within the scope of the normal business activity of the Corporation, does not require the approval of either the directors or the shareholders. For the purposes of this by-law, a general notice that the director or officer is a director, an officer or a holder of a material interest in a body corporate and is to be regarded as interested in any contract made with that body corporate, is a sufficient declaration of interest.

A director who is so interested in a contract shall not discuss or vote on such resolution to approve the contract unless the contract is one of the contracts referred to in subsection 120(5) of the


-9-

Act, that is, relating primarily to the remuneration or indemnification of such director, or a contract with an affiliate of the Corporation.

At the request of the President or any director, the interested director shall leave the meeting while the Board of Directors discusses and votes on the contract concerned.

Neither the Corporation nor any of its shareholders may contest the validity of a contract entered into with a director or an officer of the Corporation, or with a body corporate in which such director or officer is a director, an officer or a holder of a material interest, for such sole reason, provided such director or officer has disclosed his interest as aforementioned, the Board of Directors or the Shareholders of the Corporation have approved the contract, and the contract was, at that time, equitable for the Corporation.

MEETINGS OF THE BOARD OF DIRECTORS

35. Calling of meetings. Every year, immediately following the annual general meeting of the shareholders, a meeting of the new directors present shall be held without further notice if they constitute a quorum to elect or appoint the officers of the Corporation and consider, deal with and dispose of any further business.

Meetings of the Board of Directors may be called by or by order of the Chairman of the Board of Directors, if any, the President of the Corporation or two (2) directors and may be held anywhere within or outside Canada. A notice of each meeting, specifying the place, date and time, shall be sent to each director at his residence or workplace. The notice shall be sent no less than five (5) days prior to the date fixed for the meeting by ordinary or registered mail or by facsimile or electronic mail. In the absence of an address for a director, the notice may be sent to the address at which the sender considers that the notice is most likely to reach the director promptly.

The Board of Directors may resolve to hold periodic or fixed meetings of the Board of Directors, with or without notices of meeting, at any place in Canada or elsewhere.

The notice of a meeting of the Board of Directors need not specify the goals or business thereof, with the exception of those matters referred to in subsection 115(3) of the Act, in particular, the declaration of dividends, the issue of securities, the purchase of shares issued by the Corporation, the approval of the annual financial statements, the filling of vacancies on the Board of Directors or in the office of Auditor and the adoption, amendment or repealing of by-laws.

Any director may waive in writing a notice of meeting of the Board of Directors prior to, during or after the holding of such meeting. His mere presence at a meeting shall constitute a waiver, unless he is present for the sole purpose of objecting to the holding thereof on the grounds that the manner of calling it was irregular.


-10-

Notice need not be given of the reconvening of an adjourned meeting of directors if the date, time and place of such meeting were announced at the initial meeting.

36. Participation by telephone. Directors may, if all are in agreement, participate in a meeting of the Board of Directors using means permitting all participants to communicate orally amongst themselves, in particular, by telephone. A director participating in the meeting by such means shall be deemed to have attended the meeting. The directors shall then vote by a voice vote, by way of derogation to section 40 hereinbelow.

37. Quorum. A majority of the directors in office shall constitute a quorum for a meeting of the Board of Directors. A quorum shall be present throughout the meeting. Once a quorum exists, the directors may exercise their powers, notwithstanding any vacancy on the board. No business shall be dealt with unless the number of "Resident Canadian" directors prescribed in the Act is present.

38. Meeting chairman and secretary. Meetings of the Board of Directors shall be chaired by the Chairman of the Board of Directors, if any, or, failing him, by the President of the Corporation or, failing him, by a Vice-President designated for such purpose by the President. The Secretary of the Corporation shall act as Secretary of the meetings. The directors present at a meeting may nevertheless appoint any other persons as Chairman or Secretary of such meetings.

39. Procedure. The Chairman of the meeting shall ensure that the meeting is conducted smoothly and submit to the Board of Directors the motions on which a vote is to be taken and shall generally conduct the procedure thereat in all respects, in which regard his decision shall be final and binding on all directors. Should the meeting Chairman fail to submit a motion, any director may submit it himself before the meeting is adjourned or closed and, if such motion lies within the competence of the Board of Directors, the Board of Directors shall consider it. For such purpose, the agenda of each meeting of the Board of Directors shall be deemed to include a period for the submission of motions by the directors. Should the Chairman of the meeting fail to carry out his duties loyally, the directors may remove him at any time and replace him by another person.

40. Voting. Each director shall be entitled to one vote, and all matters shall be decided by the majority of votes cast. The vote shall be taken by a show of hands unless the Chairman of the meeting or a director requests a ballot, in which case the vote shall be taken by ballot. If the vote is taken by ballot, the meeting Secretary shall act as Scrutineer and count the ballots. The fact of having voted by ballot shall not deprive a director of the right to express his dissent in respect of the resolution concerned and to cause such dissent to be entered. Voting by proxy shall not be permitted, and the Chairman of the meeting shall have no casting vote in the case of an equality of votes.

41. Signed resolution. A written resolution, signed by all the directors, shall be valid and have the same effect as though it were adopted at a meeting of the Board of Directors duly called and held. Each signed resolution shall be inserted in the minute book of the Corporation, in order of its date, in the same manner as minutes.

The Notice of Redemption shall inform the holders of Preferred Shares Series 1 of the redemption of their Preferred Shares Series 1 on the Redemption Date and shall be given no less than 5 days prior to the Redemption Date.

3.6 CONVERSION AT OPTION OF CORPORATION

On November 30, 2000 (the "Conversion Date"), the Corporation shall, if it has elected not to redeem the Preferred Shares Series 1, pursuant to Section 3.5 above, convert all outstanding Preferred Shares Series 1 into Subordinate Voting Shares. The number of Subordinate Voting Shares to which is entitled a holder of Preferred Shares Series 1 shall be equal to the result obtained by dividing the Aggregate Redemption Price of the Preferred Shares Series 1 held by such holder by the Conversion Price. No fractional Subordinate Voting Shares shall be issued upon the conversion of the Preferred Shares Series 1. In lieu of any fractional shares to which the holder would otherwise be entitled, the Corporation shall pay a cash amount equal to such fraction multiplied by the then effective Conversion Price. On the Conversion Date, the Preferred Shares Series 1 converted shall be cancelled automatically and their holders shall have the right to receive, upon delivery to the Corporation at its principal office during its usual business hours of the certificate or certificates representing the Preferred Shares Series 1 so converted duly endorsed, a certificate or certificates representing the number of Subordinate Voting Shares resulting from the conversion of the Preferred Shares Series 1 together with the cash amount payable as a result of conversion into fractional Subordinate Voting Shares (less any taxes which must be deducted or withheld in respect thereof). Payment of cash amounts shall be made by cheque. The Corporation shall be entitled to deposit the certificates representing the number of Subordinate Voting Shares resulting from the conversion of the Preferred Shares Series 1 together with the cash amounts payable as a result of conversion into fractional Subordinate Voting Shares (less any taxes which must be deducted or withheld in respect thereof) in one or more trust companies within Canada who shall have been named in a written notice sent by mail by the Corporation to the last known address of each registered holder of Preferred Shares Series 1. Such deposits shall be made in one or more special trust accounts for the benefit of holders of Preferred Shares Series 1 converted, and the certificates representing the Subordinate Voting Shares to which they are entitled and the cash amounts owing to them shall be remitted by such trust companies upon remittance of the certificate or certificates representing the Preferred Shares Series 1 so converted duly endorsed. Once these deposits have been made, the Preferred Shares Series 1 shall be deemed to have been converted on the Conversion Date. After the Corporation has effected a deposit in the aforementioned manner with respect to any of the Preferred Shares Series 1, as of the Conversion Date, holders of such shares shall not have any further rights as holders of Preferred Shares Series 1 with respect to such shares; any accrued interest on the cash amount deposits shall belong to the Corporation.


3.7 DISTRIBUTION RIGHTS

In the event of the liquidation, dissolution or winding-up of the Corporation, whether voluntary or involuntary, the holders of the Preferred Shares Series 1 shall be entitled to receive, before any distribution or payment of any part of the assets of the Corporation among the holders of Multiple Voting Shares and Subordinate Voting Shares, an amount equal to the Redemption Price of their shares and no more.

3.8 VETO

No class of shares of an Equal Rank or of a Superior Rank with the Preferred Shares Series 1 may be created, and the provisions relating to the Preferred Shares Series 1 or relating to other classes of shares may not be modified so as to confer on such shares rights or privileges that are of Equal Rank or of Superior Rank to those attached to the Preferred Shares Series 1, unless such creation or modification has been approved by a special resolution of the holders of Preferred Shares Series 1 at a special meeting of such holders convened for such purpose.

3.9 INTERPRETATION

3.9.1  All amounts set forth in these presents are expressed in
       Canadian dollars and all amounts required to be converted into
       Canadian dollars shall be deemed to be converted into or from
       Canadian dollars at the noon buying rate of the Federal Reserve
       Bank of New York on the date as of which such conversion is
       determined.

3.9.2  Notwithstanding any provision to the contrary set forth in
       these presents, the payment of any sum of money may be made by
       electronic transfer or by any other means which the Board of
       Directors may approve, instead of being made by cheque. In such
       an event, the payment of sums of money to holders of Preferred
       Shares Series 1 shall be deemed to constitute payment and shall
       release the Corporation from all its obligations with respect
       to the payment of such sums, up to the amount represented
       thereby, unless the payment is not honoured by the Corporation.

                         (hereinafter called the "TRUSTEE")

WHEREAS the Corporation has an authorized share capital consisting of an unlimited number of subordinate voting shares (the "SUBORDINATE VOTING SHARES"), an unlimited number of multiple voting shares (the "MULTIPLE VOTING SHARES") (the Subordinate Voting Shares and the Multiple Voting Shares are collectively referred to herein as the "EQUITY SHARES") and an unlimited number of Preferred Shares issuable in series;

WHEREAS the Corporation proposes to issue and sell 6,000,000 Subordinate Voting Shares pursuant to a prospectus dated __, 2000 (900,000 additional Subordinate Voting Shares if the over-allotment (the "Over-Allotment") granted by the Corporation to Merrill Lynch, Pierce, Fenner & Smith Incorporated, RBC Dominion Securities Inc., Wit SoundView Corporation and CIBC World Markets Inc. is exercised in full (the "OFFERING");

WHEREAS on the closing date of this Offering (the "Closing Date") 38,000,000 Multiple Voting Shares, 6,709,605 Subordinate Voting Shares (7,609,605 Subordinate Voting Shares if the Over-Allotment option is exercised in full) and 800,000 Preferred Shares Series 1 will be issued and outstanding;

WHEREAS the Shareholders and the Corporation have agreed to enter into this Agreement in order to secure the listing of the Subordinate Voting Shares of the Corporation on The Toronto Stock Exchange and derive the benefits of such listings, and for the purpose of ensuring that the holders of the Subordinate Voting Shares will not be deprived of any rights under applicable take-over bid legislation to which they would have been entitled in the event of a take-over bid if the Multiple Voting Shares and the Subordinate Voting Shares were a single class of shares;

WHEREAS the Shareholders and the Corporation wish to constitute the Trustee as a trustee for the holders of the Subordinate Voting Shares all as contemplated hereby in order that such holders, through the Trustee, will benefit from the covenants of the Shareholders and the Corporation as contained in this Agreement;

WHEREAS, for the purpose of this Agreement, "LAMONDE FAMILY " means collectively (i) Germain Lamonde, (ii) his spouse, in fact or in law, (iii) any lineal descendant of Germain Lamonde, born or to be born, (iv) any trust constituted primarily for the benefit of Germain Lamonde, his spouse, in fact or in law, or any of his descendants, born or to be born, and (v) any corporation where 90% of the votes attaching to all outstanding shares and at least 50% of all outstanding shares are controlled by any one or more of such persons or trusts.

NOW THEREFORE, THIS AGREEMENT WITNESSETH that in consideration of the promises and agreements herein contained and for other good and valuable consideration, the receipt of which is hereby acknowledged, the parties hereto agree as follows:

1. Subject to the other provisions of this Agreement, the Shareholders being the holders of all the Multiple Voting Shares (the "MV SHAREHOLDERS" or, as the case may be, a "MV SHAREHOLDER") shall not sell nor dispose of, directly or indirectly, any Multiple Voting Shares pursuant to a take-over bid, as defined by applicable securities legislation, under circumstances in which securities legislation would have required the same offer or a follow-up offer to be made to all holders of Subordinate Voting Shares if the sale had been of Subordinate Voting Shares rather than Multiple Voting Shares, but otherwise on the same terms. For this purpose, it shall be assumed that the offer that would have resulted in such sale of Subordinate Voting Shares would have constituted a take-over bid under applicable securities legislation, regardless or whether this actually would have been the case. Should it be necessary to determine the value of Multiple Voting Shares to ascertain the applicability of any


-3-

exemption from take-over bid requirements for the purposes of the foregoing, the Multiple Voting Shares shall be deemed to have the same value as that which would be assigned by applicable securities legislation to the Subordinate Voting Shares under similar circumstances.

2. Section 1 shall not apply to prevent any sale or other disposition by any MV Shareholder of Multiple Voting Shares, if:

(a) such sale or other disposition is made pursuant to an offer to purchase part only of the Multiple Voting Shares made to all holders of Multiple Voting Shares, and an offer all the terms of which are at least as favourable as the terms of the offer to purchase the Multiple Voting Shares (in terms of price per share, percentage of outstanding shares to be taken up exclusive of shares owned immediately prior to the offer by the offeror, or associates or affiliates of the offeror, and in all other material respects) is made concurrently to all holders of Subordinate Voting Shares to purchase Subordinate Voting Shares, which offer is unconditional (other than the right not to take up and pay for shares tendered if no shares are purchased pursuant to the offer for Multiple Voting Shares); or

(b) there is a concurrent unconditional offer, all terms of which are as favourable as the terms of the offer to purchase the Multiple Voting Shares, to purchase all of the Subordinate Voting Shares at a price per share at least as high as the highest price per share offered pursuant to the said sale or other disposition of the Multiple Voting Shares referred to in (a) above; or

(c) such sale or disposition is a direct or indirect sale or other disposition of shares of the Corporation, provided that (i) the sale or other disposition is effected within the Lamonde Family at a price which is within the margin prescribed by the Securities Act (Quebec),
(ii) the transferee is not a party to any agreement under which any other person would directly or indirectly participate in the beneficial ownership of, control or direction over more than 50% of the votes attaching to the Equity Shares held by such transferee,
(iii) the sale is otherwise made in accordance with applicable law,
(iv) the prior written consent of the Trustee as contemplated by
Section 4 of this Agreement has been obtained, and (v) the transferee, if not already a party to this Agreement, becomes a party to this Agreement.

For the purposes of paragraphs (a) and (b) of this Section 2, the varying of any term of an offer shall be deemed to constitute the making of a new offer.

3. Without restricting the generality of the foregoing and in addition to any other provisions herein of similar effect, the MV Shareholders agree that the Multiple Voting Shares shall be automatically converted into Subordinate Voting Shares upon the occurrence of any of the following circumstances, namely: (A) members of the Lamonde Family (as defined in the preamble hereof) do not beneficially own, directly or indirectly, in any manner, a number of Equity Shares representing either (i) more than 50% of the votes attaching to all issued and outstanding Equity Shares or (ii) 60% of the total number of Multiple Voting Shares held by them on the closing date of this Offering (or 22,800,000 Multiple Voting Shares) or (B) Germain Lamonde no longer occupies the position of either Chairman of the Board or

Chief


-4-

Executive Officer of the Corporation, for any reason, including voluntary or forced retirement, death or incapacity (the "Occurrence"), unless such situation is remedied within 60 days from the Occurrence or, if the situation which gave rise to such Occurrence is the incapacity of Germain Lamonde, within 1 year from the Occurrence. The Trustee is hereby irrevocably instructed to convert the Multiple Voting Shares into Subordinate Voting Shares 60 days after the Occurrence, provided the situation which gave rise to such Occurrence has not been remedied within such 60-day period or, as the case may be, if the situation that gave rise to such Occurrence is the incapacity of Germain Lamonde, 1 year after the occurrence of such incapacity, provided the incapacity of Germain Lamonde has not ceased within such 1-year period.

In addition, if at any time, the Lamonde Family or any of its members sells or otherwise transfer Multiple Voting Shares to a party who is not a member of the Lamonde Family, such transferred shares shall be automatically converted on the date of such sale or transfer into Subordinate Voting Shares and the Trustee shall automatically convert those shares into Subordinate Voting Shares unless a certificate signed by the transferor and transferee confirming that the transferee is a member of the Lamonde Family is provided to the Trustee.

4. Notwithstanding any other provision contained herein, the prior written consent of the Trustee shall be required in connection with any sale or other disposition of Multiple Voting Shares, whether direct or indirect, by any MV Shareholder. Such consent shall be given no later than the next Business Day of receipt by the Trustee of evidence satisfactory to it, acting reasonably, to the effect that the sale or disposition is not in contravention of this Agreement. For the purposes of the foregoing, the Trustee shall be entitled to consider a legal opinion to be satisfactory evidence although no such opinion is necessarily required. The Trustee also has the right to require from time to time evidence satisfactory to it, acting reasonably, as to the number of Equity Shares beneficially owned directly or indirectly by the Lamonde Family or any MV Shareholder. For the purposes of this Agreement, "Business Days" means a day, other than a Saturday, Sunday or any other day on which the principal banks located in Quebec City are not open for business during normal banking hours. No consent shall be given in respect of any sale or disposition unless the Trustee receives the consent of the person or company requiring the shares to be bound hereby as an MV Shareholder.

5. Each MV Shareholder shall use its best efforts to prevent any person or company it controls from carrying out any direct or indirect sale or other disposition in contravention of the foregoing in respect of any Multiple Voting Shares owned from time to time by such MV Shareholder, or any person or company controlled, directly or indirectly by such MV Shareholder, regardless of whether such person or company is a party to this Agreement.

6. For greater certainty, any direct or indirect sale or other disposition which would result in the direct or indirect acquisition of beneficial ownership of Multiple Voting Shares or Subordinate Voting Shares, or in the direct or indirect acquisition of control or direction over such shares, shall be construed to be a sale or disposition of such Multiple Voting Shares or Subordinate Voting Shares, as the case may be, for the purposes of the foregoing.

7. No MV Shareholder or any corporation which it controls shall directly or indirectly sell or dispose of any Multiple Voting Shares unless the sale or disposition is conditional upon the


-5-

person, trust or company acquiring such Multiple Voting Shares becoming a party to this Agreement as a MV Shareholder.

8. Notwithstanding any other provision contained herein, the restrictions of the preceding provisions of this Agreement, subject to Section 11, shall not apply to the exercise by the holder of Multiple Voting Shares of any right of conversion into Subordinate Voting Shares attaching to the Multiple Voting Shares and the subsequent sale or disposition of the Subordinate Voting Shares issued upon such conversion.

9. Nothing in this Agreement shall prevent an MV Shareholder from granting, from time to time, directly or indirectly, a security interest, by way of pledge, hypothecation or otherwise, whether directly or indirectly, in Multiple Voting Shares to any financial institution with which it deals at arm's length (within the meaning of the Income Tax Act (Canada)) in connection with a bona fide borrowing provided that concurrent with the pledge, hypothecation or other granting of the security interest, the financial institution agrees in writing to become a party to and abide by the terms of this Agreement as if such financial institution were a MV Shareholder until such time as the pledge, hypothecation or other security interest has been released or the Multiple Voting Shares which were subject thereto have been sold or disposed of in accordance with the terms of this Agreement.

10. The Shareholders hereby agree to place on deposit with the Trustee, contemporaneously with the issuance of Subordinate Voting Shares to the public pursuant to the final prospectus of the Corporation dated __ , 2000, 38,000,000 Multiple Voting Shares which are represented by the certificates referred to in Schedule "A" hereto and hereby undertake and agree to deliver the share certificates representing such shares (including any replacement securities or certificates if and when such are issued or allotted) to the Trustee for safekeeping and to assure compliance with the terms and conditions hereof. It is understood, however, that the Trustee shall release from deposit such number of Multiple Voting Shares as are covered by any consent granted in accordance with the provisions of Section 4 save and except for transfers among members of the Lamonde Family.

11. If any person or company carries out an indirect sale or other disposition contemplated in this Agreement in contravention of the terms hereof, the person, trust, or company acquiring such shares shall not thereafter do any of the following with respect to any of the Multiple Voting Shares so sold or disposed or to those Subordinate Voting Shares resulting from the conversion thereof: (a) directly or indirectly sell or dispose of them without the prior written consent of the Trustee; or (b) exercise any voting rights attaching to them except in accordance with the written instructions of the Trustee. The Trustee may attach conditions to any consent the Trustee gives in exercising its rights hereunder. The Trustee shall exercise such rights in a manner that the Trustee considers to be:
(i) in the best interests of the holders of the Subordinate Voting Shares, other than the Shareholders or any MV Shareholder who, in the opinion of the Trustee, participated directly or indirectly in the transaction that triggered the operation of this Section 11, (ii) in accordance with applicable securities legislation, and (iii) consistent with the intentions of the Shareholders and the Corporation in entering into this Agreement as such intentions are set out in the preamble to this Agreement. Notwithstanding a sale or disposition of shares which constitutes an indirect sale or disposition of Multiple Voting Shares in contravention to this Agreement, the Shareholders shall not, although remaining bound by the restrictions and prohibitions of this Agreement,


-6-

have any liability for damages hereunder in respect of such sale or disposition, provided that the Shareholders are otherwise in compliance with all other provisions of this Agreement.

12. The Lamonde Family or any of its members shall send to the Trustee within 30 days of the end of each financial year a certificate signed by each member of the Lamonde Family confirming that (A) members of the Lamonde Family do beneficially own, directly or indirectly, in any manner, a number of Equity Shares representing either (i) more than 50% of the votes attaching to all issued and outstanding Equity Shares or (ii) 60 % of the total number of Multiple Voting Shares held by them on the closing date of the Offering (or 22,800,000 Multiple Voting Shares) and (B) Germain Lamonde still occupies the position of either Chairman of the Board or Chief Executive Officer of the Corporation. In addition, if and whenever the Trustee has reasonable cause to believe that any MV Shareholders or the Corporation may have breached, or may intend to breach, any provision of this Agreement, the Trustee shall make reasonable enquiry to determine whether such a breach has occurred or is intended, and if the Trustee thereupon determines that such is the case the Trustee shall forthwith deliver to the Corporation a notice stating that the Trustee has made such determination. The Trustee shall thereupon be entitled to take and, subject to Section 14, shall take such action as the Trustee considers necessary to enforce its rights under this Agreement on behalf of the holders of the Subordinate Voting Shares. Any action which the Trustee is entitled to take in such circumstances includes, without limitation, a refusal to consent to any sale or disposition of Multiple Voting Shares.

13. Subject to Section 14, if and whenever holders of not less than 10% (excluding any members of the Lamonde Family or any holders of Multiple Voting Shares) of the then outstanding Subordinate Voting Shares determine that any one of the MV Shareholders or the Corporation has breached, or intends to breach, any provision of this Agreement, such holders may require the Trustee to take action in connection with such failure by delivering to the Trustee a requisition in writing signed in one or more counterparts by such holders and setting forth the nature of the breach and requesting the Trustee to take action as provided for in this Agreement, and upon receipt by the Trustee of such a requisition the Trustee shall forthwith take such action or any other action that the Trustee considers necessary to enforce its rights under this Agreement on behalf of the holders of the Subordinate Voting Shares.

14. The obligation of the Trustee to take any action on behalf of the holders of the Subordinate Voting Shares shall be conditional upon the Trustee receiving from the Corporation or from one or more holders of Subordinate Voting Shares such indemnification as the Trustee may reasonably require in respect of any costs or expenses which it may incur in connection with any such action. The Corporation shall provide such indemnification to the Trustee if the Trustee has delivered to the Corporation the notice referred to in Section 12.

15. No holder of Subordinate Voting Shares (excluding any members of the Lamonde Family or any holders of Multiple Voting Shares) shall have the right, other than through the Trustee, to institute any action or proceeding or to exercise any other remedy for the purpose of enforcing any rights arising from this Agreement unless holders of Subordinate Voting Shares shall have requested in the manner specified in Section 13 that the Trustee act and shall have provided reasonable indemnity to the Trustee and the Trustee shall have failed to so act within 30 days after the provision of such indemnity. In such case, any holder of Subordinate Voting Shares shall be entitled to take proceedings in any court of competent


- 7 -

jurisdiction such as the Trustee might have taken. In such circumstances, the Corporation shall reimburse the reasonable costs of any action that may be taken in good faith by the holders of Subordinate Voting Shares in accordance with the provisions hereof.

16. The Corporation shall do all things necessary to facilitate the due performance of this Agreement including the fulfillment by the Shareholders of their obligations hereunder.

17. The Trustee may resign and be discharged from all further duties and liabilities hereunder, subject to Section 19, after giving 30 days' written notice to the Corporation and the Shareholders or such shorter notice as the Corporation and the Shareholders may accept as sufficient.

18. The Corporation may terminate the Trustee's mandate pursuant to this Agreement, after giving 30 days' written notice to the Trustee, should:

(a) any company into or with which the Trustee may be merged or consolidated or amalgamated, or any company succeeding to the trust business of the Trustee be unacceptable to the Corporation, acting reasonably; or

(b) the financial situation of the Trustee is such that, in the opinion of the Corporation, acting reasonably, it jeopardizes the Trustee's capability to perform its obligations under this Agreement; or

(c) the fees and expenses of the Trustee are, in the opinion of the Corporation, acting reasonably, not within the general practice of the industry.

In the event that the office of trustee becomes vacant, the Corporation shall forthwith appoint a new trustee which shall be a company licensed or authorized to carry on the business of a trust company in the Province of Quebec; failing such appointment, the Shareholders, the Trustee or any holder of Subordinate Voting Shares may apply to a judge of the Quebec Superior Court for the appointment of a new trustee. Upon any new appointment, the new trustee shall be vested with the same powers, rights, duties and responsibilities as it had been originally named herein as the trustee, but there shall be immediately executed, at the expense of the Corporation, all such instruments as may be, in the opinion of counsel to the Corporation, necessary or desirable to assure such vesting. Any resignation or termination of the Trustee shall not become effective until the successor party shall have executed an appropriate instrument accepting the appointment as the new trustee. Notwithstanding such resignation or termination, the Trustee shall continue to be indemnified in accordance with Section 19.

19.

(a) Each of the MV Shareholders and the Corporation, jointly but not jointly and severally, agree to indemnify and save harmless the Trustee from and against all claims, liabilities, losses, penalties, actions, suits, costs, expenses and disbursements (including legal and advisory fees and expenses) made against it by anyone, in the absence of negligence or fraud by the Trustee, its officers, directors and employees, by reason of the Trustee's compliance in good faith with the terms hereof. It is


- 8 -

understood that, as between the MV Shareholders and the Corporation, the party in default or alleged to be in default hereunder shall be responsible for such indemnification if it arises from its own default or alleged default. It is understood and agreed that this indemnification shall survive the termination or discharge of this agreement or resignation of the Trustee.

(b) The Trustee may employ or retain counsel, auditors, accountants, or other experts or advisors, whose qualifications give authority to any opinion or report made by them as it may reasonably require for the purpose of discharging its duties hereunder and shall not be responsible for any misconduct on the part of any of them. The Trustee may, if it is acting in good faith, rely on the accuracy of any such opinion or report.

(c) The Trustee shall have no responsibility, if it is acting in good faith, for the genuineness or validity or any securities, documents or other things deposited with it. In the exercise of its rights, duties and obligations hereunder, the Trustee may, if it is acting in good faith, rely as to the truth of the statements and the accuracy of the opinions expressed in any certificates or other documents provided to it.

20. The Corporation shall pay the reasonable fees and expenses of the Trustee in connection with the performance of the Trustee's obligations hereunder, including the reasonable fees and disbursements of counsel or other experts employed by the Trustee, but this Section 20 shall not require the Corporation to pay any fees or expenses in connection with any action taken by the Trustee pursuant to Section 12 if the Trustee has not delivered to the Corporation the notice referred to in Section 12 in respect of such action.

21. The Trustee hereby accepts the appointment as depositary and trustee for the holders from time to time of the Subordinate Voting Shares upon the terms and conditions herein set forth. Subject to the limitations contained herein, the Trustee shall act as a depositary and, in its capacity of trustee, shall be charged with simple administration in accordance with the provisions of the Civil Code of Quebec, it being understood that the Trustee shall not have, except as provided herein, any rights as a shareholder with respect to the Multiple Voting Shares such as, the right to vote and to receive dividend on such shares.

22. This Agreement shall not be amended, and no provision thereof shall be waived, except with (i) the consent of any stock exchange upon which the Subordinate Voting Shares are quoted and/or listed and any other applicable securities regulatory authorities and (ii) the approval of at least two-thirds of the votes cast by holders of Subordinate Voting Shares present or represented at a meeting duly called for the purpose of considering such amendment or waiver, and of at least one simple majority of the votes cast by holders of Subordinate Voting Shares, excluding any of the MV Shareholders and their respective affiliates and any persons who have an agreement to purchase Multiple Voting Shares on terms which would constitute a sale or disposition subject to Section 1, other than as permitted herein.

23. The provisions of this Agreement shall only come into effect contemporaneously with the issuance of Subordinate Voting Shares to the public pursuant to the final prospectus of the Corporation dated ___, 2000.

24. For purposes only of this Agreement and applicable securities legislation, all parties hereto shall be deemed to be residents of the Province of Quebec.

25. No provision of this Agreement shall limit the rights of any holders of Subordinate Voting Shares under applicable law.

Re: EXFO Electro-Optical Engineering Inc./ EXFO Ingenierie Electro-Optique inc. Registration Statement on Form F-1

Ladies and Gentlemen:

We have acted as Canadian counsel to the Company in connection with the authorization and issuance by EXFO of up to 6,000,000 subordinate voting shares of the Company together with an additional 900,000 subordinate voting shares, if and to the extent the underwriters exercise an over-allotment option granted by the Company (together, "Shares"), and the preparation and filing of a registration statement on Form F-1 ("Registration Statement") under the Securities Act of 1933, as amended ("Securities Act"), which the Company is filing with the Securities and Exchange Commission with respect to the Shares.

We have examined the Registration Statement and such documents and records of the Company and other documents as we have deemed necessary for the purpose of this opinion. We have assumed, with your permission and without independent investigation, (i) the genuineness of all signatures, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as photostatic or facsimile copies, and the authenticity of the originals of such copies, (ii) the accuracy of the factual representations made to us by officers and other representatives of the Company, whether evidenced by certificates or otherwise, (iii) the identity and capacity of all individuals acting or purporting to act as public officials, and (iv) that all actions contemplated by the Registration Statement have been and will be carried out only in the manner described therein.

Based upon the foregoing, we are of the opinion that upon the happening of the following events:

(a) the filing of the Registration Statement and any amendments thereto and the Registration Statement becoming effective; and

(b) the sale of the Shares and the receipt by the Company of an amount equal to the full consideration for the Shares as contemplated by the Registration Statement; and

(c) the due issuance by the Company and registration by its registrar of the Shares:

the Shares will be duly authorized, validly issued, fully paid and non-assessable.

In rendering this opinion we express no opinion as to the laws of any jurisdiction other than the laws of the Province of Quebec and the federal laws of Canada applicable therein.

We hereby consent to the filing of this opinion as an exhibit to the Registration Statement and to the reference to our firm in the Prospectus made part of the Registration Statement under the heading "Legal Matters". In giving such consent, we do not admit that we are "Experts" under the Securities Act.

                    montant de cette perte et l'Emprunteur doit sans delai payer
                    ce montant a l'Agent pour le Preteur concerne;

         15.8.3.    Lorsqu'une Avance porte interet a Taux de Base plus la
                    majoration applicable s'il y a lieu en vertu de l'une ou
                    l'autre des dispositions de cette convention, l'Emprunteur
                    reconnait et convient, que malgre toutes dispositions

                    par l'Emprunteur sont toujours le plus eleve du Taux de Base

CONVENTION RELATIVE AUX GARANTIES DONNEES PAR LE CLIENT

En consideration de fait que la Banque Nationale de Paris (Canada) la <<banque>>) consent a faire affaire avec le soussigne EXFO INGENIERIE ELECTRO-OPTIQUE INC. (le <<client>>), le client convient comme suit:

1. Le client convient avec la banque que les dispositions qui suivent s'appliquent aux garanties consenties ou a etre consenties a la banque par le client en vertu de la Loi sur les banques, et, pour autant que les lois applicables le permettent, a toutes les autres guaranties que le client a consenti ou pourra consentir a la banque.

2. A defaut du paiement par le client de toute somme due par lui a la banque, ou si le client est autrement en defaut envers la banque ou s'il devient insolvable, la banque, sans toutefois y etre tenue, est autorisee a realiser en totalite ou en partie les garanties donnees par le client, a prendre possession et a vendre, en totalite ou en partie, les biens affectes par ces garanties (les <<biens>>). La vente pourra etre faite de la maniere, a l'epoque et a l'endroit que la banque choisira, et ce, sans avis au client (autre qu'un avis requis par la loi), sans formalite et sans obligation d'annoncer ou de vendre aux encheres publiques. La banque aura le choix de l'imputation du produit de la realisation de garanties, et elle pourra deduire de ce produit le montant des frais de realisation des garanties.

3. Dans le cas de vente des biens par le client, en tout ou en partie, le produit de toute vente, y compris les especes, effets de commerce, instruments de paiement et titres remis en contrepartie, de meme que les creances contre les acheteurs appartiendront a la banque a qui ils devront etre verses ou remis et, jusqu'a ce versement ou cette remise, le client les detiendra a titre de fiduciaire et de depositaire pour la banque. L'execution par le client d'une cession ou d'une hypotheque de creances sera censee resulter de la presente convention et ne constituera pas une reconnaissance de la part de la banque que le client a des droits sur ces creances.

4. Si, afin de permettre au client d'entrer en possession des biens, la banque lui remet une des garanties qu'elle detient, il recevra cette garantie et les biens qu'elle vise a titre de fiduciaire et de depositaire pour la banque.

5. Le client doit faire assurer les biens pour leur pleine valeur assurable contre l'incendie et le voi et contre tout autre risque qu'un administrateur prudent protegerait par assurance. La banque est par les presentes designee beneficiaire des indemnites payables en vertu des polices concernant les biens, et le client fera inscrire cette designation sur les polices. Le client remettra a la banque une copie de chaque police; au moins quinze (15) jours avant l'echeance d'une police, le client remettra a la banque une preuve de son renouvellement. A defaut par le client de se conformer a ce qui precede, la banque, sans toutefois y etre tenue, peut faire assurer les biens pour le montant qu'elle jugera a propos, et dans ce cas, les primes payees par la banque seront reputees etre une avance faite au client et remboursable a demande, avec interet au taux preferentiel de la banque, plus trois pour cent (3%).

6. Le client doit acquitter a echeance toute creance pouvant conferer sur les biens des droits prioritaires aux droits de la banque et il doit en fournir la preuve a la banque. La banque peut de temps a autre, aux frais du client, inspecter les biens et les registres comptables et factures du client, et a cette fin, le client doit donner a la banque acces aux lieux ou se trouvent les biens ainsi que ces registres et factures. A la demande de la banque, le client doit, mensuellement, remettre a la banque une declaration de la valeur des biens et fournir a la banque tous autres renseignements demandes par celle-ci au sujet des biens.


CO-108-FQ-0597 Page 1 de 2

CONVENTION RELATIVE AUX GARANTIES DONNEES PAR LE CLIENT

7. Dans le but de realiser les garanties consenties par le client, la banque peut, sans, mise en demeure, entrer dans les lieux occupes par le client en rapport avec les biens; elle peut les occuper, a l'exclusion de toute autre personne, y compris le client, et s'en servir sans frais jusqu'a ce qu'elle ait dispose des biens. Elle peut nommer un sequestre ou agent aux fins d'exercer les droits accordes a la banque dans cette convention. Ce sequestre ou agent a de plus le droit d'agir au nom du client, et aux frais de celui-ci, pour completer la fabrication des biens, pour les expedier et pour faire toutes choses necessaires a cette fin.

8. Le client devra signer ou endosser tout document qui, de l'avis de la banque, devrait etre signe ou endosse pour executer la presente convention ou pour completer le titre de la banque sur les biens ou sur leur produit. A cette fin, le client nomme la banque, avec pouvoir de substitution, son mandataire aux fins de signer ou endosser en son nom tout tel document. Ce mandat subsistera nonobstant le deces ou le changement d'etat du client et il ne pourra etre revoque tant que le client restera endette envers la banque.

9. La banque pourra faire des compromis, transiger ou donner quittance relativement aux garanties, aux biens ou a leur produit.

10. Dans cette convention, les mots <<frais de realisation des garanties>> s'entendent notamment de tous les frais, depenses et honoraires payes ou encourus par la banque pour prendre possession des biens, en faire l'inventaire, les proteger, les conserver, en completer la fabrication et les vendre, ainsi que pour percevoir les creances resultant de la vente de ces biens.

11. Les droits accordes a la banque dans cette convention s'ajoutent aux droits qui lui sont accordes par la loi et par toute autre convention. Ces droits s'etendront a tout successeur de la banque, y compris a une entite ayant succede a la Banque par suite d'une fusion ou autrement.

12. Tout avis au client peut lui etre donne par courrier ordinaire a sa derniere adresse connue de la banque.

ANNEXE A

REPARTITION DES COTISATIONS PATRONALES

Les cotisations patronales sont subdivisees en trois categories; les cotisations de base, les cotisations complementaires et les cotisations supplementaires.

Aucune cotisation de base ou complementaire n'est due a un employe qui ne verse pas une cotisation minimale, dite de base, au REER collectif de Ingenierie electro-optique EXFO qui est fixee a 2 % de son salaire de base. Si un participant retire une partie de ses sommes accumulees a titre de cotisations de base au REER, les cotisations patronales futures, lui etant allouees au RPDB, seront reduites du montant retire. Cette penalite ne s'applique pas sur un retrait effectue sur le solde de ses cotisations facultatives au REER. L'employeur pourra deroger a cette regle si l'employe justifie les causes de son retrait et que celles-ci satisfont l'employeur.

Par exemple, la participation a un regime d'accession a la propriete n'occasionnera pas la penalite citee precedemment.

LES COTISATIONS DE BASE

       CATEGORIE                       TAUX DE COTISATION
       ---------                       ------------------
Employe non-syndique             1 % du salaire de base courant
                                  et des commissions courantes

Chef de groupe et directeur      1 % du salaire de base courant
                                  et des commissions courantes

Les cotisations de base sont remises au fiduciaire au moins mensuellement. Le salaire de base doit etre determine au prorata du nombre de paies par annee.


LES COTISATIONS COMPLEMENTAIRES

Les cotisations sont basees sur le degre de realisation des objectifs de la compagnie et du rendement du participant pour une annee donnee. Le taux de cotisations sera determine en temps et lieu par l'employeur et pourra varier selon la categorie d'emploi.

Le taux sera en fonction du salaire de base courant et des commissions ajustees du participant a la date du versement, multiplie par la participation active au regime au cours des 12 derniers mois finissant le dernier jour de l'exercice financier de la compagnie divisee par 12.

Les cotisations complementaires sont remises au fiduciaire une fois l'an, soit dans les 120 jours du dernier exercice financier de la compagnie, aux participants qui sont a l'emploi de la compagnie a la date du depot.

LES COTISATIONS SUPPLEMENTAIRES

L'employeur peut verser une cotisation discretionnaire dite supplementaire a n'importe quel participant. Toutefois, cette cotisation ne doit pas faire en sorte que les cotisations patronales depassent les montants maximums prevus au texte du regime.

Ces cotisations sont remises au fiduciaire au moment determine par l'employeur.


LIMITES DES COTISATIONS PATRONALES

Pour une annee donnee, les cotisations de base et complementaires pour l'ensemble des participants sont limitees a 5 % du benefice avant impot de la compagnie. Lorsque les cotisations atteignent cette limite, les cotisations a verser pour un participant seront alors egales a celles prevues, sans tenir compte de la limite, multipliees par le ratio suivant:

cotisations globales avec limite
cotisations globales sans limite

EXHIBIT 10.7


STOCK OPTION PLAN

OF EXFO ELECTRO-OPTICAL ENGINEERING INC.


1. PURPOSE OF THE PLAN

1.1 The purpose of the stock option plan (the "PLAN") for directors, executive officers, employees and other persons or companies providing ongoing management or consulting services (the "CONSULTANTS") to EXFO Electro-Optical Engineering Inc. (the "CORPORATION") or to any of the Subsidiaries of the Corporation is to secure for the Corporation and its shareholders the benefit of an incentive to partake in share ownership by directors, executive officers and employees of the Corporation and its Subsidiaries, as the case may be, and by certain Consultants who provide services on a continuous basis. For the purposes of the Plan, "SUBSIDIARIES" shall mean (i) any legal entity of which the Corporation is the holder or the beneficiary, at the time of the granting of the option, directly or indirectly, otherwise than by way of security only, of securities to which are attached over 50% of the votes enabling it to elect the majority of the directors of such entity as well as any subsidiary of such legal entity and (ii) any legal entity in which the Corporation or a subsidiary of the Corporation holds at least 50% of the voting rights or in which it has a majority interest and of which the Corporation or a subsidiary of the Corporation manages the operations.

2. ADMINISTRATION

The Plan shall be administered by the Corporation's Board of Directors (the "BOARD") or the Human Resources Committee or any other committee constituted from time to time (the "COMMITTEE"). The Board or the Committee shall have full and complete latitude to interpret the Plan and to establish the rules and regulations applying to it and to make all other determinations it deems necessary or useful for the administration of the Plan, including without limiting the scope of the foregoing and subject to subsection 6.3, to change an Early Expiry Date (as defined hereinafter) provided that such interpretations, rules, regulations and determinations shall be consistent with the relevant policy statements of the competent securities authorities and the rules of the stock exchanges on which the securities of the Corporation are listed.

3. SHARES SUBJECT TO THE PLAN

The shares subject to the Plan are the Subordinate Voting Shares (the "SHARES") of the Corporation. The total number of Shares that may be issued under the Plan shall not exceed 4,470,961 Shares of the Corporation, subject to the adjustment under Section 11, and no Optionee (as defined hereinbelow) shall hold options to purchase more than 5% of the number of Shares issued and outstanding from time to time. All of the Shares covered by options that will have expired or have been cancelled without being exercised according to


-2-

the terms of the Plan shall become reserved Shares for the purposes of options that may be subsequently granted under the terms of the Plan.

4. GRANT OF OPTIONS

The Board or the Committee shall from time to time designate the directors, officers or employees of the Corporation or any of its Subsidiaries, as the case may be, or the Consultants to whom options shall be granted (an "OPTIONEE") and the number of Shares covered by each of such option. Any Optionee may hold more than one option. The granting of each option shall be evidenced by a letter from the Corporation addressed to the Optionee setting forth the number of Shares covered by such option, the subscription price, the terms and conditions of exercise of the option and the option period.

5. SUBSCRIPTION PRICE

The subscription price of the Shares subject to an option shall be established by the Board or the Committee at the time of the grant, but such price shall not be less than the market price of the Shares at the date of the granting of the option (the "GRANT DATE"), calculated as the greater of the closing prices of the Shares on The Toronto Stock Exchange and the Nasdaq National Market on the last trading day preceding the Grant Date or, if the Shares did not trade on such last trading day, the greater of the average, rounded off to the nearest cent, of the bid and ask prices for the Shares on The Toronto Stock Exchange and the Nasdaq National Market at the close of trading on such last trading day preceding the Grant Date (the "SUBSCRIPTION PRICE").

The closing price of the Shares or, as the case may be, the average of the bid and ask prices of the Shares at the close of trading on the NASDAQ National Market shall be converted into Canadian dollars at the noon buying rate of Federal Reserve Bank of New York on the Grant Date when such conversion is required.

6. OPTION PERIOD

6.1 Subject to the provisions of subsections 6.2 and 6.3, each option shall be exercisable during a period established by the Board or the Committee (the "OPTION PERIOD"); such period shall commence no earlier than the Grant Date and shall terminate no later than ten years after such date.

6.2 Notwithstanding the provisions of subsection 6.1, an option shall not be exercisable by an Optionee from and after each and every one of the following dates (an "EARLY EXPIRY DATE"), unless the Board or the Committee decides otherwise:

6.2.1     in the case where the Optionee is an officer or an employee, the
          date on which the Optionee resigns or voluntary leaves his
          employment with the Corporation or one of its subsidiaries, as
          the case may be, or the date on which the employment of the

                                 -3-

          Optionee with the Corporation or one of its Subsidiaries is
          terminated for a good and sufficient cause, as the case may be;

6.2.2     in the case where the Optionee is a director of the Corporation
          or one of its Subsidiaries, as the case may be, but is not
          employed by either the Corporation or one of its subsidiaries,
          30 days following the date on which such Optionee ceases to be a
          member of the Board of Directors for any reason other than death;

6.2.3     (i) in the case where the Optionee is an officer or employee,
          6 months following the date on which the Optionee's employment
          with the Corporation or any of its Subsidiaries, as the case may
          be, is terminated by reason of death or (ii) in the case where
          the Optionee is a director of the Corporation or any of its
          Subsidiaries, as the case may be, but is not employed by either
          the Corporation or any of its Subsidiaries, 6 months following
          the date on which such Optionee ceases to be a member of the
          Board of Directors by reason of death;

6.2.4     in the case where the Optionee is an officer or employee, 30 days
          following the date on which the Optionee's employment with the
          Corporation or any of its Subsidiaries, as the case may be, is
          terminated for any cause or reason other than those mentioned in
          paragraphs 6.2.1 and 6.2.2, including, without limiting the scope
          of the foregoing, disability, illness, retirement or early
          retirement. Notwithstanding the foregoing, in case of retirement
          or early retirement of an officer or employee, the Board or the
          Committee may at its own discretion but subject to Section 2,
          extend the Early Expiry Date mentioned in this paragraph 6.2.4;

6.2.5     in the case where the Optionee is a Consultant, 30 days following
          the date on which his contract as a Consultant is terminated or,
          as the case may be, 30 days following the receipt by the
          Consultant of a notice from the Corporation indicating that the
          options must be exercised within 30 days from the date of receipt
          of the notice.

6.3 The rules set forth in paragraph 6.2 shall not be interpreted in such a manner as to extend the Option Period beyond 10 years.

6.4 All rights conferred by an option not exercised at the termination of the Option Period or from and after any Early Expiry Date shall be forfeited.

7. EXERCISE OF OPTIONS

7.1 Subject to the provisions of section 6, an option may be exercised in whole, at any time, or in part, from time to time, during the Option Period, but in all cases in accordance with the exercise frequency established by the Board or the Committee and applicable at the time of the grant.

The Subscription Form shall also be accompanied by a certified cheque made payable to the Corporation in the amount of the Subscription Price.

13. FINAL PROVISIONS

13.1 The Corporation's obligation to issue options granted or Shares under the terms of the Plan is subject to all of the applicable laws, regulations or rules of any governmental regulatory agency or other competent authority in respect of the issuance or distribution of securities and to the rules of any stock exchange on which the Shares of the Corporation are listed. Each Optionee shall agree to comply with such laws, regulations and rules and to provide to the Corporation any information or undertaking required to comply with such laws, regulations and rules.

13.2 The participation in the Plan of a director, an executive officer or an employee of the Corporation or any of its Subsidiaries, as well as any Consultant, shall be entirely optional and shall not be interpreted as conferring upon a director, an executive officer or an employee of the Corporation or any of its Subsidiaries, as well as any Consultant, any right or privilege whatsoever, except for the rights and privileges set out expressly in the Plan. Neither the Plan nor any act that is done under the terms of the Plan shall be interpreted as restricting the right of the Corporation or any of its Subsidiaries to terminate the employment of an executive officer or employee at any time, as well as any contractual relationship with any Consultant. Any notice of dismissal given to an executive officer or employee, as well as to any Consultant, at the time his/her employment is terminated, or any payment in the place and stead of such notice, or any combination of the two, shall not have the effect of extending the duration of the employment or the contractual relationship for purposes of the Plan.

13.3 No director, executive officer or employee of the Corporation or any of its Subsidiaries, as well as any Consultant, shall acquire the automatic right to be granted one or more options


- 7 -

under the terms of the Plan by reason of any previous grant of options under the terms of the Plan.

13.4 The Plan does not provide for any guarantee in respect of any loss or profit that may result from fluctuations in the price of the Shares.

13.5 (i)    The Corporation and its Subsidiaries shall assume no responsibility
            as regards the tax consequences that participation in the Plan will
            have for a director, an executive officer or an employee of the
            Corporation or any of its Subsidiaries, as well as any Consultant,
            and such persons are urged to consult their own tax advisors in such
            regard.

     (ii)   An Optionee may be required to pay to the Corporation or any
            subsidiary and the Corporation or any Subsidiary shall have the
            right and is hereby authorized to withhold from any Shares or other
            property deliverable under any Option or from any compensation or
            other amounts owing to an Optionee the amount (in cash or Shares) of
            any required tax withholding and payroll taxes in respect of an
            Option, its exercise, or any payment or transfer under an Option or
            under the Plan and to take such other action as may be necessary in
            the opinion of the Corporation to satisfy all obligations for the
            payment of such taxes.

     (iii)  Without limiting the generality of clause (ii) above an Optionee may
            satisfy, in whole or in part, the foregoing withholding liability
            (but no more than the minimum required withholding liability) by
            delivery of Shares owned by the Optionee with a fair market value
            equal to such withholding liability (provided that such Shares are
            not subject to any pledge or other security interest and have either
            been held by the Optionee for 6 months, previously acquired by the
            Optionee on the open market or meet such other requirements as the
            Committee may determine necessary in order to avoid an accounting
            earnings charge), or by having the Corporation withhold from the
            number of Shares otherwise issuable pursuant to the exercise or
            settlement of the Option a number of Shares with a fair market value
            equal to such withholding liability.

13.6 The Plan and any option granted under the terms of the Plan shall be governed and interpreted according to the laws of the province of Quebec and the laws of Canada applicable thereto.

13.8 The Plan is dated as of May 25, 2000.

4

"blue sky" laws all or part of their Registrable Securities, by delivering a written request therefor to the Company specifying the number of Registrable Securities to be included in such registration and the intended method of distribution thereof. All requests pursuant to this Section 3.1(a)(i) are referred to herein as "Demand Registration Requests," and the registrations requested are referred to herein as "Demand Registrations." As promptly as practicable, but no later than ten days after receipt of a Demand Registration Request, the Company shall give written notice of such Demand Registration Request to all Holders of record of Registrable Securities.

(ii) The Company, subject to Sections 3.3 and 3.6 below, shall include in a Demand Registration (A) the Registrable Securities of the Holder(s) which requested such registration and (B) the Registrable Securities of any Holder which shall have made a written request to the Company for registration thereof (which request shall specify the maximum number of Registrable Securities intended to be disposed of by such Holder) within 30 days after the receipt of written notice pursuant to clause (i) (or 15 days if, at the request of the Holder(s) which requested such registration, the Company states in such written notice or gives telephonic notice to all Holders, with written confirmation to follow promptly thereafter, that such registration will be on Form S-3, Form F-3 or Form F-10 (or equivalent registration forms then in effect)).

(iii) The Company shall, as expeditiously as possible following a Demand Registration Request, use its reasonable best efforts to (A) effect such registration under the Securities Act (including, without limitation, by means of (i) a shelf registration pursuant to Rule 415 under the Securities Act if so requested and if the Company is then eligible to use such a registration or
(ii) a registration under the Multi-jurisdictional Disclosure System ("MJDS") if so requested and if the Company is then eligible to use such registration) of the Registrable Securities which the Company has been so requested to register, for distribution in accordance with such intended method of distribution and (B) if requested by the Holder(s) which requested such registration, obtain acceleration of the effective date of the registration statement relating to such registration.

(b) The demand registration rights granted to the Holders in
Section 3.1(a) are subject to the following limitations: (i) each Demand Registration must include Registrable Securities having an aggregate market value of at least U.S.$10,000,000, which market value shall be determined by multiplying the number of Registrable Securities to be included in such Demand Registration by the Fair Market Value determined as of the date the Demand Registration Request in respect of such Demand Registration is made; provided that the limitations set forth in this clause
(i) shall not be in effect at any time the Holders' Registrable Securities may not be sold pursuant to Rule 144 under the Securities Act because of the Company's failure to comply with the information requirements thereunder, unless at such time, the


5

Company's outside counsel (which shall be reasonably acceptable to Mr. Lamonde if such Holder is a member of the Lamonde Group) delivers a written opinion of counsel to such Holder proposing to register Registrable Securities to the effect that such Holder's Registrable Securities may be publicly offered and sold without registration under the Securities Act); (ii) the Lamonde Group may only make a demand for registration pursuant to Section 3.1(a)(i) once within any twelve consecutive month period; (iii) the Company shall not be required to cause a registration pursuant to Section 3.1(a)(i) to be declared effective within a period of 180 days after the effective date of any other registration statement of the Company effected in connection with an underwritten offering by the Company;
(iv) if the Board of Directors of the Company, in its good faith judgment, determines that any registration of Registrable Securities should not be made or continued because it would materially interfere with any material financing, acquisition, corporate reorganization or amalgamation or other transaction involving the Company or any of its subsidiaries (a "Valid Business Reason"), (A) the Company may postpone filing a registration statement relating to a Demand Registration Request until such Valid Business Reason no longer exists, but any such delay cannot exceed three months, and (B) in case a registration statement has been filed relating to a Demand Registration Request, if the Valid Business Reason has not resulted from actions taken by the Company, the Company may cause such registration statement to be withdrawn and its effectiveness terminated or may postpone amending or supplementing such registration statement, and the Company shall give written notice of its determination to postpone or withdraw a registration statement and of the fact that the Valid Business Reason for such postponement or withdrawal no longer exists, in each case, promptly after the occurrence thereof; and (v) from and after such time as members of the Lamonde Group beneficially own, in the aggregate, less than 10% of the outstanding Voting Shares, the Company shall only be required to effect one Demand Registration at the request of the Lamonde Group; provided, that any Demand Registration requested by the Lamonde Group at such time shall not count as the one Demand Registration permitted by this subclause
(v) if, immediately after giving effect to such registration, and due to the allocation provisions of
Section 3.3(a) below, the Lamonde Group beneficially owns, in the aggregate, 5% or more of the outstanding Voting Shares. If the Company shall give any notice of postponement or withdrawal of any registration statement, the Company shall not, during the period of postponement or withdrawal, register any Voting Shares, other than pursuant to a registration statement on such form or similar form(s) solely for registration of securities in connection with an employee benefit plan or dividend reinvestment plan or an amalgamation or consolidation. Each Holder of Registrable Securities agrees that, upon receipt of any notice from the Company that the Company has determined to withdraw any registration statement pursuant to clause (iv) above, such Holder will discontinue its disposition of Registrable Securities pursuant to such registration statement and, if so directed by the Company, will deliver to the Company (at the Company's expense) all copies, other than permanent file copies, then in such Holder's possession of the prospectus covering such Registrable Securities that was in effect at


6
the time of receipt of such notice. If the Company shall
have withdrawn or prematurely terminated a registration
statement filed under Section 3.1(a) (whether pursuant to
clause (iv) above or as a result of any stop order,
injunction or other order or requirement of the Commission
or any other governmental agency or court), the Company
shall not be considered to have effected an effective
registration for the purposes of this Section 3.1(b) until
the Company shall have filed a new registration statement
covering the Registrable Securities covered by the withdrawn
registration statement and such registration statement shall
have been declared effective and shall not have been
withdrawn. If the Company shall give any notice of
withdrawal or postponement of a registration statement, the
Company shall, at such time as the Valid Business Reason
that caused such withdrawal or postponement no longer exists
(but in no event later than three months after the date of
the postponement), use its reasonable best efforts to effect
the registration under the Securities Act and under
applicable state securities or "blue sky" laws of the
Registrable Securities covered by the withdrawn or postponed
registration statement in accordance with this Section 3.1
(unless the Holder(s) delivering the Demand Registration
Request shall have withdrawn such request, in which case the
Company shall not be considered to have effected an
effective registration for the purposes of this Section
3.1(b)), and such registration shall not be withdrawn or
postponed pursuant to clause (iv) above.

(c) The Company, subject to Sections 3.3 and 3.6 below, may elect to include in any registration statement and offering made pursuant to Section 3.1(a), authorized but unissued Voting Shares or Voting Shares held by the Company as treasury shares; provided, that such inclusion shall be permitted only to the extent that it is pursuant to and subject to the terms of the underwriting agreement or arrangements, if any, entered into by the Holders exercising the demand registration rights granted to the Holders under
Section 3.1(a).

(d) The lead managing underwriter (the "Lead Underwriter") for any Demand Registration shall be selected by the party or parties making the demand for such registration; provided, that such underwriter shall be an investment banking firm of national reputation unaffiliated with such parties and reasonably satisfactory to the Company.

3.2. Piggyback Registration.

(a) If, at any time, the Company proposes or is required to register any of its equity securities (including pursuant to any registration statement which generally registers equity and debt securities without specifying the type of security or the amount) under the Securities Act (other than pursuant to (i) registrations on such form or similar form(s) solely for registration of securities in connection with an employee benefit plan or dividend reinvestment plan or an amalgamation or consolidation or (ii) a Demand Registration under Section 3.1) on a registration


7

statement on Form S-1, Form S-2, Form S-3, Form F-1, Form F-2 or Form F-3 (or an equivalent general registration form then in effect), whether or not for its own account, the Company shall give prompt written notice of its intention to do so to each of the Holders of record of Registrable Securities. Upon the written request of any Holder, made within 15 days following the receipt of any such written notice (which request shall specify the maximum number of Registrable Securities intended to be disposed of by such Holder and the intended method of distribution thereof), the Company shall, subject to Sections 3.2(b), 3.3 and 3.6 below, use its reasonable best efforts to cause all such Registrable Securities, the Holders of which have so requested the registration thereof, to be registered under the Securities Act and applicable state securities or "blue sky" laws (with the securities which the Company at the time proposes to register) to permit the sale or other disposition by the Holders (in accordance with the intended method of distribution thereof) of the Registrable Securities to be so registered. No registration effected under this Section 3.2(a) shall relieve the Company of its obligations to effect registrations upon request under
Section 3.1.

(b) If, at any time after giving written notice of its intention to register any equity securities and prior to the effective date of the registration statement filed in connection with such registration, the Company shall determine for any reason not to register or to delay registration of such equity securities, the Company may, at its election, give written notice of such determination to all Holders of record of Registrable Securities and (i) in the case of a determination not to register, shall be relieved of its obligation to register any Registrable Securities in connection with such abandoned registration, and (ii) in case of a determination to delay such registration of its equity securities, shall be permitted to delay the registration of such Registrable Securities for the same period as the delay in registering such other equity securities, in each case, without prejudice, however, to the rights of Holders under Section 3.1.

(c) Any Holder shall have the right to withdraw its request for inclusion of its Registrable Securities in any registration statement pursuant to this Section 3.2 by giving written notice to the Company of its request to withdraw; provided, however, that (i) such request must be made in writing prior to the earlier of the execution of the underwriting agreement or the execution of the custody agreement with respect to such registration and (ii) such withdrawal shall be irrevocable and, after making such withdrawal, a Holder shall no longer have any right to include Registrable Securities in the registration as to which such withdrawal was made.

3.3. Allocation of Securities Included in Registration Statement.

(a) If any requested registration pursuant to Section 3.1 involves an underwritten offering and the Lead Underwriter shall advise the Company that, in its view, the number of securities requested to be included in such registration (including those securities requested by the Company to be included in such


8

registration) exceeds the largest number (the "Section 3.1 Sale Number") that can be sold in an orderly manner in such offering within a price range acceptable to the Holders of Registrable Securities proposed to be registered, the Company shall include in such registration:

(i) all Registrable Securities requested to be included in such registration by Holders of Registrable Securities; provided, however, that if the number of such Registrable Securities exceeds the Section 3.1 Sale Number, the number of such Registrable Securities (not to exceed the Section
3.1 Sale Number) to be included in such registration shall be allocated on a pro rata basis among all Holders requesting that Registrable Securities be included in such registration, based on the number of Registrable Securities then owned by each Holder requesting inclusion in relation to the number of Registrable Securities owned by all Holders requesting inclusion; and

(ii) to the extent that the number of Registrable Securities to be included by all Holders is less than the Section 3.1 Sale Number, securities that the Company proposes to register.

If, as a result of the proration provisions of this
Section 3.3(a), any Holder shall not be entitled to include all Registrable Securities in a registration that such Holder has requested to be included, such Holder may elect to withdraw his request to include Registrable Securities in such registration or may reduce the number requested to be included; provided, however, that (x) such request must be made in writing prior to the earlier of the execution of the underwriting agreement or the execution of the custody agreement with respect to such registration and (y) such withdrawal shall be irrevocable and, after making such withdrawal, a Holder shall no longer have any right to include Registrable Securities in the registration as to which such withdrawal was made.

(b) If any registration pursuant to Section 3.2 involves an underwritten offering and the Lead Underwriter shall advise the Company that, in its view, the number of securities requested to be included in such registration exceeds the number (the "Section 3.2 Sale Number") that can be sold in an orderly manner in such registration within a price range acceptable to the Company, the Company shall include in such registration:

(i) all Voting Shares or securities convertible into, or exchangeable or exercisable for, Voting Shares that the Company proposes to register for its own account (the "Company Securities"); and

(ii) to the extent that the number of Company Securities is less than the Section 3.2 Sale Number, all Registrable Securities requested


9

to be included by all Holders; provided, however, that, if the number of such Registrable Securities exceeds the Section 3.2 Sale Number less the number of Company Securities, then the number of such Registrable Securities included in such registration shall be allocated on a pro rata basis based on the number of Registrable Securities owned by each Holder requesting inclusion in relation to the number of Registrable Securities owned by all Holders requesting inclusion.

3.4. Registration Procedures. If and whenever the Company is required by the provisions of this Agreement to use its reasonable best efforts to effect or cause the registration of any Registrable Securities under the Securities Act and applicable state securities or "blue sky" laws as provided in this Agreement, the Company shall, as expeditiously as possible:

(a) prepare and file with the Commission a registration statement on an appropriate registration form of the Commission for the disposition of such Registrable Securities in accordance with the intended method of disposition thereof, which form (i) shall be selected by the Company; provided, however, that the Company shall clear a prospectus under any Canadian Securities Laws and elect to use an MJDS form if so requested and if the Company is eligible to use such form and (ii) shall, in the case of a shelf registration, be available for the sale of the Registrable Securities by the selling Holders thereof and such registration statement shall comply as to form in all material respects with the requirements of the applicable form and include all financial statements required by the Commission to be filed therewith, and the Company shall use its reasonable best efforts to cause such registration statement to become and remain effective (provided, however, that before filing a registration statement or prospectus or any amendments or supplements thereto, or comparable statements under state securities or "blue sky" laws, the Company will furnish to the counsel of any Holder participating in the planned offering and the underwriters, if any, copies of all such documents proposed to be filed (including all exhibits thereto), which documents will be subject to the reasonable review and reasonable comment of such counsel, and the Company shall not file any registration statement or amendment thereto or any prospectus or supplement thereto to which the holders of a majority of the Registrable Securities covered by such registration statement or the underwriters, if any, shall reasonably object in writing);

(b) prepare and file with the Commission such amendments and supplements to such registration statement and the prospectus used in connection therewith as may be necessary to keep such registration statement effective until the earlier of (i) such time as all of such Registrable Securities and other securities have been disposed of in accordance with the intended methods of disposition by the sellers thereof as set forth in such registration statement and (ii) such period (which shall not be required to exceed 150 days in the case of a registration pursuant to Section 3.1 or 120 days in the case of a registration pursuant to
Section 3.2, unless reasonably


10

(d) use its reasonable best efforts to register or qualify the Registrable Securities covered by such registration statement under such state securities or "blue sky" laws as any sellers of Registrable Securities or the Lead Underwriter, if any, shall reasonably request, and do any and all other acts and things which may be reasonably necessary or advisable to enable such sellers or underwriter, if any, to consummate the disposition of the Registrable Securities in any such jurisdiction, except that in no event shall the Company be required to qualify to do business as a foreign corporation in any jurisdiction where it would not, but for the requirements of this paragraph
(d), be required to be so qualified, to subject itself to taxation in any such jurisdiction or to consent to general service of process in any such jurisdiction;

(e) notify each Holder selling Registrable Securities covered by such registration statement and the Lead Underwriter, if any: (i) when the registration statement, any pre-effective amendment, the prospectus or any prospectus supplement related thereto or post-effective amendment to the registration statement has been filed and, with respect to the registration statement or any post-effective amendment, when the same has become effective; (ii) of any request by the Commission or any state securities authority for amendments or supplements to the registration statement or the prospectus related thereto or for additional information; (iii) of the issuance by the Commission of any stop order suspending the effectiveness of the registration statement or the initiation of any proceedings for that purpose; (iv) of


11

the receipt by the Company of any notification with respect to the suspension of the qualification of any Registrable Securities for sale under applicable state securities or "blue sky" laws or the initiation of any proceeding for such purpose; (v) of the existence of any fact of which the Company becomes aware which results in the registration statement, the prospectus related thereto or any document incorporated therein by reference containing an untrue statement of a material fact or omitting to state a material fact required to be stated therein or necessary to make any statement therein not misleading; and (vi) if at any time the representations and warranties contemplated by Section 4 below cease to be true and correct in all material respects and, if the notification relates to an event described in clause (v), the Company shall promptly prepare and furnish to each such seller and each underwriter, if any, a reasonable number of copies of a prospectus supplemented or amended so that, as thereafter delivered to the purchasers of such Registrable Securities, such prospectus shall not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein in the light of the circumstances under which they were made not misleading;

The Holders of the Registrable Securities which are to be distributed by such underwriters shall be parties to such underwriting agreement and may, at their option, require that the Company make to and for the benefit of such Holders the representations, warranties and covenants of the Company which are being made to and for the benefit of such underwriters and which are of the type customarily provided to institutional investors in secondary offerings;

(j) obtain an opinion from the Company's counsel and a "cold comfort" letter from the Company's regular independent chartered accountants in customary form and covering such matters as are customarily covered by such opinions and "cold comfort" letters delivered to underwriters in underwritten public offerings, which opinion and letter shall be reasonably satisfactory to the underwriters, if any, and the designated member of the Lamonde Group (initially Mr. Lamonde or his designee) and furnish to each Holder participating in the offering and to each underwriter, if any, a copy of such opinion and letter addressed to such Holder or underwriter;

(o) prior to the filing of any document which is to be incorporated by reference into the registration statement or the prospectus (after the initial filing of such registration statement), provide copies of such document to counsel to the selling holders of Registrable Securities and to the underwriters, if any, and make the Company's representatives reasonably available for discussion of such document and make such changes in such document prior to the filing thereof as counsel for such selling holders or underwriters may reasonably request;

(q) cooperate with the selling holders of Registrable Securities and the Lead Underwriter, if any, to facilitate the timely preparation and delivery of certificates not bearing any restrictive legends representing the Registrable Securities to be sold, and cause such Registrable Securities to be issued in such denominations and registered in such names in accordance with the underwriting agreement prior to any sale of Registrable Securities to the underwriters or, if not an underwritten offering, in accordance with the instructions of the selling holders of Registrable Securities at least three business days prior to any sale of Registrable Securities; and

(r) take all such other commercially reasonable actions as are necessary or advisable in order to expedite or facilitate the disposition of such Registrable Securities.

The Company may require as a condition precedent to the Company's obligations under this Section 3.4 that each seller of Registrable Securities as to which any registration is being effected furnish the Company such information regarding such seller and the distribution of such securities as the Company may from time to time reasonably request; provided, that such information shall be used only in connection with such registration.

Each Holder of Registrable Securities agrees that, upon receipt of any notice from the Company of the happening of any event of the kind described in clause (v) of paragraph (e) of this Section 3.4, such Holder will discontinue such Holder's disposition of Registrable Securities pursuant to the registration statement


14

covering such Registrable Securities until such Holder's receipt of the copies of the supplemented or amended prospectus contemplated by paragraph (e) of this
Section 3.4 and, if so directed by the Company, will deliver to the Company (at the Company's expense) all copies, other than permanent file copies, then in such Holder's possession of the prospectus covering such Registrable Securities that was in effect at the time of receipt of such notice. In the event the Company shall give any such notice, the applicable period mentioned in paragraph
(b) of this Section 3.4 shall be extended by the number of days during such period from and including the date of the giving of such notice to and including the date when each seller of any Registrable Securities covered by such registration statement shall have received the copies of the supplemented or amended prospectus contemplated by paragraph (e) of this Section 3.4.

If any such registration statement or comparable statement under "blue sky" laws refers to any Holder by name or otherwise as the Holder of any securities of the Company, then such Holder shall have the right to require (i) the insertion therein of language, in form and substance satisfactory to such Holder and the Company, to the effect that the holding by such Holder of such securities is not to be construed as a recommendation by such Holder of the investment quality of the Company's securities covered thereby and that such holding does not imply that such Holder will assist in meeting any future financial requirements of the Company or (ii) in the event that such reference to such Holder by name or otherwise is not in the judgment of the Company, as advised by counsel, required by the Securities Act or any similar federal statute or any applicable state securities or "blue sky" laws then in force, the deletion of the reference to such Holder.

3.5. Registration Expenses. The Company shall, whether or not any registration pursuant to this Agreement becomes effective, pay all expenses incident to the Company's performance of or compliance with this Article 3, including (i) Commission, stock exchange or NASD registration and filing fees and all listing fees, (ii) fees and expenses of compliance with applicable state securities or "blue sky" laws and in connection with the preparation of a "blue sky" survey, including without limitation, reasonable fees and expenses of "blue sky" counsel, (iii) printing and engraving expenses, (iv) messenger and delivery expenses, (v) internal expenses (including, without limitation, all salaries and expenses of the Company's officers and employees performing legal and accounting duties), (vi) fees and disbursements of counsel for the Company, (vii) with respect to each registration, the fees and disbursements of one Canadian counsel and one U.S. counsel for the selling Holders (selected by the Holders making the Demand Registration Request, in the case of a registration pursuant to Section 3.1, and selected by the Holders of a majority of the Registrable Securities included in such registration, in the case of a registration pursuant to
Section 3.2, (viii) fees and disbursements of all independent chartered accountants (including the expenses of any audit and/or "cold comfort" letter) and fees and expenses of other persons, including special experts, retained by the Company and

(ix) any other fees and disbursements of underwriters, if any, customarily paid by issuers or sellers of securities. Notwithstanding the foregoing, (i) the provisions of this Section 3.5 shall be deemed amended to the extent necessary to cause these expense provisions to comply with applicable laws and regulations and stock exchange rules and (ii) in connection with any registration hereunder, each Holder of Registrable Securities being registered shall pay all underwriting discounts and commissions and any capital gains, income or transfer taxes, if any, attributable to such Holder's Registrable Securities.

3.6. Certain Limitations on Registration Rights. In the case of any registration under Section 3.1 pursuant to an underwritten offering, or in the case of a registration under Section 3.2 if the Company has determined to enter into an underwriting agreement in connection therewith, all Registrable Securities to be included in such registration shall be subject to an underwriting agreement and no person may participate in such registration unless such person agrees to sell such person's securities on the basis provided therein and completes and/or executes all questionnaires, indemnities, lock-ups, underwriting agreements and other documents (other than powers of attorney), in each case in customary form and substance, which must be executed in connection therewith.

3.7. Limitations on Sale or Distribution of Other Securities.

(a) If requested in writing by the Company or the Lead Underwriter, if any, of any registration effected pursuant to Section 3.1 or 3.2, each Holder of Registrable Securities agrees not to effect any public sale or distribution, including any sale pursuant to Rule 144 under the Securities Act, of any Registrable Securities, or of any other equity security of the Company or of any security convertible into or exchangeable or exercisable for any equity security of the Company (other than as part of such underwritten public offering) during the time period reasonably requested by the Lead Underwriter, not to exceed 180 days, and the Company hereby also so agrees (except that the Company may effect any sale or distribution of any such securities pursuant to a registration on such form or similar form(s) solely for registration in connection with an employee benefit plan or dividend reinvestment plan or a merger, amalgamation or consolidation) and agrees to use its reasonable efforts to cause each holder of any equity security or of any security convertible into or exchangeable or exercisable for any equity security of the Company purchased from the Company at any time other than in a public offering so to agree.

(b) The Company hereby agrees that if it shall previously have received a request for registration pursuant to Section 3.1 or 3.2, and if such previous registration shall not have been withdrawn or abandoned, the Company shall not, without the prior written consent of the Lead Underwriter of such previous registration, effect any registration of any of its securities under the Securities Act


16

(other than a registration on such form or similar form(s)
solely for registration in connection with an employee benefit plan or dividend reinvestment plan or a merger, amalgamation or consolidation) or under any applicable state securities or "blue sky" laws, whether or not for sale for its own account, until a period 180 days shall have elapsed from the effective date of such previous registration and the Company shall so provide in any registration rights agreements hereafter entered into with respect to any of its securities.

3.8. No Required Sale. Nothing in this Agreement shall be deemed to create an independent obligation on the part of any Holder to sell any Registrable Securities pursuant to any effective registration statement.

3.9. Indemnification.

(a) In the event of any registration of any securities of the Company under the Securities Act pursuant to this Article 3, the Company will, and hereby does, indemnify and hold harmless, to the fullest extent permitted by law, the seller of any Registrable Securities covered by such registration statement, its directors, officers, fiduciaries, employees, trustees and shareholders or general and limited partners (and the directors, officers, employees and shareholders thereof), each other Person who participates as an underwriter in the offering or sale of such securities, each officer, director, employee, shareholder or partner of such underwriter and each other Person, if any, who controls such seller or any such underwriter within the meaning of the Securities Act, against any and all losses, claims, damages or liabilities, joint or several, actions or proceedings (whether commenced or threatened) in respect thereof ("Claims") and expenses (including reasonable fees of counsel and any amounts paid in any settlement effected with the Company's consent, which consent shall not be unreasonably withheld or delayed) to which each such indemnified party may become subject under the Securities Act or otherwise, insofar as such Claims or expenses arise out of or are based upon (i) any untrue statement or alleged untrue statement of a material fact contained in any registration statement under which such securities were registered under the Securities Act or the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, (ii) any untrue statement or alleged untrue statement of a material fact contained in any preliminary, final or summary prospectus or any amendment or supplement thereto, together with the documents incorporated by reference therein, or the omission or alleged omission to state therein a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, or (iii) any violation by the Company of any U.S. federal, state or common law rule or regulation applicable to the Company and relating to action required of or inaction by the Company in connection with any such registration, and the Company will reimburse any such indemnified party for any legal or other expenses reasonably incurred by such indemnified party in


17

connection with investigating or defending any such Claim as such expenses are incurred; provided, that the Company shall not be liable to any such indemnified party in any such case to the extent such Claim or expense arises out of or is based upon any untrue statement or alleged untrue statement of a material fact or omission or alleged omission of a material fact made in such registration statement or amendment thereof or supplement thereto or in any such prospectus or any preliminary, final or summary prospectus in reliance upon and in conformity with written information furnished to the Company by or on behalf of such indemnified party specifically for use therein. Such indemnity and reimbursement of expenses shall remain in full force and effect regardless of any investigation made by or on behalf of such indemnified party and shall survive the transfer of such securities by such seller.

(b) Each Holder of Registrable Securities that are included in the securities as to which any registration under Section 3.1 or 3.2 is being effected (and, if the Company requires as a condition to including any Registrable Securities in any registration statement filed in accordance with Section 3.1 or 3.2, any underwriter) shall, severally and not jointly, indemnify and hold harmless (in the same manner and to the same extent as set forth in paragraph (a) of this
Section 3.9) to the extent permitted by law the Company, its officers and directors, each Person controlling the Company within the meaning of the Securities Act and all other prospective sellers and their directors, officers, general and limited partners and respective controlling Persons with respect to any untrue statement or alleged untrue statement of any material fact in, or omission or alleged omission of any material fact from, such registration statement, any preliminary, final or summary prospectus contained therein, or any amendment or supplement thereto, if such statement or alleged statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Company or its representatives by or on behalf of such Holder or underwriter specifically stating that it is for use in such registration statement, preliminary, final or summary prospectus or amendment or supplement thereto or document incorporated by reference into any of the foregoing; provided, however, that the aggregate amount which any such Holder shall be required to pay pursuant to this Section 3.9(b) and Sections 3.9(c) and
(e) shall be limited to the amount of the net proceeds received by such person upon the sale of the Registrable Securities pursuant to the registration statement giving rise to such claim. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of such indemnified party and shall survive the transfer of such securities by such Holder.

(c) Indemnification similar to that specified in the preceding paragraphs (a) and (b) of this Section 3.9 (with appropriate modifications) shall be given by the Company and each seller of Registrable Securities with respect to any required registration or other qualification of securities under any applicable state securities and "blue sky" laws or any filings made under any applicable Canadian Securities Laws.


18

(d) Any person entitled to indemnification under this Agreement shall notify promptly the indemnifying party in writing of the commencement of any action or proceeding with respect to which a claim for indemnification may be made pursuant to this Section 3.9, but the failure of any indemnified party to provide such notice shall not relieve the indemnifying party of its obligations under the preceding paragraphs of this Section 3.9, except to the extent the indemnifying party is materially prejudiced thereby and shall not relieve the indemnifying party from any liability which it may have to any indemnified party otherwise than under this Article
3. In case any action or proceeding is brought against an indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, unless in the reasonable opinion of outside counsel to the indemnified party a conflict of interest between such indemnified and indemnifying parties may exist in respect of such claim, to assume the defense thereof jointly with any other indemnifying party similarly notified, to the extent that it chooses, with counsel reasonably satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and after notice from the indemnifying party to such indemnified party that it so chooses, the indemnifying party shall not be liable to such indemnified party for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided, however, that
(i) if the indemnifying party fails to take reasonable steps necessary to defend diligently the action or proceeding within 20 days after receiving notice from such indemnified party that the indemnified party believes it has failed to do so, (ii) if such indemnified party who is a defendant in any action or proceeding which is also brought against the indemnifying party reasonably shall have concluded that there may be one or more legal defenses available to such indemnified party which are not available to the indemnifying party, or (iii) if representation of both parties by the same counsel is otherwise inappropriate under applicable standards of professional conduct, then, in any such case, the indemnified party shall have the right to assume or continue its own defense as set forth above (but with no more than one firm of counsel for all indemnified parties in each jurisdiction, except to the extent any indemnified party or parties reasonably shall have concluded that there may be legal defenses available to such party or parties which are not available to the other indemnified parties or to the extent representation of all indemnified parties by the same counsel is otherwise inappropriate under applicable standards of professional conduct) and the indemnifying party shall be liable for any expenses therefor. No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (A) includes an unconditional release of the indemnified party from all liability arising out


19

of such action or claim and (B) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party.

(e) If for any reason the foregoing indemnity is unavailable or is insufficient to hold harmless an indemnified party under Sections 3.9(a), (b) or (c), then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of any Claim in such proportion as is appropriate to reflect the relative benefits received by the indemnifying party on the one hand and the indemnified party on the other from such offering of securities. If, however, the allocation provided in the immediately preceding sentence is not permitted by applicable law, or if the indemnified party failed to give the notice required by subsection (d) above and the indemnifying party is materially prejudiced thereby, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the indemnifying party, on the one hand, and the indemnified party, on the other hand, as well as any other relevant equitable considerations. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the indemnifying party or the indemnified party and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The parties hereto agree that it would not be just and equitable if contributions pursuant to this Section 3.9(e) were to be determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in the preceding sentences of this Section 3.9(e). The amount paid or payable in respect of any Claim shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such Claim. No person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. Notwithstanding anything in this Section 3.9(e) to the contrary, no indemnifying party (other than the Company) shall be required pursuant to this Section 3.9(e) to contribute any amount in excess of the net proceeds received by such indemnifying party from the sale of Registrable Securities in the offering to which the losses, claims, damages or liabilities of the indemnified parties relate, less the amount of any indemnification payment made pursuant to Sections 3.9(b) and (c).

(f) The indemnity agreements contained herein shall be in addition to any other rights to indemnification or contribution which any indemnified party may have pursuant to law or contract and shall remain operative and in full force and effect regardless of any investigation made or omitted by or on behalf of any indemnified party and shall survive the transfer of the Registrable Securities by any such party.


20

(g) The indemnification and contribution required by this
Section 3.9 shall be made by periodic payments of the amount thereof during the course of the investigation or defense, as and when bills are received or expense, loss, damage or liability is incurred.

4. Underwritten Offering.

4.1. Requested Underwritten Offering. If requested by the underwriters for any underwritten offering by the Holders pursuant to a registration requested under Section 3.1, the Company shall enter into a customary underwriting agreement with the underwriters. Such underwriting agreement shall be satisfactory in form and substance to the Holders which requested such registration and shall contain such representations and warranties by, and such other agreements on the part of, the Company and such other terms as are generally prevailing in agreements of that type, including, without limitation, indemnities and contribution agreements. Any Holder participating in the offering shall be a party to such underwriting agreement and may, at its option, require that any or all of the representations and warranties by, and the other agreements on the part of, the Company to and for the benefit of such underwriters shall also be made to and for the benefit of such Holder and that any or all of the conditions precedent to the obligations of such underwriters under such underwriting agreement be conditions precedent to the obligations of such Holder. Such underwriting agreement shall also contain such representations, warranties and indemnities by the participating Holders as are customary in agreements of that type.

4.2. Piggyback Underwritten Offering. In the case of a registration pursuant to Section 3.2 hereof, if the Company shall have determined to enter into any underwriting agreements in connection therewith, all of the Holders' Registrable Securities to be included in such registration shall be subject to such underwriting agreements. Any Holder participating in such registration may, at its option, require that any or all of the representations and warranties by, and the other agreements on the part of, the Company to and for the benefit of such underwriters shall also be made to and for the benefit of such Holder and that any or all of the conditions precedent to the obligations of such underwriters under such underwriting agreement be conditions precedent to the obligations of such Holder. Such underwriting agreement shall also contain such representations, warranties and indemnities by the participating Holders as are customary in agreements of that type.

5. General.

5.1. Adjustments Affecting Registrable Securities. The Company agrees that it shall not effect or permit to occur any combination or subdivision of


21

shares which would adversely affect the ability of the Holder of any Registrable Securities to include such Registrable Securities in any registration contemplated by this Agreement or the marketability of such Registrable Securities in any such registration. The Company agrees that it will take all reasonable steps necessary to effect a subdivision of shares if in the reasonable judgment of (a) the Holder of Registrable Securities that makes a Demand Registration Request and (b) the Lead Underwriter, such subdivision would enhance the marketability of the Registrable Securities.

5.2. Rule 144. The Company covenants that it will timely file the reports required to be filed by it under the Securities Act or the Exchange Act (including, but not limited to, the reports under Sections 13 and 15(d) of the Exchange Act referred to in subparagraph (c)(1) of Rule 144 under the Securities Act), and will take such further action as any Holder of Registrable Securities may reasonably request, all to the extent required from time to time to enable such Holder to sell Registrable Securities without registration under the Securities Act within the limitation of the exemptions provided by (i) Rule 144 under the Securities Act, as such Rule may be amended from time to time, or (ii) any similar rule or regulation hereafter adopted by the Commission. Upon the request of any Holder of Registrable Securities, the Company will deliver to such Holder a written statement as to whether it has complied with such requirements.

5.3. Preparation; Reasonable Investigation. In connection with the preparation and filing of each registration statement under the Securities Act pursuant to this Agreement, the Company will give the Holders participating in the offering, their underwriters, if any, and their respective counsel, accountants and other representatives and agents the opportunity to participate in the preparation of such registration statement, each prospectus included therein or filed with the Commission, and, to the extent practicable, each amendment thereof or supplement thereto, and give each of them reasonable access to its books and records and properties and such opportunities to discuss the business of the Company and such other matters with the Company's directors, officers and employees and the independent chartered accountants who have certified its financial statements, and the Company will supply, or cause its directors, officers, employees and independent chartered accountants to supply, all other information reasonably requested by each of them, as shall be reasonably necessary or appropriate, in the opinion of the Holders' and such underwriters' respective counsel, to conduct a reasonable investigation within the meaning of the Securities Act.

5.4. Nominees for Beneficial Owners. If Registrable Securities are held by a nominee for the beneficial owner thereof, the beneficial owner thereof may, at its option, be treated as the Holder of such Registrable Securities for purposes of any request or other action by any Holder or Holders of Registrable Securities pursuant to this Agreement (or any determination of any number or percentage of shares constituting Registrable Securities held by any Holder or Holders of Registrable


22

Securities contemplated by this Agreement); provided, that the Company shall have received assurances reasonably satisfactory to it of such beneficial ownership.

5.6. Amendments and Waivers. This Agreement may be amended, modified, supplemented or waived only upon the written agreement of the party against whom enforcement of such amendment, modification, supplement or waiver is sought; provided, that the written agreement of the holders of a majority of the Registrable Securities held by the Lamonde Group shall be considered to be signed by all members of the Lamonde Group.

5.6. Notices. Except as otherwise provided in this Agreement, notices and other communications under this Agreement shall be in writing and delivered personally, by telecopy (with confirmation sent within three business days by overnight courier) or by overnight courier, addressed to the Company at 465 Godin Avenue, Vanier, Quebec G1M 3G7, Canada (telecopier: (418) 683-2170) (Attention:

Box 242, Montreal, Quebec H4Z 1E9, Canada (telecopier:
(514) 397-7600) (Attention: Robert Pare, Esq.) and to Paul, Weiss, Rifkind, Wharton & Garrison at 1285 Avenue of the Americas, New York, NY 10019, U.S.A. (telecopier: (212) 757-3990) (Attention: Edwin S. Maynard, Esq.). Each Holder, by written notice given to the Company in accordance with this Section 5.6, may change the address to which such notice or other communications are to be sent to such Holder. All such notices and communications shall be deemed to have been received on the date of delivery thereof, if delivered by hand, the next day after the sending thereof, if by overnight courier and when receipt is acknowledged, if telecopied.

5.7. Miscellaneous.

(a) This Agreement shall be binding upon and inure to the benefit of and be enforceable by the parties hereto and the respective successors and assigns of the parties hereto, whether so expressed or not. No Person other than a Holder shall be entitled to any benefits under this Agreement, except as otherwise expressly provided herein. This Agreement and the rights of the parties hereunder may be assigned by any of the parties hereto to any transferee of Registrable Securities who is a Multiple Voting Share Permitted Transferee.

(b) This Agreement (with the documents referred to herein or delivered pursuant hereto) embodies the entire agreement and understanding between the parties hereto and supersedes all prior agreements and understandings relating to the subject matter hereof.


23

(c) This Agreement shall be construed and enforced in accordance with and governed by the laws of the State of New York without giving effect to the conflicts of law principles thereof.

(d) The headings in this Agreement are for convenience of reference only and shall not limit or otherwise affect the meaning hereof. All section references are to this Agreement unless otherwise expressly provided.

(e) This Agreement may be executed in any number of counterparts, each of which shall be an original, but all of which together shall constitute one instrument.

(f) Any term or provision of this Agreement which is invalid or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity or unenforceability without rendering invalid or unenforceable the remaining terms and provisions of this Agreement or affecting the validity or enforceability of any of the terms or provisions of this Agreement in any other jurisdiction.

(g) It is hereby agreed and acknowledged that it will be impossible to measure in money the damages that would be suffered if the parties fail to comply with any of the obligations herein imposed on them and that in the event of any such failure, an aggrieved person will be irreparably damaged and will not have an adequate remedy at law. Any such person shall, therefore, be entitled to injunctive relief, including specific performance, to enforce such obligations, without the posting of any bond and if any action should be brought in equity to enforce any of the provisions of this Agreement, none of the parties hereto shall raise the defense that there is an adequate remedy at law.

(h) Each party hereto shall do and perform or cause to be done and performed all such further acts and things and shall execute and deliver all such other agreements, certificates, instruments, and documents as any other party hereto reasonably may request in order to carry out the intent and accomplish the purposes of this Agreement and the consummation of the transactions contemplated hereby.

5.8. No Inconsistent Agreements. Without the prior written consent of the Lamonde Group, initially through Mr. Lamonde or his designee, neither the Company nor any Holder will, on or after the date of this Agreement, enter into any agreement with respect to its securities which is inconsistent with the rights granted in this Agreement or otherwise conflicts with the provisions hereof, other than any lock-up agreement with the underwriters in connection with any registered offering effected hereunder, pursuant to which the Company shall agree not to register for sale, and the


24

Company shall agree not to sell or otherwise dispose of, Voting Shares or any securities convertible into or exercisable or exchangeable for Voting Shares, for a specified period following the registered offering. The Company shall not grant any other Person registration rights without the written consent of the Holders holding at least a majority of the Registrable Securities held by all of the Holders. If the Company shall at any time hereafter provide to any holder of any securities of the Company rights with respect to the registration of such securities and such rights are provided on terms or conditions more favorable to such holder than the terms or conditions applicable to the Holders herein, the Company shall provide (by way of amendment to this Agreement or otherwise) such more favorable terms or conditions to the Holders under this Agreement.

IN WITNESS WHEREOF, the undersigned have executed this Agreement as of the date set forth above.

EXHIBIT 10.15

Form of Employment Agreement of Germain Lamonde.

This Employment Agreement (the "Agreement"), dated as of May 29, 2000, is entered into by and between EXFO Electro-Optical Engineering Inc., a corporation having its principal place of business at 465 Godin Avenue, Vanier, Quebec, G1M 3G7, Canada (the "Corporation") and Germain Lamonde, an individual with an address at 4310, Cure-Drolet, Cap Rouge (Qu#bec) G1Y 3H2 (the "Employee").

TERMS OF AGREEMENT

In consideration of this Agreement and the continued employment of the Employee by the Corporation, the parties agree as follows :

1. EMPLOYMENT

The Corporation hereby agrees to continue to employ Employee, on a full-time basis to continue to act as President and Chief Executive Officer of the Corporation and to perform such acts and duties and furnish such services to the Corporation in connection with and related to that position as is customary for persons with similar positions in like companies, as the Corporation's Board of Directors shall from time to time reasonably direct. Employee hereby accepts said employment. Employee shall use his best and most diligent efforts to promote the interests of the Corporation; shall discharge his duties in a highly competent manner; and shall devote his full business time and his best business judgement, skill and knowledge to the performance of his duties and responsibilities hereunder. This Agreement shall not be interpreted to prohibit Employee from making passive personal investments or conducting private business affairs if such activities do not materially interfere with the services required under this Agreement. Employee shall report to the Board of Directors of the Corporation.

2. COMPENSATION AND BENEFITS

2.1 SALARY

During the term of this Agreement, the Corporation shall pay Employee the remuneration indicated in Schedule A. The Employee's remuneration may be adjusted in accordance with the Corporation's policies and procedures.

2.2 DISCRETIONARY BONUS

During the term of this Agreement, the Employee may participate in such bonus plan or plans of the Corporation as the Board of Directors or its Human Resources Committee may approve for the Employee. Nothing contained in this

- 1 -

Section 2.2 shall be construed to require the Board of Directors to approve a bonus plan or in any way grant to Employee the right to receive bonuses not otherwise approved.

2.3 BENEFITS

During the term of this Agreement, the Employee shall receive such benefits as customarily provided to other officers and employees of the Corporation, as applicable. Details of such benefits as of the date hereof are set forth in Schedule B of this Agreement.

2.4 VACATION

Employee may take the number of weeks of paid vacation during each year that is indicated in Schedule A at such times as shall be consistent with the Corporation's vacation policies and (in the Corporation's judgement) with the Corporation's vacation schedule for officers and other employees.

2.5 EXPENSES

Pursuant to the Corporation's customary policies in force at the time of payment, Employee shall be promptly reimbursed, against presentation of vouchers or receipts therefor, for all authorised expenses properly incurred by him on the Corporation's behalf in the performance of his duties hereunder.

3. TERMINATION

3.1 DISABILITY

If during the term of this Agreement, Employee becomes ill, disabled or otherwise incapacitated so as to be unable to perform his usual duties (a) for a period in excess of one hundred twenty (180) consecutive days and this incapacity has not been remedied within one
(1) year of the first day of disability, or (b) for more than two hundred and seventy (270) days in any consecutive eighteen (18) month period and this incapacity has not been remedied within eighteen (18) months of the first day of disability, then the Corporation shall have the right to terminate this Agreement, subject only to applicable laws, on thirty (30) day's notice to Employee. Termination pursuant to this Section 3.1 shall not affect any rights Employee may otherwise have under any disability insurance policies in effect at the time of such termination.

3.2 DISCHARGE FOR CAUSE

The Corporation may discharge Employee and terminate his employment under this Agreement for cause without further liability to the Corporation by the

- 2 -

positive vote of 2/3 of the members of the Board of Directors of the Corporation except that the Employee, if a Director, shall not be entitled to vote thereon. As used in this Section 3.2, "cause" shall mean any or all of the following;

(a) gross or wilful misconduct of Employee during the course of his employment;

(b) conviction of any criminal offence involving dishonesty, breach of trust or moral turpitude during the term of this Agreement; or

(c) Employee's breach of any of the material terms of this Agreement.

3.3 TERMINATION WITHOUT CAUSE

Upon thirty (30) days prior written notice, the Corporation may terminate this Agreement without cause by a positive vote of 2/3 of the members of the Board of Directors of the Corporation except that the Employee, if a Director, shall not be entitled to vote thereon. The Corporation shall incur no liability in this regard except that it shall continue to pay Employee the remuneration in accordance with the terms of Schedule A at his then current rate for a twenty-four (24) month period after termination if termination shall occur prior to the events mentioned in Section 3.4. In addition, any outstanding stock options that have not vested in accordance with their terms, will become fully vested and shall be exercised by Employee within a period of twelve (12) months from the time of such termination or shall be automatically terminated immediately following such twelve (12) month period.

3.4 TERMINATION FOLLOWING MERGER OR ACQUISITION

If the Corporation merges or consolidates with another corporation, if substantially all of the assets of the Corporation are sold, or if a majority of the outstanding stock of the Corporation is acquired by another person and Employee's employment is subsequently terminated by the Corporation or surviving entity other than for cause as described in 3.2, Employee shall be entitled to 24 months' remuneration plus health benefits.

In addition to the foregoing, any outstanding stock options (including substituted stock options of the acquiring or surviving corporation in such merger or acquisition) which have not vested in accordance with their terms will become fully vested and shall be exercised by Employee within a period of twelve (12) months from the time of such termination or shall be automatically terminated immediately following such twelve (12) month period. For purposes of this Section 3.4, Employee shall be entitled to treat a material demotion in title or function or a physical relocation of worksite of more than 50 km as termination under this Section 3.4, but only if Employee expressly so notifies the Corporation and terminates his employment hereunder within thirty (30)

- 3 -

days of such demotion or relocation. If Employee is offered a substantially similar position with the surviving entity and no physical relocation (beyond a 50 km radius form Employee's regular worksite) is required by such position, Employee's refusal to accept such position shall not be treated as subject to this Section 3.4, but rather shall be treated as a voluntary termination by Employee under
Section 3.5.

3.5 VOLUNTARY TERMINATION BY EMPLOYEE

In the event of voluntary termination by Employee, Employee shall be entitled only to those amounts that have accrued to the date of termination in accordance with the terms hereof or are expressly payable under the terms of the Corporation applicable benefit plans or are required by applicable law. In addition, any outstanding stock options that have not vested in accordance with their terms, will become fully vested and shall be exercised by Employee within a period of twelve (12) months from the time of such termination or shall be automatically terminated immediately following such twelve (12) month period. The Corporation may, in its sole and absolute discretion, confer such other benefits or payments as it determines, but Employee shall have no entitlement thereto.

4. MISCELLANEOUS

4.1 INSURANCE

The Corporation hereby represents that it is presently the holder of directors and officers insurance in an amount and having a coverage that is recommended by its legal advisors and insurance broker as adequate taking into account the status of the Corporation, its size and the nature of its activities.

4.5 AMENDMENT WAIVER

This Agreement may not be amended, supplemented, cancelled or discharged, except by written instrument executed by the party affected thereby. No failure to exercise, and no delay in exercising, any right, power or privilege hereunder shall operate as a waiver thereof. No waiver of any breach of any provision of this Agreement shall be deemed to be a waiver of any preceding or succeeding breach of the same or any other provision.

4.6 BINDING EFFECT, ASSIGNMENT

The Corporation will require any successor (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially all of the business and/or assets of the Corporation to assume expressly and agree to perform this Agreement in the same manner and to the same extent that the Corporation would be required to perform it as if no such event had taken place.
