If any of the Mortgaged Property may not be mortgaged, charged or assigned, or if a security interest may not be created therein by the Chargor in favour of the Bank (because the consent or approval of a third party or parties is required and such consent or approval has not been obtained or the requirement therefor waived as of the date hereof and if the failure to obtain such consent or approval renders the mortgage, charge, assignment or security interest hereunder invalid and/or unenforceable or because rights appurtenant to the Mortgaged Property would not, as a matter of law, pass to the Bank as an incidence of the mortgages, charges, assignments or security interests made pursuant to this Debenture) the Chargor shall hold such Mortgaged Property and all benefits derived thereunder in trust for the Bank.
