                          reorganization or other  transaction  affecting Parent
                          Common  Shares,  the  effect  thereof  upon  the  then
                          outstanding Parent Common Shares; and

                  (v)     in all such cases, the general  taxation  consequences
                          of the  relevant  event  to  holders  of  Exchangeable
                          Shares to the extent that such consequences may differ
                          from the  taxation  consequences  to holders of Parent
                          Common  Shares  as a  result  of  differences  between
                          taxation laws of Canada and the United States  (except
                          for any differing  consequences arising as a result of
                          differing  marginal  taxation rates and without regard
                          to  the   individual   circumstances   of  holders  of
                          Exchangeable Shares).

         (c)      Purchaser agrees that, to the extent required, upon due notice
                  from  Parent,  Mergeco  will use its best  efforts  to take or
                  cause  to be taken  such  steps  as may be  necessary  for the
                  purposes of ensuring  that  appropriate  dividends are paid or
                  other  distributions  are made by  Mergeco,  or  subdivisions,
                  redivisions or changes are made to the Exchangeable Shares, in
                  order to  implement  the  required  economic  equivalent  with
                  respect to the Parent Common Shares and Exchangeable Shares as
                  provided for in this section 2.7.

2.8      Tender Offers

In the event that a tender offer,  share exchange offer,  issuer bid,  take-over
bid or similar  transaction with respect to Parent Common Shares (an "Offer") is
proposed  by  Parent  or is  proposed  to  Parent  or  its  shareholders  and is
recommended by the Board of Directors of Parent, or is otherwise  effected or to
be effected  with the consent or approval of the Board of  Directors  of Parent,
and the  Exchangeable  Shares are not redeemed by Mergeco or purchased by Parent
pursuant  to  the  Call  Rights,   Parent  will  use  its   reasonable   efforts
expeditiously  and in good faith to take all such actions and do all such things
as are  necessary  or  desirable  to enable and permit  holders of  Exchangeable
Shares (other than Parent and its  Affiliates)  to  participate in such Offer to
the same extent and on an economically equivalent basis as the holders of Parent
Common Shares,  without  discrimination.  Without limiting the generality of the
foregoing,  Parent will use its  reasonable  efforts  expeditiously  and in good
faith to ensure that holders of Exchangeable Shares may participate in each such
Offer without being required to retract  Exchangeable  Shares as against Mergeco
(or, if so required, to ensure that any such retraction, shall be effective only
upon, and shall be  conditional  upon, the closing of such Offer and only to the
extent necessary to tender or deposit to the Offer). Nothing herein shall affect
the rights of Mergeco to redeem  (or  Parent to  purchase  pursuant  to the Call
Rights)  Exchangeable  Shares,  as applicable,  in the event of a Parent Control
Transaction.

2.9   Ownership of Outstanding Shares

<PAGE>
                                                                               9

Without the prior  approval of Mergeco and the prior  approval of the holders of
the  Exchangeable  Shares  given in  accordance  with  section 10.2 of the Share
Provisions,  Parent covenants and agrees in favour of Purchaser that, as long as
any outstanding Exchangeable Shares are owned by any Person other than Parent or
any of its  Affiliates,  Parent  will  be and  remain  the  direct  or  indirect
beneficial  owner of all issued and outstanding  voting shares in the capital of
Mergeco.

2.10     Parent and Affiliates Not to Vote Exchangeable Shares

Parent  covenants  and agrees  that it will  appoint  and cause to be  appointed
proxyholders  with  respect  to all  Exchangeable  Shares  held  by it  and  its
Affiliates  for the sole  purpose  of  attending  each  meeting  of  holders  of
Exchangeable  Shares in order to be  counted as part of the quorum for each such
meeting.  Parent  further  covenants and agrees that it will not, and will cause
its  Affiliates  not to,  exercise any voting rights which may be exercisable by
holders  of  Exchangeable  Shares  from  time  to  time  pursuant  to the  Share
Provisions  or pursuant to the  provisions of the Act (or any successor or other
corporate  statute by which Mergeco may in the future be governed)  with respect
to any  Exchangeable  Shares held by it or by its  Affiliates  in respect of any
matter considered at any meeting of holders of Exchangeable Shares.

2.11     Rule 10b-18 Purchases

For certainty, nothing contained in this Agreement, including without limitation
the  obligations  of Parent  contained  in section 2.8  hereof,  shall limit the
ability of Parent or Mergeco to make a "Rule 10b-18  Purchase" of Parent  Common
Shares pursuant to Rule 10b- 18 of the United States Securities  Exchange Act of
1934, as amended.

Parent shall not consummate any transaction  (whether by way of  reconstruction,
reorganization,  consolidation,  merger,  transfer,  sale,  lease or other-wise)
whereby all or substantially  all of its undertaking,  property and assets would
become the  property  of any other  Person  or, in the case of a merger,  of the
continuing corporation resulting therefrom unless, but may do so if:

         (a)      such  other  Person or  continuing  corporation  (the  "Parent
                  Successor") by operation of law, becomes,  without more, bound
                  by the terms and  provisions  of this  Agreement or, if not so

                  supplemental hereto and such other instruments (if any) as are
                  reasonably  necessary or advisable to evidence the  assumption
                  by the Parent  Successor of liability  for all moneys  payable
                  and property  deliverable  hereunder  and the covenant of such
                  Parent  Successor  to pay and deliver or cause to be delivered
                  the same and its  agreement  to observe  and  perform  all the
                  covenants and obligations of Parent under this Agreement; and

         (b)      such  transaction  shall be upon such terms and  conditions as
                  substantially  to preserve  and not to impair in any  material
                  respect any of the rights,  duties,  powers and authorities of
                  the other parties hereunder.

and power of Parent under this  Agreement in the name of Parent or otherwise and
any act or proceeding by any provision of this Agreement  required to be done or
performed  by the Board of  Directors of Parent or any officers of Parent may be
done and  performed  with like force and effect by the  directors or officers of
such Parent Successor.

3.3      Wholly-Owned Subsidiaries

Nothing  herein shall be construed as preventing the  amalgamation  or merger of
any wholly-owned  direct or indirect subsidiary of Parent with or into Parent or
the  winding-up,  liquidation or dissolution of any  wholly-owned  subsidiary of
Parent  provided that all of the assets of such  subsidiary  are  transferred to
Parent or another  wholly-owned  direct or indirect subsidiary of Parent and any
such transactions are expressly permitted by this Article 3.

other than Parent and any of its Affiliates.

4.2      Changes in Capital of Parent and Mergeco

                                                                              11

At all times after the occurrence of any event contemplated pursuant to sections
2.7 and 2.8  hereof or  otherwise,  as a result of which  either  Parent  Common
Shares or the Exchangeable Shares or both are in any way changed, this agreement
shall  forthwith  be amended and  modified as  necessary  in order that it shall
apply with full force and effect,  mutatis mutandis,  to all new securities into

the parties  hereto shall  execute and deliver an  agreement  in writing  giving
effect to and evidencing such necessary amendments and modifications.

If  any  provision  of  this  Agreement  is  held  to  be  invalid,  illegal  or

                  the Board of  Directors of each of Mergeco and Parent shall be
                  of the good  faith  opinion  that such  additions  will not be
                  prejudicial  to the rights or  interests of the holders of the
                  Exchangeable Shares;

         (b)      making such amendments or modifications  not inconsistent with
                  this  Agreement as may be necessary or desirable  with respect
                  to matters or questions  which,  in the good faith  opinion of

                  Directors  shall  be of  the  good  faith  opinion  that  such

                  provision or clerical omission or mistake

                  or manifest  error,  provided  that the Boards of Directors of
                  each of Mergeco and Parent shall be of the good faith  opinion
                  that such changes or  corrections  will not be  prejudicial to
