The Borrower agrees to defend, indemnify, and hold the Agent, each Lender and each other Released Party harmless from and against any and all losses, costs, expenses, damages, or liabilities (including reasonable attorneys’ fees) incurred in connection with any demand, claim, counterclaim, cause of

action, or proceeding brought as a result of, or arising out of, or in any way related to any of the Loan Documents, this Amendment No. 6, any documents executed in connection with or related to any of the Loan Documents, the performance by the Agent and each Lender under any of the Loan Documents or any documents executed in connection with or related to this Amendment No. 6 or any of the other Loan Documents, or any transaction financed or to be financed, in whole or in part, directly or indirectly, with the proceeds of any Loans.
