the Administrative Agent, who must in turn send copy of them to the Banks within the 3 (three) days following reception, in the understanding that the Joint Obligors and the Borrower are not responsible for such copy. Consistent with the foregoing,

agents or attorneys-in-fact.

 37 

 
misconduct. Without limitation of the foregoing, each Bank shall reimburse the Administrative Agent upon demand for its ratable share of any costs or out-of-pocket expenses (including Attorney
Costs) incurred by the Administrative Agent in connection with the preparation, execution, delivery, modification, amendment or enforcement (whether through negotiations, legal proceedings or otherwise) of, or legal advice in respect of rights or
