                     pursuant to paragraphs 2.2(f)(i) through 2.2(f)(ix)
                     herein, an amount equal to the quotient obtained when the
                     stated capital maintained for the Class "I" shares is
                     divided by the number of Class "I" shares then
                     outstanding; and

            (xi)     thereafter, the holders of Class "A", "B", "C", "D", "E",
                     "F", "G", "H" and "I" shares shall be entitled to
                     participate equally amongst themselves in respect of each
                     share held in any further distribution of the assets of
                     the Corporation.

            An unlimited number of Class "J" Voting Redeemable Preferred Shares
(in this paragraph referred to as the "Class "J" Voting Redeemable Preferred

exchange for property, (other than a promissory note or a promise to pay), and
the Class "J" Voting Redeemable Preferred Shares shall have the following
rights, restrictions, privileges, conditions and limitations:
   9
                                      -4-


(a)  Dividend Rights

     The holders of Class "J" Voting Redeemable Preferred Shares shall be
     entitled to receive dividends as and when declared by the Directors but
     always in preference and priority to any payment of dividends on any other
     shares of the Corporation (except any shares which by their terms are
     specifically stated to rank prior to the Class "J" Voting Redeemable
     Preferred Shares in the declaration and payment of dividends) out of the
     monies of the Corporation properly applicable to the payment of dividends,
     which dividends shall be non-cumulative preferential dividends at a rate
     per annum equal to the prescribed rate of interest for the purposes of
     subsection 256(11) of the Income Tax Act (Canada) as of the time of
     issuance of the first then issued shares of the particular class (the
     "Prescribed Rate") in each case on the Redemption Amount thereof (as
     described herein) as may be determined by the Directors, payable at such
     time or times and at such place or places as the Directors may determine.
     The Directors shall be entitled from time to time to declare part of the
     said non-cumulative dividend for any fiscal year notwithstanding that such
     dividend for such fiscal year shall not be declared in full. The said
     dividends shall be non-cumulative whether earned or not earned and if in
     any fiscal year the Directors in their discretion shall not declare the
     said dividends or any part thereof, then the right of the holders of the
     Preferred shares to such dividends or to any undeclared part thereof for
     the fiscal year shall be extinguished. The holders of the Class "J" Voting
     Redeemable Preferred Shares shall in no circumstances be entitled to any
     dividends other than or in excess of the non-cumulative dividends at the
     rate herein provided for.

(b)  Repayment of Capital

     In the event of the liquidation, dissolution or winding up of the
     Corporation or other distribution of its assets amongst the shareholders by
     way of repayment of capital, the holders of the Class "J" Voting Redeemable
     Preferred Shares shall be entitled to receive an amount per share equal to
     the Redemption Amount (as hereinafter defined) together with all declared
     but unpaid dividends thereon to the date of the liquidation, dissolution or
     winding up in priority to any distribution to the holders of any other
     shares of the Corporation (except any shares which by the terms are
     specifically stated to rank prior to the Class "J" Voting Redeemable
     Preferred Shares in respect of such distributions) and the holders of the
     Class "J" Voting Redeemable Preferred Shares shall have no further right to
     participate in profits or assets in respect of such liquidation,
     dissolution or winding up of the Corporation.

(c)  Redemption

     (i)  The Class "J" Voting Redeemable Preferred Shares, or any number
     thereof, shall be subject to redemption at an amount per share equal to the
     amount obtained by dividing the difference between the fair market value of
     the property (the "Property") transferred to the Corporation on the
     issuance of the Class "J" Voting Redeemable Preferred Shares and the amount
     of any consideration (other than Class "J" Voting Redeemable Preferred
     Shares) transferred to the transferor of the Property in connection with
     the transfer, by the number of Class "J" Voting Redeemable Preferred Shares
     issued on the transfer of the Property to the Corporation (the "Redemption
     Amount") together with all declared but unpaid dividends thereon, if any,
     at any time at the option of the Directors without the consent of the
     holders thereof. If
   10
                                     - 5 -


                    less than all of the outstanding Class "J" Voting Redeemable
                    Preferred Shares shall be so redeemed, the shares to be
                    redeemed shall at any particular time, or from time to time,
                    be selected by lot or otherwise in such manner as the
                    Directors may determine. Written notice shall be provided to
                    all holders of the number of shares redeemed and the notice
                    shall provide that payment for the redeemed shares shall be
                    made at the place in Canada designated in the aforesaid
                    notice upon surrender of the certificate or certificates for
                    the shares so redeemed. From and after the date of the
                    giving of the notice of redemption the Class "J" Voting
                    Redeemable Preferred Shares called for redemption shall be
                    deemed to be redeemed and the holders thereof shall have no
                    rights whatsoever in respect thereof except to receive the
                    payment therefor upon surrender of the certificate on
                    certificates representing the redeemed Class "J" Voting
                    Redeemable Preferred Shares. The Directors may make and
                    enforce all and any other such reasonable regulations not
                    inconsistent with this paragraph or the Articles or By-laws
                    governing the manner of the redemption of the Class "J"
                    Voting Redeemable Preferred Shares as they may in their sole
                    discretion deem advisable.

          (iii)     The Class "J" Voting Redeemable Preferred Shares or any
                    number thereof shall be subject to redemption at an amount
                    per share equal to the Redemption Amount together with all
                    declared but unpaid dividends thereon, if any, at any time
                    at the option of the holders thereof without the consent of
                    the Directors, or the Corporation, provided that if the
                    Corporation would be prevented by the Business Corporations
                    Act of Alberta or any other law in force in the Province of
                    Alberta from redeeming all of the Class "J" Voting 
                    Redeemable Preferred Shares required to be redeemed, then
                    the Corporation shall redeem, disregarding fractions, that
                    number of Class "J" Voting Redeemable Preferred Shares that
                    it is permitted by law to redeem and the Corporation shall
                    redeem the balance of the outstanding Class "J" Voting
                    Redeemable Preferred Shares in respect of which redemption
                    has been demanded by the holder at such time or times as
                    the redemption is permitted by applicable law. Payment for
                    such Class "J" Voting Redeemable Preferred Shares shall be
                    made by cheque payable at any branch in Canada of the
                    Corporation's bankers upon surrender of the certificates
                    representing the Class "J" Voting Redeemable Preferred
                    Shares to be redeemed.

          (ii)      As set out above, the Redemption Amount per share of the
                    Class "J" Voting Redeemable Preferred Shares is intended to
                    equal the difference between the fair market value of the
                    Property transferred to the Corporation on the issuance of
                    the Class "J" Voting Redeemable Preferred Shares and the
                    amount of any consideration (other than Class "J" Voting
                    Redeemable Preferred Shares) transferred to the transferor
                    of the Property in connection with the transfer divided by
                    the number of Class "J" Voting Redeemable Preferred Shares
                    issued on the transfer of the Property to the Corporation.
                    Provided that should it be determined at any time by:

                    (A)       a tribunal or court of competent jurisdiction; or
                    (B)       agreement with the Department of National
                              Revenue, Taxation; or
                    (C)       agreement between the Corporation and the holder
                              of the Class "J" Voting Redeemable Preferred
                              Shares; 
   11
                                      -6-

                  that the difference between the fair market value of the
                  Property transferred to the Corporation on the issuance of the
                  Class "J" Voting Redeemable Preferred Shares and the amount of
                  any consideration (other than Class "J" Voting Redeemable
                  Preferred Shares) transferred to the transferor of the
                  property in connection with the transfer is different from the
                  determination of such difference as made by the Directors on
                  the issuance of the Class "J" Voting Redeemable Preferred
                  Shares then, in such event, subject to the Business
                  Corporations Act of Alberta, the Redemption Amount as defined
                  herein of the Class "J" Voting Redeemable Preferred Shares
                  then issued and outstanding shall be adjusted accordingly and
                  retroactively, effective as of the date of issuance of the
                  Class "J" Voting Redeemable Preferred Shares to equal the
                  amount which is obtained by dividing the difference (as
                  determined pursuant to (A), (B) or (C) above, as the case may
                  be) between the fair market value of the Property transferred
                  to the Corporation and the amount of any consideration (other
                  than Class "J" Voting Redeemable Preferred Shares) transferred
                  to the transferor by the number of Class "J" Voting Redeemable
                  Preferred Shares issued upon the transfer of the Property to
                  the Corporation.

         (iv)     In the event that dividends are paid on the Class "J" Voting
                  Redeemable Preferred Shares between the date of issuance of
                  the Class "J" Voting Redeemable Preferred Shares and the
                  actual date of adjustment provided for above then, forthwith
                  upon any adjustment being made, an amount shall be paid by the
                  Corporation or by the recipient of the dividend on the Class
                  "J" Voting Redeemable Preferred Shares, as the case may be,
                  together with interest thereon at the prime rate of interest
                  charged by the bankers of the Corporation at the date of
                  payment of the dividends computed from the date of the payment
                  of the dividends to the date of the payment provided for in
                  this subparagraph which amount shall be equal to the
                  difference between the amount of dividend actually received
                  and the amount of dividend which would have been received if
                  the aforesaid adjustment had actually been made at the date of
                  issuance of the Class "J" Voting Redeemable Preferred Shares.

         (v)      In the event that any Class "J" Voting Redeemable Preferred
                  Shares are redeemed before the actual date of any adjustment
                  provided for above then, forthwith upon any adjustment being
                  made, an amount shall be paid by the Corporation or the
                  person whose Class "J" Voting Redeemable Preferred Shares were
                  redeemed, as the case may be, together with interest thereon
                  at the prime rate of interest charged by the bankers of the
                  Corporation at the date of the redemption of the Class "J"
                  Voting Redeemable Preferred Shares computed from the actual
                  date of payment of the Redemption Amount to the date of the
                  payment provided for in this subparagraph, which amount shall
                  be equal to the difference between the amount actually paid on
                  the redemption of the Class "J" Voting Redeemable Preferred
                  Shares and the amount which would have been paid if the
                  aforesaid adjustment had actually been made at the date of
                  issuance of then redeemed Class "J" Voting Redeemable
                  Preferred Shares.

         (vi)     The Directors shall not allot and issue any Class "J" Voting
                  Redeemable Preferred Shares or approve of the transfer of any
                  Class "J" Voting Redeemable Preferred Shares unless the person
                  to whom the shares are issued or the transferee, as the case
                  may be, is made aware of the provisions
   12
 
                                      -7-

                        of this paragraph and agrees, in a form and manner
                        satisfactory to the Directors, to be bound by and
                        comply with the provisions of this paragraph.

                (vii)   Upon any adjustment being made pursuant to the
                        provisions of this paragraph the stated capital of the
                        Class "J" Voting Redeemable Preferred Shares shall, if
                        the Directors decide that any adjustment to the stated
                        capital of the Class "J" Voting Redeemable Preferred
                        Shares is necessary or desirable, be adjusted
                        accordingly and retroactively as of the date of
                        issuance of the Class "J" Voting Redeemable Preferred
                        Shares to the amount determined by the Directors
                        subject to the provisions of the Business Corporations
                        Act of Alberta.

        (d)     Purchase for Cancellation

                The Corporation shall have the right at its option at any time
                and from time to time, to purchase for cancellation the whole
                or any part of the Class "J" Voting Redeemable Preferred Shares
                outstanding pursuant to an agreement between the Corporation
                and any holder of Class "J" Voting Redeemable Preferred Shares
                or pursuant to tenders received by the Corporation upon request
                for tenders addressed to all holders of Class "J" Voting
                Redeemable Preferred Shares at the lowest price per share at
                which in the opinion of the Directors such shares are
                obtainable but not exceeding the Redemption Amount of Class "J"
                Voting Redeemable Preferred Shares and from and after the date
                of such purchase of any Class "J" Voting Redeemable Preferred
                Shares such shares shall be regarded as having been redeemed;
                provided that, if in response to an invitation for tenders, two
                or more shareholders submit tenders at the same price and if
                such tenders are acceptable to the Corporation in whole or in
                part, then, unless the Corporation accepts all such tenders in
                whole, the Corporation shall accept such tenders in proportion
                as nearly as may be to the number of shares offered in each
                such tender.

2.2(C)          CLASS "K" NON-VOTING REDEEMABLE PREFERRED SHARES

                An unlimited number of Class "K" Redeemable Preferred Shares (in
this paragraph referred to as the "Class "K" Redeemable Preferred Shares") have
been created by the Corporation for the purpose of issuances in exchange for
property, (other than a promissory note or a promise to pay), and the Class
"K" Preferred Shares shall have the following rights, restrictions, privileges,
conditions and limitations:

        (a)     Dividend Rights

                The holders of Class "K" Preferred Shares shall be entitled to
                receive dividends as and when declared by the Directors but
                always in preference and priority to any payment of dividends
                on any other shares of the Corporation (except any shares which
                by their terms are specifically stated to rank prior to the
                Class "K" Preferred Shares in the declaration and payment of
                dividends) out of the monies of the Corporation properly
                applicable to the payment of dividends, which dividends shall
                be non-cumulative preferential dividends at a rate per annum
                equal to the prescribed rate of interest for the purposes of
                subsection 256(11) of the Income Tax Act (Canada) as of the
                time of issuance of the first then issued shares of the
                particular class (the "Prescribed Rate") in each case on the
                Redemption Amount thereof (as described herein) as may be
                determined by the Directors, payable at such time or times and
                at such place or places as the Directors may determine. The
                Directors 


   13

                                      -8-

                shall be entitled from time to time to declare part of the said
                non-cumulative dividend for any fiscal year notwithstanding
                that such dividend for such fiscal year shall not be declared
                in full. The said dividends shall be non-cumulative whether
                earned or not earned and if in any fiscal year the Directors in
                their discretion shall not declare the said dividends or any
                part thereof, then the right of the holders of the Preferred
                shares to such dividends or to any undeclared part thereof for
                the fiscal year shall be extinguished. The holders of the Class
                "K" Preferred shares shall in no circumstances be entitled to
                any dividends other than or in excess of the non-cumulative
                dividends at the rate herein provided for.

        (b)     Repayment of Capital

                In the event of the liquidation, dissolution or winding up of
                the Corporation or other distribution of its assets amongst the
                shareholders by way of repayment of capital, the holders of the
                Class "K" Preferred Shares shall be entitled to receive an
                amount per share equal to the Redemption Amount (as hereinafter
                defined) together with all declared but unpaid dividends
                thereon to the date of the liquidation, dissolution or winding
                up in priority to any distribution to the holders of any other
                shares of the Corporation (except any shares which by their
                terms are specifically stated to rank prior to the Class "K"
                Preferred Shares in respect of such distributions) and the
                holders of the Class "K" Preferred Shares shall have no further
                right to participate in profits or assets in respect of such
                liquidation, dissolution or winding up of the Corporation.

        (c)     Redemption

                (i)     The Class "K" Preferred Shares, or any number thereof,
                        shall be subject to redemption at an amount per share
                        equal to the amount obtained by dividing the difference
                        between the fair market value of the property (the
                        "Property") transferred to the Corporation on the
                        issuance of the Class "K" Preferred Shares and the
                        amount of any consideration (other than Redeemable
                        Preferred Shares) transferred to the transferor of the
                        Property in connection with the transfer by the number
                        of Class "K" Preferred Shares issued on the transfer of
                        the Property to the Corporation (the "Redemption
                        Amount") together with all declared but unpaid dividends
                        thereon, if any, at any time at the option of the
                        Directors without the consent of the holders thereof and
                        if less than the whole amount of the outstanding Class
                        "K" Preferred Shares shall be so redeemed, the shares to
                        be redeemed shall at any particular time, or from time
                        to time, be selected by lot or otherwise in such manner
                        as the Directors may determine. Written notice shall be
                        provided to all holders of the number of shares redeemed
                        and the notice shall provide that payment for the
                        redeemed shares shall be made at the place in Canada
                        designated in the aforesaid notice upon surrender of the
                        certificate or certificates for the shares so redeemed.
                        From and after the date of the giving of the notice of
                        redemption the Class "K" Preferred Shares called for
                        redemption shall be deemed to be redeemed and the
                        holders thereof shall have no rights whatsoever in
                        respect thereof except to receive the payment therefor
                        upon surrender of the certificate or certificates
                        representing the redeemed Class "K" Preferred Shares.
                        The Directors may make and enforce all and any other
                        such reasonable regulations not inconsistent with this
                        paragraph or the Articles or By-laws governing the
                        manner of the redemption of the Class "K" Preferred
                        Shares as they may in their sole discretion deem
                        advisable.
   14
                                      -9-

        (ii)    The Class "K" Preferred Shares or any number thereof shall be
                subject to redemption at an amount per share equal to the
                Redemption Amount together with all declared but unpaid
                dividends thereon, if any, at any time at the option of the
                holders thereof without the consent of the Directors, or the
                Corporation, provided that if the Corporation would be
                prevented by the Business Corporations Act of Alberta or any
                other law in force in the Province of Alberta from redeeming
                all of the Class "K" Preferred Shares required to be redeemed,
                then the Corporations shall redeem, disregarding fractions, that
                number of Class "K" Preferred Shares that it is permitted by
                law to redeem and the Corporation shall redeem the balance of
                the outstanding Class "K" Preferred Shares in respect of which
                redemption has been demanded by the holder at such time or
                times as the redemption is permitted by applicable law. Payment
                for such Class "K" Preferred Shares shall be made by cheque
                payable at any branch in Canada of the Corporation's bankers
                upon surrender of the certificate or certificates representing
                the Class "K" Preferred Shares to be redeemed.

        (iii)   As set out above, the Redemption Amount per share of the Class
                "K" Preferred Shares is intended to equal the difference
                between the fair market value of the Property transferred to
                the Corporation on the issuance of the Class "K" Preferred
                Shares and the amount of any consideration (other than Class
                "K" Preferred Shares) transferred to the transferor of the
                Property in connection with the transfer, divided by the number
                of Class "K" Preferred Shares issued on the transfer of the
                Property to the Corporation. Provided that should it be
                determined at any time by:

                (A) a tribunal of court of competent jurisdiction; or
                (B) agreement with the Department of National Revenue,
                    Taxation; or
                (C) agreement between the Corporation and the holder of the
                    Class "K" Preferred Shares;

                that the difference between the fair market value of the
                Property transferred to the Corporation on the issuance of the
                Class "K" Preferred Shares and the amount of any consideration
                (other than Class "K" Preferred Shares) transferred to the
                transferor of the property in connection with the transfer is
                different from the determination of such difference as made by
                the Directors on the issuance of the  Class "K" Preferred
                Shares then, in such event, subject to the Business
                Corporations Act of Alberta, the Redemption Amount as defined
                herein of the Class "K" Preferred Shares then issued and
                outstanding shall be adjusted accordingly and retroactively,
                effective as of the date of issuance of the Class "K" Preferred
                Shares to equal the amount which is obtained by dividing the
                difference (as determined pursuant to (A), (B) or (C) above, as
                the case may be) between the fair market value of the Property
                transferred to the Corporation and the amount of any
                consideration (other than Class "K" Preferred Shares)
                transferred to the trasferor by the number of Class "K"
                Preferred Shares issued upon the transfer of the Property to
                the Corporation.

        (iv)    In the event that dividends are paid on the Class "K" Preferred
                Shares between the date of issuance of the Class "K" Preferred
                Shares and the actual date of adjustment, provided for above
                then, forthwith upon any adjustment being made, an amount shall
                be paid by the Corporation or by the recipient of the dividend
                on the Class "K" Preferred Shares, as the case


     

              



       
   15
                                      -10-

                may be, together with interest thereon at the prime rate of
                interest charged by the bankers of the Corporation at the date
                of payment of the dividends computed from the date of payment
                of the dividends to the date of the payment provided for in this
                subparagraph which amount shall be equal to the difference
                between the amount of dividend actually received and the amount
                of dividend which would have been received if the aforesaid
                adjustment had actually been made at the date of issuance of the
                Class "K" Preferred Shares.

          (v)   In the event that any Class "K" Preferred Shares are redeemed
                before the actual date of any adjustment provided for above
                then, forthwith upon any adjustment being made, an amount shall
                be paid by the Corporation or the person whose Class "K"
                Preferred Shares were redeemed, as the case may be, together
                with interest thereon at the prime rate of interest charged by
                the bankers of the Corporation at the date of the redemption of
                the Class "K" Preferred Shares computed from the actual date of
                payment of the Redemption Amount to the date of the payment
                provided for in this subparagraph, which amount shall be equal
                to the difference between the amount actually paid on the
                redemption of the Class "K" Preferred Shares and the amount
                which would have been paid if the aforesaid adjustment had
                actually been made at the date of issuance of the then redeemed
                Class "K" Preferred Shares.

          (vi)  The Directors shall not allot and issue any Class "K" Preferred
                Shares or approve of the transfer of any Class "K" Preferred
                Shares unless the person to whom the shares are issued or the
                transferee, as the case may be, is made aware of the provisions
                of this paragraph and agrees, in a form and manner satisfactory
                to the Directors, to be bound by and comply with the provisions
                of this paragraph.

          (vii) Upon any adjustment being made pursuant to the provisions of
                this paragraph the stated capital of the Class "K" Preferred
                Shares shall, if the Directors decide that any adjustment to the
                stated capital of the Class "K" Preferred Shares is necessary or
                desirable, be adjusted accordingly and retroactively as of the
                date of issuance of Class "K" Preferred Shares to the amount
                determined by the Directors subject to the provisions of the
                Business Corporations Act of Alberta.

     (d)  Purchase for Cancellation

          The Corporation shall have the right at its option at any time and
          from time to time, to purchase for cancellation the whole or any part
          of the Class "K" Preferred Shares outstanding pursuant to an agreement
          between the Corporation and any holder of Class "K" Preferred Shares
          or pursuant to tenders received by the Corporation upon request for
          tenders addressed to all holders of Class "K" Preferred Shares at the
          lowest price per share at which in the opinion of the Directors such
          shares are obtainable but not exceeding the Redemption Amount of Class
          "K" Preferred Shares and from and after the date of such purchase of
          any Class "K" Preferred Shares such shares shall be regarded as having
          been redeemed; provided that, if in response to an invitation for
          tenders, two or more shareholders submit tenders at the same price and
          if such tenders are acceptable to the Corporation in whole or in part,
          then, unless the Corporation accepts all such tenders in whole, the
          Corporation shall
                
   16
                                      -11-

                    accept such tenders in proportion as nearly as may be to
                    the number of shares offered in each such tender.

2.2(D)              CLASS "L" NON-VOTING REDEEMABLE PREFERRED SHARES

                    An unlimited number of Class "L" Redeemable Preferred
Shares (in this paragraph referred to as the "Class "L" Preferred Shares") have
been created by the Corporation for the purpose of issuances in exchange for
property, (other than a promissory note or a promise to pay), and the Class "K"
Preferred Shares shall have the following rights, restrictions, privileges,
conditions and limitations:

          (a)       Dividend Rights

                    The holders of Class "K" Preferred Shares shall be entitled
                    to receive dividends as and when declared by the Directors
                    but always in preference and priority to any payment of
                    dividends on any other shares of the Corporation (except
                    any shares which by their terms are specifically stated to
                    rank prior to the Class "L" Preferred Shares in the
                    declaration and payment of dividends) out of the monies of
                    the Corporation properly applicable to the payment of
                    dividends, which dividends shall be non-cumulative
                    preferential dividends at a rate per annum equal to the
                    prescribed rate of interest for the purposes of subsection
                    256(11) of the Income Tax Act (Canada) as of the time of
                    issuance of the first then issued shares of the particular
                    class (the "Prescribed Rate"") in each case on the
                    Redemption Amount thereof (as described herein) as may be
                    determined by the Directors, payable at such time or times
                    and at such place or places as the Directors may determine.
                    The Directors shall be entitled from time to time to
                    declare part of the said non-cumulative dividend for any
                    fiscal year notwithstanding that such dividend for such
                    fiscal year shall not be declared in full. The said
                    dividends shall be non-cumulative whether earned or not
                    earned and if in any fiscal year the Directors in their
                    discretion shall not declare the said dividends or any part
                    thereof, then the right of the holders of the Preferred
                    shares to such dividends or to any undeclared part thereof
                    for the fiscal year shall be extinguished. The holders of
                    the Class "L" Preferred shares shall in no circumstances be
                    entitled to any dividends other than or in excess of the
                    non-cumulative dividends at the rate herein provided for.

          (a)       Repayment of Capital

                    In the event of the liquidation, dissolution or winding up
                    of the Corporation or other distribution of it assets
                    amongst the shareholders by way of repayment of capital,
                    the holders of the Class "I", Preferred Shares shall be
                    entitled to receive an amount per share equal to the
                    Redemption Amount (as hereinafter defined) together with
                    all declared but unpaid dividends thereon to the date of
                    the liquidation, dissolution or winding up in priority to
                    any distribution to the holders of any other shares of the
                    Corporation (except any shares which by their terms are
                    specifically stated to rank prior to the Class "L"
                    Preferred Shares in respect of such distributions) and the
                    holders of the Class "L" Preferred Shares shall have no
                    further right to participate in profits or assets in
                    respect of such liquidation, dissolution or winding up of
                    the Corporation.

          (c)       Redemption

                    (i)     The Class "L" Preferred Shares, or any number
                            thereof, shall be subject to redemption at an amount
                            per share equal to the amount obtained by
   17
                                      -12-

          dividing the difference between the fair market value of the property
          (the "Property") transferred to the Corporation on the issuance of the
          Class "L" Preferred Shares and the amount of any consideration (other
          than Class "L" Preferred Shares) transferred to the transferor of the
          Property in connection with the transfer by the number of Class "L"
          Preferred Shares issued on the transfer of the Property to the
          Corporation (the "Redemption Amount") together with all declared but
          unpaid dividends thereon, if any, at any time at the option of the
          Directors without the consent of the holders thereof and if less than
          all of the outstanding Class "L" Preferred Shares shall be so
          redeemed, the shares to be redeemed shall at any particular time, or
          from time to time, be selected by lot or otherwise in such manner as
          the Directors may determine. Written notice shall be provided to all
          holders of the number of shares redeemed and the notice shall provide
          that payment for the redeemed shares shall be made at the place in
          Canada designated in the aforesaid notice upon surrender of the
          certificate or certificates for the shares so redeemed. From and after
          the date of the giving of the notice of redemption the Class "L"
          Preferred Shares called for redemption shall be deemed to be redeemed
          and the holders thereof shall have no rights whatsoever in respect
          thereof except to receive the payment therefor upon surrender of the
          certificate or certificates representing the redeemed Class "L"
          Preferred Shares. The Directors may make and enforce all and any other
          such reasonable regulations not inconsistent with this paragraph or
          the Articles or By-laws governing the manner of the redemption of the
          Class "L" Preferred Shares as they may in their sole discretion deem
          advisable.

(ii)      The Class "L" Preferred Shares or any number thereof shall be subject
          to redemption at an amount per share equal to the Redemption Amount
          together with all declared but unpaid dividends thereon, if any, at
          any time at the option of the holders thereof without the consent of
          the Directors, or the Corporation, provided that if the Corporation
          would be prevented by the Business Corporations Act of Alberta or any
          other law in force in the Province of Alberta from redeeming all of
          the Class "L" Preferred Shares required to be redeemed, then the
          Corporation shall redeem, disregarding fractions, that number of Class
          "L" Preferred Shares that it is permitted by law to redeem and the
          Corporation shall redeem the balance of the outstanding Class "L"
          Preferred Shares in respect of which redemption has been demanded by
          the holder at such time or times as the redemption is permitted by
          applicable law. Payment for such Class "L" Preferred Shares shall be
          made by cheque payable at any branch in Canada of the Corporation's
          bankers upon surrender of the certificate or certificates representing
          the Class "L" Preferred Shares to be redeemed.

(iii)     As set out above, the Redemption Amount per share of the Class "L"
          Preferred Shares is intended to equal the difference between the fair
          market value of the Property transferred to the Corporation on the
          issuance of the Class "L" Preferred Shares and the amount of any
          consideration (other than Class "L" Preferred Shares) transferred to
          the transferor of the Property in connection with the transfer,
          divided by the number of Class "L" Preferred Shares issued on the
          transfer of the Property to the Corporation. Provided that should it
          be determined at any time by:


   18
                                      -13-

                        (A)  a tribunal of court of competent jurisdiction; or 
                        (B)  agreement with the Department of National Revenue,
                              Taxation; or
                        (C)  agreement between the Corporation and the holder of
                             the Class "L" Preferred Shares;

                        that the difference between the fair market value of the
                        Property transferred to the Corporation on the issuance
                        of the Class "L" Preferred Shares and the amount of any
                        consideration (other than Class "L" Preferred Shares)
                        transferred to the transferor of the property in
                        connection with the transfer is different from the
                        determination of such difference as made by the
                        Directors on the issuance of the Class "L" preferred
                        Shares then, in such event, subject to the Business
                        Corporations Act of Alberta, the Redemption Amount as
                        defined herein of the Class "L" Preferred Shares then
                        issued and outstanding shall be adjusted accordingly and
                        retroactively, effective as of the date of issuance of
                        the Class "L" Preferred Shares to equal the amount which
                        is obtained by dividing the difference (as determined
                        pursuant to (A), (B) or (C) above, as the case may be)
                        between the fair market value of the Property
                        transferred to the Corporation and the amount of any
                        consideration (other than Class "L" Preferred Shares)
                        transferred to the transferor by the number of Class "L"
                        Preferred Shares issued upon the transfer of the
                        Property to the Corporation.

                (iv)    In the event that dividends are paid on the Class "L"
                        Preferred Shares between the date of issuance of the
                        Class "L" Preferred Shares and the actual date of any
                        adjustment provided for above then, forthwith upon any
                        adjustment being made, an amount shall be paid by the
                        Corporation or by the recipient of the dividend on the
                        Class "L" Preferred Shares, as the case may be, together
                        with the interest thereon at the prime rate of interest
                        charged by the bankers of the Corporation at the date of
                        payment of the dividends computed from the date of
                        payment of the dividends to the date of the payment
                        provided for in this subparagraph which amount shall be
                        equal to the difference between the amount of dividend
                        actually received and the amount of dividend which would
                        have been received if the aforesaid adjustment had
                        actually been made at the date of issuance of the Class
                        "L" Preferred Shares.
         
                (v)     In the event that any Class "L" Preferred Shares are
                        redeemed before the actual date of any adjustment
                        provided for above then, forthwith upon any adjustment
                        being made, an amount shall be paid by the Corporation
                        or the person whose Class "L" Preferred Shares were
                        redeemed, as the case may be, together with interest
                        thereon at the prime rate of interest charged by the
                        bankers of the Corporation at the date of the redemption
                        of the Class "L" Preferred Shares computed from the
                        actual date of payment of the Redemption Amount to the
                        date of the payment provided for in this subparagraph,
                        which amount shall be equal to the difference between
                        the amount actually paid on the redemption of the Class
                        "L" Preferred Shares and the amount which would have
                        been paid if the aforesaid adjustment had actually been
                        made at the date of issuance of the then redeemed Class
                        3 Preferred Shares.

                (vi)    The Directors shall not allot and issue any Class "L"
                        Preferred Shares or approve of the transfer of any Class
                        "L" Preferred Shares unless the person

                        to whom the shares are issued or the transferee, as the
                        case may be, is made aware of the provisions of this
                        paragraph and agrees, in a form and manner satisfactory
                        to the Directors, to be bound by and comply with the
                        provisions of this paragraph.

                (vii)   Upon any adjustment being made pursuant to the
                        provisions of this paragraph the stated capital of the
                        Class "L" Preferred Shares shall, if the Directors
                        decide that any adjustment to the stated capital of the
                        Class "L" Preferred Shares is necessary or desirable,
                        be adjusted accordingly and retroactively as of the
                        date of issuance of the Class "L" Preferred Shares to
                        the amount determined by the Directors subject to the
                        provisions of the Business Corporations Act of Alberta.

        (d)     Purchase for Cancellation

                The Corporation shall have the right at its option at any time
                and from time to time, to purchase for cancellation the whole
                or any part of the Class "L" Preferred Shares outstanding
                pursuant to an agreement between the Corporation and any holder
                of Class "L" Preferred Shares or pursuant to tenders received
                by the Corporation upon request for tenders addressed to all
                holders of Class "L" Preferred Shares at the lowest price per
                share at which in the opinion of the Directors such shares are
                obtainable but not exceeding the Redemption Amount of Class "L"
                Preferred Shares and from and after the date of such purchase
                of any Class "L" Preferred Shares such shares shall be regarded
                as having been redeemed; provided that, if in response to an
                invitation for tenders, two or more shareholders submit tenders
                at the same price and if such tenders are acceptable to the
                Corporation in whole or in part, then, unless the Corporation
                accepts all such tenders in whole, the Corporation shall accept
                such tenders in proportion as nearly as may be to the number of
                shares offered in each such tender.

2.3             OTHER RIGHTS OF THE REDEEMABLE PREFERRED SHARES

                Notwithstanding anything contained in this or any other
Schedule to the Articles of the Corporation or the Articles of the Corporation,
the Class "J" Voting Redeemable Preferred Shares and the Class "K" and "L"
Non-Voting Redeemable Preferred Shares and the Class "K" and "L" Non-Voting
Redeemable Preferred Shares shall rank pari passu with each other in respect
of all distributions on the liquidation, dissolution or winding up of the
Corporation but, for greater certainty, such classes of shares need not rank
equally or be treated equally in respect of redemptions made at the option of
the Corporation pursuant to the provisions of this Schedule or any other
Schedule to the Articles of the Corporation, or in the declaration or payment
of dividends and the Directors of the Corporation shall have full and absolute
discretion to declare and pay dividends, subject to the limitations in the
provisions of this Schedule, or any other Schedule to the Articles of the
Corporation, in such amounts, at such time and in such manner as the Directors

Class "K" Preferred Shares and the Class "L" Preferred Shares.

                Notwithstanding anything contained in or forming a part of this
or any other Schedule to the Articles of the Corporation or the Articles of the
Corporation, no dividends shall at any time be declared or paid on any shares
and no share shall be redeemed, purchased or otherwise acquired where the
payment of such dividend or the payment of the redemption, purchase or
acquisition price, as the case may be, would have the result of reducing the net
realizable value of

     the assets of the Corporation to an amount that is less than the amount
     required to redeem all redeemable preferred shares of the Corporation then
     issued and outstanding and for the purposes of this paragraph, the net
     realizable value of the assets of the Corporation could be realized in
     cash at the time less the aggregate of the liabilities of the Corporation
     at that time.

                        out of all or any profits or surplus available for
                        dividends, to non-cumulative dividends at the rate of
                        eight (8%) per cent per annum on the Redemption Amount
                        thereof (as described in subsection 2.2(c) herein) as
                        may be determined by the Directors, payable at such

                        Directors may determine. The said dividends shall be
                        non-cumulative whether earned or not earned, and if in
                        any fiscal year the Directors in their discretion shall
                        not declare the said dividends or any part thereof,
                        then the right of the holders of the Class "D" shares
                        to such dividends or any greater dividend actually
                        declared for the fiscal year shall be extinguished. The
                        holders of the Class "D" shares shall in no
                        circumstances be entitled to any dividends other than or

               (ii)     Exclusive

                        Dividends on any class of shares of the Corporation may
                        be declared and paid exclusive of dividends in respect

                        No dividends or distributions of any kind whatsoever
                        shall be declared or made in respect of any of the
                        shares of the Corporation which would be contrary to
                        any applicable law or which would have the effect of
                        reducing the net assets, including goodwill, of the
                        Corporation to an amount insufficient to enable the
                        redemption by the Corporation, at the aggregate of the
                        Redemption Amounts, of the issued and outstanding Class
                        "D" shares.

        (c)     Redemption Amount of Class "D" Shares

                (i)     The Redemption Amount for each Class "D" share shall be
                        equal to the fair market value of the property or
                        issued shares of the Corporation of a different class
                        (the "Assets") for which Class "D" shares were issued
                        by the Corporation (the "Asset Value") less the
                        aggregate value of any non-share consideration given or
                        assumed by the Corporation as partial consideration for
                        the Assets (the "Non-Share Value") divided by the
                        number of Class "D" shares issued in exchange for the
                        Assets.

                (ii)    Notwithstanding the provisions of the foregoing
                        paragraph 2.2(c)(i) hereof, if the Minister of National
                        Revenue, the Provincial Treasurer of the Province of
                        Alberta, their authorized representative or any similar
                        authority shall assess or reassess the Corporation or
                        its shareholders for income tax (or propose such an
                        assessment or reassessment) on the basis of a
                        determination or assumption that:

                        (A)     the fair market value of the Assets received in
                                respect of the issuance of any Class "D" share
                                does not equal the Asset Value; or

                        (B)     the Non-Share Value should have been a greater
                                or lesser amount than the amount determined
                                upon issuance of such Class "D" share;
   23
                                      -3-

                  then the Asset Value shall be adjusted (the "Adjusted Asset
                  Value") or the Non-Share Value shall be adjusted (the
                  "Adjusted Non-Share Value"), as the case may be, and shall be
                  deemed to be:

                  (C)   subject to subparagraph (E), hereof, the fair market
                        value of the Assets or Non-Share Value as determined by
                        the authority making or proposing such an assessment or
                        reassessment, provided that the Directors agree that
                        such determination is accurate; or

                  (D)   subject to subparagraph (E) hereof, where the 
                        Directors do not agree that the authority's
                        determination is accurate, the fair market value of the
                        Assets or Non-Share Value as determined by a qualified
                        person whom the Directors shall appoint to make that
                        determination forthwith following the making or
                        proposing of such an assessment or reassessment; or

                  (E)   where any such assessment or reassessment is the subject
                        of an appeal to a Court of competent jurisdiction, the
                        fair market value of the Assets or Non-Share Value as
                        determined by that Court.

           (iii)  In the event of a determination of an Adjusted Asset Value or
                  an Adjusted Non-Share Value then the Redemption Amount
                  payable for each Class "D" share issued in exchange for the
                  Assets shall be adjusted by the Directors and shall be equal
                  to the Adjusted Asset Value (or if there has been no
                  adjustment the Asset Value) less the Adjusted Non-Share Value
                  (or if there has been no adjustment the Non-Share Value)
                  divided by the total number of Class "D" shares issued in
                  exchange for the Assets. If any Non-Share consideration shall
                  have been given or assumed, any Class "D" share shall have
                  been redeemed or any dividends shall have been declared
                  thereon prior to the Redemption Amount being adjusted as
                  aforesaid, any resulting over-payment by the Corporation
                  shall be a debt due on demand to the Corporation from the
                  holder of such Class "D" shares and any resulting
                  under-payment shall be a debt due on demand from the
                  Corporation to the holders of such Class "D" shares.

      (d)  Procedure

           (i)    Subject to the Business Corporations Act, the Corporation
                  may, upon giving notice as hereinafter provided, redeem the
                  whole or any part of the Class "D" shares on payment for each
                  Class "D" share to be redeemed of the Redemption Amount,
                  together with all dividends declared thereon and unpaid.
                  Unless waived by the registered holder of the shares to be
                  redeemed, the Corporation shall give not less than thirty
                  (30) days notice in writing of such redemption by mailing
                  such notice to the registered holder of each Class "D" share
                  to be redeemed, specifying the date and place or places of
                  redemption. If notice of any such redemption be given by the
                  Corporation in the manner aforesaid and an amount sufficient
                  to redeem such shares be deposited with any trust company or
                  chartered bank in Canada as specified in the notice on or
                  before the date fixed for redemption, dividends on the Class
                  "D" shares to be redeemed shall cease after the date so fixed
                  for redemption and the holders thereof shall thereafter have
                  no rights against the Corporation in respect thereof except,
                  upon the surrender of certificates for such Class "D" shares,
                  to receive payment therefor out of the monies so deposited.
                  Upon the Redemption
   24
                                      -4-



               Amount of such Class "D" shares being deposited with any trust
               company or chartered bank in Canada as aforesaid, notice shall be
               given to the holders of the Class "D" shares called for
               redemption who have failed to present the certificates
               representing such Class "D" shares, within two (2) months of the
               date specified for redemption, to the effect that the monies have
               been so deposited and may be obtained by the holders of the said
               Class "D" shares upon presentation of the certificates
               representing such Class "D" shares for redemption at the said
               trust company or chartered bank in Canada.

(e)  Retractable

     (i)       Each holder of a Class "D" share has the right, exercisable by
               depositing the holder's share certificate with the Corporation at
               its registered office, to require the Corporation to redeem any
               Class "D" share within thirty (30) days after the date the
               certificate is deposited, for an amount equal to one hundred
               (100%) per cent of the Redemption Amount per Class "D" share so
               deposited, together with all dividends declared thereon and
               unpaid. The Corporation will not be obligated to redeem any Class
               "D" share pursuant to this provision if and so long as the
               redemption would be contrary to any applicable law.

(f)  Liquidation

     In the event of the liquidation, dissolution or winding up of the
     Corporation, whether voluntary or involuntary:

     (i)       the holders of the Class "D" shares shall be entitled to receive
               before distribution of any part of the assets of the Corporation
               amongst the holders of shares of any other class in the share
               capital of the Corporation, an amount equal to one hundred (100%)
               per cent of the Redemption Amount of the Class "D" shares and any
               dividends declared thereon and unpaid and no more;

               the Class "B" and "C" shares in the share capital of the
               Corporation, an amount equal to the quotient obtained when the
               stated capital maintained for the Class "A" shares is divided by
               the number of Class "A" shares then outstanding;

     (iii)     the holders of the Class "B" shares shall be entitled to receive
               in respect of each Class "B" share held, before distribution of
               any part of the assets of the Corporation amongst the holders of
               the Class "C" shares in the share capital of the Corporation, an
               amount equal to the quotient obtained when the stated capital
               maintained for the Class "B" shares is divided by the number of
               Class "B" shares then outstanding;

     (iv)      the holders of the Class "C" shares shall be entitled to receive
               in respect of each Class "C" share held, before distribution of
               any part of the assets of the Corporation amongst the holders of
               any other class of shares in the share capital of the Corporation
               other than a distribution pursuant to

                        an amount equal to the quotient obtained when the
                        stated capital maintained for the Class "C" shares is
                        divided by the number of Class "C" shares then
                        outstanding; and

                (v)     the holders of the Class "A", "B" and "C" shares shall
                        be entitled to participate equally amongst themselves
                        in respect of each Class "A", "B" and "C" share held in
                        any further distribution of the assets of the

                           THIS IS SCHEDULE "A" TO THE

                           ARTICLES OF INCORPORATION
                            DATED AUGUST 18, 1987 OF
                        RIVERVIEW MANAGEMENT CORPORATION

2.0  The authorized capital of the Corporation is to consist of three classes of
     shares: 1) an unlimited number of Class A voting common shares without
     nominal or par value ("Voting Common Shares"), 2) an unlimited number of
     Class B non-voting common shares without nominal or par value ("Non-Voting
     Common Shares"), and 3) an unlimited number of non-voting redeemable
     preferred shares ("Redeemable Preferred Shares").

2.1  The maximum price or consideration at or for which the Voting Common Shares
     or the Non-Voting Common Shares may be issued or sold is not limited in
     amount, and the maximum price or consideration at or for which the
     Redeemable Preferred Shares may be issued or sold is not limited in amount,
     provided however, that the Voting Common Shares, the Non-Voting Common
     Shares and the Redeemable Preferred Shares may be issued and sold by the
     Corporation each from time to time by resolution of the Directors of the
     Corporation.

2.2  The rights attaching to the Redeemable Preferred Shares to the Voting
     Common Shares and to the Non-Voting Common Shares shall be as follows:

     (a)  The holder of Voting Common Shares shall be entitled to one (1) vote
          for each Voting Common Share. The holders of Non-Voting Common Shares
          shall not be entitled to a vote for any Non-Voting Common Share.

     (b)  All or part of the Redeemable Preferred Shares at any time
          outstanding may at any time and from time to time be purchased or be
          redeemed by the Corporation on any date fixed by the Corporation at
          an amount equal to the capital paid up thereon.

     (c)  In the event of liquidation, dissolution or winding-up of the
          Corporation or other distribution of its assets to the shareholders
          for the purpose of winding up its affairs, the holders of the
          Redeemable Preferred Shares shall be entitled to receive the amount
          paid up on such shares before any amount is paid or any property or
          assets of the Corporation are distributed to the holders of any
          Voting Common Shares or Non-Voting Common Shares or shares of any
          other class ranking junior to the Redeemable Preferred Shares. Upon
          payment of the amounts payable to them as provided above, the said
          holders of the Redeemable Preferred Shares shall not be entitled to
          share in any further distribution of the property or assets of the
          Corporation.

     (d)  The holders of the Redeemable Preferred Shares shall not be entitled
          as of right to subscribe for or purchase or receive any part of any
          issue of shares or bonds, debentures or other securities of the
          Corporation now or hereafter authorized.

2.3  The capital of the Corporation may be increased, divided, converted,
consolidated and dealt with in accordance with the law then prevailing and new
capital may be issued having attached thereto any preferred, special, qualified
or deferred rights, privileges, conditions or restrictions, including any
preference or priority in the payment of dividends or the distribution of
assets, or voting or otherwise over any other shares, whether common or
preferred, and whether issued or not.

2.4  Any and all shares of the Corporation may be issued at the times and to the
person and for the consideration that the directors determine. The shares of
each class may be issued in one or more series and the directors may fix the
number of shares in each series and determine the designation, rights,
privileges, restrictions and conditions attaching to the shares of each series.

                        RIVERVIEW MANAGEMENT CORPORATION


(a)  the number of members for the time being shall be limited to fifty (50)

who, having been formerly in the employment of the Corporation, were while in
such employment and have continued after the termination of such employment to

article, be treated as a single member;

(b)  no invitation shall be made to the public to subscribe for any shares,
debentures or other securities of the Corporation;

(c)  the right of the Shareholders to transfer or dispose of their shares shall

   31
                          THIS IS SCHEDULE "C" TO THE
                           ARTICLES OF INCORPORATION
                            DATED AUGUST 18, 1987 OF

                        RIVERVIEW MANAGEMENT CORPORATION


6.0  The Directors of the Corporation from time to time may, without
     authorization of the shareholders:

     (a)  borrow money upon the credit of the Corporation;

     (b)  issue, re-issue, sell or pledge bonds, debentures, notes or other
          evidence of indebtedness or guarantee of the Corporation, whether
          secured or unsecured;

     (c)  give a guarantee on behalf of the Corporation to secured performance
          of any person; and

     (d)  charge, mortgage, hypothecate, pledge or otherwise create a security
          interest in all or any currently owned or subsequently acquired real
          or personal, movable or immovable property of the Corporation
          including book debts, rights, powers, franchises and undertaking, to
          secure any obligation, present or future, of the Corporation.

The Directors may, from time to time, delegate to such one or more of the
Directors or Officers of the Corporation as may be designated by the Directors
all or any of the powers conferred on the Directors by the foregoing or by the
Business Corporations Act, to such extent and in such manner as the Directors
shall determine at the time of each such delegation. Nothing in this provision
limits or restricts the borrowing of money by the Corporation on bill of
exchange or promissory notes made, drawn, accepted or endorsed by or on behalf
of the Corporation.

6.1  The Directors may, between annual general meetings, appoint one or more
     additional  directors of the Corporation to serve until the next annual
     general meeting, but the number of additional Directors shall not at any
     time exceed one-third of the number of Directors who held office at the
     expiration of the last annual meeting of the Corporation.

6.2  Directors of the Corporation shall be elected for terms not later than the
     close of the third annual meeting following their election. The terms of
     office of each director shall be staggered as required from time to time
     to ensure that as close to one-third of the board as may be reasonably
     practicable shall be up for election at each annual meeting of
     shareholders to be held for the next 3 annual meeting of shareholders
     following the election. If neither the resolution, notice of meeting or
     information circular relating to a meeting at which directors are to be
     elected for varying terms of office specify the term for each individual
     director, the director or directors receiving the most votes shall serve
     the longest terms, and for such purposes where two or more nominees
     receive the same number of votes, a nominee whose name appears prior to
     any other nominee or nominees in the resolution electing the directors
     shall be deemed to have a greater number of votes than such other nominee
     or nominees.
