The rights, privileges, restrictions and conditions attaching to the Class B
Shares of the Corporation are as follows:

Dividends

2.2.1 Subject to applicable law, the directors may at any time or from time to

     fiscal year shall not be declared in full. If within four months after the
     expiration of any fiscal year of the Corporation the directors in their
     discretion shall not declare the said dividend or any part thereof on the
     Class B Shares for such fiscal year, then the rights of the holders of the
     Class B Shares to such dividend or to any undeclared part thereof for such
     fiscal year shall be forever extinguished. The holders of the Class B
     Shares shall not be entitled to any dividends other than or in excess of
     the non-cumulative dividends hereinbefore provided for. Dividends shall be
     paid in cash or cheque unless the holder of the Class B Shares agrees with
     the Corporation as to some other method of form of payment.

Redemption

2.2.2.1 Right to Redeem. Subject to applicable law, the Corporation may upon
     giving notice hereinafter provided redeem the whole or any part of the then
     outstanding Class B Shares on payment for each particular share to be
     redeemed of an amount equal to the Class B Share's Aggregate Redemption
     Price.

2.2.2.2 Adjustments in the Redemption Price

     (a)  The Redemption Price of a Class B Share shall be adjusted by the
          Directors so as to ensure that the fair market value of the Class B
          Shares issued as partial or total consideration for any Assets
          purchased by the Corporation shall equal the difference between the
          fair market value of the Assets as at the Effective Date and the value
          of the non-share consideration (if any) paid by the Corporation as
          partial consideration for the Assets.

     (b)  If at any time or from time to time after the Effective Date:

          (i)  An Authority proposes to take issue or issues an Assessment and
               the fair market value of the Assets or the fair market value of
               the Class B Shares assumed therein as at the Effective Date is
               accepted as correct by the Affected Parties;

                                       -3-



          (ii) The Assessment is disputed and a final settlement is reached with
               the Authority by the Affected Parties as to the fair market value
               of the Assets or the fair market value of the Class B Shares as
               at the Effective date;

          (iii) A court of competent jurisdiction determines that the fair
               market value of the Assets or the fair market value of the Class
               B Shares as at the Effective Date, was different than the
               Original Value and no appeal from such determination has been
               filed and the relevant appeal period has expired; or

          (iv) A Vendor or the corporation informs the other in writing that the
               fair market value of the Assets or the fair market value of the
               Class B Shares as at the Effective Date was different that the
               Original Value and the Vendors and the Corporation agree that
               such different amount is correct;

          then the purchase price for the Assets or the fair market value of the
          Class B Shares (as the case may be) as at the Effective Date shall be
          deemed to be the fair market value so determined (the "Amended Value")
          and the then Redemption Price shall be increased or decreased to
          reflect the difference between the Amended Value and the Original
          Value.

     (c)  If all of the Class B Shares issued to the Vendors pursuant to the
          Sale Agreement are still issued and outstanding, the then Redemption
          Price of a Class B Share shall be increased or decreased to reflect
          the difference between the Amended Value and the Original Value.

     (d)  If some or all of the Class B Shares issued to the Vendors pursuant to
          the Sale Agreement have been redeemed by the Corporation prior to the
          date of a downward adjustment to the then Redemption Price, the
          shareholder who held such shares at the time of their redemption shall
          forthwith pay to the Corporation, for each Class B Share so redeemed,
          an amount equal to the difference between the Redemption Price at the
          time of the redemption and the Redemption Price so adjusted. Such
          shareholder and the Corporation may agree that the total amount so
          payable to the Corporation may be paid by a corresponding downward
          adjustment to the Redemption Price of any remaining Class B Shares
          held by such shareholder or in cash or by assumption or issuance of
          debt or any combination thereof.

     (e)  If some or all of the Class B Shares issued to the vendors pursuant to
          the Sale Agreement have been redeemed by the Corporation prior to the
          date of an upward adjustment to the then Redemption Price, the
          Corporation shall forthwith pay to the shareholder who held such
          shares at the time of their redemption, for each such Class B Share so
          redeemed, an amount equal to the difference between the Redemption
          Price so adjusted. Such shareholder and the Corporation may agree
          that the total amount so payable to the shareholder may be paid by a
          corresponding upward adjustment to the Redemption Price of any
          remaining Class B Shares held by such

                                       -4-



          shareholder or in cash or by assumption or issuance of debt or any
          combination thereof.

     (f)  In the event that subsequent to the issuance of a Class B Share the
          stated capital account of the Class B Shares is reduced in a manner
          authorized by law, the Redemption Price of a Class B Share, as
          determined in the manner hereinbefore provided, shall be deemed to be
          the amount so determined less the quotient obtained by dividing the
          amount of the stated capital reduction so authorized by the number of
          Class B Shares issued at the time of the stated capital account
          reduction so authorized.

     (g)  Any adjustments pursuant to this section 2.2 (other than an adjustment
          contemplated pursuant to section 2.2.2.2(f) hereof) shall be
          retroactive, __ pro tune, to the date of the issuance of Class B
          Shares.

2.2.2.3 Partial Redemption. If less than all the Class B Shares are at any time
     to be redeemed, the shares to be redeemed shall be selected in such manner
     as the directors of the Corporation may deem equitable or, if the directors
     so determine, on a pro rata basis, disregarding fractions, according to the
     number of Class B Shares held by each of the holders of Class B Shares. If
     a part only of the Class B Shares represented by any certificate are to be
     redeemed, a new certificate representing the balance of such shares shall
     be issued to the holder thereof at the expense of the Corporation upon
     presentation and surrender to the first mentioned certificate.

     For greater certainty, the redemption by the Corporation of any holder's
     Class B Shares pursuant hereto shall not entitle any other holder of Class
     B Shares to demand redemption be made with respect to their Class B Shares.

2.2.2.4 Method of Redemption. In any case of redemption of Class B Shares
     pursuant hereto, the Corporation shall, not more than forty-five(45) days
     and not less than thirty(30) days before the date specified for redemption,
     send by prepaid first class mail or deliver to each person who at a date
     not more than seven(7) days prior to the date of mailing or delivery is a
     holder of Class B Shares to be redeemed, a notice in writing of the
     intention of the Corporation to redeem the Class B Shares registered to the
     name of such holder. Accidental failure or omission to give such notice to
     one or more holders shall not affect the validity of such redemption, but
     upon such failure or omission being discovered notice shall be given
     forthwith to such holder or holders and such notice shall have the same
     force and effect as if given in due time. Such notice required to be given
     in this clause may be waived when and if the registered holders of Class B
     Shares to be redeemed signify their consent to such waiver and execute a
     formal waiver in favour of the Corporation relieving the Corporation from
     the obligation of giving notice to such registered holders. Such notice
     given pursuant to this clause shall set out the number of Class B Shares
     which are to be redeemed held by the person to whom it is addressed, the
     Redemption Price, the date specified for redemption and the office or
     offices of the Corporation and any other place or places within Canada at
     which holders of Class B Shares may present and surrender certificates
     representing such shares for redemption. On and after the date so specified
     for redemption, the Corporation shall pay or cause to be

                                       -5-



     paid to or to the order of the holders of the Class B Shares to be
     redeemed, the aggregate Redemption Price of such shares on presentation and
     surrender at the office of the Corporation designated in the aforesaid
     notice of redemption and at any other place or places within Canada
     specified in such notice of redemption, of the certificate or certificates
     representing the Class B Shares called for redemption.

2.2.2.5 Method of Payment. Payment in respect of Class B Shares being redeemed
     shall subject as hereafter provided, be made by cheque in the amount of the
     Aggregate Redemption Price payable to the holder thereof at par at any
     branch in Canada of any Canadian chartered bank in a principal amount equal
     to the Aggregate Redemption Price. Such cheque shall satisfy and discharge
     all liability of the Corporation for the Aggregate Redemption Price, to the
     extent of the amount represented thereby, unless such cheque is not paid on
     due presentation. From and after the date specified for redemption in any
     such notice of redemption, the Class B Shares called for redemption shall
     cease to be entitled to dividends or any other participation in the assets
     of the Corporation and the holders thereof shall not be entitled to
     exercise any of their other rights as shareholders in respect thereof
     unless payment of the Aggregate Redemption Price shall not be made upon
     presentation and surrender of the certificates in accordance with the
     foregoing provisions, in which case the rights of the holders shall remain
     unaffected. The Corporation shall have the right, at any time after the
     mailing or delivery of notice of its intention to redeem Class B Shares, to
     deposit the Aggregate Redemption Price of the Class B Shares so called for
     redemption, or of such of the Class B Shares which are represented by
     certificates which have not at the date of such deposit been surrendered by
     the holders thereof in connection with such redemption, to a special
     account maintained by the Corporation with a branch of a Canadian chartered
     bank designated by the Corporation in the notice of redemption (the
     "Trustee") to be paid without interest to or to the order of the respective
     holders of Class B Shares whose shares have been called for redemption,
     upon presentation and surrender to the Trustee of the certificates
     representing such shares. Upon such deposit being made or upon the date
     specified for redemption in such notice, whichever is later, the Class B
     Shares in respect of which such deposit shall have been made shall be
     deemed to have been redeemed and the rights of the holders thereof shall be
     limited to resolving their proportion of the amount so deposited without
     interest, upon presentation and surrender to the Trustee of the certificate
     or certificates representing the Class B Shares being redeemed. Any
     interest earned on any such deposit shall belong to the Corporation.
     Notwithstanding the foregoing the Aggregate Redemption Price, to the extent
     that it is represented by a cheque, which has not been presented for
     payment by the 6th anniversary of the relevant redemption date, shall be
     forfeited to the Corporation. Notwithstanding anything herein contained,
     the Corporation and the holder of Class B Shares can agree to payment of
     the Aggregate Redemption Price in a manner other than by a cheque from the
     Corporation.

Retraction.

2.2.3.1 Right in Retract. Subject to applicable law, each holder of Class B
     Shares shall be entitled to require the Corporation to redeem all or any
     of the Class B Shares registered in

                                       -6-



     the name of the holder by payment for each share to be redeemed of the
     aggregate Redemption Price thereof.

2.2.3.2 Method of Retraction. Each holder of Class B Shares who elects to have
     the Corporation redeem all or any Class B Shares registered in the name of
     that holder shall deposit at the registered office of the Corporation the
     certificate or certificates representing the Class B Shares which that
     holder desires to have redeemed by the Corporation. The holder of Class B
     Shares shall, at the time of depositing such certificates, also file with
     the Corporation a notice of election to redeem, which notice shall set out
     the Redemption Price and the retraction date (which shall be not less than
     thirty(30) days and not more than forty-five(45) days after the deposit of
     such certificate or certificates and filing of such notice of election).
     Such notice required to be given in this clause may be waived when and if
     the Corporation signifies its consent to waiver and executes a formal
     waiver in favour of the holder of Class B Shares to be retracted. The
     Corporation shall, on the retraction date, redeem the Class B shares in
     respect of which certificates have been deposited and in respect of which
     the holder of Class B Shares has signified its election as aforesaid, by
     paying the Aggregate Redemption Price to the holder of Class B Shares
     entitled thereto.

2.2.3.3 Method of Payment. Payment of the Aggregate Redemption Price made in
     accordance with the foregoing provisions shall, subject as hereafter
     provided, be made by cheque in the amount of the Aggregate Redemption Price
     payable to or to the order of the holder of Class B Shares entitled thereto
     at par at any branch in Canada of a Canadian chartered bank in a principal
     amount equal to the Aggregate Redemption Price. Such cheque shall satisfy
     and discharge all liability of the Corporation for the Aggregate Redemption
     Price, to the extent of the amount represented thereby, unless such cheque
     is not paid on due presentation. The Class B Shares in respect of which
     payment is made in accordance with the foregoing provisions shall be deemed
     to have been redeemed on the date on which such payment is made and the
     holder thereof shall cease to be entitled to dividends or to exercise any
     of the rights of holders thereof from such date, unless payment of the
     Redemption Price is not made as aforesaid in which event the rights of the
     holder of such Class B Shares shall remain ___________. Notwithstanding the
     foregoing the Aggregate Redemption Price, to the extent that it is
     represented by a cheque, which has not been presented for payment by the
     6th anniversary of the relevant retraction date, shall be forfeited to the
     Corporation. Notwithstanding anything herein contained, the Corporation and
     the holder of Class B Shares can agree to payment of the Aggregate
     Redemption Price in a manner other than by a cheque from the Corporation.

Liquidation, Dissolution or Winding Up

2.2.4 In the event of the liquidation, dissolution or winding up of the
     corporation or other distribution of the property or assets of the
     Corporation among its shareholders for the purpose of winding up its
     affairs, each holder of Class B Shares shall be entitled to receive from
     the assets and property of the Corporation, before any amount shall be paid
     or any property or assets of the Corporation distributed to the holders of
     any Class A Shares, or shares of any other class ranking junior to the
     Class B Shares, an amount equal to the Aggregate Redemption Price of the
     Class B Shares held by such holder. After

                                       -7-



     payment to the holders of the Class B Shares of the amount so payable to
     them as above provided, they shall not be entitled to share in any further
     distribution of the property or assets of the Corporation.

Voting Rights

2.2.5 The holders of the Class B Shares shall not be entitled as such (except as
     hereinafter specifically provided and except as otherwise provided by law)
     to receive notice of or to attend at any meeting of the shareholders of the
     Corporation and shall not be entitled to vote at any such meeting.

Priority

2.2.6 The foregoing provisions in relation to the Class B Shares shall not be
     repeated, modified or altered nor shall any other class of shares be
     created ranking prior or equal to the Class B Shares unless by special
     resolution of the holders of Class B Shares and any other class of shares
     of the Corporation entitled to vote thereon.

PRIORITY AS TO DIVIDENDS AND RESTRICTIONS ON DIVIDENDS AND DISTRIBUTION

2.3.1 Except as provided herein, the directors of the Corporation when declaring
     any dividends on the Class A Shares and Class B Shares may, in their sole
     discretion, elect to declare dividends on one class of shares to the
     exclusion of the other classes of shares.

2.3.2 Notwithstanding anything herein contained, no dividends or distribution of
     any kind whatsoever shall be declared or made in respect of any class of
     shares of the Corporation which will have the affect of reducing the net
     realizable value (including goodwill) of the Corporation to an amount
     insufficient to enable the redemption by the Corporation of all of the
     Class B Shares issued and outstanding.
