PROSPECTUS


                              PRI AUTOMATION, INC.

                       2,490,516 SHARES OF COMMON STOCK

                              --------------------

     This is an offering of shares of Common Stock of PRI Automation, Inc. We 
are offering up to 2,490,516 shares of Common Stock to the holders of 
Exchangeable Shares of Promis Systems Corporation Ltd., a Canadian 
corporation, and to the holder of a warrant to purchase shares of Common 
Stock. Promis will issue the Exchangeable Shares in exchange for outstanding 
Promis Common Shares in connection with the proposed combination of PRI and 
Promis. Holders of Exchangeable Shares may then exchange one Exchangeable 
Share for one share of Common Stock, and in some cases we may redeem each 
Exchangeable Share for one share of Common Stock. We describe the process by 
which Exchangeable Shares may be exchanged for Common Stock on page 24 of 
this Prospectus under the heading "Plan of Distribution."

     Holders of Exchangeable Shares may exchange their Exchangeable Shares for
shares of our Common Stock immediately upon the completion of the combination of
PRI and Promis or at a later time. We are offering the shares of our Common
Stock on a continuous basis pursuant to Rule 415 under the Securities Act of
1933 only during the period when the registration statement relating to this
Prospectus is effective. We will bear the registration costs incurred in
connection with this offering.

     Our Common Stock is traded on the Nasdaq National Market under the 
symbol "PRIA." On December 22, 1998, the closing price of our Common Stock, 
as reported on the Nasdaq National Market, was $24.44 per share.

                              --------------------

             INVESTING IN THE SHARES INVOLVES A HIGH DEGREE OF RISK.

COMMISSION HAS APPROVED OR DISAPPROVED OF THESE SECURITIES OR DETERMINED IF THIS
PROSPECTUS IS TRUTHFUL OR COMPLETE. ANY REPRESENTATION TO THE CONTRARY IS A
CRIMINAL OFFENSE.

                         FORWARD-LOOKING STATEMENTS

     Certain statements in this Prospectus and in the documents incorporated by
reference into this Prospectus constitute "forward-looking statements" within
the meaning of Section 27A of the Securities Act and Section 21E of the Exchange
Act. Further, any statements contained in or incorporated into this Prospectus
that are not statements of historical fact may be deemed to be forward-looking
statements. In particular, statements in "Management's Discussion and Analysis
of Financial Condition and Results of Operations" relating to the Company's
shipment level and profitability, and the sufficiency of capital to meet working
capital and capital expenditures requirements, may be forward-looking
statements. Without limiting the foregoing, the words "expect," "anticipate,"
"plan," "believe," "seek," "estimate," "internal," "backlog" and similar
expressions are intended to identify such forward-looking statements. Such
statements are not guarantees of future performance, and involve certain risks,
uncertainties and assumptions that could cause the Company's future results to
differ materially from those expressed in any forward-looking statements made by
or on behalf of the Company. Many of such factors are beyond the Company's
ability to control or predict. Readers are accordingly cautioned not to place
undue reliance on forward-looking statements. The Company disclaims any intent
or obligation to update publicly any forward-looking statements whether in
response to new information, future events or otherwise. Important factors that
may cause the Company's actual results to differ from such forward-looking
statements include, but are not limited to, the risk factors discussed below.

                                  RISK FACTORS

     Investing in shares of our Common Stock involves significant risks. Because
you could lose the entire value of your investment, you should carefully
consider the following risks before deciding to invest in our Common Stock. We
are uncertain about the future of our business and, in preparing this document,
have made certain assumptions and projections. We generally use words like
"expect," "believe" and "intend" to indicate these assumptions and projections.
Our assumptions and projections could be wrong for many reasons, including the
reasons discussed in this section. We do not promise to notify you if we learn
that our assumptions or projections in this Prospectus are wrong.

TAXABILITY OF THE EXCHANGE  If you exchange your Exchangeable Shares for 
                            shares of our Common Stock, you may be required 
                            to pay tax on any gain you have under the laws 
                            of Canada and the United States. Your tax 
                            consequences can vary depending on:
                            
                            - where you are a resident for tax purposes

                            - whether you exchange your Exchangeable Shares 
                              by way of redemption or exchange

                            - the holding period for your Exchangeable Shares 

                            - the percentage of the total number of 
                              outstanding Exchangeable Shares held by Subco 
                              immediately after the exchange

                            CANADIAN TAX CONSIDERATIONS. If you are a 
                            Canadian resident holding Exchangeable Shares as 
                            capital property and deal at arm's length with 
                            and are not otherwise affiliated with us, and 
                            Exchangeable Shares are redeemed or retracted, 
                            you will generally be deemed to have received a 
                            dividend equal to the amount paid on the 
                            redemption or retraction less the paid-up capital 
                            of the Exchangeable Shares. You will also 
                            generally be deemed to have realized a capital 
                            gain (or capital loss) to the extent that your 
                            proceeds of disposition (net of reasonable costs 
                            of disposition) exceed (or are less than) your 
                            adjusted cost base for your shares. If you 
                            otherwise exchange your Exchangeable Shares for 
                            shares of our Common Stock, you will generally be 
                            considered to have realized a capital gain (or 
                            capital loss) equal to the amount, if any, by 
                            which the proceeds of disposition (net of 
                            reasonable costs of disposition) exceed (or are 
                            less than) your adjusted cost base for the 
                            Exchangeable Shares exchanged.

                            U.S.TAX CONSIDERATIONS. Except in limited 
                            circumstances, if you are a "United States 
                            person" for United States federal income tax 
                            purposes, you will generally recognize a gain or 
                            loss when you exchange your Exchangeable Shares 
                            for shares of our Common Stock. Your gain or loss 
                            will be equal to the difference between the fair 
                            market value of the shares of Common Stock you 
                            receive in the exchange and your basis in the 
                            Exchangeable Shares exchanged. The gain or loss 
                            will generally be a capital gain or loss, except 
                            that, with respect to any declared but unpaid 
                            dividends on the Exchangeable Shares, you may 
                            recognize ordinary income. A capital gain or loss 
                            will be a long-term capital gain or loss if your 
                            holding period for the Exchangeable Shares is 
                            more than one year at the time of the exchange. 
                            Under certain limited circumstances, the exchange 
                            of Exchangeable Shares for shares of our Common 
                            Stock may be characterized as a tax-free 
                            exchange. In particular, if you exchange your 
                            Exchangeable Shares for shares of our Common 
                            Stock pursuant to the Redemption Call Right or 
                            Liquidation Call Right (each as defined below), 
                            or at a time when our wholly owned subsidiary, 
                            1235949 Ontario, Inc., an Ontario corporation (or 
                            Subco), owns at least 80 percent of the issued 
                            and outstanding Exchangeable Shares, the exchange 
                            may be tax-free.

HOLDING AND DISPOSITION
OF COMMON STOCK             CANADIAN TAX CONSIDERATIONS. If you are a Canadian
                            resident, dividends that you receive (or are 
                            deemed to receive) on shares of our Common Stock 
                            must be included in your income. If you are an 
                            individual, the dividends will not be subject to 
                            the gross-up and dividend tax credit rules that 
                            normally apply to taxable dividends received from 
                            taxable Canadian corporations. If you are a 
                            corporation, the dividends will not be deductible 
                            in computing your taxable income. In certain 
                            circumstances you may be entitled to a foreign 
                            tax credit for any U.S. withholding tax paid on 
                            the dividends, subject to detailed rules in the 
                            Canadian Tax Act, including recently proposed 
                            amendments. Your cost amount for shares of our 
                            Common Stock that you receive on retraction, 
                            redemption or exchange of an Exchangeable Share 
                            will in general be equal to the fair market value 
                            of the shares of our Common Stock at the time of 
                            such event. When you dispose of shares of our 
                            Common Stock held by you as capital property, you 
                            will generally recognize a capital gain (or 
                            capital loss) equal to the amount, if any, by 
                            which the proceeds of disposition (net of 
                            reasonable costs of disposition) exceed (or are 
                            less than) your adjusted cost base of the shares 
                            of our Common Stock.

                            UNITED STATES TAX CONSIDERATIONS. If you are a 
                            Non-U.S. Holder, dividends that you receive with 
                            respect to shares of our Common Stock generally 
                            will be subject to United States withholding tax 
                            at a rate of 30 percent. This rate of withholding 
                            tax may be reduced if you are eligible for the 
                            benefits of an income tax treaty (generally 15 
                            percent on dividends paid to residents of Canada 
                            under the Tax Treaty). If you are a Non-U.S. 
                            Holder, you will generally not be subject to 
                            United States federal income tax on any gain that 
                            you recognize when you sell or exchange shares of 
                            our Common Stock, unless such gain is effectively 
                            connected with your conduct of a United States 
                            trade or business or, if you are an individual, 
                            you are present in the United States for 183 days 
                            or more and certain other conditions are 
                            satisfied.

                            WE STRONGLY URGE YOU TO CONSULT WITH YOUR TAX 
                            ADVISOR WITH RESPECT TO THE TAX CONSEQUENCES OF 
                            THE EXCHANGE OF YOUR EXCHANGEABLE SHARES FOR 
                            SHARES OF OUR COMMON STOCK. See "Plan of 
                            Distribution--Income Tax Considerations."

FOREIGN PROPERTY/QUALIFIED      
INVESTMENT ISSUES FOR
CANADIAN SHAREHOLDERS       If you hold your Exchangeable Shares through a 
                            trust governed by a registered retirement savings 
                            plan, a registered retirement income fund or a 
                            deferred profit sharing plan, you should know 
                            that the Exchangeable Shares will be "qualified 
                            investments" under the Canadian Tax Act as long 
                            as the Exchangeable Shares are listed on a 
                            prescribed stock exchange (which currently 
                            includes the Toronto Stock Exchange). If you are 
                            such a holder, your shares of our Common Stock 
                            will also be "qualified investments" under the 
                            Canadian Tax Act, as long as those shares are 
                            listed on a prescribed stock exchange (which 
                            currently includes Nasdaq). The Exchangeable 
                            Shares will not be "foreign property" under the 
                            Canadian Tax Act, as long as those shares are 
                            listed on a prescribed stock exchange in Canada. 
                            Our Common Stock will always be "foreign 
                            property" under the Canadian Tax Act. 
                            Accordingly, if you are

                            such a holder, you should consult your own
                            tax advisors prior to exchanging the trust's
                            Exchangeable Shares for shares of our Common
                            Stock. Investing in our Common Stock may
                            not be an acceptable investment for such
                            entities or may subject such entities to
                            additional taxes, fees or expenses.

DIFFERENCES IN CANADIAN 
AND U.S. TRADING MARKETS    The Exchangeable Shares are listed only on the 
                            Toronto Stock Exchange, and our Common Stock is
                            traded only on the Nasdaq National Market. We 
                            do not intend to list either the Exchangeable 
                            Shares or our Common Stock on any other stock 
                            exchange or market in the United States or 
                            Canada. Accordingly, the trading price of the 
                            Exchangeable Shares will be based upon the 
                            market for that stock on the Toronto Stock 
                            Exchange, and the trading price for our Common
                            Stock will be based upon the market for that 
                            stock on the Nasdaq National Market. We cannot 
                            assure you that the market price for our Common
                            Stock will be the same as, or even similar to,
                            the market price for the Exchangeable Shares.

CYCLICALITY OF 
SEMICONDUCTOR INDUSTRY      Our business depends heavily upon capital 
                            expenditures by semiconductor manufacturers,
                            particularly manufacturers that are opening or
                            expanding semiconductor fabrication facilities,
                            or "fabs." Whether these manufacturers undertake
                            capital expenditures in turn depends upon market
                            demand for their products and products that 
                            contain semiconductors. Historically, the 
                            semiconductor industry has been highly cyclical
                            and there have been periods of oversupply in the
                            market for semiconductors. Oversupply has caused
                            significantly reduced demand for capital 
                            equipment, including systems such as ours. We 
                            believe that the markets for newer generations 
                            of semiconductors will experience similar 
                            fluctuations, and that the recent high rate of 
                            technical innovation and resulting improvements
                            in the performance and price of semiconductor 
                            devices, which have driven much of the demand 
                            for our products, could slow or encounter 
                            limits.

                            In the last year, the semiconductor industry has
                            experienced a significant downturn, which has
                            seriously harmed our ability to sell our 
                            systems. Several of our customers have 
                            announced reductions in their planned capital 
                            expenditures, including expenditures for the 
                            construction or expansion of fabs. The recent 
                            downturn in the Asian markets has also affected
                            demand for semiconductor manufacturing 
                            equipment, including our systems. These and 
                            other factors have significantly reduced our
                            revenues and profitability in fiscal 1998. Our
                            total revenues for fiscal 1998 were $178.2
                            million, compared with total revenues of $213.6
                            million in fiscal 1997. In fiscal 1998, we
                            incurred a net loss of $23.9 million, compared
                            with net income of $26.6 million in fiscal 1997.

                            In July 1998, we announced a restructuring and
                            cost reduction plan and reduced our workforce by
                            approximately 15%. In fiscal 1998, we recorded a
                            pre-tax restructuring charge against earnings of
                            $5.6 million, including severance costs, costs
                            related to reduction in facilities and other
                            restructuring 


                                       5
<PAGE>

                            costs. In fiscal 1998, we also recorded a pre-tax
                            charge against earnings of $14.0 million for the
                            write-down of inventories to their net realizable
                            value and increases in the provision for warranty.

                            Any lengthy extension of the reduced demand for
                            semiconductor automation equipment would seriously
                            harm sales of our systems. If we take additional
                            cost-cutting measures in response to the downturn in
                            the semiconductor industry, we may be unable to
                            continue to invest in marketing, research,
                            development and engineering at the levels we think
                            necessary to maintain our competitive position. For
                            more information, see "--Management of Growth in 
                            Light of Fluctuating Demand."

LENGTHY SALES CYCLE         Our systems often have a lengthy sales cycle. Before
                            buying one of our systems, a prospective customer
                            must generally decide to upgrade or expand existing
                            facilities or to construct new facilities. These
                            undertakings are major decisions for most
                            prospective customers and typically involve
                            significant capital commitments and lengthy
                            evaluation and approval processes. In addition,
                            downturns in the semiconductor industry may cause
                            prospective customers to postpone decisions
                            regarding major capital expenditures, including
                            purchases of our systems. As a result of the length
                            of our typical sales cycle, we have difficulty
                            anticipating the timing and amount of specific
                            sales. Furthermore, we may spend significant amounts
                            of money and effort with no assurance that we will
                            make a sale.

SIGNIFICANT FLUCTUATIONS
IN OPERATING RESULTS        Many factors may cause our operating results to 
                            fluctuate significantly. Some of these factors are:

                            -   the timing of significant orders 
                            -   the gain or loss of any significant customer 
                            -   new product announcements and releases by us
                                or our competitors 
                            -   order cancellations and shipment rescheduling or
                                delays 
                            -   patterns of capital spending by our customers 
                            -   market acceptance of new and enhanced versions 
                                of our products 
                            -   changes in the pricing and the mix of products 
                                we sell
                            -   cyclicality in the semiconductor industry and 
                                the markets served by our customers
                            -   the timing of any acquisitions and related costs

                            In addition, the downturn in the Asian markets,
                            particularly in Korea, and uncertainties in demand
                            for automation equipment as the semiconductor
                            industry moves from 200mm to 300mm wafer processing
                            equipment have caused and may cause customers to
                            delay or cancel orders. For more information, see
                            "--Risks Associated With Asian Markets" and "--Delay
                            in Transition to 300mm Wafer Technology."

                            We derive a substantial portion of our revenues from
                            the sale of a relatively small number of our
                            systems. The purchase price of our systems generally
                            ranges from $3,000,000 to $15,000,000, and we
                            usually take more than one or two fiscal quarters to
                            deliver our systems. As a result, any delay in the
                            recognition of revenue for a single system could
                            harm our results for a given 


                                       6
<PAGE>

                            accounting period. If we delay a shipment near the
                            end of a fiscal period because, for example, the
                            customer reschedules or cancels its order or because
                            we encounter unexpected manufacturing difficulties,
                            our sales in that fiscal period could fall
                            significantly below our expectations. This could
                            seriously harm our business.

                            Our operating results also fluctuate because our
                            gross margins vary. Our gross margins vary for a
                            number of reasons, including:

                            -  the mix of products we sell
                            -  the average selling prices of products we sell
                            -  the costs to manufacture, market, service and 
                               support our new products and enhancements
                            -  the costs to customize our systems
                            -  our efforts to enter new markets

                            We typically charge a fixed price for our systems.
                            As a result, if the costs we incur in performing a
                            contract exceed our expectations, we generally
                            cannot pass those costs on to our customer. In
                            addition, we continue to invest in research and
                            development, capital equipment and extensive ongoing
                            customer service and support capability worldwide.
                            These investments create significant fixed costs
                            that we may be unable to reduce rapidly if we do not
                            meet our sales goals. Moreover, if we lack a
                            significant backlog of orders for an extended period
                            of time, we may have difficulty planning our future
                            production and inventory levels, which could also
                            cause fluctuations in our operating results.

                            As a result of these factors, we believe that
                            period-to-period comparisons of our revenues and
                            results of operations are not necessarily
                            meaningful. You should not rely on these comparisons
                            as indicators of our future performance.

CUSTOMER CONCENTRATION      Historically, we have derived a significant portion 
                            of our revenues from sales to a limited number of
                            customers. We expect this trend to continue for the
                            foreseeable future. In fiscal 1996, 1997 and 1998,
                            sales to our three largest customers accounted for
                            40%, 47% and 41% of our total sales,
                            respectively. In those years, one customer, Intel
                            Corporation, accounted for 29%, 36% and 22% of
                            our net revenue, respectively. Our largest
                            customers can change from year to year, as customers
                            complete large fabs and initiate new projects.

                            None of our customers has any long-term obligation
                            to continue to purchase our products or services,
                            and any customer could reduce or cease ordering our
                            products or services. We believe that sales to some
                            of our customers will decrease in the near future as
                            they complete their current purchases for new or
                            expanded fabs. When a customer cancels an order, our
                            sales contract generally allows us to recover our
                            out-of-pocket expenses and a portion of our
                            anticipated profits from the sale. Because of the
                            long sales cycle for our products, we may have
                            difficulty in quickly replacing orders that our
                            customers cancel or reduce. Our failure to obtain
                            large orders from new or existing customers could
                            seriously harm our business. In the past, our
                            customers have sometimes failed to place orders we
                            expected or have delayed or canceled

                            delivery schedules as a result of changes in their
                            requirements. Order deferrals or cancellations can
                            seriously harm our business.

RISKS ASSOCIATED WITH
ASIAN MARKETS               The current economic downturn in certain Asian 
                            countries has adversely affected, and could continue
                            to adversely affect, the worldwide semiconductor
                            industry and our business. According to industry
                            analysts, as a result of the recession in Japan, as
                            well as currency fluctuations and other problems in
                            other Asian countries, Asian consumers have slowed
                            purchases of personal computers, cellular phones and
                            other products that use semiconductors. The
                            reduction in demand for semiconductors has led and
                            could continue to lead semiconductor manufacturers,
                            both in Asia and the United States, to build fewer
                            new fabs and undertake fewer capital improvement
                            projects in their existing fabs. As a result, we
                            have experienced, and could continue to experience,
                            delays or cancellations of orders from our
                            customers. Such delays or cancellations could
                            seriously harm our business.

                            Despite the financial uncertainty in these Asian
                            countries, we believe that our continued presence in
                            Asian markets will be important to our long-term
                            future financial performance. Accordingly, we expect
                            to invest significant resources in increasing our
                            presence in Asia. These markets, which include
                            Korea, Taiwan, Singapore, China and, most
                            significantly, Japan, represent a substantial
                            percentage of the worldwide semiconductor
                            manufacturing capacity. In the Japanese market
                            (including fabs operated outside Japan by Japanese
                            semiconductor manufacturers), we may suffer from
                            more disadvantages than our Japanese competitors,
                            many of whom have longstanding collaborative
                            relationships with Japanese and other Asian
                            semiconductor manufacturers. Accordingly, we may be
                            unable to increase sales in the Asian semiconductor
                            markets. For more information, see "--International
                            Operations" and "--Competition."

DELAY IN TRANSITION TO 
300MM WAFER TECHNOLOGY      Currently, the most widely used semiconductor 
                            manufacturing process handles 200mm semiconductor
                            wafers. Industry analysts expect that, in order to
                            increase manufacturing efficiencies and reduce
                            costs, semiconductor manufacturers will begin using
                            300mm wafers. We believe that the expected
                            transition to 300mm manufacturing technology
                            represents an important opportunity for us because
                            customers will need to build entirely new fabs and
                            develop entirely new process tools and automation
                            systems to process 300mm wafers. In addition, we
                            believe that ergonomic, safety and cost factors will
                            make increased levels of factory-wide automation a
                            practical necessity in new 300mm fabs.

                            For this reason, we have invested, and are
                            continuing to invest, substantial resources to
                            develop new systems and technologies to automate the
                            processing of 300mm wafers. However, the industry
                            transition from 200mm to 300mm manufacturing
                            technology is occurring more slowly than we
                            expected, partly as a result of the recent reduction
                            in demand for semiconductors. Although pilot
                            projects are underway, no new 300mm fab is yet under
                            construction. Any

                            significant delay in the adoption of 300mm
                            manufacturing technology, or the failure of such
                            adoption to occur, could significantly reduce our
                            results of operations. Moreover, any delay in the
                            transition to 300mm technology could permit our
                            competitors to introduce 300mm products competitive
                            with or superior to our systems.

MANAGEMENT OF GROWTH IN
LIGHT OF FLUCTUATING 
DEMAND                      Our business is requiring us to hire substantial 
                            numbers of new employees, particularly employees
                            with technical backgrounds for our engineering and
                            technical support staffs. The market for these
                            employees is becoming increasingly competitive, and
                            we have occasionally experienced delays in meeting
                            our staffing requirements. Our failure or inability
                            to recruit, retain and train adequate numbers of
                            qualified personnel on a timely basis would
                            adversely affect our ability to develop,
                            manufacture, install and support our systems.

                            If the semiconductor industry resumes its growth, we
                            may have to design and manufacture our systems in
                            larger volumes than we do now. If demand for our
                            products increases rapidly, we may have difficulty
                            increasing our production capacity while maintaining
                            our standards of quality and reliability, and
                            delivery times for our systems may increase. If we
                            fail to meet a customer's delivery or performance
                            criteria, we could lose business from that customer,
                            cause long-term damage to our reputation and have
                            higher warranty and service costs. Any of these
                            results could seriously harm our business. Further,
                            if we are unable to expand our existing
                            manufacturing capacity to meet demand, a customer's
                            placement of a large order requiring the development
                            and delivery of flexible factory automation systems
                            during a particular period might deter other
                            semiconductor manufacturers from placing similar
                            orders with us for the same period. For more
                            information, see "--Significant Fluctuations in
                            Operating Results."

                            Our systems, procedures, controls and staffing may
                            not be adequate to support any rapid growth in our
                            operations, if any. Our failure to respond
                            effectively to fluctuating demand for our products
                            and to manage our future growth, if any, could
                            seriously harm our business.

EFFECTS OF RECENT
ACQUISITION ACTIVITY        We are continuing to integrate the operations of 
                            Equipe Technologies, Inc. and its European
                            distributor, Chiptronix Handling Systems GmbH, which
                            we acquired in January 1998 and May 1998,
                            respectively. Equipe develops, manufactures and
                            supplies atmospheric wafer and substrate handling
                            robots, pre-aligners and controllers.

                            In February 1999, we expect to acquire Promis 
                            Systems Corporation Ltd., a Canadian corporation.
                            Promis is based in Toronto, Ontario and develops,
                            markets and maintains software products used by
                            large-scale manufacturers, such as semiconductor
                            manufacturers and precision electronics
                            manufacturers, to optimize their manufacturing
                            processes and ensure compliance with


                                       9
<PAGE>

                            mandatory specifications. We are only now beginning
                            to take steps to integrate our operations with
                            those of Promis.

                            We may not be able to absorb and effectively manage
                            the acquisitions of Equipe, Chiptronix and Promis or
                            successfully develop, market and sell the products
                            of Equipe and Promis. These acquisitions and any
                            future acquisitions also pose additional risks,
                            including:

                            -  diversion of our management's attention 
                            -  loss of key employees of the acquired company 
                            -  interruptions in the sales efforts of the 
                               acquired company 
                            -  failure to integrate financial and accounting 
                               systems successfully 
                            -  significant acquisition and integration expenses 
                            -  assumption of legal and other liabilities and 
                               risks 
                            -  entry into markets in which we have little or no 
                               prior experience

                            Any of these factors could seriously harm our
                            business. Moreover, an acquisition may not produce
                            the revenues, earnings or business synergies that we
                            anticipated, and an acquired product, service or
                            technology might not perform as we expected. Any
                            such poor performance could cause customer
                            dissatisfaction and damage our reputation.

                            To pay for an acquisition, we might use capital
                            stock or cash, or incur long-term indebtedness. If
                            we use capital stock, our existing stockholders
                            might experience dilution of their ownership
                            interests. If we use our cash reserves or
                            significant debt financing, our liquidity will be
                            reduced.

INTERNATIONAL OPERATIONS    In the last three fiscal years,  we have 
                            derived a substantial percentage of our revenues
                            from customers outside the United States. In fiscal
                            1996, 1997 and 1998, international sales accounted
                            for 15%, 46% and 33% of our total revenues,
                            respectively. We intend to maintain our presence in
                            European markets and to expand our presence in Asian
                            markets. Accordingly, we anticipate that
                            international sales will account for a significant
                            portion of our net sales in the foreseeable future.
                            We will need to devote significant management
                            attention and financial resources to our
                            international expansion plans.

                            Our international operations are subject to
                            additional risks, such as the following:

                            -  unexpected changes in trading policies, 
                               regulatory requirements, exchange rates, tariffs 
                               and other barriers
                            -  unstable political and economic environments
                            -  greater difficulties in collecting accounts

                            Although our international sales are primarily
                            denominated in U.S. dollars, currency exchange
                            fluctuations could nonetheless make us less
                            price-competitive than foreign manufacturers. If our
                            international sales increase as a percentage of our
                            total revenues, these factors could have a more
                            pronounced effect on our results of operations. In
                            any event, any of these factors could cause serious
                            harm to our business. For more information, see
                            "--Risks Associated With Asian Markets" and
                            "--Limited Intellectual Property Protection."

COMPETITION                 We compete intensely with one principal competitor, 
                            the clean automation division of Daifuku Co., Ltd.,
                            a large Japanese manufacturer of factory automation
                            systems. We also compete with Shinko Electronics
                            Company, Murata Machinery Ltd. and a number
                            of foreign and domestic manufacturers of
                            equipment used to automate the process of
                            semiconductor manufacturing. Our Equipe division 
                            competes with a number of wafer-handling robotics 
                            companies including in-house organizations of 
                            process tool manufacturers that develop their own 
                            automation, as well as other smaller robotics 
                            companies. Our software division competes with a 
                            number of suppliers of automated scheduling and
                            planning software. We believe that competition in
                            our industry is likely to intensify. Our competitors
                            could develop new products with superior performance
                            features or a better price, and new competitors
                            could enter our markets and develop such products.
                            We also believe that, once a semiconductor
                            manufacturer selects a particular vendor's
                            equipment, the manufacturer will generally
                            rely upon that equipment for the specific production
                            line application and will frequently attempt to
                            fulfill its other capital equipment needs from the
                            same vendor. Accordingly, we expect to have
                            difficulty selling to potential customers that have
                            selected a competitor's equipment, and we expect
                            that difficulty to last for a significant period of
                            time. In addition, the expected transition to 300mm
                            technology may cause new competitors to enter our
                            markets and may diminish our competitive advantage
                            with customers for whom we are the incumbent
                            supplier of automation equipment. In the face of
                            increased competition, we may need to lower our
                            prices, which could seriously harm our business.

RAPID TECHNOLOGICAL CHANGE  Technology changes rapidly in the semiconductor 
                            manufacturing industry, and our competitors
                            frequently introduce more advanced products or
                            product enhancements. Our ability to compete in our
                            markets will depend, in part, on our ability to
                            develop and introduce more advanced systems at
                            competitive prices and on a cost-effective basis so
                            as to enable our customers to integrate them into
                            their operations either before or as they begin
                            volume product manufacturing. If our competitors
                            introduce new products or product enhancements, our
                            sales could decline and our existing products could
                            lose market acceptance. Our success in developing,
                            introducing, selling and supporting more advanced
                            systems depends upon many factors, including:

                            -  component selection
                            -  timely and efficient completion of product design
                               and development 
                            -  timely and efficient implementation of 
                               manufacturing and assembly processes 
                            -  software development 
                            -  product performance in the field 
                            -  effective sales, marketing, service and project 
                               management

                            Because we must commit resources to product
                            development well in advance of sales, our product
                            development decisions must anticipate technological
                            advances in semiconductor manufacturing by leading
                            semiconductor manufacturers. We may not be
                            successful in that effort. Our inability to select,
                            develop, manufacture and market new systems or
                            enhance our existing systems could cause us to lose
                            our competitive position and could seriously harm
                            our business.

PRODUCT DEVELOPMENT DELAY   Because our systems are complex and have a large 
                            number of components, we can experience significant
                            delays between our initial introduction of a system
                            and our volume production of that system. We have
                            occasionally experienced delays in the introduction
                            of certain of our systems and enhancements, as well
                            as certain technical and manufacturing difficulties
                            with those systems and enhancements. We could
                            experience similar delays and difficulties in the
                            future. In addition, we must customize some of our
                            systems to meet the customer's site or operating
                            requirements. Our inability to complete the
                            development or meet the technical specifications of
                            any of our new systems or enhancements or to
                            manufacture and ship these systems or enhancements
                            in volume in a timely manner could impair our
                            relationships with our customers and seriously harm
                            our business. In addition, we may incur substantial
                            unanticipated costs to ensure that our new products
                            function properly and reliably early in their life
                            cycle. These costs could be, for example, greater
                            than expected installation and support costs or
                            increased materials costs as a result of expedited
                            charges. We may not be able to pass these costs on
                            to our customers. Any of these events could
                            seriously harm our business.

SOLE OR LIMITED SOURCES
OF SUPPLY                   For certain components or specialized processes 
                            (such as painting of system cabinets and enclosures)
                            that we use in our products, we depend on or have
                            available only one or a few suppliers. We have not
                            experienced any significant disruption or delay in
                            obtaining components we need for our products, and
                            we believe in most instances we could develop other
                            sources of supply or qualify other vendors for these
                            components or processes. Nonetheless, we could
                            experience such disruption or delay and may not be
                            able to develop alternatives in a timely manner. If
                            we are unable to obtain adequate deliveries of
                            components for our products for an extended period
                            of time, we may have to pay more for inventory,
                            parts and other supplies, seek alternative sources
                            of supply or delay shipping products to our
                            customers. We could also damage our relationships
                            with customers. Any such increased costs, delays in
                            shipping or damage to customer relationships could
                            seriously harm our business.

LIMITED INTELLECTUAL
PROPERTY PROTECTION         Our success depends to a significant degree upon our
                            proprietary technologies. To protect our proprietary
                            technologies, we rely primarily upon employee and
                            third-party non-disclosure agreements, trade secret,
                            copyright and trademark laws, and license
                            agreements. Wherever appropriate, we also seek to
                            patent our technologies. We hold several patents and
                            patent applications, including a patent relating to
                            certain key elements of our AeroTrak monorail
                            system, which forms an important component of our
                            interbay automation systems. We

<PAGE>

                            attempt to protect the source code versions of our
                            software as trade secrets and as unpublished
                            copyrighted works. We believe, however, that our
                            financial performance will depend more upon our
                            innovation and technological expertise and the
                            capabilities of our employees than upon the
                            protection of our intellectual property rights.

                            The steps we have taken to protect our proprietary
                            technology may be inadequate. Existing trade secret,
                            copyright and trademark laws offer only limited
                            protection. Our patents could be challenged,
                            invalidated or circumvented, and the rights we have
                            under our patents could provide no competitive
                            advantages. Other companies could independently
                            develop similar or superior technology without
                            violating our proprietary rights. Any
                            misappropriation of our technology or the
                            development of competitive technology could
                            seriously harm our business. If we have to resort to
                            legal proceedings to enforce our intellectual
                            property rights, the proceedings could be burdensome
                            and expensive and could involve a high degree of
                            risk. In addition, the laws of some foreign
                            countries do not protect our proprietary
                            technologies to the same extent as the laws of the
                            United States.

                            Third parties could claim that our products or
                            technology infringe their patents or other
                            proprietary rights. Any such claim could cause us to
                            incur substantial costs defending against the claim,
                            even if the claim is invalid, and could distract our
                            management from our business. Furthermore, a party
                            making such a claim could secure a judgment that
                            requires us to pay substantial damages. A judgment
                            could also include an injunction or other court
                            order that could prevent us from selling our
                            products. Any of these events could seriously harm
                            our business.

                            If anyone asserts a claim against us relating to
                            proprietary technology or information, we might seek
                            to license their intellectual property or to develop
                            non-infringing technology. We might not be able to
                            obtain a license on commercially reasonable terms or
                            on any terms. Alternatively, our efforts to develop
                            non-infringing technology could be unsuccessful. Our
                            failure to obtain the necessary licenses or other
                            rights or to develop non-infringing technology could
                            prevent us from selling our products and, therefore,
                            could seriously harm our business.

ENVIRONMENTAL REGULATIONS   We are subject to a variety of governmental 
                            regulations relating to the use, storage, handling,
                            manufacture and disposal of toxic or other hazardous
                            substances we use to manufacture our products. We
                            use small quantities of lubricants, adhesives,
                            solvents and cleaners in connection with our
                            manufacturing and assembly operations. We believe
                            that our storage, use and disposal of these
                            materials complies in all material respects with
                            applicable governmental regulations, and that we
                            have obtained all necessary environmental permits to
                            conduct our business. Our failure to control the
                            use, disposal or storage of, or to adequately
                            restrict the discharge of, hazardous or toxic
                            substances could subject us to significant
                            liabilities. Any such liability could materially
                            harm our business.

DEPENDENCE ON KEY 
PERSONNEL                   Our future success depends significantly on the 
                            skills, experience and efforts of our key executive
                            officers and employees. We depend heavily upon the
                            continued contributions of our founder, Chairman of
                            the Board and Treasurer, Mordechai Wiesler, our
                            President and Chief Executive Officer, Mitchell G.
                            Tyson, and other officers and key personnel. Many of
                            these individuals would be difficult to replace.
                            Although we maintain key person life insurance on
                            Messrs. Wiesler and Tyson, the loss of Mr. Wiesler,
                            Mr. Tyson or any other key person could seriously
                            harm our business. In addition, our future financial
                            performance will depend in part upon our ability to
                            attract and retain other qualified management,
                            engineering, financial, technical, marketing and
                            sales, and support personnel for our operations.
                            Competition for these employees is intense and we
                            may be unable to attract or retain them. Our failure
                            to attract or retain these employees could seriously
                            harm our business.

YEAR 2000                   Many existing computer systems and software products
                            do not properly recognize dates after December 31,
                            1999. This "Year 2000" problem could result in
                            miscalculations, data corruption, system failures or
                            disruptions of operations. These disruptions could
                            include an inability to process transactions, send
                            invoices or engage in normal business activities.
                            The Year 2000 problem could also affect embedded
                            systems such as building security systems, machine
                            controllers, telephone switches and other equipment.
                            As a result, many companies may need to upgrade or
                            replace their computer systems, software and other
                            equipment.

                            We have established a centrally coordinated project
                            team, including representatives from each of our
                            divisions, to determine the Year 2000 readiness of
                            our products, business processes and systems and 
                            products of our suppliers and other third parties. 
                            We have reviewed all equipment and software that we
                            are currently marketing or that is already installed
                            at customer sites for Year 2000 readiness. We expect
                            to complete all internal and field testing and
                            upgrades of current and installed products by early
                            1999. We cannot presently estimate the total cost
                            of this testing and upgrade process but we do not
                            expect it to be material. We are also assessing our
                            internal information technology, or IT, systems,
                            including business information systems, systems we
                            use in our manufacturing and service operations, and
                            systems that provide electronic interfaces with our
                            business associates and customers, and internal 
                            non-IT systems, including telecommunications 
                            systems, security systems and utilities, to ensure
                            that our operations are not interrupted by Year 2000
                            issues. We expect to have addressed all internal
                            Year 2000 issues identified in this process by the
                            end of June 1999.

                            We also rely on third-party vendors for certain
                            equipment and software that may not be Year 2000
                            compliant. We are working closely with these
                            third-party vendors to determine the extent of their
                            Year 2000 compliance. The failure of the equipment
                            and software of these vendors to be Year 2000
                            compliant could substantially disrupt our normal
                            operations. Any such disruption, or the costs of
                            updating or replacing any of our equipment and
                            software, could seriously harm our business. The
                            failure of systems maintained by our vendors to be
                            Year 2000 compliant could cause us to incur
                            significant expenses to remedy any problems or could
                            otherwise seriously harm our business.

                            Based on our investigations to date, we do not
                            expect the total cost of our Year 2000 assessment
                            and remediation program to be significant. However,
                            we might discover unanticipated Year 2000 errors or
                            defects in our products, internal computer systems,
                            software and other equipment. We could also fail to
                            complete our Year 2000 assessment and remediation
                            programs on a timely basis and the costs of such
                            programs may be greater than expected. The resulting
                            disruption of our operations and additional costs
                            could seriously harm our business.

VOLATILITY OF STOCK PRICE   The market price of our Common Stock has fluctuated 
                            widely and may continue to do so. Many factors could
                            cause the market price of our Common Stock to rise
                            and fall. Some of these factors are:

                            -  variations in our quarterly results of operations
                            -  announcements of technological innovations
                            -  introduction of new products or new pricing 
                               policies by us or our competitors 
                            -  trends in the semiconductor manufacturing
                               industry 
                            -  acquisitions or strategic alliances by us or 
                               others in our industry 
                            -  the hiring or departure of key personnel 
                            -  changes in accounting principles 
                            -  changes in estimates of our performance or
                               recommendations by financial analysts 
                            -  market conditions in the industry and the economy
                               as a whole

                            In addition, the stock market has recently
                            experienced extreme price and volume fluctuations.
                            These fluctuations have particularly affected the
                            market prices of the securities of many high
                            technology companies. These broad market
                            fluctuations could adversely affect the market price
                            of our Common Stock. When the market price of a
                            stock has been volatile, holders of that stock have
                            often instituted securities class action litigation
                            against the company that issued the stock. If any of
                            our stockholders brought such a lawsuit against us,
                            we could incur substantial costs defending the
                            lawsuit. The lawsuit could also divert the time and
                            attention of our management. Any of these events
                            could seriously harm our business.

                            When we acquired Equipe, Chiptronix and two related
                            companies, we issued 4,469,016 shares of our Common
                            Stock to the former stockholders of those companies.
                            Immediately after they were issued, these shares
                            were "restricted securities" for purposes of Rule
                            144 under the Securities Act, and will be eligible
                            for sale in the public market pursuant to Rule 144
                            commencing in January 1999. We have already
                            registered approximately 31% of these shares for
                            sale in the public market. We may be required to
                            register the remaining shares for sale in the public
                            market. The sale of substantial amounts of these
                            shares in the public market could adversely affect
                            the market price of our Common Stock.

ANTI-TAKEOVER EFFECT OF
CHARTER PROVISIONS, BY-LAWS
STOCKHOLDER RIGHTS PLAN
AND MASSACHUSETTS LAW       Our basic corporate documents, our Stockholder 
                            Rights Plan and Massachusetts law contain provisions
                            that might enable our management to resist an
                            attempt to take over our company. For example, the
                            Board of Directors of PRI (the "Board of Directors"
                            or the "Board") can issue shares of Common Stock and
                            Preferred Stock without stockholder approval, and
                            the Board could issue stock to dilute and adversely
                            affect various rights of a potential acquiror. The
                            Board could use other provisions to discourage,
                            delay or prevent a change in the control of our
                            company or a change in our management. These
                            provisions might also discourage, delay or prevent
                            an acquisition of our company at a price that you
                            may find attractive. These provisions could also
                            make it more difficult for you and our other
                            stockholders to elect directors and take other
                            corporate actions. These provisions could limit the
                            price that investors might be willing to pay for
                            shares of our Common Stock.

                                   THE COMPANY

     We are a leading supplier of factory automation systems for semiconductor
manufacturers and OEM equipment suppliers. We combine advanced robotics
technology with material handling systems and a broad array of integrated
software to automate the manufacturing of integrated circuits. Our mission is to
provide integrated solutions of hardware, software and services that optimize
the flow of silicon wafers throughout the semiconductor fabrication facility, or
fab, improving the productivity of semiconductor manufacturing. Our products
consist of overhead monorail wafer transportation systems; work-in-process wafer
stockers and reticle stockers; tool automation systems; material control
software and scheduling and planning software; and factory simulation and other
services, including project management and on-site support. Our automated
material handling solutions increase process tool utilization and throughput by
optimizing the flow of wafers to and from process tools throughout the fab.

      In North America, we sell our products through a direct sales force
operating out of our headquarters in Billerica, Massachusetts and our regional
offices in California, Texas and Oregon. Outside North America, we sell and
support our products through our direct sales and technical support organization
with offices in the United Kingdom, France, the Netherlands, Germany, Ireland,
Israel, Italy, Switzerland, Taiwan, South Korea, Singapore, and Japan.

     Our principal executive offices are located at 805 Middlesex Turnpike,
Billerica, Massachusetts 01821-3986, and our telephone number is (978) 670-4270.
Our company was incorporated in Massachusetts in 1972 under another name and we
began our present business in 1982.

                                  RECENT EVENTS

     On November 24, 1998, PRI agreed to acquire Promis pursuant to the terms 
of a Combination Agreement (the "Combination Agreement") among PRI, Promis 
and Subco. The acquisition, which is intended to be accounted for as a 
pooling of interests, is expected to be completed during the first quarter of 
1999, subject to, among other things, regulatory approvals and approval of 
the shareholders of Promis.


                                       16
<PAGE>


     Promis develops, markets and maintains software products used by 
large-scale manufacturers, such as semiconductor and precision electronics 
manufacturers, to optimize their manufacturing processes and ensure 
compliance with mandatory specifications. Promis' software is "mission 
critical" in that large-scale manufacturers would be unable to effectively 
operate their facilities without its use or the use of similar software.

     Promis' software offerings operate in real-time and are designed for use by
manufacturers whose raw materials or components are processed in distinct units,
permitting work-in-progress and finished goods to be tracked by lots. Promis'
software products are designed to assist in the planning, execution and control
of manufacturing operations and thereby enhance the competitiveness of such
manufacturing users, by allowing them to achieve higher product quality, faster
output and lower productions costs.

                                 USE OF PROCEEDS

     Because the shares of Common Stock offered hereby will be issued upon
exchange or redemption of the Exchangeable Shares, the Company will receive no
net cash proceeds upon such issuance.

                          DESCRIPTION OF CAPITAL STOCK

     The authorized capital stock of the Company consists of 50,000,000 
shares of Common Stock and 400,000 shares of Preferred Stock, par value $.01 
per share (the "Preferred Stock"), of which 250,000 shares have been 
designated as Series A Participating Cumulative Preferred Stock, par value 
$.01 per share (the "Series A Preferred Stock"). In connection with the 
combination of PRI and Promis, one share of undesignated Preferred Stock of 
the Company will be designated as Special Voting Preferred Stock, par value 
$.01 per share (the "Voting Share").

COMMON STOCK

     As of December 18, 1998, there were 19,946,524 shares of Common Stock
outstanding. Holders of Common Stock are entitled to one vote per share held of
record on all matters to be voted upon by the stockholders of the Company.
Subject to preferences that may be applicable to the holders of outstanding
shares of Preferred Stock, if any, the holders of Common Stock are entitled to
receive such lawful dividends as may be declared by the Board of Directors. In
the event of the liquidation, dissolution or winding up of the Company, and
subject to the rights of the holders of outstanding shares of Preferred Stock,
if any, the holders of shares of Common Stock are entitled to receive pro rata
all of the remaining assets of the Company available for distribution to its
stockholders.

PREFERRED STOCK

     As of December 18, 1998, there were no shares of Preferred Stock
outstanding. The Board of Directors is authorized, subject to limitations
prescribed by Massachusetts law, to provide for the issuance of Preferred Stock
in one or more series, to establish from time to time the number of shares to be
included in each such series, to fix or alter the rights, preferences and
privileges of the shares of each wholly unissued series and any restrictions
thereon, and to increase or decrease the number of shares of any such series
(but not below the number of shares of such series then outstanding) without any
further vote or action by the stockholders. The issuance of Preferred Stock or
of rights to purchase Preferred Stock could be used to discourage an unsolicited
acquisition proposal.

STOCKHOLDER RIGHTS PLAN

     On December 7, 1998, the Board of Directors declared a distribution of one
right (a "Right") on each outstanding share of Common Stock of the Company. The
Rights were issued to the holders of record of Common Stock outstanding on
December 9, 1998, and will be issued, except as described below, with respect to
shares of 


                                       17
<PAGE>


Common Stock issued before the Distribution Date (as defined below) and, in
certain circumstances, with respect to shares of Common Stock issued after the
Distribution Date. Each Right, when it becomes exercisable as described below,
will entitle the registered holder to purchase from the Company one
one-hundredth (1/100) of a share of Series A Preferred Stock at a price of $140
(the "Purchase Price"). The description and terms of the Rights are set forth in
a Rights Agreement dated as of December 9, 1998 (the "Rights Agreement") between
the Company and State Street Bank and Trust Company, as Rights Agent (the
"Rights Agent").

     Until the earlier of (i) the date on which the Company first publicly
announces that a person or group (including any affiliate or associate of such
person or group) has acquired, or has obtained the right to acquire, beneficial
ownership of 20% or more of the outstanding Common Stock of the Company,
including Common Stock issuable upon the exchange or redemption of Exchangeable
Shares, (such person or group being called an "Acquiring Person") or (ii) the
date, if any, as may be designated by the Board of Directors following the
commencement of, or first public disclosure of an intent to commence, a tender
or exchange offer for outstanding Common Stock of the Company which could result
in the offeror becoming the beneficial owner of 20% or more of the outstanding
Common Stock of the Company, including Common Stock issuable upon the exchange
or redemption of Exchangeable Shares, (the earlier of such dates being called
the "Distribution Date"), the Rights will be evidenced by the certificates for
Common Stock registered in the names of the holders thereof (which certificates
for Common Stock will also be deemed to be Right Certificates, as defined below)
and not by separate Right Certificates. Accordingly, until the Distribution
Date, the Rights will be transferred with and only with the Common Stock.

     As soon as practicable following the Distribution Date, separate
certificates evidencing the Rights ("Right Certificates") will be mailed to
holders of record of the Common Stock as of the close of business on the
Distribution Date (and to each initial record holder of certain Common Stock
originally issued after the Distribution Date), and such separate Right
Certificates alone will thereafter evidence the Rights. The Rights are not
exercisable until the Distribution Date and will expire on December 9, 2008 (the
"Expiration Date"), unless earlier redeemed by the Company as described below.

     To preserve the actual or potential economic value of the Rights, the
number of shares of Series A Preferred Stock or other securities issuable upon
exercise of a Right, the Purchase Price and Redemption Price and the number of
Rights associated with each outstanding share of Common Stock are all subject to
adjustment by the Board of Directors as provided in the Rights Agreement in the
event of any change in the Company's Common Stock or Series A Preferred Stock,
whether by reason of stock dividends, stock splits, recapitalizations, mergers,
consolidations, combinations or exchanges of securities, split-ups, split-offs,
spin-offs, liquidations or any other similar changes in capitalization, any
distribution or issuance of cash, assets, evidences of indebtedness or
subscription rights, options or warrants to holders of Common Stock or Series A
Preferred Stock, as the case may be (other than distribution of the Rights or
regular quarterly cash dividends), or otherwise.

     The shares of Series A Preferred Stock are authorized to be issued in
fractions which are an integral multiple of one one-hundredth (1/100) of a share
of Series A Preferred Stock. The Company may, but is not required to, issue
fractions of shares upon the exercise of the Rights, and, in lieu of fractional
shares, the Company may issue certificates or utilize a depository arrangement
as provided by the terms of the Series A Preferred Stock and, in the case of
fractions other than one one-hundredth (1/100) of a share of Series A Preferred
Stock or integral multiples thereof, may make a cash payment based on the market
price of such shares.

     Upon a person or a group becoming an Acquiring Person, the Rights will
entitle each holder of a Right to purchase, for the Purchase Price, that number
of one one-hundredths (1/100) of a share of Series A Preferred Stock equivalent
to the number of shares of Common Stock which at the time of the transaction
would have a market value of twice the Purchase Price.


                                       19

     If the Company is acquired in a merger or other business combination of 50%
or more of its assets or assets representing 50% or more of its earning power
are sold, leased, exchanged or otherwise transferred (in one or more
transactions) to a publicly traded corporation, each Right will entitle its
holder to purchase, for the Purchase Price, that number of common shares of such
corporation which at the time of the transaction would have a market value of
twice the Purchase Price. If the Company is acquired in a merger or other
business combination of 50% or more of its assets or assets representing 50% or
more of the earning power of the Company are sold, leased, exchanged or
otherwise transferred (in one or more transactions) to an entity that is not a
publicly traded corporation, each Right will entitle its holder to purchase, for
the Purchase Price, at such holder's option, (i) the number of shares of such
entity (or, at such holder's option, of the surviving corporation in such
acquisition, which could be the Company) which at the time of the transaction
would have a book value of twice the Purchase Price or (ii) if such entity has
an affiliate which has publicly traded common shares, that number of common
shares of such affiliate which at the time of the transaction would have a
market value of twice the Purchase Price.

     Any Rights that are at any time beneficially owned by an Acquiring Person
(or any affiliate or associate of an Acquiring Person) will be null and void and
nontransferable. Any holder of any such Right (including any purported
transferee or subsequent holder) will not have any right to exercise or transfer
any such Right.

     At any time after a person or a group becomes an Acquiring Person, the
Board of Directors may exchange all or part of the then-outstanding Rights
(other than Rights that have become null and void and nontransferable as
described above) for consideration per Right consisting of one-half of the
securities that otherwise would have been issuable to the holder of each Right
upon exercise of the Right. The Board of Directors may also issue, in
substitution for shares of Series A Preferred Stock, shares of Common Stock
having an equivalent market value to the shares of Series A Preferred Stock if,
at such time, the Company has a sufficient number of shares of Common Stock
issued but not outstanding or authorized but unissued.

     At any time prior to the earlier of the Expiration Date or the first public
announcement by the Company that a person has become an Acquiring Person, the
Board of Directors may redeem all, but not less than all, of the Rights at a
price (in cash or shares of Common Stock or other securities of the Company
deemed by the Board of Directors to be at least equivalent in value) of $.001
per Right (the "PRI Right Redemption Price").

     If the Board of Directors elects to redeem the Rights, the Company will 
announce the redemption, the right to exercise the Rights will terminate and 
the only right of the holders of Rights will be to receive the PRI Right 
Redemption Price.

     Until a Right is exercised, the holder thereof, as such, will have no
rights as a stockholder of the Company, including, without limitation, the right
to vote or to receive dividends.

     At any time prior to the Distribution Date, the Company may, without the 
approval of any holder of the Rights, supplement or amend any provision of 
the Rights Agreement (including the date on which the Distribution Date will 
occur, the time during which the Rights may be redeemed or the terms of the 
Series A Preferred Stock), except that the Company may not supplement or 
amend the Rights Agreement to reduce the PRI Right Redemption Price or 
provide for an earlier Expiration Date.

     The Rights have certain anti-takeover effects. The Rights will cause
substantial dilution to a person or group that attempts to acquire the Company
without conditioning the offer on substantially all the Rights being acquired.
The Rights will not interfere with any merger or other business combination with
a third party approved by the Board of Directors because the Board of Directors
may, at its option, at any time prior to any person becoming an Acquiring
Person, redeem the then-outstanding Rights at the Redemption Price.

SERIES A PREFERRED STOCK

     As of December 18, 1998, there were no shares of Series A Preferred Stock
outstanding.

     The holders of Series A Preferred Stock, if any, will be entitled to
receive (a) quarterly cumulative dividends payable in cash in an amount equal to
$1.00 per whole share, less the amount of cash dividends received pursuant to
the following clause (b) (but not less than zero) and (b) cash and in-kind
dividends on each payment date for similar dividends on the Common Stock in an
amount per whole share of Series A Preferred Stock equal to 100 (which number is
subject to adjustment to reflect stock dividends, subdivisions or combinations
of the outstanding Common Stock) times the per share amount of all cash
dividends then to be paid on each share of Common Stock.

     The holders of Series A Preferred Stock, if any, will be entitled to vote
on each matter on which holders of Common Stock are entitled to vote, and will
have 100 votes (subject to adjustment as described above) for each whole share
of Series A Preferred Stock held. Holders of any fraction of a share of Series A
Preferred Stock that is not smaller than one one-hundredth (1/100) of a share
will be entitled to vote such fraction. Holders of Series A Preferred Stock will
have certain special voting rights in the election of directors when the
equivalent of six quarterly dividends are in default.

     Whenever quarterly dividends or distributions on outstanding shares of
Series A Preferred Stock are in arrears, the Company's right to declare or pay
dividends or other distributions on, redeem or purchase any shares of stock
ranking junior to or on a parity with the Series A Preferred Stock will be
subject to certain restrictions.

     Upon any liquidation, dissolution or winding up of the Company, whether
voluntary or involuntary, the holders of Series A Preferred Stock will be
entitled to receive, before any distribution is made to holders of stock ranking
junior to the Series A Preferred Stock or any distribution (other than a ratable
distribution) is made to the holders of stock ranking on a parity with the
Series A Preferred Stock, an amount equal to the accrued dividends thereon plus
the greater of (a) $1.00 per share or (b) an amount per share equal to 100
(subject to adjustment as described above) times the amount per share to be
distributed to holders of Common Stock.

     The shares of Series A Preferred Stock will not be redeemable. However, the
Company may purchase shares of Series A Preferred Stock in the open market or
pursuant to an offer to any holder.

     In the event of a consolidation, merger or other transaction in which the
shares of Common Stock are exchanged for or converted into other securities,
cash or any other property, the shares of Series A Preferred Stock will be
similarly exchanged or converted.

     Shares of Series A Preferred Stock are issuable in whole shares or in any
fraction of a share that is not smaller than one one-hundredth (1/100) of a
share or any integral multiple of such fraction, subject to certain adjustments.
In lieu of issuing fractional shares, the Company may issue certificates or
depositary receipts evidencing such authorized fractions of shares or, in the
case of fractions other than one one-hundredth (1/100) of a share and integral
multiples thereof, pay registered holders cash equal to the same fraction of the
current market value of a share of Series A Preferred Stock (if any are
outstanding) or the equivalent number of shares of Common Stock. 

VOTING SHARE

     The Voting Share will be authorized for issuance in accordance with the 
Voting and Exchange Trust Agreement (the "Voting and Exchange Trust 
Agreement"), to be entered into between the Company, Subco, Promis and 
Montreal Trust Company of Canada (the "Trustee"). Except as otherwise 
required by law or the Company's Articles of Organization, the Voting Share 
will be issued by the Company to and deposited with the Trustee, to be held 
in trust for the benefit of the registered holders of Exchangeable Shares. 
The Voting Share will entitle the holder of record to a number of votes at 
meetings of holders of Common Stock equal to the product of (a) the number of 
Exchangeable Shares then issued and outstanding and held by registered 
holders of Exchangeable Shares other than the Company and its 

                                       21
<PAGE>


subsidiaries, multiplied by (b) the number of votes to which a
holder of one share of Common Stock is entitled with respect to any matter,
proposition or question on which holders of Common Stock are entitled to vote,
consent or otherwise act. Except as required by law or by the Company's Articles
of Organization, the holder of the Voting Share and the holders of Common Stock
will vote together as a single class in the election of directors and in all
matters submitted to a vote of the stockholders of the Company. The holder of
the Voting Share will not be entitled to receive dividends. In the event of any
dissolution, liquidation or winding up of the affairs of the Company, whether
voluntary or involuntary, the holder of the Voting Share will be entitled to be
paid out of the net assets of the Company available for distribution, before any
distribution or payment is made upon any stock of the Company ranking on
liquidation junior to the Special Voting Preferred Stock, an amount equal to
$1.00, subject to equitable adjustment in the event of stock splits, stock
dividends, combinations and the like involving the Special Voting Preferred
Stock. When the Voting Share has no votes attached to it because there are no
Exchangeable Shares outstanding not owned by the Company or any of its
subsidiaries, the Voting Share will be redeemed by the Company and be
automatically restored to the status of an authorized but unissued share of
Preferred Stock.

MASSACHUSETTS LAW AND CERTAIN PROVISIONS OF THE COMPANY'S AMENDED AND 
RESTATED ARTICLES OF ORGANIZATION AND THE COMPANY'S AMENDED AND RESTATED 
BY-LAWS

      The Company is subject to Chapter 110F of the Massachusetts General Laws,
an anti-takeover law. In general, Chapter 110F prohibits any Massachusetts
corporation with 200 or more stockholders of record and sufficient ties to
Massachusetts from engaging in a "business combination" with an "interested
stockholder" for a period of three years after the date on which the person
becomes an interested stockholder, unless (i) before that date, the board of
directors of the corporation approved either the business combination or the
transaction that resulted in the person becoming an interested stockholder, (ii)
upon consummation of the transaction that resulted in the person becoming an
interested stockholder, the interested stockholder owned at least 90% of the
voting stock outstanding at the time the transaction commenced (excluding shares
held by directors, officers and certain other affiliates of the corporation), or
(iii) on or after that date, the business combination is approved by the board
of directors and authorized at a meeting of stockholders (and not by written
consent) by the affirmative vote of two-thirds of the outstanding voting stock
that is not owned by the interested stockholder. In general, a "business
combination" includes any merger or consolidation involving the corporation or
any of its majority-owned subsidiaries, any sale, lease, exchange, mortgage,
pledge, transfer or other disposition of a specified percentage of the assets of
the corporation or any of its majority-owned subsidiaries, and certain other
transactions resulting in a financial benefit to the interested stockholder. In
general, an "interested stockholder" is a person that, individually or with or
through any of its affiliates or associates, beneficially owns 5% or more of the
voting stock of the corporation, or a person that is an affiliate or associate
of the corporation and beneficially owned 5% or more of the voting stock of the
corporation at any time within the previous three years, and the affiliates or
associates of that person. If the person is eligible to file Schedule 13G under
the rules of the Securities and Exchange Commission with respect to the
securities of the corporation, the applicable percentage is 15%. A corporation
subject to Chapter 110F may opt out of its coverage by action of its
stockholders to adopt an amendment to its articles of organization or by-laws
that, in addition to any other vote required by law, is approved by the
affirmative vote of a majority of the shares entitled to vote. Such an election
to opt out of the coverage of Chapter 110F will not be effective until twelve
months after the adoption of the foregoing amendment and will not apply to any
business combination between the corporation and any person that became an
interested stockholder before the adoption of the amendment. The Company has
more than 200 stockholders of record and has not elected to opt out of the
coverage of Chapter 110F.

     The Company is not subject to Chapter 110D of Massachusetts General Laws,
entitled "Regulation of Control Share Acquisitions." In general, this statute
provides that any stockholder of a corporation subject to this statute that
acquires beneficial ownership of 20% or more of the outstanding voting stock of
a corporation may not vote that stock unless the stockholders of the corporation
so authorize. (For purposes of the statute, a person is not deemed to be a
beneficial owner of shares as to which the person may exercise voting power
solely by virtue of 


                                       22
<PAGE>


a revocable proxy conferring the right to vote.) The Board of Directors may
amend the Company's By-Laws at any time to subject the Company to this statute
prospectively.

     The Company is not subject to Section 50A of the Massachusetts Business
Corporation Law, which generally requires that the board of directors of a
publicly held Massachusetts corporation be classified, with respect to the time
for which they severally hold office, into three classes as nearly equal in size
as possible. A corporation may opt out of the statute's coverage by a vote of
the board of directors or a vote of two-thirds of each class of stock
outstanding and entitled to vote at a meeting called for the purpose of such
vote. If a corporation opts out of the statute's coverage by vote of the board
of directors, the corporation may at any time thereafter adopt a vote of its
board of directors electing to be subject to the statute's coverage. Directors
who are classified under this statute may be removed only for cause by the
affirmative vote of a majority of the shares outstanding and entitled to vote in
the election of directors. The Company has elected by vote of its Board of
Directors to opt out of these classified board provisions.

     The Company's By-Laws provide that at a meeting of the stockholders called
for the purpose any director may be removed from office with or without cause by
the vote of a majority of the shares issued, outstanding and entitled to vote in
the election of directors. The Company By-Laws further provide that at any
meeting of the Board of Directors any director may, after reasonable notice and
an opportunity to be heard, be removed from office for cause by vote of a
majority of the directors then in office.

     The Company's By-Laws provide that any vacancy in the Board of Directors
may be filled by a vote of the majority of the directors then in office or, in
the absence of such election by the directors, by the stockholders at a meeting
called for the purpose, provided that, subject to the provisions of the
Company's By-Laws regarding nominations of directors, any vacancy resulting from
action by the stockholders may be filled by the stockholders at the same meeting
at which the action was taken. The Company's By-Laws require that stockholder
nominations for the Board of Directors comply with certain notice procedures. To
nominate a director, a stockholder must give the Company written notice of the
planned nomination at least 60 days before a scheduled meeting. If the Company
gives less than 70 days' notice of the date of the meeting, a stockholder will
have ten days within which to give such notice. The stockholder's notice of
nomination must include particular information about the stockholder, the
nominee and any beneficial owner on whose behalf the nomination is made. The
Company may require any proposed nominee to provide such additional information
as the Company may reasonably require to determine the eligibility of the
proposed nominee.

     The Company's By-Laws require that a stockholder seeking to have any
business conducted at a meeting of stockholders give written notice to the
Company at least 60 days before the scheduled meeting. In certain circumstances,
a stockholder will have ten days within which to give such notice. The
stockholder's notice must describe the proposed business to be brought before
the meeting and include information about the stockholder making the proposal,
any beneficial owner on whose behalf the proposal is made, and any other
stockholder known to support the proposal.

     The Massachusetts Business Corporation Law provides that special meetings
of stockholders of a corporation with a class of voting stock registered under
the Exchange Act may be called by the president or the directors of the
corporation, and unless otherwise provided in the corporation's charter or
by-laws, must be called by the clerk or another officer upon the written
application of the holders of at least 40% in interest of the corporation's
capital stock entitled to vote at a special meeting. The Company's By-Laws
mirror these provisions of the Massachusetts Business Corporation Law by
requiring the Company to call a special meeting of stockholders upon the written
application of the holders of at least 40% in interest of the Company's capital
stock entitled to vote at a special meeting.

     Article 6D of the Company's Articles of Organization expressly authorizes
the Board of Directors and the stockholders of the Company to make, alter, amend
and repeal the Company's By-Laws, except with respect to any 


                                       23
<PAGE>


provision which by law, the Company's Articles of Organization or the Company's
By-Laws require action by the stockholders. The Company's Articles of
Organization also provide that certain Articles of the Company's By-Laws
(relating generally to meetings of stockholders, meetings and elections of
directors, resignations, removals and vacancies of directors and officers, and
amendments to the Company's By-Laws) and Article 6D of the Company's Articles of
Organization may not be altered, amended or repealed by the stockholders, and no
provision inconsistent therewith may be adopted by them, without the affirmative
vote of the holders of at least eighty percent of the voting power of all shares
of the Company entitled to vote generally in the election of directors.

     The Company's Articles of Organization eliminate the personal liability of
the directors of the Company to the Company and its stockholders for monetary
damages for breach of fiduciary duty as a director to the maximum extent
permitted by the Massachusetts Business Corporation Law. The Company's Articles
of Organization generally provide that the Company will indemnify each person
who was or is made a party or is threatened to be made a party to or is
otherwise involved in any proceeding by reason of the fact that he or she is or
was a director or officer of the Company or serving at the Company's request as
a director, officer, employee or agent of another organization, including
service with respect to an employee benefit plan, to the fullest extent
authorized by the Massachusetts Business Corporation Law against all expense,
liability and loss reasonably incurred or suffered by such person in connection
therewith. The right to indemnification under the Company's Articles of
Organization includes the right to be paid by the Company the expenses incurred
in defending any proceeding in advance of its final disposition, subject to the
delivery of any undertaking required by the Massachusetts Business Corporation
Law. The Company's Articles of Organization grant the Board of Directors the
authority to grant rights to indemnification and advancement of expenses to any
employee or agent of the Company to the fullest extent permitted by the
Company's Articles of Organization.

     The Company's Articles of Organization provide that the Company may
authorize, by a vote of a majority of the shares of each class of stock
outstanding and entitled to vote thereon, (a) the sale, lease or exchange of all
or substantially all of its property and assets upon such terms and conditions
as it deems expedient, and (b) the merger or consolidation of the Company into
any other corporation, provided, however, that the sale, lease, exchange, merger
or consolidation is approved by a majority of the members of the Board of
Directors.

     Certain provisions of the Company's Articles of Organization and the
Company's By-Laws discussed above would make more difficult or discourage a
proxy contest or the assumption of control by a holder of a substantial block of
the Company's stock. These provisions could also have the effect of discouraging
a third party from making a tender offer or otherwise attempting to obtain
control of the Company, even though such an attempt might be beneficial to the
Company and its stockholders. In addition, because the Company's Articles of
Organization and the Company's By-Laws are designed to discourage accumulations
of large blocks of the Company's stock by purchasers whose objective is to have
such stock repurchased by the Company at a premium, these provisions could
reduce the temporary fluctuations in the market price of the Company's stock
that could otherwise be caused by such accumulations. Accordingly, the Company's
stockholders could be deprived of opportunities to sell their stock at
temporarily higher market prices.

TRANSFER AGENT AND REGISTRAR

     The transfer agent and registrar for the Common Stock is State Street Bank
and Trust Company.


                              PLAN OF DISTRIBUTION

     Holders of Exchangeable Shares should consult their own tax advisors with
respect to the United States, Canadian and other tax consequences of exchanging
their Exchangeable Shares for shares of Common Stock as 


                                       24
<PAGE>


described below. See "Risk Factors--Taxability of the Exchange." No broker,
dealer or underwriter has been engaged in connection with the offering of the
Common Stock covered hereby.

     The Company has filed with the SEC a Registration Statement on Form S-3, 
of which this Prospectus forms a part, with respect to the Common Stock being 
offered hereunder. The Company has agreed to use its reasonable best efforts 
to keep such Registration Statement effective until no Exchangeable Shares 
remain outstanding.

EXCHANGEABLE SHARES

     Pursuant to the terms of a plan of arrangement (the "Plan of Arrangement")
under section 192 of the Canada Business Corporations Act (the "CBCA"), Promis
will undergo a reorganization of capital (the "Arrangement") whereby, among
other things, Promis will issue Exchangeable Shares in exchange for outstanding
Promis Common Shares (other than Promis Common Shares held by PRI and its
subsidiaries) at the effective time (the "Effective Time") of the combination of
PRI and Promis. Each holder of Promis Common Shares will receive 0.1691
Exchangeable Shares for each Promis Common Share, such exchange ratio being
subject to adjustment as provided for in the Combination Agreement.

     Common Stock may be issued to holders of Exchangeable Shares as follows:
(i) holders of Exchangeable Shares may require at any time that such shares be
exchanged or redeemed for an equivalent number of shares of Common Stock (see
"--Election by Holders to Exchange or Redeem"); (ii) such Exchangeable Shares
will be automatically redeemed upon the occurrence of certain events (see
"--Automatic Redemption"); and (iii) upon liquidation of the Company or Promis,
holders of Exchangeable Shares may be required to, or may elect to, exchange
such Exchangeable Shares for shares of Common Stock (see "--Exchanges Upon
Liquidation of Promis or PRI").

     The Company will bear all of the expenses of this distribution. The Company
estimates that such expenses will total approximately $125,000.


ELECTION BY HOLDERS TO EXCHANGE OR REDEEM

     EXCHANGE PUT RIGHT. Holders of the Exchangeable Shares will be entitled 
at any time at or following the Effective Time to require Subco to purchase 
all or any part of the Exchangeable Shares owned by such holders and to 
deliver in exchange for such Exchangeable Shares an equivalent number of 
shares of Common Stock plus declared and unpaid and undeclared but payable 
dividends on each such Exchangeable Shares (the "Dividend Amount"), if any 
(the "Exchange Put Right"). The Exchange Put Right may be exercised at any 
time by notice in writing, which may be in the form of the exchange put right 
request contained in any letter of transmittal distributed or made available 
to Promis shareholders or in such other form satisfactory to the Trustee. 
Such notice must be given by the holder to and received by the Trustee, and 
accompanied by: (i) presentation and surrender of the certificates 
representing such Exchangeable Shares and (ii) such other documents that may 
be required to effect a transfer of Exchangeable Shares by the CBCA, Promis' 
by-laws and the Trustee. The required materials must be sent to the Trustee's 
principal transfer office in Toronto, Ontario or such other place in Canada 
as may be determined from time to time. An exchange pursuant to this right 
will be completed not later than the close of business on the third business 
day following receipt by the Trustee of the notice, the certificates and such 
other required documents.

     RETRACTION RIGHTS. Holders of the Exchangeable Shares will be entitled at
any time following the Effective Time to require Promis to retract (i.e.,
require Promis to redeem) any or all such Exchangeable Shares owned by such
holders and to deliver in exchange for such Exchangeable Shares an equivalent
number of shares of Common Stock plus the Dividend Amount, if any (the
"Retraction Price"), subject to Subco's Retraction Call Right as described
below. Holders of the Exchangeable Shares may effect such retraction by
presenting the appropriate share certificates to Promis or the Trustee
representing the number of Exchangeable Shares the holder desires Promis to
retract together with a duly executed retraction request (a "Retraction
Request") in the form contained 


                                       25
<PAGE>

in Schedule A to the rights, privileges, restrictions and conditions attaching
to the Exchangeable Shares set forth in Appendix A to the Plan of Arrangement
(the "Exchangeable Share Provisions") or in such other form as may be acceptable
to Promis specifying the number of Exchangeable Shares the holder wishes Promis
to retract and the retraction date upon which the holder wishes to receive the
Retraction Price (the "Retraction Date"). The Retraction Date will be a business
day not less than five nor more than ten business days after the date on which
Promis receives the Retraction Request from the holder, together with such other
documents as may be required to effect the retraction of the Exchangeable Shares
by the CBCA, Promis' by-laws and the Trustee.

     Upon receipt of the Exchangeable Shares, the Retraction Request and other
required documentation from the holder thereof, Promis must immediately notify
the Company and Subco of such Retraction Request. Subco will thereafter have two
business days in which to exercise its Retraction Call Right as discussed below
under "Call Rights" (the "Retraction Call Right"). In the event Subco determines
not to exercise its Retraction Call Right and provided that the Retraction
Request is not revoked by the holder in accordance with the Exchangeable Share
Provisions, Promis is obligated to deliver to the holder not later than the
Retraction Date the number of shares of Common Stock equal to the number of
Exchangeable Shares submitted by the holder for retraction, plus the Dividend
Amount, if any. The Company and Subco will be obligated to provide such shares
of Common Stock to Promis to enable Promis to comply with the Retraction
Request.

AUTOMATIC REDEMPTION

     Subject to applicable law and the Redemption Call Right of Subco described
below under "Call Rights" (the "Redemption Call Right"), on an Automatic
Redemption Date (defined below), Promis will redeem all but not less than all of
the then outstanding Exchangeable Shares in exchange for an equal number of
shares of Common Stock, plus the Dividend Amount, if any. An "Automatic
Redemption Date" is the first to occur of (a) the seventh anniversary of the
effective date (the "Effective Date") of the Arrangement, (b) the date selected
by the Promis board of directors at a time when less than 15% of the
Exchangeable Shares issuable on the Effective Date (other than shares held by
the Company and its subsidiaries and as such number of shares may be adjusted as
deemed appropriate by the Promis board of directors to give effect to any
subdivision or consolidation of or stock dividend on the Exchangeable Shares,
any issuance or distribution of rights to acquire Exchangeable Shares or
securities exchangeable for or convertible into or carrying rights to acquire
Exchangeable Shares, any issuance or distribution of other securities or rights
or evidences of indebtedness or assets, or any other capital reorganization or
other transaction involving or affecting the Exchangeable Shares) are
outstanding, (c) the business day prior to the record date for any meeting or
vote of the shareholders of Promis to consider any matter on which the holders
of Exchangeable Shares would be entitled to vote as shareholders of Promis, but
excluding any meeting or vote as described in clause (d) below (an "Exchangeable
Share Voting Event"), (d) the business day following the day on which the
holders of Exchangeable Shares fail to take the necessary action at a meeting or
other vote of the holders of Exchangeable Shares, if and to the extent such
action is required, to approve or disapprove, as applicable, any change to, or
in the rights of the holders of, Exchangeable Shares, if the approval or
disapproval, as applicable, of such change would be required to maintain the
economic and legal equivalence of the Exchangeable Shares and Common Stock (an
"Exchangeable Share Equivalence Voting Event"), or (e) a merger, amalgamation,
tender offer, material sale or capital distribution of shares or assets or
rights or interests therein or any similar transaction involving the Company, or
any proposal to do so (a "PRI Control Transaction") or a sale of a majority of
the outstanding shares of Promis by Subco, PRI or any affiliate of PRI to an
arm's length third party, or any proposal to do so (a "Promis Control
Transaction") occurs, in which case, provided the board of directors of Promis
determines, in good faith and in its sole discretion, that it is not reasonably
practicable in the circumstances of such PRI Control Transaction or Promis
Control Transaction to substantially replicate the terms and conditions of the
Exchangeable Shares in connection with such PRI Control Transaction or Promis
Control Transaction in accordance with its terms, the board of directors of
Promis may accelerate such redemption date to such date prior to the seventh
anniversary of the Effective Date as they may determine, upon such number of
days' prior written notice to the registered holders of the Exchangeable Shares
as the board of directors of Promis may determine to be reasonably practicable
in the circumstances.


                                       26
<PAGE>

     At least 45 days before the relevant Automatic Redemption Date, or such 
number of days as the board of directors of Promis may determine to be 
reasonably practicable under the circumstances in respect of a possible 
Automatic Redemption Date arising in connection with a PRI Control 
Transaction, a Promis Control Transaction, an Exchangeable Share Voting Event 
or an Exchangeable Share Equivalence Voting Event, Promis shall provide the 
registered holders of Exchangeable Shares with written notice of the proposed 
redemption of the Exchangeable Shares by Promis. In the case of any notice 
given in connection with a possible Automatic Redemption Date, such notice 
will be given contingently and will be withdrawn if the contingency does not 
occur.

EXCHANGES UPON LIQUIDATION OF PROMIS OR PRI

     PROMIS. Subject to Subco's Liquidation Call Right described below under
"Call Rights" (the "Liquidation Call Right"), in the event of the liquidation,
dissolution or winding up of Promis or any other distribution of its assets
among its shareholders for the purposes of winding up its affairs, a holder of
the Exchangeable Shares will have, subject to applicable law, preferential
rights to receive from Promis, for each Exchangeable Share, one share of Common
Stock, plus the Dividend Amount, if any.

     In addition, upon the occurrence and during the continuance of certain
events relating to Promis' insolvency described below (each, a "Promis
Insolvency Event"), a holder of Exchangeable Shares will be entitled to instruct
the Trustee to exercise the exchange right (the "Exchange Right") with respect
to any or all of the Exchangeable Shares held by such holder, thereby requiring
Subco to purchase such Exchangeable Shares from the holder. As soon as
practicable following the occurrence of a Promis Insolvency Event or any event
which may, with the passage of time and/or the giving of notice, become a Promis
Insolvency Event, Promis and Subco will give written notice thereof to the
Trustee. As soon as practicable thereafter, the Trustee will notify each holder
of Exchangeable Shares of such event or potential event and will advise the
holder of its rights with respect to the Exchange Right. The consideration for
each Exchangeable Share to be acquired under the Exchange Right will be one
share of Common Stock, plus the Dividend Amount, if any. "Promis Insolvency
Event" means the institution by Promis of any proceeding to be adjudicated a
bankrupt or insolvent or to be dissolved or wound-up, or the consent of Promis
to the institution of bankruptcy, insolvency, dissolution or winding-up
proceedings against it, or the filing of a petition, answer or consent seeking
dissolution or winding-up under any bankruptcy, insolvency or analogous laws,
including without limitation the Companies Creditors' Arrangement Act (Canada)
and the Bankruptcy and Insolvency Act (Canada), and the failure by Promis to
contest in good faith any such proceedings commenced in respect of Promis within
30 days of becoming aware thereof, or the consent by Promis to the filing of any
such petition or to the appointment of a receiver, or the making by Promis of a
general assignment for the benefit of creditors, or the admission in writing by
Promis of its inability to pay its debts generally as they become due. Moreover,
if as a result of liquidity or solvency requirements of applicable law, Promis
is unable to redeem all of the Exchangeable Shares tendered for retraction by a
holder in accordance with the Exchangeable Share Provisions as described under
"Retraction Rights" above, the holder will be deemed to have exercised the
Exchange Right with respect to the unredeemed Exchangeable Shares, and Subco
will be required to purchase such shares from the holder in the manner set forth
above.

     PRI. In order for holders of the Exchangeable Shares to participate on a
pro rata basis with the holders of Common Stock, immediately prior to the
effective time of a PRI Liquidation Event (as defined below), each Exchangeable
Share will be automatically exchanged for an equivalent number of shares of
Common Stock, plus the Dividend Amount, if any. Upon a holder's request and
surrender of Exchangeable Share certificates, duly endorsed in blank and
accompanied by such instruments of transfer as the Company or Subco, as
applicable, may reasonably require, the Company or Subco (if so determined by
the Company) will deliver to such holder certificates representing an equivalent
number of shares of Common Stock, plus the Dividend amount, if any. A "PRI
Liquidation Event" means: (a) any determination by the Board of Directors to
institute voluntary liquidation, dissolution or winding-up proceedings with
respect to the Company or to effect any other distribution of assets of the
Company among its stockholders for the purpose of winding-up its affairs, or (b)
the earlier of (i) receipt by the Company of notice of and (ii) the Company's
otherwise becoming aware of any threatened or instituted claim, 


                                       27
<PAGE>


suit, petition or other proceedings with respect to the involuntary liquidation,
dissolution or winding-up of the Company or to effect any other distribution of
assets of the Company among its stockholders for the purposes of winding up its
affairs, in each case where the Company has failed in good faith to contest in
good faith any such proceeding commenced in respect of the Company within 30
days of becoming aware thereof.

CALL RIGHTS

     In the circumstances described below, Subco will have certain overriding
rights (the "Call Rights") to acquire Exchangeable Shares from holders thereof
by delivering one share of Common Stock, plus the Dividend Amount, if any, for
each Exchangeable Share acquired.

     RETRACTION CALL RIGHT. Pursuant to the Exchangeable Share Provisions, a
holder requesting Promis to redeem the Exchangeable Shares will be deemed to
offer such shares to Subco, and Subco will have an overriding Retraction Call
Right to acquire all but not less than all of the Exchangeable Shares that the
holder has requested Promis to redeem in exchange for one share of Common Stock,
plus the Dividend Amount, if any, for each Exchangeable Share, and, upon the 
exercise by Subco of the Retraction Call Right, the holders of the 
Exchangeable Shares will be obligated to transfer such shares to Subco.

     LIQUIDATION CALL RIGHT. Pursuant to the Plan of Arrangement, Subco will
have an overriding Liquidation Call Right (the "Liquidation Call Right"), in the
event of and notwithstanding a proposed liquidation, dissolution or winding-up
of Promis or any other distribution of the assets of Promis among its
shareholders for the purpose of winding-up its affairs, to acquire all but not
less than all of the Exchangeable Shares then outstanding in exchange for one
share of Common Stock, plus the Dividend Amount, if any, for each Exchangeable
Share. Upon the exercise by Subco of the Liquidation Call Right, the holders of
Exchangeable Shares will be obligated to transfer such shares to Subco. The
acquisition by Subco of all of the outstanding Exchangeable Shares upon the
exercise of the Liquidation Call Right will occur on the effective date of the
voluntary or involuntary liquidation, dissolution or winding-up of Promis.

     REDEMPTION CALL RIGHT. Pursuant to the Plan of Arrangement, Subco will have
an overriding Redemption Call Right, notwithstanding the proposed automatic
redemption of the Exchangeable Shares by Promis pursuant to the Exchangeable
Share Provisions, to acquire on an Automatic Redemption Date all but not less
than all of the Exchangeable Shares then outstanding in exchange for one share
of Common Stock, plus the Dividend Amount, if any, for each Exchangeable Share,
and, upon the exercise by Subco of the Redemption Call Right, the holders of the
Exchangeable Shares will be obligated to transfer such shares to Subco.

     EFFECT OF CALL RIGHT EXERCISE. If Subco exercises one or more of its Call
Rights, it will directly deliver Common Stock to holders of Exchangeable Shares
and will become the holder of such Exchangeable Shares. Subco will not be
entitled to exercise any voting rights attached to the Exchangeable Shares it
acquires upon exercise of one or more of its Call Rights. If Subco declines to
exercise its Call Rights when applicable, the Company and Subco will be
required, pursuant to the Support Agreement to be entered between the Company,
Subco and Promis, to issue or deliver, as the case may be, Common Stock as
Promis directs, including to Promis, which will, in turn, transfer and/or
deliver such stock to the holders of Exchangeable Shares in consideration for
the return and cancellation of such Exchangeable Shares. the Company anticipates
that Subco will exercise its Call Rights, when available, and currently foresees
no circumstances under which Subco would not exercise its Call Rights. In
addition, the Company does not anticipate any restriction or limitation on the
number of Exchangeable Shares Subco would acquire upon exercise of its Call
Rights.

LSI WARRANT

     On May 1, 1996, Promis granted a warrant to purchase up to 100,000 
Promis Common Shares (the "LSI Warrant") to LSI Logic Corporation, a Delaware 
corporation ("LSI"). The LSI Warrant may be exercised at any time but not 
later than 5:00 p.m., Toronto time, on April 30, 2000. At the Effective Time, 
in accordance with the Plan of Arrangement, the LSI Warrant will be 
converted, without any further action on the part of LSI, into a warrant to 
purchase the number of shares of PRI Common Stock (the "Warrant Shares") 
equal to the product of the Exchange Ratio and the number of Promis Common 
Shares subject to issuance under the LSI Warrant (the "Replacement Warrant"). 
The Warrant Shares are included in the shares of Common Stock being offered 
hereunder. The Replacement Warrant will have an exercise price equal to the 
exercise price per share of the LSI Warrant immediately prior to the 
Effective Time divided by the Exchange Ratio and converted from Canadian 
dollars to United States dollars at the noon spot exchange rate announced by 
the Bank of Canada on the third business day immediately preceding the 
Effective Date. If the foregoing calculation results in the Replacement 
Warrant being exercisable for a fraction of a share of PRI Common Stock, then 
the number of shares of PRI Common Stock subject to the Replacement Warrant 
will be rounded down to the nearest whole number of shares and the total 
exercise price for the Replacement Warrant will be reduced by the exercise 
price of the fractional share of PRI Common Stock. All other terms of the LSI 
Warrant will remain unchanged upon the conversion into the Replacement 
Warrant.

                            INCOME TAX CONSIDERATIONS

CANADIAN FEDERAL INCOME TAX CONSIDERATION TO HOLDERS OF EXCHANGEABLE SHARES

     The Company has been advised by Blake, Cassels & Graydon, Canadian 
counsel for the Company, that the following is an accurate summary of the 
principal Canadian federal income tax considerations generally applicable to 
holders of Exchangeable Shares that, for purposes of the Income Tax Act 
(Canada) (the "Canadian Tax Act"), hold their Exchangeable Shares and the 
voting rights attached thereto, the Exchange Right and the Exchange Put Right 
(such rights being referred to collectively as the "Holder Rights") as 
capital property, deal at arm's length with Promis, the Company and Subco and 
are not affiliated with Promis, the Company or Subco. This summary does not 
apply to a holder with respect to whom the Company is or will be a foreign 
affiliate within the meaning of the Canadian Tax Act. This summary assumes 
that the Exchangeable Shares will at all times be listed on the TSE or 
another prescribed stock exchange. This summary does not address the tax 
consequences of the transactions, including the Arrangement, in which the 
Exchangeable Shares will be acquired, or the exercise of the LSI Warrant.

     Exchangeable Shares will generally be considered to be capital property 
to a holder unless held in the course of carrying on a business, in an 
adventure in the nature of trade or as "mark-to-market property" for purposes 
of the Canadian Tax Act. Shareholders resident in Canada for the purposes of 
the Canadian Tax Act whose Exchangeable Shares might not otherwise qualify as 
capital property may be entitled to obtain such qualification by making the 
irrevocable election provided by subsection 39(4) of the Canadian Tax Act. 
Shareholders who do not hold their shares as capital property should consult 
their own advisers regarding their particular circumstances and, in the case 
of certain "financial institutions" (as defined in Section 142.2 of the 
Canadian Tax Act), the potential application to them of the "mark-to-market" 
rules in the Canadian Tax Act, as the following summary does not apply to 
such shareholders.

     This summary is based on the current provisions of the Canadian Tax Act, 
the Regulations thereunder, the current provisions of the Canada-United 
States Income Tax Convention (1980), as amended ("Tax Treaty") and counsel's 
understanding of the current administrative practices of Revenue Canada, 
Customs, Excise and Taxation ("Revenue Canada"). This summary takes into 
account the amendments to the Canadian Tax Act and Regulations publicly 
announced by the Minister of Finance prior to the date hereof (the "Proposed 
Amendments") and assumes that all such Proposed Amendments will be enacted in 
their present form. However, no assurances can be given that the Proposed 
Amendments will be enacted in the form proposed, or at all.

     Except for the Proposed Amendments, this summary does not take into account
or anticipate any changes in law, whether by legislative, administrative or
judicial decision or action, nor does it take into account provincial,
territorial or foreign income tax legislation or considerations, which may
differ from the Canadian federal income tax considerations described herein. No
advance tax ruling has been sought or obtained from Revenue Canada to confirm
the tax consequences of any of the transactions described herein.

     WHILE THIS SUMMARY IS INTENDED TO ADDRESS THE PRINCIPAL CANADIAN FEDERAL 
INCOME TAX CONSIDERATIONS, IT IS OF A GENERAL NATURE ONLY AND IS NOT INTENDED 
TO BE, NOR SHOULD IT BE CONSTRUED TO BE, LEGAL, BUSINESS OR TAX ADVICE TO ANY 
PARTICULAR SHAREHOLDER. THEREFORE, SUCH HOLDERS AND PROSPECTIVE HOLDERS 
SHOULD CONSULT THEIR OWN TAX ADVISORS WITH RESPECT TO THEIR PARTICULAR 
CIRCUMSTANCES.

     For purposes of the Canadian Tax Act, all amounts must be expressed in
Canadian dollars, including dividends, adjusted cost base and proceeds of
disposition; amounts denominated in United States dollars must be converted into
Canadian dollars based on the prevailing United States dollar exchange rate
generally prevailing at the time such amounts arise.

SHAREHOLDERS RESIDENT IN CANADA

     The following portion of the summary is applicable to holders of
Exchangeable Shares ("Holders") who, for purposes of the Canadian Tax Act, are
resident or deemed to be resident in Canada ("Canadian Holders").


                                       29

DIVIDENDS

     EXCHANGEABLE SHARES. In the case of a Canadian Holder who is an 
individual, dividends received or deemed to be received on the Exchangeable 
Shares will be included in computing the Canadian Holder's income, and will 
generally be subject to the gross-up and dividend tax credit rules normally 
applicable to taxable dividends received from taxable Canadian corporations. 
In the case of a Canadian Holder that is a corporation, dividends received or 
deemed to be received on the Exchangeable Shares will be included in 
computing the Canadian Holder's income.

     Subject to the discussion set out below, in the case of a Canadian 
Holder that is a corporation, other than a "specified financial institution" 
as defined in the Canadian Tax Act, dividends received or deemed to be 
received on the Exchangeable Shares will be included in computing the 
corporation's income and will normally be deductible in computing its taxable 
income.

     In the case of a Canadian Holder that is a specified financial 
institution, a dividend which is otherwise deductible in accordance with the 
foregoing will be deductible in computing its taxable income only if either:

     (i)      the specified financial institution did not acquire the 
              Exchangeable Shares in the ordinary course of the business carried
              on by such institution; or

     (ii)     at the time of the receipt of the dividend by the specified
              financial institution, the Exchangeable Shares are listed on a
              prescribed stock exchange in Canada (which currently includes the
              TSE) and the specified financial institution, either alone or
              together with persons not dealing at arm's length with the
              Canadian Holder for purposes of the Canadian Tax Act does not 
              receive (and is not deemed to receive) dividends in respect of 
              more than 10 percent of the issued and outstanding Exchangeable
              Shares.

     A Canadian Holder that is a "private corporation" (as defined in the 
Canadian Tax Act) or any other corporation resident in Canada and controlled 
or deemed to be controlled by or for the benefit of an individual (other than 
a trust) or a related group of individuals (other than trusts) may be liable 
under Part IV of the Canadian Tax Act to pay a refundable tax of 33-1/3 
percent on dividends received or deemed to be received on the Exchangeable 
Shares to the extent that such dividends are deductible in computing the 
Canadian Holder's taxable income. A Canadian Holder that is a 
"Canadian-controlled private corporation" (as defined in the Canadian Tax 
Act) may be liable to pay an additional refundable tax of 6-2/3 percent on 
dividends or deemed dividends that are not deductible in computing taxable 
income.

     The Exchangeable Shares will be "taxable preferred shares" and 
"short-term preferred shares" and, subject to the discussion above, "term 
preferred shares" for purposes of the Canadian Tax Act. Accordingly, Promis 
will be subject to a 66-2/3 percent tax under Part VI. 1 of the Canadian Tax 
Act on dividends (other than excluded dividends) paid or deemed to be paid on 
the Exchangeable Shares. In certain circumstances, Promis may be entitled to 
deductions under Part I of the Canadian Tax Act which will substantially 
offset the impact of the Part VI. 1 tax. Dividends received or deemed to be 
received on the Exchangeable Shares by a Canadian Holder that is a 
corporation will not be subject to the 10 percent tax under Part IV. 1 of the 
Canadian Tax Act applicable to certain corporations.

     If the Company or any person with whom the Company does not deal at 
arm's length is a specified financial institution under the Canadian Tax Act 
at the time a dividend is paid on an Exchangeable Share, then, subject to the 
exemption described below, dividends received or deemed to be received by a 
Canadian Holder that is a corporation will not be deductible in computing 
taxable income but, as discussed above, will in any event be fully includable 
in computing income under Part I of the Canadian Tax Act. A corporation will 
generally be a specified financial institution for these purposes if it is a 
bank, a trust company, a credit union, an insurance corporation or a 
corporation whose principal business is the lending of money to persons with 
whom the corporation is dealing at arm's length or the purchasing of debt 
obligations issued by such persons or a combination thereof, or a corporation 
controlled by or related to any such entity or a prescribed corporation.

                                       30
<PAGE>

     The foregoing denial of the dividend deduction for a corporate Canadian 
Holder will not in any event apply if at the time a dividend is received or 
deemed to be received, the Exchangeable Shares are listed on a prescribed 
stock exchange (which currently includes the TSE), the Company controls 
Promis, and the recipient (together with persons with whom the recipient does 
not deal at arm's length or any partnership or trust of which the recipient 
or person is a member or beneficiary, respectively) does not receive 
dividends on more than 10 percent of the issued and outstanding Exchangeable 
Shares.

REDEMPTION OR EXCHANGE OF EXCHANGEABLE SHARES

     On the redemption (including a retraction) of an Exchangeable Share by 
Promis, the Canadian Holder will be deemed to have received a dividend equal 
to the amount, if any, by which the redemption proceeds (the fair market 
value at that time of the consideration received by the Canadian Holder as 
part of the exchange) exceeds the aggregate of the paid-up capital (for 
purposes of the Canadian Tax Act) at the time of the redemption of the 
Exchangeable Share, and any amount allocated to the cancellation of the 
Holder Rights attached to such shares. The amount of any such deemed dividend 
will generally be subject to the tax treatment described above under 
"Dividends -- Exchangeable Shares". On the redemption, the Canadian Holder 
will also be considered to have disposed of the Exchangeable Share for 
proceeds of disposition equal to the redemption proceeds less the amount of 
such deemed dividend and any amount allocated to the cancellation of the 
Holder Rights attached to such share and will also dispose of the Holder 
Rights attached to such share for proceeds of disposition equal to the amount 
allocated to the cancellation of the Holder Rights attached to such share. 
PRI is of the view that the fair market value of such rights is nominal. 
However, counsel can provide no opinion on matters of factual determination 
such as this. A Canadian Holder will in general realize a capital gain (or a 
capital loss) equal to the amount by which the adjusted cost base to the 
Canadian Holder is less than (or exceeds) the proceeds of disposition of the 
Exchangeable Share (net of reasonable costs of disposition) (see "Taxation of 
Capital Gain or Capital Loss" below). In the case of a Canadian Holder that 
is a corporation, in some circumstances the amount of any such deemed 
dividend may be treated as proceeds of disposition and not as a dividend 
pursuant to subsection 55(2) of the Canadian Tax Act.

     On the exchange of an Exchangeable Share by the Canadian Holder thereof 
with Subco for shares of Common Stock (including any related Rights), other 
than on the redemption or retraction of an Exchangeable Share, the Canadian 
Holder will in general realize a capital gain (or a capital loss) to the 
extent the proceeds of disposition of the Exchangeable Share, net of any 
reasonable costs of disposition, exceed (or are less than) the adjusted cost 
base to the Canadian Holder. For these purposes, the proceeds of disposition 
will be the aggregate fair market value, at the time of the exchange, of the 
consideration received by the Canadian Holder as part of the exchange (less 
any amount allocated to the cancellation of the Holder Rights attached 
thereto) (see "--Taxation of Capital Gain or Capital Loss" below).

     Because of the existence of the Call Rights and the Exchange Right, a 
Canadian Holder cannot control whether such Holder will receive shares of 
Common Stock by way of redemption of the Exchangeable Shares by Promis or by 
way of purchase of Exchangeable Shares by Subco, except to the extent that 
the Canadian Holder may exercise the Exchange Put Right. As described above, 
the Canadian federal income tax consequences of a redemption differ from 
those of an exchange.

TAXATION OF CAPITAL GAIN OR CAPITAL LOSS

     Three-quarters of any capital gain (the "taxable capital gain") realized 
by a Canadian Holder will be included in the Canadian Holder's income for the 
year of disposition. Three-quarters of any capital loss so realized (the 
"allowable capital loss") may be deducted by the Canadian Holder against 
taxable capital gains for the year of disposition. Any excess of allowable 
capital losses over taxable capital gains of the Canadian Holder for the year 
of disposition may be carried back up to three taxation years or forward 
indefinitely and deducted against net taxable capital gains in those other 
years to the extent and in the circumstances prescribed in the Canadian Tax 
Act.

     Capital gains realized by an individual or trust, other than certain 
trusts, may give rise to alternative minimum tax under the Canadian Tax Act. 
A Canadian Holder that is a Canadian-controlled private corporation may be 
liable to pay an additional refundable tax of 6-2/3 percent on taxable capital 
gains.

                                       31
<PAGE>


     If the Canadian Holder is a corporation, the amount of any capital loss 
arising on a disposition or deemed disposition of any such share may be 
reduced by the amount of dividends received or deemed to have been received 
by it on such share to the extent and under the circumstances prescribed by 
the Canadian Tax Act. Similar rules may apply where a corporation is a member 
of a partnership or a beneficiary of a trust that owns Exchangeable Shares or 
where a trust or partnership of which a corporation is a beneficiary or a 
member is a member of a partnership or a beneficiary of a trust that owns any 
such shares.

TAXATION OF PRI COMMON STOCK

     ACQUISITION AND DISPOSITION OF SHARES OF PRI COMMON STOCK. The cost 
amount of shares of PRI Common Stock received on the retraction, redemption 
or exchange of Exchangeable Shares will in general be equal to the fair 
market value of such shares of PRI Common Stock at the time of such event.

     A disposition or deemed disposition of shares of PRI Common Stock by a 
Canadian Holder will generally result in a capital gain (or capital loss) to 
the extent that the proceeds of disposition, net of any reasonable costs of 
disposition, exceed (or are less than) the adjusted cost base to the holder 
of shares of PRI Common Stock immediately before the disposition. In 
computing the adjusted cost base of a share of PRI Common Stock, the cost 
thereof must be averaged with the adjusted cost base of any other shares of 
PRI Common Stock held at that time by the Canadian Holder as capital property.

     DIVIDENDS ON SHARES OF PRI COMMON STOCK. Dividends received or deemed to 
be received by a Canadian Holder on shares of PRI Common Stock must be 
included in computing the income of the Canadian Holder for purposes of the 
Canadian Tax Act, and, in the case of a Canadian Holder that is an 
individual, such dividends will not be subject to the gross-up and dividend 
tax credit rules normally applicable to taxable dividends received from 
taxable Canadian corporations and, in the case of a Canadian Holder that is a 
corporation, such dividends will not be deductible in computing the 
corporation's taxable income for purposes of the Canadian Tax Act. Canadian 
Holders may in certain circumstances be entitled to a foreign tax credit in 
respect of any U.S. withholding tax payable in connection with such 
dividends, subject to the detailed rules in the Canadian Tax Act with respect 
to foreign tax credits, including in particular the proposed amendments to 
such rules set out in the Notice of Ways and Means Motion tabled in the House 
of Commons on December 10, 1998.

     FOREIGN PROPERTY INFORMATION REPORTING. A holder of shares of PRI Common 
Stock who is a "specified Canadian entity" for a taxation year or a fiscal 
period and whose total cost amounts of "specified foreign property," 
including such shares, at any time in the year or fiscal period exceeds Cdn. 
$100,000 will be required to file an information return for the year or 
period disclosing prescribed information, including the holder's cost amount, 
any dividends received in the year, and any gains or losses realized in the 
year, in respect of such property. With some exceptions, generally, a 
taxpayer resident in Canada in the year will be a specified Canadian entity. 
A holder of shares of PRI Common Stock should consult its own advisors about 
whether it must comply with these rules.

ELIGIBILITY FOR INVESTMENT IN CANADA

     QUALIFIED INVESTMENTS. The Exchangeable Shares if issued on the date
hereof, and the shares of Common Stock if issued on the date hereof, and listed
on a prescribed stock exchange (which currently includes the TSE and the
Nasdaq), would be qualified investments under the Canadian Tax Act for trusts
governed by registered retirement savings plans, registered retirement income
funds and deferred profit sharing plans. The Holder Rights attached to the 
Exchangeable Shares will generally not be qualified investments under the 
Canadian Tax Act. However, as indicated above, PRI is of the view that the 
fair market value of these rights is nominal.

     FOREIGN PROPERTY. Based in part on a certificate of an officer of 
Promis, the Exchangeable Shares if issued on the date hereof and listed on a 
prescribed stock exchange in Canada (which currently includes the TSE) would 
not be foreign property under the Canadian Tax Act for trusts governed by 
registered pension plans, registered retirement savings plans, registered 
retirement income funds and deferred profit sharing plans or for certain 
other tax-exempt persons. For the foregoing taxpayers, a penalty tax is 
imposed by Part XI of the Canadian Tax Act if the cost amount of their 
investment in the foreign property exceeds the statutory limit. The Holder 
Rights attached to the Exchangeable Shares will be foreign property under the 
Canadian Tax Act.

SHAREHOLDERS NOT RESIDENT IN CANADA

     The following portion of the summary is applicable to Holders who, for
purposes of the Canadian Tax Act, have not been and will not be resident or
deemed to be resident in Canada at any time while they held Promis Common Shares
or will hold Exchangeable Shares or shares of Common Stock and to whom such
shares are not taxable Canadian property and in the case of a non-resident of
Canada who carries on an insurance business in Canada and elsewhere, the shares
are not effectively connected with its Canadian insurance business and are not
designated insurance property ("Non-Canadian Holders").

     Exchangeable Shares will generally not be taxable Canadian property to a 
Non-Canadian Holder provided that such shares are listed on a prescribed 
stock exchange (which currently includes the TSE and Nasdaq), the 
Non-Canadian Holder does not use or hold, and is not deemed to use or hold, 
the Exchangeable Shares, in carrying on a business in Canada and the 
Non-Canadian Holder, persons with whom the Non-Canadian Holder does not deal 
at arm's length, or the Non-Canadian Holder and such persons, has not 

                                       32
<PAGE>


owned (or had rights to acquire) 25 percent or more of the issued shares of 
any class or series of the capital stock of Promis at any time within five 
years preceding the date of disposition, and has not acquired the 
Exchangeable Shares in a transaction where the Exchangeable Shares are deemed 
to be taxable Canadian property, such as where the Non-Canadian Holder 
disposed of taxable Canadian property and the resulting gain was deferred 
under the Canadian Tax Act.

     Even if an Exchangeable Share is considered to be taxable Canadian 
property, there may be relief available under an applicable tax convention, 
such as the Tax Treaty. Such Non-Canadian Holders should consult their own 
tax advisors to determine the tax consequences in their own situation.

     A Non-Canadian Holder will not in general be subject to any Canadian tax 
on a capital gain realized or deemed to have been realized on the disposition 
of an Exchangeable Share.

     When a Non-Canadian Holder exchanges the Exchangeable Shares for Common 
Stock, the Non-Canadian Holder may be deemed to have received a dividend 
subject to withholding tax (discussed below) and realized a capital gain or 
loss (generally tax-free as discussed above).

     Dividends paid on the Exchangeable Shares are subject to non-resident
withholding tax under the Canadian Tax Act at the rate of 25 percent of the
gross amount of the dividend, although such rate may be reduced under the
provisions of an applicable income tax treaty. For example, under the Tax
Treaty, the rate is generally reduced to 15 percent in respect of dividends paid
to a person who is the beneficial owner and who is resident in the United States
for purposes of the Tax Treaty.

     A Non-Canadian Holder whose Exchangeable Shares are redeemed (either 
under Promis's redemption right or pursuant to the Non-Canadian Holder's 
retraction rights) will be deemed to receive a dividend as and to the extent 
described above under the heading "Shareholders Resident in Canada", which 
deemed dividend will be subject to withholding tax as described in the 
preceding paragraph.

UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS TO HOLDERS OF EXCHANGEABLE 
SHARES

     The Company has been advised by Foley, Hoag & Eliot LLP that the 
following discussion is an accurate summary of the anticipated material 
United States federal income tax considerations generally applicable to 
holders of Exchangeable Shares under the United States Internal Revenue Code 
of 1986, as amended. This discussion does not address all the federal income 
tax considerations that may be relevant to particular holders of Exchangeable 
Shares in light of their particular circumstances, such as stockholders who 
are dealers in securities. In addition, the following discussion does not 
address the tax consequences of transactions, including the Arrangement, in 
which the Exchangeable Shares will be acquired, or the exercise of the LSI
Warrant. Furthermore, no foreign, state, or local tax considerations are 
addressed in this discussion.

     HOLDERS OF EXCHANGEABLE SHARES ARE URGED TO CONSULT THEIR OWN TAX ADVISORS
AS TO THE SPECIFIC TAX CONSIDERATIONS, INCLUDING THE FEDERAL, STATE, LOCAL, AND
FOREIGN TAX CONSIDERATIONS, APPLICABLE TO HOLDERS OF EXCHANGEABLE SHARES.

     The following discussion is based on the Code, applicable United States
Treasury regulations, judicial authority, and administrative rulings and
practice, all as of the date of this Registration Statement, and is for general
information only. No statutory, judicial, or administrative authority exists
that directly addresses certain of the United States federal income tax
consequences of the ownership of instruments and rights comparable to the
Exchangeable Shares, the voting rights attached thereto, the Exchange Put
Rights, and the Call Rights. 


                                       33

Consequently, some aspects of the United States federal income tax treatment of
the Arrangement, including the exchange of Exchangeable Shares for shares of
Common Stock, are not certain. No advance income tax ruling has been sought or
obtained from the United States Internal Revenue Service ("IRS") regarding the
tax consequences of any of the transactions described herein.

TAX CONSIDERATIONS APPLICABLE TO U.S. HOLDERS

     The following is a summary of the material United States federal income tax
considerations generally applicable to individual citizens or residents of the
United States for U.S. federal income tax purposes, corporations or partnerships
created in the United States or under the laws of the United States or of any
state, and estates or trusts other than foreign estates or trusts ("U.S.
Holders") who hold Exchangeable Shares as capital assets.

     EXCHANGE OF EXCHANGEABLE SHARES. It is anticipated that (subject to certain
exceptions described below) a U.S. Holder that exercises such holder's right to
exchange the Exchangeable Shares for shares of Common Stock (including an
exchange upon the occurrence of an Automatic Redemption Date) generally will
recognize gain or loss on the receipt of the shares of Common Stock in exchange
for such Exchangeable Shares. Such gain or loss will be equal to the difference
between the fair market value of the shares of Common Stock at the time of the
exchange and the U.S. Holder's tax basis in the Exchangeable Shares exchanged
therefor. The gain or loss will be capital gain or loss, except that, with
respect to any declared but unpaid dividends on the Exchangeable Shares,
ordinary income may be recognized by the holder thereof. Capital gain or loss
will be long-term capital gain or loss if the U.S. Holder's holding period in
the Exchangeable Shares is more than one year at the time of the exchange. The
U.S. Holder will take as such holder's tax basis in the shares of Common Stock
the fair market value of the shares of Common Stock received by the U.S. Holder
at the time of the exchange. The holding period of the shares of Common Stock
received by the U.S. Holder in the exchange will begin on the day after such
exchange.

     In view of the likelihood of the recognition of gain or loss upon the
exchange of Exchangeable Shares for shares of Common Stock, U.S. Holders may
wish to consider delaying such exchange until such time as they intend to
dispose of the shares of Common Stock receivable in exchange for their
Exchangeable Shares, until such time that Subco owns at least 80 percent of all
the then issued and outstanding Exchangeable Shares, or until Subco exercises
its Redemption Call Right or Liquidation Call Right.

     Under certain limited circumstances, the exchange by a U.S. Holder for
shares of Common Stock may be characterized as a tax-free exchange. First, an
exchange of Exchangeable Shares for shares of Common Stock may be characterized
as a tax-free exchange if, at the time of such exchange, (i) at least 80 percent
of the then outstanding Exchangeable Shares are held by Subco and (ii) in such
exchange, Subco, rather than Promis, acquires the Exchangeable Shares in
exchange for shares of Common Stock pursuant to the exercise of its Call Rights.
Second, an exchange of Exchangeable Shares for shares of Common Stock may be
characterized as a tax-free exchange if the U.S. Holder receives shares of
Common Stock from Subco upon the exercise by Subco of the Redemption Call Right
or the Liquidation Call Right. In either case, the exchange would not be
tax-free unless certain other requirements, which will depend upon the facts and
circumstances existing at the time of the exchange and cannot be accurately
predicted as of the date hereof, are satisfied.

     If such exchange did qualify as a tax-free exchange, a U.S. Holder would
recognize no gain or loss on an exchange of Exchangeable Shares for Common
Stock. An exchanging U.S. Holder would take as such holder's tax basis in the
shares of Common Stock such holder's tax basis in the Exchangeable Shares
exchanged therefor. The holding period of the shares of Common Stock received by
a U.S. Holder should include the holding period of the Exchangeable Shares
exchanged therefor, provided that such Promis Common Shares and Exchangeable
Shares have been held as capital assets immediately prior to the Arrangement and
the subsequent exchange, respectively. For United States federal income tax
purposes, gain realized on the exchange of Exchangeable Shares for shares of
Common Stock generally will be treated as United States source gain, except
that, under the 


                                       34
<PAGE>

terms of the Tax Treaty, such gain may be treated as sourced in Canada. Any
Canadian tax imposed on the exchange may be available as a credit against United
States federal income taxes, subject to applicable limitations. A U.S. Holder
that is ineligible for a foreign tax credit with respect to any Canadian tax
paid may be entitled to a deduction therefor in computing United States taxable
income.

     DISTRIBUTIONS ON THE EXCHANGEABLE SHARES. Although such treatment is not
free from doubt, the Company and Promis intend to treat distributions, if any,
with respect to the Exchangeable Shares as distributions from Promis, rather
than from the Company. Assuming such treatment is proper, a U.S. Holder
generally will be required to include in gross income, as ordinary income,
dividends paid on the Exchangeable Shares to the extent paid out of the earnings
and profits of Promis, as determined under United States federal income tax
principles. Such dividends generally will be treated as foreign source passive
income for foreign tax credit limitation purposes. Subject to certain
limitations of United States federal income tax law, a U.S. Holder should
generally be entitled to either a credit against such Holder's United States
federal income tax liability or a deduction in computing United States taxable
income for Canadian income taxes withheld from distributions with respect to the
Exchangeable Shares.

TAX CONSIDERATIONS APPLICABLE TO NON-U.S. HOLDERS

     The following summary is applicable to holders of Exchangeable Shares that 
are not U.S. Holders ("Non-U.S. Holders").

     EXCHANGE OF EXCHANGEABLE SHARES. A Non-U.S. Holder generally will not be
subject to United States federal income tax on gain (if any) recognized on the
sale or exchange of the Exchangeable Shares, or on the receipt or sale of shares
of Common Stock unless such gain is effectively connected with a United States
trade or business.

     DISTRIBUTIONS ON THE EXCHANGEABLE SHARES. Dividends received by a Non-U.S.
Holder with respect to the Exchangeable Shares should not be subject to United
States withholding tax. Therefore, Promis and the Company do not intend to
withhold any amounts in respect of such tax from such dividends. The IRS,
however, may assert that United States withholding tax is payable with respect
to dividends paid on the Exchangeable Shares to Non-U.S. Holders. As a result,
Non-U.S. Holders could be subject to United States withholding tax at a rate of
30 percent. The withholding rate may be reduced by an applicable treaty in
effect between the United States and the Non-U.S. Holder's country of residence.
Under the Tax Treaty, a maximum rate of 15 percent applies to dividends paid to
residents of Canada.

     DISTRIBUTIONS ON SHARES OF PRI COMMON STOCK. Dividends received by a 
Non-U.S. Holder with respect to the PRI Common Stock generally will be 
subject to United States withholding tax at a rate of 30 percent, which rate 
may be subject to reduction by an applicable income tax treaty (generally 15 
percent on dividends paid to residents of Canada under the Tax Treaty).

     GAIN ON SALE OR EXCHANGE OF PRI COMMON STOCK. A Non-U.S. Holder 
generally will not be subject to United States federal income tax on gain 
recognized on the sale or exchange of shares of PRI Common Stock unless such 
gain is effectively connected with a United States trade or business or, in 
the case of gain recognized by an individual, such individual is present in 
the United States for 183 days or more and certain other conditions are 
satisfied. (If PRI is at any time a "United States real property holding 
corporation" (a "USRPHC"), certain additional United States federal income 
tax rules, including withholding of United States tax on gross proceeds of 
the sale of shares of PRI Common Stock, may apply. PRI believes that it is 
not a USRPHC. Although PRI considers it unlikely that it will become a 
USRPHC, there can be no assurances as to this issue.)

Note to the unaudited financial statements

RECONCILIATION OF ACCOUNTING PRINCIPLES GENERALLY
ACCEPTED IN CANADA AND IN THE
UNITED STATES

The consolidated financial statements have been prepared in accordance with
accounting principles generally accepted in Canada ("Canadian GAAP") which, in
the case of the Company, conform in all material respects with those in the
United States ("US GAAP"), except as follows:

a)    The Company's revenue recognition policy under Canadian GAAP has been
      substantially in accordance with AICPA Statement of Position ("SOP") 91-1,
      "Software Revenue Recognition". Under US GAAP, for years ended after
      December 15, 1997, SOP 97-2, "Software Revenue Recognition", further
      codifies revenue recognition for software sales. Under SOP 97-2, a
      contract signed by both parties is the only acceptable evidence of an
      arrangement while Canadian GAAP and SOP 91-1 permitted other persuasive
      evidence of an arrangement. As a result, sales of $2,558 and expenses of
      $263 have not been recognized under US GAAP.

b)    Under US GAAP basic earnings per share are based on the weighted average
      number of common shares excluding contingent shares issued and shares
      issued pursuant to share purchase loans. Diluted earnings per share are
      calculated in accordance with the treasury stock method and are based on
      the weighted average number of common shares and dilutive common share
      equivalents outstanding.

c)    For reconciliation purposes to U.S. GAAP, the Company has applied the
      provisions of Statement of Financial Accounting Standards No. 109
      "Accounting for Income Taxes" (SFAS 109) effective August 31, 1993. Under
      SFAS 109, the liability method is used in accounting for income taxes.
      SFAS 109 requires recognition of deferred tax assets and liabilities for
      the expected future tax consequences of events that have been included in
      the financial statements or returns. Under this method, deferred tax
      assets and liabilities are determined based on the difference between the
      financial reporting and tax bases of assets and liabilities using enacted
      tax rates that will be in effect for the year in which the differences are
      expected to reverse. In addition this method provides for a valuation
      allowance against deferred tax assets where it is more likely than not
      that some portion or all of a deferred tax asset will not be realized.

      Under US GAAP, Research and Development investment tax credits would be
      credited to the income tax provision rather than as a net to research and
      development expenses. $300 was credited to research and development for
      the period ended September 30, 1998 under Canadian GAAP.

      The significant components of the Company's deferred tax assets, under US
      GAAP, are as follows:

d)    Under Canadian GAAP, unrealized foreign exchange gains and losses relating
      to non-current monetary items are deferred and amortized to income over
      the remaining life of the underlying non-current monetary item. Under US
      GAAP these unrealized foreign exchange gains and losses are recognized in
      income immediately. The amounts recognized each year for Canadian GAAP
      purposes, approximates the amounts which would have been recognized for US
      GAAP.

e)    Under US GAAP, gains and losses related to hedges of anticipated
      transactions may not be deferred unless a firm commitment exists while
      under Canadian GAAP, it is only necessary to have reasonable assurance
      that the anticipated transactions will occur. The liability at September
      30, 1998, measured at the current exchange rate, relating to future
      purchase contracts outstanding which are not hedges of firm commitments is
      approximately $300.

f)    Under Canadian GAAP, for purposes of the statements of cash flows, cash
      position includes all short-term investments less bank indebtedness. Under
      US GAAP, cash position includes highly liquid investments with original
      maturities of less than three months. Bank indebtedness is presented as a
      financing activity for purposes of US GAAP.

g)    Under Canadian GAAP, the forgiveness of a share purchase loan in 1997 was
      recognized as an increase of $454 to the Company's deficit. Under US GAAP,
      the share purchase loans are viewed as part of a variable compensation
      arrangement with changes in the value of the underlying shares recorded as
      adjustments to income in the year in which they occurred in periods prior
      to 1995. The resulting share purchase loan balance of $321 was charged to
      expense when the Company's Board of Directors approved the forgiveness in
      1995.

h)    Under Canadian GAAP, a reduction of the stated capital of outstanding
      common shares is allowed with a corresponding offset to deficit. This
      reclassification, which the Company made in 1997 to eliminate the deficit
      which existed at December 31, 1995, is not permitted by US GAAP and would
      result in an increase to share capital and corresponding decrease in
      retained earnings of $17,797.

i)    Under Canadian GAAP, stock options are accounted for at the date of
      exercise when the purchase is recorded as an increase to capital stock.
      For reconciliation purposes to US GAAP, the Company has chosen to follow
      APB 25 in accounting for stock options granted to directors, officers and
      employees. Since the exercise price of the Company's employee stock
      options equals the market price of the underlying stock on the date of the
      grant no compensation expense has been recognized.

j)    The Financial Accounting Standards Board has issued Statement of Financial
      Accounting Standards No. 130 "Comprehensive Income" ("SFAS 130"). SFAS 130
      requires companies to report comprehensive income which includes all
      changes in stockholders' equity during a period except those resulting
      from investments by owners and distributions to owners. For purposes of
      reconciliation to US GAAP, the Company's comprehensive income would equal
      its net income for the periods presented.

                                AUDITORS' REPORT

To the Directors of
Promis Systems Corporation Ltd.

We have audited the consolidated balance sheets of Promis Systems Corporation
Ltd. as at December 31, 1997 and 1996 and the consolidated statements of income
(loss) and retained earnings (deficit) and changes in financial position for
each of the years in the three-year period ended December 31, 1997. 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 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 December 31, 1997
and 1996 and the results of its operations and the changes in its financial
position for each of the years in the three-year period ended December 31, 1997
in accordance with generally accepted accounting principles.

Promis Systems Corporation Ltd.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
    [U.S. dollars, tabular amounts in thousands except per share information]

1. SIGNIFICANT ACCOUNTING POLICIES

These consolidated financial statements have been prepared by management in
accordance with accounting principles generally accepted in Canada. The more
significant accounting policies are as follows:

Basis of consolidation

These consolidated financial statements include the accounts of Promis Systems
Corporation Ltd. [the "Company"] and its wholly-owned subsidiaries: Promis
Systems Corporation, incorporated under the laws of Delaware, United States of
America; Promis Systems Corporation (U.K.) Limited, incorporated under the laws
of England and Wales; Promis Systems Corporation Limited, incorporated under the
laws of Hong Kong; MSISUB Inc., incorporated under the laws of Delaware, United
States of America; Promis Systems Corporation Singapore Pte Ltd., incorporated
under the laws of Singapore; and Promis Systems Corporation GmbH, incorporated
under the laws of the Federal Republic of Germany. These consolidated financial
statements are expressed in United States dollars, the operating currency of the
Company.

Capital assets

Capital assets are recorded at cost less accumulated amortization. Amortization
is provided using the following annual rates and bases which are expected to
amortize the cost of the capital assets over their estimated useful lives:

Computers, software and communications
  equipment                               33 1/3% declining balance
Furniture and equipment                   20% declining balance
Leasehold improvements                    straight-line over the lease term

Intellectual property, which represents the value of software rights purchased,
is amortized to income on a straight-line basis over three years.

Investment tax credits

Investment tax credits are accrued when qualifying expenditures are made and
there is reasonable assurance that the credits will be realized. The Company
accounts for investment tax credits using the cost reduction method.



                                      F-13
<PAGE>

Income taxes

The Company follows the deferral method of income tax allocation. Deferred
income taxes result from claiming deductions for income tax purposes in amounts
which differ from those charged in the accounts.

Research and development expenditures

Research costs are expensed in the year incurred. Development costs are expensed
in the year incurred unless a development project meets the criteria under
generally accepted accounting principles for deferral and amortization. One of
the criteria of generally accepted accounting principles requires that
development costs should be deferred when the product is considered to be
technically feasible. The Company considers technical feasibility to be
established when the product reaches the "BETA Release" stage in development.
Capitalized development costs are amortized to income on a straight-line basis
over the estimated life of the product, commencing with the market introduction
of the related product. The average period of amortization is three years. These
expenditures are also reduced by related investment tax credits.

Goodwill

Goodwill represents the excess of the purchase price over the fair value of net
assets acquired and is amortized to income on a straight-line basis over 20
years. Goodwill is written down to reflect any other than temporary impairment
in ongoing value which is believed to have occurred. The Company assesses
whether permanent impairment in value has occurred based on its estimate of the
fair value of the related business operations.

Revenue recognition

Revenue from software sales is recognized on delivery of the software and an
irrevocable commitment to purchase made by the customer.

Revenue from software service agreements and other contracts is recognized on a
straight-line basis over the term of the contract.

Revenue from consulting and training services is recognized when the services
are performed.

Unearned revenue arises when billings are made in advance of revenue
recognition.

Financial instruments

The fair values of financial instruments approximate their carrying values
except as otherwise disclosed in these consolidated financial statements.

Foreign currency translation

The Company's subsidiaries are considered to be integrated operations.
Accordingly, monetary assets and liabilities denominated in foreign currencies
are translated into United States dollars at the rate of exchange prevailing at
the year end while other consolidated balance sheet items are translated at
historic rates. Revenue and expenses are translated at the rate of exchange in
effect on the transaction dates. Realized and unrealized foreign exchange gains
and losses are included in income in the year in which they occur, except where
they arise from translation of non-current monetary items. Such gains and losses
are deferred and amortized to income on a straight-line basis over the remaining
life of the underlying non-current monetary items.

Short-term deposits

Short-term deposits include such items as short-term guaranteed investment
certificates are carried at cost which approximates market value and mature in
January 1998.

Capital leases

A lease which transfers substantially all of the benefits and risks incidental
to the ownership of property is accounted for as if it were an acquisition of an
asset and the incurrence of an obligation at the inception of the lease. Assets
recorded under capital leases are amortized over the initial non-cancellable
term of the lease on a basis consistent with accounting for capital assets.

2. CAPITAL ASSETS

6. DEFERRED TENANT INDUCEMENT

The deferred tenant inducement relates to the 10-year lease of the Company's
Toronto office premises effective January 1, 1997. Generally accepted accounting
principles require that the total lease payments over the lease term be
aggregated and charged as rent expense evenly over the term of the lease. The
cumulative difference between the rent expense charged to income and the lease
payments made is recorded as a deferred tenant inducement on the consolidated
balance sheets.

Forgiveness of share purchase loan

As at December 31, 1995, a share purchase loan of approximately $530 thousand
[Cdn.$567 thousand] was outstanding. During 1996, approximately $76 thousand
[Cdn.$131 thousand) of the loan was settled by surrender of 27,821 shares held.

share purchase loan of $454 thousand effective January 1, 1997. The forgiveness
of the loan did not require the surrender of shares held and accordingly, the
amount of the loan has been charged to retained earnings.

The Company has scientific research deductions available for carryforward to
apply against taxable income in future years of approximately $11.9 million
federally and $12.3 million provincially.

As the Company is a public company for Canadian tax purposes, it is eligible for
investment tax credits of 20% on its qualifying current and capital research and
development expenditures incurred in each year. These credits are available to
reduce up to 100% of Canadian federal income taxes payable. The potential income
tax benefits of investment tax credits with respect to expenditures made in 1997
have not been recorded in the accounts.

Research and development expenditures incurred in the year have been reduced by
$1.5 million of previously unrecognized investment tax credits that were earned
in previous years [1996 - nil, 1995 - nil].

In addition, the Company has investment tax credits available of approximately
$2.0 million as at December 31, 1997 to reduce future years' income taxes. The
benefit of these investment tax credits has not been reflected in the
consolidated financial statements. These investment tax credits will begin to
expire in 2005.

9. GOODWILL AND INTELLECTUAL PROPERTY WRITE-OFFS

During 1995, the Company decided to restructure and focus on its strengths and
capabilities in the semi-conductor market. Accordingly, the Palette business was
discontinued. As a result, a permanent impairment of goodwill and intellectual
property occurred. The following amounts related to Pallette goodwill and
intellectual property were written off during 1995:

The Company also made a strategic decision to sell the MADEMA software
exclusively as a module integrated with the PROMIS software, in order to enhance
the marketability of the PROMIS product suite.

It is anticipated that the incremental development and maintenance costs to
integrate the MADEMA software to PROMIS will not be recovered through future
sales of MADEMA. Based upon this decision and the resulting estimated net
recoverable amount, the intellectual property value of MADEMA has been
permanently impaired. Accordingly, the intellectual property value of MADEMA in
the amount of $292 thousand was written off in 1995.

10. PROVISION FOR RESTRUCTURING CHARGES

During the third quarter of 1995, the Company implemented a formal restructuring
plan to focus on its strengths and capabilities in the semiconductor market. As
part of the plan, the Company reduced its work force and closed certain offices.
A provision for exit costs from these operations including the Palette business
[note 9] was accrued. The provision includes special termination benefits of
$1.0 million and costs of leased property no longer of use to the Company of
$280 thousand. Approximately $500 thousand of the termination benefit has been
collateralized by an assignment of book debts of the Company, subordinate to the
operating line of credit. As at December 31, 1997, $1.55 million [December 31,
1996, $1.1 million] of the exit costs accrued have been paid. It is anticipated
that the remaining balance of the accrual will be paid in 1999.

14. CONTINGENT LIABILITY

In 1993, the Company purchased the business assets and assumed selected
liabilities of Palette Systems Inc. The purchase price of approximately $9.9
million consisted of approximately $5.5 million in cash and 442,638 common
shares of the Company, valued at $10 per common share. At that time the Company
agreed that on April 7, 1998 it would pay additional cash consideration to the
vendors of an amount equal to the amount by which approximately $4 million
exceeded market value of the common shares owned by the vendors on April 7,
1998.

On March 29, 1996, the Company made a formal claim against the vendors pursuant
to the dispute resolution provisions of the original purchase and sale
agreements and the vendors filed certain counterclaims against the Company.

In 1997, the Company and the vendors reached a settlement of the dispute. The
settlement provides that commencing on April 7, 1998 the Company would pay
additional cash to the vendors of an amount equal to the amount by which 442,638
common shares are less than the market value, on each of the payment dates
described hereunder, of $10 per common share. As part of the settlement, the
additional cash consideration, if any, will be payable as to 50% on April 7,
1998 and the balance as to 2.5% on a quarterly basis commencing on July 7, 1998,
up to and including April 7, 2003. Under the terms of the settlement agreement,
the vendors are restricted as to the number of shares which can be sold in any
given quarter to April 7, 2003.

Since the payment of additional consideration is dependent on the Company's
share price at various future dates, any additional consideration will be
recorded as a reduction in share capital of the Company as the amounts become
determinable.

The Company's contingent liability calculated based on the market value of the
common shares at February 27, 1998, is approximately $1.4 million.

15. COMPARATIVE CONSOLIDATED FINANCIAL STATEMENTS

The comparative consolidated financial statements have been reclassified from
statements previously presented to conform to the presentation of the 1997
consolidated financial statements.

16. RECONCILIATION OF ACCOUNTING PRINCIPLES GENERALLY ACCEPTED IN CANADA AND IN
    THE UNITED STATES

The consolidated financial statements have been prepared in accordance with
accounting principles generally accepted in Canada ["Canadian GAAP"] which, in
the case of the Company, conform in all material respects with those in the
United States ["US GAAP"], except as follows:

[a]   Under US GAAP basic earnings per share are based on the weighted average
      number of common shares excluding contingent shares issued and shares
      issued pursuant to share purchase loans. Diluted earnings per share are
      calculated in accordance with the treasury stock method and are based on
      the weighted average number of common shares and dilutive common share
      equivalents outstanding.

[b]   For reconciliation purposes to U.S. GAAP, the Company has applied the
      provisions of Statement of Financial Accounting Standards No. 109
      "Accounting for Income Taxes" [SFAS 109] effective August 31, 1993. Under
      SFAS 109, the liability method is used in accounting for income taxes.
      SFAS 109 requires recognition of deferred tax assets and liabilities for
      the expected future tax consequences of events that have been included in
      the financial statements or returns. Under this method, deferred tax
      assets and liabilities are determined based on the difference between the
      financial reporting and tax bases of assets and liabilities using enacted



                                      F-22
<PAGE>

      tax rates that will be in effect for the year in which the differences are
      expected to reverse. In addition this method provides for a valuation
      allowance against deferred tax assets where it is more likely than not
      that some portion or all of a deferred tax asset will not be realized.

      Under US GAAP, Research and Development investment tax credits would be
      credited to the income tax provision rather than as a net to research and
      development expenses. The amounts credited to research and development
      expenses were $1,500 in 1997, nil in 1996 and nil in 1995.

      The significant components of the Company's deferred tax assets, under US
      GAAP, as at December 31, 1997, 1996 and 1995 are as follows:

</TABLE>

[c]   Under Canadian GAAP, unrealized foreign exchange gains and losses relating
      to non-current monetary items are deferred and amortized to income over
      the remaining life of the underlying non-current monetary item. Under US
      GAAP these unrealized foreign exchange gains and losses are recognized in
      income immediately. The amounts recognized each year for Canadian GAAP
      purposes approximates the amounts which would have been recognized for US
      GAAP.

[d]   Under Canadian GAAP, for purposes of the statements of cash flows, cash
      position includes all short-term investments less bank indebtedness. Under
      US GAAP, cash position includes highly liquid investments with original
      maturities of less than three months. Bank indebtedness is presented as a
      financing activity for purposes of US GAAP.

[e]   Under Canadian GAAP, the forgiveness of a share purchase loan in 1997 was
      recognized as an increase of $454 to the Company's deficit. Under US GAAP,
      the share purchase loans are viewed as part of a variable compensation
      arrangement with changes in the value of the underlying shares recorded as
      adjustments to income in the year in which they occurred in periods prior
      to 1995. The resulting share purchase loan balance of $321 was charged to
      expense when the Company's Board of Directors approved the forgiveness in
      1995.

[f]   Under Canadian GAAP, a reduction of the stated capital of outstanding
      common shares is allowed with a corresponding offset to deficit. This
      reclassification, which the Company made in 1997 to eliminate the deficit
      which existed at December 31, 1995, is not permitted by US GAAP and would
      result in an increase to share capital and corresponding decrease in the
      retained earnings of $17,797.

[g]   Under Canadian GAAP, stock options are accounted for at the date of
      exercise when the purchase is recorded as an increase to capital stock.
      For reconciliation purposes to US GAAP, the Company has chosen to follow
      APB 25 in accounting for stock options granted to directors, officers and
      employees. Since the exercise price of the Company's employee stock
      options equals the market price of the underlying stock on the date of the
      grant, no compensation expense has been recognized.

[h]   The Financial Accounting Standards Board has issued Statement of Financial
      Accounting Standards No. 130 "Comprehensive Income" ['SFAS 130']. SFAS 130
      requires companies to report comprehensive income which includes all
      changes in stockholders' equity during a period except those resulting
      from investments by owners and distributions to owners. For purposes of
      reconciliation to US GAAP, the Company's comprehensive income would equal
      its net income for the periods presented.

The following table reconciles the net income as reported on the consolidated
statements of earnings (loss) to that which would have been reported had the
financial statements been prepared in accordance with US GAAP and the

                              FINANCIAL STATEMENTS

      The unaudited pro forma condensed combined statements of operations 
combine PRI's audited consolidated results of operations for each of the two 
years in the period ended September 30, 1998 with Promis' unaudited 
consolidated results of operations for the twelve-month period ended 
September 30, 1998 and audited consolidated results of operations for the 
year ended December 31, 1997, respectively, giving effect to the Transaction 
as if it had occurred at the beginning of each period presented on a 
pooling-of-interests basis. The unaudited pro forma condensed combined 
balance sheet data combines PRI's audited consolidated balance sheet data as 
of September 30, 1998 with Promis' unaudited consolidated balance sheet data 
as of that date, giving effect to the Transaction as if it had occurred on 
September 30, 1998. The historical financial information of PRI has been 
derived from its audited consolidated financial statements for each of the 
two years in the period ended September 30, 1998, which have been 
incorporated by reference. The historical financial information of Promis has 
been derived from its accounting records for the twelve-month period ended 
September 30, 1998 and its audited consolidated financial statements for the 
year ended December 31, 1997 on the basis of U.S. GAAP and should be read in 
conjunction with the unaudited interim consolidated financial statements for 
the nine-month period ended September 30, 1998 and the audited financial 
statements for the year ended December 31, 1997 and the notes thereto, which 
have been included herein. In the opinion of the management of Promis, the 
above-mentioned unaudited interim financial data of Promis includes all 
adjustments, consisting only of normal recurring adjustments, necessary for a 
fair presentation of the results for the unaudited twelve-month interim 
period that combines the nine-month period ended September 30, 1998 and the 
three-month period ended December 31, 1997. The pro forma information is 
presented for illustrative purposes only and is not necessarily indicative of 
the consolidated results of operations or financial position that would have 
occurred had the Transaction been consummated at the beginning of the periods 
presented, nor is it necessarily indicative of future results of operations 
or financial position.

(1)   The historical Promis statement of operations data have been calculated
      using date for the twelve-month period ended September 30, 1998 and have
      been prepared in accordance with U.S. GAAP.

(2)   The number of shares used in the historical Promis per common share
      computation was derived from Promis' dilutive outstanding shares and share
      equivalents as of September 30, 1998. The number of shares used for the
      Pro Forma combined diluted net loss per common share was derived from
      Promis' basic outstanding shares as of September 30, 1998, multiplied by
      the assumed exchange ratio of 0.1691, plus PRI's historical basic shares
      outstanding as of September 30, 1998. Under U.S. GAAP, the computation of
      diluted net (loss) income per common share does not assume the issuance of
      common shares that have an anti-dilutive effect.

                 NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED
                              FINANCIAL STATEMENTS

1.    Certain financial statement balances of Promis have been reclassified to
      conform with PRI financial statement presentation.

2.    The adjustments to the unaudited pro forma condensed combined balance
      sheet give effect to the issuance of 1,725,660 shares of PRI Common Stock
      based on an assumed exchange ratio of 0.1691 as if the Transaction had
      been consummated as of September 30, 1998 and an anticipated charge for
      Transaction-related expenses totaling approximately $5.5 million, less
      anticipated income tax benefits. Such expenses include investment advisory
      fees, legal and accounting expenses and other transaction costs ($2.8
      million), other direct costs associated with the Transaction ($0.8
      million) and incremental operating costs associated with anticipated
      employee termination benefits and elimination of redundant facilities
      ($1.9 million). The unaudited pro forma condensed combined statements of
      operations do not reflect these non-recurring charges, which PRI
      anticipates will be recorded during the twelve-month period following
      consummation of the Transaction.

3.    The unaudited pro forma condensed combined financial statements do not
      include all adjustments to conform the accounting policies of Promis to
      those followed by PRI. The nature and extent of adjustments in addition to
      those discussed herein, if any, will be based upon further study and
      analysis and are not expected to be significant in relationship to the
      consolidated financial statements of PRI. The unaudited pro forma
      condensed combined statements of operations data include certain
      adjustments to Promis' accounting policies to conform them with PRI's
      accounting policies on revenue recognition. The unaudited pro forma
      condensed combined balance sheet includes an adjustment for an anticipated
      charge for Transaction-related expenses described in Note 2.

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Article 6C of the Company's Restated Articles of Organization provides that
the Company (with certain exceptions) will indemnify and hold harmless to the
fullest extent authorized by the Massachusetts Business Corporation Law each
person who was or is made a party or is threatened to be made a party to or is
otherwise involved in any action, suit or proceeding, whether civil, criminal,
administrative, investigative or otherwise (hereinafter a "Proceeding"), by
reason of the fact that he or she is or was (a) a director of the Company, (b)
an officer of the Company elected or appointed by the stockholders or the Board
of Directors, or (c) serving, at the request of the Company as evidenced by a
vote of the Board of Directors prior to the occurrence of the event to which the
indemnification relates, as a director, officer, employee or other agent of
another corporation or of a partnership, joint venture, trust or other
enterprise, including service with respect to an employee benefit plan (such
persons described in (a), (b) and (c) are sometimes hereinafter referred to as
an "Indemnitee") against all expense, liability, and loss reasonably incurred by
any such Indemnitee in connection therewith. The Company may also, to the extent
authorized by the Board of Directors, grant rights to indemnification, and to an
advancement of expenses, to any employee or agent of the Company.
Notwithstanding the foregoing, if Massachusetts Business Corporation Law
requires, an advancement of expenses incurred by an Indemnitee will be made only
upon delivery to the Company of an undertaking, by or on behalf of such
Indemnitee, to repay all amounts so advanced if it shall ultimately be
determined by final judicial decision from which there is not further right to
appeal that such Indemnitee is not entitled to be indemnified for such expenses.

     The rights under Article 6C may not be amended or terminated so as to
adversely affect an individual's rights with respect to the period prior to such
amendment without the consent of the person entitled to the indemnification
(unless otherwise required by the Massachusetts Business Corporation Law).

     Section 67 of Chapter 156B of the Massachusetts Business Corporation Law
authorizes a corporation to indemnify its directors, officers, employees and
other agents unless such person shall have been adjudicated in any proceeding
not to have acted in good faith in the reasonable belief that his action was in
the best interests of the Corporation or to the extent that such matter relates
to service with respect to an employee benefit plan, in the best interests of
the participants of such employee benefit plan.

     The effect of these provisions would be to authorize such indemnification
by the Company for liabilities arising out of the Securities Act of 1933.

ITEM 17.      UNDERTAKINGS

      (a)   The undersigned registrant hereby undertakes:

            (1)   To file, during any period in which offers or sales are being 
made, a post-effective amendment to this Registration Statement:

                  (i)  To include any prospectus required by Section 10(a)(3) of
the Securities Act of 1933;

                  (ii) To reflect in the prospectus any facts or events arising
after the effective date of the Registration Statement (or the most recent
post-effective amendment thereof) which, individually or in the aggregate,
represent a fundamental change in the information set forth in the Registration
Statement. Notwithstanding the foregoing, any increase or decrease in the volume
of securities offered (if the total dollar value of securities offered would not
exceed that which was registered) and any deviation from the low or high end of
the estimated maximum offering range may be reflected in the form of a
prospectus filed with the Commission pursuant to Rule 424(b) if, in the
aggregate, the changes in volume and price represent no more than a 20 percent
change in the maximum aggregate offering price set forth in the "Calculation of
Registration Fee" table in the effective Registration Statement;

                  (iii) To include any material information with respect to the
plan of distribution not previously disclosed in the Registration Statement or
any material change to such information in the Registration Statement;

PROVIDED, HOWEVER, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the
information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed with or furnished to the
Commission by the registrant pursuant to Section 13 or 15(d) of the Securities
Exchange Act of 1934 that are incorporated by reference in this Registration
Statement.

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

            (3) To remove from registration, by means of a post-effective
amendment, any of the securities being registered which remain unsold at the
termination of the offering.

      (b) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 (and, where applicable, each filing of an employee benefit
plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of
1934) that is incorporated by reference in the Registration Statement shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial BONA FIDE offering thereof.


                                       II-3
<PAGE>


      (c) Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the registrant pursuant to the foregoing provisions, or otherwise,
the registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the 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 defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.

    2.1.  PLAN OF ARRANGEMENT.
 
        2.1.1.  As promptly as practicable, the Company shall apply to the Court
    pursuant to Section 192 of the CBCA for an interim order in form and
    substance reasonably satisfactory to Parent (the "Interim Order") providing
    for, among other things, the calling and holding of a special meeting of the
    shareholders of the Company (the "Company Shareholder Meeting") for the
    purpose of considering and, if deemed advisable, approving the arrangement
    (the "Arrangement") under Section 192 of the CBCA and pursuant to this
    Agreement and the Plan of Arrangement substantially in the form of EXHIBIT
    A, with such changes, modifications and additions thereto as the parties may
    reasonably agree upon (the "Plan of Arrangement"). The notice of motion for
    the application for the Interim Order shall request that the Interim Order
    provide (a) for the class of Persons to whom notice shall be provided in
    respect of the Arrangement and the Company Shareholder Meeting and for the
    manner in which such notice shall be provided, (b) that the requisite
    shareholder approval for the special resolution approving the Arrangement
    shall be 66 2/3% of the votes cast on such special resolution by holders of
    Company Common Shares present in person or by proxy at the Company
    Shareholder Meeting, (c) that, in all other respects, the terms,
    restrictions and conditions of the Articles of Incorporation and By-Laws of
    the Company, including quorum requirements and all other matters, shall
    apply in respect of the Company Shareholder Meeting: and (d) for the grant
    of the rights of dissent in respect of the Arrangement described in Section
    3.1 of the Plan of Arrangement.
 
        2.1.2.  If the shareholders of the Company shall approve the Arrangement
    in accordance with the Interim Order, and subject to the satisfaction or
    waiver of the other conditions set forth in Article 8, the Company shall as
    promptly as practicable (a) take all necessary steps to submit the
    Arrangement to the Court and apply for a final order of the Court approving
    the Arrangement in such fashion as the Court may direct (the "Final Order"),
    and (b) send to the Director appointed under Section 260 of the CBCA (the
    "CBCA Director") for endorsement and filing by the CBCA Director, the
    Articles of Arrangement and such other documents as may be required in
    connection therewith under the CBCA to give effect to the Arrangement. At
    12:01 a.m. (the "Effective Time") on the date (the "Effective Date") shown
    on the Certificate of Arrangement issued by the Director giving effect to
    the Arrangement, the reorganization of capital and other transactions set
    out in clauses (a) through (k), inclusive, of Section 2.1 of the Plan of
    Arrangement shall occur and shall be deemed to occur in the order set forth
    in such Section 2.1 without any further act or formality.
 
    2.2.  EXCHANGE RATIO.
 
        2.2.1.  INITIAL EXCHANGE RATIO.  For purposes of the Plan of
    Arrangement, the "Exchange Ratio" shall be 0.1691 Exchangeable Shares for
    each Company Common Share, subject to adjustment in accordance with this
    Section 2.2.
 
        2.2.2.  ADJUSTMENT FOR ALTERATIONS OF EQUITY CAPITAL.  The Exchange
    Ratio shall be adjusted to reflect fully the effect of any stock split,
    reverse split, stock dividend (including any dividend or distribution of
    securities convertible into Parent Common Stock or Company Common Shares),
    reorganization, recapitalization or other like change with respect to Parent
    Common Stock or Company Common Shares occurring after the date hereof and
    prior to the Effective Time.
 
        2.2.3.  ADJUSTMENT FOR FLUCTUATIONS IN MARKET PRICE.  The Exchange Ratio
    shall also be adjusted pursuant to the following:
 
       (a) if the average of the per share closing prices on the Nasdaq National
           Market of shares of Parent Common Stock during the 20 consecutive
           trading days before the second Business Day before the Closing Date
           (as hereinafter defined) (the "Pre-Closing Average Price") shall be
           less than $25.375 per share, the Exchange Ratio shall be adjusted to
           equal the product of 0.1691 and a fraction, the numerator of which is
           $25.375 and the denominator of which is the greater of (i) $20.93 and
           (ii) the Pre-Closing Average Price; and
 

<PAGE>
       (b) if the Pre-Closing Average Price shall be greater than $25.375 per
           share, the Exchange Ratio shall be adjusted to equal the product of
           0.1691 and a fraction, the numerator of which is $25.375 and the
           denominator of which is the lesser of (i) $31.72 and (ii) the
           Pre-Closing Average Price.
 
        2.2.4.  CALCULATION OF ADJUSTMENTS.  Any adjustment of the Exchange
    Ratio pursuant to this Section 2.2 shall be rounded to four decimal places.
 
    2.3.  DISSENTING SHARES.  Holders of Company Common Shares may exercise
rights of dissent with respect to such shares in connection with the Arrangement
pursuant to and in the manner set forth in Section 190 of the CBCA and Section

and written notice of any written demands of a right of dissent, withdrawals of
such demands, and any other instruments served pursuant to the CBCA or otherwise
and received by the Company and (b) the opportunity to participate in all
negotiations and proceedings with respect to such rights. Without the prior

    Statement to become effective and to maintain the effectiveness of such
    Registration Statement for the period that such Exchangeable Shares shall
    remain outstanding. Parent, Subco and the Company agree not to knowingly
    take any action that would render unavailable the exemption provided by

    the Company will not waive, terminate or otherwise render the Rights
    Agreement inoperative or inapplicable with respect to any other Acquisition
    Proposal. At the Effective Time, the Rights Agreement will have been
    terminated, all rights will be canceled or redeemed pursuant to the Rights
    Agreement, and no Person shall have any rights thereunder.
 
    3.6.  SECURITIES REPORTS; FINANCIAL STATEMENTS.  The Company has timely

       (n) committed (orally or in writing) to do any of the foregoing.
 
        3.7.2.  LIABILITIES.  Neither the Company nor any of its Subsidiaries

Company Disclosure Schedule, there is no investigation or inquiry by any
Governmental Entity with respect to the Company or any of its Subsidiaries

its Subsidiaries an intention to conduct the same. Except as set forth in
Section 3.8 of the Company Disclosure Schedule, there is no claim, action, suit,
arbitration or proceeding pending or, to the knowledge of the Company or any of
its Subsidiaries, threatened against or involving the Company, any of its
Subsidiaries, or any of its or their assets or properties, at law or in equity,

to the Company or such Subsidiary, could result in a Company Material Adverse
Effect. There are no judgments, decrees, injunctions, orders or rulings of any
Governmental Entity or arbitrator outstanding against the Company or any of its
Subsidiaries.
 
    3.9.  COMPLIANCE WITH APPLICABLE LAW, ARTICLES OF INCORPORATION AND
BY-LAWS.  Each of the Company and its Subsidiaries has all requisite Permits
necessary to carry on its business as currently being conducted and to own,
lease and operate the properties currently owned, leased and operated by it in
the manner currently owned,
 

<PAGE>
leased and operated, except where the failure to have such Permits would not
result in a Company Material Adverse Effect. There are no proceedings pending
or, to the knowledge of the Company or any of its Subsidiaries, threatened,
which may result in the revocation, cancellation, suspension, or adverse
modification of any such Permit. The business of the Company and its
Subsidiaries has not been conducted in Violation of Applicable Laws, except for
Violations which, individually or in the aggregate, would not result in a
Company Material Adverse Effect. Neither the Company nor any of its Subsidiaries

Incorporation or By-Laws of the Company or any other organizational document of
the Company or any Subsidiary.

accounts of the Company and its Subsidiaries (a) have been maintained in
accordance with good business practices on a basis consistent with prior years,
(b) are stated in reasonable detail and accurately and fairly reflect in all
material respects the transactions and dispositions of the assets of the Company
and its Subsidiaries and (c) accurately and fairly reflect in all material
respects the basis for the Company's consolidated financial statements. The

sufficient to provide reasonable assurances that (d) transactions are executed
in accordance with management's general or specific authorizations; (e)

authorization; and (g) the recorded accountability for assets is compared with
the existing assets at reasonable intervals and appropriate action is taken with
respect to any differences. There has been no change in the Company's accounting
policies or the methods of making accounting estimates or changes in estimates
that are material to the Company's financial statements, except as described in
the notes thereto.
 
    3.11.  TAX MATTERS.
 
        3.11.1.  FILING OF RETURNS.  Each of the Company and its Subsidiaries
    has prepared and timely filed with all appropriate Governmental Entities all
    Tax Returns that it was required to file. All such Tax Returns were correct
    and complete in all respects. Neither the Company nor any of its
    Subsidiaries currently is the beneficiary of any extension of time within
    which to file any Tax Return, other than extensions for which the Company or
    any of its Subsidiaries has filed a request, which request has resulted in
    the automatic granting of such extension. No Governmental Entity in any
    jurisdiction in which any of the Company and its Subsidiaries does not file
    Tax Returns has ever claimed that the Company or any of its Subsidiaries is
    or may be subject to taxation by that jurisdiction.
 
        3.11.2.  PAYMENT OF TAXES.  All Taxes payable or owed by the Company and
    its Subsidiaries (whether or not shown on any Tax Return) have been paid
    when due, and all Taxes due on or before the Effective Date will be paid
    when due. In the case of Taxes accruing on or before the date hereof that
    are not due on or before date hereof, the Company has made adequate
    provision in its books and records and financial statements for such
    payment. There are no security interests on any of the assets of any of the
    Company and its Subsidiaries that arose in connection with any failure (or
    alleged failure) to pay any Tax.
 
        3.11.3.  WITHHOLDING.  Each of the Company and its Subsidiaries has
    withheld from each payment made to any of its present or former employees,
    officers, directors, stockholders, non-residents and other Persons all
    amounts required by Law to be withheld and has, where required, remitted
    such amounts within the applicable periods to the appropriate Governmental
    Entity.
 
        3.11.4.  ASSESSMENTS.  Neither the Company nor any of its Subsidiaries
    expects any authority to assess any additional Taxes in excess of tax
    reserves provided for in the Company's financial statements against the
    Company or any of its Subsidiaries for any period for which Tax Returns have
    been filed. No Tax Return of the Company or any of its Subsidiaries has been
    audited or currently is the subject of audit. No Governmental Authority has
    raised any dispute or claim concerning any Tax liability of any of the
    Company and its Subsidiaries. Neither the Company nor any of its
    Subsidiaries has waived any statute of limitations in respect of Taxes or
    agreed to any extension of time with respect to a Tax assessment or
    deficiency.
 

<PAGE>
        3.11.5.  ELECTIONS AND CONSENTS.  Neither the Company nor any of its
    Subsidiaries has filed a consent pursuant to Section 341(f) of the Code
    relating to collapsible corporations, nor has the Company or any of its
    Subsidiaries agreed to have Section 341(f)(2) of the Code apply to any
    disposition of a subsection (f) asset (as such term is defined in Section
    341(f)(4) of the Code). Neither the Company nor any of its Subsidiaries has
    made any payments, is obligated to make any payments, or is a party to any
    agreement that under certain circumstances could obligate it to make any
    payments that will not be deductible under Section 280G of the Code. Neither
    the Company nor any of its Subsidiaries has been a United States real
    property holding corporation within the meaning of Section 897(c)(2) of the
    Code during the applicable period specified in Section 897(c)(1)(A)(ii) of
    the Code. Each of the Company and its Subsidiaries has disclosed on its
    United States income Tax Returns all positions taken therein that could give
    rise to a substantial understatement of federal income Tax within the
    meaning of Section 6662 of the Code. Neither the Company nor any of its
    Subsidiaries is a party to any Tax allocation or Tax sharing agreement. None
    of the Company and its Subsidiaries has been a member of an affiliated group
    filing a consolidated United States income Tax Return. Neither the Company
    nor any of its Subsidiaries has any material liability for the Taxes of any
    Person (other than the Company and its Subsidiaries) under Treasury
    Regulation Section 1.1502-6 (or any similar provision of any other
    Applicable Law), as a transferee or successor, by contract, or otherwise.
 
        3.11.6.  ACCESS TO RETURNS.  The Company has provided Parent with a copy
    of or access to all Canadian, United States and other federal, provincial,
    state, and local income and capital Tax returns filed by the Company and its
    Subsidiaries after January 1, 1994. The Company has provided Parent with a
    copy of or access to all assessments, extensions and waivers resulting from
    any examinations or audits of the Company or any of its Subsidiaries by a
    Governmental Entity in respect of Taxes, and all such assessments and
    related penalties and interest have been paid in full unless being contested
    in good faith by the Company or any of its Subsidiaries and described in
    Section 3.11 of the Company Disclosure Schedule.
 
    3.12.  EMPLOYEE BENEFIT PLANS.
 
        3.12.1.  LIST OF PLANS.  Section 3.12 of the Company Disclosure Schedule
    sets forth a complete list of all Company Benefit Plans sponsored or
    maintained by any Company Entity or under which any Company Entity is
    obligated. The Company has delivered to Parent (a) accurate and complete
    copies of all Company Benefit Plan documents and all other material
    documents relating thereto, including (if applicable) all summary plan
    descriptions, summary annual reports and insurance contracts, (b) accurate
    and complete detailed summaries of all unwritten Company Benefit Plans, (c)
    accurate and complete copies of the most recent financial statements and
    actuarial reports with respect to all Company Benefit Plans for which
    financial statements or actuarial reports are required or have been
    prepared, and (d) accurate and complete copies of all information returns
    and annual reports for all Company Benefit Plans (for which information
    returns or annual reports are required) prepared within the last three
    years, (e) all material professional opinions relating to the Company
    Benefit Plans and (f) accurate and complete copies of material
    correspondence with all regulatory authorities. No material changes have
    occurred or are expected to occur which would affect the actuarial reports
    or financial statements delivered to Parent pursuant to this Section 3.12.1.
    No Company Entity sponsors a defined benefit plan subject to Title IV of
    ERISA, nor does any Company Entity have a current or contingent obligation
    to contribute to any multiemployer plan (as defined in Section 3(37) of
    ERISA). No Company Entity has any liability with respect to any employee
    benefit plan (as defined in Section 3(3) of ERISA) other than with respect
    to the Company Benefit Plans.
 
        3.12.2.  ERISA COMPLIANCE.  All Company Benefit Plans conform (and at
    all times have conformed) in all material respects to, and are being
    administered and operated (and have at all time been administered and
    operated) in material compliance with, the requirements of ERISA, the Code
    and all other Applicable Laws. All returns, reports and disclosure
    statements required to be made under ERISA and the Code with respect to all
    Company Benefit Plans have been timely filed or delivered. There have not
    been any "prohibited transactions," as such term is defined in Section 4975
    of the Code or Section 406 of ERISA, involving any of the Company Benefit
    Plans that could subject any Company Entity to any material penalty or tax
    imposed under ERISA or the Code.
 

<PAGE>
        3.12.3.  PLAN DETERMINATIONS.  Any Company Benefit Plan that was or is
    intended to be qualified under Section 401(a) of the Code and exempt from
    tax under Section 501(a) of the Code has been determined by the Internal
    Revenue Service to be so qualified or an application for such determination
    is pending. Any such determination that has been obtained remains in effect
    and has not been revoked, and with respect to any application that is
    pending, no Company Entity has any reason to suspect that such application
    for determination will be denied. Nothing has occurred since the date of any
    such determination that is reasonably likely to affect adversely such
    qualification or exemption, or result in the imposition of excise taxes or
    income taxes on unrelated business income under ERISA or the Code with
    respect to any Company Benefit Plan.
 
        3.12.4.  CLAIMS.  There are no pending or, to the knowledge of any
    Company Entity, threatened claims by or on behalf of any Company Benefit
    Plans, or by or on behalf of any individual participants or beneficiaries of
    any Company Benefit Plans, alleging any breach of fiduciary duty on the part
    of any Company Entity or any of its officers, directors or employees under
    ERISA or any other applicable regulations, or claiming benefit payments
    (other than those made in the ordinary operation of such plans), nor is
    there, to the knowledge of any Company Entity, any basis for such claim. The
    Company Benefit Plans are not the subject of any pending, or, to the
    knowledge of any Company Entity, threatened investigation or audit by the
    Internal Revenue Service, the Department of Labor or the Pension Benefit
    Guaranty Corporation ("PBGC").
 
        3.12.5.  CONTRIBUTIONS.  Each Company Entity has timely made all
    required contributions under the Company Benefit Plans, including the
    payment of any premiums payable to the PBGC and other insurance premiums.
 
        3.12.6.  WELFARE PLANS.  With respect to any Company Benefit Plan that
    is an employee welfare benefit plan (within the meaning of Section 3(1) of
    ERISA) (a "Welfare Plan") (a) each Welfare Plan for which contributions are
    claimed by any Company Entity as deductions under any provision of the Code
    is in material compliance with all applicable requirements pertaining to
    such deduction, (b) with respect to any welfare benefit fund (within the
    meaning of Section 419 of the Code) related to a Welfare Plan, there is no
    disqualified benefit (within the meaning of Section 4976(b) of the Code)
    that would result in the imposition of a tax under Section 4976(a) of the
    Code, (c) any Company Benefit Plan that is a group health plan (within the
    meaning of Section 4980B(g)(2) of the Code) complies, and in each and every
    case has complied, with all of the applicable material requirements of
    Section 4980B of the Code, ERISA, Title XXII of the Public Health Service
    Act and the Social Security Act, and (d) all Welfare Plans may be amended or
    terminated at any time on or after the Effective Date. No Company Benefit
    Plan provides any health, life or other welfare coverage to employees of any
    Company Entity beyond termination of their employment with the Company or
    any of its Subsidiaries by reason or retirement or otherwise, other than
    coverage as may be required under Section 4980B of the Code or Part 6 of
    ERISA, or under the continuation of coverage provisions of the Laws of any
    state, province, territory or locality.
 
        3.12.7.  CANADIAN BENEFIT PLANS.  All of the Company Benefit Plans in
    which Canadian employees of the Company Entities participate or are eligible
    to participate (the "Canadian Plans") are and have been established,
    registered, qualified, invested and administered in all respects in
    accordance with all laws, regulations, orders or other legislative,
    administrative or judicial promulgations applicable to the Canadian Plans.
    No fact or circumstance exists that could adversely affect the tax-exempt
    status of a Canadian Plan. All obligations regarding the Canadian Plans have
    been satisfied and there are no actions, outstanding defaults or violations
    by any party to any Canadian Plan that could subject any Company Entity
    (including any Canadian Plan or fund held in connection therewith) to any
    material penalty or Tax, and no Tax, penalty or fee is owing or exigible
    under or in respect of any Canadian Plan. A Company Entity may unilaterally
    amend, modify, vary revoke or terminate, in whole or in part, any Canadian
    Plan maintained by it and take contribution holidays under or withdraw
    surplus from such Canadian Plans, subject only to approvals required by
    Applicable Laws. Subject to Applicable Laws, a Company Entity may amend,
    revise or merge any Canadian Plan or transfer or merge the assets or
    liabilities of any Canadian Plan with any other arrangement, plan or fund.
    No Canadian Plan, nor any related trust or other funding medium thereunder,
    is subject to any pending investigation, examination or other proceeding,
    action or claim initiated by any Governmental Entity, or by any other party
    (other than routine claims for benefits), and there exists no
 

<PAGE>
    state of facts which after notice or lapse of time or both could reasonably
    be expected to give rise to any such investigation, examination or other
    proceeding, action or claim or to affect the registration of any Canadian
    Plan required to be registered. All contributions or premiums required to be
    made by a Company Entity under the terms of a Canadian Plan or by Applicable
    Laws have been made in a timely fashion in accordance with Applicable Laws
    and the terms of the Canadian Plan, and no Company Entity has, and as of the
    Effective Time will not have, any liability (other than liabilities accruing
    after the Effective Time) with respect to any of the Canadian Plans.
    Contributions or premiums will be paid by the applicable Company Entity on
    an accrual basis for the period up to the Effective Time even though not
    otherwise required to be made until a later date. No amendments have been
    made to any Canadian Plan and no improvements to any Canadian Plan have been
    promised and no amendments or improvements to any Canadian Plan will be made
    or promised by a Company Entity before the Effective Time. There have been
    no improper withdrawals, applications or transfers of assets from any
    Canadian Plan or the trusts or other funding media relating thereto, and no
    Company Entity or any agent of a Company Entity has been in breach of any
    fiduciary obligation with respect to the administration of the Canadian
    Plans or the trusts or other funding media relating thereto. Each Canadian
    Plan is fully funded or fully insured on both an ongoing and solvency basis.
    No Canadian Plan enjoys any special tax status under Applicable Laws, nor
    have any advance tax rulings or interpretations been sought or received in
    respect of the Canadian Plans. All employee data necessary to administer
    each Canadian Plan has been provided to the Parent and is true and correct.
    No insurance policy or other contract or agreement affecting any Canadian
    Plan requires or permits a retroactive increase in premiums or payments due
    thereunder. The level of insurance reserves under each insured Canadian Plan
    is reasonable and sufficient to provide for all incurred claims. No Canadian
    Plan provides benefits to retired employees or to the beneficiaries or
    dependents of retired employees. No Canadian Plan is a plan or arrangement
    to which more than one employer that is not a Company Entity is required or
    permitted to contribute and no Canadian Plan is a multi-employer plan.
 
    3.13.  EMPLOYMENT-RELATED MATTERS.  Neither the Company nor any of its
Subsidiaries is a party to any collective bargaining agreement or other contract
or agreement with any labor organization or other representative of any of the
employees of the Company or any of its Subsidiaries, nor are any of such
contracts or agreements pending or contemplated. There is no labor strike,
dispute, slowdown, work stoppage or lockout that is pending or, to the knowledge
of the Company or any of its Subsidiaries, threatened against or otherwise
affecting the Company or any of its Subsidiaries, and neither the Company nor
any of its Subsidiaries has experienced the same since January 1, 1992. Except
as set forth in Section 3.13 of the Company Disclosure Schedule, neither the
Company nor any of its Subsidiaries has closed any plant or facility,
effectuated any layoffs of employees or implemented any early retirement or
separation program at any time from or after January 1, 1992, nor has the
Company or any of its Subsidiaries planned or announced any such action or
program for the future with respect to which the Company or any of its
Subsidiaries may have any liability. All salaries, wages, vacation pay, bonuses,
commissions and other compensation payable by the Company or any of its
Subsidiaries to the employees of the Company or any of its Subsidiaries before
the date hereof have been paid in all material respects as of the date hereof.
No Person has asserted any claim, or, to the knowledge of the Company or any of
its Subsidiaries, has any reasonable basis to assert any valid claim, against
the Company or any of its Subsidiaries that either the continued employment by,
or association with, the Company or any of its Subsidiaries of any of the
present officers or employees of, or consultants to, the Company or any of its
Subsidiaries contravenes any agreements or Laws applicable to unfair
competition, trade secrets or proprietary information.
 
    3.14.  ENVIRONMENTAL.
 
        3.14.1.  ENVIRONMENTAL LAWS.  The Company and its Subsidiaries are in
    compliance in all material respects with all applicable Environmental Laws.
    Neither the Company nor any of its Subsidiaries has received any
    communication that alleged that the Company or any of its Subsidiaries was
    or is not in compliance in all respects with or has any liability under any
    applicable Environmental Law. To the knowledge of the Company or any of its
    Subsidiaries, there are no circumstances that may prevent or interfere with
    compliance in the future with all applicable Environmental Laws. All Permits
    currently held by the Company or any of its Subsidiaries pursuant to
    Environmental Laws are in full force and effect. The Company and its
    Subsidiaries are in compliance in all material respects with all of the
    terms of such Permits, and, to the knowledge of the Company or any of its
    Subsidiaries, no other Permits are required by

    Subsidiaries nor, to the knowledge of the Company or any of its

    of the Company and its Subsidiaries as currently conducted by the Company
    and its Subsidiaries (the "Company Proprietary Rights"), free and clear of
    any and all Encumbrances. To the knowledge of the Company or any of its
    Subsidiaries, there is no reason why the Company and its Subsidiaries will
    not be able to continue to own or have perpetual, fully paid, worldwide
    rights to use all Company Proprietary Rights necessary for the lawful
    conduct of its or their business as currently conducted and as currently
    proposed to be conducted, without any infringement or conflict with the

    license, sublicense or agreement included in such list, except for
    violations that do not materially impair the rights of the Company or any of
    its Subsidiaries under such license, sublicense or agreement. Such licenses,
    sublicenses and agreements are in full force and effect and are binding and
    enforceable against each of the parties thereto in accordance with their
    respective terms. The execution and delivery by the Company of this
    Agreement, the Plan of Arrangement and the other agreements contemplated
    hereby, the performance by the Company of its obligations hereunder and
    thereunder, and the consummation by the Company of the transactions
    contemplated hereby and thereby will not cause the Company or any of its
 

<PAGE>
    Subsidiaries to be in violation or default under any such license,
    sublicense or agreement, nor entitle any other party to any such license,
    sublicense or agreement to terminate or modify such license, sublicense or
    agreement.

    Subsidiaries have diligently protected their rights in the Company
    Proprietary Rights in such countries and have diligently maintained the
    confidentiality of their trade secrets, know-how and other confidential
    Company Proprietary Rights, and, to the knowledge of the Company or any of
    its Subsidiaries, there have been no acts or omissions by the Company or any
    of its Subsidiaries, the result of which has been or would be to compromise
    the rights of the Company or any of its Subsidiaries to apply for or enforce
    appropriate legal protection of such Company Proprietary Rights. Without
    limiting the generality of the foregoing, the products, packaging and
    documentation of the Company and its Subsidiaries contain copyright notices
    sufficient to maintain copyright protection on the copyrighted portions of
    the Company Proprietary Rights.
 
        3.17.6.  NO CONFLICT.  Except as set forth in Section 3.17.6 of the
    Company Disclosure Schedule, no claims with respect to the Company
    Proprietary Rights are pending, have been asserted or, to the knowledge of
    the Company or any of its Subsidiaries, are threatened by any Person nor, to
    the knowledge of the Company or any of its Subsidiaries, are there any valid
    grounds for any BONA FIDE claims (a) to the effect that the development,
    sale, licensing or use of any of the products of the Company and its
    Subsidiaries as now developed, sold, licensed or used or proposed for
    development, sale, licensing or use by the Company and its Subsidiaries
    infringes on any patent, industrial design, trademark, trade name, service
    mark, copyright, trade secret or other proprietary right of any Person, (b)
    against the use by the Company or any of its Subsidiaries of any patents,
    industrial designs, trademarks, trade names, service marks, copyrights, and

    know-how, trade secrets, algorithms, computer software programs or
    applications, and tangible or intangible proprietary information or material
    used in the business of the Company and its Subsidiaries as currently
    conducted or as proposed to be conducted by the Company and its
    Subsidiaries, or (c) challenging the ownership by the Company or any of its
    Subsidiaries of, the validity of any registration for, any application
    relating to, or the effectiveness any of the Company Proprietary Rights. To
    the knowledge of the Company or any of its Subsidiaries, there is no
    unauthorized use, infringement or misappropriation of any of the Company
    Proprietary Rights by any third party, including any employee or former
    employee of the Company or any of its Subsidiaries. No Company Proprietary
    Right or product of the Company or any of its Subsidiaries is subject to any
    outstanding decree, order, judgment, or stipulation restricting in any
    manner the use or licensing thereof by the Company or any of its
    Subsidiaries.

    confidentiality agreements executed and delivered by such employees,
    officers and consultants and Applicable Laws provide the Company and its
    Subsidiaries with title and ownership to the Company Proprietary Rights
    developed by such employees, officers and consultants, including the waiver
    of their moral rights in favor of the Company or its Subsidiaries and their
    respective successors and assigns, and obligate such employees, officers and
    consultants to maintain the confidentiality of the Company Proprietary
    Rights and the other confidential information of the Company and its

    proprietary information and inventions agreement, non-competition agreement,
    or any other contract or agreement relating to the relationship of any such
    employee, officer or consultant with the Company, any of its Subsidiaries or
    any previous employer.

    Schedule identifies each "year 2000" audit, report or investigation that has

<PAGE>
    of its Subsidiaries with respect to its business and operations, and the
    Company has provided to Parent true and correct copies of all such audits,
    reports or investigations. Except as set forth in such audits, reports and
    investigations or in Section 3.17.8 of the Company Disclosure Schedule,
    neither the Company nor any of its Subsidiaries is aware of any failure to
    be Year 2000 Compliant of (a) any software products sold or licensed by the
    Company or any of its Subsidiaries or (b) any computer software or hardware
    products used by or licensed to the Company or its Subsidiaries from third
    parties for internal use by the Company or its Subsidiaries. For purposes of
    this Agreement, "Year 2000 Compliant" means, with respect to each product

    data from, during, into and between the twentieth and twenty-first

    systems used in conjunction with such system which are not owned or licensed
    by the Company or any of its Subsidiaries correctly exchange date data with
    or provide data to such system. Except as set forth in Section 3.17.8 of the
    Company Disclosure Schedule, neither the Company nor any of its Subsidiaries
    has provided any guarantee or warranty for any product sold or licensed, or
    services provided, by the Company or any of its Subsidiaries to the effect
    that such product or service (f) complies with or accounts for the fact of
    the arrival of the year 2000 or (g) will not be adversely affected with
    respect to functional interoperability, performance or volume capacity
    (including the processing and reporting of data) by virtue of the arrival of

Insurance Contracts") insure against such risks, and are in such amounts, as are
reasonable and appropriate considering the Company and its Subsidiaries and
their property, business and operations. Except as set forth in Section 3.19 of
the Company Disclosure Schedule, all of the Company Insurance Contracts are in
full force and effect, with no default thereunder by the Company or any of its
Subsidiaries which could permit the insurer to deny payment of claims
thereunder. The execution and delivery by the Company of this Agreement and the
other agreements contemplated hereby, the performance by the Company of its
obligations hereunder and thereunder, and the consummation by the Company of the
Plan of Arrangement and the other transactions contemplated hereby and thereby
will not cause the Company or any of its Subsidiaries to be in Violation of any
Company Insurance Contracts, nor entitle any other party thereto to terminate or
modify a Company Insurance Contract. Neither the Company nor any of its
Subsidiaries has received notice from any of their insurance carriers that any
insurance premiums will be materially increased in the future or that any
insurance coverage provided under the Company Insurance Contracts will not be
available in the future on substantially the same terms as now in effect.

Company and its Subsidiaries with their suppliers, distributors and customers
are satisfactory commercial working relationships. Except as set forth in
Section 3.21 of the Company Disclosure Schedule, since the date of the Company
Balance Sheet, no material supplier, distributor or customer of the Company or
any of its Subsidiaries has canceled or otherwise adversely modified its
relationship with the Company or any of its Subsidiaries and, to the knowledge
of the Company or any of its Subsidiaries, no supplier, distributor or customer
of the Company or any of its Subsidiaries has any intention to do so, and, to
the knowledge of the Company or any of its Subsidiaries, none of the execution
and delivery by the Company of this Agreement and the other agreements
contemplated hereby, the performance by the Company of its obligations hereunder
and thereunder, and the consummation by the Company of the Plan of Arrangement
and the other transactions contemplated hereby and thereby will materially
adversely affect any such relationship.
 
    3.22.  PRODUCT WARRANTY.  Each product sold, leased, licensed or delivered
by the Company or any of its Subsidiaries has been in material conformity with
all applicable contractual commitments and all express and implied warranties,
and neither the Company nor any of its Subsidiaries has any Liability,
individually or in the aggregate (and, to the knowledge of the Company or any of
its Subsidiaries, there is no basis for any present or future action, suit,
proceeding, hearing, investigation, charge, complaint, claim, or demand giving
rise to any Liability, individually or in the aggregate, that could reasonably
be expected to result in a Company Material Adverse Effect) for replacement or
repair thereof or other damages in connection therewith that could result in a
Company Material Adverse Effect. Section 3.22 of the Company Disclosure Schedule

Company and its Subsidiaries (containing applicable warranty and indemnity

Section 3.22 of the Company Disclosure Schedule.
 
    3.23.  INVESTMENT CANADA.  The Company and its Subsidiaries do not carry on
a business of the publication, distribution or sale of books, magazines or

tangible and intangible assets and properties heretofore used or necessary for
the normal continued conduct of the business of the Company and its Subsidiaries
as now conducted and as proposed to be conducted.
 
    3.25.  DIRECTOR APPROVAL.  The Board of Directors of the Company has (a)
determined unanimously that the Arrangement is fair to the holders of Company

    3.28.  POOLING MATTERS.  Neither the Company nor any of its Affiliates has
knowingly taken or agreed to take any action that, without giving effect to any
action taken or agreed to be taken by Parent or any of its Affiliates, would
prevent Parent from accounting for the business combination to be effected by
the Arrangement as a pooling of interests. The Company's Board of Directors has
received a letter from Ernst & Young LLP to the effect that, based on its
evaluation of the information provided by the Company with respect to the
business combination to be effected by the Arrangement, Ernst & Young LLP
expects to be able to deliver on the Effective Date a written report (the
"Company Pooling Opinion") generally to the effect that Ernst & Young LLP
concurs with management's conclusions that no condition exists that would
preclude the Company from being a party to a business combination for which the
pooling of interests method of accounting would be available.
 
    3.29.  FAIRNESS OPINION.  The Company's Board of Directors has received the
written opinion of Griffiths McBurney & Partners (the "Company Fairness

its Subsidiaries, there is no fact existing on the date hereof that the Company
has not disclosed to Parent in writing that could result in a Company Material
Adverse Effect.

    Arrangement and the other transactions contemplated hereby and thereby will
    cause a Violation of any term, condition or provision of the Articles of

from Ernst & Young LLP with respect to the business combination to be effected
by the Arrangement, a letter (the "Parent Pooling Opinion") generally to the

all of such party's and its Subsidiaries' properties, books, contracts,
commitments and records. During such period, each party shall use reasonable
efforts to furnish promptly to the other party all other information concerning

necessary to verify the representations and warranties of the other party or
parties.

    to the extent that such document or information: (a) at the time of its
    disclosure to the receiving party or its Representatives by the disclosing
    party or its Representatives is already known or available to the receiving
    party or its Representatives (but this Agreement shall not relieve the
    receiving party from any obligations of confidentiality owed to third
    parties with respect to such information); (b) is or becomes known or
    available to the public other than as a result of an unauthorized disclosure
    by the receiving party or its Representatives; (c) is or becomes known or
    available to the receiving party or its Representatives without restrictions

    bound by a confidentiality agreement with, or other obligation of secrecy
    to, the disclosing party or its Representatives that would prohibit such
    disclosures to the receiving party or its Representatives by such source;
    (d) is independently generated by the receiving party or its Representatives
    and not derived from confidential information; or (e) is required to be
    disclosed by the receiving party or its Representatives by Applicable Law or
    other legal process. Subject to the foregoing, each party and its
    Representatives shall not release or disclose such documents or information
    to any Person other than those Representatives of such party that need to
    review such documents or know such information in order to perform their
    duties in connection with this Agreement and shall not use such documents or
    information for purposes other than as contemplated hereby. In the event of
    the termination of this Agreement, (f) each party shall, and shall cause its
    Representatives to, deliver to the other party the originals of all
    documents obtained by such party or its Representatives from the other party
    or its Representatives in connection with this Agreement, whether so
    obtained before or after the execution hereof, (g) such party shall, and
    shall cause its Representatives to, destroy all copies thereof and (h)
    within 30 days of such termination, such party shall certify to the other in
    writing that such party and its Representatives shall have complied with
    their obligations in this sentence.
 
        7.4.2.  ACTIONS OF REPRESENTATIVES.  Each party shall ensure that its
    Representatives are aware of the provisions of this Section 7.4, and it

    survive any termination of this Agreement and remain in effect for a period
    of one year from the date hereof.
 
    7.5.  PUBLIC DISCLOSURE.  Any press release or other public disclosure of
information regarding the transactions contemplated hereby (including the
existence and terms of this Agreement) shall be developed jointly by Parent and
the Company; PROVIDED, HOWEVER, that if Applicable Law shall require either
party to disclose publicly any such information, such party may disclose
publicly such information after reasonable consultation with the other party.
 
    7.6.  TAKEOVER AND OTHER LAWS.  If any takeover Law or other Law shall
become applicable to the transactions contemplated hereby, the Company and its
Board of Directors or Parent and its Board of Directors, as the case may be,
shall use their reasonable best efforts to obtain such approvals and take such
actions as are necessary so that the transactions contemplated hereby may be
consummated as promptly as practicable on the terms contemplated hereby and
otherwise to minimize the effects of such takeover Law or other Law on the
transactions contemplated hereby.
 
    7.7.  POOLING ACCOUNTING.  Each of Parent and the Company shall use its
reasonable best efforts to cause the business combination to be effected by the
Arrangement to be accounted for as a pooling of interests and to cause their
respective Affiliates not to take any action that would adversely affect the
ability of Parent to account for such business combination as a pooling of
interests.

    information of the Company shall be included in the Registration Statement,

    registration statements similar to the Information Circular and the
    Registration Statement, as the case may be.
 
        7.8.2.  PARENT.  Parent shall use its reasonable best efforts to cause
    PricewaterhouseCoopers LLP to deliver to the Company a letter addressed to
    the Company with respect to the financial information of Parent contained in

    Parent Comfort Letter shall be required, the Second Parent Comfort Letter
    shall be dated as of a date within five days before the date on which the
    Registration Statement shall become effective. The Parent Comfort Letters

    customary in scope and substance for "comfort" letters delivered by
    independent public accountants in connection with proxy statements and
    registration statements similar to the Information Circular and the
    Registration Statement, as the case may be.
 
    7.9.  NOTICE OF CERTAIN MATTERS.  Each of Parent (including Subco) and the
Company shall promptly notify the other in writing (i) if such party shall
become aware that any of such party's representations and warranties in this
Agreement is untrue or inaccurate in any material respect, (ii) if there shall

    Option shall have, and be subject to, the same terms and conditions of such
    Company Option as before the Effective Time. Any adjustments pursuant to the

    shall take all corporate action necessary to reserve for issuance a
    sufficient number of shares of Parent Common Stock for delivery upon

    as so exchanged, and shall maintain, in the same manner as Parent's
    registration statements for its stock plans, the effectiveness of such

    7.11.  CONTINUATION OF INDEMNIFICATION AND INSURANCE.
 
        7.11.1.  INDEMNIFICATION.  Parent and the Company agree that the
    indemnification obligations set forth in the Company's Articles of
    Incorporation and By-Laws and similar documents of any of the Company's
    Subsidiaries in effect on the date of this Agreement shall, with respect to
    matters occurring prior to the Effective Time, survive after the Effective
    Time and, for a period of not less than the statutes of limitations
    applicable to such matters, shall not be amended, repealed or otherwise
    modified in any manner that would adversely affect the rights thereunder of
    the individuals entitled to indemnification thereunder immediately before
    the Effective Time (the "Beneficiaries").
 
        7.11.2.  INSURANCE.  For a period of three years after the Effective
    Time, Parent shall continue in effect the Company's director and officer
    liability insurance (or obtain other insurance which is comparable in all
    material respects) for the benefit of the persons presently entitled to
    coverage thereunder in such amounts, and with such deductibles, retained
    amounts, coverages and exclusions as the Company shall provide for its
    directors and officers on the date hereof; PROVIDED, that in no event shall
    Parent or the Company be required to expend in excess of 150% of the annual
    premium currently paid by the Company for such coverage or such coverage as
    shall be available for 150% of such annual premium.
 
        7.11.3.  THIRD-PARTY BENEFICIARIES.  After the Effective Time, Parent
    shall cause the Company and its Subsidiaries to perform its and their
    obligations under this Section 7.11 and to fulfill its and their
 

<PAGE>
    indemnification obligations under its and their respective organizational
    documents. The obligations of Parent and the Company under this Section 7.11
    shall not be amended, terminated or modified in any manner that would
    adversely affect the rights of any Beneficiary without the consent of such
    Beneficiary. Parent and the Company agree that each such Beneficiary shall
    be a third-party beneficiary of this Section 7.11.
 
    7.12.  EMPLOYEE BENEFIT MATTERS.  To the extent permitted under the terms of
the applicable Company Benefit Plans, Parent shall maintain the Company Benefit
Plans until December 31, 1999 and shall provide any notices required under
Applicable Law with respect to changes thereto; PROVIDED, HOWEVER, that Parent
may discontinue a Company Benefit Plan if Parent shall provide or make available
benefits to the beneficiaries of such Company Benefit Plan that are not
materially less favorable than the benefits available under such Company Benefit
Plan. To the extent permitted under the terms of the applicable Parent benefit
plans, all employees of the Company and its Subsidiaries shall be eligible,
after the Effective Time, to participate in the various benefit plans and
programs maintained for Parent employees or in substantially similar programs,
including any of the following benefit plans maintained by Parent as of the
Effective Time: health/medical/ dental/vision care, life insurance, disability
income, sick pay, holiday and vacation pay, 401(k) plan coverage, Section 125
benefit arrangements, Group RRSP, bonus, profit-sharing or other incentive
plans, pension or retirement programs, dependent care assistance, and employee
stock option and stock purchase plans, to the extent the employees of the
Company and its Subsidiaries meet the eligibility requirements for each such
plan or program. To the extent permitted under the terms of such plans, the
employees of the Company and its Subsidiaries shall be given credit, for
purposes of any service requirements for establishing eligibility for
participation or benefits (and not for purposes of calculating benefits) for
their period of service with the Company and its Subsidiaries prior to the
Effective Time, and the employees of the Company and its Subsidiaries shall
also, with respect to any Parent plans or programs which have co-payment,
deductible or other co-insurance features, receive credit for any amounts such
employees have paid as of the Effective Time in the plan year of the Arrangement
in co-payments, deductibles or co-insurance under comparable programs maintained
by the Company or any of its Subsidiaries prior to the Effective Time. To the
extent permitted under the terms of such plans, no employee of the Company and
its Subsidiaries who participates in any health/ medical/dental/vision plan of
the Company or any of its Subsidiaries at the Effective Time shall be denied
coverage under the Parent health/medical/dental/vision plans by reason of any
pre-existing condition exclusions. Notwithstanding the foregoing, this Section
7.12 shall not require Parent to take any action, or refrain from taking any
action, that would adversely affect its ability to account for the business
combination to be effected by the Arrangement as a pooling of interests.
 
    7.13.  OBLIGATIONS OF SUBCO.  Parent shall take all action necessary to
cause Subco to perform its obligations under this Agreement and to consummate

the Company shall deliver to Parent an executed option agreement in the form of

Agreement, each of Parent and the Company shall provide the other with a list of
each Person who is, or may be deemed to be, an Affiliate of Parent (a "Parent
Affiliate") or the Company (a "Company Affiliate"), as the case may be, and
shall cause each such Parent Affiliate or Company Affiliate, respectively, to
deliver, simultaneously with the execution of this Agreement, to the other an
executed agreement in the form of EXHIBIT F (a "Parent Affiliate Agreement") or
EXHIBIT G (a "Company Affiliate Agreement") hereto, respectively. Each of Parent
and the Company shall notify the other if any Person not on the list provided to
the other pursuant to this Section 7.15 shall become, or shall be deemed to be,
a Parent Affiliate or a Company Affiliate, respectively, and shall cause each
such Person to deliver to the other an executed Parent Affiliate Agreement or a
Company Affiliate Agreement, respectively.
 
    7.16.  SHAREHOLDER AGREEMENTS.  Simultaneously with the execution of this
Agreement, the Company shall cause certain shareholders of the Company
identified by Parent and each of the Company's directors, officers and their
investment affiliates to deliver to Parent an executed Shareholder Agreement in
the form of EXHIBIT H (collectively, the Shareholder Agreements") (including the
irrevocable proxy attached thereto).
 

<PAGE>

Agreement, the Company shall cause each employee designated by Parent to deliver

take such action as shall be necessary to elect Mr. Ian McKinnon as Vice
President and General Manager of Parent's Software Division, such election to be
effective on the Effective Date or as soon thereafter as practicable.
 
    7.19.  COVENANTS REGARDING NON-SOLICITATION.
 
        7.19.1.  NON-SOLICITATION.  Until the Effective Time, neither the
    Company nor any of its Subsidiaries shall, directly or indirectly, through
    any Representative or otherwise, (a) solicit, initiate, encourage or take
    any other action to facilitate (including by way of disclosing information,
    affording access to the properties, books or records of the Company or any
    of its Subsidiaries, or entering into any agreement, arrangement or
    understanding) the making of any inquiry, proposal or offer that constitutes
    or could be expected to lead to an Acquisition Proposal, (b) participate in
    any discussions or negotiations regarding any Acquisition Proposal, (c)
    withdraw, or modify in a manner adverse to Parent, the approval of the
    Company's Board of Directors of the transactions contemplated hereby or make
    or authorize any statement, recommendation or solicitation in support of any
    Acquisition Proposal, (d) approve or accept any Acquisition Proposal or (e)
    cause the Company to enter into any agreement related to any Acquisition
    Proposal. The Company and its Subsidiaries shall immediately cease any and
    all existing solicitations, initiations, encouragements, activities,
    discussions or negotiations with any Person (other than Parent and Subco)
    with respect to the foregoing. Notwithstanding the foregoing, the Company
    may, in response to an unsolicited tender or exchange offer, comply with its
    obligations under Applicable securities Laws relating to the provision of
    directors' circulars and disclosures to the Company's securityholders.
 
        7.19.2.  COMPLIANCE WITH FIDUCIARY OBLIGATIONS.  Subject to compliance
    with the terms of Sections 7.19.3, 7.19.4 and 7.20 and notwithstanding any
    other provision of this Agreement, the Company, its Subsidiaries and its
    Representatives may, at any time prior to the approval of the Arrangement by
    the Company's securityholders, take any action with respect to an
    Acquisition Proposal received by the Company that would otherwise be
    prohibited by Section 7.19.1 if, and only to the extent that, (a) the
    Acquisition Proposal shall be an unsolicited BONA FIDE written Acquisition
    Proposal, (b) after receiving the written advice of the Company's financial
    advisors and after receiving a written opinion of outside counsel to the
    effect that the fiduciary duties of the Company's Board of Directors require
    such Board to take such action in order to discharge properly its fiduciary
    duties, the Company's Board of Directors shall have reasonably determined in
    good faith that such Acquisition Proposal (i) would result in a transaction
    that (A) is more favorable from a financial point of view to the Company's
    securityholders than the transactions contemplated hereby and (B) has a
    value per Company Common Share greater than the value per Company Common
    Share of the transactions contemplated hereby, (ii) is a transaction for
    which financing, to the extent required, is then committed or which, in the
    good faith reasonable judgment of the Company's Board of Directors (based
    upon the good faith written advice of the Company's financial advisors), is
    capable of being financed by the Person or Persons making the Acquisition
    Proposal and (iii) if accepted by the Company, would be more likely than not
    to be consummated (any such Acquisition Proposal being referred to herein as
    a "Superior Proposal").
 
        7.19.3.  NOTICE TO PARENT OF ACQUISITION PROPOSALS.  The Company shall
    immediately notify Parent, at first orally and then in writing, of (a) all
    Acquisition Proposals of which any Representative of the Company and its
    Subsidiaries shall become aware, (b) any amendments to any Acquisition
    Proposal, (c) any request for information relating to the Company or any of
    its Subsidiaries or for access to the properties, books or records of the
    Company or any of its Subsidiaries by any Person that any Representative of
    the Company and its Subsidiaries knows, believes or suspects is considering
    making, or has made, an Acquisition Proposal (each, a "Bidder"). Such notice
    shall include a description of all of the terms and conditions of any
    proposal and provide such details of the proposal, request, inquiry or
    contact as Parent may request, including the identity of the Bidder. The
    Company shall keep Parent informed on a current basis of the status of any
    terms, discussions and negotiations in respect of each Acquisition Proposal.
 

<PAGE>
        7.19.4.  PROCEDURES.  The Company shall not, pursuant to Section 7.19.2,
    take any action prohibited by Section 7.19.1, unless at the time of the
    taking of such action the Company shall have (a) complied with Section
    7.19.3, (b) obtained from the Bidder a confidentiality agreement containing
    provisions substantially similar to those set forth in Section 7.4 of this
    Agreement, (c) delivered via facsimile a copy of such confidentiality
    agreement to Parent immediately upon its execution and (d) provided Parent
    with the same information and documents provided to the Bidder at the same
    time and in the same manner so provided (unless such information or
    documents shall have been previously provided to Parent, in which case the
    Company shall have provided Parent with a list of the information and
    documents provided to the Bidder).
 
        7.19.5.  ACTIONS OF REPRESENTATIVES.  The Company shall ensure that its
    Representatives are aware of the provisions of this Section 7.19, and it
    shall be responsible for any breach of this Section 7.19 by any such
    Representative.
 
    7.20.  PROCEDURES FOLLOWING SUPERIOR PROPOSAL DETERMINATION.
 
        7.20.1.  NOTICE OF SUPERIOR PROPOSAL DETERMINATION.  None of the
    Company, its Subsidiaries and its Representatives shall accept, approve,
    recommend or enter into any agreement in respect of any Acquisition Proposal
    (other than the confidentiality agreement contemplated by Section 7.19.4) on
    the basis that it would constitute a Superior Proposal unless (a) the
    Company shall have provided Parent with a copy of the Acquisition Proposal
    document that the Company's Board of Directors shall have determined would
    be a Superior Proposal, and (b) five Business Days shall have elapsed from
    the later of (i) the date Parent shall have received notice of the Company's
    proposed determination to accept, approve, recommend or enter into an
    agreement in respect of such Acquisition Proposal and (ii) the date Parent
    shall have received a copy of the Acquisition Proposal document.
 
        7.20.2.  OPPORTUNITY TO BID.  During such five Business Day period, the
    Company shall afford Parent the opportunity, in Parent's discretion, to
    offer to amend the terms of this Agreement and the Arrangement. The
    Company's Board of Directors shall convene a meeting to review in good faith
    any offer by Parent to amend the terms of this Agreement and the Arrangement
    in order to determine, in its discretion in the exercise of its fiduciary
    duties, whether Parent's offer upon acceptance by the Company would result
    in the Acquisition Proposal not being a Superior Proposal. If the Company's
    Board of Directors shall so determine, the Company shall enter into an
    amended agreement with Parent reflecting Parent's offer. If after such five
    Business Day period the Company's Board of Directors shall conclude, in good
    faith and after consultation with the Company's financial advisors and
    outside counsel, that the Acquisition Proposal is nonetheless a Superior
    Proposal and shall therefore reject Parent's offer, the Company shall pay to
    Parent the break-up fee payable to Parent under Section 9.4 as required
    thereunder. Each successive material amendment to any Acquisition Proposal
    shall constitute a new Acquisition Proposal for purposes of this Section
    7.20 and shall thereby initiate an additional five Business Day period under
    this Section 7.20.
 
    7.21.  MUTUAL STANDSTILL AND NON-SOLICITATION AGREEMENT.  For a period of
twelve months after the termination of this Agreement, if any, pursuant to
Article 9 of this Agreement, each of Parent and the Company agrees that it and
its Subsidiaries shall not (and each party and its Subsidiaries shall not assist
or encourage others to), and its Representatives shall not on its behalf (and
its Representatives shall not assist or encourage others on its behalf to),
directly or indirectly, unless specifically requested to do so by the other
party's Board of Directors (a) acquire, or agree or offer to acquire, or cause
to be acquired, ownership (including beneficial ownership as defined in Rule
13d-3 under the Exchange Act) of any of the other party's assets (other than in
the ordinary course of business) or businesses or any voting securities issued
by the other party, or any rights or options to acquire such ownership,
including from a third party; (b) make, or in any way participate in, any
solicitation of proxies or consents with respect to any securities of the other
party which are, or may be, entitled to vote in the election of the other
party's directors ("Voting Securities"), become a "participant" in any "election
contest" (as such terms are defined or used in Rule 14a-11 under the Exchange
Act) with respect to the other party, or to seek to advise, encourage or
influence any Person with respect to the voting of any Voting Securities; or
demand a copy of the other party's stock ledger, list of its stockholders or
other books and records; or call or attempt to call any meeting of the
stockholders of the other party; (c) enter into any discussions, negotiations,
arrangements or understandings with any third party (other than such party's
Representatives) with
 

<PAGE>
respect to any of the matters described in clauses (a) or (b) of this Section
7.21; or (d) induce or attempt to induce, directly or indirectly, any employee
or consultant of the other party to terminate his or her employment or
professional relationship with such other party (except by means of a general
solicitation of employees or consultants); PROVIDED, HOWEVER, that, nothing in
this Section 7.21 shall prevent the exercise of the Company Option or the taking
of any other action in accordance with the terms thereof.
 
    7.22.  EXPENSES.
 
        7.22.1.  GENERAL.  Except as set forth in this Section 7.22, all fees
    and expenses incurred in connection with this Agreement, the Arrangement and
    the other transactions contemplated hereby, including fees and disbursements
    of consultants, investment bankers and other financial advisors, counsel and
    accountants, the costs incurred in seeking necessary consents, financial
    printer expenses and filing fees, shall be paid by the party incurring such
    expenses, whether or not the Arrangement and the other transactions
    contemplated hereby are consummated.
 
        7.22.2.  REIMBURSEMENT.  If this Agreement shall be terminated pursuant
    to Section 9.1.2, 9.1.5, 9.1.7 or 9.1.9, the Company shall reimburse Parent
    for all of its reasonable out-of-pocket expenses, including fees and
    disbursements of consultants, investment bankers and other financial
    advisors, counsel and accountants, the costs incurred in seeking necessary
    consents, financial printer expenses and filing fees, incurred in connection
    with this Agreement, the Arrangement and the other transactions contemplated
    hereby ("Out-of-Pocket Expenses"), not to exceed $500,000. If this Agreement
    shall be terminated pursuant to Section 9.1.3 or 9.1.8, Parent shall
    reimburse the Company for all of its reasonable Out-of-Pocket Expenses, not
    to exceed $500,000. If this Agreement shall be terminated pursuant to
    Section 9.1.4 and the failure of a party to fulfill any material obligation
    under this Agreement shall have been the cause of, or shall have resulted
    in, the failure of the Effective Time to occur on or before the date
    specified in Section 9.1.4, then such party shall reimburse the other party
    for all of its reasonable Out-of-Pocket Expenses, not to exceed $500,000.

Section 9.1 (other than pursuant to Section 9.1.1) shall be effected by the
delivery of written notice of termination by the terminating party to the other
party hereto, which notice shall state the grounds for termination and the
subsection of Section 9.1 pursuant to which such terminating party shall be
terminating this Agreement.
 
    9.3.  EFFECT OF TERMINATION.  If either Parent or the Company shall
terminate this Agreement pursuant to Section 9.1, and the terminating party
shall have provided the notice required under Section 9.2 and paid the fee, if
any, required under Section 9.4, then this Agreement shall forthwith become void
and have no effect, and there shall be no liability or obligation under this
Agreement on the part of Parent, Subco or the Company or their respective
Representatives and stockholders, except that (a) the provisions of Section 7.4,
this Article 9 and Article 10 (and any defined terms used therein) shall survive
any such termination, and (b) no party shall be released or relieved from any
liability to the extent that such termination shall result from the breach by
such party of any of its representations, warranties, covenants or agreements in
this Agreement.
 
    9.4.  TERMINATION FEE.
 
        9.4.1.  If this Agreement shall be terminated pursuant to Section 9.1.5,
    9.1.7(a) or (b) (unless such action is a direct result of and in direct
    response to a material breach by Parent of any representation, warranty,
    covenant or agreement set forth in this Agreement or the occurrence of a
    Parent Material Adverse Effect), 9.1.7(c), 9.1.7(d) (unless, with respect to
    resolutions to take any of the actions specified in 9.1.7(a) or (b), such
    action is a direct result of and in direct response to a material breach by
    Parent of any representation, warranty, covenant or agreement set forth in
    this Agreement or the occurrence of a Parent Material Adverse Effect) or
    9.1.9, then the Company shall pay to Parent a cash termination fee of
    $1,330,000 (the "Termination Fee") at the time of such termination.
 
        9.4.2.  If this Agreement shall be terminated pursuant to Section 9.1.8
    (unless such action is a direct result of and in direct response to a
    material breach by the Company of any representation, warranty, covenant or
    agreement set forth in this Agreement or the occurrence of a Company
    Material Adverse Effect), then Parent shall pay to the Company the
    Termination Fee at the time of such termination.
 
        9.4.3.  Any Termination Fee payable pursuant to this Section 9.4 shall
    be paid not later than two Business Days after the delivery of written
    notice of termination pursuant to Section 9.2. Payment shall be made by wire
    transfer of immediately available funds to an account designated by the
    payee.
 
        9.4.4.  The payment by a party of any Termination Fee pursuant to this
    Section 9.4 shall be deemed to include payment of any expenses required to
    be paid by such party pursuant to Section 7.22.2.
 
        9.4.5.  Parent and the Company agree that it may be difficult and
    impractical to measure in money the damages that will accrue upon the
    termination of this Agreement pursuant to any provision of Section 9.1 that
    shall require the payment of a Termination Fee pursuant to this Section 9.4.
    Accordingly, Parent and the Company agree that payment of any Termination
    Fee payable pursuant to this Section 9.4 (together with any other amounts
    payable pursuant to this Section 9.4) shall (a) constitute liquidated
    damages and not a penalty, (b) be the sole and exclusive remedy of the payee
    of the Termination Fee for the breach of any representation, warranty,
    covenant or agreement in this Agreement by the payor and (c) constitute an
    irrevocable waiver and release by the payee of any other remedy against the
    payor for the breach of any representation, warranty, covenant or agreement
    in this Agreement by the payor.
 
        9.4.6.  Each of Parent and the Company agrees that the terms of Section
    7.22 and this Section 9.4 are an integral part of the transactions
    contemplated hereby. If either party fails to pay promptly the other party
    any fee due under such Sections, it shall also pay the other party's costs
    and expenses (including fees and disbursements of counsel) in connection
    with any action, including the filing of any lawsuit or other legal
 

<PAGE>
    action, taken to collect payment, together with interest on the unpaid
    amounts at the publicly announced prime rate of Fleet National Bank from the
    date such amounts were first due.

in any way to affect the validity of this Agreement or any part hereof or the
right of such party thereafter to enforce each and every such provision. No

                       FORM OF CERTIFICATE OF DESIGNATION
                    TERMS OF SPECIAL VOTING PREFERRED STOCK
 
        1.  DESIGNATION; NUMBER OF SHARES.  The class of Preferred Stock known
    as "Special Voting Preferred Stock" shall consist of one (1) share.
 
        2.  VOTING.  On all matters submitted to a vote of stockholders of the
    Corporation, the holder of the share of Special Voting Preferred Stock shall
    be entitled at any relevant date to the number of votes determined in
    accordance with a certain Voting and Exchange Trust Agreement, dated as of
                , 1999, by and among the Corporation, 1325949 Ontario Inc., a
    corporation organized and existing under the laws of the Province of Ontario
    and a wholly owned subsidiary of the Corporation, Promis Systems Corporation
    Ltd., a corporation organized and existing under the laws of Canada
    ("Promis"), and Montreal Trust Company of Canada, a trust company
    incorporated under the laws of Canada. Except as required by law or by the
    Articles of Organization of the Corporation, the holder of the share of
    Special Voting Preferred Stock and the holders of the Common Stock of the
    Corporation shall vote together as a single class in the election of
    directors and on all matters submitted to a vote of the stockholders of the
    Corporation. In the event that the Special Voting Preferred Stock is
    required by law or by the Articles of Organization of the Corporation to
    vote separately as a class or series on a proposal, the holder of the share
    of Special Voting Preferred Stock shall in addition to voting separately as
    a class or series on such proposal, also be entitled to vote with the
    holders of the Corporation's Common Stock together as a single class.
 
        3.  DIVIDENDS.  The holder of the share of Special Voting Preferred
    Stock shall not be entitled to receive any dividends.
 
        4.  LIQUIDATION.  In the event of any dissolution, liquidation or
    winding up of the affairs of the Corporation, whether voluntary or
    involuntary, the holder of the share of Special Voting Preferred Stock shall
    be entitled to be paid out of the net assets of the Corporation available
    for distribution, before any distribution or payment is made upon any stock
    of the Corporation ranking on liquidation junior to the Special Voting
    Preferred Stock, an amount equal to $1.00, subject to equitable adjustment
    in the event of stock splits, stock dividends, combinations and the like
    involving the Special Voting Preferred Stock (the "Special Voting Preferred
    Stock Liquidation Payment"). Upon any such dissolution, liquidation or
    winding up of the affairs of the Corporation, after the holder of the share
    of Special Voting Preferred Stock shall have been paid the amount to which
    it shall be entitled, the remaining net assets of the Corporation may be
    distributed to the holders of stock ranking on liquidation junior to the
    Special Voting Preferred Stock. Whenever the distribution provided for in
    this paragraph shall be paid in property other than cash, the value of such
    distribution shall be the fair market value of such property as determined
    in good faith by the Board of Directors of the Corporation. Written notice
    of such dissolution, liquidation or winding up of the affairs of the
    Corporation, stating a payment date, the amount of the Special Voting
    Preferred Liquidation Payment and the place where said Special Voting
    Preferred Stock Liquidation Payment shall be payable, shall be given by
    mail, postage prepaid, not less than 5 days prior to the payment date stated
    therein, to the holder of record of Special Voting Preferred Stock, such
    notice to be addressed to such holder at its address as shown by the records
    of the Corporation. For purposes hereof, the Common Stock shall rank on
    liquidation junior to the Special Voting Preferred Stock. A merger or
    consolidation of the Corporation with or into any other corporation or a
    sale or conveyance of all or any part of the assets of the Corporation
    (which shall not in fact result in the liquidation of the Corporation and
    the distribution of assets to stockholders) shall not be deemed to be a
    voluntary or involuntary liquidation, dissolution or winding up of the
    Corporation within the meaning of this paragraph 4.
 
        5.  REDEMPTION.  (a) The shares of Special Voting Preferred Stock shall
    be redeemed by the Corporation as described herein, at a price of $1.00,
    subject to equitable adjustment in the event of stock splits, stock
    dividends, combinations and the like involving the Special Voting Preferred
    Stock (the "Redemption Price"). Such redemption shall occur automatically
    and simultaneously, but only, upon the issuance by the Corporation of its
    Common Stock or delivery by 1325949 Ontario Inc. of the Corporation's
 

<PAGE>
    Common Stock for the last outstanding Exchangeable Share of Promis
    ("Exchangeable Share") held by a person other than the Corporation or any of
    its subsidiaries.
 
    (b) Promptly after the issuance by the Corporation of its Common Stock or
delivery by 1325949 Ontario Inc. of the Corporation's Common Stock for the last
outstanding Exchangeable Share held by a person other than the Corporation or
any of its subsidiaries, the Corporation shall give written notice (the
"Redemption Notice") by mail, postage prepaid, to the holder of record (at the
close of business on the business day next preceding the day on which the
Redemption Notice is given) of the share of Special Voting Preferred Stock
notifying such holder of the redemption and specifying the Redemption Price, the
date on which the last outstanding Exchangeable Share held by a person other
than the Corporation or any of its subsidiaries was acquired by the Corporation
or any of its subsidiaries (the "Redemption Date") and the place and date (not
to exceed 20 days from the date such notice is given) where said Redemption
Price shall be payable. The Redemption Notice shall be addressed to such holder
at the address of the holder as shown by the records of the Corporation. From
and after the close of business on the Redemption Date, unless there shall have
been a default in the payment of the Redemption Price, all rights of the holder
of the share of Special Voting Preferred Stock (including the right to vote as
provided in paragraph 2 above) shall cease with respect to such share (except
the right to receive the Redemption Price), and such share shall not thereafter
be transferred on the books of the Corporation or be deemed to be outstanding
for any purpose whatsoever. If the Corporation does not have funds legally
available for redemption of the share of Special Voting Preferred Stock on the
Redemption Date, the share of Special Voting Preferred Stock shall remain
outstanding and entitled to all rights and preferences provided herein. At any
time thereafter when the Corporation has legally available funds for the
redemption of such share of Special Voting Preferred Stock, such funds will be
used to redeem such share.
 
    (c) The share of Special Voting Preferred Stock redeemed pursuant to this
paragraph 5 or otherwise acquired by the Corporation in any manner whatsoever
shall upon any such reacquisition by the Corporation, be automatically restored
to the status of authorized but unissued shares of Preferred Stock of the
Corporation.

located at 805 Middlesex Turnpike, Billerica, Massachusetts 01821 do hereby
certify that at a meeting of the directors of the corporation held on December
7, 1998, the following vote establishing and designating a series of a class of
stock and determining the relative rights and preferences thereof was duly

                              PRI AUTOMATION, INC.

VOTED:   That, pursuant to the authority vested in the Board of Directors of
         the Corporation in accordance with the provisions of the Articles of
         Organization of the Corporation, the Board of Directors hereby
         designates and establishes [250,000] shares of its authorized but
         unissued Preferred Stock as its Series A Participating Cumulative
         Preferred Stock, $.01 par value (the "Series A Preferred Stock");
         that such Series A Preferred Stock shall have the terms set forth in
         their entirety in Exhibit A to the Rights Agreement presented to
         this meeting, and such terms be, and they hereby are, approved; and
         that the President or any Vice President and the Clerk or any
         Assistant Clerk of the Corporation be, and they hereby are,
         authorized to execute a Certificate of Vote of Directors
         Establishing a Series of a Class of Stock (the "Certificate of Vote
         of Directors") setting forth such terms in the name of the
         Corporation, and to file the Certificate of Vote of Directors with
         the Secretary of State of The Commonwealth of Massachusetts and such
         other governmental authorities as may be required by law.

<PAGE>

                                               EXHIBIT A TO THE RIGHTS AGREEMENT

                                TERMS OF SERIES A
                    PARTICIPATING CUMULATIVE PREFERRED STOCK
                                       OF
                              PRI AUTOMATION, INC.

      Section 1. Designation and Number of Shares. The shares of such series
shall be designated as "Series A Participating Cumulative Preferred Stock" (the
"Series A Preferred Stock"), $.01 par value. The number of shares initially
constituting the Series A Preferred Stock shall be [250,000]; provided, however,
that, if more than a total of [250,000] shares of Series A Preferred Stock shall
be issuable upon the exercise of "Rights") issued pursuant to the Rights
Agreement dated as of December 7, 1998, between the Corporation and State Street
Bank and Trust Company, as Agent (the "Rights Agreement"), the Board of
Directors of the Corporation, pursuant to Section 26 of Chapter 156B of the
Massachusetts General Laws, shall direct by resolution or resolutions that a
certificate be properly executed, acknowledged, filed and recorded, in
accordance with the provisions of said Section 26 thereof, providing for the
total number of shares of Series A Preferred Stock authorized to be issued to be
increased (to the extent that the Articles of Organization then permits) to the
largest number of whole shares (rounded up to the nearest whole number) issuable
upon exercise of such Rights.

      Section 2. Dividends or Distributions.

            (a) Subject to the prior and superior rights of the holders of
shares of any other series of Preferred Stock or other class of capital stock of
the Corporation ranking prior and superior to the shares of Series A Preferred
Stock with respect to dividends, the holders of shares of the Series A Preferred
Stock shall be entitled to receive, when, as and if declared by the Board of
Directors, out of the assets of the Corporation legally available therefor, (1)
quarterly dividends payable in cash on the last day of each fiscal quarter in
each year, or such other dates as the Board of Directors of the Corporation
shall approve (each such date being referred to herein as a "Quarterly Dividend
Payment Date"), commencing on the first Quarterly Dividend Payment Date after
the first issuance of a share or a fraction of a share of Series A Preferred
Stock, in the amount of $1.00 per whole share (rounded to the nearest cent) less
the amount of all cash dividends declared on the Series A Preferred Stock
pursuant to the following clause (2) since the immediately preceding Quarterly
Dividend Payment Date or, with respect to the first Quarterly Dividend Payment
Date, since the first issuance of any share or fraction of a share of Series A
Preferred Stock (the total of which shall not, in any event, be less than zero)
and (2) dividends payable in cash on the payment date for each cash dividend
declared on the Common Stock in an amount per whole share (rounded to the
nearest cent) equal to the Formula Number (as hereinafter defined) then in
effect times the cash dividends then to be paid on each share of Common Stock.
In addition, if the Corporation shall pay any dividend or make any distribution
on the Common Stock payable in assets,
<PAGE>

securities or other forms of non-cash consideration (other than dividends or
distributions solely in shares of Common Stock), then, in each such case, the
Corporation shall simultaneously pay or make on each outstanding whole share of
Series A Preferred Stock a dividend or distribution in like kind equal to the
Formula Number then in effect times such dividend or distribution on each share
of the Common Stock. As used herein, the "Formula Number" shall be 100;
provided, however, that if at any time after December 7, 1998 the Corporation
shall (i) declare or pay any dividend on the Common Stock payable in shares of
Common Stock or make any distribution on the Common Stock in shares of Common
Stock, (ii) subdivide (by a stock split or otherwise) the outstanding shares of
Common Stock into a larger number of shares of Common Stock or (iii) combine (by
a reverse stock split or otherwise) the outstanding shares of Common Stock into
a smaller number of shares of Common Stock, then in each such event the Formula
Number shall be adjusted to a number determined by multiplying the Formula
Number in effect immediately prior to such event by a fraction, the numerator of
which is the number of shares of Common Stock that are outstanding immediately
after such event and the denominator of which is the number of shares of Common
Stock that are outstanding immediately prior to such event (and rounding the
result to the nearest whole number); and provided further, that, if at any time
after December 7, 1998, the Corporation shall issue any shares of its capital
stock in a merger, reclassification, or change of the outstanding shares of
Common Stock, then in each such event the Formula Number shall be appropriately
adjusted to reflect such merger, reclassification or change so that each share
of Series A Preferred Stock continues to be the economic equivalent of a Formula
Number of shares of Common Stock prior to such merger, reclassification or
change.

            (b) The Corporation shall declare a dividend or distribution on the
Series A Preferred Stock as provided in Section 2(a) immediately prior to or at
the same time it declares a dividend or distribution on the Common Stock (other
than a dividend or distribution solely in shares of Common Stock); provided,
however, that, in the event no dividend or distribution (other than a dividend
or distribution in shares of Common Stock) shall have been declared on the
Common Stock during the period between any Quarterly Dividend Payment Date and
the next subsequent Quarterly Dividend Payment Date, a dividend of $1.00 per
whole share on the Series A Preferred Stock shall nevertheless be payable on
such subsequent Quarterly Dividend Payment Date. The Board of Directors may fix
a record date for the determination of holders of shares of Series A Preferred
Stock entitled to receive a dividend or distribution declared thereon, which
record date shall be the same as the record date for any corresponding dividend
or distribution on the Common Stock.

            (c) Dividends shall begin to accrue and be cumulative on outstanding
shares of Series A Preferred Stock from and after the Quarterly Dividend Payment
Date next preceding the date of original issue of such shares of Series A
Preferred Stock; provided, however, that dividends on such shares which are
originally issued after the record date for the determination of holders of
shares of Series A Preferred Stock entitled to receive a quarterly dividend and
on or prior to the next succeeding Quarterly Dividend Payment Date shall begin
to accrue and be
<PAGE>

cumulative from and after such Quarterly Dividend Payment Date. Notwithstanding
the foregoing, dividends on shares of Series A Preferred Stock which are
originally issued prior to the record date for the determination of holders of
shares of Series A Preferred Stock entitled to receive a quarterly dividend on
the first Quarterly Dividend Payment Date shall be calculated as if cumulative
from and after the last day of the fiscal quarter next preceding the date of
original issuance of such shares. Accrued but unpaid dividends shall not bear
interest. Dividends paid on the shares of Series A Preferred Stock in an amount
less than the total amount of such dividends at the time accrued and payable on
such shares shall be allocated pro rata on a share-by-share basis among all such
shares at the time outstanding.

            (d) So long as any shares of the Series A Preferred Stock are
outstanding, no dividends or other distributions shall be declared, paid or
distributed, or set aside for payment or distribution, on the Common Stock
unless, in each case, the dividend required by this Section 2 to be declared on
the Series A Preferred Stock shall have been declared.

            (e) The holders of the shares of Series A Preferred Stock shall not
be entitled to receive any dividends or other distributions except as provided
herein.

      Section 3. Voting Rights. The holders of shares of Series A Preferred
Stock shall have the following voting rights:

            (a) Each holder of Series A Preferred Stock shall be entitled to a
number of votes equal to the Formula Number then in effect for each share of
Series A Preferred Stock held of record on each matter on which holders of the
Common Stock or stockholders generally are entitled to vote, multiplied by the
maximum number of votes per share which any holder of the Common Stock or
stockholders generally then have with respect to such matter (assuming any
holding period or other requirement to vote a greater number of shares is
satisfied).

            (b) Except as otherwise provided herein or by applicable law, the
holders of shares of Series A Preferred Stock and the holders of shares of
Common Stock shall vote together as one class for the election of directors of
the Corporation and on all other matters submitted to a vote of stockholders of
the Corporation.

            (c) If, at the time of any annual meeting of stockholders for the
election of directors, the equivalent of six quarterly dividends (whether or not
consecutive) payable on any share or shares of Series A Preferred Stock are in
default, the number of directors constituting the Board of Directors of the
Corporation shall be increased by two. In addition to voting together with the
holders of Common Stock for the election of other directors of the Corporation,
the holders of record of the Series A Preferred Stock, voting separately as a
class to the exclusion of the holders of Common Stock, shall be entitled at said
meeting of stockholders (and at each subsequent annual meeting of stockholders),
unless all dividends in arrears have been paid or declared and set apart for
payment prior thereto, to vote for the election of two directors of the
Corporation, the holders of

<PAGE>

any Series A Preferred Stock being entitled to cast a number of votes per share
of Series A Preferred Stock equal to the Formula Number. Until the default in
payments of all dividends which permitted the election of said directors shall
cease to exist, any director who shall have been so elected pursuant to the next
preceding sentence may be removed at any time, either with or without cause,
only by the affirmative vote of the holders of the shares of Series A Preferred
Stock at the time entitled to cast a majority of the votes entitled to be cast
for the election of any such director at a special meeting of such holders
called for that purpose, and any vacancy thereby created may be filled by the
vote of such holders. If and when such default shall cease to exist, the holders
of the Series A Preferred Stock shall be divested of the foregoing special
voting rights, subject to revesting in the event of each and every subsequent
like default in payments of dividends. Upon the termination of the foregoing
special voting rights, the terms of office of all persons who may have been
elected directors pursuant to said special voting rights shall forthwith
terminate, and the number of directors constituting the Board of Directors shall
be reduced by two. The voting rights granted by this Section 3(c) shall be in
addition to any other voting rights granted to the holders of the Series A
Preferred Stock in this Section 3.

            (d) Except as provided herein, in Section 11 or by applicable law,
holders of Series A Preferred Stock shall have no special voting rights and
their consent shall not be required (except to the extent they are entitled to
vote with holders of Common Stock as set forth herein) for authorizing or taking
any corporate action.

      Section 4. Certain Restrictions.

            (a) Whenever quarterly dividends or other dividends or distributions
payable on the Series A Preferred Stock as provided in Section 2 are in arrears,
thereafter and until all accrued and unpaid dividends and distributions, whether
or not declared, on shares of Series A Preferred Stock outstanding shall have
been paid in full, the Corporation shall not

                  (i) declare or pay dividends on, make any other distributions
      on, or redeem or purchase or otherwise acquire for consideration any
      shares of stock ranking junior (either as to dividends or upon
      liquidation, dissolution or winding up) to the Series A Preferred Stock;

                  (ii) declare or pay dividends on or make any other
      distributions on any shares of stock ranking on a parity (either as to
      dividends or upon liquidation, dissolution or winding up) with the Series
      A Preferred Stock, except dividends paid ratably on the Series A Preferred
      Stock and all such parity stock on which dividends are payable or in
      arrears in proportion to the total amounts to which the holders of all
      such shares are then entitled;

                  (iii) redeem or purchase or otherwise acquire for
       consideration shares of any stock ranking on a parity (either as to
       dividends or upon liquidation, dissolution or winding up) with the Series
       A Preferred
<PAGE>

       Stock; provided that the Corporation may at any time redeem, purchase or
       otherwise acquire shares of any such parity stock in exchange for shares
       of any stock of the Corporation ranking junior (either as to dividends or
       upon dissolution, liquidation or winding up) to the Series A Preferred
       Stock; or

                  (iv) purchase or otherwise acquire for consideration any
      shares of Series A Preferred Stock, or any shares of stock ranking on a
      parity with the Series A Preferred Stock, except in accordance with a
      purchase offer made in writing or by publication (as determined by the
      Board of Directors) to all holders of such shares upon such terms as the
      Board of Directors, after consideration of the respective annual dividend
      rates and other relative rights and preferences of the respective series
      and classes, shall determine in good faith will result in fair and
      equitable treatment among the respective series or classes.

            (b) The Corporation shall not permit any subsidiary of the
Corporation to purchase or otherwise acquire for consideration any shares of
stock of the Corporation unless the Corporation could, under paragraph (a) of
this Section 4, purchase or otherwise acquire such shares at such time and in
such manner.

      Section 5. Liquidation Rights. Upon the liquidation, dissolution or
winding up of the Corporation, whether voluntary or involuntary, no distribution
shall be made (1) to the holders of shares of stock ranking junior (either as to
dividends or upon liquidation, dissolution or winding up) to the Series A
Preferred Stock unless, prior thereto, the holders of shares of Series A
Preferred Stock shall have received an amount equal to the accrued and unpaid
dividends and distributions thereon, whether or not declared, to the date of
such payment, plus an amount equal to the greater of (x) $1.00 per whole share
or (y) an aggregate amount per share equal to the Formula Number then in effect
times the aggregate amount to be distributed per share to holders of Common
Stock or (2) to the holders of stock ranking on a parity (either as to dividends
or upon liquidation, dissolution or winding up) with the Series A Preferred
Stock, except distributions made ratably on the Series A Preferred Stock and all
other such parity stock in proportion to the total amounts to which the holders
of all such shares are entitled upon such liquidation, dissolution or winding
up.

      Section 6. Consolidation, Merger, etc. In case the Corporation shall enter
into any consolidation, merger, combination or other transaction in which the
shares of Common Stock are exchanged for or changed into other stock or
securities, cash or any other property, then in any such case the then
outstanding shares of Series A Preferred Stock shall at the same time be
similarly exchanged or changed into an amount per share equal to the Formula
Number then in effect times the aggregate amount of stock, securities, cash or
any other property (payable in kind), as the case may be, into which or for
which each share of Common Stock is exchanged or changed. In the event both this
Section 6 and Section 2 appear to apply to a transaction, this Section 6 will
control.

<PAGE>

      Section 7. No Redemption; No Sinking Fund.

            (a) The shares of Series A Preferred Stock shall not be subject to
redemption by the Corporation or at the option of any holder of Series A
Preferred Stock; provided, however, that the Corporation may purchase or
otherwise acquire outstanding shares of Series A Preferred Stock in the open
market or by offer to any holder or holders of shares of Series A Preferred
Stock.

            (b) The shares of Series A Preferred Stock shall not be subject to
or entitled to the operation of a retirement or sinking fund.

      Section 8. Ranking. The Series A Preferred Stock shall rank junior to all
other series of Preferred Stock of the Corporation, unless the Board of
Directors shall specifically determine otherwise in fixing the powers,
preferences and relative, participating, optional and other special rights of
the shares of such series and the qualifications, limitations and restrictions
thereof.

      Section 9. Fractional Shares. The Series A Preferred Stock shall be
issuable upon exercise of the Rights issued pursuant to the Rights Agreement in
whole shares or in any fraction of a share that is one one-hundredth (1/100th)
of a share or any integral multiple of such fraction which shall entitle the
holder, in proportion to such holder's fractional shares, to receive dividends,
exercise voting rights, participate in distributions and to have the benefit of
all other rights of holders of Series A Preferred Stock. In lieu of fractional
shares, the Corporation, prior to the first issuance of a share or a fraction of
a share of Series A Preferred Stock, may elect (1) to make a cash payment as
provided in the Rights Agreement for fractions of a share other than one
one-hundredth (1/100th) of a share or any integral multiple thereof or (2) to
issue depository receipts evidencing such authorized fraction of a share of
Series A Preferred Stock pursuant to an appropriate agreement between the
Corporation and a depository selected by the Corporation; provided that such
agreement shall provide that the holders of such depository receipts shall have
all the rights, privileges and preferences to which they are entitled as holders
of the Series A Preferred Stock.

      Section 10. Reacquired Shares. Any shares of Series A Preferred Stock
purchased or otherwise acquired by the Corporation in any manner whatsoever
shall be retired and canceled promptly after the acquisition thereof. All such
shares shall upon their cancellation become authorized but unissued shares of
Preferred Stock, without designation as to series until such shares are once
more designated as part of a particular series by the Board of Directors
pursuant to the provisions of the Articles of Organization.

<PAGE>

      Section 11. Amendment. None of the powers, preferences and relative,
participating, optional and other special rights of the Series A Preferred Stock
as provided herein or in the Articles of Organization shall be amended in any
manner which would alter or change the powers, preferences, rights or privileges
of the holders of Series A Preferred Stock so as to affect them adversely
without the affirmative vote of the holders of at least 66-2/3% of the
outstanding shares of Series A Preferred Stock, voting as a separate class;
provided, however, that no such amendment approved by the holders of at least
66-2/3% of the outstanding shares of Series A Preferred Stock shall be deemed to
apply to the powers, preferences, rights or privileges of any holder of shares
of Series A Preferred Stock originally issued upon exercise of the Rights after
the time of such approval without the approval of such holder.

Ladies and Gentlemen:

    We are familiar with the Registration Statement on Form S-3 (the "S-3 
Registration Statement") filed today by PRI Automation, Inc., a Massachusetts 
corporation (the "Company"), with the Securities and Exchange Commission 
under the Securities Act of 1933, as amended. The S-3 Registration Statement 
relates to the proposed issuance and sale by the Company of up to 2,490,516 
shares (the "Shares") of its Common Stock, $0.01 par value per share.

    In arriving at the opinions expressed below, we have examined and relied 
on the following documents: (a) the Restated Articles of Organization of the 
Company, as amended; (b) the Amended and Restated By-Laws of the Company; and 
(c) the records of meetings and consents of the Board of Directors and 
stockholders of the Company provided to us by the Company. In addition, we 
have examined and relied on the originals or copies certified or otherwise 
identified to our satisfaction of all such corporate records of the Company 
and such other instruments and other certificates of public officials, 
officers and representatives of the Company and such other persons, and we 
have made such investigations of law, as we have deemed appropriate as a 
basis for the opinions expressed below.

    Based upon the foregoing, it is our opinion that:

    1.    The Company has taken all necessary corporate action required to 
authorize the issuance and sale of the Shares; and

    2.    The Shares, when issued and delivered as contemplated in the S-3 
Registration Statement, will be validly and legally issued and fully paid and 
non-assessable.

    We hereby consent to the filing of this opinion as an exhibit to the S-3 
Registration Statement and to the reference to our firm under the heading 
"Legal Matters" in the S-3 Registration Statement.


                                     Very Truly Yours,

Ladies and Gentlemen:

     Reference is made to the information set forth under the heading "Income 
Tax Considerations -- Canadian Federal Income Tax Considerations to Holders 
of Exchangeable Shares" (the "Canadian Tax Summary") contained in the 
Registration Statement on Form S-3 (the "Registration Statement"), filed by

Commission (the "SEC") on December 24, 1998, for the purpose of registering 
2,490,516 shares of common stock, par value $.01 per share, of the Company.

     We have aided in the preparation of the Registration Statement, 
including in particular the Canadian Tax Summary. We hereby confirm that, 
subject to the assumptions, limitations and qualifications set out in the 
Canadian Tax Summary, in all material respects, the Canadian Tax Summary is a 
fair and accurate summary of the matters addressed therein, based upon the 
current provisions of the Income Tax Act (Canada), the regulations 
thereunder, all proposed amendments to such Act and such regulations publicly 
released by the Minister of Finance (Canada) prior to the date hereof, the 
current provisions of the Canada-United States Income Tax Convention (1980), 
as amended, and our understanding of the current administrative practices of 
Revenue Canada. Our opinion is not binding on Revenue Canada or a court of 
law, and no assurance can be given that Revenue Canada will not take contrary 
positions and that a court may agree with such contrary positions. In 
addition, no assurance can be given that legislative or administrative action 
or judicial decisions that differ from our opinion will not be forthcoming. 
Any such differences could be retroactive to transactions or business 
operations prior to such action or decisions. We can give no assurance that, 
after such change, our opinion would not be different. We undertake no 
responsibility to update or supplement our opinion following the effective 
date of the Registration Statement.

     This opinion is furnished to you solely for your benefit in connection 
with the filing of the Registration Statement and is not to be used, 
circulated, quoted or otherwise referred to for any other purpose or relied 
upon by any other person for any purpose without our prior written consent. 
We also consent to the use of our name in the Canadian Tax Summary and to the 
filing of this opinion with the SEC as an exhibit to the Registration 
Statement. In giving such consent, we do not thereby admit that we are in the 
category of persons whose consent is required under Section 7 of the 
Securities Act of 1933, as amended, or the rules and regulations of the SEC 
promulgated thereunder.

                                   ARTICLE 2
                                  ARRANGEMENT
 
    Section 2.1  ARRANGEMENT.  At the Effective Time on the Effective Date, the
following reorganization of capital and other transactions shall occur and shall
be deemed to occur in the following order without any further act or formality
and shall become effective at, and be binding at and after, the Effective Time
on (i) PRI and Subco; (ii) Promis; (iii) all holders of Promis Common Shares;
(iv) all holders of Exchangeable Shares; and (v) all holders of Options and
Warrants:
 
    (a) The Articles of Incorporation of Promis shall be amended to create and
       authorize an unlimited number of Exchangeable Shares and one Class X
       Preferred Share.
 
    (b) Promis shall issue to Subco one Class X Preferred Share in consideration
       for the payment by Subco to Promis of an amount equal to the fair market
       value, as determined by the board of directors of Promis, of one Promis
       Common Share. No certificate shall be issued in respect of the Class X
       Preferred Share.
 
    (c) Each Promis Common Share (other than Promis Common Shares held by
       holders who have exercised their rights of dissent in accordance with
       Section 3.1 hereof and who are ultimately entitled to be paid the fair
       value for such shares and other than Promis Common Shares held by PRI or
       any Subsidiary thereof) will be exchanged at the Exchange Ratio for a
       number of Exchangeable Shares, and each such holder thereof will receive
       a whole number of Exchangeable Shares resulting therefrom. In lieu of
       fractional Exchangeable Shares, each such holder who otherwise would be
       entitled to receive a fraction of an Exchangeable Share on the exchange
       shall be paid by Promis an amount determined as set forth in Section 4.3.
 
    (d) Upon the exchange referred to in subsection (c) above, each such holder
       of a Promis Common Share shall cease to be such a holder, shall have his
       name removed from the register of holders of Promis Common Shares and
       shall become a holder of the number of fully paid Exchangeable Shares to
       which he is entitled as a result of the exchange referred to in
       subsection (c), and such holder's name shall be added to the register of
       holders of Exchangeable Shares accordingly.
 
    (e) The aggregate stated capital of the Exchangeable Shares will be equal to
       the aggregate stated capital immediately prior to the Effective Date of
       the Promis Common Shares which are exchanged pursuant to such subsection
       2.1(c) above, thereby excluding the stated capital attributable to the
       fractional shares for which payment is made as contemplated in subsection
       (c) above.
 
    (f) The Articles of Incorporation of Promis shall be amended to reduce the
       number of authorized Promis Common Shares to one and the rights,
       privileges, restrictions and conditions attaching to the Promis Common
       Share shall be changed and restated as set forth in Appendix A.
 
    (g) The one outstanding Class X Preferred Share will be exchanged for one
       fully-paid and non-assessable Promis Common Share and the holder thereof
       shall cease to be a holder of the Class X Preferred Share, shall have its
       name removed from the register of holders of the Class X Preferred Share
       and shall become a holder of the Promis Common Share to which it is
       entitled as a result of the exchange
 
                                      
<PAGE>
       referred to in this subsection (g), and such holder's name shall be added
       to the register as holder of the Promis Common Share accordingly.
 
    (h) The stated capital of the one Promis Common Share shall be equal to the
       stated capital of the one Class X Preferred Share immediately prior to
       the exchange contemplated in subsection (g).
 
    (i) The Articles of Incorporation of Promis shall be amended to delete the
       Class X Preferred Share and the authorized but unissued Class of
       Preferred Shares in the capital of Promis from the authorized share
       capital so that, after giving effect to the foregoing provisions of this
       section 2.1, the authorized capital of Promis shall consist of an
       unlimited number of Exchangeable Shares having the rights, privileges,
       restrictions and conditions set forth in Appendix A hereto and one Common
       Share having the rights, privileges, restrictions and conditions set
       forth in Appendix A hereto.
 
    (j) Each of the then outstanding Options and Warrants will, without any
       further action on the part of any Optionholder or Warrantholder, be
       converted into an option or warrant, as the case may be, to purchase the
       number of shares of PRI Common Stock equal to the number determined by
       multiplying the number of Promis Common Shares subject to such Option or
       Warrant at the Effective Time by the Exchange Ratio, at an exercise price
       per share of PRI Common Stock equal to the exercise price per share of
       such Option or Warrant immediately prior to the Effective Time divided by
       the Exchange Ratio and converted from Canadian dollars to U.S. dollars at
       the noon spot exchange rate announced by the Bank of Canada on the third
       Business Day immediately preceding the Effective Date. If the foregoing
       calculation results in an exchanged Option or Warrant being exercisable
       for a fraction of a share of PRI Common Stock, then the number of shares
       of PRI Common Stock subject to such Option or Warrant will be rounded
       down to the nearest whole number of shares, and the exercise price per
       whole share of PRI Common Stock will be as determined above. The Promis
       Options or Warrants as so converted will (without further action on the
       part of the Optionholders or Warrants as the case may be) be further
       modified as necessary to effect such conversion; provided, however, the
       term, exercisability, vesting schedule, and all other terms and
       conditions of the Options or Warrants will otherwise be unchanged by the
       provisions of this paragraph (j) and shall operate in accordance with
       their terms. The obligations of Promis under the Promis Options or
       Warrants as so converted shall be assumed by PRI and PRI shall be
       substituted for Promis as the sponsor of the Promis Option Plan.
 
    (k) All rights outstanding under the Shareholders Rights Plan Agreement
       between Promis and Montreal Trust Company of Canada dated as of January
       27, 1997 (the "Rights Plan") immediately prior to the Effective Date
       shall, at the Effective Time, be redeemed and cancelled, all on the terms
       and with the effects and results contained in the Rights Plan, and the
       Rights Plan shall be terminated.
 
                                   ARTICLE 3
                               RIGHTS OF DISSENT
 
    Section 3.1  RIGHTS OF DISSENT.  Holders of Promis Common Shares may
exercise rights of dissent with respect to such shares pursuant to and in the
manner set forth in section 190 of the CBCA and this Section 3.1 (the "Dissent
Procedures") in connection with the Arrangement, provided that, notwithstanding
subsection 190(5) of the CBCA, the written objection to the Arrangement
Resolution referred to in subsection 190(5) of the CBCA must be received by
Promis not later than 5:00 p.m. (Toronto time) on the Business Day preceding the
Meeting. Holders of Promis Common Shares who duly exercise such rights of
dissent and who:
 
    (a) are ultimately entitled to be paid fair value for their Promis Common
       Shares shall be deemed to have transferred such Promis Common Shares to
       Promis for cancellation on the Effective Date at the Effective Time; or
 
    (b) are ultimately not entitled, for any reason, to be paid the fair value
       for their Promis Common Shares shall be deemed to have participated in
       the Arrangement on the same basis as any non dissenting holder of Promis
       Common Shares,
 
                                      
<PAGE>
but in no case shall Promis or any other person be required to recognize such
holders as holders of Promis Common Shares on and after the Effective Time, and
the names of such persons shall be deleted from the registers of holders of
Promis Common Shares as at the Effective Time.
 
                                   ARTICLE 4
                       CERTIFICATES AND FRACTIONAL SHARES
 
    Section 4.1  ISSUANCE OF CERTIFICATES REPRESENTING EXCHANGEABLE SHARES.  At
or promptly after the Effective Time, Promis shall deposit with the Depositary,
for the benefit of the holders of Promis Common Shares exchanged pursuant to
subsection 2.1(c), certificates representing the Exchangeable Shares issued
pursuant to subsection 2.1(c) upon the exchange. Upon surrender to the
Depositary of a certificate which immediately prior to the Effective Time
represented outstanding Promis Common Shares together with such other documents
and instruments as would have been required to effect the transfer of the shares
formerly represented by such certificate under the CBCA and the by-laws of
Promis and such additional documents and instruments as the Depositary may
reasonably require, the holder of such surrendered certificate shall be entitled
to receive in exchange therefor, and the Depositary shall deliver to such
holder, a certificate representing that number (rounded down to the nearest
whole number) of Exchangeable Shares which such holder has the right to receive
(together with any dividends or distributions with respect thereto pursuant to
Section 4.2 and any cash in lieu of fractional Exchangeable Shares pursuant to
Section 4.3), and the certificate so surrendered shall forthwith be cancelled.
In the event of a transfer of ownership of Promis Common Shares which is not
registered in the transfer records of Promis, a certificate representing the
proper number of Exchangeable Shares may be issued to a transferee if the
certificate representing such Promis Common Shares is presented to the
Depositary, accompanied by all documents required to evidence and effect such
transfer. Until surrendered as contemplated by this Section 4.1, each
certificate which immediately prior to the Effective Time represented
outstanding Promis Common Shares, shall be deemed at any time after the
Effective Time, but subject to Section 4.5, to represent only the right to
receive upon such surrender (a) the certificate representing Exchangeable Shares
as contemplated by this Section 4.1, (b) a cash payment in lieu of any
fractional Exchangeable Shares as contemplated by Section 4.3 and (c) any
dividends or distributions with a record date after the Effective Time
theretofore paid or payable with respect to Exchangeable Shares as contemplated
by Section 4.2.
 
    Section 4.2  DISTRIBUTIONS WITH RESPECT TO UNSURRENDERED CERTIFICATES.  No
dividends or other distributions declared or made after the Effective Time with
respect to Exchangeable Shares with a record date after the Effective Time shall
be paid to the holder of any formerly outstanding Promis Common Shares which
were exchanged pursuant to Section 2.1, and no cash payment in lieu of
fractional shares shall be paid to any such holder pursuant to Section 4.3,
unless and until the certificate representing such shares shall be surrendered
in accordance with Section 4.1. Subject to applicable law and to Section 4.5, at
the time of such surrender of any such certificate (or, in the case of clause
(c) below, at the appropriate payment date), there shall be paid to the holder
of the Exchangeable Shares resulting from exchange, in all cases without
interest, (a) the amount of any cash payable in lieu of a fractional
Exchangeable Share to which such holder is entitled pursuant to Section 4.3, (b)
the amount of dividends or other distributions with a record date after the
Effective Time theretofore paid with respect to such Exchangeable Shares, and
(c) the amount of dividends or other distributions with a record date after the
Effective Time but prior to surrender and a payment date subsequent to surrender
payable with respect to such Exchangeable Shares.
 
    Section 4.3  NO FRACTIONAL SHARES.  No certificates or scrip representing
fractional Exchangeable Shares shall be issued upon the surrender for exchange
of certificates pursuant to Section 4.1, and such fractional interests shall not
entitle the owner thereof to vote or to possess or exercise any rights as a
security holder of Promis. In lieu of any such fractional interests, each person
entitled thereto will receive an amount of cash (rounded to the nearest whole
cent), without interest, equal to the product of (a) such fractional interest,
multiplied by (b) the Average Closing Price, such amount to be provided to the
Depositary by Promis upon request.
 
    Section 4.4  LOST CERTIFICATES.  If any certificate which immediately prior
to the Effective Time represented outstanding Promis Common Shares which were
exchanged pursuant to Section 2.1 has been lost,
 
                                      
<PAGE>
stolen or destroyed, upon the making of an affidavit of that fact by the person
claiming such certificate to be lost, stolen or destroyed, the Depositary will
issue in exchange for such lost, stolen or destroyed certificate, certificates
representing Exchangeable Shares (and any dividends or distributions with
respect thereto and any cash pursuant to Section 4.3) deliverable in respect
thereof as determined in accordance with Section 2.1. When authorizing such
payment in exchange for any lost, stolen or destroyed certificate, the person to
whom certificates representing Exchangeable Shares are to be issued shall, as a
condition precedent to the issuance thereof, give a bond satisfactory to Promis,
PRI, Subco and the Transfer Agent, as the case may be, in such sum as Promis may
direct, or otherwise indemnify Promis, PRI, Subco and the Transfer Agent in a
manner satisfactory to Promis, PRI, Subco and the Transfer Agent against any
claim that may be made against Promis, PRI, Subco or the Transfer Agent with
respect to the certificate alleged to have been lost, stolen or destroyed.
 
    Section 4.5  EXTINGUISHMENT OF RIGHTS.  Any certificate which immediately
prior to the Effective Time represented outstanding Promis Common Shares which
were exchanged pursuant to Section 2.1 and has not been deposited, with all
other instruments required by Section 4.1, on or prior to the tenth anniversary
of the Effective Date shall cease to represent a claim or interest of any kind
or nature as a shareholder of Promis. On such date, the Exchangeable Shares to
which the former registered holder of the certificate referred to in the
preceding sentence was ultimately entitled shall be deemed to have been
surrendered to Promis, together with all entitlements to dividends,
distributions and interest thereon held for such former registered holder, for
no consideration and shall thereupon be cancelled and the name of the former
registered holder shall be removed from the register of holders of such shares.
 
    Section 4.6  WITHHOLDING RIGHTS.  Promis, Subco and the Depositary shall be
entitled to deduct and withhold from any dividend or consideration otherwise
payable to any holder of Promis Common Shares or Exchangeable Shares such
amounts as Promis, Subco or the Depositary is required or permitted to deduct
and withhold with respect to such payment under the Income Tax Act (Canada), the
United States Internal Revenue Code of 1986 or any provision of provincial,
state, local or foreign tax law, in each case, as amended. To the extent that
amounts are so withheld, such withheld amounts shall be treated for all purposes
hereof as having been paid to the holder of the shares in respect of which such
deduction and withholding was made, provided that such withheld amounts are
actually remitted to the appropriate taxing authority. To the extent that the
amount so required or permitted to be deducted or withheld from any payment to a
holder exceeds the cash portion of the consideration otherwise payable to the
holder, Promis, Subco and the Depositary are hereby authorized to sell or
otherwise dispose of such portion of the consideration as is necessary to
provide sufficient funds to Promis, Subco or the Depositary, as the case may be,
to enable it to comply with such deduction or withholding requirement and
Promis, Subco or the Depositary shall notify the holder thereof and remit any
unapplied balance of the net proceeds of such sale.
 
                                   ARTICLE 5
                       CERTAIN RIGHTS AND OBLIGATIONS OF
                      SUBCO TO ACQUIRE EXCHANGEABLE SHARES
 
    Section 5.1  SUBCO LIQUIDATION CALL RIGHT.
 
    (a) Subco shall have the overriding right (the "LIQUIDATION CALL RIGHT"), in
       the event of and notwithstanding the proposed liquidation, dissolution or
       winding-up of Promis as referred to in Article 5 of the Exchangeable
       Share Provisions, to purchase from all but not less than all of the
       holders (other than PRI and any Subsidiary thereof) of Exchangeable
       Shares on the Liquidation Date all but not less than all of the
       Exchangeable Shares held by such holders on payment by Subco to each
       holder of the Exchangeable Share Price applicable on the last Business
       Day prior to the Liquidation Date (the "LIQUIDATION CALL PURCHASE
       PRICE"). In the event of the exercise of the Liquidation Call Right by
       Subco, each holder shall be obligated to sell all the Exchangeable Shares
       held by the holder to Subco on the Liquidation Date on payment by Subco
       to the holder of the Liquidation Call Purchase Price for each such share.
 
    (b) To exercise the Liquidation Call Right, Subco must notify the Transfer
       Agent in writing, as agent for the holders of Exchangeable Shares, and
       Promis of Subco's intention to exercise such right at least 55 days
       before the Liquidation Date in the case of a voluntary liquidation,
       dissolution or winding-up of
 
                                      
<PAGE>
       Promis and at least five Business Days before the Liquidation Date in the
       case of an involuntary liquidation, dissolution or winding-up of Promis.
       Subco shall also notify the Transfer Agent accordingly if it does not
       intend to exercise the Liquidation Call Right. The Transfer Agent will
       notify the holders of Exchangeable Shares as to whether or not Subco has
       exercised the Liquidation Call Right forthwith after the expiry of the
       date by which the same may be exercised by Subco. If Subco exercises the
       Liquidation Call Right, on the Liquidation Date Subco will purchase and
       the holders will sell all of the Exchangeable Shares then outstanding for
       a price per share equal to the Liquidation Call Purchase Price.
 
    (c) For the purposes of completing the purchase of the Exchangeable Shares
       pursuant to the Liquidation Call Right, Subco shall deposit with the
       Transfer Agent, on or before the Liquidation Date, the Exchangeable Share
       Consideration representing the total Liquidation Call Purchase Price.
       Provided that such Exchangeable Share Consideration has been so deposited
       with the Transfer Agent, on and after the Liquidation Date the right of
       each holder of Exchangeable Shares will be limited to receiving such
       holder's proportionate part of the total Liquidation Call Purchase Price
       payable by Subco without interest upon presentation and surrender by the
       holder of certificates representing the Exchangeable Shares held by such
       holder and the holder shall on and after the Liquidation Date be
       considered and deemed for all purposes to be the holder of the PRI Common
       Stock delivered to it. Upon surrender to the Transfer Agent of a
       certificate or certificates representing Exchangeable Shares, together
       with such other documents and instruments as may be required to effect a
       transfer of Exchangeable Shares under the CBCA and the by-laws of Promis
       and such additional documents and instruments as the Transfer Agent may
       reasonably require, the holder of such surrendered certificate or
       certificates shall be entitled to receive in exchange therefor, and the
       Transfer Agent on behalf of Subco shall deliver to such holder, the
       Exchangeable Share Consideration to which the holder is entitled. If
       Subco does not exercise the Liquidation Call Right in the manner
       described above, on the Liquidation Date the holders of the Exchangeable
       Shares will be entitled to receive in exchange therefor the liquidation
       price otherwise payable by Promis in connection with the liquidation,
       dissolution or winding-up of Promis pursuant to Article 5 of the
       Exchangeable Share Provisions. Notwithstanding the foregoing, until such
       Exchangeable Share Consideration is delivered to the holder, the holder
       shall be deemed to still be a holder of Exchangeable Shares for purposes
       of all voting rights with respect thereto under the Voting and Exchange
       Trust Agreement.
 
    Section 5.2  SUBCO REDEMPTION CALL RIGHT.
 
    (a) Subco shall have the overriding right (the "REDEMPTION CALL RIGHT"),
       notwithstanding the proposed redemption of the Exchangeable Shares by
       Promis pursuant to Article 7 of the Exchangeable Share Provisions, to
       purchase from all but not less than all of the holders (other than PRI or
       any Subsidiary thereof) of Exchangeable Shares on the Automatic
       Redemption Date all but not less than all of the Exchangeable Shares held
       by each such holder on payment by Subco to the holder of the Exchangeable
       Share Price applicable on the last Business Day prior to the Automatic
       Redemption Date (the "REDEMPTION CALL PURCHASE PRICE"). In the event of
       the exercise of the Redemption Call Right by Subco, each holder shall be
       obligated to sell all the Exchangeable Shares held by the holder to Subco
       on the Automatic Redemption Date on payment by Subco to the holder of the
       Redemption Call Purchase Price for each such share.
 
    (b) To exercise the Redemption Call Right, Subco must notify the Transfer
       Agent in writing, as agent for the holders of Exchangeable Shares, and
       Promis of Subco's intention to exercise such right not later than the
       date by which Promis is required to give notice of the Automatic
       Redemption Date. If Subco exercises the Redemption Call Right, on the
       Automatic Redemption Date Subco will purchase and the holders will sell
       all of the Exchangeable Shares then outstanding for a price per share
       equal to the Redemption Call Purchase Price.
 
    (c) For the purposes of completing the purchase of the Exchangeable Shares
       pursuant to the Redemption Call Right, Subco shall deposit with the
       Transfer Agent, on or before the Automatic Redemption Date, the
       Exchangeable Share Consideration representing the total Redemption Call
       Purchase Price. Provided that such Exchangeable Share Consideration has
       been so deposited with the Transfer Agent,
 
                                      
<PAGE>
       on and after the Automatic Redemption Date the rights of each holder of
       Exchangeable Shares will be limited to receiving such holder's
       proportionate part of the total Redemption Call Purchase Price payable by
       Subco upon presentation and surrender by the holder of certificates
       representing the Exchangeable Shares held by such holder and the holder
       shall on and after the Automatic Redemption Date be considered and deemed
       for all purposes to be the holder of the PRI Common Stock delivered to
       such holder. Upon surrender to the Transfer Agent of a certificate or
       certificates representing Exchangeable Shares, together with such other
       documents and instruments as may be required to effect a transfer of
       Exchangeable Shares under the CBCA and the by-laws of Promis and such
       additional documents and instruments as the Transfer Agent may reasonably
       require, the holder of such surrendered certificate or certificates shall
       be entitled to receive in exchange therefor, and the Transfer Agent on
       behalf of Subco shall deliver to such holder, the Exchangeable Share
       Consideration to which the holder is entitled. If Subco does not exercise
       the Redemption Call Right in the manner described above, on the Automatic
       Redemption Date the holders of the Exchangeable Shares will be entitled

if all dividends on the outstanding Exchangeable Shares corresponding to
dividends declared with a record date on or following the effective date of the
Plan of Arrangement on the PRI Common Stock shall have been declared on the

    5.1 In the event of the liquidation, dissolution or winding-up of the
Corporation or any other distribution of the assets of the Corporation among its
shareholders for the purpose of winding-up its affairs, a holder of Exchangeable
Shares shall be entitled, subject to applicable law, to receive from the assets
of the Corporation in respect of each Exchangeable Share held by such holder on
the effective date of such liquidation, dissolution or winding-up (the

Price applicable on the last Business Day prior to the Liquidation Date (the

    5.2 On or promptly after the Liquidation Date, and subject to the exercise
by Subco of the Liquidation Call Right, the Corporation shall cause to be
delivered to the holders of the Exchangeable Shares the Liquidation Amount for
each such Exchangeable Share upon presentation and surrender of the certificates
representing such Exchangeable Shares, together with such other documents and
instruments as may be required to effect a transfer of Exchangeable Shares under
the Act and the by-laws of the Corporation and such additional documents and
instruments as the Transfer Agent may reasonably require, at the registered
office of the Corporation or at any office of the Transfer Agent as may be
specified by the Corporation by notice to the holders of the Exchangeable
Shares. Payment of the total Liquidation Amount for such Exchangeable Shares
shall be made by delivery to each holder, at the address of the holder recorded
in the securities register of the Corporation for the Exchangeable Shares or by
holding for pick up by the holder at the registered office of the Corporation or
at any office of the Transfer Agent as may be specified by the Corporation by
notice to the holders of Exchangeable Shares, on behalf of the Corporation of
the Exchangeable Share Consideration representing the total Liquidation Amount.
On and after the Liquidation Date, the holders of the Exchangeable Shares shall
cease to be holders of such Exchangeable Shares and shall not be entitled to
exercise any of the rights of holders in respect thereof, other than the right
to receive their proportionate part of the total Liquidation Amount, unless
payment of the total Liquidation Amount for such Exchangeable Shares shall not
be made upon presentation and surrender of share certificates in accordance with
the foregoing provisions, in which case the rights of the holders shall remain
unaffected until the total Liquidation Amount has been paid in the manner
hereinbefore provided. The Corporation shall have the right at any time on or
after the Liquidation

respect of the Exchangeable Shares represented by certificates that have not at
the Liquidation Date been surrendered by the holders thereof in a custodial
account or for safe keeping, in the case of non-cash items, with any chartered
bank or trust company in Canada. Upon such deposit being made, the rights of the
holders of Exchangeable Shares after such deposit shall be limited to receiving
their proportionate part of the total Liquidation Amount for such Exchangeable
Shares so deposited, against presentation and surrender of the said certificates
held by them, respectively, in accordance with the foregoing provisions. Upon
such payment or deposit of such Exchangeable Share Consideration, the holders of
the Exchangeable Shares shall thereafter be considered and deemed for all
purposes to be the holders of the PRI Common Stock delivered to them.
Notwithstanding the foregoing, until such payment or deposit of such
Exchangeable Share Consideration, the holder shall be deemed to still be a
holder of Exchangeable Shares for purposes of all voting rights with respect
thereto under the Voting and Exchange Trust Agreement.
 
    5.3 After the Corporation has satisfied its obligations to pay the holders
of the Exchangeable Shares the Liquidation Amount per Exchangeable Share, such
holders shall not be entitled to share in any further distribution of the assets
of the Corporation.

or all of the Exchangeable Shares registered in the name of such holder for an
amount equal to the Exchangeable Share Price applicable on the last Business Day
prior to the Retraction Date (the "RETRACTION PRICE"). In connection with
payment of the Retraction Price, the Corporation shall be entitled to liquidate
some of the PRI Common Stock that would otherwise be deliverable to the
particular holder of Exchangeable Shares in order to fund any statutory
withholding tax obligation. To effect such redemption, the holder shall present
and surrender at the registered office of the Corporation or at any office of
the Transfer Agent as may be specified by the Corporation in Schedule A hereto

         Retraction Request is received by the Corporation and further provided
         that, in the event that no such Business Day is specified by the holder
         in the Retraction Request, the Retraction Date shall be deemed to be
         the tenth Business Day after the date on which the Retraction Request
         is received by the Corporation; and
 
   (iii) acknowledging the overriding right (the "RETRACTION CALL RIGHT") of
         Subco to purchase all but not less than all of the Retracted Shares
         directly from the holder and that the Retraction Request shall be
         deemed to be a revocable offer by the holder to sell the Retracted
         Shares in accordance with the Retraction Call Right on the terms and
         conditions set out in Section 6.3 below.
 
    6.2 Subject to the exercise by Subco of the Retraction Call Right, upon
receipt by the Corporation or the Transfer Agent in the manner specified in
Section 6.1 hereof of a certificate or certificates representing the
number of Exchangeable Shares which the holder desires to have the Corporation
redeem, together with a Retraction Request, and provided that the Retraction
Request is not revoked by the holder in the manner
 
                                      
<PAGE>
specified in Section 6.7, the Corporation shall redeem the Retracted Shares
effective at the close of business on the Retraction Date and shall cause to be
delivered to such holder the total Retraction Price with respect to such shares
in accordance with Section 6.4 hereof. If only a part of the Exchangeable Shares
represented by any certificate are redeemed or purchased by Subco pursuant to
the Retraction Call right, a new certificate for the balance of such
Exchangeable Shares shall be issued to the holder at the expense of the
Corporation.
 
    6.3 Upon receipt by the Corporation of a Retraction Request, the Corporation
shall immediately notify Subco and PRI thereof. In order to exercise the
Retraction Call Right, Subco must notify the Corporation in writing of its
determination to do so (the "SUBCO CALL NOTICE") within two Business Days of
such notification. If Subco does not so notify the Corporation within two
Business Days, the Corporation will notify the holder as soon as possible
thereafter that Subco will not exercise the Retraction Call Right. If Subco
delivers the Subco Call Notice within such two Business Days, and provided that
the Retraction Request is not revoked by the holder in the manner specified in
Section 6.7, the Retraction Request shall thereupon be considered only to be an
offer by the holder to sell the Retracted Shares to Subco in accordance with the
Retraction Call Right. In such event, the Corporation shall not redeem the
Retracted Shares and Subco shall purchase from such holder and such holder shall
sell to Subco on the Retraction Date the Retracted Shares for a purchase price
(the "PURCHASE PRICE") per share equal to the Retraction Price per share. For
the purposes of completing a purchase pursuant to the Retraction Call Right,
Subco shall deposit with the Transfer Agent, on or before the Retraction Date
the Exchangeable Share Consideration representing the total Purchase Price.
Provided that such Exchangeable Share Consideration has been so deposited with
the Transfer Agent, the closing of the purchase and sale of the Retracted Shares
pursuant to the Retraction Call Right shall be deemed to have occurred as at the
close of business on the Retraction Date and, for greater certainty, no
redemption by the Corporation of such Retracted Shares shall take place on the
Retraction Date. In the event that Subco does not deliver a Subco Call Notice
within two Business Days or otherwise comply with these Exchangeable Share
provisions in respect thereto, and provided that Retraction Request is not
revoked by the holder in the manner specified in Section 6.7, the Corporation
shall redeem the Retracted Shares on the Retraction Date and in the manner
otherwise contemplated in this Article 6.
 
    6.4 The Corporation or Subco, as the case may be, shall deliver or cause the
Transfer Agent to deliver to the relevant holder, at the address of the holder
recorded in the securities register of the Corporation for the Exchangeable
Shares or at the address specified in the holder's Retraction Request or by
holding for pick up by the holder at the registered office of the Corporation or
at any office of the Transfer Agent as may be specified by the Corporation by
notice to the holders of Exchangeable Shares, the Exchangeable Share
Consideration representing the total Retraction Price or the total Purchase
Price, as the case may be, and such delivery of such Exchangeable Share
Consideration to the Transfer Agent shall be deemed to be payment of and shall
satisfy and discharge all liability for the total Retraction Price or total
Purchase Price, as the case may be, except as to any cheque included therein
which is not paid on due presentation.
 
    6.5 On and after the close of business on the Retraction Date, the holder of
the Retracted Shares shall not be entitled to exercise any of the rights of a
holder in respect thereof, other than the right to receive his proportionate
part of the total Retraction Price or total Purchase Price, as the case may be,
unless upon presentation and surrender of certificates in accordance with the
foregoing provisions, payment of the total Retraction Price or the total
Purchase Price, as the case may be, shall not be made, in which case the rights
of such holder shall remain unaffected until the Exchangeable Share
Consideration representing the total Retraction Price or the total Purchase
Price, as the case may be, has been paid in the manner hereinbefore provided. On
and after the close of business on the Retraction Date, provided that
presentation and surrender of certificates and payment of the Exchangeable Share
Consideration representing the total Retraction Price or the total Purchase
Price, as the case may be, has been made in accordance with the foregoing
provisions, the holder of the Retracted Shares so redeemed by the Corporation or
purchased by Subco shall thereafter be considered and deemed for all purposes to
be a holder of the PRI Common Stock delivered to it. Notwithstanding the
foregoing, until payment of such Exchangeable Share Consideration to the holder,
the holder shall be deemed to still be a holder of Exchangeable Shares for
purposes of all voting rights with respect thereto under the Voting and Exchange
Trust Agreement.
 
    6.6 Notwithstanding any other provision of this Article 6, the Corporation
shall not be obligated to redeem Retracted Shares specified by a holder in a
Retraction Request to the extent that such redemption of Retracted
 
                                      
<PAGE>
Shares would be contrary to liquidity or solvency requirements or other
provisions of applicable law. If the Corporation believes that on any Retraction
Date it would not be permitted by any of such provisions to redeem the Retracted
Shares tendered for redemption on such date, and provided that Subco shall not
have exercised the Retraction Call Right with respect to the Retracted Shares,
the Corporation shall only be obligated to redeem Retracted Shares specified by
a holder in a Retraction Request to the extent of the maximum number that may be
so redeemed (rounded down to a whole number of shares) as would not be contrary
to such provisions and shall notify the holder at least two Business Days prior
to the Retraction Date as to the number of Retracted Shares which will not be
redeemed by the Corporation. In any case in which the redemption by the
Corporation of Retracted Shares would be contrary to liquidity or solvency
requirements or other provisions of applicable law, the Corporation shall redeem
Retracted Shares in accordance with Section 6.2 of these share provisions on a
pro rata basis and shall issue to each holder of Retracted Shares a new
certificate, at the expense of the Corporation, representing the Retracted
Shares not redeemed by the Corporation pursuant to Section 6.2 hereof. Provided
that the Retraction Request is not revoked by the holder in the manner specified
in section 6.7, the holder of any such Retracted Shares not redeemed by the
Corporation pursuant to Section 6.2 of these share provisions as a result of
liquidity or solvency requirements or applicable law shall be deemed by giving
the Retraction Request to require Subco to purchase such Retracted Shares from
such holder on the Retraction Date or as soon as practicable thereafter on
payment by Subco to such holder of the Purchase Price for each such Retracted
Share, all as more specifically provided in the Voting and Exchange Trust
Agreement, and Subco shall make such purchase.
 
    6.7 A holder of Retracted Shares may, by notice in writing given by the
holder to the Corporation before the close of business on the Business Day
immediately preceding the Retraction Date, withdraw its Retraction Request in
which event such Retraction Request shall be null and void and, for greater
certainty, the revocable offer constituted by the Retraction Request to sell the
Retracted Shares to Subco shall be deemed to have been revoked.
 
                                   ARTICLE 7
              REDEMPTION OF EXCHANGEABLE SHARES BY THE CORPORATION
 
    7.1 Subject to applicable law, and if Subco does not exercise the Redemption
Call Right, the Corporation shall on the Automatic Redemption Date redeem the
whole of the then outstanding Exchangeable Shares for an amount equal to the
Exchangeable Share Price applicable on the last Business Day prior to the
Automatic Redemption Date (the "REDEMPTION PRICE"). In connection with payment
of the Redemption Price, the Corporation shall be entitled to liquidate some of
the PRI Common Stock which would otherwise be deliverable to the particular
holder of Exchangeable Shares in order to fund any statutory withholding tax
obligation.
 
    7.2 In any case of a redemption of Exchangeable Shares under this Article 7,
the Corporation, or the Transfer Agent on behalf of the Corporation, shall, at
least 45 days before the relevant Automatic Redemption Date or such number of
days as the Board of Directors may determine to be reasonably practicable under
the circumstances in respect of a possible Automatic Redemption Date arising in
connection with a PRI Control Transaction, a Promis Control Transaction, or a
matter described in paragraphs (c) or (d) of the definition of Automatic
Redemption Date in Article 1.1, the Corporation shall send to each holder of
Exchangeable Shares a notice in writing of the redemption or possible redemption
by the Corporation or the purchase by Subco under the Redemption Call Right, as
the case may be, of the Exchangeable Shares held by such holder. Such notice
shall set out the formula for determining the Redemption Price or the Redemption
Call Purchase Price, as the case may be, the Automatic Redemption Date and, if
applicable, particulars of the Redemption Call Right. In the case of any notice
given in connection with a possible Automatic Redemption Date, such notice will
be given contingently and will be withdrawn if the contingency does not occur.
 
    7.3 On or after the Automatic Redemption Date and subject to the exercise by
Subco of the Redemption Call Right, the Corporation shall cause to be delivered
to the holders of the Exchangeable Shares to be redeemed the Redemption Price
for each such Exchangeable Share upon presentation and surrender at the
registered office of the Corporation or at any office of the Transfer Agent as
may be specified by the Corporation in such notice of the certificates
representing such Exchangeable Shares, together with such other documents and
instruments as may be required to effect a transfer of Exchangeable Shares under
the Act and the by-laws of the Corporation and such additional documents and
instruments as the Transfer Agent may
 
                                      
<PAGE>
reasonably require. Payment of the total Redemption Price for such Exchangeable
Shares shall be made by delivery to each holder, at the address of the holder
recorded in the securities register or at any office of the Transfer Agent as
may be specified by the Corporation in such notice, on behalf of the Corporation
of the Exchangeable Share Consideration representing the total Redemption Price.
On and after the Automatic Redemption Date, the holders of the Exchangeable
Shares called for redemption shall cease to be holders of such Exchangeable
Shares and shall not be entitled to exercise any of the rights of holders in
respect thereof, other than the right to receive their proportionate part of the
total Redemption Price, unless payment of the total Redemption Price for such
Exchangeable Shares shall not be made upon presentation and surrender of
certificates in accordance with the foregoing provisions, in which case the
rights of the holders shall remain unaffected until the total Redemption Price
has been paid in the manner hereinbefore provided. The Corporation shall have
the right at any time after the sending of notice of its intention to redeem the
Exchangeable Shares as aforesaid to deposit or cause to be deposited the
Exchangeable Shares Consideration with respect to the Exchangeable Shares so
called for redemption, or of such of the said Exchangeable Shares represented by
certificates that have not at the date of such deposit been surrendered by the
holders thereof in connection with such redemption, in a custodial account or
for safe keeping, in the case of non-cash items, with any chartered bank or
trust company in Canada named in such notice, Upon the later of such deposit
being made and the Automatic Redemption Date, the Exchangeable Shares in respect
whereof such deposit shall have been made shall be redeemed and the rights of
the holders thereof after such deposit or Automatic Redemption Date, as the case
may be, shall be limited to receiving their proportionate part of the total
Redemption Price for such Exchangeable Shares so deposited, against presentation
and surrender of the said certificates held by them, respectively, in accordance
with the foregoing provisions. Upon such payment or deposit of such Exchangeable
Share Consideration, the holders of the Exchangeable Shares shall thereafter be
considered and deemed for all purposes to be holders of the PRI Common Stock
delivered to them. Notwithstanding the foregoing, until such payment or deposit
of such Exchangeable Share Consideration is made, the holder shall be deemed to
still be a holder of Exchangeable Shares for purposes of all voting rights with
respect thereto under the Voting and Exchange Trust Agreement.
 
                                   ARTICLE 8
                               EXCHANGE PUT RIGHT
 
    8.1 Upon and subject to the terms and conditions contained in the
Exchangeable Share Provisions and the Voting and Exchange Trust Agreement:
 
    (a) a holder of Exchangeable Shares shall have the right (the "Exchange Put
       Right") at any time to require Subco to purchase all or any part of the
       Exchangeable Shares of the holder; and
 
    (b) upon the exercise by the holder of the Exchange Put Right and provided
       that, at the time of purchase, the Exchangeable Shares are listed on a
       recognized Canadian stock exchange, the holder shall be required to sell
       to Subco, and Subco shall be required to purchase from the holder, that
       number of Exchangeable Shares in respect of which the Exchange Put Right
       is exercised, in consideration of the payment by Subco of the
       Exchangeable Share Price applicable thereto (which shall be the
       Exchangeable Share Price applicable on the last Business Day prior to
       receipt of notice required under section 8.2) and delivery by or on
       behalf of Subco of the Exchangeable Share Consideration representing the
       total applicable Exchangeable Share Price.
 
    8.2 The Exchange Put Right provided in section 8.1 hereof and in Article 5
of the Voting and Exchange Trust Agreement may be exercised at any time by
notice in writing given by the holder to and received by the Trustee (the date
of such receipt, the "Exchange Put Date") accompanied by presentation and
surrender of the certificates representing such Exchangeable Shares, together
with such documents and instruments as may be required to effect a transfer of
Exchangeable Shares under the Act and the by-laws of the Corporation and such
additional documents and instruments as the Trustee may reasonably require, at
the principal transfer office in Toronto, Ontario of the Trustee, or at such
other office or offices of the Trustee or of other persons designated by the
Trustee for that purpose as may from time to time be maintained by the Trustee
for that purpose. Such notice may be (i) in the form of the panel, if any, on
the certificates representing Exchangeable Shares, (ii) in the form of the
notice and election contained in any letter of transmittal distributed or made
available by the Corporation for that purpose, or (iii) in other form
satisfactory to the Trustee (or such other persons aforesaid),
 
                                      
<PAGE>
shall stipulate the number of Exchangeable Shares in respect of which the right
is exercised (which may not exceed the number of shares represented by
certificates surrendered to the Trustee), shall be irrevocable unless the
exchange is not completed in accordance herewith and with the Voting and
Exchange Trust Agreement and shall constitute the holder's authorization to the
Trustee (and such other persons aforesaid) to effect the exchange on behalf of
the holder.
 
    8.3 The completion of the sale and purchase referred to in section 8.1 shall
be required to occur, and Subco shall be required to take all actions on its
part necessary to permit it to occur, not later than the close of business on
the third Business Day following the Exchange Put Date.
 
    8.4 The surrender by the holder of Exchangeable Shares under section 8.2
shall constitute the representation, warranty and covenant of the holder that
the Exchangeable Shares so purchased are sold free and clear of any lien,
encumbrance, security interest or adverse claim or interest.
 
    8.5 If a part only of the Exchangeable Shares represented by any certificate
are to be sold and purchased pursuant to the exercise of the Exchange Put Right,
a new certificate for the balance of such Exchangeable Shares shall be issued to
the holder at the expense of the Corporation.
 
    8.6 Upon receipt by the Trustee of the notice, certificates and other
documents or instruments required by section 8.2, the Trustee shall deliver or
cause to be delivered, on behalf of Subco and subject to receipt by the Trustee
from Subco of the applicable Exchangeable Share Consideration, to the relevant
holder at the address of the holder specified in the notice or by holding for
pick-up by the holder at the registered office of the Corporation or at any
office of the Trustee (or other persons aforesaid) maintained for that purpose,
the Exchangeable Share Consideration representing the total applicable
Exchangeable Share Price, within the time stipulated in section 8.3. Delivery by
Subco to the Trustee of such Exchangeable Share Consideration shall be deemed to
be payment of and shall satisfy and discharge all liability for the total
applicable Exchangeable Share Price, except as to any cheque included therein
which is not paid on due presentation.
 
    8.7 On and after the close of business on the Exchange Put Date, the holder
of the Exchangeable Shares in respect of which the Exchange Put Right is
exercised shall not be entitled to exercise any of the rights of a holder in
respect thereof, other than the right to receive the total applicable
Exchangeable Share Price, unless upon presentation and surrender of certificates
in accordance with the foregoing provisions, payment of the Exchangeable Share
Consideration shall not be made, in which case the rights of such holder shall
remain unaffected until such payment has been made. On and after the close of
business on the Exchange Put Date provided that presentation and surrender of
certificate and payment of the Exchangeable Share Consideration has been made in
accordance with the foregoing provisions, the holder of the Exchangeable Shares
so purchased by Subco shall thereafter be considered and deemed for all purposes
to be a holder of the PRI Common Stock delivered to it. Notwithstanding the
foregoing, until payment of the Exchangeable Share Consideration to the holder,
the holder shall be deemed to still be a holder of Exchangeable Shares for
purposes of all voting rights with respect thereto under the Voting and Exchange
Trust Agreement.
 
                                   ARTICLE 9
                                 VOTING RIGHTS
 
    9.1 Except as required by applicable law and the provisions hereof, the
holders of the Exchangeable Shares shall not be entitled as such to receive
notice of or to attend any meeting of the shareholders of the Corporation or to
vote at any such meeting.
 
                                   ARTICLE 10
                             AMENDMENT AND APPROVAL
 
   10.1 The rights, privileges, restrictions and conditions attaching to the
Exchangeable Shares may be added to, changed or removed but, except, as
hereinafter provided, only with the approval of the holders of the Exchangeable
Shares given as hereinafter specified.
 
   10.2 Any approval given by the holders of the Exchangeable Shares to add to,
change or remove any right, privilege, restriction or condition attaching to the
Exchangeable Shares or any other matter requiring the approval or consent of the
holders of the Exchangeable Shares shall be deemed to have been sufficiently
given if
 
                                      
<PAGE>
it shall have been given in accordance with applicable law subject to a minimum
requirement that such approval be evidenced by resolution passed by not less
than 50% (or such higher percentage as may be required by law) of the votes cast
on such resolution by persons represented in person or by proxy at a meeting of
holders of Exchangeable Shares duly called and held at which the holders of at
least 50% of the outstanding Exchangeable Shares at that time are present or
represented by proxy (excluding Exchangeable Shares beneficially owned by PRI or
its Subsidiaries). If at any such meeting the holders of at least 50% of the
outstanding Exchangeable Shares at that time are not present or represented by
proxy within one-half hour after the time appointed for such meeting then the
meeting shall be adjourned to such date not less than 10 days thereafter and to
such time and place as may be designated by the Chairman of such meeting. At
such adjourned meeting the holders of Exchangeable Shares present or represented
by proxy thereat may transact the business for which the meeting was originally
called and a resolution passed thereat by the affirmative vote of not less than
50% (or such higher percentage as may be required by law) of the votes cast on
such resolution by persons represented in person or by proxy at such meeting
shall constitute the approval or consent of the holders of the Exchangeable
Shares. For the purposes of this section, any spoiled votes, illegible votes,
defective votes and abstinences shall be deemed to be votes not cast.
 
                                   ARTICLE 11
            RECIPROCAL CHANGES, ETC. IN RESPECT OF PRI COMMON STOCK
 
   11.1 (a) Each holder of an Exchangeable Share acknowledges that the Support
Agreement provides, in part, that PRI will not:
 
    (i) issue or distribute PRI Common Stock (or securities exchangeable for or
        convertible into or carrying rights to acquire shares of PRI Common
        Stock) to the holders of all or substantially all of the then
        outstanding PRI Common Stock by way of stock dividend or other
        distribution; or
 
    (ii) issue or distribute rights, options or warrants to the holders of all
         or substantially all of the then outstanding PRI Common Stock entitling
         them to subscribe for or to purchase shares of PRI Common Stock (or
         securities exchangeable for or convertible into or carrying rights to
         acquire shares of PRI Common Stock); or
 
   (iii) issue or distribute to the holders of all or substantially all of the
         then outstanding shares of PRI Common Stock (A) shares or securities of
         PRI of any class other than PRI Common Stock (other than shares
         convertible into or exchangeable for or carrying rights to acquire PRI

rights, options, warrants, securities, shares, evidences of indebtedness or

Agreement further provides, in part, that PRI will not:
 
    (i) subdivide, redivide or change the then outstanding shares of PRI Common
        Stock into a greater number of shares of PRI Common Stock; or
 
    (ii) reduce, combine or consolidate or change the then outstanding shares of
         PRI Common Stock into a lesser number of shares of PRI Common Stock; or
 
   (iii) reclassify or otherwise change the shares of PRI Common Stock or effect
         an amalgamation, merger, reorganization or other transaction involving

the same or an economically equivalent change to, or in the rights of the
holders of, the Exchangeable Shares and the same or an economically equivalent
change is simultaneously made to, or in the rights of the holders of, the
Exchangeable Shares.
 
                                      
<PAGE>

Articles of Organization without the approval of the holders of the Exchangeable
Shares given in accordance with Article 10 of these share provisions other than
such amendments, waivers and/or forgiveness as may be necessary or advisable for

       provided to stockholders of Parent;
 
    (b) a statement that such Holder is entitled to instruct the Trustee as to
       the exercise of the Holder Votes with respect to such Parent Meeting or

       thereat;
 
    (c) a statement as to the manner in which such instructions may be given to

       revoking or amending such instructions.
 
    The materials referred to above are to be provided by Parent to the Trustee,
but shall be subject to review and comment by the Trustee.
 
    For the purpose of determining Holder Votes to which a Holder is entitled in
respect of any such Parent Meeting or Parent Consent, the number of Exchangeable
Shares owned of record by the Holder shall be determined at the close of
business on the record date established by Parent or by applicable law for
purposes of determining stockholders entitled to vote at such Parent Meeting or
to give written consent in connection with
 
 
<PAGE>
such Parent Consent. Parent will notify the Trustee of any decision of the board
of directors of Parent with respect to the calling of any such Parent Meeting or
the seeking of any such Parent Consent and shall provide all necessary
information and materials to the Trustee in each case promptly and in any event
in sufficient time to enable the Trustee to perform its obligations contemplated

       Common Stock; or
 
    (b) specifically directed to the Holders or to the Trustee for the benefit
       of the Holders by Parent.
 
    4.6  OTHER MATERIALS.  As soon as reasonably practicable after receipt by
Parent or any stockholder of Parent (if such receipt is known by Parent) of any
material sent or given generally to the holders of Parent Common Stock by or on
behalf of a third party, including without limitation dissident proxy and
information circulars (and related information and material) and tender and
exchange offer circulars (and related information and material), Parent shall
use its reasonable efforts to obtain and deliver to the Trustee copies thereof
in sufficient quantities so as to enable the Trustee to forward such material
(unless the same has been provided directly to Holders by such third party) to
each Holder as soon as possible thereafter. As soon as practicable after receipt
thereof, the Trustee will mail or otherwise send to each Holder, at the expense
of Parent, copies of all such materials received by the Trustee from Parent. The
Trustee will also make copies of all such materials available for inspection by
any Holder at the Trustee's principal trust office in the city of Toronto.
 
    4.7  LIST OF PERSONS ENTITLED TO VOTE.  The Company shall, (a) prior to each
annual and special Parent Meeting or the seeking of any Parent Consent and (b)
forthwith upon each request made at any time by the Trustee in writing, prepare
or cause to be prepared a list (a "List") of the names and addresses of the
Holders arranged in alphabetical order and showing the number of Exchangeable
Shares held of record by each such Holder, in each case at the close of business
on the date specified by the Trustee in such request or, in the case of a List
prepared in connection with a Parent Meeting or a Parent Consent, at the close
of business on the record date established by Parent or pursuant to applicable
law for determining the holders of Parent Common Stock entitled to receive
notice of and/or to vote at such Parent Meeting or to give consent in connection
with such Parent Consent. Each such List shall be delivered to the Trustee
promptly after receipt by the Company of such request or the record date for
such meeting or seeking of consent, as the case may be, and in any event within
sufficient time as to enable the Trustee to perform its obligations under this
Agreement. Parent agrees to give the Company written notice (with a copy to the
Trustee) of the calling of any Parent Meeting or the seeking of any Parent
Consent, together with the record dates therefor, sufficiently prior to the date
of the calling of such meeting or seeking of such consent so as to enable the
Company to perform its obligations under this Section 4.7.
 
    4.8  ENTITLEMENT TO DIRECT VOTES.  Any Holder named in a List prepared in
connection with any Parent Meeting or any Parent Consent will be entitled (a) to
instruct the Trustee in the manner described in Section 4.4 hereof with respect
to the exercise of the Holder Votes to which such Holder is entitled or (b) to
attend such meeting and personally to exercise thereat (or to exercise with
respect to any written consent), as the proxy of the Trustee, the Holder Votes
to which such Holder is entitled.

    4.9  VOTING BY TRUSTEE, AND ATTENDANCE OF TRUSTEE REPRESENTATIVE, AT
MEETING.
 
    (a) In connection with each Parent Meeting and Parent Consent, the Trustee
shall exercise, either in person or by proxy, in accordance with the
instructions received from a Holder pursuant to Section 4.4 hereof, the Holder
Votes as to which such Holder is entitled to direct the vote (or any lesser
number thereof as may be set forth in the instructions); provided, however, that
such written instructions are received by the Trustee from the Holder prior to
the time and date fixed by the Trustee for receipt of such instructions in the
notice given by the Trustee to the Holder pursuant to Section 4.4 hereof.
 
    (b) The Trustee shall cause a representative who is empowered by it to sign
and deliver, on behalf of the Trustee, proxies for Voting Rights to attend each
Parent Meeting. Upon submission by a Holder (or its designee) of identification
satisfactory to the Trustee's representative, and at the Holder's request, such
representative shall sign and deliver to such Holder (or its designee) a proxy
to exercise personally the Holder Votes as to which such Holder is otherwise
entitled hereunder to direct the vote, if such Holder either:
 
    (i) has not previously given the Trustee instructions pursuant to Section
        4.4 hereof in respect of such meeting, or
 
    (ii) submits to the Trustee's representative written revocation of any such
         previous instructions.
 
    At such meeting, the Holder exercising such Holder Votes shall have the same
rights as the Trustee to speak at the meeting in respect of any matter, question
or proposition, to vote by way of ballot at the meeting in respect of any
matter, question or proposition, and to vote at such meeting by way of a show of
hands in respect of any matter, question or proposition.
 
    4.10  DISTRIBUTION OF WRITTEN MATERIALS.  Any written materials to be
distributed by the Trustee to the Holders pursuant to this Agreement shall be
sent by mail (or otherwise communicated in the same manner as Parent utilizes in
communications to holders of Parent Common Stock) to each Holder at its address
as shown on the books of the Company. The Company shall provide or cause to be
provided to the Trustee for this purpose, on a timely basis and without charge
or other expense:
 
    (a) a current List; and
 
    (b) on the request of the Trustee, mailing labels to enable the Trustee to
       carry out its duties under this Agreement.
 
    4.11  TERMINATION OF VOTING RIGHTS.  Except as otherwise provided herein or
in the Exchangeable Share Provisions, all of the rights of a Holder with respect
to the Holder Votes exercisable in respect of the Exchangeable Shares held by
such Holder, including the right to instruct the Trustee as to the voting of or
to vote personally such Holder Votes, shall be deemed to be surrendered by the
Holder to Parent or Subco, as the case may be, and such Holder Votes and the
Voting Rights represented thereby shall cease immediately, upon the delivery by
such Holder to the Trustee of the certificates representing such Exchangeable
Shares in connection with the exercise by the Holder of the Exchange Put Right
or the Exchange Right or the occurrence of the automatic exchange of
Exchangeable Shares for shares of Parent Common Stock, as specified in Article 5
hereof (unless in any case Parent or Subco shall not have delivered the
Exchangeable Share Consideration deliverable in exchange therefor to the Trustee
for delivery to the Holders), or upon the redemption of Exchangeable Shares
pursuant to Article 6 or Article 7 of the Exchangeable Share Provisions, or upon
the effective date of the liquidation, dissolution or winding-up of the Company
or any other distribution of the assets of the Company among its shareholders
for the purpose of winding up its affairs pursuant to Article 5 of the
Exchangeable Share Provisions, or upon the purchase of Exchangeable Shares from
the holder thereof by Subco pursuant to the exercise by Subco of the Retraction

    5.1  GRANT AND OWNERSHIP OF THE EXCHANGE RIGHT.  Subco hereby grants to the
Trustee as trustee for and on behalf of, and for the use and benefit of, the

Insolvency Event, to require Subco to purchase from each or any Holder all or
any part of the Exchangeable Shares held by the Holders, all in accordance with
the provisions of this Agreement and the Exchangeable Share Provisions, as the
case may be. Subco hereby acknowledges receipt from the Trustee as trustee for
and on behalf of the Holders of good and valuable consideration (and the
adequacy thereof) for the grant of the Exchange Put Right and the Exchange Right
by Subco to the Trustee. During the term of the Trust and subject to the terms
and conditions of this Agreement, the Trustee shall possess and be vested with
full legal ownership of the Exchange Put Right and the Exchange Right and shall
be entitled to exercise all of the rights and powers of an owner with respect to
the Exchange Put Right and the Exchange Right, provided that the Trustee shall:
 
    (i) hold the Exchange Put Right and the Exchange Right and the legal title
        thereto as trustee solely for the use and benefit of the Holders in
        accordance with the provisions of this Agreement; and
 
    (ii) except as specifically authorized by this Agreement, have no power or
         authority to exercise or otherwise deal in or with the Exchange Put
         Right or the Exchange Right, and the Trustee shall not exercise any
         such rights for any purpose other than the purposes for which this
         Trust is created pursuant to this Agreement.
 
    5.2  GRANT AND OWNERSHIP OF THE AUTOMATIC EXCHANGE RIGHTS.  Parent and Subco
hereby jointly and severally grant to the Trustee as trustee for and on behalf
of, and for the use and benefit of, the Holders the Automatic Exchange Rights in
accordance with the provisions of this Agreement. Parent and Subco hereby
acknowledge receipt from the Trustee as trustee for and on behalf of the Holders
of good and valuable consideration (and the adequacy thereof) for the grant of
the Automatic Exchange Rights by Parent and Subco to the Trustee. During the
term of the Trust and subject to the terms and conditions of this Agreement, the
Trustee shall possess and be vested with full legal ownership of the Automatic
Exchange Rights and shall be entitled to exercise all of the rights and powers
of an owner with respect to the Automatic Exchange Rights, provided that the
Trustee shall:
 
    (a) hold the Automatic Exchange Rights and the legal title thereto as
       trustee solely for the use and benefit of the Holders in accordance with
       the provisions of this Agreement; and
 
    (b) except as specifically authorized by this Agreement, have no power or
       authority to exercise or otherwise deal in or with the Automatic Exchange
       Rights, and the Trustee shall not exercise such rights for any purpose
       other than the purposes for which this Trust is created pursuant to this
       Agreement.
 
    5.3  LEGENDED SHARE CERTIFICATES.  The Company will cause each certificate
representing Exchangeable Shares to bear an appropriate legend notifying the
Holders of:
 
    (a) their right to instruct the Trustee with respect to the exercise of the
       Exchange Put Right and the Exchange Right in respect of the Exchangeable
       Shares held by a Holder, and
 
    (b) the Automatic Exchange Rights.
 
    5.4  GENERAL EXERCISE OF EXCHANGE PUT RIGHT AND EXCHANGE RIGHT.  The
Exchange Put Right and the Exchange Right shall be and remain vested in and
exercised by the Trustee. Subject to Section 7.15 hereof, the Trustee shall
exercise the Exchange Put Right and the Exchange Right only on the basis of
instructions received pursuant to this Article 5 from Holders entitled to
instruct the Trustee as to the exercise thereof. To the extent that no
instructions are received from a Holder with respect to the Exchange Put Right
and the Exchange Right, the Trustee shall not exercise or permit the exercise of
the Exchange Put Right and the Exchange Right.
 
    5.5  PURCHASE PRICE.  The purchase price payable by Subco for each
Exchangeable Share to be purchased by Subco (a) under the Exchange Put Right
shall be the amount determined under the Exchangeable Share Provisions, and (b)
under the Exchange Right shall be an amount equal to the Exchangeable Share
Price on the last Business Day prior to the day of closing of the purchase and
sale of such Exchangeable Share under the Exchange Right. In connection with
each exercise of the Exchange Right, Subco will provide to the Trustee an
Officer's Certificate setting forth the calculation of the applicable
Exchangeable Share Price for each Exchangeable Share. The applicable
Exchangeable Share Price for each such Exchangeable Share so purchased may be
satisfied only by Subco's issuing and delivering or causing to be delivered to
the Trustee, on behalf of the
 
 
<PAGE>
relevant Holder, the applicable Exchangeable Share Consideration representing
the total applicable Exchangeable Share Price (less any amounts withheld
pursuant to Section 5.14 hereof).
 
    5.6  EXERCISE INSTRUCTIONS.  Subject to the terms and conditions set forth
herein, a Holder shall be entitled, upon the occurrence and during the
continuance of an Insolvency Event, to instruct the Trustee to exercise the
Exchange Right with respect to all or any part of the Exchangeable Shares
registered in the name of such Holder on the books of the Company. To cause the
exercise of the Exchange Right by the Trustee, the Holder shall deliver to the
Trustee, in person or by certified or registered mail, at its principal trust
office in Toronto, Ontario or at such other places in Canada as the Trustee may
from time to time designate by written notice to the Holders, the certificates
representing the Exchangeable Shares which such Holder desires Subco to
purchase, duly endorsed in blank, and accompanied by such other documents and
instruments as may be required to effect a transfer of Exchangeable Shares under
the CBCA and the by-laws of the Company and such additional documents and
instruments as the Trustee may reasonably require, together with:
 
    (a) a duly completed form of notice of exercise of the Exchange Right,
       contained on the reverse of or attached to the Exchangeable Share
       certificates, stating:
 
        (i) that the Holder thereby instructs the Trustee to exercise the
            Exchange Right so as to require Subco to purchase from the Holder
            the number of Exchangeable Shares specified therein,
 
        (ii) that such Holder has good title to and owns all such Exchangeable
             Shares to be acquired by Subco free and clear of all liens, claims,
             encumbrances, security interests and adverse claims or interests,
 
       (iii) the names in which the certificates representing Parent Common
             Stock issuable in connection with the exercise of the Exchange
             Right are to be issued, and
 
        (iv) the names and addresses of the persons to whom the Exchangeable
             Share Consideration should be delivered; and
 
    (b) payment (or evidence satisfactory to the Trustee, the Company and Subco
       of payment) of the taxes (if any) payable as contemplated by Section 5.9
       of this Agreement.
 
    If only a part of the Exchangeable Shares represented by any certificate or
certificates delivered to the Trustee are to be purchased by Subco under the
Exchange Right, a new certificate for the balance of such Exchangeable Shares
shall be issued to the Holder at the expense of the Company.
 
    5.7  DELIVERY OF EXCHANGEABLE SHARE CONSIDERATION; EFFECT OF
EXERCISE.  Promptly after receipt of the certificates duly endorsed for transfer
to Subco representing the Exchangeable Shares which the Holder desires Subco to
purchase under the Exchange Put Right or the Exchange Right, together with such
documents and instruments of transfer and a duly completed form of notice of
exercise of the Exchange Put Right or the Exchange Right (and payment of taxes,
if any, payable as contemplated by Section 5.9 hereof), the Trustee shall notify
Subco and the Company of its receipt of the same, which notice to Subco and the
Company shall constitute exercise of the Exchange Put Right or the Exchange
Right by the Trustee on behalf of the Holder of such Exchangeable Shares, and
Subco shall immediately thereafter deliver or cause to be delivered to the
Trustee, for delivery to the Holder of such Exchangeable Shares (or to such
other persons, if any, properly designated by such Holder), the Exchangeable
Share Consideration deliverable in connection with the exercise of the Exchange
Put Right or the Exchange Right (less any amounts withheld pursuant to Section
5.14 hereof); provided, however, that no such delivery shall be made unless and
until the Holder requesting the same shall have paid (or provided evidence
satisfactory to the Trustee, the Company and Subco of the payment of) the taxes
(if any) payable as contemplated by Section 5.9 of this Agreement. Immediately
upon the giving of notice by the Trustee to Subco and the Company of the
exercise of the Exchange Put Right or the Exchange Right, as provided in this
Section 5.7, (a) the closing of the transaction of purchase and sale
contemplated by the Exchange Put Right or the Exchange Right shall be deemed to
have occurred, (b) Subco shall be required to take all action necessary to
permit it to occur, including delivery to the Trustee of the relevant
Exchangeable Share Consideration, no later than the close of business on the
fifth Business Day following the receipt by the Trustee of notice, certificates
and other documents as aforesaid and (c) the Holder of such Exchangeable Shares
shall be deemed to have transferred to Subco all of its right, title and
interest in and to such Exchangeable Shares and the related interest in the
Trust Estate, shall cease to be a holder of such Exchangeable Shares and
 
 
<PAGE>
shall not be entitled to exercise any of the rights of a holder in respect
thereof, other than the right to receive his proportionate part of the total
purchase price therefor, unless such Exchangeable Share Consideration is not
delivered by Subco to the Trustee by the date specified above, in which case the
rights of the Holder shall remain unaffected until such Exchangeable Share
Consideration is delivered by Subco and any check included therein is paid.
Concurrently with such Holder ceasing to be a holder of Exchangeable Shares, the
Holder shall be considered and deemed for all purposes to be the holder of the
shares of Parent Common Stock delivered to it pursuant to the Exchange Put Right
or the Exchange Right. Notwithstanding the foregoing until the Exchangeable
Share Consideration is delivered to the Holder, the Holder shall be deemed to
still be a holder of the sold Exchangeable Shares for purposes of voting rights
with respect thereto under this Agreement.
 
    5.8  EXERCISE OF EXCHANGE RIGHT SUBSEQUENT TO RETRACTION.  In the event that
a Holder has exercised its right under Article 6 of the Exchangeable Share
Provisions to require the Company to redeem any or all of the Exchangeable
Shares held by the Holder (the "Retracted Shares") and is notified by the
Company pursuant to Section 6.6 of the Exchangeable Share Provisions that the
Company will not be permitted as a result of liquidity or solvency requirements
of applicable law to redeem all such Retracted Shares, subject to receipt by the
Trustee of written notice to that effect from the Company and provided that
Subco shall not have exercised the Retraction Call Right with respect to the
Retracted Shares and that the Holder has not revoked the retraction request
delivered by the Holder to the Company pursuant to Section 6.1 of the
Exchangeable Share Provisions, the retraction request will constitute and will
be deemed to constitute notice from the Holder to the Trustee instructing the
Trustee to exercise the Exchange Right with respect to those Retracted Shares
which the Company is unable to redeem. In any such event, the Company hereby
agrees with the Trustee and in favor of the Holder immediately to notify the
Trustee of such prohibition against the Company's redeeming all of the Retracted
Shares and immediately to forward or cause to be forwarded to the Trustee all
relevant materials delivered by the Holder to the Company or to the transfer
agent of the Exchangeable Shares (including without limitation a copy of the
retraction request delivered pursuant to Section 6.1 of the Exchangeable Share
Provisions) in connection with such proposed redemption of the Retracted Shares,
and the Trustee will thereupon exercise the Exchange Right with respect to the
Retracted Shares which the Company is not permitted to redeem and will require
Subco to purchase such shares in accordance with the provisions of this Article
5.
 
    5.9  STAMP OR OTHER TRANSFER TAXES.  Upon any sale of Exchangeable Shares to
Subco pursuant to the Exchange Put Right or the Exchange Right or any sale of
Exchangeable Shares to Parent or Subco pursuant to the Automatic Exchange
Rights, the share certificate or certificates representing Parent Common Stock
to be delivered in connection with the payment of the total purchase price
therefor shall be issued in the name of the Holder of the Exchangeable Shares so
sold or in such names as such Holder may otherwise direct in writing without
charge to the holder of the Exchangeable Shares so sold, provided, however, that
such Holder:
 
    (a) shall pay (and none of Parent, Subco, the Company or the Trustee shall
       be required to pay) any documentary, stamp, transfer or other taxes that
       may be payable in respect of any transfer involved in the issuance or
       delivery of such shares to a person other than such Holder, or
 
    (b) shall have established to the satisfaction of the Trustee, Subco, Parent
       (in the case of the sale of Exchangeable Shares to Parent pursuant to the
       Automatic Exchange Rights) and the Company that such taxes, if any, have
       been paid.
 
    5.10  NOTICE OF INSOLVENCY EVENT.  As soon as practicable following the
occurrence of an Insolvency Event or any event which with the giving of notice
or the passage of time or both would be an Insolvency Event, the Company and
Subco shall give written notice thereof to the Trustee. As soon as practicable
after receiving notice from the Company or Subco of the occurrence of an
Insolvency Event, the Trustee will mail to each Holder, at the expense of Subco,
a notice of such Insolvency Event in the form provided by Subco, which notice
shall contain a brief statement of the right of the Holders with respect to the
Exchange Right.
 
    5.11  QUALIFICATION OF PARENT COMMON STOCK.  Parent covenants that if any
shares of Parent Common Stock to be issued and delivered pursuant to the
Exchange Put Right, the Exchange Right or the Automatic Exchange Rights require
registration or qualification with or approval of or the filing of any document
including any prospectus or similar document, the taking of any proceeding with
or the obtaining of any order, ruling or consent from any governmental or
regulatory authority under any Canadian or United States federal, provincial
 
 
<PAGE>
or state law or regulation or pursuant to the rules and regulations of any
regulatory authority, or the fulfillment of any other legal requirement
(collectively, the "Applicable Laws") before such shares may be issued and
delivered by Parent or Subco to the initial holder thereof (other than the
Company) or in order that such shares may be freely traded thereafter (other
than contractual restrictions and any restrictions on transfer by reason of a
holder being a "CONTROL PERSON" of Parent for purposes of Canadian federal or
provincial securities law or an "AFFILIATE" of Parent or the Company for
purposes of United States federal or state securities law), Parent will in good
faith expeditiously take all such actions and do all such things as are
necessary to cause such shares of Parent Common Stock to be and remain duly
registered, qualified or approved. Parent represents and warrants that it has in
good faith taken all actions and done all things as are necessary under
Applicable Laws as they exist on the date hereof to cause the shares of Parent
Common Stock to be issued and delivered pursuant to the Exchange Put Right, the
Exchange Right and the Automatic Exchange Rights and to be freely tradeable
thereafter (other than contractual restrictions and restrictions on transfer by
reason of a holder being a "CONTROL PERSON" of Parent for the purposes of
Canadian federal and provincial securities law or an "AFFILIATE" of Parent or
the Company for the purposes of United States federal or state securities law).
Parent will in good faith expeditiously take all such actions and do all such
things as are necessary to cause all shares of Parent Common Stock to be
delivered pursuant to the Exchange Put Right, the Exchange Right or the
Automatic Exchange Rights to be listed, quoted or posted for trading on all
stock exchanges and quotation systems on which such shares are listed, quoted or
posted for trading at such time.
 
    5.12  PARENT COMMON STOCK.  Parent hereby represents, warrants and covenants
that the Parent Common Stock issuable and deliverable as described herein will
be duly authorized and validly issued as fully paid and non-assessable.
 
    5.13  AUTOMATIC EXCHANGE ON LIQUIDATION OF PARENT.
 
    (a) Parent will give the Trustee written notice of each of the following
events at the time set forth below:
 
    (i) in the event of any determination by the board of directors of Parent to
        institute voluntary liquidation, dissolution or winding-up proceedings
        with respect to Parent or to effect any other distribution of assets of
        Parent among its stockholders for the purpose of winding up its affairs,
        at least 60 days prior to the proposed effective date of such
        liquidation, dissolution, winding-up or other distribution; and
 
    (ii) as soon as practicable following the earlier of:
 
       (A) receipt by Parent of notice of and
 
       (B) Parent's otherwise becoming aware of any threatened or instituted
           claim, suit, petition or other proceedings with respect to the
           involuntary liquidation, dissolution or winding-up of Parent or to
           effect any other distribution of assets of Parent among its
           stockholders for the purpose of winding up its affairs, in each case
           where Parent has failed to contest in good faith any such proceeding
           commenced in respect of Parent within 30 days of becoming aware
           thereof.
 
    (b) Immediately following receipt by the Trustee from Parent of notice of
any event (a "Liquidation Event") contemplated by Section 5.13(a)(i) or
5.13(a)(ii) above, the Trustee will give notice thereof to the Holders. Such
notice shall include a brief description of the automatic exchange of
Exchangeable Shares for shares of Parent Common Stock provided for in Section
5.13(c).
 
    (c) In order that the Holders will be able to participate on a pro rata
basis with the holders of Parent Common Stock in the distribution of assets of
Parent in connection with a Liquidation Event, immediately prior to the
effective time (the "Liquidation Event Effective Time") of a Liquidation Event,
all of the then outstanding Exchangeable Shares shall be automatically exchanged
for shares of Parent Common Stock. To effect such automatic exchange, Parent or
Subco, as determined by Parent and notified in writing to the Trustee, or upon
failure of such notice, Parent, shall be deemed to have purchased each
Exchangeable Share outstanding immediately prior to the Liquidation Event
Effective Time and held by Holders, and each Holder shall be deemed to have sold
the Exchangeable Shares held by it at such time, for a purchase price per share
equal to the Exchangeable Share Price applicable at such time. In connection
with such automatic exchange, Parent will provide to the Trustee an Officer's
Certificate setting forth the calculation of the purchase price for each
Exchangeable Share.
 
 
<PAGE>
    (d) The closing of the transaction of purchase and sale contemplated by
Section 5.13(c) above shall be deemed to have occurred immediately prior to the
Liquidation Event Effective Time, and each Holder of Exchangeable Shares shall
be deemed to have transferred to Parent or Subco, as the case may be, all of the
Holder's right, title and interest in and to such Exchangeable Shares and the
related interest in the Trust Estate and shall cease to be a holder of such
Exchangeable Shares, and Parent or Subco, as the case may be, shall deliver to
the Holder the Exchangeable Share Consideration deliverable upon the automatic
exchange of Exchangeable Shares (less any amounts withheld pursuant to Section
5.14 hereof). Concurrently with such Holder's ceasing to be a holder of
Exchangeable Shares, the Holder shall be considered and deemed for all purposes
to be the holder of the shares of Parent Common Stock delivered to it pursuant
to the automatic exchange of Exchangeable Shares for Parent Common Stock, and
the certificates held by the Holder previously representing the Exchangeable
Shares exchanged by the Holder with Parent or Subco, as the case may be,
pursuant to such automatic exchange shall thereafter be deemed to represent the
shares of Parent Common Stock delivered to the Holder pursuant to such automatic
exchange. Upon the request of a Holder and the surrender by the Holder of
Exchangeable Share certificates deemed to represent shares of Parent Common
Stock, duly endorsed in blank and accompanied by such instruments of transfer as
Parent or Subco, as the case may be, may reasonably require, Parent or Subco, as
the case may be, shall deliver or cause to be delivered to the Holder
certificates representing the shares of Parent Common Stock of which the Holder
is the holder. Notwithstanding the foregoing, until each Holder is actually
entered on the register of holders of Parent Common Stock, such Holder shall be
deemed to still be a holder of the transferred Exchangeable Shares for purposes
of all voting rights with respect thereto under this Agreement.
 
    5.14  WITHHOLDING RIGHTS.  Parent, Subco and the Trustee shall be entitled
to deduct and withhold from any consideration otherwise payable under this
Agreement to any holder of Exchangeable Shares or Parent Common Stock such
amounts as Parent, Subco or the Trustee is required or permitted to deduct and
withhold with respect to such payment under the Income Tax Act (Canada), the
United States Internal Revenue Code of 1986 or any provision of provincial,
state, local or foreign tax law, in each case as amended or succeeded. To the
extent that amounts are so withheld, such withheld amounts shall be treated for
all purposes as having been paid to the holder of the shares in respect of which
such deduction and withholding was made, provided that such withheld amounts are
actually remitted to the appropriate taxing authority. To the extent that the
amount so required or permitted to be deducted or withheld from any payment to a
holder exceeds the cash portion of the consideration otherwise payable to the
holder, Parent, Subco and the Trustee are hereby authorized to sell or otherwise
dispose of such portion of the consideration as is necessary to provide
sufficient funds to Parent, Subco or the Trustee, as the case may be, to enable
it to comply with such deduction or withholding requirement and Parent, Subco or
the Trustee shall notify the holder thereof and remit to such holder any
unapplied balance of the net proceeds of such sale.
 
                                   ARTICLE 6
            RESTRICTIONS ON ISSUANCE OF PARENT SPECIAL VOTING STOCK
 
    During the term of this Agreement, Parent will not, without the consent of
the holders at the relevant time of the Exchangeable Shares given in accordance
with Article 10 of the Exchangeable Share Provisions, issue any shares of Parent
Special Voting Stock in addition to the Voting Share.
 
                                   ARTICLE 7
                             CONCERNING THE TRUSTEE
 
    7.1  POWERS AND DUTIES OF THE TRUSTEE.  The rights, powers and authorities
of the Trustee under this Agreement, in its capacity as trustee of the Trust,
shall include:
 
    (a) receipt and deposit of the Voting Share from Parent as trustee for and
       on behalf of the Holders in accordance with the provisions of this
       Agreement;
 
    (b) granting proxies and distributing materials to Holders as provided in
       this Agreement;
 
    (c) voting the Holder Votes in accordance with the provisions of this
       Agreement;
 
 
<PAGE>
    (d) receiving the grant of the Exchange Put Right and the Exchange Right
       from Subco and receiving the grant of the Automatic Exchange Rights from
       Parent and Subco as trustee for and on behalf of the Holders in
       accordance with the provisions of this Agreement;
 
    (e) exercising the Exchange Put Right and the Exchange Right and enforcing
       the benefit of the Automatic Exchange Rights, in each case in accordance
       with the provisions of this Agreement, and in connection therewith
       receiving from Holders Exchangeable Shares and other requisite documents
       and distributing to such Holders the shares of Parent Common Stock and
       checks, if any, to which such Holders are entitled upon the exercise of
       the Exchange Put Right and the Exchange Right or pursuant to the
       Automatic Exchange Rights, as the case may be;
 
    (f) holding title to the Trust Estate;
 
    (g) investing any moneys forming, from time to time, a part of the Trust
       Estate as provided in this Agreement;
 
    (h) taking action at the direction of a Holder or Holders to enforce the
       obligations of Parent, Subco and the Company under this Agreement; and
 
    (i) taking such other actions and doing such other things as are
       specifically provided in this Agreement.
 
    In the exercise of such rights, powers and authorities the Trustee shall
have (and is granted) such incidental and additional rights, powers and
authority not in conflict with any of the provisions of this Agreement as the
Trustee, acting in good faith and in the reasonable exercise of its discretion,
may deem necessary, appropriate or desirable to effect the purpose of the Trust.
Any exercise of such discretionary rights, powers and authorities by the Trustee
shall be final, conclusive and binding upon all persons. The Trustee in
exercising its rights, powers, duties and authorities hereunder shall act
honestly and in good faith with a view to the best interests of the Holders and
shall exercise the care, diligence and skill that a reasonably prudent trustee
would exercise in comparable circumstances.
 
    7.2  NO CONFLICT OF INTEREST.  The Trustee represents to the Company, Parent
and Subco that at the date of execution and delivery of this Agreement there
exists no material conflict of interest in the role of the Trustee as a
fiduciary hereunder and the role of the Trustee in any other capacity. The
Trustee shall within 60 days after it becomes aware that such a material
conflict of interest exists, either eliminate such material conflict of interest
or resign in the manner and with the effect specified in Article 10 hereof. If,
notwithstanding the foregoing provisions of this Section 7.2, the Trustee has
such a material conflict of interest, the validity and enforceability of this
Agreement shall not be affected in any manner whatsoever by reason only of the
existence of such material conflict of interest. If the Trustee contravenes the
foregoing provisions of this Section 7.2, any interested party may apply to the
Ontario Court of Justice (General Division) for an order that the Trustee be
replaced as trustee hereunder.

and Subco irrevocably authorize the Trustee, from time to time, to:
 
    (a) consult, communicate and otherwise deal with the respective registrars
       and transfer agents, and with any such subsequent registrar or transfer
       agent, of the Exchangeable Shares and Parent Common Stock; and
 
    (b) requisition, from time to time,
 
        (i) from any such registrar or transfer agent any information readily
            available from the records maintained by it which the Trustee may
            reasonably require for the discharge of its duties and
            responsibilities under this Agreement and
 
        (ii) from the transfer agent of Parent Common Stock, and any subsequent
             transfer agent of such shares, to complete the exercise from time
             to time of the Exchange Put Right, the Exchange Right and the
             Automatic Exchange Rights in the manner specified in Article 5
             hereof, the share certificates issuable upon such exercise.
 
 
<PAGE>
    The Company, Parent and Subco irrevocably authorize their respective
registrars and transfer agents to comply with all such requests. Parent
covenants that it will supply its transfer agent with duly executed share
certificates for the purpose of completing the exercise from time to time of the
Exchange Put Right, the Exchange Right and the Automatic Exchange Rights, in
each case pursuant to Article 5 hereof.
 
    7.4  BOOKS AND RECORDS.  The Trustee shall keep available for inspection by
Parent, Subco and the Company, at the Trustee's principal trust office in
Toronto, Ontario, correct and complete books and records of account relating to
the Trustee's actions under this Agreement, including without limitation, all
information relating to mailings and instructions to and from Holders and all
transactions pursuant to the Voting Rights, the Exchange Put Right, the Exchange
Right and the Automatic Exchange Rights for the term of this Agreement. On or
before March 31, 2000, and on or before March 31 in every year thereafter, so
long as the Voting Share is on deposit with the Trustee, the Trustee shall
transmit to Parent and the Company a brief report, dated as of the preceding
December 31, with respect to:

    (b) the number of exercises of the Exchange Put Right and the Exchange
       Right, if any, and the aggregate number of Exchangeable Shares received
       by the Trustee on behalf of Holders in consideration of the issue and
       delivery by Parent of shares of Parent Common Stock in connection with
       the Exchange Put Right and the Exchange Right, during the calendar year
       ended on such date; and
 
    (c) all other actions taken by the Trustee in the performance of its duties
       under this Agreement which it had not previously reported.
 
    7.5  INCOME TAX RETURNS AND REPORTS.  The Trustee shall to the extent
necessary, prepare and file on behalf of the Trust appropriate United States and
Canadian income tax returns and any other returns or reports as may be required
by applicable law or pursuant to the rules and regulations of any securities
exchange or other trading system through which the Exchangeable Shares are
traded.
 
    7.6  INDEMNIFICATION PRIOR TO CERTAIN ACTIONS BY TRUSTEE.  The Trustee shall
exercise any or all of the rights, duties, powers or authorities vested in it by
this Agreement at the request, order or direction of any Holder upon such
Holder's furnishing to the Trustee reasonable funding, security and indemnity
against the costs, expenses and liabilities which may be incurred by the Trustee
therein or thereby; provided that no Holder shall be obligated to furnish to the
Trustee any such funding, security or indemnity in connection with the exercise
by the Trustee of any of its rights, duties, powers and authorities with respect
to the Voting Share pursuant to Article 4 hereof, subject to Section 7.15
hereof, and with respect to the Exchange Put Right and the Exchange Right
pursuant to Article 5 hereof, subject to Section 7.15 hereof, and with respect
to the Automatic Exchange Rights pursuant to Article 5 hereof. None of the
provisions contained in this Agreement shall require the Trustee to expend or
risk its own funds or otherwise incur financial liability in the exercise of any
of its rights, powers, duties or authorities unless funded, given funds,
security and indemnified as aforesaid.
 
    7.7  ACTIONS BY HOLDERS.  No Holder shall have the right to institute any
action, suit or proceeding or to exercise any other remedy authorized by this
Agreement for the purpose of enforcing any of its rights or for the execution of
any trust or power hereunder unless the Holder has requested the Trustee to take
or institute such action, suit or proceeding and furnished the Trustee with the
funding, security and indemnity referred to in Section 7.6 hereof and the
Trustee shall have failed to act within a reasonable time thereafter. In such
case, but not otherwise, the Holder shall be entitled to take proceedings in any
court of competent jurisdiction such as the Trustee might have taken; it being
understood and intended that no one or more Holders shall have any right in any
manner whatsoever to affect, disturb or prejudice the rights hereby created by
any such action, or to enforce any right hereunder or under the Voting Rights,
the Exchange Put Right, the Exchange Right or the Automatic Exchange Rights,
except subject to the conditions and in the manner herein provided, and that all
powers and trusts hereunder shall be exercised and all proceedings at law shall
be instituted, had and maintained by the Trustee, except only as herein
provided, and in any event for the equal benefit of all Holders.
 
    7.8  RELIANCE UPON DECLARATIONS.  The Trustee shall not be considered to be
in contravention of any of its rights, powers, duties and authorities hereunder
if, when required, it acts and relies in good faith upon lists, mailing labels,
notices, statutory declarations, certificates, opinions, reports or other papers
or documents furnished pursuant to the provisions hereof or required by the
Trustee to be furnished to it in the exercise of its
 
 
<PAGE>
rights, powers, duties and authorities hereunder, and such lists, mailing
labels, notices, statutory declarations, certificates, opinions, reports or
other papers or documents comply with the provisions of Section 7.9 hereof, if
applicable, and with any other applicable provisions of this Agreement.
 
    7.9  EVIDENCE AND AUTHORITY TO TRUSTEE.  The Company, Parent and Subco shall
furnish to the Trustee evidence of compliance with the conditions provided for
in this Agreement relating to any action or step required or permitted to be
taken by any of them or the Trustee under this Agreement or as a result of any

respect of the Voting Rights or the Exchange Put Right, the Exchange Right or
the Automatic Exchange Rights and the taking of any other action to be taken by

       furnished to the Trustee in accordance with the terms of this Section
       7.9; or
 
    (b) the Trustee, in the exercise of its rights, powers, duties and
       authorities under this Agreement, gives the Company, Parent or Subco

except as otherwise specifically provided herein, such evidence may consist of a
report or opinion of any solicitor, auditor, accountant, appraiser, valuer,
engineer or other expert or any other person whose qualifications give authority
to a statement made by such person, provided that if such report or opinion is
furnished by a director, officer or employee of the Company, Parent or Subco it
shall be in the form of an Officer's Certificate or a statutory declaration.
 
    Each statutory declaration, Officer's Certificate, opinion or report
furnished to the Trustee as evidence of compliance with a condition provided for

       and may employ such assistants as may be necessary to the proper
       determination and discharge of its powers and duties and determination of
       its rights hereunder and may pay proper and reasonable compensation for
       all such legal and other advice or assistance as aforesaid; and
 
    (b) employ such agents and other assistants as it may reasonably require for
       the proper determination and discharge of its powers and duties
       hereunder, and may pay reasonable remuneration for all services performed
       for it (and shall be entitled to receive reasonable remuneration for all
       services performed by it) in the discharge of the trusts hereof and

    7.11  INVESTMENT OF MONEYS HELD BY TRUSTEE.  Unless otherwise provided in
this Agreement, any moneys held by or on behalf of the Trustee which under the
terms of this Agreement may or ought to be invested or which may be on deposit
with the Trustee or which may be in the hands of the Trustee, may be invested
and reinvested in the name or under the control of the Trustee in securities in
which, under the laws of the Province of Ontario, trustees are authorized to
invest trust moneys; provided that such securities are stated to mature within
two years after their purchase by the Trustee, and the Trustee shall so invest
such moneys on the written direction of the Company. Pending the investment of
any moneys as hereinbefore provided, such moneys may be deposited in the name of
the Trustee in any chartered bank in Canada or, with the consent of the Company,
in the deposit department of the Trustee or any other loan or trust company
authorized to accept deposits under the laws of Canada or any province thereof
at the rate of interest then current on similar deposits.
 
    7.12  TRUSTEE NOT REQUIRED TO GIVE SECURITY.  The Trustee shall not be
required to give any bond or security in respect of the execution of the trusts,
rights, duties, powers and authorities of this Agreement or otherwise in respect
of the premises.
 
    7.13  TRUSTEE NOT BOUND TO ACT ON REQUEST.  Except as otherwise specifically
provided in this Agreement, the Trustee shall not be bound to act in accordance
with any direction or request of the Company, Parent or Subco or of the
directors thereof until a duly authenticated copy of the instrument or
resolution containing such direction or request shall have been delivered to the
Trustee, and the Trustee shall be empowered to act and rely upon any such copy
purporting to be authenticated and believed by the Trustee to be genuine.
 
    7.14  AUTHORITY TO CARRY ON BUSINESS.  The Trustee represents to the
Company, Parent and Subco that at the date of execution and delivery by it of
this Agreement it is authorized to carry on the business of a trust company in
each of the Provinces of Canada but if, notwithstanding the provisions of this
Section 7.14, it ceases to be so authorized to carry on business, the validity
and enforceability of this Agreement and the Voting Rights, the Exchange Put
Right, the Exchange Right and the Automatic Exchange Rights shall not be
affected in any manner whatsoever by reason only of such event; provided,
however, the Trustee shall within 60 days after ceasing to be authorized to
carry on the business of a trust company in any Province of Canada, either
become so authorized or resign in the manner and with the effect specified in
Article 10 hereof.
 
    7.15  CONFLICTING CLAIMS.  If conflicting claims or demands are made or
asserted with respect to any interest of any Holder in any Exchangeable Shares,
including any disagreement between the heirs, representatives, successors or
assigns succeeding to all or any part of the interest of any Holder in any
Exchangeable Shares resulting in conflicting claims or demands being made in
connection with such interest, then the Trustee shall be entitled, at its sole
discretion, to refuse to recognize or to comply with any such claim or demand.
In so refusing, the Trustee may elect not to exercise any Voting Rights,
Exchange Put Right, Exchange Right or Automatic Exchange Rights subject to such
conflicting claims or demands and, in so doing, the Trustee shall not be or
become liable to any person on account of such election or its failure or
refusal to comply with any such conflicting claims or demands. The Trustee shall
be entitled to continue to refrain from acting and to refuse to act until:
 
    (a) the rights of all adverse claimants with respect to the Voting Rights,
       Exchange Put Right, Exchange Right or Automatic Exchange Rights subject
       to such conflicting claims or demands have been adjudicated by a final
       judgment of a court of competent jurisdiction; or
 
    (b) all differences with respect to the Voting Rights, Exchange Put Right,
       Exchange Right or Automatic Exchange Rights subject to such conflicting
       claims or demands have been conclusively settled by a valid written
       agreement binding on all such adverse claimants, and the Trustee shall
       have been furnished with an executed copy of such agreement.
 
    If the Trustee elects to recognize any claim or comply with any demand made
by any such adverse claimant, it may in its discretion require such claimant to
furnish such surety bond or other security satisfactory to the Trustee as it
shall deem appropriate fully to indemnity it as between all conflicting claims
or demands.

                                  COMPENSATION
 
    Parent, Subco and the Company jointly and severally agree to pay to the
Trustee reasonable compensation for all of the services rendered by it under
this Agreement and will reimburse the Trustee for all reasonable expenses
(including taxes other than taxes based on the net income of the Trustee) and
disbursements, including the cost and expense of any suit or litigation of any
character and any proceedings before any governmental agency, reasonably
incurred by the Trustee in connection with its rights and duties under this
Agreement; provided that Parent, Subco and the Company shall have no obligation
to reimburse the Trustee for any expenses or disbursements paid, incurred or
suffered by the Trustee in any suit or litigation in which the Trustee is
determined to have acted fraudulently or in bad faith or with negligence,
recklessness or willful misconduct.
 
                                   ARTICLE 9
                  INDEMNIFICATION AND LIMITATION OF LIABILITY
 
    9.1  INDEMNIFICATION OF THE TRUSTEE.  Parent, Subco and the Company jointly
and severally agree to indemnity and hold harmless the Trustee and each of its
directors, officers and agents appointed and acting in accordance with this
Agreement (collectively, the "Indemnified Parties") against all claims, losses,
damages, costs, penalties, fines and reasonable expenses (including reasonable
expenses of the Trustee's legal counsel) which, without fraud, negligence,
recklessness, willful misconduct or bad faith on the part of such Indemnified
Party, may be paid, incurred or suffered by the Indemnified Party by reason of
or as a result of the Trustee's acceptance or administration of the Trust, its
compliance with its duties set forth in this Agreement, or any written or oral
instructions delivered to the Trustee by Parent, Subco or the Company pursuant
hereto. In no case shall Parent, Subco or the Company be liable under this
indemnity for any claim against any of the Indemnified Parties unless Parent,
Subco and the Company shall be notified by the Trustee of the written assertion
of a claim or of any action commenced against the Indemnified Parties, promptly
after any of the Indemnified Parties shall have received any such written
assertion of a claim or shall have been served with a summons or other first
legal process giving information as to the nature and basis of the claim.
Subject to (ii) below, Parent, Subco and the Company shall be entitled to
participate at their own expense in the defense and, if Parent, Subco or the
Company so elect at any time after receipt of such notice, any of them may
assume the defense of any suit brought to enforce any such claim. The Trustee
shall have the right to employ separate counsel in any such suit and participate
in the defense thereof, but the fees and expenses of such counsel shall be at
the expense of the Trustee unless: (i) the employment of such counsel has been
authorized by Parent, Subco or the Company; or (ii) the named parties to any
such suit include both the Trustee and Parent, Subco or the Company and the
Trustee shall have been advised by counsel acceptable to Parent, Subco or the
Company that there may be one or more legal defenses available to the Trustee
that are different from or in addition to those available to Parent, Subco or
the Company and that, in the judgement of such counsel, would present a conflict
of interest were a joint representation to be undertaken (in which case Parent,
Subco and the Company shall not have the right to assume the defense of such
suit on behalf of the Trustee, but shall be liable to pay the reasonable fees
and expenses of counsel for the Trustee).
 
    9.2  LIMITATION OF LIABILITY.  The Trustee shall not be held liable for any
loss which may occur by reason of depreciation of the value of any part of the
Trust Estate or any loss incurred on any investment of funds pursuant to this
Agreement, except to the extent that such loss is attributable to the fraud,
negligence, recklessness, willful misconduct or bad faith on the part of the
Trustee.
 
                                   ARTICLE 10
                               CHANGE OF TRUSTEE
 
    10.1  RESIGNATION.  The Trustee, or any trustee hereafter appointed, may at
any time resign by giving written notice of such resignation to Parent, Subco
and the Company specifying the date on which it desires to resign, provided that
such notice shall never be given less than 60 days before such desired
resignation date unless Parent, Subco and the Company otherwise agree and
provided further that such resignation shall not take effect until the date of
the appointment of a successor trustee and the acceptance of such appointment by
the
 
 
<PAGE>
successor trustee. Upon receiving such notice of resignation, Parent, Subco and
the Company shall promptly appoint a successor trustee by written instrument in
duplicate, one copy of which shall be delivered to the resigning trustee and one
copy to the successor trustee. Failing acceptance by a successor trustee, a
successor trustee may be appointed by an order of the Ontario Court of Justice
(General Division) upon application of one or more of the parties hereto.
 
    10.2  REMOVAL.  The Trustee, or any trustee hereafter appointed, may be
removed with or without cause, at any time on not less than 30 days' prior
notice by written instrument executed by Parent, Subco and the Company, in
duplicate, one copy of which shall be delivered to the trustee so removed and
one copy to the successor trustee, provided that, in connection with such
removal, provision is made for a replacement trustee similar to that
contemplated in Section 10.1.
 
    10.3  SUCCESSOR TRUSTEE.  Any successor trustee appointed as provided under
this Agreement shall execute, acknowledge and deliver to Parent, Subco and the
Company and to its predecessor trustee an instrument accepting such appointment.
Thereupon the resignation or removal of the predecessor trustee shall become
effective and such successor trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, duties and
obligations of its predecessor under this Agreement, with like effect as if
originally named as trustee in this Agreement. However, on the written request
of Parent, Subco and the Company or of the successor trustee, the trustee
ceasing to act shall, upon payment of any amounts then due it pursuant to the
provisions of this Agreement, execute and deliver an instrument transferring to
such successor trustee all the rights and powers of the trustee so ceasing to
act. Upon the request of any such successor trustee, Parent, Subco, the Company
and such predecessor trustee shall execute any and all instruments in writing
for more fully and certainly vesting in and confirming to such successor trustee
all such rights and powers.
 
    10.4  NOTICE OF SUCCESSOR TRUSTEE.  Upon acceptance of appointment by a
successor trustee as provided herein, Parent, Subco and the Company shall cause
to be mailed notice of the succession of such trustee hereunder to each Holder
specified in a List. If Parent, Subco or the Company shall fail to cause such
notice to be mailed within 10 days after acceptance of appointment by the
successor trustee, the successor trustee shall cause such notice to be mailed at
the expense of Parent, Subco and the Company.
 
                                   ARTICLE 11
                               PARENT SUCCESSORS
 
    11.1  CERTAIN REQUIREMENTS IN RESPECT OF COMBINATION, ETC.  Parent shall not
enter into any transaction (whether by way of reconstruction, reorganization,
consolidation, merger, transfer, sale, lease or otherwise) whereby all or
substantially all of its undertaking, property and assets would become the
property of any other Person or, in the case of a merger, of the continuing
corporation resulting therefrom, but may do so if:
 
    (a) such other Person or continuing corporation (the "Parent Successor"), by
       operation of law, becomes, without more, bound by the terms and
       provisions of this Agreement or, if not so bound, executes, prior to or
       contemporaneously with the consummation of such transaction an Agreement
       supplemental hereto and such other instruments (if any) as are
       satisfactory to the Trustee, acting reasonably, and in the opinion of
       legal counsel to the Trustee are necessary or advisable to evidence the
       assumption by the Parent Successor of liability for all moneys payable
       and property deliverable hereunder, the covenant of such Parent Successor
       to pay and deliver or cause to be delivered the same and its agreement to
       observe and perform all the covenants and obligations of Parent under
       this Agreement; and
 
    (b) such transaction shall, to the satisfaction of the Trustee and in the
       opinion of legal counsel to the Trustee, be upon such terms which
       substantially preserve and do not impair in any material respect any of
       the rights, duties, powers and authorities of the Trustee or of the
       Holders hereunder.
 
    11.2  VESTING OF POWERS IN PARENT SUCCESSOR.  Whenever the conditions of
Section 11.1 hereof have been duly observed and performed, the Trustee, if
required by Section 11.1 hereof, the Parent Successor, Subco and the Company
shall execute and deliver the supplemental agreement provided for in Article 12
hereof, and thereupon the Parent Successor shall possess and from time to time
may exercise each and every right and power of Parent under this Agreement in
the name of Parent or otherwise and any act or proceeding by any provision
 
 
<PAGE>
of this Agreement required to be done or performed by the board of directors of
Parent or any officers of Parent may be done and performed with like force and
effect by the directors or officers of such Parent Successor.
 
    11.3  WHOLLY-OWNED SUBSIDIARIES.  Nothing herein shall be construed as
preventing the amalgamation or merger of any wholly-owned subsidiary of Parent
with or into Parent or the winding-up, liquidation or dissolution of any
wholly-owned subsidiary of Parent provided that all of the assets of such
subsidiary are transferred to Parent or another wholly-owned subsidiary of
Parent, and any such transactions are expressly permitted by this Article 11.
 
                                   ARTICLE 12
                     AMENDMENTS AND SUPPLEMENTAL AGREEMENTS

Agreement may not be amended, modified or waived except by an agreement in
writing executed by the Company, Subco, Parent and the Trustee and approved by

       protection of the Holders hereunder;
 
    (b) making such amendments or modifications not inconsistent with this
       Agreement as may be necessary or desirable with respect to matters or
       questions which, in the opinion of the board of directors of each of
       Parent, Subco and the Company and in the opinion of the Trustee and its
       counsel, having in mind the best interests of the Holders as a whole, it
       may be expedient to make, provided that such boards of directors and the
       Trustee and its counsel shall be of the opinion that such amendments and
       modifications will not be prejudicial to the interests of the Holders as
       a whole; or
 
    (c) making such changes or corrections which, on the advice of counsel to
       the Company, Subco, Parent and the Trustee, are required for the purpose
       of curing or correcting any ambiguity or defect or inconsistent provision
       or clerical omission or mistake or manifest error; provided that the
       Trustee and its counsel and the board of directors of each of the
       Company, Subco and Parent shall be of the opinion that such changes or
       corrections will not be prejudicial to the interests of the Holders as a

or Subco, shall call a meeting or meetings of the Holders for the purpose of

    2.1  COVENANTS OF PARENT AND SUBCO REGARDING EXCHANGEABLE SHARES.  So long
as any Exchangeable Shares are outstanding:
 
    (a) Parent will not declare or pay any dividend on Parent Common Stock
       unless (i) the Company will have sufficient assets, funds and other
       property available to enable the due declaration and the due and punctual
       payment in accordance with applicable law of an equivalent dividend on
       the Exchangeable Shares and (ii) subsection 2.1(b) shall be complied with
       in connection with such dividend;

       dividend on the Exchangeable Shares and, when such dividend is paid on
       Parent Common Stock, cause the Company to pay simultaneously therewith
       such equivalent dividend on the Exchangeable Shares, in each case in
       accordance with the Exchangeable Share Provisions;
 
    (c) Parent will advise Subco and the Company sufficiently in advance of the
       declaration by Parent of any dividend on Parent Common Stock and take all
       such other actions as are necessary, in cooperation with Subco and the
       Company, to ensure that the respective declaration date, record date and
       payment date for a dividend on the Exchangeable Shares shall be the same
       as the record date, declaration date and payment date for the
       corresponding dividend on Parent Common Stock and that such dividend on
       the Exchangeable Shares will correspond with any requirement of the
       principal stock exchange on which the Exchangeable Shares are listed;

       Parent Common Stock is not less than ten Business Days after the

    (e) Parent and Subco will take all such actions and do all such things as
       are reasonably necessary or desirable to enable and permit the Company,
       in accordance with applicable law, to pay and otherwise perform its
       obligations with respect to the satisfaction of the Liquidation Amount,
       the Retraction Price or the Redemption Price in respect of each issued
       and outstanding Exchangeable Share upon the liquidation, dissolution or
       winding-up of the Company, the delivery of a Retraction Request by a
       holder of Exchangeable Shares or a redemption of Exchangeable Shares by
       the Company, as the case may be, including, without limitation, all such
       actions and all such things as are reasonably necessary or desirable to
       enable and permit the Company to cause to be delivered Parent Common
       Stock to the holders of Exchangeable Shares in accordance with the
       provisions of Article 5, 6 or 7, as the case may be, of the Exchangeable
       Share Provisions; and
 
    (f) Parent will take all such actions and do all such things as are
       reasonably necessary or desirable to enable and permit Subco, in
       accordance with applicable law, to perform its obligations arising upon
       (i) the exercise by Subco of the Liquidation Call Right, the Retraction
       Call Right or the Redemption Call Right or (ii) the exercise by a holder
       of Exchangeable Shares of such holder's Exchange Put Right or Exchange
       Right or (iii) the automatic exchange of a holder's Exchangeable Shares
       in accordance with the rights set forth in Section 5.13 of the Voting and
       Exchange Trust Agreement (the "Automatic Exchange Rights"), including,
       without limitation, all such actions and all such things as are
       reasonably necessary or desirable to enable and permit Subco to cause
       Parent Common Stock to be delivered to
 
                                      
<PAGE>
       the holders of Exchangeable Shares in accordance with the Exchangeable
       Share Provisions and the Voting and Exchange Trust Agreement.
 
    2.2  SEGREGATION OF FUNDS.  Parent and Subco will cause the Company to
deposit a sufficient amount of funds in a separate account and segregate a
sufficient amount of such assets and other property as is necessary to enable
the Company to pay or otherwise satisfy the applicable dividends, Liquidation
Amount, Retraction Price or Redemption Price, in each case for the benefit of
holders from time to time of the Exchangeable Shares, and the Company will use
such funds, assets and other property so segregated exclusively for the payment
of dividends and the payment or other satisfaction of the Liquidation Amount,
the Retraction Price or the Redemption Price, as applicable, net of any
corresponding withholding tax obligations and for the remittance of such
withholding tax obligations.
 
    2.3  RESERVATION OF SHARES OF PARENT COMMON STOCK.  Parent hereby
represents, warrants and covenants that it has irrevocably reserved for issuance
and will at all times keep available, free from preemptive and other rights, out
of its authorized and unissued capital stock such number of shares of Parent
Common Stock (or other shares or securities into which Parent Common Stock may
be reclassified or changed as contemplated by section 2.7 hereof) (a) as is
equal to the sum of (i) the number of Exchangeable Shares issued and outstanding
from time to time and (ii) the number of Exchangeable Shares issuable upon the
exercise of all rights to acquire Exchangeable Shares outstanding from time to
time and (b) as are now and may hereafter be required to enable and permit
Parent to meet its obligations hereunder, under the Voting and Exchange Trust
Agreement and under any other security or commitment pursuant to which Parent
may now or hereafter be required to issue Parent Common Stock, to enable and
permit Subco to meet its respective obligations or exercise its rights

Share Provisions and to enable and permit the Company to meet its respective

Agreement, (b) assist Subco to comply with its obligations hereunder, under the

and (c) permit Subco to exercise its rights under the Exchangeable Share
Provisions, the Company will give or cause the Transfer Agent to give Subco and
Parent notice of each of the following events at the time set forth below:
 
    (i) immediately, in the event of any determination by the Board of Directors
        of the Company to take any action which would require a vote of the
        holders of Exchangeable Shares for approval;
 
    (ii) immediately, upon the earlier of (A) receipt by the Company of notice
         of, and (B) the Company otherwise becoming aware of, any threatened or
         instituted claim, suit, petition or other proceedings with respect to
         the involuntary liquidation, dissolution or winding-up of the Company
         or to effect any other distribution of the assets of the Company among
         its shareholders for the purpose of winding-up its affairs;
 
   (iii) immediately, upon receipt by the Company of a Retraction Request;
 
    (iv) at least 130 days prior to any Automatic Redemption Date determined by

         Provisions; and
 
    (v) as soon as practicable upon the issuance by the Company of any
        Exchangeable Shares or rights to acquire Exchangeable Shares (other than
        the issuance of Exchangeable Shares and rights to acquire Exchangeable
        Shares in exchange for outstanding Common Shares pursuant to the
        Arrangement).
 
    2.5  DELIVERY OF SHARES OF PARENT COMMON STOCK.  In furtherance of its
obligations hereunder, upon notice from the Company or Subco of any event which
requires the Company or Subco to cause to be delivered shares of Parent Common
Stock to any holder of Exchangeable Shares, Parent shall forthwith issue and
deliver or cause to be delivered to the Company or Subco the requisite shares of
Parent Common Stock to be received by, and issued to the order of, the former
holder of the surrendered Exchangeable Shares, as the Company or Subco shall
direct. All such shares of Parent Common Stock shall be duly issued as fully
paid and non-assessable. In consideration of the issuance and delivery of each
such share of Parent Common Stock, the Company or Subco,
 
                                      
<PAGE>
as the case may be, shall issue to Parent, or as Parent shall direct, shares or
other securities having equivalent value.
 
    2.6  QUALIFICATION OF SHARES OF PARENT COMMON STOCK.  If any shares of
Parent Common Stock (or other shares or securities into which Parent Common
Stock may be reclassified or changed as contemplated by Section 2.7 hereof) to
be issued and delivered hereunder require registration or qualification with or
approval of or the filing of any document including any prospectus or similar
document, the taking of any proceeding with or the obtaining of any order,
ruling or consent from any governmental or regulatory authority under any
Canadian or United States federal, provincial or state law or regulation or
pursuant to the rules and regulations of any regulatory authority, or the
fulfillment of any other legal requirement (collectively, the "Applicable Laws")
before such shares (or such other shares or securities) may be issued by Parent
and delivered by Parent at the direction of Subco or the Company, if applicable,
to the holder of surrendered Exchangeable Shares or in order that such shares
(or such other shares or securities) may be freely traded thereafter (other than
contractual restrictions or any restrictions on transfer by reason of a holder
being a "control person" of Parent for purposes of Canadian federal or
provincial securities law or an "affiliate" of Parent or the Company for
purposes of United States federal or state securities law), Parent will in good
faith expeditiously take all such actions and do all such things as are
necessary to cause such shares of Parent Common Stock (or such other shares or
securities) to be and remain duly registered, qualified or approved. Parent will
in good faith take all actions and do all things as are reasonably necessary or
desirable under Applicable Laws as they exist on the date hereof to cause the
shares of Parent Common Stock (and such other shares or securities) to be issued
and delivered hereunder to be freely tradeable thereafter (other than
contractual restrictions or any restrictions on transfer by reason of a holder
being a "control person" of Parent for the purposes of Canadian federal and
provincial securities law or an "affiliate" of Parent or the Company for
purposes of United States federal or state securities law). Parent will in good
faith expeditiously take all such actions and do all such things as are
reasonably necessary to cause all shares of Parent Common Stock (or such other
shares or securities) to be delivered hereunder to be listed, quoted or posted
for trading on all stock exchanges and quotation systems on which outstanding
shares of Parent Common Stock (or such other shares or securities) are listed,
quoted or posted for trading at such time.
 
    2.7  ECONOMIC EQUIVALENCE.
 
    (a) Parent will not, without the prior approval of the Company and the prior

<PAGE>
    (b) Parent will not, without the prior approval of the Company and the prior
approval of the holders of the Exchangeable Shares given in accordance with
Article 10 of the Exchangeable Share Provisions:
 
    (i) subdivide, redivide or change the then outstanding shares of Parent
        Common Stock into a greater number of shares of Parent Common Stock; or
 
    (ii) reduce, combine or consolidate or change the then outstanding shares of
         Parent Common Stock into a lesser number of shares of Parent Common
         Stock, or
 
   (iii) reclassify or otherwise change the shares of Parent Common Stock or
         effect an amalgamation, merger, reorganization or other transaction
         affecting the shares of Parent Common Stock;
 
unless the Company is permitted under applicable law to make the same or an
economically equivalent change to, or in the rights of holders of, the
Exchangeable Shares and the same or an economically equivalent change is
simultaneously made to, or in the rights of, the holders of the Exchangeable
Shares.
 
    (c) Parent will ensure that the record date for any event referred to in
subsection 2.7 (a) or 2.7 (b) above, or (if no record date is applicable for
such event) the effective date for any such event, is not less than 20 Business
Days after the date on which such event is declared or announced by Parent (with
simultaneous notice thereof to be given by Parent to Subco and the Company).
 
    (d) Subco and the Company agree that, to the extent required, upon due
notice from Parent, Subco and the Company will use their best efforts to take or
cause to be taken such steps as may be necessary for the purposes of ensuring
that appropriate dividends are paid or other distributions are made by the
Company, or subdivisions, redivisions or changes are made to the Exchangeable
Shares, in order to implement the required economic equivalence with respect to
the Parent Common Stock and Exchangeable Shares as provided for in this Section
2.7.
 
    (e) The Board of Directors of the Company shall determine, in good faith and
in its sole discretion, economic equivalence for the purposes of any event
referred to in section 2.7(a) or 2.7(b) above and each such determination shall
be conclusive and binding on Parent. In making each such determination, the
following factors shall, without excluding other factors determined by the Board
of Directors of the Company to be relevant, be considered by the Board of
Directors of the Company:
 
    (i) in the case of any stock dividend or other distribution payable in
        Parent Common Stock, the number of such shares issued in proportion to
        the number of shares of Parent Common Stock previously outstanding;
 
    (ii) in the case of the issuance or distribution of any rights, options or
         warrants to subscribe for or purchase Parent Common Stock (or
         securities exchangeable for or convertible into or carrying rights to
         acquire Parent Common Stock), the relationship between the exercise
         price of each such right, option or warrant and the current market
         value (as determined by the Board of Directors of the Company in the
         manner contemplated below) of a share of Parent Common Stock;
 
   (iii) in the case of the issuance or distribution of any other form of
         property (including without limitation any shares or securities of
         Parent of any class other than Parent Common Stock, any rights, options
         or warrants other than those referred to in subsection 2.7 (e)(ii)
         above, any evidences of indebtedness of Parent or any assets of
         Parent), the relationship between the fair market value (as determined
         by the Board of Directors of the Company in the manner contemplated
         below) of such property to be issued or distributed with respect to
         each outstanding share of Parent Common Stock and the current market
         value (as determined by the Board of Directors of the Company in the
         manner contemplated below) of a share of Parent Common Stock;
 
    (iv) in the case of any subdivision, redivision or change of the then
         outstanding shares of Parent Common Stock into a greater number of
         shares of Parent Common Stock or the reduction, combination,
         consolidation or change of the then outstanding shares of Parent Common
         Stock into a lesser number of shares of Parent Common Stock or any
         amalgamation, merger, reorganization or other transaction affecting
         Parent Common Stock, the effect thereof upon the then outstanding
         shares of Parent Common Stock; and
 
                                      
<PAGE>
    (v) in all such cases, the general taxation consequences of the relevant
        event to holders of Exchangeable Shares to the extent that such
        consequences may differ from the taxation consequences to holders of
        Parent Common Stock as a result of differences between taxation laws of
        Canada and the United States (except for any differing consequences
        arising as a result of differing marginal taxation rates and without
        regard to the individual circumstances of holders of Exchangeable
        Shares).
 
For purposes of the foregoing determinations, the current market value of any
security listed and traded or quoted on a securities exchange shall be the
weighted average of the daily trading prices of such security during a period of
not less than 20 consecutive trading days ending not more than three trading
days before the date of determination on the principal securities exchange on
which such securities are listed and traded or quoted; provided, however, that
if in the opinion of the Board of Directors of the Company the public
distribution or trading activity of such securities during such period does not
create a market which reflects the fair market value of such securities, then
the current market value thereof shall be determined by the Board of Directors
of the Company, in good faith and in its sole discretion, and provided further
that any such determination by the Board of Directors of the Company shall be
conclusive and binding on Parent.
 
    2.8  TENDER OFFERS, ETC.  In the event that a tender offer, share exchange
offer, issuer bid, take-over bid or similar transaction with respect to Parent
Common Stock (an "Offer") is proposed by Parent or is proposed to Parent or its
shareholders and is recommended by the board of directors of Parent, or is
otherwise effected or to be effected with the consent or approval of the board
of directors of Parent, and the Exchangeable Shares are not redeemed by the
Company or purchased by Subco pursuant to the Redemption Call Right, Parent will
use its reasonable efforts expeditiously and in good faith to take all such
actions and do all such things as are necessary or desirable to enable and
permit holders of Exchangeable Shares to participate in such Offer to the same
extent and on an equivalent basis as the holders of shares of Parent Common
Stock, without discrimination. Without limiting the generality of the foregoing,
Parent will use its reasonable efforts expeditiously and in good faith to ensure
that holders of Exchangeable Shares may participate in all such Offers without
being required to retract Exchangeable Shares as against the Company (or, if so
required, to ensure that any such retraction shall be effective only upon, and
shall be conditional upon, the closing of the Offer and only to the extent
necessary to tender or deposit to the Offer). Nothing herein shall affect or
limit the rights of the Company to redeem or Subco to purchase pursuant to the
Redemption Call Right, Exchangeable Shares, as applicable, in the event of an
Offer or an Automatic Redemption Date.
 
    2.9  OWNERSHIP OF OUTSTANDING SHARES OF SUBCO AND THE COMPANY.  Without the
prior approval of the Company and the prior approval of the holders of the
Exchangeable Shares given in accordance with Article 10 of the Exchangeable
Share Provisions, Parent covenants and agrees in favor of the Company that, as
long as any outstanding Exchangeable Shares are owned by any person or entity
other than Parent or any of its Subsidiaries, Parent will be and remain the
direct or indirect beneficial owner of all issued and outstanding voting shares
in the capital of Subco and the Company. Notwithstanding the foregoing, nothing
contained herein shall affect or limit the rights of the Company to redeem or
Subco to purchase pursuant to the Redemption Call Right, Exchangeable Shares, as
applicable, in the event of an Automatic Redemption Date.
 
    2.10  PARENT AND SUBSIDIARIES NOT TO VOTE EXCHANGEABLE SHARES.  Parent
covenants and agrees that it will appoint and cause to be appointed proxy
holders with respect to all Exchangeable Shares held by Parent and its
Subsidiaries for the sole purpose of attending each meeting of holders of
Exchangeable Shares in order to be counted as part of the quorum for each such
meeting. Parent further covenants and agrees that it will not, and will cause
its Subsidiaries not to, exercise any voting rights which may be exercisable by
holders of Exchangeable Shares from time to time pursuant to the Exchangeable
Share Provisions or pursuant to the provisions of the CBCA (or any successor or
other corporate statute by which the Company may in the future be governed) with
respect to any Exchangeable Shares held by it or by its Subsidiaries in respect
of any matter considered at any meeting of holders of Exchangeable Shares.
 
    2.11  STOCK EXCHANGE LISTING.  Parent covenants and agrees in favor of the
Company that, as long as any outstanding Exchangeable Shares are owned by any
person or entity other than Parent or any of its Subsidiaries, Parent will use
its reasonable efforts to maintain a listing for such Exchangeable Shares on a
Canadian stock exchange which is listed in section 3200 of the Regulations made
under the Income Tax Act (Canada).
 
                                      
<PAGE>
    2.12  RULE L0B-18 PURCHASES.  Nothing contained in this Agreement, including
without limitation the obligations of Parent contained in Section 2.8 hereof,
shall limit the ability of Parent or any Subsidiary to make a "Rule l0b-18
Purchase" of Parent Common Stock pursuant to Rule l0b-18 of the U.S. Securities
Exchange Act of 1934, as amended, or any successor provisions thereof.
 
                                  ARTICLE III
                               PARENT SUCCESSORS
 
    3.1  CERTAIN REQUIREMENTS IN RESPECT OF COMBINATION, ETC.  Parent shall not
enter into any transaction (whether by way of reconstruction, reorganization,
consolidation, merger, transfer, sale, lease or otherwise) whereby all or
substantially all of its undertaking, property and assets would become the
property of any other Person or, in the case of a merger, of the continuing
corporation resulting therefrom, but may do so if:
 
    (a) such other Person or continuing corporation (the "Parent Successor"), by
       operation of law, becomes, without more, bound by the terms and
       provisions of this Agreement or, if not so bound, executes, prior to or
       contemporaneously with the consummation of such transaction an agreement
       supplemental hereto and such other instruments (if any) as are reasonably
       necessary or advisable to evidence the assumption by the Parent Successor
       of liability for all moneys payable and property deliverable hereunder
       and the covenant of such Parent Successor to pay and deliver or cause to
       be delivered the same and its agreement to observe and perform all the
       covenants and obligations of Parent under this Agreement; and
 
    (b) such transaction be upon such terms as substantially preserve and do not
       impair in any material respect any of the rights, duties, powers and
       authorities of the other parties hereunder.
 
    3.2  VESTING OF POWERS IN PARENT SUCCESSOR.  Whenever the conditions of
Section 3.1 hereof have been duly observed and performed, the parties, if
required by Section 3.1 hereof, shall execute and deliver the supplemental
agreement hereto and thereupon the Parent Successor shall possess and from time
to time may exercise each and every right and power of Parent under this
Agreement in the name of Parent or otherwise and any act or proceeding by any
provision of this Agreement required to be done or performed by the board of
directors of Parent or any officers of Parent may be done and performed with
like force and effect by the directors or officers of such Parent Successor.
 
    3.3  WHOLLY-OWNED SUBSIDIARIES.  Nothing herein shall be construed as
preventing the amalgamation or merger of any wholly-owned subsidiary of Parent
with or into Parent or the winding-up, liquidation or dissolution of any
wholly-owned subsidiary of Parent provided that all of the assets of such
subsidiary are transferred to Parent or another wholly-owned subsidiary of
Parent, and any such transactions are expressly permitted by this Article 3.
 
                                   ARTICLE IV
                                    GENERAL
 
    4.1  TERM.  This Agreement shall come into force and be effective as of the
date hereof and shall terminate and be of no further force and effect at such
time as no Exchangeable Shares (or securities or rights convertible into or
exchangeable for or carrying rights to acquire Exchangeable Shares) are held by
any party other than Parent and any of its Subsidiaries.
 
    4.2  CHANGES IN CAPITAL OF PARENT AND THE COMPANY.  Notwithstanding the
provisions of Section 4.4 hereof, at all times after the occurrence of any event
effected pursuant to Section 2.7 or 2.8 hereof, as a result of which either
Parent Common Stock or the Exchangeable Shares or both are in any way changed,
this Agreement shall forthwith be amended and modified as necessary in order
that it shall apply with full force and effect, mutatis mutandis, to all new
securities into which Parent Common Stock or the Exchangeable Shares or both are
so changed, and the parties hereto shall execute and deliver an agreement in
writing giving effect to and evidencing such necessary amendments and
modifications.
 
    4.3  SEVERABILITY.  If any provision of this Agreement is held to be
invalid, illegal or unenforceable, the validity, legality or enforceability of
the remainder of this Agreement shall not in any way be affected or
 
                                      
<PAGE>
impaired thereby and this Agreement shall be carried out as nearly as possible
in accordance with its original terms and conditions.
 
    4.4  AMENDMENTS, MODIFICATIONS, ETC.  This Agreement may not be amended,
modified or waived except by an agreement in writing executed by the Company,
Subco and Parent and approved by the holders of the Exchangeable Shares in
accordance with Article 10 of the Exchangeable Share Provisions.
 
    4.5  MINISTERIAL AMENDMENTS.  Notwithstanding the provisions of section 4.4,
the parties to this Agreement may in writing, at any time and from time to time,
without the approval of the holders of the Exchangeable Shares, amend or modify
this Agreement for the purposes of:
 
    (a) adding to the covenants of any or all parties provided that the board of
       directors of each of Parent, Subco and the Company shall be of the good
       faith opinion that such additions will not be prejudicial to the rights
       or interests of the holders of the Exchangeable Shares;
 
    (b) making such amendments or modifications not inconsistent with this
       Agreement as may be necessary or desirable with respect to matters or
       questions which, in the opinion of the board of directors of each of
       Parent, Subco and the Company, it may be expedient to make, provided that
       each such board of directors shall be of the opinion that such amendments
       or modifications will not be prejudicial to the interests of the holders
       of the Exchangeable Shares; or
 
    (c) making such changes or corrections which, on the advice of counsel to
       Parent, Subco and the Company, are required for the purpose of curing or
       correcting any ambiguity or defect or inconsistent provision or clerical
       omission or mistake or manifest error, provided that the boards of
       directors of each of Parent, Subco and the Company shall be of the good
       faith opinion that such changes or corrections will not be prejudicial to
       the interests of the holders of the Exchangeable Shares.
 
    4.6  MEETING TO CONSIDER AMENDMENTS.  The Company, at the request of Parent,
shall call a meeting or meetings of the holders of the Exchangeable Shares for

Company, the Exchangeable Share Provisions and all applicable laws.
