            Parties for thirty (30) Business Days (the "OFFER PERIOD") from the
            receipt of the Offer by the Notified Parties.

      The Notified Parties shall be obliged by delivering notice to the Offering
      Party within, but not after the expiration of, the Offer Period at their
      sole option to either accept the Offer or reject the Offer. If a Notified
      Party does not accept the Offer, then such Notified Party shall be deemed
      to have rejected the Offer. If a Notified Party has accepted the Offer,
      then the Offering Party shall sell to the Notified Party, and the Notified
      Party shall purchase from the Offering Party, the Offered Securities in
      accordance with this Agreement. If both Notified Parties accept the Offer,
      the Offered Securities shall be sold to the Corporation.

(b)   If both of the Notified Parties have or are deemed to have rejected the
      Offer, then the Offering Party shall be free for a period of thirty (30)
      Business Days from the end of the Offer Period to sell all, but not less
      than all, of the Offered Securities

      (i)   in the case of a Third Party Offer, to the Third Party on terms not
            more favourable in the aggregate for the Third Party than those
            contained in the Third Party Offer; or

      (ii)  in the case of a Management Investor Offer, to any Person on terms
            not more favourable, in the aggregate, for such Person than those
            contained in the Offer;

      provided, however, that in either case it shall be a condition precedent
      to the right of the Offering Party to sell the Offered Securities that the
      purchaser has

<PAGE>

                                      -9-

            executed a counterpart of this Agreement in accordance with Section
            6.5. If no sale takes place within the said thirty (30) Business Day
            period, then the Offering Party shall not transfer the Offered
            Securities without again following and being subject to this Article
            III.

3.4 RIGHT OF FIRST REFUSAL - MANAGEMENT INVESTORS

      (a)   If one or more Shareholders holding, in the aggregate, not less than
            seventy-five percent (75%) of the Shares (collectively, the
            "MAJORITY OFFERING PARTY") should receive a bona fide irrevocable
            written offer (the "THIRD PARTY OFFER") from a Person dealing at
            arms' length (within the meaning of the Income Tax Act (Canada))
            with the Majority Offering Party (the "THIRD PARTY"), to purchase
            all (but not less than all) of the Shares held by the Majority
            Offering Party, which it has accepted or intends to accept, then the
            Majority Offering Party shall first offer to sell (the "OFFER") such
            Shares (the "OFFERED SECURITIES") to the Management Investors in
            accordance with the procedure set forth in this Section 3.4. The
            Offer shall be sent to each Management Investor, shall include a
            copy of the Third Party Offer, and shall contain terms and
            conditions not less favourable, in the aggregate, for the Management
            Investors than those contained in the Third Party Offer. The Offer
            shall open for acceptance by the Management Investors for thirty
            (30) Business Days (the "OFFER PERIOD") from the receipt of the
            Offer by the Management Investors.

      (b)   The Management Investors shall be obliged by notice delivered by the
            Nominee to the Majority Offering Party within, but not after the
            expiration of, the Offer Period at their sole option to either
            accept the Offer or reject the Offer. If a Management Investor does
            not accept the Offer, then such Management Investor shall be deemed
            to have rejected the Offer. If all of the Management Investors have
            accepted the Offer, then the Majority Offering Party shall sell to
            each Management Investor, and each Management Investor shall
            purchase from the Majority Offering Party, within thirty (30)
            Business Days following the end of the Offer Period, such Management
            Investor's pro rata share of the Offered Securities in accordance
            with this Agreement.

      (c)   If one or more (but not all) of the Management Investors reject or
            are deemed to have rejected the Offer, then every Management
            Investor having accepted the Offer shall have the right to purchase
            his or her pro rata share of the unaccepted Offered Securities (the
            "ADDITIONAL OFFER"); and the Additional Offer shall be repeated
            until (i) all of the Offered Securities are accepted or (ii) the
            Offer Period expires without all of the Offered Securities having
            been accepted. If, following one or more Additional Offers, all of
            the unaccepted Offered Securities are accepted, then the Majority
            Offering Party shall sell to each Management Investor having
            accepted the Offer or the Additional Offer, and each such Management
            Investor shall purchase from the Majority Offering Party, within
            thirty (30) Business Days following the end of the Offer Period,
            such Management Investor's pro rata share of the Offered Securities
            and the unaccepted Offered Securities in accordance with this
            Agreement. If less than all

<PAGE>

                                      -10-

            of the Offered Securities are accepted following one or more
            Additional Offers, then all of the Management Investors shall be
            deemed to have rejected the Offer and the Additional Offer.

      (d)   If the Management Investors have or are deemed to have rejected the
            Offer and the Additional Offer, then the Majority Offering Party
            shall be free for a period of thirty (30) Business Days from the end
            of the Offer Period to sell all, but not less than all, of the
            Offered Securities to the Third Party on terms not more favourable
            in the aggregate for the Third Party than those contained in the
            Third Party Offer; provided, however, that it shall be a condition
            precedent to the right of the Majority Offering Party to sell the
            Offered Securities that the purchaser has executed a counterpart of
            this Agreement in accordance with Section 6.5. If no sale takes
            place within the said thirty (30) Business Day period, then the
            Majority Offering Party shall not transfer the Offered Securities
            without again following and being subject to this Article III.

3.5 DRAG ALONG RIGHTS; PIGGY-BACK RIGHTS

      If the Management Investors have or are deemed to have rejected the Offer
and the Additional Offer pursuant to Section 3.4(d), such that the Majority
Offering Party has the right to sell all but not less than all of the Offered
Securities to the Third Party, then:

      (a)   the Majority Offering Party shall also have the right, upon written
            notice to the other Shareholders, to require that the other
            Shareholders sell all of the Shares held by such Shareholders
            together with the Shares held by the Majority Offering Party on the
            same terms as those contained in the Third Party Offer. In such
            event, such Shareholders shall be obliged to sell all of the Shares
            held by them in accordance with the terms of the Third Party Offer;
            and

      (b)   each Management Investor shall have the right, at such Management
            Investor's option, to require that all of the Shares held by such
            Management Investor be included in the sale contemplated by the
            Third Party Offer. If a Management Investor wishes to exercise the
            right granted in this Section 3.5(b), then it shall do so by notice
            sent by the Nominee to the Majority Offering Party within, but not
            after, five (5) Business Days of the end of the Offer Period.

3.6 NOMINEE

      (a)   For the purposes of Section 3.4 and Section 3.5(b), each Management
            Investor hereby appoints Thomas A. Andruskevich (or any other
            individual designated by the Management Investors in accordance with
            Section 3.6(b) below) as its nominee (the "NOMINEE") to represent
            such Management Investor in the exercise of its rights under Section
            3.4 and Section 3.5(b), including, without limitation, to represent
            and act on behalf of each Management Investor, in accordance with
            the instructions of each such Management Investor, in all
            correspondence and other communications to and from Holdings in
            accordance with Section 6.2 hereof.

<PAGE>

                                      -11-

      (b)   The Nominee may be replaced (i) at any time by the Management
            Investors, by the vote of the holders of a majority of the Shares
            held in the aggregate by Management Investors as at such date; or
            (ii) by Holdings, in the event that the Nominee resigns, is
            incapable of acting or refuses to act, if the Nominee is not
            replaced in accordance with the provisions hereof within five (5)
            Business Days of written notice from Holdings of such resignation,
            incapacity or refusal to act. All Parties shall be notified of any
            such change of Nominee in accordance with the notice provisions set
            out in Section 6.2 hereof.

3.7 TRIGGER EVENT

      Upon the occurrence of a Trigger Event in connection with a Management
Investor, such Management Investor or his heirs, executors or other legal
representatives, as the case may be, (the "TRIGGER EVENT OFFERING PARTY") shall
be deemed to have offered for sale to Holdings all, but not less than all, of
the Shares held by the Trigger Event Offering Party immediately prior to the
Trigger Event (the "OFFERED SECURITIES") for an amount per share equal to the
Value of the Offered Securities, and Holdings shall have the option to purchase
such Offered Securities.

      This option may be exercised by Holdings giving notice thereof to the
Trigger Event Offering Party within fifteen (15) Business Days from the Trigger
Date. The Trigger Event Offering Party shall forthwith give notice to Holdings
of any Trigger Event.

      If Holdings does not exercise the option in this Section 3.7, then, to the
extent permitted by law, the Corporation shall purchase from the Trigger Event
Offering Party, and the Trigger Event Offering Party shall sell to the
Corporation, the Offered Securities for an amount per share equal to the Value
of the Offered Security.

3.8 PRECEDENCE OF OFFERS AND RIGHTS

      In the event that any Offer or Third Party Offer or Trigger Event shall
take place pursuant to Sections 3.3, 3.4, 3.5 or 3.7, respectively at a time
when any other such Offer or Third Party Offer or Trigger Event may have been
made with respect to Shares, or occurred, and prior to the conclusion of the
transactions contemplated by such Offer, Third Party Offer or Trigger Event,

            provisions of Sections 3.3, 3.4 and 3.7; and

      REGISTERED OFFICE OF THE CORPORATION."

3.13 DETERMINATION OF VALUE

      The auditors of the Corporation (the "AUDITORS") shall determine the Value
of a Share at least once in every fiscal year of the Corporation and, in any
event, they shall determine the value as at the last day of each fiscal year of
the Corporation. In the event that, at the time a Value must be attributed to
Shares for purposes of any of the provisions of this Article III or Section 4.1,
the Value has not been determined by the Auditors as at the last day of the most
recently completed fiscal year of the Corporation, then the Closing of the
relevant transaction

<PAGE>

                                      -13-

shall be deferred until such Value has been determined, and it is such Value
which shall be applied to such transaction.

      Notwithstanding the foregoing, in the event that, at the time that a Value
must be attributed to Shares for purposes of any of the provisions of this
Article III or Section 4.1, more than three (3) months have passed since the
date as of which the Value of the Shares was last determined by the Auditors,
any Management Investor who is selling Shares pursuant to this Article III shall
be entitled to require a new valuation of the Shares, in which case the Auditors
shall determine the Value of the Shares as at the last day of the most
recently-completed monthend of the Corporation, and all costs, fees and expenses
of such valuation shall be borne equally by such Management Investor and the
Corporation.

                                   CONVERSION

4.1 CONVERSION PRIVILEGE

      In the event that the Corporation does not issue and does not intend to
issue shares of its share capital to the general public and that Holdings

and option (exercised by written notice to Holdings) to cause Holdings to
exchange the Shares held by such Management Investors for securities in the
share capital of Holdings which securities shall have a value (without reference
to their proposed issue price) identical to the Value of the Shares held by the
Management Investors. In the event of any dispute between Holdings and the
Management Investors as to the number or value of the securities in the share
capital of Holdings to be issued in accordance herewith (or anything incidental
thereto), same shall be absolutely determined by a recognized business valuator
having offices in Montreal, to be designated by Holdings with the approval of
Management Investors holding at least twenty-five percent (25%) of the total

or trial.

conversion of the Shares, Holdings shall satisfy all of its obligations under
