either:

     

    
      	
               
      

            	
              (a)

            	
              it
      is necessary to change the Elected Amount of the Asset to comply with the

      or

      different than the amount agreed upon between the Vendor and
      Purchaser,

            


    

     

    then in
order to comply with the common intentions of the Vendor and Purchaser as
hereinbefore expressed, the parties shall do all things reasonably necessary to
reflect such change including, for example, filing an amended joint election
pursuant to subsection 85(1) of the Tax Act.

      TRUST

Vendor acknowledges and declares that until such time as title to any Asset has
been recorded in the name of the Purchaser, the Vendor shall hold the legal
title to such Asset in trust as a bare trustee for the Purchaser.

              BENEFITS OF UNASSIGNED
      CONTRACTS

            


    

     

    8.1                    
Subject to Sections 8.2 and 8.3, if this Agreement, or any other document or
instrument of conveyance which may from time to time be executed and delivered
by the Vendor, fails to convey to the Purchaser any right in or to an Asset
intended to be conveyed to the Purchaser in accordance with the Arrangement
Agreement, the Vendor shall hold such Asset in trust for the benefit of the
Purchaser and execute and deliver such further items as the Purchaser may from
time to time direct in accordance with Section 9.1.

     

    8.2                     If
the Vendor cannot lawfully convey to the Purchaser any right in or to an Asset,
including without limitation any right pursuant to a contract, lease, licence or
other document because:

     

    
      	
               
      

            	
              (a)

            	
              the
      terms of any document governing such right prohibit or restrict such
      assignment,

            


    

     

    
      	
               
      

            	
              (b)

            	
              the
      terms of any document governing such right provide that the right may only
      be assigned if the consent of one or more third parties is obtained to
      such assignment and any such consent has not been obtained,
    or

            


    

     

    
      	
               
      

            	
              (c)

            	
              such
      an assignment would contravene any applicable law or any decree, order,
      regulation or other rule of any authority having jurisdiction
      (collectively, “Applicable
      Law”),

            


    

     

    then such
right shall not be conveyed pursuant to Section 3. In such event, to the extent
permitted by law and in a manner approved by the Purchaser in writing, the
Vendor will provide the Purchaser with the benefits of such right and enforce
such right for the benefit of the Purchaser.

     

    8.3                   
To the extent that the Purchaser is provided with the benefits of any right
pursuant to Section 8.2, the Purchaser will, to the extent that it is able to do
so, perform the obligations of the Vendor under or in connection with such
right, but only to the extent that such performance would not result in any
breach or default under any document governing such right or Applicable
Law.
