    	8



    	 



    

 


(v)              
the permissive rights of the Trustee to do things enumerated in the Indenture shall not be construed as a duty and the Trustee
shall not be answerable for other than its negligence or willful misconduct;


 


(vi)            
the rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right
to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder (including as
Security Registrar or, if applicable, Paying Agent), and to each agent, custodian, and any other such Persons employed to act
hereunder;
